Problems solved by technology

[0005] However, in the conventional wire connection completion display mechanism, since it is necessary to newly add two components, the display member H2 and the coil spring H3, and to form a space for accommodating these two components in the main body of the device, there is a problem that The increase in the number of parts and the change in the design of the main body of the device lead to an increase in cost
Also, in the conventional mechanism, since the wire connection completion is visually displayed, there is a problem that it cannot be externally determined whether the wire connection is completed when the display part is invisible

[0099] The quick connect terminal device according to the present embodiment includes a terminal board 1 and a release lever 30 as shown in FIGS. 1 to 3 . As shown in Figure 2, the terminal board 1 has: a rectangular main piece 2; a pair of contact pieces 3 extending vertically downward from one edge of the main piece 2 along its longitudinal direction; A pair of J-shaped locking pieces 4 extending vertically downward along its longitudinal direction. The main piece 2, the contact piece 3 and the locking piece 4 are integrally formed by processing a strip-shaped elastic metal plate, so that the front ends of the contact piece 3 and the locking piece 4 cross each other. Each contact piece 3 has: a pair of pressing parts 3a and 3b that press the two ends of the wire along the insertion direction of the wire; a hook-shaped part 6 formed by bending the front end of the upper pressing part 3b in the direction away from the locking piece 4; And the opening 5 for passing the wire. ...

[0107] The quick connect terminal device according to the present embodiment will now be described with reference to FIGS. 5 to 13 . Components common to the first embodiment are denoted by the same reference numerals, and description and illustration thereof are appropriately omitted.

[0108] In the terminal board 1 according to the present embodiment, as shown in FIGS. Two parts other than the central part of the lock part 4a serve as the receiving part 4c.

[0109] On the other hand, as shown in FIGS. 7 and 8 , the release lever 30 according to the present embodiment includes a second pressing and moving portion 38 opposite to the pressing and moving portion 33 , wherein the contact piece 3 is interposed between the pressing and moving portion 33 and the moving portion 33 . Between the second pressing and moving part 38; The second pressing and moving part 38 is connected to the second connection part 39 of the operation part 31; the second arm portion 40 ; and the hook ...

no. 3 approach

[0114] Although the connection structure between the terminal board 1 and other conductive members (the contact point of the switch or the knife-edge support of the electrical socket) is not particularly described in the first and second embodiments, it is preferable that the terminal board 1 and other conductive members be processed Formed integrally from sheet metal. However, in the first and second embodiments, since the terminal plate and the lock spring are integrally formed, a mold with a very complicated shape is required to integrate the additional conductive member. In order to avoid complicated molds, the terminal board and the other conductive members should be connected using caulking or welding methods.

[0115] Therefore, in the present embodiment, as shown in FIG. 14( a ) and FIG. 15 , by removing the locking piece 4 from the terminal board 1 and having a U-shaped spring piece 10a made of an elastic metal plate and the spring piece 10a The locking spring 10 of ...

Abstract

Provided is a quick connection terminal device in which connection completion indication of an electric wire can be ascertained not only visually but also aurally and, at the same time, increase of the number of components is suppressed. An operating part 31 of a release lever 30 moves to the position lower than the initial position when connection of a terminal plate 1 and the electric wire 110 is completed, by the above, indication of connection completion of the electric wire can be ascertained visually. Also it can be ascertained aurally by the sound (collision sound) which is generated when the operating part 31 collides with the surface of the device body 100. Furthermore, the increase of the number of parts can be restrained by using the release lever 30 for releasing the connection of the electric wire 110 as the indication of connection completion of the electric wire 110 concurrently.

Description

technical field [0001] The invention relates to a quick connection terminal device. Background technique [0002] Conventionally, wiring mechanisms such as electric switches and electric sockets widely use quick-connect terminal devices for connecting wires inserted into a device body through wire insertion holes formed in the device body. This type of quick-connect terminal device is well known and includes: a terminal block electrically connected to the switch contacts; a knife-edge bearing or similar structure for an electrical socket; a locking spring that clamps and supporting wires (conductors), cooperating with the terminal board to electrically connect the wires to the terminal board, and fixing the wires so as to prevent the wires from falling out; Operate and release the fixation with the lock spring (for example, see Patent Document 1). [0003] However, in the conventional quick-connect terminal device, since it cannot be seen from the outside whether the wire ...
