Description
Technical Field
The present invention relates to an electrical connector assembly in which a first connector and a second connector are fitted together, and a circuit board to which the electrical connector assembly is mounted.
Background
For example, patent document 1 discloses an electrical connector assembly composed of a plug connector having signal contacts and a housing, and a receptacle connector, respectively. Each signal contact (hereinafter, referred to as a connection terminal) extends in the insertion/extraction direction when the plug connector and the receptacle connector are fitted, and the long side direction of the connection terminal is in the insertion/extraction direction. The contact portion of one connecting terminal is in contact with the vicinity of the protruding portion of the other connecting terminal, whereby the one connecting terminal and the other connecting terminal are electrically connected. The direction of the contact pressure (i.e., the pressing direction of the signal contact) when the contact portion contacts the vicinity of the protruding portion is orthogonal to the insertion/extraction direction. The protruding portion of the connection terminal is provided on the opposite side to the side where the contact portions contact each other, in order to prevent deformation in the vicinity of the protruding portion during connection.
Patent document 1: japanese patent laid-open publication No. 2005-190815
In the electrical connector assembly of patent document 1, since the longitudinal direction of the connection terminal is along the insertion/extraction direction, the connection terminal needs to have a predetermined insertion/extraction direction length in order to ensure a predetermined contact pressure, and it is difficult to reduce the connector height.

the above-described electrical connector assembly is characterized in that,
the first connector has a first connection terminal, and the second connector has a second connection terminal,
the first connection terminal has a first contact portion extending toward the second connection terminal facing each other at the time of fitting and having a free end portion having elasticity,
when the first contact portion is fitted, the first contact portion is pressed against the second connection terminal in the insertion/extraction direction.
A circuit board to which a power supply connector assembly according to another aspect of the present invention is mounted includes:
the above-mentioned electric connector assembly; and
a first circuit substrate and a second circuit substrate,

In the present specification, "the contact portion is pressed against the connection terminal in the insertion/extraction direction" means that the direction of pressing between the contact portion and the connection terminal is inclined in an angle range from minus 45 degrees to plus 45 degrees with respect to the insertion/extraction direction, in addition to the same direction as the insertion/extraction direction.
According to the present invention, since the first contact portion is pressed against the second connection terminal in the insertion/extraction direction, the spring height of the first contact portion in the insertion/extraction direction required to secure a predetermined contact pressure is reduced, and thus, the first connector can be made smaller, and further, the electrical connector assembly can be made smaller.

Detailed Description
Hereinafter, embodiments of the electrical connector assembly 1 and the circuit board 2 to which the electrical connector assembly 1 is attached according to the present invention will be described with reference to the drawings. In each of the drawings, for convenience of explanation, the X-axis, the Y-axis, and the Z-axis are shown to be orthogonal to each other. The X-axis direction is the longitudinal direction of the electrical connector assembly 1, the Y-axis direction is the longitudinal orthogonal direction of the electrical connector assembly 1, and the Z-axis direction is the insertion/removal direction of the electrical connector assembly 1.
[ electric connector assembly ]
Fig. 1 is a perspective view showing an electrical connector assembly 1 according to an embodiment.
As shown in fig. 1, the electrical connector assembly 1 includes a first connector 10 and a second connector 20 that is fitted to the first connector 10 so as to be pluggable in a plugging direction (Z-axis direction). The electrical connector assembly 1 is configured such that the first connector 10 and the second connector 20 are fitted to each other or released from fitting by moving the second connector 20 in the insertion/removal direction (Z-axis direction) toward the first connector 10 in a state where the second connector 20 is opposed to the first connector 10.
[ first connector ]
Fig. 2 is a perspective view of the first connector 10 constituting the electrical connector assembly 1 shown in fig. 1.
As shown in fig. 2, the first connector 10 has a first insulating member 11, a plurality of first connection terminals 14, and a first external ground member 36. As the first insulating member 11, for example, an electrically insulating resin such as a liquid crystal polymer is used. The first insulating member 11 has a first mounting support portion 12 located at the substantially center in the longitudinal direction (X-axis direction) of the first connector 10. Fitting recesses 38 recessed in the insertion and removal direction (negative direction in the Z-axis direction) and having steps are formed on both sides sandwiching the first mounting support portion 12. The two fitting recesses 38 are recessed in the insertion/removal direction (Z-axis direction) and penetrate therethrough, and are configured to receive fitting projections 32 of the second connector 20, which will be described later, so as to be fitted thereto. Thus, the first connector 10 is commonly referred to as a female connector.
