の短縮と品質保持の面からも好ましくない。 Among so-called flat cables that are constructed by arranging multiple conductors inside a flexible insulator, those with a structure in which signal wires and ground wires are arranged alternately are especially used for signal transmission. be. In the connector that connects this signal transmission flat cable (hereinafter referred to as flat cable) to the equipment, each signal line is connected to each signal circuit of the equipment by an individual contact, but the grounding wire is first connected to the common Many of them have a structure in which they are connected all at once to a grounding plate, etc., and the grounding plate is further connected to the grounding circuit of the device through another contact. FIG. 1 is an enlarged view of the main parts of an example of a conventional flat cable connector, in which a signal contact 2 and a ground contact 3 are arranged in a housing 1 made of an insulator. The upper part protrudes from the upper surface of the housing 1 to form connection terminals 2a and 3a, and the lower part forms a pair of elastic contact pieces 4, which protrude into the terminal insertion hole formed in the lower surface of the housing 1, and connect to the connector on the device side. When the connector is mated with the connector, it is connected to a pin terminal (not shown) of the connector. The terminal insulation of the flat cable 5 to be connected is cut off to expose the signal line 6 and ground line 7. After cutting each wire to an appropriate length, the signal wire 6 is connected to the connection terminal 2a of each signal contactor 2 by soldering, but the ground wire 7 is folded back in the opposite direction and then connected to the ground plate 8. Solder all at once. The ground plate 8 has a substantially rectangular shape, and is provided with shorting legs 8a at both ends or one end thereof.
The tip of a is connected to the connection terminal 3a of the ground contact 3 by soldering as well. By fitting the connectors, each contact is connected to the pin terminal on the device side as described above, each signal wire 6 is connected to the signal circuit on the device side, and the ground wires 7 are connected all together to the same ground circuit. will be done. Note that the signal contact 2 and the ground contact 3 are usually of the same shape, and since the pitch between the respective wires is small, the contact pieces of adjacent contacts should not be too close together, for example, as shown in Figure 1. Sometimes a method of arranging them in opposite directions alternately is also used. In the above-mentioned conventional connector, the grounding contact for further connecting the grounding wires collectively connected to the grounding plate to the grounding circuit of the device depends on the shape of the grounding plate used, ie, the position or number of shorting legs. The location or number is determined by However, since the grounding circuit on the device side changes depending on the model or design change,
It is necessary to change the shape of the ground plate on the connector side each time, which increases the types of connectors or the number of parts that the manufacturer needs to prepare, hinders mass production, and increases the price as well as the user side. It is equally inconvenient. Furthermore, when assembling the flat cable and connector, the connections between each signal line, the ground line, and the shorting leg and contact terminal are all done by soldering. Because it is extremely small and the contacts of the connector are closely arranged, soldering work is difficult and there is a risk of accidentally damaging other parts during work, reducing work time and improving quality. It is also unfavorable from the viewpoint of retention.

ない。 An embodiment of the present invention will be described in detail below with reference to the drawings. 2 and 3 are partially cutaway and omitted perspective views of the flat cable connector 10 according to the present invention, and FIG. 2 shows the state before the cover 50 is coupled to the insulator assembly 20. The cable holder 60 is omitted.
FIG. 3 shows the connector 10 in a fully assembled state,
A flat cable 5 is connected, and an insulator assembly 20, a cover 50, and a cable holder 60 are coupled together. The insulator assembly 20 includes an insulator 21, a plurality of signal contactors 30,
One or more grounding contacts 31 and grounding plate 40
By approaching and pressing the cover 50 holding the end portion of the flat cable 5 with the conductor wires exposed from the upper surface of the insulator 21 (the upper part of the figure, the same applies hereinafter), each conductor wire is connected to each contactor 30.
and 31 and the ground plate 40, and the cover 50 is also coupled to the insulator assembly 20. After that, when the cable holder 60 is placed on the cover 50 from above and pressed, the cable holder 60 also covers the cover 50 and the insulator assembly 2.
