It is made of a metal wire having elasticity.

FIG. 4B is a perspective view of the fusion plate 69 used in the present invention. The slide lock 30, slide knob 20, and fusion plate 69 are all thermoplastic synthetic resin molded products.

Assembly will be described with reference to FIG. 5 with the above configuration. 5A is a perspective view assembled in the state of FIG. 1B, and FIG. 5B is a side sectional view thereof.

First, the coiled portion 66 of the spring 65 is fitted on the shaft 58 of the slide lock 30. Since the inner diameter of the coiled portion 66 is only slightly larger than that of the shaft 58, the coiled portion 66 is deformed by moving the projecting portion 59 toward the groove 60,
The coiled portion 66 can be passed. The fitted spring 65 does not easily come off the shaft 58 due to the return of the overhanging portion 59.

Then, the slide lock 30 is moved closer to the partition wall 47 by bringing the surface of the spring 65 closer to the inner surface of the housing 25 and fitting the notch 54 into the bent portion 46 of the guide 45. Let Guide 45
Since the space between them is exactly the width of the thick plate portion 51 of the slide lock 30, the space can be easily moved without rattling. At the same time when the lock claw portion 19 is inserted into the hole 48 of the partition wall 47, the step portion 55 slides under the bent portion 46.

As shown in FIG. 3B, the spring 65 has a thin plate portion 5 which is different from the thick housing portion 51 of the slide lock 30.
It is located between the surface 2 and the surface of the housing 25 and fits in this space.
On the other hand, the leg portion 67 of the spring 65 is expanded and applied to the support wall 49. As a result, the slide lock 30 is pressed toward the partition wall 47 by the restoring force of the spring 65, but its position is regulated by the end surface of the thick plate portion 51. The lock claw portion 19 is in a state of protruding by a predetermined amount into the power battery attachment portion 15.

In this state, the through hole 4 is provided on the rear side of the housing 25.
The step portion 57 in the central portion of the slide lock 30 is attached to the portion 3
And the through hole 56 are visible, the slide knob 20 is located here.
The stepped portion 63 is applied and the projection 64 is fitted into the through hole 56 and engaged.

Although illustration and description have been omitted in the above description, a fusion plate 69 is provided on the opposite surface of the step portion 57 of the slide lock 30.
A concave hole 62 for fitting the concave hole 6 is formed.
The bottom surface of 2 and the end surface of the protrusion 64 coincide with each other.

The fusion plate 69 is fitted into the recessed hole 62 and the fusion plate 6 is inserted.
The fusion plate 69 and the protrusion 64 from the 9 side by an ultrasonic welding device.
And the bottom of the concave hole 62 are fused and integrally joined. This does not separate the three.

This state is the state shown in FIG. 9B. Referring to FIG. 5, when a finger is put on the slide knob 20 and pushed and slid in the direction of the triangular arrow 21, the tip of the slide knob 20 comes into contact with the end of the concave surface 26 of the housing 25, and further movement is prevented. To be done.

Along with this, the slide lock 30 which is engaged with the slide knob 20 is also moved so that the tip of the lock claw portion 19 is located slightly inward of the surface of the hole 48 of the partition wall 47. That is, the lock claw portion 19
Is in the retracted position, but in this state the slide lock 30
The step portion 55 is set so as not to come off the bent portion 46 of the guide 45.

In the assembled lock portion thus assembled, the lock claw portion 19 is moved to the retracted position by the movement of the slide knob 20, and when the finger is released, the lock claw portion 19 is moved into the power battery mounting portion 15 by the urging force of the spring 65. The advance position is reached, and the slide knob 20 is also in the original position.

The slide lock 30 is a guide 4 of the housing 25.
The movement direction is restricted only to the forward / backward direction by 5,46.
Moreover, the amount of advance / retreat is defined between the point where the end surface of the thick plate portion 51 abuts the partition wall 47 of the housing 25 and the point where the tip of the slide knob 20 abuts the end surface of the concave surface 26 of the housing 25. There is.

By supporting the stepped portion 55 with the bent portion 46 of the guide 45 that holds the stepped portion 55 away from this, a sufficiently safe and secure holding state can be obtained.

Since the slide lock 30 is held by the housing 25, the slide knob 20 only needs to have a function of moving the slide lock 30 in the retracting direction, and the slide knob 30 can also be moved in the retracting direction. Since it is pressed against the concave surface 26 of the housing 25 and slidably moved to be brought into contact with the end surface of the concave surface 26 to set the position, it does not cause any trouble.

As is apparent from FIG. 5B, the height (thickness) of this coupling lock portion is such that the dimension obtained by adding the slide knob 20, the housing 25 and the slide lock 30 is sufficiently thin. We were able to. It can be kept within the range of 3 mm to 4 mm, which is about half that of the conventional one.

In order to attach the power supply battery 6 in the state of FIG. 5 (b) with reference to FIG. 9, the lower end of the power supply battery 6 is engaged with the engagement protrusion 17 on the lower end of the terminal device body 9. Recess 1

The view (b) of FIG. 7 also corresponds to the view (b) of FIG. 5, except that the slide lock 30 and the slide knob 20 are connected to each other. Two pillar-shaped walls 75 extending from the slide knob 20 to the slide lock 30 and engaging projections 77 having engaging claws 76 opposite to each other are provided therebetween. The engagement protrusion 77 is formed to have elasticity and can be bent.

The slide lock 30 is provided with a recess 78 for receiving the columnar wall 75 and a through hole 79 through which the engaging projection 77 passes. By fitting the columnar wall 75 in the recess 78, the engagement projection 77 passes through the through hole 79, but is elastically deformed and passed by the engagement claw 76 so as to approach each other, and the engagement claw 76 of the slide lock 30 is inserted. When reaching the lower surface, the engaging claw 76 engages with the surface of the slide lock 30, and the engaging protrusion 77 elastically returns.

In this way, the slide knob 20 is engaged and locked with the slide lock 30. According to this embodiment, the positioning of the two is ensured by the fitting of the columnar wall 75 and the recess 78, and they are coupled and fixed by the engagement and locking by the engagement protrusion 77, so that the assembly is easy and the assembly is separated as necessary. The operation and effect are the same as those of the previous embodiment except that they can also be performed.
