Abstract

PURPOSE:To prevent a disconnection caused by an external vibration by making the length of a cable pressing member shorter than that of a cable supporting member. CONSTITUTION:The length (m) from the top end part 3a of a housing body 3 to the lower surface end part 4a making contact with a cable 1 of a cable pressing member 4 is shorter than the length (n) from the top end part 3a of the housing body 3 to the upper surface end part 5a making contact with the cable 1 of a cable supporting member 5. By constituting the cable pressing member 4 and the cable supporting member 5 in such a manner that the lower surface end part 4a and the upper surface end part 5a are never situated on the same vertical line, the stress added to the cable 1 by an external vibration is dispersed to two points of the lower surface end part 4a and the upper surface end part 5a, and a disconnection caused by the external vibration can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector having an electric wire pressing member for electrically connecting electric wires.

[0002]

2. Description of the Related Art Recently, in order to streamline the wiring work of equipment, particularly the wiring of motors to equipment, the one that uses a connector at the tip of the lead wire is widely used, and the structure of the connector itself is used. By making improvements, we are working to significantly improve the wiring work and costs.

A conventional connector will be described below.
As shown in FIG. 3, the terminal 2 crimped to the tip of the electric wire 1 is inserted into the housing main body 3, the terminal 2 is fitted into the pawl 8, and the electric wire pressing member 4 connected to the housing main body 3 by the hinge 7 is provided. Is rotated as indicated by an arrow A to clamp the electric wire 1 between the electric wire supporting member 5 and the electric wire pressing member 4. In the figure, 4b indicates the lower end of the electric wire pressing member 4 in contact with the electric wire 1, 5b indicates the upper end of the electric wire supporting member 5 in contact with the electric wire 1, and the lower end 4b and the upper end 5b are on the same vertical line. positioned.

[0004]

However, in the above-mentioned conventional structure, the vibration applied from the outside causes the lower end portion 4b of the wire pressing member 4 and the upper end portion 5b of the wire supporting member 5 to keep the electric wire 1 at the same position. There is a problem that stress is applied from the upper and lower surfaces and the wire is easily broken.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a connector in which disconnection caused by external vibration is prevented.

[0006]

To achieve this object, the connector of the present invention has a structure in which the length of the wire holding member for holding the wire is shorter than the length of the wire supporting member.

[0007]

With this structure, the stress applied to the electric wire due to the vibration from the outside is dispersed to two points on the electric wire which are separated from each other.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2 showing an embodiment of the present invention, the same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 1 and 2, the length m from the tip portion 3a of the housing body 3 to the lower surface end portion 4a of the wire holding member 4 which contacts the electric wire 1 is set from the tip portion 3a of the housing body 3 to the electric wire support. Upper surface end portion 5 of the member 5 in contact with the electric wire 1
The length n up to a is made shorter so that the lower surface end 4a and the upper surface end 5a are not located on the same vertical line.

As described above, according to this embodiment, the lower end 4a of the wire pressing member 4 and the upper end 5a of the wire supporting member 5 are connected.
Are not located on the same vertical line, the stress applied to the electric wire 1 due to external vibration is distributed to the two points of the lower surface end 4a and the upper surface end 5a. The time during which the electric shock occurs is significantly extended, and the performance against the wire breakage can be improved.

[0012]

As is apparent from the above description of the embodiments, the present invention has a structure in which the length of the wire holding member for holding the wire is shorter than the length of the wire supporting member. It is possible to realize an excellent connector that prevents
