BACKGROUND OF THE INVENTION
The present invention relates to a flat cable with a connector .
[0002]
[Prior art]
As shown in FIG. 4, a plurality of strips of copper or aluminum or the like that are arranged in parallel, such as 0.15 mm in thickness and 1.5 to 3.0 mm in width, are arranged on the electrical wiring of an electric device or an automobile. A flat cable 3 having a structure in which a flat conductor 1 is collectively covered with a flat insulating coating 2 made of plastic such as polyethylene terephthalate has been used.
[0003]
In such a flat cable 3, as shown in FIG. 5, a plurality of independent flat cable portions 3 </ b> A and 3 </ b> B are formed by being cut and trimmed in a flat insulating coating 2 between adjacent flat conductors 1. As shown in FIG. 4, a terminal plate portion 5b is connected to the independent flat cable portions 3A and 3B on the female terminal body 5a, and crimp pieces 6 are provided on both sides of the terminal plate portion 5b in the width direction. Each crimp piece 6 of the connection terminal 7 having the structure of standing upright is pierced at a position corresponding to the flat conductor 1 so that the corresponding flat conductor 1 and the connection terminal 7 are electrically connected to each other and the flat cable portions 3A and 3B. As shown in FIG. 5, the terminal connecting portion 8 is formed by bending and crimping the tip end portion of each crimp piece 6 penetrating the cable, thereby forming a flat cable 9 with a terminal. It has been subjected.
[0004]
Usually, in such a flat cable 9 with terminals, the connection terminals 7 connected to the independent flat cable portions 3A and 3B are juxtaposed in the lateral direction in the lateral connector housing 10 as shown in FIG. In addition, each terminal accommodating chamber 11A, 11B is accommodated so that each terminal connecting portion 8 is also built in, and is secured by a locking member (not shown) to form a connector 12, thereby forming a flat cable 13 with a connector.
[0005]
However, in reality, not all the connector housings 10 are designed exclusively for the flat cable 9 with terminals, and because of the economic reasons and the influence of the location of the connector 12, as shown in FIG. Each of the connection terminals 7 is housed in each of the terminal housing chambers 11A and 11B arranged in the vertical direction in the conventional connector housing 10 so that the terminal connection portion 8 is also built in, and is pulled out by a locking member (not shown). Some of them are stopped to form a connector 12 and become a flat cable 13 with a connector. Reference numeral 14 denotes a lock member that locks the connector housing 10 by fitting the connector housing 10 into a connector housing (not shown) of the connection partner.
[0006]
In this case, the connection terminals 7 to be inserted into the terminal accommodating chambers 11A and 11B are directional, and may have to be inserted in the same direction both up and down, or in the opposite direction. is there.
[0007]
When the terminal housing chambers 11A and 11B exist vertically in the connector housing 10 as described above, the adjacent flat conductors 1 are adjacent to each other as shown in FIG. 7 so that the flat cable portions 3A and 3B can move independently in advance. Cuts 4 are made in the flat insulation coating 2 between them, and as shown in FIG. 8, one flat cable portion 3B is twisted to be present on the other flat cable portion 3A, and the upper and lower terminal accommodating chambers shown in FIG. In 11A and 11B, each connection terminal 7 was accommodated so that its terminal connection portion 8 was also built in.
[0008]
In addition to this, as the connector housing 10 that is actually used, for example, as shown in FIG. 9, a housing in which terminal accommodating chambers 11A, 11B, 11C, and 11D are provided vertically and horizontally is used. A flat cable 3 having a flat conductor 1 is cut into a flat insulating coating 2 between two flat conductors 1 adjacent on one end side to form independent flat cable portions 3A and 3B. A notch 15 longer than the notch 4 is formed between the flat conductors 1 to form independent flat cable portions 3X and 3Y, and a notch 16 having the same length as the notch 4 is formed between the third and fourth flat conductors 1. To form independent flat cable portions 3C and 3D, and connect the connection terminals 7 to the flat cable portions 3A to 3D using the crimp pieces 6 as described above. The terminal-equipped flat cable 9 is configured, and each connection terminal 7 is accommodated in the corresponding terminal accommodating chambers 11A to 11D so that the terminal connection portion 8 is also built in, and is secured by a locking member (not shown). 12 may be formed as a flat cable 13 with a connector.
[0009]
If an external force such as bending or twisting is applied to the flat cable 9 with a terminal inserted into the connector housing 10 in this way, the force reaches the terminal connecting portion 8 in the connector housing 10 and the terminal connecting portion 8 There is a risk of breaking the insulation.
[0010]
For this reason, normally, as shown in FIGS. 10 and 11, the connection terminals 7 of the flat cable 9 with terminals are respectively inserted into the terminal housing chambers 11A and 11B in the connector housing 10 to prevent them from being pulled out and set. Then, a flat cable connector retainer 18 having a retainer body 17 formed of resin or the like for holding the flat cable portions 3A and 3B connected to the connection terminals 7 is inserted from the rear ends of the terminal accommodating chambers 11A and 11B. Then, the presser 19 is pressed.
[0011]
In this way, when an external force is applied to the flat cable portions 3A and 3B outside the connector housing 10, the influence of the external force is blocked by the presser portion 19 and does not act on the terminal connection portion 8. The connection part 8 can be protected.
[0012]
[Problems to be solved by the invention]
However, the conventional method for preventing external force by the flat cable connector retainer 18 is effective against a certain amount of bending stress of the flat cable portions 3A and 3B, but it can be bent into a flat cable by a stronger force. There was a weak problem with respect to stress and tensile stress.
[0013]
In addition, the use of in-vehicle flat cables has been used in parts where wiring and connection of flat cable connectors are relatively easy, but recently, the in-vehicle wiring of flat cables has increased. It is also being used in narrow areas and areas where flat cable connectors must be connected by groping. In such a part, it is considered that abnormal bending or tension that has been difficult to imagine until now is applied during flat cable routing and connection work, and external force acts immediately on the terminal connection part between the connection terminal and flat cable. It is desirable to establish protective measures to prevent this.
[0014]
The objective of this invention is providing the flat cable with a connector which can prevent that external force acts on the terminal connection part of a connection terminal and a flat cable.
[0015]
