Summary of the invention
In order to address the above problem, the utility model provides a kind of simple in structure, circuit connector that the scope of application is wide, safe and reliable.
To achieve these goals, the utility model is mainly solved by the following technical programs: a kind of circuit connector, comprise base, be provided with jack in one end of base, jack is plugged with contact pin, is provided with the adapter sleeve that is complementary with jack in the described jack, and adapter sleeve comprises by elastic conducting material makes cylindrical body, the sidewall of body is provided with the opening b that axially runs through sidewall, and described contact pin is plugged in the described body.
As preferably, the sidewall of above-mentioned body is provided with interior concaved circular cambered surface.
As preferably, extend axially along the central shaft of body on the sidewall of above-mentioned body and be evenly distributed with several elongated holes, form brace between the adjacent elongated hole.
As preferably, the above-mentioned lateral wall at base and the same end of jack is provided with cascaded surface, lateral wall one end of described body is provided with several limit pin that axially extends to the body other end along the body central shaft, described limit footmuff is connected on the lateral wall of described base, described limit pin is socketed with upper cover outward, upper cover is provided with through hole, and the diameter of through hole and the diameter of described contact pin are complementary.
As preferably, the above-mentioned lateral wall at base and the same end of jack is provided with cascaded surface, lateral wall one end of described body is provided with several limit pin that axially extends to the body other end along the body central shaft, described limit footmuff is connected on the lateral wall of described base, described limit pin is socketed with upper cover outward, upper cover is provided with through hole, and the diameter of through hole and the diameter of described contact pin are complementary.
The utility model is by being provided with adapter sleeve in jack, adapter sleeve comprises by elastic conducting material makes cylindrical body, the sidewall of body is provided with the opening b that axially runs through sidewall, adapter sleeve is socketed in the jack, when contact pin inserts body so, body is laterally strutted, can not cause what contact with contact pin is the inclined-plane, but vertical plane contacts with the lateral wall of contact pin, has realized plane-plane contact, increased contact area, thereby can either use in the circuit of little electric current, also can use in the circuit with large electric current, the scope of application is wider, the increasing of current carrying capacity has guaranteed fail safe simultaneously.

Embodiment
Below in conjunction with accompanying drawing 1-8, the embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of circuit connector, comprise base 1, be provided with the jack 2 for grafting contact pin 5 in the end of base 1, the other end of base 1 is used for connecting electric wire.Be provided with the adapter sleeve 6 that is complementary with jack 2 in the jack 2 of base 1, adapter sleeve 6 comprises by elastic conducting material makes cylindrical body 7, and the sidewall of body 7 is provided with the opening 15 that axially runs through sidewall.During use, above-mentioned contact pin 5 is socketed in the described body 7.
For the difficulty of processing that can reduce jack 2 and contact pin 5 with make precision, the sidewall of body 7 is provided with interior concaved circular cambered surface 8, inserts body 7 when interior at contact pin 5, and contact pin 5 struts interior concaved circular cambered surface 8, has guaranteed equally the realization plane-plane contact, has guaranteed contact area.