0 and the flat cable connector 10 is assembled. Next, each part will be explained. First, the signal contact 30 has an external shape as shown in FIG. 4a, and FIG. 4b is a developed view thereof. The terminal 32 extends perpendicularly from the base portion 33, and is provided with a press-fit slot 34 and a press-fit guide portion 35 forming a tapered portion outwardly from the open end of the press-fit slot 34 on its center line. The width of the press-fit slot 34 is set to a value slightly smaller than the outer diameter of the signal line 6 of the flat cable to be connected. The signal contact 30 has a base portion 33 with a fourth
A frame-shaped portion is formed by bending at right angles to one side along each dotted line in FIG. Next, contact protrusions 36a are formed in the vicinity of the tips in a direction closer to each other, and then the tips are bent outward to separate from each other to form receiving ends 36b. The dimension e of the base portion 33 after bending in FIG. 4a is a dimension suitable for press-fitting into the insulator 21, which will be described later. Next, FIG. 5 shows an external view and a developed view of the grounding contact 31. Since the grounding contact 31 is similar to the signal contact 30 described above, the same functional parts of both are the same. They are indicated by symbols and their explanations are omitted. The terminal 32 including the slot 34 etc. in the grounding contactor 31, the base body part 33, and the contact piece 36 all have the same shape as the signal contactor 30, and the dimensions e of the base body part 33 are also the same. The difference is that a ground plate connecting portion 37 protrudes from the end of the portion 33 opposite to the terminal 32 in the same direction as the terminal 32. The connecting portion 37 is divided into two symmetrical pieces 37 by a slot 38 provided along the center line.
a, 37a, each outer edge 37b of the piece is inclined upwardly and inwardly to each other, and the upper part thereof has locking protrusions 37c, 37c that once project outwardly from each other.
After that, the beveled edges 37d extend inward toward each other and increase in height. The main connecting portion 37 has its slots 38 in the direction in which the width of the slots 38 becomes smaller when a force is applied to the outer edge 37b or the locking protrusion 37c in the direction of the center line of the slots. Distance f ₁ between the tips of the locking protrusions 37c in Figure b, or the locking protrusions 37c and the outer edge 37b
The step portions 37e and 37e can be elastically deformed so that the distance f ₂ between the step portions 37e and 37e becomes smaller. Next, the ground plate 40 is a substantially rectangular metal plate as shown in FIG. 6, and its total length in the longitudinal direction and width g in the direction perpendicular to the longitudinal direction match the dimensions of the upper surface of the insulator 21, which will be described later. . A plurality of terminal through holes 41 are formed through the surface of the ground plate 40, and each through hole has the same shape and is arranged in two rows. The through hole 41 has a long diameter part 41a and a short diameter part 41 as shown in FIG. 6d.
b, and the short diameter portion 4 of each row is approximately L-shaped.
1b are arranged so that they face in opposite directions. Here, the inner dimensions h and i of the major diameter portion 41a are the fourth
It is made sufficiently larger than the maximum width j and thickness k of the terminal 32 portion of the signal contactor 30 in Figure a. Further, the inner dimension l in the longitudinal direction of the short diameter portion 41b is slightly smaller than the dimension f ₂ of the ground plate connecting portion 37 of the ground contactor 31 in FIG. 4b. A plurality of projecting pieces 43 protrude from one side edge 42 in the longitudinal direction of the ground plate 40 on the same plane as the surface of the ground plate, and from the other side edge 44, FIG. 6 is a front view and a side view. As shown in b and c, a plurality of ground wire terminals 45 and 46 having the same shape are formed to protrude in a direction perpendicular to the surface of the ground plate. The terminals 45 and 46 are arranged in a staggered manner parallel to the side edge 44, with the terminal 45 on the side closer to the center line and the terminal 46 on the far side, and the arrangement pitch is determined by the grounding of the flat cable 5 to be connected. It matches the pitch of line 7. The pitch of the grounding wire 7 is the value shown by m in FIG. The shapes of the ground wire terminals 45 and 46 are almost the same as the terminals 32 of the signal contact 30, except that the press-fit slots 45a and 4
The width of 6a is slightly smaller than the diameter of ground wire 7. Note that the terminals 45 and 46 are arranged in a staggered manner in the press-fit slots 45a and 46a.
