Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector from which a connecting wire can be removed with a small removal force.

Conventionally, a connector of this type as shown in FIG. 1 has been known. In the connector shown in FIG. 1, the connection wire insertion port 2 of the connector housing 1 is
When removing the connecting wire 5 which is pressed and held between one side wall 3 and the contact spring 4, the pressure slider 7 press-fitted between the other side wall 6 and the contact spring 4 is slid in the direction of the arrow in the figure. By doing so,
The force with which the contact spring 4 presses the core wire 8 of the connecting wire 5 is weakened or released, and the wire is removed. Since the pressure welding slider 7 is structured to slide upward in this way, the pressure welding slider 7 and the connector housing 1
Not only does this complicate the connection structure, but it also requires a space above the connector housing 1 to allow the pressure welding slider 7 to slide, and it cannot be used in devices where space is limited in the height direction. There were drawbacks such as:

The present invention was developed in view of the above-mentioned points, and one side wall of the connection wire insertion opening of the connector housing is formed into a slider that can be slid laterally along the side wall surface, and the inner wall surface of the slider is By drilling a loose fit groove into which the core wire of the connecting wire loosely fits when the slider slides, when the connecting wire is removed,
By sliding the slider, the core wire of the connecting wire is loosely fitted into the loosely fitting groove, and can be removed with a small force. This simplifies the structure and reduces the overall height of the connector, allowing it to be used in devices with limited space in the height direction.

Hereinafter, one embodiment of the present invention will be described using the drawings from FIG. 2 to FIG. 6.

FIGS. 2 and 3 show the connection wire being inserted, and in the figures, 9 is a connector housing molded from an insulating material such as synthetic resin. The connector housing 9 has a main body 13 having a guide groove 11 formed on one side plate 10 and a guide hole 12 formed in the side plate 10, and is fitted into the guide groove 11 of this main body 13 for connection. A slider 15 forms one side wall of the wire insertion port 14. The slider 15 has a protrusion 16 protruding from the outer wall surface of the slider 15 to fit loosely into the guide hole 12, and extends laterally along the guide groove 11. It is constructed so that it can slide back and forth within a predetermined range. In the inner wall surface of the slider 15, vertical grooves 18, 18, 18 are formed at predetermined intervals for loosely fitting the core wire 8 of the connecting electric wire 5. A contact housing hole 19 is formed in the main body 13, and a contact spring 20 is housed in the contact housing hole 19. As shown in FIG. 4, the contact spring 20 is made by bending a conductive rectangular plate into a substantially C-shape, using the upper part as a leaf spring-like contact 21, and cutting and bending the center part. The leg portions 22 are made to protrude from the bottom. The contact spring 20 has its leg portion 22 connected to the main body 13.
The plate spring-like contact 21 and the back and side parts are fixed to the bottom plate of the contact receiving hole 1.
The leaf spring-like contactor 20 is configured such that the tip end thereof presses the inner wall surface of the slider 15 with elastic force.

In FIG. 3, when the connecting wire 5 is inserted through the connecting wire insertion opening 14 of the main body 13, the core wire 8 is inserted into the tip of the leaf spring-like contact 21 of the contact spring 20, as shown by the chain line in the same figure. and slider 1
The core wire 8 is press-fitted between the flat inner wall surface of the plate spring contact 21 and the core wire 8
Pressed and clamped. This results in a predetermined connection state.

Next, the case where the connecting wire inserted and connected as described above is removed will be explained using FIG. 5 and FIG. 6. As shown in FIG. 5, when the slider 15 is pressed in the direction of the arrow, the protrusion 1
6 is guided in the guide hole 12, the slider 15 slides laterally along its side wall surface, and comes to a position where the loose fitting grooves 18, 18 on the inner wall surface face the contact receiving hole 19. The core wire 8 of the connecting electric wire 5 is loosely fitted into the loosely fitting grooves 18, 18. Therefore, the connecting wire 5 can be removed with a small force. After removal, when the slider 15 is pressed in the opposite direction, it returns to the state shown in FIG. 2, and the loose fitting grooves 18, 18 are displaced from the positions facing the contact receiving holes 19, 19. Then, the state becomes ready for insertion of the above-mentioned connecting wire.

As described above, in the connector according to the present invention, one side wall of the connection wire insertion port of the connector housing is formed into a slider that can be slid laterally along the side wall surface, and the inner wall surface of this slider is used for connection. By drilling a loose fitting groove into which the core wire of the electric wire is loosely fitted,
The connecting wire can be removed with a small amount of force.
Therefore, the structure of the connector is simplified and its height is reduced, so that it can be used in devices that do not require space in the height direction.