The first mounting support portion 12 has a concave first terminal housing portion 13, and the first connection terminal 14 is supported by mounting the first connection terminal 14 in the first terminal housing portion 13. The plurality of first connection terminals 14 are arranged at substantially the center in the longitudinal direction (X-axis direction) of the first connector 10, and are aligned along the longitudinal direction (X-axis direction). In the first connection terminals 14 shown in fig. 2, three are arranged in 1 line along the longitudinal direction (X-axis direction). The arrangement of the multipolar first connection terminals 14 is not limited to 1 column, but may be 2 columns or 3 columns or more. The number of the first connection terminals 14 per 1 column is not limited to three, and may be two or less or four or more. In order to suppress electromagnetic wave interference between the rows of the first connection terminals 14, a conductive shielding member (not shown) may be provided between the rows of the first connection terminals 14.
The first connection terminal 14 extends in the longitudinal direction (Y-axis direction) as a whole as viewed in the insertion/extraction direction (Z-axis direction). The first connection terminal 14 is a conductor connected to a signal potential or a ground potential, for example, and is formed by bending a rod-shaped member having conductivity using a die. As the first connection terminal 14, a material having conductivity and capable of elastic deformation, for example, phosphor bronze can be used. Gold plating or the like may be applied to the surface of the first connection terminal 14, for example. The details of the first connection terminal 14 will be described later.
The first external ground member 36 is a conductor having a rectangular annular shape as viewed in the insertion/extraction direction (Z-axis direction) and connected to the ground potential. The first outer ground member 36 extends at the fitting surface portion and the outer side portion of the first insulating member 11. The first external ground member 36 is connected to the ground potential, thereby shielding unwanted radiation noise radiated from the inside and outside of the first connector 10. This can suppress leakage of noise generated from the first connection terminal 14 surrounded by the first external ground member 36 to the outside and entry of noise from the outside into the first connection terminal 14. That is, the first connection terminal 14 is electromagnetically shielded by being surrounded by the first external ground member 36. As the first external grounding member 36, a material having conductivity and capable of elastic deformation, for example, phosphor bronze can be used. The first external ground member 36 is formed by, for example, bending processing.
The first external grounding member 36 has guide portions 37 on both sides in the longitudinal direction (X-axis direction). The guide portion 37 has a substantially U-shape as viewed in the insertion/removal direction (Z-axis direction), and is inclined downward from the outside toward the inside. When the second connector 20 is inserted into the first connector 10 in the insertion/extraction direction (Z-axis direction), the guide 37 is used as a guide for accurately guiding the fitting convex portion 32 to the fitting concave portion 38.
[ second connector ]
Fig. 3 is a perspective view of the second connector 20 constituting the electrical connector assembly 1 shown in fig. 1.
As shown in fig. 3, the second connector 20 has a second insulating member 21, a plurality of second connection terminals 24, and two second external ground members 33. As the second insulating member 21, for example, an electrically insulating resin such as a liquid crystal polymer is used. The second insulating member 21 has a second mounting support portion 22 and two fitting convex portions 32. The second mounting support portion 22 is located at the substantially center in the longitudinal direction (X-axis direction) of the second connector 20, and the two fitting protrusions 32 are disposed at both end portions in the longitudinal direction (X-axis direction) of the second connector 20 separately. The fitting convex portion 32 is configured to protrude in the insertion and removal direction (positive direction in the Z-axis direction) and has a step, and is fitted to be inserted into the fitting concave portion 38 of the first connector 10. Thus, the second connector 20 is commonly referred to as a male-type connector.
The second mounting support portion 22 has a concave second terminal accommodating portion 23. The second connection terminal 24 is supported by mounting the second connection terminal 24 to the second terminal housing portion 23. The second external grounding member 33 is mounted and supported on the fitting convex portion 32.
