Abstract

(57) [Summary] [Purpose] To obtain an auxiliary relay that can shorten the installation work time. [Structure] Protrusions protruding from the side surface and recesses into which the protrusions can be inserted are provided on both sides perpendicular to the mounting surface of the relay.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an auxiliary relay that facilitates installation work.

[0002]

[Prior Art]

 FIG. 3 is a perspective view showing the attachment of a conventional auxiliary relay. In the figure, 1 is a supplementary auxiliary relay, 1a is a mounting hole provided in a mounting foot of the auxiliary relay 1, and 2 is an equipment attachment to which the auxiliary relay 1 is attached. The panel 3 is a fixing screw which is inserted into the mounting hole 1 a and fixes the auxiliary relay 1 to the device mounting panel 2.

Next, the operation will be described. As shown in FIG. 3, the auxiliary relays 1 are individually attached with fixing screws 3 which are inserted into the mounting holes 1a.

[0004]

[Problems to be solved by the device]

 Since the conventional auxiliary relay is configured as described above, it is necessary to individually mount the device mounting panel 2, and since the number of auxiliary relays 1 used is large, there is a problem that the mounting time is long.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to obtain an auxiliary relay that can shorten the installation work time.

[0006]

[Means for Solving the Problems]

 The auxiliary relay according to the present invention is provided with a convex portion projecting from the side surface and a concave portion into which the convex portion can be inserted, on both sides perpendicular to the mounting surface of the relay.

[0007]

[Action]

 In the auxiliary relay according to the present invention, the convex portions formed on both sides of the adjacent auxiliary relays can be inserted into the concave portions.

[0008]

【Example】

 Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. 1 is a perspective view showing the structure of an auxiliary relay according to Embodiment 1 of the present invention. In the figure, 4 is a substantially rectangular auxiliary relay, 5 is a pair of convex portions projecting at symmetrical positions on both sides of the auxiliary relay 4, 5a is a mounting hole provided in the convex portion 5, and 6 is an auxiliary relay 4 A pair of concave portions provided at symmetrical positions on both sides of the convex portion are configured to have a size such that the convex portion can be inserted.

Next, the operation will be described. As shown in FIG. 2, when a plurality of auxiliary relays 4 are attached to the panel 2, the convex portion 5 of one auxiliary relay 4a is in the concave portion 6 of the other auxiliary relay 4b, and the concave portion 6 of the one auxiliary relay 4a is the other. It is connected to the concave portion 6 and the convex portion 5 so that the convex portion of the auxiliary relay 5b is inserted, and the fixing screw 3 is inserted into the mounting holes 5a and 5a of the convex portions 5 and 5 at both ends and fixed to the mounting panel 2. To do.

Example 2. Although the concave portion and the convex portion are provided on one of the side surfaces of the auxiliary relay in the first embodiment, either the concave portion or the convex portion may be provided depending on the size of the auxiliary relay.

[0011]

[Effect of the device]

 As described above, according to the present invention, the convex portion protruding from the side surface and the concave portion into which the convex portion can be inserted are provided on both sides perpendicular to the mounting surface of the relay, so that the installation work time can be shortened. Is obtained.
