[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal removing jig used for removing a connection terminal housed and locked in a connector housing.

[0002]

2. Description of the Related Art A conventional terminal removal jig of this type is disclosed, for example, in Japanese Utility Model Laid-Open Publication No. 4-35391. As shown in FIG. 2,
The arm portions 2, 3 are provided with slope portions 4, 5 on the outside thereof, and a step portion 6 is provided on the inside of the tip of one arm portion 2.
Is provided.

When such a terminal removing jig 1 is used, the opposing inner surfaces of the arms 2 and 3 are pushed from the front surface of the connector housing 7 along the outer surfaces of the connection terminals 8 so that the arms 3 are pressed. The outer slope 5 pushes up the connection terminal 8 in a wedge shape to release the engagement by the projection 9. Similarly, arm part 2
The slope portion 4 invades between the connection terminal 8 and the flexible lance 10 to deflect the flexible lance 10 and release the locking by the projection 11. The step 6 engages with the front surface of the connection terminal 8, and pushes the connection terminal 8 to the rear of the connector housing 7.

[0004]

However, in the above-mentioned conventional example, since the opposing inner surfaces of the arms 2 and 3 are pushed along the outer surface of the connection terminal 8, both the arms 2 and 3 are pressed.
3 must be simultaneously inserted between the connector housing 7 and the connection terminal 8 and between the connection terminal 8 and the flexible lance 10, so that a skilled operation is required. Also,
Since the interval between the arms 2 and 3 of the terminal removal jig 1 must be manufactured according to the outer diameter of the connection terminal 8, the versatility is low.

It is an object of the present invention to solve the above-mentioned problems and to provide a terminal removal jig which is easy to handle and has high versatility.

[0006]

According to the present invention, there is provided a terminal removing jig for attaining the above-mentioned object, which disengages a connection terminal engaged with a movable projection and a fixed projection of a connector housing. An arm for inserting the connector into the connector housing to move the movable projection, and a protrusion arranged substantially parallel to the arm and engaged with a front surface of the connection terminal. Having the tip of the arm projecting forward from the projection so that the projection engages with the connection terminal after the arm has released the engagement by the movable projection. It is characterized by.

[0007]

When the arm is pushed into the connector housing, the arm moves the movable projection to release the engagement between the connection terminal and the movable projection, and the projection forms the front surface of the connection terminal. Engages. The engaged projection and the connection terminal are moved together in the vertical direction to release the engagement between the connection terminal and the fixing projection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 shows a terminal removing jig 21 of the present embodiment.
FIG. 2 is a perspective view of the terminal removing jig 21, and FIG. 3 is a partially enlarged side view thereof.

The connector housing 22 has connection terminals 23.
Are housed and locked by a movable projection 24 and a fixed projection 25 provided integrally with the connector housing 23. Here, the movable projection 24 is provided at the base of the movable plate 26 and moves together with the movable plate 26.

On the other hand, the terminal removing jig 21 is composed of a handle 27 made of synthetic resin and a blade 28 made of metal. The blade 28 has a base 29 fixed to the handle 27 and protrudes from the base 29. Arm 3 inserted between connection terminal 23 and movable plate 26
0 and a projection 31 that engages with the connection portion 23 a on the square tube of the connection terminal 23. The arm 30 is formed so as to sufficiently project forward from the protrusion 31, and the arm 30 is inserted into the connector housing 22 before the protrusion 31. The projection 31 is engaged with the connection portion 23a of the connection terminal 23. The tip of the arm 30 is a flat blade 32 so that the arm 30 can be easily inserted between the connection terminal 23 and the movable plate 26. Arm 30
The lower surface is formed as a horizontal surface 34 so as to slide on the surface of the connection terminal 23, and the upper surface of the arm portion 30 is formed as an inclined surface 34 and a bulging surface 35 for bending the movable plate 26 stepwise. The length of the arm 30 is such that the protrusion 31 is connected to the connection portion 23 a of the connection terminal 23.
When it is fitted into the inside, the engagement between the movable protrusion 24 and the connection terminal 23 is completely released.

Using such a terminal removing jig 21,
In order to take out the connection terminals 23 locked in the connector housing 22, as shown in FIG.
The flat blade portion 32 is inserted between the movable plate 26 of the connector housing 22 and the connection terminal 23.

Subsequently, as shown in FIG.
1 is pushed in the direction of arrow A, and the protrusion 31 is fitted into the connection portion 23 a of the connection terminal 23. At this time, the movable plate 26 is pushed up by the swelling surface 35 of the arm 30 and the movable plate 2
The 6 movable projections 24 come off the connection terminals 23.

Next, as shown in FIG.
When prying up in the direction, both the protrusion 31 and the connection terminal 23 are lifted, and the fixing protrusion 25 is detached from the connection terminal 23. When the electric wire 36 is pulled in the direction of arrow C in this state, the connection terminal 23 is pulled out of the connector housing 22.

The terminal removing jig 21 of this embodiment not only releases the engagement between the connector housing 22 and the connection terminal 23 but also releases, for example, the lock between the connector housing (not shown) and the front holder. It can also be used for other purposes.

[0015]

As described above, in the terminal removing jig according to the present invention, after the arm is pushed in to release the engagement by the movable projection, the projection engages with the connection terminal to engage by the fixed projection. , The operation of releasing the engagement by the movable projection and the operation of releasing the engagement by the fixed projection can be performed continuously, and the workability is improved. In addition, since the protrusion only engages with a part of the tip of the connection terminal, it is not affected by the size of the connection terminal, there is almost no dimensional restriction, and versatility is improved.
