Description

[Detailed Description of the Invention] The present invention relates to a terminal block that has a simple structure and can easily and reliably fix terminals to a base.

A conventional terminal block is as shown in Fig. 2, in which a terminal consisting of an upper horizontal part 4, a lower horizontal part 5, and a vertical part 6 is inserted into a chamber 3 formed between a cover 1 and a base 2. A spring-like connector 7 bent in a substantially S-shape was arranged between the two horizontal parts so that each free end 8, 9 was slightly spaced apart from the upper horizontal part 4. 10 is a removal tool, and 11 is a lead wire.

However, the terminal shown in FIG.
It was fixed by fitting it into each small hole. In the case of such a terminal block, since the protrusion 12 has a relatively small diameter, and the cover, base, etc. may be made of synthetic resin, it may break due to impact, etc. If the protrusion breaks, the terminal It could move or fall off, causing poor contact or a major accident.

The object of the present invention is to provide a terminal block in which terminals can be easily and firmly assembled into a chamber formed by a cover and a base, and the terminals will not fall off after being assembled.

The present invention has been devised to achieve the above object. According to the present invention, an elastic engagement piece is provided on the lower surface of the lower horizontal portion of the terminal, which is inclined toward the base, and is engaged with the upper surface of the base. A recess is provided corresponding to the mating piece, and the locking piece locks at the same time as the terminal is inserted into the locking portion formed by the recess.

An embodiment shown in the drawings will be described below. 2
1 indicates a cover and 22 indicates a base. 23 is a chamber formed by the cover and the base. A terminal 24 is inserted into this chamber 23. This terminal is formed by an upper horizontal part 25, a lower horizontal part 26, and a vertical part 27 connecting each horizontal part.

However, an engaging member 28 is provided on the lower surface of the lower horizontal portion 26.
is fixed by an appropriate means, and the engaging piece 29 at the tip thereof is bent with elasticity so as to be spaced apart from the lower horizontal part 26 and inclined toward the base 22 side. An engaging element 30 having a recess is formed at a location of the base 22 corresponding to the engaging piece 24. Therefore, terminal 2
4 is inserted into the chamber 23, the engaging piece 2 of the engaging portion 28
9 elastically locks onto the locking portion 30 of the base 22, so that the terminal 24 will not fall off no matter what kind of impact is applied.

A resilient connector 31 bent in a substantially S-shape is inserted between both horizontal portions of the terminal 24, and its free ends 32, 33 are slightly spaced apart from the lower surface of the upper horizontal portion 25. A lead wire 34 is inserted between the lower side of the upper horizontal portion 25 of the terminal and the connector 31. When this lead wire is inserted as shown, it engages with the edge portion of one free end 32, so that it will not come out even if the lead wire is pulled.

Reference numeral 35 indicates a removal tool inserted into the cover 21. By pressing this, the free end 32 of the connector 31 is disengaged from the lead wire 34 and the edge portion of the free end 32 of the connector 31, and the lead wire is removed. It is something that can be extracted.

In this way, according to the present invention, the terminal 24 has the elastic engagement piece 29 locked in the locking part formed by the recessed part of the base, so the terminal does not fall off due to impact and is strong. However, the terminal can be easily attached to the base.