The plurality of second connection terminals 24 are arranged at substantially the center in the longitudinal direction (X-axis direction) of the second connector 20, and are aligned along the longitudinal direction (X-axis direction). In the second connection terminals 24 shown in fig. 3, three are arranged in 1 row along the longitudinal direction (X-axis direction) corresponding to the first connection terminals 14. In order to suppress electromagnetic wave interference between the columns of the second connection terminals 24, a conductive shielding member (not shown) may be provided between the columns of the second connection terminals 24. An electrical connection is made between the second connection terminals 24 and the corresponding first connection terminals 14 by elastic contact.
The second connection terminal 24 extends in the Y-axis direction as a whole, as viewed in the insertion and extraction direction (Z-axis direction). The second connection terminal 24 is, for example, a conductor connected to a signal potential or a ground potential, and is formed by bending a rod-shaped member having conductivity using a die. As the second connection terminal 24, a material having conductivity and capable of elastic deformation, for example, phosphor bronze can be used. Gold plating or the like may be applied to the surface of the second connection terminal 24, for example. When the second connector 20 is fitted to the first connector 10, the second connection terminal 24 faces the first connection terminal 14. The second connection terminal 24 will be described in detail later.
The second external grounding members 33, 33 of one side and the other side are disposed on both sides in the longitudinal direction (X-axis direction) with the plurality of second connectors 20 interposed therebetween. The second external grounding member 33 is a conductor that is rectangular in shape as viewed from the insertion/extraction direction (Z-axis direction) and is connected to the ground potential. The second external grounding member 33 extends at the fitting surface portion and the outer side portion of the fitting protrusion 32. The second external ground members 33 and 33 of the one and the other are connected to the ground potential, thereby shielding unnecessary radiation noise from the longitudinal direction (X-axis direction) emitted from the inside and outside of the second connector 20. The second external ground members 33 and 33 of the one and the other cooperate with the first external ground member 36 to surround the second connection terminal 24, and the second connection terminal 24 is electromagnetically shielded by the second external ground member 33 and the first external ground member 36 of the one and the other. As the second external grounding member 33, a material having conductivity and capable of elastic deformation, for example, phosphor bronze can be used. The second external ground member 33 is formed by, for example, bending processing.
The first connector 10 and the second connector 20 are fitted by inserting the fitting convex portion 32 of the second connector 20 into the fitting concave portion 38 of the first connector 10. In the fitting of the connector, the second external grounding members 33, 33 are fitted with the first external grounding member 36, and the first external grounding member 36 and the second external grounding member 33 surround the first connection terminal 14 and the second connection terminal 24. Thus, the first and second external ground members 36 and 33 function as fitting portions, and the first and second connection terminals 14 and 24 are electromagnetically shielded. Thus, the fitting force between the first external ground member 36 and the second external ground member 33 can be increased, and the contact force between the first connection terminal 14 and the second connection terminal 24 can be increased.
[ first connection terminal and second connection terminal according to the first embodiment ]
The detailed structures of the first connection terminal 14 and the second connection terminal 24 according to the first embodiment will be described with reference to fig. 4 and 5. Fig. 4 is a sectional view illustrating a state in which the electrical connector assembly 1 (a section taken along the line IV-IV in fig. 1) is mounted on the circuit board 2. Fig. 5 is a diagram illustrating connection between the first connection terminal 14 and the second connection terminal 24 in the electrical connector assembly 1 according to the first embodiment. Before connection, (A) and (B) represent connection.
Fig. 4 shows a state in which the electrical connector assembly 1 is mounted on the circuit board 2. The circuit board 2 includes a first circuit board 3 and a second circuit board 4, and for example, a first connector 10 is mounted on the first circuit board 3 and a second connector 20 is mounted on the second circuit board 4.
As shown in fig. 5 (a), the first connection terminal 14 has a first contact portion 15, a first support portion 17, a first protruding portion 18, and a first mounting portion 19 extending in the Y-axis direction from the distal end side toward the proximal end side.
The first mounting portion 19 is located on the base end side and is supported by the first mounting support portion 12. The first mounting portion 19 is mounted and electrically connected to the first mounting connection portion 3a of the first circuit board 3 by a conductive member such as a solder bump. The first protruding portion 18 is located beside the distal end side with respect to the first mounting portion 19. The first protruding portion 18 protrudes in an inverted U-shape in the insertion/removal direction (Z-axis direction) toward the second connection terminal 24. The first protrusion facing surface 18a of the first protrusion 18 is a flat surface facing the second connection terminal 24 and extending parallel to the first mounting surface 3 b. Thus, even if there is a slight positional shift between the first protruding portion 18 and the second contact portion 25, the electrical connection can be obtained more reliably.
