Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coil and a lid for a flexible multi-core flat cable, which are made by casting a large number of parallel conductors with an entire band-shaped insulating coating.

A multicore flat cable consists of a flat ribbon couple in which Vl, each 24 & are arranged in parallel, and a large number of bare conductors in parallel. At the connector mounting part, the entangled winding of each pair of conductors is divided by IIl≦f, and the parallel conductors are There are cables that can be rearranged and used for connection.

As a connection means for the above-mentioned multicore flat cable, a pressure contact connector is generally used. As shown in Fig. 1, this pressure welding connector allows the contact l' to penetrate the insulated part of the multi-core flat cable 2, and as it penetrates, the conductor @3 inside the insulated material is captured, thereby establishing an electrical connection. (pressure welding connection). Such a pressure welding connector is equipped with a connector base 4 on which the contacts 1 are planted, and a cover 5 that presses the multi-core flat couple 2 onto the connector base 4 to allow the contacts 1 to pass through and create a pressure weld connection. becomes essential. In the above pressure welding, the multicore flat cable 2 is held in the connector cover 5, and the above pressure welding is performed after positioning. Alternatively, a positioning means is added, such as by arranging wave-shaped grooves in parallel on the holding surface of the multicore flat cable 2 and aligning the insulating coating portions of the conductive wires 3 with the grooves. However, the above positioning means
It is mainly used to prevent misalignment of the short side lJ direction of the multi-core flat cable 2. ,
The bending of the middle part, which is the habit of multi-core hula and notoriichi bull,
Problems such as pressure welding errors caused by this cannot be solved.

This invention makes it more effective to prevent displacement in the short side direction of the cable, and also effectively prevents vertical displacement in the longitudinal direction of the cable and glare of the cable, and provides accurate It is possible to accurately perform a pressurized connection and to secure a single point of pressure welding which is affected by external forces such as tension applied to the multi-core flanged cable 2 after the pressure welding connection.

In particular, the invention is to drill a hole in the multi-conductor flannel cable to cut the 4 wires, and insert a cut wire extending in the direction of one end of the cable and a cut wire extending in the 11 direction at the other end of the cable. To provide a powerful and effective connector to a connection surface 41°q which is provided for connection between conductive wires and all connectors.

Embodiments of the present invention will be described below with reference to FIG. 2 and subsequent figures.

10 is the multicore flat cable described above.

The cable 10 is provided with a plurality of holes 11 for dividing the conducting wires 12 in a perforation pattern to be described later. By dividing the conductor by the conductor dividing hole 11, a divided conductor 11311.2a extending toward one end of the multicore flat cable io and a divided conductor i 12b extending toward the other end are formed.

The two divided conductive wires 12a and 12b are captured by separate contacts and used for pressure contact connection. Therefore, the conductor dividing hole 11
A hole is punched in the middle of a multicore flat cable having a required length FW, for example, in the middle part. In the drawing, both ends of the cable have been cut out, and the middle part of the cable with the conductor separation hole 11 drilled therein is completely exposed.

A pressure connector 13 is provided to perform pressure connection of the perforated multicore flat cable 10. The pressure contact connector 13 includes a connector base 16 having pressure contact 14.15'e planted thereon as described above, and a connector base 16.
A connector cover 17 is stacked on top of the multi-core flat cable 10 to push the multi-core flat cable 10 therethrough and connect the compression contacts 14 and 15 through the connector cover 17.

In the connector cover 17, as with the previous 1
Wave-shaped core wire alignment grooves 17b are formed in parallel on the inner wall surface (cable attachment surface) of the connector cover between 78 at the same pitch as the core wire pitch.

Further, with or without implementing the cable positioning means, a key 18 is provided protruding from the cable intervening surface of the connector cover 17, that is, the inner surface of the cover where the conductor alignment groove 171) is formed. A plurality of keys 18 are protruded so as to correspond to any one of the fiber dividing holes 11 of the multi-core flat cable 10, preferably a plurality of them, and the keys 18 are inserted into the fiber dividing holes 11 for pressure welding connection. It is used for connection, and the inserted state of both it and is is maintained even after pressure welding connection.

