Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a relay socket having a structure to prevent the relay body from coming off when the relay body is attached.

[Background technology]

Conventionally, as shown in Fig. 3, side pieces 2, 2 of a molded product were integrally erected from the upper surface of the side edge of the socket body 1, and these side pieces 2, 2 were attached to the socket body 1. It is arranged to face the relay main body 3 along the side surface thereof. From the top of the side vertical piece 2, there is a downward tongue piece 4 that is integrally inclined slightly toward the relay main body 3.
When the relay main body 3 is attached to the socket main body 1, the locking claw 6 at the lower end of the downward tongue piece 4 is engaged with the protrusion 5 at the lower side of the relay main body 3, and the relay main body 3 is extended. It is designed to prevent it from coming off.

However, in the conventional example described above, when removing the relay body 3 from the socket body 1,
As shown by the broken line in the figure, push the upper part of the side upright piece 2 toward the relay body 3 side, rotate the downward tongue piece 4 using the protrusion 7 provided at the center of the side surface of the relay body 3 of the downward tongue piece 4 as a fulcrum, It is necessary to disengage the locking pawl 6 and the protrusion 5, and at the same time when removing and removing the relay body 3, it is necessary to keep pressing the side stand piece 2 as described above, which reduces work efficiency. I had a bad problem.

[Purpose of invention]

The present invention has been proposed in view of the above-mentioned points, and the engagement between the locking pawl and the protrusion can be disengaged by simply pushing the side piece once, and the relay body can be removed and removed with one hand. It is an object of the present invention to provide a relay socket that is easy to use and has improved workability.

[Disclosure of invention]

FIG. 1 shows an overall perspective view of the embodiment of the present invention, and FIGS. 2a and 2b show the state in which the relay main body 3 is installed with the locking claw 6 and the projection 5 engaged, and the state in which the locking claw 6 and the projection 5 are attached, respectively.
FIG. 2 is an enlarged cross-sectional view of the main part of the relay body 3 in a state immediately before being removed and disengaged from the relay body 3; A downward tongue piece 4 is provided on the side vertical piece 2, and the lower end of this downward tongue piece 4 is used as a locking claw 6 to engage with a protrusion 5 on the side of the relay body 3 to prevent the relay body 3 from coming off. The structure is similar to the conventional example described above. Furthermore, in the present invention, an engagement protrusion 8 protruding toward the relay main body 3 is provided at the upper and lower intermediate position of the downward tongue piece 4, and the engagement protrusion 8 is formed into a sawtooth shape with an inclined surface on the lower surface side. The upper surface of the engagement protrusion 8 is adapted to be hooked into a notch 9 on the side of the relay main body 3, which will be described later. Relay body 3
A notch 9 is formed on the side surface at a position slightly below the position corresponding to the engaging protrusion 8, and when the side vertical piece 2 is pressed and bent toward the relay main body 3, the engaging protrusion 8 is inserted into the notch. 9.

Thus, in the above embodiment, the socket body 1
When inserting the relay body 3 into the relay body 3, the procedure is exactly the same as in the conventional example, and the relay body 3 is inserted as shown in Fig. 2a.
The protrusion 5 and the locking claw 6 of the downward tongue piece 4 are locked, but when removing the relay main body 3, the upper part of the side vertical piece 2 is moved toward the relay main body 3 side as shown in Fig. 2b. The engaging protrusion 8 of the downward tongue piece 4 is engaged with the notch 9 of the relay body 3, and as a result, the engagement between the protrusion 5 and the locking pawl 6 is disengaged, preventing the relay body 3 from being removed. You will be able to do it.

[Effect of idea]

As mentioned above, the present invention has an engaging protrusion at the upper and lower intermediate parts of the downward tongue piece, and a notch on the side of the relay body at a slightly lower position corresponding to the engaging protrusion. When the upper part is pressed and bent toward the relay body against its elasticity, the engaging protrusion engages with the upper edge of the notch on the relay body side, thereby releasing the engagement between the locking pawl and the protrusion. This eliminates the need to keep pressing the side stand piece while removing and removing the relay body, and the relay body can be easily removed with one hand, greatly improving work efficiency. This has the effect of

[Brief explanation of drawings]

Fig. 1 is an overall perspective view of an embodiment of the present invention, Fig. 2 is an explanatory view showing an enlarged cross-section of the main parts to explain the states of locking and releasing the relay main body to the socket main body, and Fig. 3 The figure is an enlarged sectional view of main parts of a conventional example, in which 2 is a side upright piece, 3 is a relay body, 4 is a downward tongue piece, 5 is a protrusion, 6 is a locking pawl, 8 is an engaging protrusion, 9
is the notch.

Claims (1)

[Scope of utility model registration request] A downward tongue piece is extended from the upper part of the side vertical piece that stands along the side surface of the relay body when the socket is attached, and the lower end of this downward tongue piece is used as a locking claw on the upper surface of the protrusion on the lower side of the relay body. In a relay socket configured to lock and prevent from coming off,
An engaging protrusion protruding toward the relay body is provided at the upper and lower intermediate portions of the downward tongue piece, and a notch is provided at a slightly lower position corresponding to the engaging protrusion on the side of the relay body, so that the side vertical piece resists the elasticity of the engaging protrusion. When the socket is pressed and bent, the engaging protrusion engages with the upper edge of the notch and the engagement between the locking pawl and the protrusion is released.