The first support portion 17 is located beside the distal end side with respect to the first protruding portion 18, and is located between the first contact portion 15 and the first protruding portion 18. When the first connector 10 is mounted on the first circuit board 3, each of the board facing surfaces of the first mounting portion 19 and the first supporting portion 17 is a surface facing the first circuit board 3 and is coplanar with the first mounting surface 3 b. The first contact portion 15 is located beside the distal end side with respect to the first supporting portion 17. The first contact portion 15 is a free end portion having elasticity by being supported by the first support portion 17. The first contact portion 15 extends and protrudes obliquely toward the second connection terminal 24 and toward the tip side. The first contact portion 15 extends, for example, at an angle of 30 degrees to 60 degrees inclined with respect to the first mounting surface 3 b. The first contact portion 15 is located beside the distal end side with respect to the first contact portion 15. The first contact portion 15 has a first contact surface 15a that is bent by protruding in an inverted U shape toward the second connection terminal 24.
The second connection terminal 24 has a second contact portion 25, a second support portion 27, a second protruding portion 28, and a second mounting portion 29 extending in the Y-axis direction from the distal end side toward the proximal end side.
The second mounting portion 29 is located on the base end side and is supported by the second mounting support portion 22. The second mounting portion 29 is mounted and electrically connected to the second mounting connection portion 4a of the second circuit board 4 by a conductive member such as a solder bump. The second protruding portion 28 is located beside the distal end side with respect to the second mounting portion 29. The second protruding portion 28 protrudes in a U-shape in the insertion/removal direction (Z-axis direction) toward the first connection terminal 14. The second protrusion facing surface 28a of the second protrusion 28 is a flat surface facing the first connection terminal 14 and extending parallel to the second mounting surface 4 b. Thus, even if there is a slight positional shift between the second protruding portion 28 and the first contact portion 15, the electrical connection can be obtained more reliably. In addition, in order to prevent a decrease in visibility of solder when mounted by being located in the vicinity of the first external ground member 36, the length of the first mounting portion 19 in the Y-axis direction is configured to be longer than the length of the second mounting portion 29 in the Y-axis direction.
The second support portion 27 is located beside the distal end side with respect to the second protruding portion 28, and is located between the second protruding portion 28 and the second contact portion 25. When the second connector 20 is mounted on the second circuit board 4, the board facing surfaces of the second mounting portion 29 and the second supporting portion 27 face the second circuit board 4 and are coplanar with the second mounting surface 4 b. The second contact portion 25 is located beside the distal end side with respect to the second support portion 27. The second contact portion 25 is a free end portion having elasticity by being supported by the second support portion 27. The second contact portion 25 extends obliquely toward the first connection terminal 14 and toward the distal end side and protrudes. The second contact portion 25 extends, for example, at an angle of 30 degrees to 60 degrees inclined with respect to the second mounting surface 4 b. The second contact portion 25 has a second contact surface 25a that is bent by protruding in a U-shape toward the first connection terminal 14.
The first contact portion 15, the first support portion 17, and the first protruding portion 18 of the first connection terminal 14 are formed in the same shape as the second contact portion 25, the second support portion 27, and the second protruding portion 28 of the second connection terminal 24, respectively. This allows the molds to be shared when the first connection terminal 14 and the second connection terminal 24 are processed, and therefore, the processing cost can be reduced, and the management of the molds becomes easy.
When the first connector 10 is mounted on the first circuit board 3, the first support portion 17 is configured to abut against and be supported by the first mounting surface 3b of the first circuit board 3. The first contact portion 15 is supported by the first support portion 17 with the cantilever Liang Fangshi, and thus functions as a free end portion having elasticity. At the time of connection of fig. 5 (B), the contact pressure of the first contact portion 15 acts on the pressing direction F, whereby the curved first contact surface 15a of the first contact portion 15 elastically contacts the flat second protrusion opposing surface 28a of the second protrusion portion 28. The direction of the contact pressure at this time, that is, the pressing direction F in which the first contact portion 15 presses the second connection terminal 24 at the time of fitting, is along the insertion/extraction direction (Z-axis direction). As a result, the first height h1b of the first contact portion 15 in the insertion/extraction direction (Z-axis direction) required to ensure a predetermined contact pressure becomes low, and therefore, the first connector 10 can be made low.