As shown in the figure, the conductor cutting hole 11 for cutting the conductor 12 is preferably rectangular, and the key I8 that can be inserted into the hole is also preferably a rectangular key that fits this.

R11 etc. As shown in FIG. 4A, the key 18 has a side surface 18a facing the end surface of the conductor exposed by the conductor dividing hole 11, and another pair of side faces 18a facing the insulating surface parallel to the adjacent conductors. It has a side surface 18b.

As described above, each side surface of the key 18 and each inner surface of the conductor dividing hole 11 are placed in a fitted state with almost no play, and the multi-core flannel cable lO is placed in the lateral [1] direction or longitudinal direction ( Prevents movement in the axial direction of the conductor.

Alternatively, as shown in FIG. 4B, the prevention of movement in the transversal direction 1] is left to another positioning means, and the conductor end face of the conductor dividing hole 11 is aligned with a pair of 11111 surfaces 18a to prevent movement in the longitudinal width direction.
In some cases, it may be regulated only in

The key 18 is used as a means to secure the side surfaces 18a and 1Sb as shown in FIG.
It is also possible to divide the key pieces 18' into 8' and form an insulating gap between both key pieces 18'. Further, the key 18 has a height that at least penetrates the conductor dividing hole 11. Key 1 as a good example
8 is inserted into the conductor dividing hole 11 as described above, and the multi-core flap and cable 10 are passed through it, and the key-equipped key is further inserted into the handle hole 19 made in the press-contact planting surface of the connector base 16. .

1,! The II handle hole 19 is bored so as to be flush with the key 18, and is placed in communication with the conductor dividing hole 11.

By inserting the key 18 into the conductor dividing hole 11 and the handle hole 19, the relative positions of the multi-core flat cable IO, the connector base 16, and the connector cover 17 are determined.

As mentioned above, the conduction ml of the above multi-core flat goople lO
The hole 11 that cuts 2" is used as a square striped wire in one cable to form all the separate signal lines at the other end of one multicore flat cable. Alternatively, all signal lines may be formed separately, and a ground line may be formed adjacent to each signal line to prevent crosstalk.The latter example is used in the embodiment.

In order to achieve the above purpose, the perforation pattern of the conductor dividing holes 11 in the multi-core cable 10 is shown in Fig. fJ6A.
Examples are as shown in the figure. Corresponding to this, the planting pattern of the pressure contacts 1415 on the connector base 16 is determined. Contact 1 on connector board I6
4 is a signal pressure contact, and contact 15 is a grounding pressure contact. A row of grounding contact groups is arranged between the rows of signal contact groups. The divided conductor 12a'if extending toward one end of the separated cable is captured, and the divided conductor 112b extending toward the other end of the cable is captured by the signal conotaph 1-14 group on the right, and different signals are transmitted to one end and the other end. At the same time, the divided conductor or undivided conductor (non-perforated conductor) adjacent to the divided conductor of each signal line is captured by a grounding contact 15 arranged in the middle to form a ground line. .

In the embodiment, while using the conductor dividing hole 11 for the above purpose,
At the same time, it is used as a positioning means for multi-core flaps, throat cables, or connector elements, and also provides tensile strength against tensile force in the cable axial direction (longitudinal direction) to maintain pressure contact well.

Figure 6A shows conductor dividing holes 1 arranged alternately in parallel conductors 12.
1, and at both ends of the conductor segment If; The non-sprouted conductors adjacent to each perforated conductor are captured by the grounding contact 15 (indicated by a black circle in the figure) to form a ground line (the conductor shown by a matte pattern in the figure), and the conductor wire is 7) Insert the key 18 protruding from the force bar 17 into the hole 11 or into the entire hole 11, and function as a means to prevent the cable from moving when inserted into the connector 13. Alternatively, indicate all the insertion positions of the connector 13 that will benefit the cable 10 in the pressure-fitting position, and immediately apply the pressure-welding position to the cable 10 (with various functions). It made me laugh.

