Description

  The present invention relates to a cable clamp for protecting a connector attached to an end of a flat cable.

  Conventionally, a flat cable in which a plurality of parallel electric wires are arranged in a plane and joined together is used. Such flat cables are widely used in various fields. For example, it is used in various places in vehicles such as automobiles.

  And a cable clamp is used in order to route such a flat cable (for example, refer patent document 1).

JP-A-5-160580

  Since the cable clamp described in the above-mentioned Patent Document 1 is configured to change the direction of the cable clamp by clamping the flat cable in a bent state, a large load acts on the flat cable suddenly. When pulled, it did not have a function to protect the terminal portion of the connector attached to the end of the flat cable.

  In order to solve the above-mentioned problems, the present invention provides a first cable clamping portion capable of clamping the vicinity of the connector of a flat cable having a connector attached to an end portion, and a flat cable from the first cable clamping portion. A second cable sandwiching portion capable of sandwiching a position separated by a surplus length to be applied to the cable, between the first cable sandwiching portion and the second cable sandwiching portion, It is characterized by a cable clamp having an internal connecting portion that can be connected and separated from a separated state to a state adjacent to each other while bending the flat cable.

  According to the present invention, the following effects can be obtained by the above-described configuration. That is, with respect to the first cable sandwiching part sandwiching the vicinity of the flat cable connector, the second cable sandwiching part sandwiched at a position separated by the extra length of the flat cable is flattened from the separated state. By making the cables close to each other while being bent and then connecting them using the internal connecting portion, the flat cable can be bent to easily form a detour portion having a certain length.

It is the whole cable clamp perspective view concerning the example of the present invention. It is a disassembled perspective view of the cable clamp of FIG. It is a whole perspective view which shows the use condition of the cable clamp of FIG. It is the whole perspective view which looked at FIG. 3 from diagonally lower side. It is a whole perspective view which shows the modification usage example of a cable clamp. It is a perspective view which shows the state which bends a flat cable. It is the perspective view which looked at FIG. 6 from the other side.

The second cable clamping portion 13 is used to clamp the position. And the 1st cable clamping part 11 and the 2nd cable clamping part 13 are brought close to the mutually adjacent state, and it connects with the internal connection part 14. FIG. As a result, the cord-like member 21 between the first cable sandwiching portion 11 and the second cable sandwiching portion 13 is bent, and the bypass portion of the flat cable 1 is formed inside the cord-like member 21.

  When changing the direction of the flat cable 1, one internal coupling portion 14 is removed, and the first cable clamping portion 11 and the second cable clamping portion 13 are rotated around the other internal coupling portion 14. By moving, the flat cable 1 can be bent easily.

  In addition, by connecting the plurality of cable clamps 3 using the external connecting portion 25, it is possible to form multiple bypass portions.

  Furthermore, when the clip base 11a and the lock plate 11b of the first cable clamping part 11 are separated, and the clip base 13a and the lock plate 13b of the second cable clamping part 13 are separated, As shown in FIG. 5, the flat cable 1 is obtained by interposing an intermediate plate 18 having a claw portion 11d and a claw receiving portion 11e (or a claw portion 13d and a claw receiving portion 13e of the locking portion 13c) of the locking portion 11c. It is possible to form a multi-layered detour portion while fixing the multi-layer structure.

  <Effect> According to this embodiment, the following effects can be obtained.

(Effect 1)
The second cable sandwiching portion 13 sandwiching the position separated by the extra length of the flat cable 1 is separated from the first cable sandwiching portion 11 sandwiching the vicinity of the connector 2 of the flat cable 1. The flat cable 1 is bent from the state and brought close to the adjacent state, and then joined by using the internal connecting portion 14, whereby the flat cable 1 is bent to easily form a detour portion having a certain length. Can do. Even if the load is suddenly applied to the flat cable 1 and pulled by the detour portion, stress concentration on the terminal portion of the connector 2 attached to the end portion of the flat cable 1 is avoided. The connection state of the part can be safely protected.

(Effect 2)
The first cable sandwiching portion 11 and the second cable sandwiching portion 13 are connected together in advance by a cord-like portion 21 having a length corresponding to the extra length, thereby reducing the number of parts. The first cable holding part 11 and the second cable holding part 13 can be easily attached to the cable, and the extra length can be accurately set to a predetermined length. Further, loss of the first cable sandwiching portion 11 and the second cable sandwiching portion 13 is prevented, and handling of the first cable sandwiching portion 11 and the second cable sandwiching portion 13 is facilitated. be able to.

(Effect 3)
Since the cable-shaped part 21 has the hinge part 23 at the middle part in the length direction, the cable-shaped part 21 can be easily and accurately bent around the hinge part 23 so that the flat cable 1 always has a constant detour part. Can be formed.

(Effect 4)
Since the first cable sandwiching portion 11 and the second cable sandwiching portion 13 have the external connection portion 25, the first cable sandwiching portion 11 and the second cable sandwiching portion 13 are connected to the connector 2. Alternatively, it is possible to freely connect to and disconnect from external parts (such as another cable clamp 3).
