Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a socket structure for a relay.

[Background technology]

Conventionally, this type of relay socket structure has multiple blade spring insertion holes drilled in the body in advance to insert the blade spring, and the required blade spring insertion holes are used according to the number of pins of the relay to be installed. However, if the blade spring insertion hole is inserted through the blade support spring insertion hole from the beginning, some of the sealant that seals the opening of the blade support spring insertion hole through which the terminal piece has penetrated may be removed from the unused blade support spring insertion hole. There was a risk that the substance could get inside through the opening of the hole. Therefore, a thin membrane-like blocking wall is formed integrally with the body at the opening to close the opening, and if necessary, the blocking wall at the opening of the blade receiving spring insertion hole can be broken and used. However, in this conventional example, when inserting the blade receiving spring into the blade receiving spring insertion hole, the blocking wall is broken in order to allow the terminal piece provided at the bottom of the blade receiving spring to pass through the opening. The disadvantage is that it requires force and is therefore difficult to insert.

[Purpose of invention]

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to provide a relay socket structure that prevents sealant from entering and has a blade support spring insertion hole that makes it easy to insert the blade support spring. is to provide.

[Disclosure of invention]

The present invention is a blade receiving spring 1 that connects relay terminals.
The body 3 has a plurality of blade receiving spring insertion holes 4 through which the terminal pieces 2 integrally provided on the blade receiving spring 1 are inserted and passed through to the outside of the body 3 made of a resin molded product.
In the relay socket structure drilled in the relay socket structure, a thin blocking wall 5 is integrally provided to protrude from the opposing inner wall surface of each blade receiving spring insertion hole 4 so as to face each other, and the peripheral edge of the blocking wall 5 other than the protruding base and the blade. Between the inner wall surfaces of the receiving spring insertion hole 4 and between the other closing walls 5, a gap 6 of a minute width is provided to prevent the sealant from entering. When inserted from above, the tips of the lower terminal pieces 2 push open the closing walls 5 on both sides and penetrate below the opening.

This will be explained in detail below with reference to embodiment figures. The body 3 is made of a resin molded product, and as shown in FIG. 3, the vertical walls 7 on both sides hold down the cover of a relay (not shown) mounted on both sides and are locked with locking claws 8 provided at the top end. A plurality of pairs of blade receiving spring insertion holes 4 for inserting the blade receiving spring 1 are opened in parallel on the upper surface of the body 3. As shown in FIG. 1, the blade receiving spring insertion hole 4 has an opening at the bottom for passing the terminal piece 2 formed integrally with the lower part of the blade receiving spring insertion hole 4.
In this opening, as shown in FIG. 2, thin blocking walls 5 are integrally provided to protrude from the inner wall surfaces of both ends of the blade receiving spring insertion hole 4 perpendicular to the width direction of the terminal piece 2 so as to face each other. Both of the closing walls 5 close the bottom opening. A gap 6 is provided between both side edges of each closing wall 5 and both inner wall surfaces of the blade receiving spring insertion hole 4 and between opposing edges of both closing walls 5, so that both closing walls 5 are provided with a protruding base. It can be opened using the hinge. Further, the width of each gap 6 is so small that the sealant cannot penetrate.

When the blade receiving spring 1 is inserted into the blade receiving spring insertion hole 4 from the upper surface opening, the terminal piece 2 at the bottom of the blade receiving spring 1 is inserted into the gap 6 between the opposite edges of both the closing walls 5 of the insertion hole 4. Penetration can be easily achieved by cutting in and pushing open both closing walls 5 downward as shown in FIG.

Furthermore, when the concave surface 9 provided to surround the opening of the blade receiving spring insertion hole 4 at the bottom of the body 3 is filled with a sealant, the opening of the blade receiving spring insertion hole 4 that is not in use is blocked by the closing wall 5. Moreover, since the gap 6 is minute, it is possible to prevent the sealant from entering.

[Effect of idea]

In the present invention, a thin wall is integrally protruded from the opposing inner wall surface of each blade receiving spring insertion hole, so that it can be used to seal the protruding part of the terminal piece of the blade receiving spring with a sealant. Even if the sealant flows into the blade receiving spring insertion hole in use, or even if the opening surface is sealed in the same way, it is blocked by the closing wall, so it can be prevented from flowing into the blade receiving spring insertion hole. Moreover, since there is a space between the periphery of the blocking wall other than the protruding base and the inner wall surface of the blade receiving spring insertion hole and between other blocking walls, the blocking wall can be pushed open due to the gap, and therefore the terminal can be opened. The closing wall can be pushed open when the piece is penetrated, making it easy to insert the blade receiver spring, and the gap is narrow enough to prevent sealant from entering, so when not in use, the sealant can be applied from the gap to the blade receiver. There is no possibility of intrusion through the insertion hole.
