Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a perforated terminal stack suitable for collectively fastening and fixing a plurality of perforated terminals that are used as ground terminals for car interior wiring. It relates to a mating structure.

[Prior Art] When assembling a vehicle wire harness to a vehicle body, a ground terminal of the wire harness is fixed to a vehicle body ground point by screwing. Normally, one grounding terminal is screwed to one grounding point, but when the wiring inside the vehicle becomes complicated due to the increase in electrical equipment as recently, multiple grounding terminals are screwed together to one grounding point. Stopping things are happening.
This is because from the part of the wire harness 11 to the ground terminal when manufacturing the wire harness, as shown in Fig. 5.
Pull out the multiple wires 13a to 13c with 12a to 12c and install these ground terminals 12a to 1c when assembling to the vehicle body.
It is done by stacking 2c and screwing them all together at one earth point.

〔Task〕

However, if a structure is used in which a plurality of ground terminals are screwed together, it is possible that some of the ground terminals may be forgotten to be tightened when assembled to the vehicle body, which is a problem in terms of reliability.

To solve this, it is possible to combine the ground terminals into one using a joint connector,
The cost of using the joint connector is high.

[Means for solving problems]

In view of the above problems of the prior art, the present invention provides a superposed structure of perforated terminals suitable for collectively fastening and fixing a plurality of perforated terminals used as ground terminals and the like. The structure consists of a stack of multiple perforated terminals sandwiched between an upper cover and a lower cover.The upper cover and the lower cover are respectively located at the center of the flat plate part, with the perforated terminals stacked together. The present invention is characterized in that it has a tubular portion that fits into each other in the hole, and that the tubular portion has a retaining portion that engages when fitted together.

[Action]

This perforated terminal overlapping structure is configured by sandwiching a plurality of perforated terminals screwed in one place at the time of manufacturing a wire harness between an upper cover and a lower cover. When the tubular portions of the upper cover and the lower cover are fitted to each other, the retaining portions are engaged with each other so that they cannot come off. Therefore, when the wire harness is assembled to the vehicle body, it can be handled in the same manner as a single perforated terminal.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 (a) and 1 (b) are a sectional view and a plan view of a perforated terminal overlapping structure according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view thereof. The electric wires 13a to 13c and the perforated terminals 12a to 12c attached to the ends thereof are the same as conventional ones.

The present invention stacks these perforated terminals 12a-12c,
This is sandwiched between the upper cover 14 and the lower cover 15.

As shown in FIGS. 3 (a) and 3 (b), the upper cover 14 has a cylindrical portion 17 projecting downward at the center of a flat plate portion 16 having a perforated disc shape, and the cylindrical portion 17 has an outer peripheral surface that is pulled out. The stopper projection 18 is formed. As shown in FIGS. 4 (a) and 4 (b), the lower cover 15 has a cylindrical portion 20 projecting upward in the central portion of a perforated disc-shaped flat plate portion 19, and the inner peripheral surface of the cylindrical portion 20. The retaining recess 21 is formed on the inner surface.

The tubular portion 17 of the upper cover 14 and the tubular portion 20 of the lower cover 15 are formed in such a size that they can be fitted into each other in the holes of the perforated terminals 12a to 12c that are overlapped with each other. The protrusion 18 and the retaining recess 21 are engaged with each other as shown in FIG. 1A, and the upper cover 14 and the lower cover 15 cannot be separated.

Due to this structure, when assembling the wire harness to the vehicle body, it can be handled like a single perforated terminal, and the multiple perforated terminals 12a-12c must be securely screwed together. Is something that can be done.

It should be noted that, in order to reliably apply tightening pressure to each of the perforated terminals 12a to 12c at the time of screwing, it is desirable that the retaining projection 18 and the retaining recess 21 are engaged with each other with some play in the vertical direction. .

In the above embodiments, the case where three perforated terminals are superposed is shown, but the number of perforated terminals to be superposed is not particularly limited. The protruding height of the cylindrical portion of the upper cover or the lower cover is determined according to the number of perforated terminals.

Further, the structure of the retaining portion is not particularly limited. For example, the relationship of the concavities and convexities may be opposite to that in the above embodiment, or another elastic coupling structure may be used.

[Effect of device]

As described above, according to the present invention, a plurality of perforated terminals screwed to one place are sandwiched between the upper cover and the lower cover to be integrated, so that one hole is assembled when the wire harness is assembled to the vehicle body. It can be handled in the same way as open terminals, and it is possible to reliably prevent forgetting to tighten some of the open terminals. Also, when the upper cover and the lower cover are fitted to each other with the tubular parts, the retaining parts are engaged and do not come off. Therefore, the assembly is very simple, and the only necessary parts are the upper cover and the lower cover. It has the advantage of low cost.
