Abstract

PURPOSE:To make easy the connection of the metalic terminal parts on the lower section of a terminal rack to conductors even when the connection of the metalic terminal parts on the upper section to conductors is performed previously by constructing the said two sections separately and combining them to be slidable so that the terminals of the lower section can be moved close to or away from the terminals on the upper section. CONSTITUTION:The both sides of a base 3 is constructed with an upper section 31 and a lower section 32, and the metalic terminal parts 1, 2 are provided on the two sections respectively and connected to a socket with inner lead wires 6. The sections 31 and 32 are constructed with separate members 3a and 3b respectively, and a guide groove 8 is provided on the member 3a, and a guide bar 7 is provided on the member 3b made to be slidable. Therefore even when the connection of conductors to the terminals 2 on the lower section is hard for the sake of previous connection of conductors to the terminals 1 on the upper section, by sliding the member 3b the upper and the lower section can be kept at a distance to connect conductors to the terminals 2. Thus by making it possible to move the lower section close to or away from the upper section the connection of conductors to the said metalic parts can be made easy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a terminal block used for connecting a relay or the like to a printed circuit board.

[Background technology]

For example, when connecting a relay etc. to a printed circuit board,
Rather than connecting relays directly to a printed circuit board, such as by soldering, it is common to connect them through a removable terminal block. However, it is convenient to be able to immediately replace a malfunctioning relay.

FIG. 5 shows an example of the relay terminal block.As shown in FIG. It is set up in two tiers. Conventionally, two stages like this (
For multi-stage) type terminal blocks, as shown in Figure 6,
If the conductor 4 is connected to the upper terminal fitting 1 first, even if it becomes necessary to connect the wire to the lower terminal fitting 2 later, the conductor 4 that was connected earlier will get in the way and will not be able to connect, and the conductor will not be able to connect. 4, the lower terminal fitting 2 must be connected, and the upper terminal fitting 1 must be reconnected again.

[Purpose of the invention]

In view of the above circumstances, it is an object of the present invention to provide a terminal block that allows easy connection of lower terminal fittings even if they are connected to upper terminal fittings.

[Disclosure of the invention]

In order to achieve the above object, the present invention provides a terminal block in which terminal fittings for connecting conductor wires are provided in multiple stages on a step-like portion of a base, in which the portion where each stage of terminal fittings is provided is The terminal block is characterized in that each member is a separate member, and the lower member can be moved relative to the upper member so that the lower terminal member can be moved into and out of contact with the upper terminal member. This is the summary.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 and FIG. 2 each show an embodiment of the terminal block according to the present invention. As shown in the figure, this terminal block is a terminal block for a relay, and includes a base 3 having an insertion hole 5 for a relay terminal on its upper surface. Inside this base 3, although not shown, there is a socket connected to the relay terminal, and by connecting the relay terminal to the socket through the insertion hole 5, the relay can be connected to this terminal block. It is meant to be combined. base 3
Both sides are shaped like steps. That part 31.3
2 supports terminal fittings 1.2 for connecting conductive wires, respectively. Thereby, the terminal fittings 1.2 are provided in two stages. The socket and the terminal fitting 1.2 are connected by an internal wiring 6. The upper part 31 and the lower part 32 are provided on separate members 3a and 3b.

A guide bar 7 is provided on the lower member 3b in which the lower portion 32 is provided. On the other hand, a guide groove 8 is formed in the upper member 3a in which the upper part 31 is provided. The guide bar 7 is fitted into the guide groove 8 and is slidable along the guide groove 8. This results in
The lower member 3b can be slid in the direction of the arrow with respect to the upper member 3a, so that the lower terminal fitting 2 can be moved away from or closer to the upper terminal fitting 1. In other words, as shown in Figure 1,
The upper terminal fitting 1 and the lower terminal fitting 2 can be brought closer to each other, or the upper terminal fitting 1 and the lower terminal fitting 2 can be moved apart as shown in FIG.

Since this terminal block is configured as described above, the third
As shown in the figure, even if the conductor 4 is connected to the upper terminal fitting 1 first, the lower member 3b is slid relative to the upper member 3a to separate the upper terminal fitting l and the lower terminal fitting 2. Then, the lower terminal fittings 2 can be connected by simply bending the previously connected conductive wires 4 slightly and shifting them laterally. Therefore, there is no need to temporarily remove the conductive wire 4 connected to the upper terminal fitting 1 and reconnect it again, unlike in the conventional case, and the connection can be easily performed.

In addition, when using the above configuration, the lower terminal fitting 2
It is necessary to make the internal wiring 6 connected to the internal wiring 6 a little longer than the conventional one to allow for sliding.Also, in the state shown in Fig. 1, make sure that the lower member 3b does not easily move relative to the upper member 3a. It is preferable to keep it.

FIG. 4 shows another embodiment. As shown in the figure, this terminal block has an upper member 3a and a lower member 3b.
is removable. A pin 61 connected to the lower terminal fitting 2 projects from the lower member 3b toward the upper member 3a. In the figure, from the upper member 3a to the lower member 3
b is showing signs of being weaned. From this state, the pin 61 is connected to the two terminal springs 62 provided on the upper member 3a.
When inserted between them, the lower member 3b is joined to the upper member 3a, resulting in the same state as in FIG. The terminal spring 62 is connected to a socket that is connected to the relay terminal, and by inserting the pin 61, a connection is made between the socket and the lower terminal fitting 2.

In this way, even in the case of a removable type, the lower member 3
By simply separating b from the upper member 3a, the lower terminal fitting 2
Wiring work can be done easily. In addition, if the required number of terminals (required number of terminal fittings) is small, remove the lower member 3b from the upper member 3a and remove the lower member 3b from the upper member 3a.
If only a is used, and if a large number of terminals are required, the lower member 3b may be attached to the upper member 3a and both may be used. If the terminal is removable in this way, additional terminal fittings can be easily added.

The terminal block according to the present invention is not limited to the embodiments described above. In the above embodiment, a terminal block for a relay is shown, but it may be a terminal block for other electrical or electronic components. The number of stages of the terminal fittings is not limited to two stages, but may be three or more stages. The movement of the lower member relative to the upper member may be a movement in a direction different from the arrow direction, such as a movement in a direction perpendicular to the arrow direction shown in FIGS. 1 and 2. Further, the lower member may be configured to rotate relative to the upper member. In short, it is sufficient that the lower member is movable relative to the upper member so that the lower terminal metal fitting can be moved into and out of contact with the upper terminal metal fitting.

〔Effect of the invention〕

As seen above, in the terminal block according to the present invention, the portion where the terminal fittings of each stage are provided is a separate member,
The feature is that the lower member can be moved relative to the upper member so that the lower terminal member can be moved into and out of contact with the upper terminal member, so even if wires are connected to the upper terminal member, , the lower terminal fittings can be easily connected.
