Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a protective device for a wire harness, and is particularly useful for improving reliability in the connection between a low-voltage electric wire conductor for an automobile and a press-contact type terminal.

B. Conventional technology and its problems The wiring of the wire harness (wire assembly for automobiles) is
Generally, as shown in Fig. 6, a branch line w is branched out from the middle of the main line W and connected directly to the connector b provided at the load a at the end, or a branch line connector c is used to make a distribution relay connection. It's on.

Since such a trunk line W has a large number of wires and is quite heavy, it is necessary to protect the straight sections with synthetic resin troughs or cylindrical bodies, and to attach T-shaped support members to the branch sections J. Therefore, they are protected by means such as attaching them to the vehicle body. However, branch lines w branched from the main line W, branch connectors c, etc. come in various forms, such as those that are fixed to the vehicle body or those that are suspended in the air, and are not properly protected. .

Therefore, not only does it take time to install the wire harness and a large installation space is required, but also the connector c is a pressure-contact type terminal for connecting low-voltage wires (a type of terminal in which the wires are press-fitted into a slot). ), there were problems such as the load and tensile force of the wires acting directly on the connected portions, causing loosening and disconnection, resulting in reduced reliability.

The purpose of this invention is to solve the above-mentioned problems, improve productivity by shortening wiring harness installation time and reducing space, and to create wires that can connect with high reliability even in the case of low-voltage wires. To provide protective equipment for harnesses.

C. Means for Solving Problems To explain the present invention based on the drawings, in FIGS. 1 to 3, 1 shows side walls 3 on both sides of the bottom plate 2,
3' is a gutter-like body made of synthetic resin, and a partition wall 4 extending in the longitudinal direction is provided on the bottom plate 2 of the gutter-like body, and a holding portion 5 for the wire harness W is formed between it and one side wall 3. In this partition wall 4, a plurality (two in the illustrated example) of electric wire insertion grooves 8 for wiring and fixing electric wires are formed at appropriate intervals, as will be described later.

On the other hand, on the inner surface of the other side wall 3', there is provided a cassette mechanism 7 for tilting and fixing the electric wire connecting connector 6.

As shown in FIG. 4, the electric wire connecting connector 6 is configured as a press-contact connector in which a chain-shaped press-contact type terminal 10 with a wire press-fitting slot 11 is attached to a housing 9, and a plug-in terminal is attached to both sides of the bottom of the housing 9. A collar 12 is provided protrudingly.

In the illustrated example, the cassette mechanism 7 includes a plug-in fitting frame 13 that corresponds to the collar 12 and is provided obliquely at an inclination angle θ from the vertical direction, and a flexible lock claw 14 is protruded from the upper end of the frame 13. It has a set configuration.

D. Effect: In the assembly work of the wire harness W, the branch wire W branched from the middle is connected in advance to the pressure contact type terminal 10 from the inlet side A of the connector 6, and the outlet side B of the connector 6 is connected to each load. Connect the branch line w′.

Next, the wire harness W is attached to the holding part 5 of the gutter-like body 1.
, pass the branch wire w through the wire insertion groove 8, insert the collar 12 into the fitting frame 13 with the inlet side A of the wire connection connector 6 (housing 9) facing downward, and insert it into the fitting frame 13.
It is locked by the lock pawl 14.

As a result, the connector 6 is fixed obliquely as shown in FIG. 3, and its outlet side B is also inclined. Therefore, each branch line w' facing the load can be wired neatly along the side wall 3' without overlapping or intertwining with each other at the outlet of the connector 6, and the load due to its own weight on the internal pressure contact terminal 10 can be avoided. is reduced. On the other hand, the branch wire w branched from the wire harness W becomes a kind of fixed state by passing through the relatively narrow wire insertion groove 8, and the previous hanging state is eliminated.

E. Embodiment FIG. 5 shows another embodiment of the cassette mechanism, in which a flexible lock arm 15 is provided on the collar 12 of the housing 9, and the lock arm 15 enters into the upper half of the insertion frame 13. A lock chamber 17 is provided, and a locking hole 18 for a projection 16 of the arm 15 is provided. In this case, the housing 9 can be easily attached and detached by pressing the lock arm 15 against the collar 12 side.

In this way, the cassette mechanism of the connector may be of any type as long as it allows the connector to be attached or detached with a single touch without using other parts such as screws.

The above describes an example of a pressure welding connector in which a pressure welding type terminal is attached to a connector for connecting electric wires.
It can be used in exactly the same way for female and male connectors that connect ordinary female terminals and male terminals.

Effects of the invention When the protective equipment of the invention is used, the wire harness, its branch parts, branched and externally connected branch lines (wires), and connectors for connecting the wires are collectively housed and protected, so it is easy to assemble the wire harness. It is possible to improve productivity by reducing installation time and wiring space. In addition, since the connector is fixed diagonally, reducing the load and tensile force on the wires being taken out, even when pressure welding connectors are used, they are less likely to loosen or break, improving the reliability of electrical connections. can be increased.
