Description
[ field of technology ]

After the end connector and the board end connector are in butt joint, the lock hook of the elastic piece is clamped in the lock hole of the board end shell.
In the above connector assembly, the board end housing is flared with respect to the socket, so that a socket is formed between the board end housing and the socket to accommodate the first board, and when the line end connector is subjected to a hanging pull force (for example, the line end connector is pulled down by the gravity of the line due to the sagging of the line), the line end connector can be limited in the socket through the first board, thereby resisting the hanging pull force and avoiding the line end connector and the board end connector from being separated from each other. However, the latch hook and the latch hole are exposed outside the first plugboard and are easy to damage to affect subsequent use.

In this embodiment, the accommodating portion 14 is formed by a part of the first body and a part of the second body, and has four insulating walls and includes a space surrounded by the four insulating walls.
Referring to fig. 1, 3 and 4, the first insulating body 1 has a joint portion 12, and the joint portion 12 and the extension portion 11 are located on two sides of the abutting portion 21 along the second direction Y, respectively. In this embodiment, the engaging portion 12 is in a groove shape and is located at a connection position between the limiting plate 13 and the accommodating portion 14. In other embodiments, the engagement portion 12 may be in other configurations, not limited herein. For example, the engaging portion 12 may be a local surface of a structure in the first insulating body 1 (for example, the engaging portion 12 may be a local part of an outer side surface of the limiting plate 13, and the first extension arm 76 is fastened to a certain position of the outer side surface of the limiting plate 13).
Referring to fig. 3, 5 and 9, the locking member 3 is fixed to the extension portion 11, the locking member 3 has two first locking portions 3121, the first locking portions 3121 are exposed on the inner side 111 of the extension portion 11, and the first locking portions 3121 are spaced from the abutting portion 21 by the first accommodating space G1.
Referring to fig. 4 to 6, when the first connector 100 and the second connector 200 are mated, the first terminal 23 and the second terminal 9 are mated, and the first wall 71 and the second wall 72 are located on both sides of the mating portion 21 along the second direction Y. In addition, the first connector 100 and the second connector 200 of the present embodiment may be plugged in the opposite directions, if the first connector 100 and the second connector 200 are plugged in the opposite directions, the first wall 71 is received in the first receiving space G1 after the mating is completed, the mating portion 21 is received in the receiving cavity 65, the outer surface of the first wall 71 faces the inner side 111 of the extension portion 11, the first locking portion 3121 is locked with the second locking portion 75 of the first wall 71, and the first extension arm 76 is locked with the joint portion 12. If the first connector 100 and the second connector 200 are plugged in opposite directions, the second wall 72 is received in the first receiving space G1 after the mating is completed, the mating portion 21 is received in the receiving cavity 65, the outer surface of the second wall 72 faces the inner side 111 of the extension portion 11, the first locking portion 3121 and the second locking portion 75 of the second wall 72 are locked with each other, and the second extension arm 77 and the joint portion 12 are locked with each other. That is, in the present embodiment, the second connector 200 has the second locking portions 75 on opposite sides in the second direction Y, and the first locking portions 3121 can be locked with the second locking portions 75 on either side.
The first locking part 3121 and the second locking part 75 of the present application are locked with each other between the inner side 111 of the extension part 11 and the abutting part 21, the first wall 71 of the metal shell 7 does not need to be expanded to the outer side 112 of the extension part 11 to be locked with the outer side first locking part 3121, and the first locking part 3121 and the second locking part 75 are not exposed to the outer side 112 of the extension part 11, so that the first locking part 3121 and the second locking part 75 can be prevented from being damaged by the collision deformation; since the first wall 71 does not extend to the outer side 112 of the extension 11 to cover the extension 11, and the extension 11 cannot be limited between the first wall 71 and the second insulating body 6, the present application further increases the connection stability between the first connector 100 and the second connector 200 through the mutual fastening between the first extension arm 76 and the joint 12, especially when the first connector 100 is under a hanging heavy tension, the risk that the first extension arm 76 and the joint 12 are mutually fastened and then separated from the second connector 200 after the first connector 100 is under a hanging heavy tension is reduced. In addition, since the engaging portion 12 and the extending portion 11 are respectively located at both sides of the abutting portion 21, when the first connector 100 receives the hanging force in either side of the second direction Y, the engaging portion 11 limits the outer side of the first wall 71 and the engaging portion 12 and the first extending arm 76 to resist the hanging force, so that the risk that the first connector 100 and the second connector 200 are separated from each other can be reduced more effectively.