When the second connector 20 is mounted on the second circuit board 4, the second support portion 27 is configured to abut against and be supported by the second mounting surface 4b of the second circuit board 4. The second contact portion 25 is supported by the second support portion 27 with the cantilever Liang Fangshi, and thus functions as a free end portion having elasticity. At the time of connection of fig. 5 (B), the contact pressure of the second contact portion 25 acts on the pressing direction F, whereby the curved second contact surface 25a of the second contact portion 25 elastically contacts the flat first protrusion opposing surface 18a of the first protrusion 18. The direction of the contact pressure at this time, that is, the pressing direction F in which the second contact portion 25 presses the first connection terminal at the time of fitting, is along the insertion/extraction direction (Z-axis direction). Accordingly, the second height h2b of the second contact portion 25 in the insertion/extraction direction (Z-axis direction) required to ensure a predetermined contact pressure becomes low, and thus the second connector 20 can be made low.
Therefore, at the time of connection in fig. 5 (B), electrical connection based on elastic contact between the first contact portion 15 and the second protruding portion 28 and electrical connection based on elastic contact between the second contact portion 25 and the first protruding portion 18 can be obtained. That is, since two electrical connections are provided between the pair of first connection terminals 14 and the second connection terminal 24 by elastic contact, the reliability of the electrical connection is improved. The pressing directions F of the first contact portion 15 and the second contact portion 25 are along the insertion/extraction direction (Z-axis direction). As a result, the first height h1b and the second height h2b in the insertion/extraction direction (Z-axis direction) required for securing a predetermined contact pressure become low, and thus the electrical connector assembly 1 can be made low. The first connection terminal 14 and the second connection terminal 24 are electrically connected in the insertion/extraction direction (Z-axis direction), and are not connected to each other in the insertion/extraction direction (Z-axis direction). In other words, the first connection terminal 14 and the second connection terminal 24 are only in contact with the corresponding second contact portion 25 and first contact portion 15, respectively, and are not fitted to each other. That is, when the first connection terminal 14 and the second connection terminal 24 are to be separated in the insertion/extraction direction (Z-axis direction), a force for restricting the separation is not applied to the first connection terminal 14 and the second connection terminal 24. Further, the first embodiment (shown in fig. 5) in which the first contact portion 15 is in contact with the second protruding portion 28 and the second contact portion 25 is in contact with the first protruding portion 18 can be made lower than the third embodiment (shown in fig. 7) described later.
The first connection terminal 14 has: a first support portion 17 extending in a plane direction perpendicular to the thickness direction of the first insulating member 11; a first protruding portion 18 connected to one end of the first supporting portion 17 and protruding from the first supporting portion 17 in the thickness direction; and a first contact portion 15 connected to the other end of the first support portion 17, protruding from the first support portion 17 in the thickness direction and having a lower protruding height in the thickness direction than the first protruding portion 18. The second connection terminal 24 has: a second support portion 27 extending in a plane direction perpendicular to the thickness direction of the second insulating member 21; a second protruding portion 28 connected to one end of the second supporting portion 27 and protruding from the second supporting portion 27 in the thickness direction; and a second contact portion 25 connected to the other end of the second support portion 27, protruding from the second support portion 27 in the thickness direction, and having a lower protruding height in the thickness direction than the second protruding portion 28. Further, the first contact portion 15 is in contact with the second protruding portion 28, and the second contact portion 25 is in contact with the first protruding portion 18. Thereby, the electrical connector assembly 1 can be made low.
As shown in fig. 5 a, the first protruding height h1a of the first protruding portion 18 is set to be higher than the first height h1b of the first contact portion 15 with respect to the first mounting surface 3b before the first connection terminal 14 and the second connection terminal 24 are connected (i.e., in a non-fitted state). That is, the first contact portion 15 is recessed from the first protruding portion 18 in the insertion and extraction direction (Z-axis direction). This prevents the first contact portion 15 from being caught or deformed at the initial stage of fitting, that is, at the stage of introduction of the second connector 20.
