Description

Connector for Wireless Communication Equipment

The present invention relates to a connector for a wireless communication device, and more particularly to a connector for a wireless communication device to improve the fastening property in the vertical and horizontal direction, and to return to the design position in the non-fastening state.

In general, the connector is composed of a plug and a jack to transmit high-frequency transmission of various communication equipments to transmit and receive specific signals such as high frequency RF signals to facilities and components such as switchboard equipment, base station equipment, and repeaters for wired or wireless communication. It is used as a connection medium between cables or PCBs.

The connector is classified into a coupling nut method and a snap-on type according to the fastening method. The coupling nut method has a male screw on the outer circumferential surface to be fastened to a plug and a nut having a nut mounted on the outer circumferential surface. The formed jacks are screwed together and connected to each other. On the other hand, in the snap-on method, a protrusion is formed on one end of the body of the plug, and a groove in which the protrusion is fitted is formed inside the body of the jack, and thus is coupled to each other in a fitting manner.

Regardless of the difference between these methods, in the connection of PCB and PCB, the connection of enclosure and PCB, plugs and jacks are installed on each of the connecting objects on the plate, and they must be connected to each other. At this time, it is difficult to visually check whether the plug and the jack match the correct position. In particular, in the case of combining a plurality of plugs and a plurality of jacks, it is very difficult to confirm the exact position, which takes a lot of time required for coupling. .

In view of such a problem, Applicant Patent No. 10-1049171 of the present invention describes in detail a connector that allows the plug or jack to be interconnected smoothly by having a predetermined fluidity in the vertical and horizontal directions. Doing.

Figure 2 is a cross-sectional configuration of the connector for a wireless communication device according to a preferred embodiment of the present invention, Figure 3 is a cross-sectional configuration of the body when the body is retracted when the guide ring is separated when combining the counterpart in FIG.

2 and 3, respectively, the connector for a wireless communication device according to a preferred embodiment of the present invention, the binding hole 120 is provided with a mating article 1 is coupled to one end, the center conductor 610 inside ) Has a body 100 coupled in an insulated state by the insulator 600, and a hole 720 into which the body 100 is inserted, and a fastening hole 710 is provided on the fastening object 2. The fixed plate 700 is fixed and coupled to the outer circumference of the body 100 inserted into the hole 720 of the fixing plate 700, the state of the body 100 in the state before the counterpart 1 is fastened A guide ring 400 which prevents displacement and is detached to the rear of the fixing plate 700 and the hole 720 when the counterpart 1 is fastened so that the body 100 can be tilted, and the body ( Fixed ring 300, the fixing plate 700 and the body to be coupled to the rear end body 100 of the guide ring 400 coupled to the 100 to prevent the separation of the guide ring 400 Both ends are in contact with the lower end of the binding hole 120 of the sieve 100, the spring 500 to enable tilting and pressing of the body 100, the binding hole 120 of the body 100 and Covering the outer portion of the upper portion of the spring 500, it comprises a housing 200 for providing an inclined surface when the mating of the counterpart (1) to facilitate the coupling.

Hereinafter, the configuration and operation of the connector for a wireless communication device according to a preferred embodiment of the present invention configured as described above in more detail.

First, the shape of the body 100 is a cylindrical structure, but the diameter of the binding sphere 120 that is coupled with the counterpart (1) is the largest, the diameter of the central portion 130, the spring 500 is wrapped In comparison, the diameter of the small diameter portion 110 that is the opposite end of the binding hole 120 is provided to be the smallest.

The upper side of the spring 500 has a protruding end 140 due to the difference in diameter between the central portion 130 and the coupling hole 120, and the spring 500 is accommodated so that the upper portion of the spring 500 can be accommodated. The protruding end 140 is in contact with the receiving groove 150 upward.

The height of the receiving groove 150 is reduced by the formation of the receiving groove 150 is advantageous in miniaturization. This is different from simply reducing the thickness of the protruding end 140. When reducing the thickness of the protruding end 140, the coupling force with the housing 200, which is forcibly fitted to the outer surface of the protruding end 140, is weakened. This may cause problems such as the housing 200 is separated.

Inside the central portion 130 of the body 100, the insulating portion 600 is coupled, the central conductor 610 is insulated from the body 100 by the insulating portion 600 of the binding sphere 120 It is provided to protrude inward.

Body 100 of the above configuration is fitted to the housing 200 described above. The shape of the housing 200 is a lower portion of the open, the upper portion is a cylindrical structure of the center portion is open, the interference fit in the upper side of the binding hole 120.