Further, in the present application, since the first locking portion 3121 and the second locking portion 75 are locked between the inner side 111 of the extension portion 11 and the abutting portion 21, the inner surface of the first wall 71 and the inner surface of the second wall 72 can be respectively adjacent to and cover the first side 61 and the second side 62, without the need of expanding the first wall 71 or the second wall 72 with respect to the first side 61 and the second side 62 to form an accommodating space for accommodating the extension portion 11, the molding material increased by the expansion of the metal shell 7 is reduced, and the present application can realize the locking of the first locking portion 3121 and the second locking portion 75 of the first wall 71, or the locking of the first locking portion 3121 and the second locking portion 75 of the second wall 72, and can realize the positive and negative insertion of the first connector 100 and the second connector 200.
It should be noted that, in other embodiments, the first connector 100 and the second connector 200 may not implement the forward plug, and may only satisfy the forward plug, and the technical solution of the present application is not limited to be used in the forward plug technical solution. It will be appreciated that the two side structures of the second connector 200 need not be arranged symmetrically, the second wall 72 may not be provided with the second locking portion 75, and the metal shell 7 may only retain the first extension arm 76 and not the second extension arm 77.
Referring to fig. 5 and 9, the first insulating body 1 has a mating surface 18 facing the second connector 200 along the first direction Z, the mating portion 21 extends beyond the mating surface 18 along the first direction Z, the engaging portion 12 is close to an end of the mating portion 21 with respect to the mating surface 18 along the first direction Z, and an end of the mating portion 21 extends beyond the engaging portion 12 along the first direction Z, as projected along the third direction X. Correspondingly, as shown in fig. 2 and 3, the second insulating body 6 has a pair of mating end faces 66 facing the first connector 100 in the first direction Z. As shown in fig. 3 and 8, when the first connector 100 and the second connector 200 are mated, the first extension arm 76 and the second extension arm 77 are close to the end of the extension 11 along the first direction Z with respect to the mating end surface 66. If the first direction Z is referred to as the up-down direction, the first extension arm 76 and the second extension arm 77 are not higher than the abutting end surface 66 of the second insulating body 6. Thus, the engaging portion 12 of the present embodiment is not located outside the second insulating body along the first direction (if the first direction Z is referred to as the up-down direction, the engaging portion 12 is not located above the second insulating body along the first direction Z), so that the position between the first extension arm 76 and the engaging portion 12 can be located further away from the first connector 100 and closer to the second connector 200, i.e. closer to the position where the first connector 100 and the second connector 200 are combined, and the difficulty of disengaging between the second connector 200 and the engaging portion 12 when the first connector 100 is under the hanging heavy tension is increased.
In addition, as shown in fig. 2 and 3, the first extension arm 76 is torn and punched from the second wall 72, the root of the first extension arm 76 is connected to the third wall 73, and similarly, the second extension arm 77 is torn and punched from the first wall 71, and the root of the second extension arm 77 is connected to the third wall 73. Since the first extension arm 76 extends along the second direction Y, when the first extension arm 76 is subjected to the force of the second direction Y, assuming that the first extension arm 76 tears from the second wall 72 and is only connected to the second wall 72 and is not connected to the third wall 73, the first extension arm 76 may continue to pull the second wall 72 to tear further after being subjected to the force, resulting in damage to the metal shell 7, while the first extension arm 76 of the present application tears from the second wall 72 and the root is connected to the third wall 73, since the plane of the third wall 73 is parallel to the second direction Y, the third wall 73 is not easily torn when the first extension arm 76 is subjected to the force of the second direction Y, thereby reducing the risk of damage to the metal shell 7. Similarly, the root of the second extension arm 77 is connected to the third wall 73, so as to avoid tearing the metal shell 7 when the second extension arm 77 is stressed.
Referring to fig. 2 and 3, a first end and a second end of the first wall 71 opposite to each other along the third direction X are respectively connected to the third wall 73 and the fourth wall 74, and a first positioning portion 711 is disposed at the first end of the first wall 71. The first end and the second end of the second wall 72, which are disposed opposite to each other along the third direction X, are respectively connected to the third wall 73 and the fourth wall 74, and the first end of the second wall 72 is provided with a second positioning portion 721. The third wall 73 has a third positioning portion 731, and the first positioning portion 711, the second positioning portion 721, and the third positioning portion 731 are all configured to be fixedly connected to a second electronic component; the metal shell 7 has a fixing portion 79 connected to the third wall 73, and the fixing portion 79 is fixed to the second insulating body 6. The connection stability of the third wall 73 and the second electronic component can be integrally increased by the first positioning part 711, the second positioning part 721, the third positioning part 731, and the fixing part 79, and when the first connector 100 receives a hanging weight pulling force, the stability of the first extension arm 76 can be increased because the first extension arm 76 is connected with the third wall 73, effectively enhancing the connection stability between the first connector 100 and the second connector 200.