Figure 6B shows that the 4q line dividing hole II in Figure 6A is the conductor &,il.
-In contrast to the type that is drilled in the kiln/ftE, conductor dividing holes are continuously punched over two adjacent conductor conductors, and conductor dividing holes are made so that one non-perforated wire is adjacent between each square unit of perforated conductor. 1) [The conductors 12a and 12b are used as signal conductors, the non-perforated conductor is used as a ground conductor, and the corresponding pressure contacts 14.1 for signal and ground are made of butter.
5, and shows a case in which a key 18 of the same size is inserted into a wide conducting wire dividing hole 11 extending over the plurality of conducting wires 12.

Also, in Figure 6C, a single conductor dividing hole 11 is drilled for each conductor 12-strip in the case of Figures A and B, whereas a plurality of conductor dividing holes 11 are drilled in parallel for each conductor-strip. Indicates the case where The pressure contact pattern of the signal 1 pressure contact 14 and the ground pressure contact 15 is the same as that shown in Figure A, except that there are keys 18 in each of the two conductor dividing holes 11 per line.
This is to secure a connector mounting position that is advantageous to the multi-core flannel cable lO, or to provide tensile strength against pulling in the direction in which the conductor extends, and to connect the signal line and ground by drilling holes in the conductor with the same effect. While making it possible to form a line, the keys 18 are distributed over a wide range, substantially the same as in FIG. 6-0.

Also, Figures 6A to 0 are the same J line segment 1]J "hole 11 -
In contrast to the ZM side divided conductor and the other end divided conductor for all signal conductors, in the case of the opening diagram, both the signal equal conductor and the grounding conductor are separated from one end side divided conductor of the different conductor dividing hole 11 and the other end conductor. A case is shown in which the end-side divided conducting wires are alternately formed, and the signal line and the ground line are formed in a staggered manner.

It is also possible to consider an embodiment in which the conducting wire cutting hole 11 for cutting the conducting wire is not only rectangular but also circular, and a cylindrical postra standing from the cover is inserted into this.

The invention also provides another embodiment in which the key 18 is provided protruding from the contact planting surface (cable intervening surface) of the connector base 1G and is inserted into the conductor dividing hole 11 from the direction opposite to the key of the cover 17. include. That is, the key 18 is connected to the connector 1
The cable intervening surface of No. 3 is inserted into the conductor dividing hole 11 with a protruding awn.

The number of cores in the multicore flat cable 10 has been increasing in recent years, and the cables have accordingly tended to become wider. By regulating both ears of the flat cable 10 as in the past,
By simply aligning the outer sheath of the cable conductors with shallow corrugated grooves, it is difficult to correct the bending behavior of the cable, and effective positioning cannot be expected. It's safe to say that there are none. When the cable bends, which is the most noticeable phenomenon, it inevitably causes a slight deviation in the one-to-one correspondence between the pressure welding contact and the conductor, causing the conductor to penetrate into a different outer sheath, or being pressure welded in an abnormal posture. , incorrect connections, poor connections, etc., and highly reliable pressure welding connections cannot be expected.

In the present invention, even with a wider multi-core flat cable, the connector 13 is inserted into the conductor dividing hole 11 drilled in the middle part of the cable, which tends to bend easily. By doing this, the bending can be eliminated and a flat state can be created, which can be used for pressure welding. Therefore, it effectively copes with the increase in the number of cores and width of flat cables, and ensures highly reliable pressure welding.

As mentioned above, it also has the function of indicating the pressure welding position for the flat cable, allowing the connector to be installed and connected at the appropriate position.In addition, even after pressure welding, the insertion of the key 18 and the conductor dividing hole 11 is maintained, and the fishing line axis center What is the good tensile strength for the tensile force in the direction? 4j to maintain proper pressure contact.

According to the invention, the rod wire can be moved 1θ without using the positioning means that has been used up to now to restrict the ears of the flat cable, or the positioning means that supports the conductor in the shallow groove of the conductor sheath on the surface of the four cables. It can be effectively used as a positioning means to prevent the cable from shifting in the short and middle directions and in the longitudinal direction by simply setting the dimensions of the key 18 that is "I in the hole 11". Note that this does not preclude use in combination with these conventional positioning means.
