The present invention relates to a pogo-pin for driving slides of a slide-type mobile phone, and more particularly, to a low-cost manufacturing and defective rate by improving a pogo-pin structure for a slide-type mobile phone that slides a bisected body of a mobile phone. It is to provide a pogo pin for the slide drive of the slide-type mobile phone that can be used with compatibility with various models of the slide-type mobile phone by greatly reducing the size, increase the expansion width, and easy installation.

In general, a mobile phone has various body opening and closing methods such as a folding type and a pivot type to open and close a divided body. However, a mobile phone that is a sliding type that is opened and closed while the divided body slides up and down or left and right in recent years is widely used.

As shown in FIG. 1, the slide-type mobile phone 101 forms slide rails 104 and 105 on the corresponding slide surfaces so as to slide the divided bodies 102 and 103, and the body along the slide rails 104 and 105. The torsion springs 106 and 107 are elastically connected to the bisected bodies 102 and 103 so as to maintain the slide state at each end when the slides 102 and 103 are operated. When the external force for sliding the upper and lower sides 102 and 103 is applied, the sliding state is maintained at the desired position up and down.

However, in the case of a slide-type mobile phone using such a torsion spring, the torsion spring is manufactured to have a lifespan that can operate the slide operation about 60,000 to 70,000 times. When the torsion spring is cut inside the body of the mobile phone, the torsion spring must be replaced after disassembling the entire mobile phone. Therefore, the repair process is very cumbersome, and the life of the torsion spring is short. It was desperately desired.

In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2004-0105657 discloses a push rod unit for a torsion spring as a slide driving device of a slide type mobile phone.

In addition, the domestic utility model registration publication No. 20-0362198 discloses the prior art with respect to the pogo pin,

In the case of the prior art, the cylinder is mainly produced by cutting both ends of the pipe to a predetermined length, so that secondary processing is required due to burrs generated on the cutting surface, and thus there are many working processes, and secondary processing of the cutting surface is difficult. There was a problem that the defect rate was also very high, and since insert injection molding is performed using synthetic resin for connecting pins for fixing cylinders, a large amount of defective products that do not match flatness is generated, and synthetic resin shrinks when forming connecting pin inserts. While pressing the cylinder, the piston in the cylinder often causes a malfunction in actual use, and there was a problem that a metallic noise occurs due to the malfunction. In addition, the use of two or more pogo pins made it difficult to avoid manufacturing cost problems.

In addition, since two or more cylinders are precisely inserted into the mold and the connecting pins are injected, workability is very low, and manufacturing costs are inevitably raised.

Accordingly, the present invention is to provide a pogo pin for the slide drive of the slide-type mobile phone of a novel configuration that can eliminate the problems of the slide drive or pogo pin of the conventional slide-type mobile phone as described above,

In particular, the present invention constitutes a slide-driven pogo pin for a slide-type mobile phone, and manufactures an outer housing and an inner housing, which are configured in a cylindrical form, by a deep drawing process, and then springs inside the respective housings. One or more elastic installations to greatly expand and contract the stroke, minimize the noise generated by joints during low-cost manufacturing and operation, and secure the reliability by the spring guider, and minimize the assembly cost and process defects by minimizing parts The present invention has been completed with the technical problem of the present invention by providing a pogo pin for driving a slide of a slide-type mobile phone.

It provides a number of action effects, such as being compatible with the various types of slide-type mobile phone (8), its operation and the like will be described in more detail below.

The pogo pin 1 of the first embodiment of the present invention is used as a slide driving device of the slide type mobile phone 8, and the upper and lower sides of the slide type mobile phone 8 are formed by the elasticity of the first and second springs 5 and 6. In the slide operation, the elasticity of the first and second springs 5 and 6 is applied at a desired position (top dead center or bottom dead center), thereby arbitrarily holding the body of the mobile phone 8 so as not to slide.

That is, when the user slides the body of the mobile phone 8 up and down with a slight force, one of the bodies at the top dead center or the bottom dead center moves the slide in the bottom dead center or the top dead center. The pogo pin (1), which was elastically supported by the inner housing (3) and the spring guider (4) respectively compressed the first and second springs (5, 6) in response to the slide operation of the body, and then moved out of the upper and lower center portions again. As the surface-compressed first and second springs 5 and 6 expand, the inner housing 3 and the spring guider 4 slide and extend on the outer housing 2 and the inner housing 3, respectively, in one of the up and down directions. By reaching the end of the first and second springs (5,6) by the elasticity of both the body is to maintain a stationary state in that position.

Particularly, in the present invention, the inner housing 3 and the spring guider 4 slide in two stages on the outer housing 2 so that the stroke is very large, and the outer housing 2 and the inner housing 3 Since it is manufactured by deep drawing process, the slide surface end of the product is clean and there is almost no defect rate, and the fitting parts 4a and 4b of the spring guider 4 are assembled to the first and second springs 5 and 6. Since the expansion and contraction operation is performed in the state, the reliability of the operation is doubled due to the stable structure. When inserting the connecting pins 7 at both ends of the pogo pin 1, the external housing 2 and the inner housing 3 are compressed and operated. Problems that cause defects can also be eliminated.

In addition, the pogo pin 1 provided in the second embodiment of the present invention as shown in FIGS. 5 to 7 also has a single first spring 5 when the inner housing 3 slides onto the outer housing 2. ) Will only control the up and down slide operation of the mobile phone 8 while the compression and stretching operation is performed,

It is possible to manufacture the pogo pin 1 at a lower cost by controlling a large stroke by a single first spring 5 alone, and can significantly increase the reliability of the operation.

In addition, when the existing pogo pin is used in the slide-type mobile phone (8), two pogo pins are required, but the present invention has a large operating stroke, so that a single mobile phone (8) of various sizes can be used as a single pogo pin (1). It can also be used to provide a sliding mobile phone (8) at a low cost.

As described in detail above, the slide-driven pogo pin 1 of the slide-type mobile phone provided by the present invention includes an outer housing 2, an inner housing 3, and a spring guider 4, respectively. By elastically installing only the spring (5, 6) or a single first spring (5) to be configured to slide compression and extension, the slide stroke is very large, thereby driving the slide-type mobile phone 8 of the upper and lower slides of various specifications It can be used as a pogo pin (1) for excellent compatibility,
