Abstract

The utility model discloses a communication product connector. A BMA connector is mounted on a cover board of a communication product, an inner conductor of one end of a coaxial cable is inserted into the BMA connector, a shield guide post is a hollow copper post with one open end, the shield guide post is mounted on the back face of the cover board, the lateral face or bottom face of the shield guide post is provided with a pore with a size only for the inner conductor of the coaxial cable to penetrate through, the inner conductor of the coaxial cable penetrates into the shield guide post and extends out from the pore, the extended inner conductor of the coaxial cable is directly welded with one end of a coupled wire, and the other end of the coupled wire is fixed on the inner surface of the cover board. The connector is applicable to various communication products requiring the BMA connector, such as a filter, a duplexer, a combiner and the like. Indexes of the communication products using the connector cannot be affected by contraction of the connector. The connector is simple and convenient in installation and high in firmness, and realizes application of blind mating type connectors on cavity filters, duplexers and combiners.

Description

A kind of communication products connector

Technical field

The utility model belongs to the network optimization product in electronic information and the mobile communication technology field, specifically is a kind of communication products connector.

Background technology

BMA (the blind A of the joining type of Blind Mate A) connector is a kind of blind New-type radio-frequency connector of joining that grew up in recent years in the world, it is the push-in type distortion of SMA series of products, interface adopts air interface, has advantages such as volume is little, reliable, the mechanical superior electrical property of contact, butt joint convenience.But because the BMA connector has Telescopic, use on cavity body filter, duplexer and mixer, very big to the index influence.

Cavity body filter, duplexer and mixer inside all are made up of the resonant cavity that links to each other successively, a resonant rod has been installed in the center of each resonant cavity, and first is fixed on the connector of input port and output port with scolding tin by coupled-wires with last resonant rod.

Coaxial cable is one of modal transmission medium in the local area network (LAN).It is used for the pair of conductors of the information of transmitting is that outer conductor according to one deck drum type brake is enclosed within inner wire (a thin core) outside, the structure system choosing of isolating mutually with insulating material between two conductors, the center of circle of outer contact and central shaft heart yearn is on same axle center, so be called coaxial cable, why coaxial cable is designed to like this, also is in order to prevent the transmission of external electromagnetic wave interference abnormal signal.

The connected mode of BMA connector between coaxial cable and cavity body filter, duplexer or mixer is (as Fig. 1): BMA connector 3 is installed in cover plate 2 tops, the inner wire of coaxial cable 5 one ends directly inserts in the BMA connector 3 and connects, and an end directly is weldingly connected with interior first resonant rod 4 of cavity.During test component, flexible connector causes the displacement of coaxial cable 5, thereby causes electromagnetic field variation in the cavity 1, changes the index of device.

The utility model content

Technical problem to be solved in the utility model provides a kind of new communication products connector, it is applicable to the various BMA connectors that need to use such as on the communication products such as filter, duplexer and mixer, makes its index not be subjected to the influence of connector extending and contracting after using this connector.

Communication products connector described in the utility model, it comprises the BMA connector that is installed on communication products cover plate or the chamber wall, the inner wire of coaxial cable one end inserts in the BMA connector, the dielectric of coaxial cable is stuck in the output of BMA connector, and the shielding outer conductor of being stripped from is welded on the shell of BMA connector; It also is provided with shielding guide pillar and coupled-wires, described shielding guide pillar is the hollow copper post of single-ended opening, the output of shielding guide pillar openend and BMA connector is corresponding and be installed in the cover plate or the wall back side, chamber, the side of shielding guide pillar or bottom surface are equipped with one and only can pass the aperture of inner conductor, inner conductor stretches in the shielding guide pillar and from aperture stretches out, inner conductor of stretching out and coupled-wires one end directly weld, and the other end of coupled-wires is fixed on cover plate or chamber wall inner surface.

The both sides, top of described shielding guide pillar are provided with installing hole, directly link to each other by screw with the BMA connector.

The utility model is installed simple and convenient, and fastness is strong.Make the blind formula connector of joining be used on cavity body filter, duplexer and the mixer and become a reality.The utility model is applicable to that the various use BMA connectors that need are such as on the communication products such as filter, duplexer and mixer.Make its index after using this connector, be not subjected to the influence of connector extending and contracting.

Description of drawings

Fig. 1 is original connected mode structural representation;

Fig. 2 is that the utility model is installed structural representation on the cover board;

Fig. 3 is that the utility model is installed in the structural representation on the wall of chamber.

Embodiment

As shown in Figures 2 and 3, a kind of communication products connector described in the utility model comprises BMA connector 3, coaxial cable 5, shielding guide pillar 6, wherein:

Shielding guide pillar 6 is close to BMA connector 3 outputs, BMA connector 3 usefulness coaxial cables 5 inner wires directly insert connection, coaxial cable 5 other ends pass in the aperture of shielding guide pillar 6, and the shielding outer conductor of coaxial cable is fixed on the aperture with scolding tin, and stretches out inner conductor.

It is that the dielectric external diameter is not more than softness or the semihard cable that 1.54mm and inner wire diameter are not more than 0.54mm that coaxial cable 5 requires.And when coaxial cable 5 one end inner wires directly inserted BMA connector 3, coaxial cable 5 dielectrics just in time blocked the output of BMA connector 3, and the shielding outer conductor of being stripped from is welded on the discharge case of BMA connector 3.

Shielding guide pillar 6 is copper posts of boring, and radius is the radius of BMA connector, and height is less than housing depth, and thickness is 0.5mm.Have only open top, and be added with installing hole, be used for being close to BMA connector output, reach the effect of trapped electromagnetic wave in the both sides, top.An aperture is made a call in side or bottom surface, only can pass coaxial cable.

The utility model can be fixed on the cover plate 2 (Fig. 2) of communication products or the chamber wall (Fig. 3) in actual use, so must be installed separately on the two sides of cover plate 2 or chamber wall between BMA connector 3 and the shielding guide pillar 6, put fixing in order with the screw 8 of M2.5 simultaneously.Coaxial cable 8 inner wires and the coupled-wires 7 of stretching out from shielding guide pillar aperture directly are weldingly connected, the other end of coupled-wires 7 is welded direct on the mounting screw of cover plate 2, thereby the space of realizing first resonant rod 4 in coupled-wires and the cavity 1 is of coupled connections.
