Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a terminal block such as a power supply terminal block used in electric equipment.

[Prior Art] FIG. 11 shows a conventional terminal block in which a terminal plate connected to the conductor 13a of the electric wire 13, a locking spring, a release button, and the like are housed inside a body 41. A pair of terminals 42 electrically connected to the internal terminal plate are arranged at one end of the body 41, and a terminal cover 43 is fitted on the upper surfaces of the terminals 42. Wire 1 on the other side of body 41
An electric wire insertion port for inserting the third conductor 13a is provided, and a release button 44 for releasing the conductor 13a by a jig such as a driver 14 is arranged on the upper surface of the body 41. Therefore, since the inserting direction of the electric wire 13 and the electric wire releasing direction are not the same direction, there is a problem that the space is likely to be limited when the electric wire 13 is arranged in the device. Further, although this conventional terminal block is a solder type terminal block, it cannot be directly connected to the printed board, and as shown in FIG.
The lead wire 45 was used to connect the printed circuit board 5 and the printed circuit board 2. There is also a problem that the size is large as a whole.

[Problems to be Solved by the Invention] The present invention has been provided in view of the above-mentioned points, and makes it easy to arrange in a device by making the wire insertion direction and the wire release direction the same, and at the same time, to provide a printed board. (EN) Provided is a terminal block which is directly attached to improve assembly workability.

[Means for Solving the Problems] The present invention provides a terminal plate, a locking spring for elastically contacting the inserted electric wire with the terminal plate, and a release button for releasing the electric wire for releasing the locking of the electric wire by the locking spring. And a body with one side open, and a cover attached to the opening side of this body,
A plug blade integrally formed on the terminal board, having a hole for inserting a lead wire at the tip, protruding the tip outward from the cover and directly attached to the printed board, and fixing to the printed board. It also has a boss formed on both side surfaces of the body so that the tip projects outward from the surface of the cover attached to the opening surface, and also serves as insertion of mounting screws, and other parts of the body other than the opening surface. The electric wire insertion opening and the insertion opening for operating the release button are formed on the same surface.

[Action]

According to the present invention, the boss enables the printed board to stand on its own, and the blade protruding from the cover can be directly attached to the printed board.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
In FIGS. 4 to 4, the terminal block A has an outer shell made up of a body 1 and a cover 15 which are both made of an insulating material, and the body 1 is box-shaped and has one surface open. In the storage recess 1a in the body 1, a conductive and substantially U-shaped terminal plate 2 and a conductor 13a of an electric wire 13 which is arranged in the terminal plate 2 are connected to the terminal plate 2
A locking spring 3 for elastically contacting with, a release button 4 for releasing the connection of the conductor 13a, and the like are housed and arranged. A plug blade 8 is integrally projected from one edge of the terminal plate 2, and a hole 7 for inserting a lead wire is bored in the tip end side of the plug blade 8. Body 1
The bosses 6 are integrally formed on both sides of the opening surface side of
The boss 6 is provided with a screw hole 12 for inserting a screw when it is attached to a case or the like. Further, one surface of the boss 6 (mounting side to the printed board) is a flat surface, and projects toward the opening surface of the body 1. Figure 1 on the top of the body 1
As shown in (a), a pair of electric wire insertion openings 9 for inserting the conductors 13a of the electric wires 13 are formed, and an insertion opening 10 for inserting a jig such as a driver 14 for operating the release button 4 is formed. I am doing it.

A locking piece 16 having elasticity is integrally formed from both sides of the cover 15 that covers the opening surface of the body 1, and a locking hole 17 is formed in the locking piece 16. The side surface of the body 1 on which the locking piece 16 of the cover 15 is located is recessed by one step.
8 are formed respectively, and a projection 19 into which the locking hole 17 of the locking piece 16 is fitted is formed in the recess 18. Further, the cover 15 has a pair of insertion holes 21 through which the blades 8 project.
Is perforated, and an elastic claw 11 for self-supporting the printed board is integrally formed in the central portion. The claws 11 may be provided on both sides of the cover 15, as shown in FIG. Further, as shown in FIG. 7, the blade 8 formed on the terminal plate 2 may be provided with a bent portion 8a for self-support in the middle thereof.

1 and 4 show the state in which the cover 15 is fitted to the body 1. Particularly, as shown in FIGS. 1 (c) and 5, the lower surface of the cover 15 is the lower surface of the boss 6. It is to be fitted into the body 1 so as to be positioned higher, and when the blade 8 is inserted through the printed board 5 and directly connected, the claws 11 of the cover 15 have holes in the printed board 5. The lower surface of the boss 6 contacts the upper surface of the printed board 5, and the boss 6 has a self-standing function (standoff function). FIG. 8 shows a state in which the terminal block A is mounted on the printed board 5, and FIG. 9 shows the terminal block A on the protrusion 23 of the case 22.
The blade 8 is directly attached to the printed board 5. In this case, the boss 6 of the terminal block A is placed on the protrusion 23, and the screw 24 is inserted into the screw hole 12 of the boss 6 and fixed to the protrusion 23.

FIG. 10 shows the terminal block A in the case 22 with screws 24 and nuts 2.
5, the lead wire 26 is inserted and wound around the hole 7 of the blade 8 protruding from the cover 15, and further soldered and connected (hatched in the figure).
Therefore, the blade 8 serves both as a direct attachment to the printed board 5 and a connection with the lead wire 26.

[Advantages of the Invention] As described above, the present invention provides a terminal plate, a locking spring for elastically contacting the inserted electric wire with the terminal plate, and a release button for releasing the electric wire for releasing the locking of the electric wire by the locking spring. And a cover having one surface opened, a cover attached to the opening surface side of the body, and a terminal plate integrally formed with the terminal plate. A blade that protrudes outward from the cover and is directly attached to the printed board,
The opening is provided with bosses formed on both side surfaces of the body so as to project outwardly from the surface of the cover adhered to the opening surface, both for fixing to the printed circuit board and for attaching and mounting screws. Since the wire insertion port and the insertion port for the release button are formed on the same surface as the other surface of the body other than the surface, the boss enables self-standing on the printed board and the blade protruding from the cover. Can be directly attached to the printed board, and moreover, since it can be self-standing on the printed board by the boss, it is easy to assemble into a device, and there is an effect that assembly workability is improved. By forming the wire insertion port and the insertion port for the release button operation on the other surface of the body other than the opening surface and on the same surface so that the wire insertion direction and the wire release direction are the same, The effect that it is easy to place Is shall. In addition, the number of parts is small, and it is small and can be formed at low cost.
