Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a socket device to which electrical equipment such as an electromagnetic relay is connected.

[Prior art and its problems]

Conventionally, as shown in FIG. 6, an electrical device 31 such as an electromagnetic relay connected to a socket device 30 is prevented from coming off upward by the elastic pressing force P of a holding piece 33 spanning the top surface 32 of the main body. There is. Locking pieces 34 are formed at both base ends of the holding piece 33, and the locking pieces 34 are removably locked in locking grooves 36 formed on both sides of the socket base 35.

However, in the above configuration, the socket device 3
0, 37, and 38 are arranged adjacent to each other, the adjacent electric devices 39 and 40 become an obstacle to the operation of attaching and detaching the locking piece 34 to and from the locking groove 36.
Replacing the electrical equipment 31 takes time and effort. Further, the holding piece 33 is completely detached from the socket base 35 when replacing the electrical device 31, but the holding piece 33 after detachment is
If they are stored together with other holding pieces in one place, the holding pieces will become entangled with each other, making handling difficult. Furthermore, there is a risk that the detached holding piece may be lost if left unattended.

On the other hand, arm pieces having grooves formed on both sides of the socket base are respectively protruded, and an engagement hole for engaging the arm pieces is formed at the base end of the holding piece of the electrical device, and the arm pieces of the engagement hole are By forming a tongue piece that resiliently locks into the groove when engaged with the socket, the holding piece can be rotated along the outer wall of the socket base while the hook at the tip of the holding piece is displaced outward. For example, a device that allows electrical equipment to be removed from the socket base has already been proposed (Utility Model Application No. 31879/1983).

However, with the above configuration, although it is possible to prevent loss of the holding piece, since the rotation support part of the holding piece with respect to the socket base and the press-contact holding part are located at the same location on the arm piece, it is difficult to rotate the holding piece. Each time, the groove is scraped off by the tongue piece, and there is a risk that the arm piece will be damaged when the hook portion of the stop spring is displaced outward.

[Purpose of invention]

This invention eliminates the drawbacks of the conventional example described above and allows the electrical equipment to be replaced without removing the holding piece from the socket base, and eliminates the need to store the holding piece. It is an object of the present invention to provide a socket device which can prevent loss of pieces and extend its life.

[Structure of the idea]

In order to achieve the above object, this invention consists of a socket base and a holding piece that is attached to the socket base to prevent the electrical equipment attached to the base from coming off. A mounting groove opening into the mounting groove and an elongated storage groove communicating with the mounting groove are formed along the side wall of the base, and a protrusion is formed on one inner wall of the mounting groove, and the holding piece includes: A pressing piece that engages with the top surface of the electrical device at the distal end, and a locking hole that engages with the protrusion of the socket base at the base end, and elasticity that presses against the other inner wall of the mounting groove, which is opposite to one inner wall of the mounting groove. The retaining pieces are formed with their positions shifted from each other, and the locking hole of the retaining piece is fitted into the protrusion, and the elastic piece of the retaining piece is pressed against the other inner wall, so that the retaining piece It is rotatably supported by a socket base.

[Effect of idea]

According to this invention, the holding piece is rotatably supported by a protrusion provided on one inner wall of the mounting groove provided in the socket base, and the holding piece is supported by the elastic piece provided on the holding piece on the other inner wall of the mounting groove. Since it is held in pressure contact with the socket, there is no need to remove the holding piece from the socket body when replacing electrical equipment.Therefore, there is no need to store the holding piece as in the past, and there is no chance of losing the holding piece. It can be prevented. Further, the operation of engaging and disengaging the holding piece from the electrical device is performed at the tip of the holding piece, and the holding piece is rotated and stored in the storage groove formed along the outer wall of the socket base. Even when socket devices are installed side by side in parallel, the holding piece does not get in the way when replacing electrical equipment, and the neighboring electrical equipment does not interfere with the operation of the holding piece. Moreover, since the positions of the rotation support portion and the press-contact holding portion of the holding piece are shifted, damage to the holding piece support portion is less likely to occur, and the life of the device can be extended.
