Abstract

PURPOSE:To protect a cable from being tangled and twisted and prevent a weld section from being broken. CONSTITUTION:A resilient body 14 is loaded in a gap between the stepped section 4 of a stepped hole 5 drilled through a body 1 and the different-diameter stepped section 10 of a through-terminal 7, in resilient state. As a result, the terminal 7 is energized in a direction for detachment from the body 1, and a retaining ring 15 becomes free from being loosened, due to the side wall of the peripheral groove 6 of the body 1 and the peripheral groove 11 of the terminal 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cable terminal,
In particular, a through-hole terminal having a different-diameter step portion is fitted into a stepped hole penetrating the body, and is inserted in a circumferential groove provided in the large-diameter hole portion of the body and the large-diameter portion of the through terminal opposite to this. The present invention relates to a cable terminal in which both are locked by a retaining ring and the outer end of the large diameter portion of the through terminal is welded to the body.

[0002]

2. Description of the Related Art Conventionally, in this type of cable terminal, a threaded portion is formed in a small-diameter hole portion of a stepped hole penetrating the body, while a through terminal having a different diameter stepped portion is formed in the stepped hole. The threaded portion formed on the small diameter portion is screwed into and fitted into the threaded portion of the small diameter hole portion, and is inserted into the circumferential groove provided in the large diameter hole portion of the body and the large diameter portion of the through terminal facing the large diameter hole portion. Both of them are locked by a mounted retaining ring, and the outer end portion of the large diameter portion of the through terminal is welded to the body.

[0003]

This conventional cable terminal has a structure in which the small-diameter hole portion of the body and the small-diameter portion of the through terminal are screwed together, so it is necessary to rotate the through terminal, and the cable is attached to the through terminal. When connected, there is a problem of cables getting entangled or twisted.

Further, there is a problem in that a force may be directly applied to the welded portion and the welded portion may be broken due to looseness due to the clearance between the retaining ring and the circumferential groove.

Therefore, an object of the present invention is to provide a cable terminal which does not cause entanglement or kinking of cables and which can prevent the destruction of the welded portion.

[0006]

In the cable terminal of the present invention, a through-hole terminal having a different diameter step portion is fitted into a stepped hole penetrating the body and the large diameter hole portion of the body is opposed to the through terminal. A cable terminal in which both are locked by a retaining ring interposed in a circumferential groove provided in the large diameter portion of the through terminal and the outer end of the large diameter portion of the through terminal is welded to a body, An elastic body is mounted between the stepped portion of the stepped hole and the stepped portion of different diameter of the through terminal.

[0007]

In the above means, the elastic body urges the penetrating terminal in the direction of coming out of the body, and the retaining ring is clamped by the side wall of the peripheral groove of the body and the side wall of the peripheral groove of the penetrating terminal, so that the retaining ring is loose. Disappears.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a cable terminal according to an embodiment of the present invention.

The body 1 has a stepped hole 5 formed by connecting a large-diameter hole 2 and a small-diameter hole 3 via a step 4, and the stepped hole 5 has a large-diameter hole 2 formed therein. A peripheral groove 6 is provided in the. On the other hand, the through terminal 7 is provided with the stepped hole 5 of the body 1.
A large diameter portion 8 having the same outer diameter as that of the large diameter hole portion 2 and an appropriately short diameter, and a small diameter portion 9 having the same outer diameter as that of the small diameter hole portion 3 of the stepped hole 5 and an appropriate length as a different diameter step portion 10. The large-diameter portion 8 has a peripheral groove 11 formed at an appropriate position.
And the small diameter portion 9 has a plurality of cables 1 connected to each other.
2 and 13 are connected.

In the stepped hole 5 of the body 1, the penetrating terminal 7 is provided with an elastic body 14 made of metal, rubber, plastic or the like between the stepped portion 10 of the different diameter and the stepped portion 4 of the body 1. Are fitted and inserted into the peripheral groove 6 of the body 1 and the peripheral groove 11 of the through terminal 7 with the retaining ring 16 interposed therebetween, and the outer end portion of the large diameter portion 8 of the through terminal 7 Are fixed by the body 1 and the welded portion 16.

In the cable terminal having the above construction, the elastic body 14 urges the penetrating terminal 7 in the direction of coming out of the body 1 (to the left in FIG. 1), and the retaining ring 15 serves as a side wall of the circumferential groove 6 of the body 1. It is sandwiched by the side wall of the circumferential groove of the through terminal 7, and the rattling of the retaining ring 15 is eliminated.

Therefore, the body 1 and the penetrating terminal 7 are integrated to prevent relative movement of the two in the axial direction,
The weld 16 is not destroyed.

Further, since it is not necessary to rotate the through terminal 7, even if the cables 12 and 13 are connected, they will not be entangled or twisted.

[0015]

As described above, according to the present invention, the penetrating terminal is biased by the elastic body in the direction of coming out of the body, and the retaining ring is sandwiched between the side wall of the peripheral groove of the body and the side wall of the peripheral groove of the penetrating terminal. Since the rattling of the snap ring is eliminated, the body and the through terminal are integrally prevented from moving relative to each other in the axial direction, and the welded portion is not destroyed.

Further, since it is not necessary to rotate the through terminal as in the conventional case, the cable is not entangled or twisted.