Similarly, before the first connection terminal 14 and the second connection terminal 24 are connected (i.e., in a non-fitted state), the second protruding height h2a of the second protruding portion 28 is configured to be higher than the second height h2b of the second contact portion 25 with reference to the second mounting surface 4 b. That is, the second contact portion 25 is recessed from the second protruding portion 28 in the insertion and extraction direction (Z-axis direction). This prevents the second contact portion 25 from being caught or deformed at the initial stage of fitting, that is, at the stage of introduction of the second connector 20.
[ first connection terminal and second connection terminal according to the second embodiment ]
The detailed structures of the first connection terminal 14 and the second connection terminal 24 according to the second embodiment will be described with reference to fig. 6. Fig. 6 is a diagram illustrating connection between the first connection terminal 14 and the second connection terminal 24 in the electrical connector assembly 1 according to the second embodiment. Before connection, (A) and (B) represent connection.
In the first embodiment described above, the second connection terminal 24 has the second protruding portion 28 and the second contact portion 25, and the first contact portion 15 and the first protruding portion 18 of the first connection terminal 14 elastically contact the second protruding portion 28 and the second contact portion 25 of the second connection terminal 24, respectively. In contrast, in the second embodiment, the second connection terminal 24 does not have the second contact portion 25. As shown in fig. 6 (B), the contact pressure of the first contact portion 15 acts in the pressing direction F, whereby the first contact surface 15a of the first contact portion 15 elastically contacts the second protrusion opposing surface 28a of the second protrusion 28.
Thus, electrical connection by elastic contact between the first contact portion 15 and the second protruding portion 28 can be obtained, the man-hour for processing the second connection terminal 24 can be reduced, and the manufacturing cost of the electrical connector assembly 1 can be reduced.
[ first connection terminal and second connection terminal according to the third embodiment ]
The detailed structures of the first connection terminal 14 and the second connection terminal 24 according to the third embodiment will be described with reference to fig. 7. Fig. 7 is a diagram illustrating connection between the first connection terminal 14 and the second connection terminal 24 in the electrical connector assembly 1 according to the third embodiment. Before connection, (A) and (B) represent connection.
In the first embodiment described above, the first connection terminal 14 has the first supporting portion 17 and the first protruding portion 18, and the second connection terminal 24 has the second supporting portion 27 and the second protruding portion 28, and the first contact portion 15 and the first protruding portion 18 of the first connection terminal 14 elastically contact the second protruding portion 28 and the second contact portion 25 of the second connection terminal 24, respectively. In contrast, in the third embodiment, the first connection terminal 14 does not have the first supporting portion 17 and the first protruding portion 18, and the second connection terminal 24 does not have the second supporting portion 27 and the second protruding portion 28.
The first contact portion 15 extends obliquely and projects toward the second connection terminal 24 and toward the distal end side with the first mounting portion 19 as a base point. The first contact portion 15 functions as a spring supported by the first mounting portion 19 with a cantilever Liang Fangshi. The second contact portion 25 extends obliquely toward the first connection terminal 14 and toward the distal end side with the second mounting portion 29 as a base point. The second contact portion 25 functions as a spring supported by the second mounting portion 29 with a cantilever Liang Fangshi.
The first connection terminal 14 has: the first mounting portion 19 functions as a first portion extending in a planar direction perpendicular to the thickness direction of the first insulating member 11; and a first contact portion 15 serving as a second portion connected to one end of the first mounting portion 19 and protruding from the first mounting portion 19 in the thickness direction. The second connector 20 has: the second insulating member 21 has a fitting convex portion 32 fitted with the fitting concave portion 38; and a second connection terminal 24 held by the second insulating member 21. The second connection terminal 24 has: the second mounting portion 29 functions as a third portion extending in a plane direction perpendicular to the thickness direction of the second insulating member 21; and a second contact portion 25 serving as a fourth portion connected to one end of the second mounting portion 29 and protruding from the second mounting portion 28 in the thickness direction. The first mounting portion 19 as the first portion is in contact with the second contact portion 25 as the fourth portion, and the first contact portion 15 as the second portion is in contact with the second mounting portion 29 as the third portion. Thereby, the electrical connector assembly 1 can be made low.
