Abstract

PURPOSE:To facilitate maintenance by exposing a terminal at the outer side face of a relay body which is in slide contact with the inner side face of a socket, putting the terminal in pressure contact with this inner side face of socket, and furnishing a contacting part to support the relay body. CONSTITUTION:A relay body 2 is located with respect to a socket 1 fitted on a supporting rail and pressure fitted along the inner side face of supporting walls 11, 11. This socket 1 and relay body 2 are electrically connected only by putting a contacting part 12 and a terminal 22 in pressure contact while the socket 1 bears the relay body 2 removably, to enable fitting and removal by a signal action. This simplifies replacement in the event of trouble and removal/fitting at the time of inspection. Thus the maintenance is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a relay comprising a socket portion and a relay body that can be attached to and detached from the socket portion.

BACKGROUND ART Conventionally, as relays, there are, for example, those mounted on a printed circuit board, or those that are slidably fitted onto a support rail and are arranged in a row in plurality.

However, in the former case, since it is attached to a printed circuit board via solder, it takes time and effort to remove and attach it in case of failure or inspection, and maintenance is troublesome.

On the other hand, with the latter, for example, if you try to replace a faulty relay located at one end of multiple relays installed in a row, it is necessary to slide all the relays out from the other end; Similarly, maintenance was troublesome.

In order to solve the above-mentioned problems, the present invention includes a socket part,
In a relay comprising a relay body that is removably attached in sliding contact with the inner surface of the socket portion, the terminal portion is exposed from the outer surface of the relay body that slides in contact with the inner surface of the socket portion, and A contact portion is provided on the inner surface to press into contact with the terminal portion and support the relay body.

Operation and Effect Therefore, according to the present invention, the terminal portion is exposed on the sliding contact portion of the relay body, and the contact portion that presses against the terminal portion and supports the relay body is provided on the sliding contact surface of the socket portion. Since it is a built-in device, the socket part and the relay body can be connected and separated in two with a single touch.

Therefore, when the relay breaks down or when the relay is to be inspected, it is only necessary to remove the relay body, which has the effect of facilitating maintenance.

Embodiments of the present invention will be described below with reference to the accompanying drawings shown in FIGS. 1 and 2.

As shown in FIG. 1, the relay according to the first embodiment is composed of a socket part l and a relay body 2.

The socket part 1 has a pair of supporting walls t1.11 in a U-shape on the upper surface facing each other, and the supporting walls 11.11 have end parts 11a and 11 located at both ends thereof.
Contact portions 12, 12 are exposed on the opposing inner surfaces of a, respectively. The contact portions 12.12 are connected to external connection portions 13.13, respectively.

Furthermore, the socket part has a fitting part (not shown) on its lower surface that can be slidably fitted to a support rail (not shown).

The relay main body 2 has a planar shape that can be press-fitted from above between the support walls t 1, 1 t, and the contact is formed on the outer surface of a notch 21 formed by cutting out a side corner in the vertical direction. The terminal portion 22 which can be press-contacted to the portion 12 is exposed.

Therefore, according to this embodiment, after positioning the relay body 2 with respect to the socket part l attached to the support rail (not shown), the relay body 2 is press-fitted along the inner surface of the support wall 11.11. By simply bringing the contact part 12 and the terminal part 22 into pressure contact, the socket part 1 and the relay body 2 are electrically connected, and the socket part 1 detachably supports the relay body 2, so that it can be attached and detached with one touch. .

Therefore, replacement work in the event of a failure, removal and installation work during inspection become easier, and maintenance becomes easier.

This is particularly effective when mounting a relay on a printed circuit board via solder, or when a plurality of relays are slidably fitted onto a support rail and are arranged in parallel.

Further, according to this embodiment, the socket part l and the relay body 2
Since the sides of the relays are almost flush with each other and there are no gaps between adjacent relays, there is an advantage of high integration density.

As shown in FIG. 2, the second embodiment differs from the first embodiment in that it has a notch 2 located at the corner of the relay body 2! In contrast to the case where the terminal portion 22 is exposed, this is the case where the terminal portion 22 is exposed from the opposing side end surfaces of the relay body 2.

A contact portion 12.1 that can be press-contacted to the terminal portion 22 is provided on the inner surface of the opposing support wall 11.1 of the socket portion 1.
2 is provided.

The rest is the same as the previous embodiment, so the explanation will be omitted.

In addition, although the above-mentioned Example demonstrated the case where it mounted on the support rail, it is not necessarily limited to this, and the terminal may be made to protrude from the lower surface of the socket part and can be mounted on a printed circuit board.

Further, by providing a connecting portion connectable to another socket portion adjacent to the side surface of the socket portion, there is an advantage that a plurality of relays can be easily connected and unitized.
