Description

The public connector of micro coaxial cable

Technical field:

The utility model relates to a kind of micro coaxial cable, refers to especially a kind ofly allow the enough torsion of acquisition between sleeve and blowout patche by excessively cooperating, and guarantees the public connector of the micro coaxial cable that the receiving angle of antenna can effectively be located.

Background technology:

In the utilization of signal transmission, for the coaxial cable of conducted signal, normally with the distance that connects intersite, signal frequency, required maximum deflection radius and in specific transmission and/or receiving system permissible space decide the standard of selecting for use.Generally speaking, the coaxial cable of use is long more, and frequency is high more, just needs big more external diameter, to prevent too much spillover.Tradition is applied to such as cable TV, the coaxial cable of aspects such as wide-band-message and microwave signal transmission, and its transmission range is in the scope of 50-1000 Foot, when external diameter is 0.25-1.At the short equipment (during about 6-24) of indoor transmissions distance requirement, less coaxial cable such as when it can be by use external diameter 0.1-0.14 is to overcome the narrow space and the restriction of bending radius.The coaxial cable of this type of less external diameter need use accurate micro connector, SMA for example, SMB and MCX etc.

With SMA type connector, it must be connected on the device such as reception with antenna or transmitting-receiving.The reception box (as: sound equipment, station selector, receiver etc.) that generally has antenna needs in use because of the corresponding angle of adjusting antenna of environment, till the signal that receives is the most stable.As shown in Figure 1, known SMA type connector has a fastening assembly 1, a spring assembly 2 and a connector body 3, when user's desire is adjusted the reception angle and during rotary antenna 4, to drive connector body 3 and spring assembly 2 rotations synchronously, spring assembly 2 during turning can be scraped the inner surface that injures wearing and tearing accepting hole 5, and then make spring assembly 2 provide enough torsion at fastening assembly 1 and 3 of connector bodies, thereby the locating effect of reduction antenna 4, this causes torsion deficiency therebetween, must be to overcome.In sum, need a kind of torsion of protecting forever to install uniformly at present, allow public connector have enough torsion, on unspecified angle, can effectively locate to guarantee antenna.

The utility model content:

Technical problem to be solved in the utility model is: at the above-mentioned deficiency of prior art, a kind of public connector of micro coaxial cable is provided, between sleeve and blowout patche, form and excessively cooperate, combining closely therebetween can guarantee that torsion is even, antenna can effectively be located at unspecified angle, and making transmits can effectively receive.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of public connector of micro coaxial cable, this public connector is connected with micro coaxial cable and female connectors respectively, this public connector comprises an annular blowout patche, an insulation assembly, this blowout patche has one first boring and one second boring, this insulation assembly is incorporated in first boring of this blowout patche, and the inside of this insulation component has a through hole, also comprises:

One sleeve made from plastic material, it has first accepting hole and second accepting hole;

One latch is incorporated in the through hole of described insulation assembly, and the inside of this latch has the first hole seat, a center conductor insertion and the second fixing hole seat for described female connectors that a center conductor for described micro coaxial cable inserts and fixes; And

One fastening assembly includes end, front and back, and one first interface portion and second interface portion, and this first interface portion is pressed on first accepting hole that is incorporated into this sleeve, and this second interface portion is pressed on second accepting hole that is incorporated into this sleeve; This leading section includes a threaded bore;

Woven mesh layer and the insulation material layer that described micro coaxial cable is arranged admitted in second boring of described annular blowout patche, this blowout patche has one first tubulated ends, one second tubulated ends and an interface portion, and this interface portion is incorporated in second accepting hole of this sleeve in the mode of tight contact.

Compared with prior art, the utility model has the advantages that: excessively cooperate owing to form between the sleeve of public connector and blowout patche, the combination of tight contact therebetween, when being combined with antenna, the blowout patche of public connector can rotate synchronously, and have uniform torsion when making antenna do the adjustment of suitable angle, effectively transmit to keep signal.