Similarly, when the metal shell 7 further has another first extension arm 76 connected to the fourth wall 74, a fourth positioning portion 712 is disposed at the second end of the first wall 71, a fifth positioning portion 722 is disposed at the second end of the second wall 72, the fourth wall 74 has a sixth positioning portion 741, and the fourth positioning portion 712, the fifth positioning portion 722 and the sixth positioning portion 741 are all fixedly connected to the second electronic element; the metal shell 7 has a fixing portion 79 connected to the fourth wall 74, and the fixing portion 79 is fixed to the second insulating body 6. The same may be able to increase the stability of the other of the first extension arms 76, effectively enhancing the connection stability between the first connector 100 and the second connector 200.
Referring to fig. 5 and 6, the second accommodating space G2 accommodates at least a portion of the second connector 200, and the inner side of the limiting plate 13 and the inner side 111 of the extending portion 11 are used to limit the movement of the second connector 200 along the second direction Y. Thus, when the first connector 100 is subjected to the sling force at a position adjacent to the limiting plate 13, even if the first connector 100 is driven by the sling force to be separated from the second connector 200, the present application can limit the relative movement between the first connector 100 and the second connector 200 by the limiting plate 13 and the extension portion 11, so as to further reduce the risk of separation from the second connector 200 when the first connector 100 is subjected to the sling force.
Referring to fig. 2 and 3, the metal shell 7 is formed with the first wall 71, the second wall 72, the third wall 73 and the fourth wall 74 by a single piece of material, and the metal shell 7 has a joint 78, and the joint 78 is close to the third wall 73 or the fourth wall 74 along the third direction X with respect to the two second locking portions 75. Compared with the combination portion 78 being located between the two second locking portions 75, the material separation at two sides of the combination portion 78 is easily driven by the stress deviation of the two second locking portions 75, but the combination portion 78 of the present application is not located between the two second locking portions 75, so that the coplanarity of the two second locking portions 75 of the first wall 71 can be increased, and the material separation at two sides of the combination portion 12 caused by the stress deviation when the two second locking portions 75 are locked can be prevented.
Referring to fig. 1, 8 and 9, the engaging portion 12 is in a groove shape and is located at a connection position between the limiting plate 13 and the accommodating portion 14, the limiting plate 13 extends beyond the accommodating portion 14 along the first direction Z, and when the first connector 100 and the second connector 200 are mated and the first wall 71 enters the first accommodating space, the first extension arm 76 at least partially enters the engaging portion 12. Thus, after the first extension arm 76 enters the engaging portion 12, the limiting plate 13 and the accommodating portion 14 limit the movement range of the first extension arm 76, so as to help the second connector 200 more accurately mate with the first connector 100; moreover, the joint portion 12 is disposed at a connection position between the limiting plate 13 and the accommodating portion 14, so that the extension length of the first extension arm 76 is moderate, which can avoid the first extension arm 76 from being too short to collide with the limiting plate 13 during the abutting process, and can make the end of the first extension arm 76 approach the abutting portion 21 as much as possible, so as to reduce the material used for the first extension arm 76.
Referring to fig. 5 and 6, when the first connector 100 and the second connector 200 are mated, the projection of the accommodating portion 14 overlaps the projection of the first wall 71 and the projection of the second wall 72 when viewed along the second direction Y. Thus, with respect to the projection of the accommodating portion 14, the first wall 71 and the second wall 72 being staggered, the accommodating portion 14 of the present application can be relatively close to the second connector 200 along the first direction Z, and the connection position of the first electronic component 300 can be relatively sunk, which is beneficial to reducing the size of the first connector 100 in the first direction Z.
