Abstract

The utility model relates to a pressing type coaxial cable connecting socket, comprising an electrode chip 1, an upper cover 3, a lower cover 2 and a casing 4. The upper cover 3 and the lower cover 2 are provided with two corresponding slant faces, causing the upper cover 3 to slide to the lower cover 2 when the upper cover 3 is inserted. The opening of the lower cover is clamped, forming linear contact faces 51 and 52 with relatively great contact pressure between two blades of the electrode chip 1 and electrodes of a plug. The socket has large contract pressure and contact area with high operational reliability. Simultaneously, the scraping to the plug is avoided, lightening oxidation etching and electromagnetic interference caused by contact failure.

Description

The gang socket of push-press type coaxial cable

The utility model relates to the coaxial cable jockey, particularly relates to the socket of television system coaxial cable high reliability jockey.

In the prior art, a large amount of tap and the terminal access devices that use of information technology and data network are coaxial cable gang socket and plug.The plug center is a plug electrode, parameter standardization such as its diameter; And structure shown in Figure 1 is usually adopted in gang socket with matching, wherein forms to put between electrode slice 1 ' and the plug electrode 71 to contact 51 ', 52 '.Contact pressure only depends on the natural elasticity of electrode slice 1 ', and less, and about 50 grams of withdrawal force repeatedly patch and easily lose elastic force and cause loose contact; And under the situation that does not have plug electrode 71 to insert, electrode slice 1 ' is in closure state, as shown in Figure 2.When plug electrode 71 inserted, electrode slice 1 ' can produce scraping actions to plug electrode 71 compressing under the state of plug, damages its overlay coating, produces oxide etch, causes loose contact, produces electromagnetic interference, influence signal and transmits.Foreign data shows that in the maintenance capacity of TV data network, above-mentioned fault accounts for about 40%.

The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of gang socket that improves internal structure is provided, wherein the contact pressure of electrode slice and plug electrode can increase greatly with the insertion of plug, thereby the raising transmission reliability, and can avoid the scraping action of electrode slice to plug electrode.

The purpose of this utility model can be passed through to realize by the following technical solutions:

Manufacture and design the gang socket of a kind of push-press type coaxial cable, comprise electrode slice, lower cover and shell, also comprise loam cake.This loam cake exposes jut, and central authorities are porose, and in its opening part inboard, back the inclined-plane is arranged, and there is respective ramp in the opening part outside of described lower cover.They are loaded into after shell becomes gang socket, and loam cake can be to the direction slippage of lower cover when plug inserts described socket.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a contact condition schematic diagram for prior art socket electrode slice and plug electrode;

Fig. 2 is the initial closure state schematic diagram of socket electrode slice shown in Figure 1;

Fig. 3 is the schematic diagram that wire contacts for the utility model socket electrode slice with plug electrode;

Fig. 4 is the structure chart of the utility model socket;

The schematic diagram that Fig. 5 cooperates for the utility model socket and plug;

Fig. 6 is the decomposing schematic representation of the utility model socket internal structure.

Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:

The utility model provides the gang socket of a kind of push-press type coaxial cable, as shown in Figure 4, comprises electrode slice 1, and lower cover 2 and shell 4 also comprise loam cake 3.Loam cake 3 exposes jut 33, and central authorities are porose, and in its opening part inboard, back inclined-

plane

31,32 is arranged.There is

respective ramp

21,22 in the opening part of described lower cover 2 outside, and they are loaded into after shell 4 becomes gang socket, and loam cake 3 can be to the direction slippage of lower cover 2 when plug 7 inserts described socket.Described loam cake 3 and lower cover 2 are normally made with polymeric material by the little and whippy insulating material of coefficient of friction.

The both

wings

11,12 of the electrode slice 1 of the utility model socket are against the

medial surface

23,24 at lower cover 2 opening parts, and distance is slightly larger than the diameter of plug electrode 71 between the medial surface of the both

wings

11,12 of electrode slice 1, and its mated condition is referring to Fig. 5; After electroplating surfaces with tin is made, its elastic force meets the requirements described electrode slice 1 by the phosphorus bronze sheet pressing lap, and it is reasonable that cost is tending towards.

Fig. 6 is the decomposing schematic representation of the utility model socket internal structure.As seen from the figure, inclined-

plane

21,22, the lower cover 2 open ends outside and inboard inclined-plane 31, the 32 relative assemblings of loam cake 3 open ends.Above-mentioned

end chamfer

21,22 and 31,32, it between 25 °-35 °, in the present embodiment, is taken as 30 ° with respect to the tilt angle alpha of central axis.33 of the juts of loam cake 3 expose in copper shell 4 sockets outside.

Fig. 5 shows the situation after the utility model socket and plug is pegged graft.During grafting, plug electrode 71 loose fits enter between the both

wings

11,12 of electrode slice 1, plug 7 promotes the jut 33 of loam cake 3 subsequently, make the direction slippage of loam cake 3 to lower cover 2, the interior inclined-

plane

31,32 of loam cake 3 presses to the outer inclined-

plane

21,22 of lower cover 2 immediately, two pairs of inclined-plane actings in conjunction are decomposed transmission with above-mentioned grafting thrust, become the chucking power of lower cover 2 opening parts two

medial surfaces

23,24 in shell 4.Because the both

wings

11,12 of this two

medial surface

23,24 and electrode slice 1 are parallel substantially, described chucking power promptly can and be between the plug electrode 71 of Cylinder at the both

wings

11,12 of electrode slice 1, form the contact-making surface that is

wire

51,52 that has big contact pressure as shown in Figure 3, finish plug 7 and be connected with the reliable of this gang socket.

Among the utility model embodiment, when the plug electrode diameter was the 0.5-1.0 millimeter, it was 1000-2000 gram that formed contact pressure makes the required withdrawal force that pulls the plug out of the socket, much larger than the corresponding withdrawal force of the jockey 50-100 gram of prior art.

Compare with prior art, the advantage of the utility model socket is, can increase coaxial cable and connect dress The contact of putting and contact area improve jockey and institute's access network reliability of operation, simultaneously Avoid the scraping to plug electrode, thereby avoided oxide etch, reduced the electricity that loose contact produces Magnetic disturbance.
