Description

A kind of wire signal socket

Technical field

The utility model relates to signal plug, particularly a kind of wire signal socket.

Background technology

According to standard GB/T 8898-2011, between cable network antenna coaxial socket and protective earthing circuit, should there is the requirement of quarantine measures, antenna isolator has become Set Top Box and TV to be realized the indispensability of this requirement and selects.In actual use procedure, conventionally antenna isolator is independently placed between the rf inputs of cable TV signal socket and Set Top Box, TV.Especially while being used on TV, because TV adopts wall hanging mounting means conventionally, the rf inputs of TV is often blocked by screen, inconvenience when isolator is installed; As be installed on cable TV socket end and affect again attractive in appearance and take up room.

Utility model content

The technical problems to be solved in the utility model is: provide one to have isolation features wire signal socket, solved in conventional socket without isolation features, inconvenient problem with use.

For addressing the above problem, the technical solution adopted in the utility model is: a kind of wire signal socket, comprise socket panel, and also comprise antenna isolator, the socket that the output of antenna isolator is arranged on socket panel connects in hole, and antenna insulator body and input part are placed in socket panel rear.

Further, described antenna isolator comprises ground wire capacitance and signal capacitance, ground wire capacitance is connected between the input ground wire and output ground wire of antenna isolator, and signal capacitance is connected between the input end signal line and output end signal line of antenna isolator.

The beneficial effects of the utility model are: this wired socket carries antenna isolation features, and without using in addition antenna isolator, user is easy to use again, attractive in appearance succinct.

Brief description of the drawings

Fig. 1 is the utility model embodiment profile;

Fig. 2 is the utility model embodiment front elevation;

Fig. 3 is the internal insulation circuit diagram of the utility model antenna isolator;

In figure, number: 1 is antenna isolator, and 2 is socket panel, and 11 is the output of antenna isolator, 12 is the input of antenna isolator, and 13 is the shielding case of antenna isolator, and 21 connect hole for socket, C1 is signal capacitance, and C2, C3 are ground wire capacitance, and GND is ground wire.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the utility model embodiment profile, and antenna isolator and traditional cable TV socket are organically combined, and forms an entirety; Antenna isolator 1 body and input part are placed in socket panel 2 rears, and antenna isolator output 11 connects hole 21 by the reserved socket of panel and stretches out; Antenna isolator input 12 connects the holding wire that enters into user house.

Fig. 2 the utility model embodiment front elevation, antenna isolator output 11 forms are identical with the interface on conventional socket panel, identical, beautiful and applicable with traditional cable TV socket method when user uses.

Fig. 3 is the internal insulation circuit diagram of the utility model antenna isolator 1, and signal isolation is connected between input end signal line and output end signal line and is realized by signal capacitance C2, adopts in the present embodiment high-voltage capacitance, capacitance 1000pF, 2000V.Ground wire isolation: ground wire isolation capacitance C1, C3 parallel connection, and ground wire isolation capacitance is connected between input ground wire and output ground wire, and ground wire GND connects the shielding case 13 of antenna isolator, is also specifically to adopt high-voltage capacitance, capacitance 1000pF, 2000V.

The internal insulation circuit diagram of antenna isolator can finely be realized buffer action, outside without separately connecing antenna isolator, therefore the utlity model has safe, convenient, attractive in appearance feature.