Referring to fig. 8 and 10, in the present embodiment, the first extension arm 76 or the second extension arm 77 is fastened to the joint 12. Defining a third direction X perpendicular to the first direction Z and the second direction Y, and when the first connector 100 and the second connector 200 are mated, the projection of the first extension arm 76 or the second extension arm 77 is located within the projection of the extension 11 when viewed along the third direction X. That is, as viewed in the third direction X, a distance between the engaging portion 12 and the abutting portion 21 in the second direction Y is defined as a first distance D1, a distance between the outer side 112 of the extending portion 11 and the abutting portion 21 in the second direction Y is defined as a second distance D2, and the first distance D1 is not greater than the second distance D2. Thus, the first extension arm 76 or the second extension arm 77 can resist the hanging pulling force when the first connector 100 and the second connector 200 are connected in a forward-reverse manner; meanwhile, when the first extension arm 76 and the joint portion 12 are fastened, the second extension arm 77 does not extend beyond the outer side 112 of the extension portion 11, and when the second extension arm 77 and the joint portion 12 are fastened, the first extension arm 76 does not extend beyond the outer side 112 of the extension portion 11, so that the arrangement of the first extension arm 76 and the second extension arm 77 can be prevented from increasing the overall dimension of the first connector 100 and the second connector 200 in the second direction Y after the mating is completed.
In this embodiment, the extending portion 11 needs to maintain a certain thickness for positioning the locking member 3, the limiting plate 13 does not need to fix the locking member 3, so the thickness of the limiting plate 13 may be smaller than the thickness of the extending portion 11, and since the engaging portion 12 of the present application is not provided on the extending portion 11, the extending lengths of the first extending arm 76 and the second extending arm 77 are not affected by the thickness of the extending portion 11, for example, in this embodiment, the extending lengths of the first extending arm 76 and the second extending arm 77 only need to satisfy the thickness of the limiting plate 13, so the extending length ranges of the first extending arm 76 and the second extending arm 77 are more flexible.
Referring to fig. 11 and 12, the latch 3 further includes a latch body 31 and a force application portion 35 connected to the latch body 31, and the first latch portion 3121 is disposed on the latch body 31. In this embodiment, the latch body 31 has a flat plate portion 311 and two protruding portions 312. The two first locking portions 3121 are respectively located at the two protruding portions 312, and the urging portion 35 is located outside the extending portion 11. The locking piece 3 further includes two limiting portions 33, two elastic supporting arms 34, two fixing arms 32, and two supporting points 36, wherein the two limiting portions 33 are accommodated in the extending portion 11, the elastic supporting arms 34 extend toward the inner side 111 of the extending portion 11 and are abutted to the inner side 111 of the extending portion 11, the two fixing arms 32 are respectively located at two sides of the force applying portion 35 and are fixed to the extending portion 11, and the two supporting points 36 are abutted to the first insulating body 1.
In this embodiment, when the force application portion 35 is stressed, the latch 3 prys the first latch portion 3121 about the fulcrum 36 according to the lever principle, so that the first latch portion 3121 deforms in the second direction Y in a direction away from the abutting portion 21, the elastic supporting arm 34 is pressed toward the inner side 111 of the extension portion 11 and abuts against the inner side 111 of the extension portion 11, and the limiting portion 33 allows a certain range of movement in the second direction Y within the extension portion 11, limiting the deformation degree of the latch 3; when the force applied to the force applying portion 35 is reduced, the elastic supporting arm 34 provides a restoring force for restoring, so as to drive the first locking portion 3121 to gradually restore. The fixing arm 32 of the present embodiment is bent and extended from the flat plate portion 311 to form a U-shaped arm fastened and fixed on the extension portion 11. In other embodiments, the latch 3 is not necessarily provided with the elastic abutment arm 34 exclusively, but it is also possible to pass the restoring force by means of a U-shaped structure; the fixed arm 32 need not be a U-shaped arm, but may be other fixed structures; the limit part 33 may be set or removed according to actual needs.

The through hole 113 facilitates the observation of the relative positions of the first locking portion 3121 and the second locking portion 75, and the first locking portion 3121 is an opening through which it is possible to further observe whether the second locking portion 75 enters into or exits from the opening, so that it is convenient to determine whether the first locking portion 3121 and the second locking portion 75 are successfully locked or unlocked.
Referring to fig. 7, in the present embodiment, the first locking portion 3121 is an opening, an elastically deforming space G3 is provided between the first locking portion 3121 and the inner side 111 of the extension portion 11 for the first locking portion 3121 to move, and the first locking portion 3121 allows the second locking portion 75 to enter in a direction of the elastically deforming space G3. Therefore, compared to the second locking portion 75 being an opening for the first locking portion 3121 to enter, the present application requires providing a space for letting out the first locking portion 3121 in the second connector 200, and the present application can simultaneously use the elastic deformation space G3 originally provided for deforming the locking member 3 to let out the second locking portion 75 without providing a space for letting out the first locking portion 3121 in the second connector 200 and without additionally providing a space for letting out the second locking portion 75 in the first connector 100.