The housing 200 located on the upper side of the binding hole 120 provides an inclined surface 210 which is lowered toward the center side, so that the counterpart 1 may not be accurately aligned when the counterpart 1 is engaged. It can be coupled to guide to the binding sphere 120 side.

Then, in the state in which the spring 500 is fitted to the outside of the central portion 130 of the body 100, the small diameter portion 110 is inserted into the hole 720 of the fixing plate 700 so as to be located on the opposite side.

As shown in FIGS. 2 and 3, the hole 720 of the fixing plate 700 has a smaller shape than the diameter of the lower part. For the specific action of the hole 720 shape, This will be described in more detail below.

The body 100 is inserted from the upper side of the fixing plate 700 having a smaller diameter of the hole 720 to the lower side having a larger diameter.

The guide ring 400 is coupled to the end of the central portion 130 of the body 100 protruding downward from the fixing plate 700. The shape of the guide ring 400 is narrow in cross-section and the lower portion is wide, which corresponds to the shape of the hole 720.

The guide ring 400 may be provided integrally with the body 100.

After coupling the guide ring 400 as described above, the fixing ring 300 is coupled between the small diameter portion 110 and the central portion 130 of the body 100 to fix the guide ring 400 so as not to leave.

* A fixing groove to which the fixing ring 300 may be coupled may be provided at the boundary between the small diameter portion 110 and the central portion 130.

Therefore, the body 100 can be prevented from being displaced from side to side.

That is, in the state where the center of the planar circular body 100 and the center of the hole 720 are positioned to coincide with each other, it is prevented from being displaced by the guide ring 400. This is to ensure that the body 100 is always in the design position in the state before coupling with the counterpart 1, and is displaced to the body 100 by an external physical force before coupling with the counterpart 1. It is possible to prevent the occurrence of an error when combined with the counterpart (1).

The prevention of such an error can make the coupling with the counterpart easier, and the effect can be greater especially when combining a plurality of connectors and the counterpart at the same time.

3, when the spring 500 is compressed by the coupling pressure generated when the counterpart 1 is in contact with the counterpart 1, the guide ring 400 moves from the hole 720. Departure.

At this time, the hole 720 is smaller than the diameter of the upper diameter, the side is inclined, the guide ring 400 has a shape corresponding to the hole 720, the guide ring 400 is fixed plate Departure is prevented to the upper side of the 700, and can be separated only to the lower side by the action of the coupling pressure.

When the guide ring 400 is separated to the lower side of the hole 720 as described above, a space is formed between the guide ring 400 and the hole 720, the body 100 is left and right by the space. It can be tilted.

That is, the guide ring 400 prevents the occurrence of displacement of the body 100 by preventing space from occurring in the side portions of the body 100 and the hole 720 before the counterpart 1 is fastened. 1) When it is fastened to the space between the body 100 and the hole 720 is generated by separation, it is possible to press and restore the tilting and vertical displacement of the tilt in a specific direction.

4 to 11 are cross-sectional views showing another embodiment of the guide ring 400, respectively.

In Figure 4, the outer surface 410 of the guide ring 400 is inclined but convex, in Figure 5 the outer surface 410 is shown inclined but concave, Figure 6 is the same width from the middle to the top, An example of the outer side surface 410, the width of which goes from bottom to bottom toward the bottom, is given.

7 illustrates that the outer surface 410 of the guide ring 400 is stepped. 8 and 9 are concave or convex while the side of the fixing part 700 is inclined, the outer surface 410 of the guide ring 400 is a stepped structure, Figures 10 and 11 are opposite to the fixing part ( The hole 720 of the 700 has a stepped structure in the inclined state, and the outer surface 410 of the guide ring 400 shows a convex or concave state in the inclined state.

As shown in FIGS. 2 to 11, the guide ring 400 may have a ring structure having a lower width than an upper end thereof, and may be applied to the present invention regardless of its structure. Of course, according to the shape of the guide ring 400, the shape of the hole 720 may be deformed to be equally engraved, but it may be easily understood that the guide ring 400 may be applied irrespective of the guide ring 400.

That is, the side of the hole 720 is an inclined surface, the outer surface of the guide ring 400 may perform the operation of the guide ring 400 described above, even if formed in a step shape as shown in FIG.

As described above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above-described embodiments, and various modifications are made within the scope of the claims and the detailed description of the invention and the accompanying drawings. It is possible to carry out by this and this also belongs to the present invention.