As described later, when the ground wire of the flat cable is press-fitted, the slot is elastically deformed to slightly expand, so that the side edges of each terminal do not come into contact with each other and interfere with the press-fitting operation. It's for a reason. Next, referring to Fig. 2, insulator 2
Reference numeral 1 denotes a substantially rectangular parallelepiped insulating block, which is provided with side walls 22 and 23 that are parallel to the longitudinal direction and extend upward from both opposing sides, and the portion of the insulator 21 between the two sides is flat. and forms the upper surface 24. Here the side walls 22 and 2
The internal dimensions between the three spaces are equal to the width g of the ground plate 40, and the total length of the upper surface 24 in the longitudinal direction is also equal to the total length of the ground plate 40.
can be mounted in a position overlapping the upper surface 24, and is held between the side walls 22 and 23 to such an extent that it cannot be easily removed. The side wall 22 has a vertical cut 22 between its upper edge 22a and the upper surface 24.
A plurality of b are formed. Also, the side wall 23 is the side wall 22
The height is slightly lower than that of the ground plate, and notches 23b are formed from the upper edge 23a to the upper surface 24, but the number and position of the notches 22b match those of the protruding piece 43 of the ground plate, and the notches 23b The number and position of the ground line terminals 45 match the number and position of the ground wire terminals 45 inside the ground plate 40. Next, a plurality of contact mounting holes 26 are penetrated between the upper surface 24 and the lower surface 25 of the insulator 21 for mounting the signal contact 30 and the grounding contact 31. Engagement protrusions 27a and 27b are protruded from both side surfaces 27 perpendicular to the connector for locking the cover 50 and cable holder 60 when assembling the connector. The cross-sectional shape of the upper part of the contact mounting hole 26 is equal to the cross-sectional contour of the base portion 33 of each of the contacts 30 and 31, but the portion having the dimension e in FIG. 4 or 5 a The dimensions corresponding to e are slightly smaller than e for press-fitting purposes. Further, from the middle of the mounting hole 26 downward, the dimension is slightly smaller than the cross-sectional profile of the base portion 33, and when the contact is inserted into that portion, the lower edge 33a of the base portion 33 comes into contact and its advancement is prevented. A step (not shown) for stopping is formed. Further, the cross-sectional dimension of the opening in the insulator lower surface 25 is further reduced to form a pin terminal insertion opening 26. The insertion opening 26a allows the mating pin terminal to be inserted into each contact 30 or 31 when the present connector 10 is connected to a device-side connector (not shown).
