Abstract

PURPOSE:To reduce the size of the constitution of a terminal block and to facilitate disconnection of wires by freely engaging/separating a terminal block main body and its cover mutually in the same shapes provided with grooves for release operation, lock 9 pawls, locking holes, etc., to/from each other through the locking pawls. CONSTITUTION:Wires are inserted from wire insertion holes 10 into the terminal housing recesses side 3 of a terminal block main body 1 and its cover 2 mutually in the same shapes to be housed therein so that one side locking pawl 8 is engaged with the other side locking hole 9 so as to engage the body 1 with the cover 2. As the body 1 and the cover 2 mutually in the same shapes are used and no release button is necessary, the number of parts is reduced by a half so that the size of the constitution of a terminal block is reduced and wires can easily be disconnected.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal block used for wiring electrical equipment.

0002

2. Description of the Related Art First, a conventional example is shown in FIGS. 3 and 4. A terminal block main body 1 and a cover 2, each made of synthetic resin, are combined. Two terminal accommodating recesses 3 are formed in the terminal block body 1 and the cover 2 at a predetermined interval, and terminals 5 for connecting electric wires 4 wired for each polarity are formed in these terminal accommodating recesses 3. It is stored. As shown in FIG. 4, these terminals 5 have an elastic piece 6 bent at an acute angle and a contact piece 7 opposite to the tip edge of the elastic piece 6 at both ends. The core wire portion of the electric wire 4 is held between them.

0003

[Problems to be Solved by the Invention] Conventional terminal block main body 1 and cover 2 are connected by screws or the like, or a plurality of locking claws are formed on one side of the terminal block and the cover, and a plurality of locking claws are formed on the other side. They are connected by forming holes and engaging these locking claws and the locking holes. Therefore, the terminal block main body and the cover have different shapes, and the number of parts increases. In addition, since the terminal block body 1 and the cover 2 are molded using different molds,
There are problems such as an increase in the number of molds.

0004

[Means for Solving the Problem] A plurality of terminal storage recesses in which terminals are stored, grooves for release operation opened at the bottoms of these terminal storage recesses, and wire insertion holes continuous at both ends of the terminal storage recesses. a terminal block main body and a cover having an opening on one side and having the same dimensions and the same shape, and locking claws provided on both sides of the terminal block main body from a surface facing the cover, and locking claws that are connected to the cover. a locking hole that opens on an opposing surface, and a locking hole that is engaged with the locking claw of the terminal block body and a locking claw that is engaged with the locking hole of the terminal block main body. The cover is formed on a surface facing the terminal block main body.

[0005]

[Operation] The terminal block main body and the cover are connected by engaging the locking claws formed on the opposing surfaces of the two into the locking holes on the other side, but the terminal block main body's terminal storage recess and the cover's In order to store a common terminal with the terminal storage recess, the dimensions and shape of the terminal block main body and the cover, including the groove for release operation and the wire insertion hole, are determined to be the same, and furthermore, the terminal block main body and the cover are Since the terminal block body and the cover have equal locking claws and locking holes, and the locking claws on the terminal block body and the cover are engaged with the locking holes on the other side, the dimensions and shapes of the terminal block body and the cover should be made equal. Therefore, the number of parts can be halved by using the terminal block main body and the cover in common.

[0006]

[Embodiment] An embodiment of the present invention will be explained based on FIGS. 1 and 2. Components that are the same as those described in FIGS. 3 and 4 are designated by the same reference numerals, and description thereof will be omitted. FIG. 1 shows a terminal block main body 1 and a cover 2 with their opposing surfaces facing upward, and the terminal block main body 1 and cover 2 have electric wires connected to both ends of the terminal storage recess 3. An insertion hole 10 and a groove 11 for release operation that opens at the bottom of the terminal storage recess 3 are formed. Furthermore, on both sides of the opposing surfaces of the terminal block main body 1 and the cover 2, two locking claws 8 having exactly the same size and shape are vertically formed. Two locking holes 9 are formed. The terminal block main body 1 and the cover 2 are made of elastic synthetic resin, and the locking pawl 8 is formed to have a thickness that allows it to be elastically bent. Further, the locking claw 8 has a laterally projecting claw portion 8a at its tip, and the locking hole 9 has a stepped portion (not shown) on its inner surface that engages with the claw portion 8a.

In such a structure, the terminal block main body 1 and the cover 2 have opposing surfaces joined to each other by engaging the locking claws 8 formed on the opposing surfaces with the locking holes 9 on the other side. (See Figure 2). In addition, since the terminal storage recess 3 of the terminal block main body 1 and the terminal storage recess 3 of the cover 2 store a common terminal 5, the groove 1 for release operation
1 and the wire insertion hole 10, the terminal block main body 1 and the cover 2
Furthermore, the terminal block main body 1 and the cover 2 have the same locking claws 8 and locking holes 9, and the locking claws 8 of the terminal block main body 1 and the cover 2 have the same size and shape. Since it is engaged with the locking hole 9 on the side, it is possible to make the dimensions and shapes of the terminal block main body 1 and the cover 2 the same. Therefore, it is possible to use the terminal block main body 1 and the cover 2 in common and reduce the number of parts by half.

[0008]

[Effects of the Invention] The present invention provides a plurality of terminal storage recesses in which terminals are stored, a release operation groove opened at the bottom of these terminal storage recesses, and an electric wire insertion hole continuous to both ends of the terminal storage recess. a terminal block main body and a cover having an opening on one side and having the same dimensions and the same shape, and locking claws provided on both sides of the terminal block main body from a surface facing the cover, and locking claws that are connected to the cover. a locking hole that opens on an opposing surface, and a locking hole that is engaged with the locking claw of the terminal block body and a locking claw that is engaged with the locking hole of the terminal block main body. Since the terminal block body and the cover are formed on the surface of the cover facing the terminal block body, the terminal block body and the cover are connected by engaging the locking claws formed on the opposing surfaces of both sides with the locking hole of the other side. However, since the terminal storage recess in the terminal block body and the terminal storage recess in the cover store the same terminal, the dimensions and shapes of the terminal block body and the cover, including the groove for release operation and the wire insertion hole, are the same. Further, the terminal block main body and the cover equally have locking claws and locking holes, and since the locking claws of the terminal block main body and the cover are engaged with the locking holes of the other side, the terminal block The size and shape of the main body and the cover can be made equal, so that the terminal block main body and the cover can be used in common, and the number of parts can be halved.
