Description

Coaxial connector

Technical field:

The utility model relates to a kind of coaxial connector.

Background technology:

General cable television system, wireless television system and common day cable TV system system are connected to distributor with backbone, export secondary main respectively by distributor again and are connected to user side, to receive the signal that television system was transmitted.Backbone includes coaxial cable, and its end is combined with coaxial connector, and coaxial connector is connected on the distributor.Existing coaxial connector, as shown in Figure 1, its mainly act on be make between coaxial baffle and connector body and center conductor with contact good combination between conductor to do the transmission of electric signal.Coaxial connector 100 includes sleeve body 101, and connector 102 is disposed at outside the sleeve body 101, reach fastener 103 and be disposed at outside the sleeve body 101, and fastener 103 is to utilize connector 102 that its formation is combined with 101 of sleeve body.Sleeve body 101 more comprises annular cylindrical part 104 and is disposed in the sleeve body 101, and ring sleeve 105 is disposed at 104 of sleeve body 101 and columnar members, and annular axle 106 coaxial being disposed in the sleeve body 101, and contact conductor 107 can be sleeved in the centre bore of annular axle 106, and with so that provide between connector 100 and distributor and be electrically connected.

Connector 100 can be inserted in the terminal of sleeve body 101 and form combination for the free end of coaxial cable 200, and the end of center conductor 201 is inserted in the endoporus 109 of contact conductor 107, to form the combination on electric.Insulator 202 is positioned at sleeve body 101 with 203 of exodermises; 204 of aluminium matter baffles are disposed between the outer surface and ring sleeve 105 of columnar member 104.The object of available crimping tool or similar functions apply a compression stress in the rear end of sleeve body 101 extending part 108 with 203 one-tenth sealings of the exodermis combination of the rear end extending part 108 that forces sleeve body 101 with coaxial cable 200, and the outer surface of ring sleeve 105 and aluminium matter baffle 204 contacting tightly with formation ground connection.

In coaxial cable and the coaxial connector combination following intrinsic problem is arranged, in the end of center conductor 201 endoporus 109 that is inserted in contact conductor 107 tightly (being the contact of rigidity) to rigidity, it can be because of environmental factor or other factors, vibrations that produce as the expanding with heat and contract with cold of air, wind or the rigidity of material own tired, thereby cause the chucking power generation of 107 pairs of center conductors 201 of contact conductor to get loose, so that can't form good being electrically connected therebetween, this will cause the reduction of electric signal transmission performance, and will be especially even more serious with Digital Transmission.For anti-kind situation here takes place, the staff must annual change this kind coaxial connector, but this solution will increase subsidiary cost and time.

The utility model content:

Technical problem to be solved in the utility model is: at the deficiencies in the prior art, provide a kind of coaxial connector, it can be effectively and the terminal fluid-tight engagement of the center conductor of coaxial cable, to guarantee being electrically connected reliably and with long-term.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: include sleeve body and contact conductor, sleeve body is admitted coaxial cable with coaxial manner, this coaxial cable includes center conductor, aluminium matter baffle, insulator and exodermis, and partly center conductor then is exposed to coaxial cable end; The contact conductor means is in sleeve body, and this contact conductor includes contact jaw, and described contact conductor also is provided with when coaxial cable inserts in the coaxial connector fully, and the outer surface of center conductor is inserted, and the latch female seat of combining closely with center conductor.

Described latch female seat includes can be in order to admit the plural elasticity finger of center conductor, and the outward-dipping one-tenth of described plural elasticity finger is coniform.Described latch female seat also is provided with the ring of the outside that can be linked in plural a brief period of time head, and forms the protuberance that sealing combines with center conductor under compression stress.

Compared with prior art, the utility model has the advantages that: the design of plural elasticity finger and ring on the latch female seat of contact conductor, make of the restriction of elasticity finger because of being encircled, and the elasticity finger centering heart conductor that can effectively press to contact conductor form mechanically with electric on combine, simultaneously the outer surface of protuberance applies compression stress and makes the surface, inside of protuberance form to seal with center conductor and combines, and is electrically connected reliably guaranteeing.