Referring to fig. 1, 2 and 6, the first locking portion 3121 is an opening, the second locking portion 75 is a hook, the inner side of the limiting plate 13 is used for limiting the movement of the second connector 200 along the second direction Y, the limiting plate 13 has two yielding grooves 131 extending from the end thereof along the first direction Z, and the yielding grooves 131 are used for accommodating the second locking portion 75 of the first wall 71 or the second locking portion 75 of the second wall 72. Therefore, on the basis of realizing forward and reverse plugging of the first connector 100 and the second connector 200 and limiting the second connector 200 by the limiting plate 13, the second locking portion 75 of the first wall 71 or the second wall 72 is prevented from being scratched by the abdication groove 131, and a certain guiding function is achieved in the abutting process of the first connector 200 and the second connector 200.
In the present embodiment, the mating portion 21 of the first connector 100 is shaped like a tongue plate, and the second connector 200 is shaped like a slot; however, in other embodiments, the mating portion 21 may be slot-shaped, the second connector 200 may be provided with a tongue plate to mate with the mating portion 21, and the second insulating body 6 may still be provided with a receiving cavity 65 to receive the mating portion 21.
In this embodiment, the transmission member 2 is made of an insulating material and the first terminal 23 is formed by molding and injection molding, and in other embodiments, the transmission member 2 may be in other forms, which is not limited herein. For example, the transmission member 2 is an insulating material and the first terminal 23 are formed by assembly and insertion; or the transmission member 2 is a circuit board, and the first terminal 23 is formed by etching a metal plating material and is fixed on a base material of the circuit board; or the connection portion 232 of the first terminal 23 is a wire, and the contact portion 231 and the conductive portion 233 are connected by a wire.
In this embodiment, the abutting portion 21 of the transmission member 2 is of a separate structure from the first insulating body 1, in other embodiments, the abutting portion 21 may be integrally formed with the first insulating body 1, and no separate transmission member 2 may be provided, such as injection molding of the first terminal 23 and the insulating material, so that the first insulating body 1 and the abutting portion 21 are formed.
It should be noted that, the number of the first locking portions 3121, the through hole 113, the fixing arm 32, the elastic supporting arm 34, the supporting point 36, the limiting portion 33, and the yielding groove 131 is not limited to two in this embodiment, and the number of the second locking portions 75 on each side is not limited to two in this embodiment, and may be one or more than two according to actual needs.
In this embodiment, the engaging portion 12 is in a groove shape, and in other embodiments, the engaging portion 12 may be in other forms, for example, the engaging portion 12 may be a local surface of a certain structure in the first insulating body 1 (for example, the engaging portion 12 may be a local part of an outer side surface of the limiting plate 13, and the first extension arm 76 is fastened to a certain position of the outer side surface of the limiting plate 13). In the present embodiment, the metal shell 7 has two completely separated first extension arms 76 located on both sides in the third direction X, respectively; in other embodiments, two ends of a first extension arm 76 are respectively connected to two ends of the first wall 71, or two ends of a first extension arm 76 are respectively connected to the third wall 73 and the fourth wall 74, a cavity is formed between the first extension arm 76 and the second insulating body 6, the first extension arm 76 is fastened into a strip-shaped concave joint portion 12 of the accommodating portion 14 or fastened to an outer side surface of the limiting plate 13, and the cavity is used for accommodating a part of the material of the accommodating portion 14 or the limiting plate 13 after the first extension arm 76 is fastened to the joint portion 12. In addition, in other embodiments, it is also possible that the engaging portion 12 is hole-shaped, and the first extension arm 76 enters the engaging portion 12, however, other embodiments of the first extension arm 76 and the engaging portion 12 are possible other than the exemplary embodiment of the present application, and are not limited herein.

2. The engagement portion 12 is located closer to the end of the abutment portion 21 than the abutment surface 18 along the first direction Z, so that the position between the first extension arm 76 and the engagement portion 12 can be located farther from the first connector 100 and closer to the second connector 200, i.e. closer to the position where the first connector 100 and the second connector 200 are combined, increasing the difficulty of disengaging the second connector 200 from the engagement portion 12 when the first connector 100 is subjected to a hanging weight.
