Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a socket, particularly a socket for mounting a control device such as a relay.

Usually, this type of socket includes a receiving metal fitting into which a connection terminal of a control device can be press-fitted, and an external connection terminal electrically connected to the receiving metal fitting.

Conventionally, the receiving metal fittings and the external connection terminals have been provided, for example, by press working from a single conductive plate and attaching them to the socket body. However, in this case, it is necessary to prepare molds with different shapes depending on their installation positions, which is not compatible and increases the number of types of press molds, which is extremely uneconomical. Furthermore, once an arbitrary electrical connection relationship is determined, it is impossible to change the design of the connection relationship as a special specification.

For this reason, there is also a method in which the two are manufactured separately and the electrical connection is made by soldering a tin wire. However, soldering is inefficient and is not a preferred method.

The present invention was developed in view of these drawbacks, and its purpose is to manufacture the receiving member and the external connection terminal separately to enable compatibility between them, and to
To provide a socket in which the connection can be easily made by caulking and an external connection terminal can be fixed with a simple configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

In Fig. 1, reference numeral 1 denotes a socket body, with a mounting base 2 for control equipment in the center, terminal blocks 4 on both sides,
It is equipped with 4. An insertion hole 3 is provided on the top surface of the mounting base 2.
are drilled to match the octal pin arrangement of the control equipment. Further, the terminal block portion 4 is formed with a hexagonal hole 5 and terminal mounting blocks 6a, 6b, 6c, and 6d.

10 is a terminal for external connection, with a bent piece 11 at one end;
The other end has a bent piece 13 having a protruding piece 12 and a pair of caulking pieces 14 at the lower part.

20 is a fastening bolt, 21 is its washer, 22
is a hexagonal bolt.

Reference numeral 30 denotes a receiving metal fitting, which is approximately cylindrical in shape, and has a pair of caulking pieces 31, 31 formed at its upper part.
The cylindrical shape of the receiving metal fitting 30 corresponds to the fact that the external connection terminal of the control device is an octal pin, and if the external connection terminal is a flat plate, the shape corresponds to that. It is.

The above parts are assembled as follows.

First, as shown in FIG. 2, one end of the lead wire 25 is caulked to the caulking piece 14 of the external connection terminal 10, and the other end is connected to the receiving metal fitting 30 and the external connection terminal 10, which are to be connected internally. Caulk the caulking piece 31 of the metal fitting 30.

Next, the receiving metal fitting 30 is pushed into a predetermined insertion hole 3 from above, and the receiving metal fitting 30 is prevented from coming off by the protrusions 32, 32 engaging with recesses (not shown) in the insertion hole 3. At the same time, the hexagonal nut 22 is press-fitted into the hexagonal hole 5, and the external connection terminal 10 is
on the hexagonal nut 22 and the terminal mounting bases 6a, 6b,
Press fit onto 6c and 6d. At this time, the hole 15 of the external connection terminal 10 is connected to the female thread 2 of the hexagonal nut 22.
3, the protruding piece 12 is located on the terminal mounting base 6c, and the bent piece 11 is located on the groove-shaped terminal mounting base 6d (see FIG. 3).

Next, the tightening bolt 20 is screwed into the female thread 23 of the hexagonal nut 22 through the hole 15 of the external connection terminal 10. After that, cover 35 is put on. At this time, the lower end surfaces of the walls 36 and 37 of the cover 35 press the bent piece 11 and the protruding piece 12 of the external connection terminal 10. That is, the external connection terminal 10 is connected to the bent piece 1.
1. The protruding piece 12 is attached to the terminal mounting base 6 of the socket body 1.
d, 6c and the lower end surfaces of the wall portions 36, 37 of the cover 35 are crimped and fixed.

As is clear from the above explanation, the present invention provides a caulking piece on the receiving metal fitting and the external connection terminal, and connects the two electrically by caulking the lead wire to the caulking piece. It is only necessary to manufacture different types of parts, and it is compatible depending on the installation location, making it extremely economical. Furthermore, caulking can be performed more efficiently than conventional soldering.

In addition, since a part of the external connection terminal placed on the terminal block of the socket body is pressed by the wall of the cover, the external connection terminal can be installed at the same time as the cover is installed, without complicating the structure. can be fixed.