The first mounting opposing surface 19a of the first mounting portion 19 and the second mounting opposing surface 29a of the second mounting portion 29 are flat surfaces extending parallel to the first mounting surface 3b and the second mounting surface 4b, respectively. Thus, even if there is a slight positional shift between the second mounting portion 29 and the first contact portion 15 or between the first mounting portion 19 and the second contact portion 25, the electrical connection can be obtained more reliably.
As shown in fig. 7 (B), the contact pressure of the first contact portion 15 acts in the pressing direction F, and thereby the first contact surface 15a of the first contact portion 15 elastically contacts the second mounting opposing surface 29a of the second mounting portion 29. At the same time, the contact pressure of the second contact portion 25 acts on the pressing direction F, whereby the second contact surface 25a of the second contact portion 25 elastically contacts the first mounting opposing surface 19a of the first mounting portion 19.
Thus, the electrical connection by elastic contact between the first contact portion 15 and the second mounting portion 29 and the electrical connection by elastic contact between the second contact portion 25 and the first mounting portion 19 can be obtained, the man-hours for processing the first connection terminal 14 and the second connection terminal 24 can be reduced, and the manufacturing cost of the electrical connector assembly 1 can be reduced.

The detailed configuration of the first connection terminal 14 and the second connection terminal 24 according to the fourth embodiment will be described with reference to fig. 8. Fig. 8 is a diagram illustrating connection between the first connection terminal 14 and the second connection terminal 24 in the electrical connector assembly 1 according to the fourth embodiment. Before connection, (A) and (B) represent connection.
In the first embodiment described above, the first connection terminal 14 and the second connection terminal 24 have the first supporting portion 17 and the second supporting portion 27, respectively, and the first protruding portion 18 and the second protruding portion 28 protrude in an inverted U-shape and a U-shape, respectively. In contrast, in the fourth embodiment, the first connection terminal 14 and the second connection terminal 24 do not have the first supporting portion 17 and the second supporting portion 27, respectively, the first protruding portion 18 protrudes in an L-shape with the first mounting portion 19 as a base point, and the second protruding portion 28 protrudes in an L-shape with the second mounting portion 29 as a base point.
The first connection terminal 14 has: the first protruding portion 18 functions as a first portion extending in a planar direction perpendicular to the thickness direction of the first insulating member 11; and a first contact portion 15 serving as a second portion connected to one end of the first protruding portion 18 and protruding from the first protruding portion 18 in the thickness direction. The second connector 20 has: the second insulating member 21 has a fitting convex portion 32 fitted with the fitting concave portion 38; and a second connection terminal 24 held by the second insulating member 21. The second connection terminal 24 has: the second protruding portion 28 functions as a third portion extending in a plane direction perpendicular to the thickness direction of the second insulating member 21; and a second contact portion 25 serving as a fourth portion connected to one end of the second protruding portion 28 and protruding from the second protruding portion 28 in the thickness direction. The first protruding portion 18 as the first portion is in contact with the second contact portion 25 as the fourth portion, and the first contact portion 15 as the second portion is in contact with the second protruding portion 28 as the third portion. Thereby, the electrical connector assembly 1 can be made low.
The first projection opposing surface 18a of the first projection 18 and the second projection opposing surface 28a of the second projection 28 are flat surfaces extending parallel to the first mounting surface 3b and the second mounting surface 4b, respectively. Thus, even if there is a slight positional shift between the second protruding portion 28 and the first contact portion 15, and between the first protruding portion 18 and the second contact portion 25, the electrical connection can be obtained more reliably.
As shown in fig. 8 (B), the contact pressure of the first contact portion 15 acts in the pressing direction F, whereby the first contact surface 15a of the first contact portion 15 elastically contacts the second protrusion opposing surface 28a of the second protrusion 28. At the same time, the contact pressure of the second contact portion 25 acts on the pressing direction F, whereby the second contact surface 25a of the second contact portion 25 elastically contacts the first protrusion opposing surface 18a of the first protrusion 18.
Thus, the electrical connection by elastic contact between the first contact portion 15 and the second protruding portion 28 and the electrical connection by elastic contact between the second contact portion 25 and the first protruding portion 18 can be obtained, the man-hours for processing the first connection terminal 14 and the second connection terminal 24 can be reduced, and the manufacturing cost of the electrical connector assembly 1 can be reduced.