This is an introduction port for correctly fitting the contact pieces 36 between the contact pieces 36 of the contact pieces 36. Each of the contacts 30 and 31 is inserted into the mounting hole 26 from the insulator top surface 24 side with its contact piece 36 first. Since the size of each contact is slightly larger than that of the corresponding portion, each contact is inserted into the mounting hole 26 in a press-fit state, and because of the step portion, the contact is not inserted beyond a certain position and is stopped. As a result, each of the contacts 30 and 31 is sufficiently held at a fixed position within the mounting hole 26 without easily moving or slipping out. The contact mounting holes 26 are arranged in two rows in the longitudinal direction of the insulator 21, and are arranged in a staggered manner between each row, and the contacts inserted into the mounting holes are the same in the same row. The position is taken, but the direction is reversed between each row. That is, as shown in FIG. 2 or 3, the terminals 35 are located close to each other in each row. This is because the signal wire 6 of the flat cable 5 is connected to each signal contact 30, so the arrangement pitch of the terminal 32 portion (that is, the press-fit slot 34) of each signal contact is the same as the signal wire of the flat cable 5. 6 no pitch (2nd
(which is the same as m in the figure), and since the pitch m is a small value, by arranging the signal contacts 30 in two staggered rows as described above instead of in one row. In addition, the pitch of the press-fitting slot can be made to match the pitch of the signal line, and since the terminal portions are brought closer to each other, the entire connector can be made smaller. Next, as a contact for connecting the ground plate to the ground circuit of the device, the ground contact 31 shown in FIG. 5 is used (in place of the signal contact 30 shown in FIG. 4). Since the grounding contactor 31 has the same dimensions as the signal contactor and the base portion 33 except that the grounding plate connecting portion 37 is provided, it can be handled in the same way as the signal contactor 30, and the grounding The contact is inserted into a terminal insertion hole corresponding to a pin terminal connected to a ground circuit on the device side. After inserting each contactor 30 and 31, when the grounding plate 40 is placed over the insulator 21 from the upper surface 24 side with its grounding wire terminals 45 and 46 upward, the terminal 32 portion of each contactor 30 and 31 and the terminal of the grounding plate The position of each terminal 32 coincides with that of the through hole 26, and the width j and thickness k of each terminal 32 are smaller than the corresponding dimensions h and i of the long hole portion 41a of the through hole 41, as described above. The terminal 32 easily passes through the through hole 40 without contacting its periphery. However, at the position of the ground contact 31, the ground plate connection portion 37 protruding upward is connected to the through hole 4.
Its position coincides with the short diameter portion 41b of 0, and a portion of the tip of the connecting portion 37 fits into the short diameter portion 41b, but as described above, the locking protrusion 37c,
Since the width f ₁ between the tips of 37c is larger than the dimension l of the short diameter portion 41b, the ground plate 40 temporarily stops. However, when the ground plate 40 is further pressed toward the insulator top surface 24, the slope 3 of the connection piece 37a
Due to the component force generated at 7d, the pieces 37a, 37a are biased in the direction of reducing the width of the slot 38,
When the width f ₁ becomes equal to the dimension l of the through hole 40, the locking protrusion 37c passes through the short diameter portion 41b of the through hole,
At the same time, the pieces 37a, 37a also return elastically. However, since the distance f ₂ between the stepped portions 37e and 37e of the connecting portion in normal conditions is still slightly larger than the above-mentioned dimension l, the pieces 37a and 37a remain at the above-mentioned stepped portion 37e while retaining their elastic restoring force. Since it comes into elastic contact with the short diameter portion of the through hole 40, and the locking protrusion 37c protrudes from the upper surface of the ground plate, the ground plate 40 is locked and does not come off upward. Note that when the grounding contact 31 is correctly inserted into the insertion hole 26, the step 3 of the connecting portion 37 is removed from the top surface 24 of the insulator.
Since the height up to 7e is approximately equal to the thickness of the ground plate 40, the ground plate 40 is locked by the contact 31 at a position in close contact with the upper surface 24. The connecting portion 37 is brought into sufficient elastic contact with the edge of the through hole 41 of the grounding plate due to the residual elastic restoring force, so that the connecting portion 37, that is, the grounding contact 31 and the grounding plate 40 are brought into stable electrical contact. Become.
As mentioned above, the signal contact 30 and the base portion 33 of this grounding contact 31 have the same shape, and can be inserted into any contact mounting hole 26 using a simple tool. Since the grounding contacts 31 can be removed from the ground, it is easy to change the insertion position or number of the grounding contacts 31 depending on the grounding circuit of the device during assembly or use of the connector. The ground plate 40 is connected to the connecting portion 37 as described above.
The ground contact is integrally locked with the grounding contact and comes into close contact with the upper surface 24 of the insulator, and each protrusion piece 43 provided on one edge 42 is connected to the notch 2 of the side wall 22.
A ground wire terminal 46 is loosely fitted into the notch 23b provided in the other side wall 23, and a ground wire terminal 46 is loosely fitted into the notch 23b provided in the other side wall 23.
