Description

The signal connector structure

The utility model relates to a kind of signal connector structure, is to connect with the signal connector of coaxial cable as signal transmission carrier about being used for, and is meant a kind of signal connector structure of being convenient to make production especially.

Present cable television system or wideband network system utilize coaxial cable to be used as the carrier of transmission signal, wherein when constituting cable TV system or wideband network system, the series connection of coaxial cable, the circuit demand of one-to-many, all to utilize various signal connector to finish transmission or shunt, for example the double end connector or the signal distributor of signal; As Fig. 1, shown in Figure 2, shown in the figure is a kind of of signal connector, it is by shell 41 in regular turn, waterproof jacket 42 and signal terminal 43 are formed, shell 41 is that metal material is made the cylinder that a hollow runs through, one end is a link 411, has an opening 4111 on it, one end then is combination end 412, also has an opening 4121 on it, and be formed with screw thread in the outer rim of shell 41, for the engagement that is spirally connected of the joint of coaxial cable, waterproof jacket 42 is to make the rough internal diameter that equals shell 41 of its external diameter of cylinder that a hollow runs through by flexible materials such as rubber, just can fill in shell 41, and opening 4111 places of waterproof jacket 42 corresponding links 411 are provided with a protuberance 421 that just equals opening 4111, protuberance 421 stretches out in the link 411 of shell 41, and make opening 4111 sealings fully, and aqueous vapor can't be infiltrated in shell 41 by the seam crossing of opening 4111, reach good waterproof effect, certainly have an opening 4211 on the top of protuberance 421, electrically connect for the coaxial cable insertion; Signal terminal 43 is that metal material is made, one end is an input 431, use for the coaxial cable signal and connect, the other end is a link 432, in order to electrically connect with circuit board, wherein signal terminal 43 centre are coated with one with the insulating case 433 made of insulation material, the rough internal diameter that equals waterproof jacket 42 of the external diameter of insulating case 433, signal terminal 43 inserts in the waterproof jacket 42 with input 431, be packed in waterproof jacket 42 by insulating case 433 again and be fixed in the shell 41, wherein the input 431 of signal terminal 43 just is aligned with the opening 4211 of protuberance 421, insert and its electric connection for coaxial cable, 432 of links can utilize lead or directly be connected on the circuit board and electrically connect with it.

Process at actual production one signal connector is:

1. a sheet metal punching out is become signal terminal;

2. signal terminal is installed on the insulating case;

3. on insulating case, install waterproof jacket;

With the punching press in the lump of signal terminal, insulating case, waterproof jacket in shell.

Yet be not difficult to find by the process of above-mentioned structure and production, waterproof jacket is that the purpose that reaches waterproof is to make for the flexible material of tool, has the rough internal diameter that equals shell of size, and signal terminal cooperates the size in coaxial cable axle center, its size is less than the internal diameter of waterproof jacket, therefore have one between the output of waterproof jacket and signal terminal at interval, with terminal, insulating case, waterproof jacket punching press in the lump is in shell the time, because the internal diameter of shell is rough identical with the external diameter of waterproof jacket, and insulating case is to utilize friction tight relation that signal terminal is fixed in the shell, therefore when punching press, must impose certain strength, and corresponding relation must be suitable accurately, but because waterproof jacket has flexible, therefore corresponding relation has error slightly, to make the waterproof jacket bending, and can't be correct enter in the shell, even because the bending of waterproof jacket, and the input that is pressed into signal terminal makes its bending, to make input can't be aligned with the opening of protuberance, promptly can't electrically connect, cause the generation of defective item for the axle center insertion of coaxial cable.

The purpose of this utility model is to propose a kind of signal connector structure of being made up of shell, waterproof jacket, supporter and signal terminal.Deflection or damage when it can prevent the signal terminal punching press, thus the existing in prior technology problem solved.

The technical scheme that the utility model adopted is that it includes:

One shell, it is the cylinder that a hollow runs through, it combines with coaxial cable;

One waterproof jacket, it is the cylinder that a hollow runs through, tool is flexible, just can place in this shell;

One supporter, it is the cylinder that runs through of hollow of an insulation, just can place in this waterproof jacket, and fill up in this waterproof jacket, and in an end that should coaxial cable inserts is formed with the guide groove that this coaxial cable of guiding inserts;

One signal terminal, it is a metallic conductor, places in this supporter, in order to electrically connect with this coaxial cable.

Characteristics of the present utility model are:

According to the signal connector structure that the utility model disclosed, wherein utilize supporter to envelope signal terminal fully, again punching out in the lump in shell, a little error in the time of so can avoiding punching press and make signal terminal bending, effectively prevent signal deflection or damage, reduce the generation of defective item.

Fig. 1 and Fig. 2 are known signal connector organigram;

Fig. 3 is a structure decomposing schematic representation of the present utility model;

Fig. 4 is a tectonic association generalized section of the present utility model.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.According to the signal connector structure that the utility model disclosed, be in order to the transmitting signals that continues, such as being applied in the line communication systems such as cable television system or wideband network system, the carrier that utilizes coaxial cable to transmit as signal, and signal connector is as the series connection or the one-to-many connection along separate routes of coaxial cable.

As shown in Figure 3 and Figure 4, according to the signal connector structure that the utility model disclosed, it mainly includes: shell 11, waterproof jacket 12, supporter 13 and signal terminal 14; Shell 11 is to be made for the cylinder that a hollow runs through with metal material, one end is a link 111, the other end then is combination end 112, and form the less opening of an internal diameter 1111 respectively at two ends, reach big opening 1121, and be formed with screw thread 113 in the outer rim of shell 11, for the engagement that is spirally connected of the joint (not shown) of coaxial cable.
