Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a mounting structure of a case body for a capacitor mounted with a holding clamp to prevent noise in a car radio.

[Prior art]

Conventionally, there have been various mounting structures for capacitors to prevent noise from radios in automobiles, etc., such as cylindrical shapes and rectangular housing types, and the capacitor mounting structure when mounting with clamps has different specifications depending on the car body, such as horizontal capacitors and vertical capacitors. etc.

In the mounting structure of the case body for such a capacitor, as shown in Fig. 4, a small connector 5' and a lead wire 6' are connected, which is the opposite of the structure in which the lead wire 6' is connected. Even if the case body 2' of the horizontal capacitor 1, which is provided with a bifurcated bracket 7' on the side, is mounted by tightening it into the fastening hole 4', (1) the connector 5' may dangle; Interference with other objects and generation of abnormal noise.

(2) Edges of the lead wire 6' etc. are interfering with the case body 2' or other objects, or the lead wire is not jammed during installation.

(3) Because mounting screws are used when tightening, there are problems such as limitations on the mounting position on the tightening plate. Further, it has a drawback that the attached wire harness cannot be tightened at an arbitrary position.

[Purpose of invention]

This invention was devised to eliminate various drawbacks of the mounting structure of the case body for the noise prevention capacitor of the above-mentioned car radio, and the purpose of this invention is to The case body is made by directly connecting and integrating a synthetic resin housing containing a capacitor for noise prevention of a radio, and a connector that directly connects the wire harness to the capacitor without using any lead wires in the middle. The main body of the case for the capacitor used to prevent noise from car radios is mounted in the middle of the wire harness for indoor wiring, and the case body is held in place at important points on the wire harness, and the mounting screws are It seeks to provide a capacitor structure mounted with a retaining clamp so that it is not necessary.

[Structure of the invention] In other words, the gist of the capacitor structure of this invention, which is attached with a holding clamp to prevent noise in automobile radios, is that a synthetic resin casing encloses a capacitor for preventing noise in automobile radios. The case body is constructed by integrating the capacitor and the connector that connects the wire harness.
A string-like holding clamp for supporting the case body is disposed on the outer surface of the case body, and one end of the clamp is elastically engaged with an engagement hole at the other end of the clamp.

〔Example〕

Hereinafter, an embodiment of the case body mounting structure for a capacitor mounted with a holding clamp to prevent noise in a car radio of this invention will be described in detail with reference to the drawings.

First, Figure 1 is an overall perspective view of the capacitor structure attached with a holding clamp, Figure 2 is an overall perspective view of the capacitor structure attached to the vehicle side wire harness, and Figure 3 is a capacitor along the line of arrow A in Figure 1. FIG. 3 is an overall front view of the structure.

In the figure, 1 is a horizontal capacitor, and 2 is a case body of the horizontal capacitor 1, such as a rectangular case type.

W is a fastening wire harness, 4 is an engagement hole drilled corresponding to the mating position of the fastening wire harness W, etc. of the holding clamp 7, 5 is a connector, 6 is the lead wire, and 7 is a thin string-shaped wire. The holding clamp is formed to have an insertion piece and a square hole for locking, 8 is a fastening part of the holding clamp 7, and 9 is a joint on the outer surface of the case body 2 of the horizontal capacitor 1.

Therefore, as shown in Figs. 1 to 3, when it comes to the case body 2 of the horizontal capacitor 1 formed into a rectangular case made of synthetic resin, it is especially important to At a proper location, the joint portion 9 is brought into contact with the case body 2 of the capacitor 1 described above, and a string-like holding clamp 7 of the case body 2, which is directly connected to the connector 5, is wrapped around the connector 5. The insertion piece as shown is inserted from one side into the tightening portion 8 of the holding clamp 7 and tightened.

Then, the string-like holding clamp 7 is wound and routed halfway around the wire harness W to be attached, and here, the case body 2 of the capacitor 1 is
By elastically engaging the fastening portion 8 of one end of the holding clamp 7 with the engagement hole 4 of the other end of the clamp 7 and tightening, the case body 2 can be held and attached. be.

[Effect]

As described in detail in the above explanation of the configuration of this invention, a synthetic resin casing containing a capacitor for noise prevention in a car radio and a connector that connects this capacitor to a wire harness are directly connected. It is integrated to form the case body,
It is placed at a suitable place in the middle of the wire harness of the car's wiring, and serves as a capacitor joint for noise prevention in the car radio, and string-like holding clamps are placed at strategic points on the case body. By elastically engaging one end of the clamp of the capacitor body with the engagement hole, it became possible to hold and attach the case body 2 by tightening the attached wire harness midway.

[Effect of idea]

As described above in detail, this invention is based on the mounting structure of the case body 2 for a capacitor attached with a holding clamp to prevent noise in an automobile radio. The resin case and the connector that connects this capacitor to the wire harness are directly connected and integrated to form the case body, and it is placed in a suitable place in the middle of the wire harness of the car's wiring, and is used to connect the car radio. This is a capacitor joint for noise prevention, and string-like holding clamps are placed at key points on the case body, and one end of the clamp on the capacitor body is elastically engaged with the engagement hole. The case body 2 can be held and attached by tightening the wiring harness in the middle of the wire harness inside the car.

Then, as shown in Fig. 2, a thin string-like holding insertion piece is placed at a suitable place in the middle of the wiring for the case body 2 of the horizontal capacitor 1, which has a structure in which it is directly connected to the connector, and the other end of the aforementioned clamp is inserted. By engaging with the engagement hole 4 of the connector, (1) the connector 5 does not dangle, and interference with other objects and generation of abnormal noise can be prevented.

(2) The case body 2 with the built-in lead wire 6 will not cause any edge interference with other objects or jamming during installation, resulting in defects.

(3) When tightening with the holding clamp 7, there is no need to use a special mounting bracket or mounting screws.
There are no restrictions on the mounting position to the fastening object,
There are advantages such as the ability to tighten the object with the holding clamp 7 at any arbitrary position of the wire harness W or the like.

In this way, it can be said that the mounting structure of the case body 2 for the capacitor mounted with a holding clamp to prevent noise in an automobile radio of this invention is truly a highly practical and valuable invention.