Since the outer surfaces of 5 are in contact with each other,
In relation to the dimensional relationship between the width g of the ground plate 40 and the side walls 22 and 23 of the insulator 21, the ground plate 40
is fixed to the insulator 21 without wobbling or coming off even when in use. When the contacts 30 and 31 and the ground plate 40 are attached to the insulator 21, the press-fit slots 34 and 45a, 4 for the terminals of the contacts and the ground plate are
Each part of the insulator 6a, especially the closed end of the press-fit slot, is constructed so that the heights above the top surface of the insulator are approximately equal, which is a necessary condition when connecting the conductor wires, which will be described later. Next, referring to FIGS. 2 and 3, the cover 50 is a rectangular block made of an insulating material, and is formed with a main body 51 and protrudes at right angles from the main body 51 at both longitudinal ends of the main body. engaging arm 52,
It consists of 52. From the upper surface to the lower surface 54 of the main body part 51
A cable penetration groove 55 is provided in parallel to the longitudinal direction of the lower surface 54, and a plurality of terminal fitting holes 56 are arranged in the same longitudinal direction on the lower surface 54. Here, the terminal insertion hole 56 is provided at a position that matches the terminal 32 of each contactor 30, 31 and each ground wire terminal 45, 46 of the ground plate 40 when the main cover 50 and the insulator assembly 20 are combined. The dimensions must be such that the terminal can be inserted into it when connected. However, for manufacturing reasons, the insertion hole 56 does not have to penetrate to the upper surface 53 of the cover, or may have a shape that does. However, the bottom surface 5
It is desirable that the dimension of the fourth side opening in the short side direction be slightly larger than the thickness dimension k of the terminal portion (see FIG. 4a) in order to hold the conductor wire during the next press-fitting of the conductor wire. Further, the lower surface 54 is provided with a plurality of conductor holding grooves 57 in a direction perpendicular to its longitudinal direction. The holding groove 57 has a triangular shape, for example, cut from the lower surface 54 toward the upper surface 53.
It serves to hold each conducting wire 6 or 7 of the flat cable 5 near the apex of the rectangle and to hold the conducting wire when connecting the conducting wire to each terminal. Therefore, the position of each holding groove 57 must be such that it correctly faces the press-fit slot of each terminal 34, 45, 46 when the cover 50 and insulator assembly 20 are coupled. Connect each conductor of the flat cable 5 to each terminal, and connect the cover 50 and the insulator assembly 2.
The procedure for assembling the connector 10 which is connected to the connector 0 is as follows. First, insert the end of the flat cable 5 into the cable penetration groove 55 from the upper surface 53 side of the cover 50.
With the cable passing through the inside and protruding from the lower surface 54, the end of the cable is processed as follows. That is, the insulator at the terminal of the flat cable 5 is cut and removed to the required length to expose each conductor, and then each conductor is bent and formed from near the cut end of the insulator at right angles to the plane of the flat cable. In this case, the signal line 6 and the ground line 7 are bent in opposite directions. That is, in FIG. 2, the signal wire 6 is on the side with the insertion hole 56 into which the terminal 32 of the signal contact 30 is inserted, and the ground wire 7 is on the side with the ground wire terminal 4.
5 and 46 are respectively bent to the side where there is a fitting hole 56 into which they are fitted. As described above, the position and arrangement pitch of each conductive wire holding groove 57 provided on the lower surface 54 of the cover are configured to match the position and pitch of the signal wire 6 and ground wire 7 in the cable. After bending and forming the cover bottom surface 54
By pressing toward the wires, each wire is fitted into the corresponding holding groove 57 and aligned. However, since all of the grounding wires 7 except the one on the outermost side of the flat cable 5 are two in parallel, two of them fit into one holding groove 57. Processing of the terminal of the flat cable and assembling it to the cover 50 as described above is usually done using a dedicated jig (not shown).
