As shown in FIGS. 1 and 3, a slide spring device 100 is interposed between the fixing member 10 and the moving member 20, and the slide spring device 100 connects the moving member 20 to the elastic force of the spring. By a semi-automatic sliding movement.

The slide spring device 100 includes a spring casing 50 composed of one body.

The spring casing 50 has a plate shape made of hard plastic or metal, and a plurality of spring accommodating chambers 51A and 51B, which accommodate the compression springs 80, are formed in parallel. In this embodiment, the spring accommodating chambers 51A and 51B are arranged in two, respectively, as shown in Figs.

The spring receiving chamber (51A, 51B) has a width (W) for receiving the outer diameter (D) of the compression spring (80) to compress the compression spring (80) to be inserted into the spring storage chamber (51A, 51B) Spring latching jaw 53a which is formed at a position where the spring inlet 52 and the spring accommodating chambers 51A and 51B are shifted up and down to prevent the compression spring 80 stored in the spring accommodating chambers 51A and 51B from being separated. 53b) is formed.

Here, as shown in FIG. 7, the width W of the spring inlet 52 is formed at least larger than the outer diameter D of the compression spring 80, and the length L of the spring inlet 52 defines the compression spring 80. It is formed at least longer than the length at the maximum compression.

In the present invention, the spring inlet 52 is not only a necessary component for assembling the compression spring 80 but also becomes an element capable of constituting the spring casing 50 as one component.

In addition, the upper and lower surfaces of the spring casing 50 can be chamfered close to the diameter of the compression spring 80 accommodated in the spring storage chambers 51A and 51B as shown in FIG. The thickness t of 50) can be made thin.

In this embodiment, the spring inlet 52 is formed at either end of the spring storage chambers 51A and 51B, but may be provided at the center.

A pair of fixed-side actuating pins 60 and a pair of moving-side actuating pins 70 are provided to move forward and backward with a constant uniaxial spacing L in the opposite directions of the spring casing 50.

The fixed side actuating pin 60 is inserted into the spring housing chamber 51A of one side of the spring casing 50 so as to be able to move forward and backward, and the movable side actuating pin 70 of the other side of the spring housing chamber 50 of the spring casing 50 ( 51B) is inserted into the retractable motion.

The fixed side actuating pin 60 and the movable side actuating pin 70 are inserted into the small diameter portion 60a and the spring casing 50 wrapped in the compression spring 80 as shown in FIG. It consists of a large diameter part 60b which receives a repulsion force. A spring engaging jaw 60c is formed between the small diameter portion 60a and the large diameter portion 60b.

Compression springs 80 are respectively installed in the spring storage chambers 51A and 51B of the spring casing 50. The plurality of compression springs 80 functions to push the fixed side actuating pin 60 and the movable side actuating pin 70 in opposite directions with elastic repulsive force.

In the present embodiment, the two fixed side actuating pins 60 are made of plastic and connected to the fixed side fastener 62 having the fixed side hinge shaft 62a, and the two movable side actuating pins 70 are made of plastic. And a moving side fixture 72 having a moving side hinge shaft 72a.

At this time, the direction of both fasteners 62 and 72 are assembled to face in the opposite direction as shown in FIG.

On the other hand, both ends of the fixing member 10 includes a guide rail portion 11 configured in the 'c' shape to guide the sliding operation by sandwiching both ends of the movable member 20.

The guide rail portion 11 is formed to extend from one body to the body of the fixing member 10, unlike the conventional rail shaft is removed, the body meat is not reduced, the cross-sectional coefficient is increased to increase the durability against bending stress.

At this time, both ends of the moving member 20 is coupled to the lubrication member 21 made of plastic to smooth the sliding operation with the guide rail portion (11).

The slide spring device according to the present invention configured as described above is assembled as follows.

First, the compression spring 80 is compressed by the length L of the spring inlet 52 and inserted into the spring inlet 52 of the spring casing 50. In this case, the compression spring 80 is elongated in the longitudinal direction by the elastic repulsive force and is respectively positioned in the corresponding spring storage chambers 51A and 51B.

At this time, the compression spring 80 is engaged with the upper and lower spring engaging jaw (53a, 53b) formed in the spring storage chamber (51A, 51B) is prevented from being separated from the spring storage chamber (51A, 51B).

In this state, when the fixed side actuating pin 60 and the movable side actuating pin 70 are inserted into the spring storage chambers 51A and 51B of the spring casing 50, as shown in FIG. 60c) comes into contact with one side of the compression spring (80).

Thereafter, the hinge shaft 62a of the fixing side fixture 62 is fitted into the hinge hole 10a of the fixing member 10, and the hinge shaft 72a of the moving side fixture 72 is hinged of the moving member 20. It fits in the ball 20a.

In this case, as shown in FIG. 2, when the moving member 20 is positioned to one side, the compression spring 80 maintains a state in which it is extended to the maximum.

For example, when the movable member 20 is located below and is forced to move upward, the position of the fixture 62 of the fixed side actuating pin 60 does not change, and the fastener 72 of the movable side actuating pin 70 does not change. The position of is increased and the compression spring 80 is compressed. The greatest amount of compression is when both fixtures 62 and 72 are on the same horizontal line X.

After that, when the position of the same horizontal line X is exceeded, the movable member 20 automatically moves upward by the compression repulsion force accumulated in the compression spring 80.

When the moving member 20 located above moves downward, it is made in the reverse order.

At this time, the moving member 20 moves along the guide rail portion 11 formed in the 'c' shape formed on both ends of the fixing member (10).

The slide module configured and operated as described above may install the compression spring 80 on the spring casing 50 without the need for a cover means. Therefore, the number of parts and manufacturing labor can be reduced by eliminating the cover means, and the spring casing 50 can be made thin.

At this time, the thickness (t) of the spring casing 50 may be configured to be close to the outer diameter (D) of the compression spring.

In addition, the fixing member 10 by the guide rail portion 11 formed in the 'c' shape to guide the movement of the moving member 20 on both ends of the fixing member 10 according to the increase in the cross-sectional coefficient Flexural stress is enhanced, improving installation durability.

In addition, the bending deformation of the guide rail portion 11 is less, leading to a stable sliding operation of the moving member (20).

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea and the following of the present invention are provided by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

As described above, according to the slide spring device for a communication terminal and the slide module including the same according to the present invention, the spring casing is manufactured as a single piece, thereby reducing the number of assembly parts and manufacturing labor, and making the spring casing thin as the diameter of the spring. There is an effect that can implement a portable communication terminal in a slim form.

In addition, since the compression spring wraps around the small diameter part of the operation pin, the compression spring and the extension of the compression spring are guided by the small diameter part to prevent the compression springs stored in the same spring storage chamber from being twisted together or broken by friction. It has an effect.