This can be done quickly and easily by using . Next, attach the cover 50 that is integrated with the flat cable 5 to the insulator 21 properly.
When the terminals 32, 45, and 46 are brought close to each other while facing the upper surface 24, the tips of the terminals 32, 45, and 46 first fit into the terminal fitting holes 56, and at the same time, the respective conductive wires fit into the press-fitting guide portions 3 of the terminals.
5 and is guided to the open end of the press-fit slot 34. When the cover 50 is further pressed against the insulator 21, each conductive wire is supported on both sides by the holding groove 57, so it is press-fitted into the press-fitting slot 34 without bending, and the two parallel ground wires 7 are press-fitted with two wires stacked one above the other. When the cover 50 is sufficiently pressed against the insulator 21, each conductor wire reaches almost the closed end of the press-fit slot 34 of each terminal, and the conductor wire and the end face of the slot come into pressure contact and are in sufficient electrical contact, and the cover 50 bottom surface 5
4 come into contact with the upper edges 22a and 23a of the side walls 22 and 23 of the insulator 21, respectively, and the cover 50 stops. On the other hand, when the cover 50 and the insulator 21 come close to each other, the engagement arms 52 provided on both sides of the cover 50 are connected to the engagement protrusions 27 provided on both sides 27 perpendicular to the longitudinal direction of the insulator 21.
After elastically deforming and climbing over 7b and 27a, the engaging surface 52a of the engaging arm engages with the lower surface of the engaging protrusion 27a, so that the cover 50 is integrally coupled with the insulator assembly 20 without coming off upward. Ru. Next, the flat cable 5 protruding from the top surface 53 of the cover 50 is bent to the left as shown in FIG. 3, and a cable holder 60 is placed over it. The cable holder 60 is made of a rectangular insulator, and one leg has a short U-shaped cross section as shown in FIG. There is. By covering the cable holder 60 from above the cover 50, the flat cable 5 is held between the cover upper surface 53 and the lower surface of the cable holder 60, so that even if an external force is applied to the cable, the flat cable 5 is held inside the connector. It is held stable without moving. The cable retainer 60 has an engaging arm 61 that is connected to the engaging arm 5 of the cover.
Move forward while sliding on the inside of insulator 2.
By climbing over the first engagement protrusion 27b and being engaged with the protrusion, the cable holder 60 becomes integrated with the insulator 21 and will not easily come off.

できることは云うまでもない。 With the above configuration, this connector is a flat cable that includes a signal line and a ground line, and each signal line is connected to a specified signal circuit on the device side by connecting to a signal contact. , and after connecting the ground wires all together to the ground plate,
The contact plate can be connected to a grounding contact and through the grounding contact to a grounding circuit of the device. Since the grounding contact has the same shape as the signal contact in its base portion and contact piece, it can be inserted into any contact mounting hole of the insulator in accordance with the equipment's grounding circuit to form a grounding circuit. Even if the grounding circuit on the equipment side is changed due to changes in the equipment model or design, all that is required each time is to change the insertion position of the earthing contact or replace it with a signal contact. Since the connector can be easily modified to suit the device, the manufacturer only needs to prepare fewer types of connectors or fewer parts, which is advantageous for mass production and lowers the price. Not only is it convenient to use, but the structure of the connector uses pressure welding to connect the conductor wires of the flat cable and the contacts, so it has many advantages such as not being difficult to work with or causing damage like soldering connections. You can get the same effect. In addition, it goes without saying that in the present invention, many changes can be made in the structure or dimensions of various parts, including the structure of the contactor, without departing from the spirit thereof. For example, in the above embodiment, the grounding contactor is also provided with a terminal for connecting the signal line to connect the signal line of the flat cable, and in that case, the signal line is considered to be the grounding line, but the Since this is not necessarily necessary, the wire may be removed in advance when manufacturing the cable. In that case, a grounding contact with the terminal part removed may be used, but the other structure and functions of this contact are exactly the same as those of the above embodiment, and it can be used under the same conditions. Not even.
