Abstract

The invention discloses a kind of connector with shielding contact spring, comprise shielded conductor socket and shielded conductor plug; Shielded conductor plug and the mutual grafting of grafting ring be fixedly connected on shielded conductor socket; The inner chamber of grafting ring is provided with and holds spring groove; Hold spring groove and outer wall and contact the mutual snapping of spring with the shielding of locking tooth; The inwall of shielding contact spring is provided with has flexible upper Contact Tooth and lower Contact Tooth in opposite direction projection.The present invention to be connected to by locking tooth in the appearance spring groove on grafting ring due to shielding contact spring, and upper Contact Tooth and lower Contact Tooth can keep compact siro spinning technology with shielded conductor plug and shielded conductor socket, and shield effectiveness is good; And, upper Contact Tooth and lower Contact Tooth its own band flexible, when there is change in the space of shielded conductor socket and the grafting of shielded conductor plug, elastic force by himself keeps being connected with shielded conductor socket and shielded conductor plug, the phenomenon of disconnection can not be there is, fault-tolerant ability is high, limitation is little, and low cost of manufacture.

Description

A kind of connector with shielding contact spring
technical fieldthe invention belongs to technical field of electric connectors, be specifically related to a kind of connector with shielding contact spring.
background technologyin prior art, connector is generally made up of plug and socket two parts, when connector is in severe electromagnetic environment, for ensureing the quality of signal transmission, generally will carry out shielding processing to contact; The mode of contact being carried out to shielding processing is generally increase a metallic screening conductor again in the outside of contact outer insulator, and ensure electrical contact good between two shielded conductors, good for ensureing the Contact of metallic screening conductor, generally one of them shielded conductor to be designed to elastic construction, to ensure that this shielded conductor can form good contact with another shielded conductor.Common connector screening conductor elastic construction has sheet spring structure, string of a hat structure etc., and because these structures are all come by the structural evolution of jack contact, limitation is large; Meanwhile, also also exist that manufacturing cost is high, fault-tolerant ability is low, shield effectiveness is poor and the shortcoming such as complex structure.
summary of the inventionthe object of the invention is to solve prior art and have that limitation is large, manufacturing cost is high, fault-tolerant ability is low, shield effectiveness is poor and baroque technical problem, provide a kind of connector with shielding contact spring, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of connector with shielding contact spring of the present invention, it comprises shielded conductor socket and shielded conductor plug; Described shielded conductor plug and the mutual grafting of grafting ring be fixedly connected on shielded conductor socket; Its main points are that the inner chamber of described grafting ring is provided with appearance spring groove; Described appearance spring groove and outer wall contact the mutual snapping of spring with the shielding of locking tooth; The inwall of described shielding contact spring is provided with has flexible upper Contact Tooth and lower Contact Tooth in opposite direction projection.
The present invention is rational in infrastructure, novel in design, and because shielding contact spring to be connected to by locking tooth in the appearance spring groove on grafting ring, upper Contact Tooth and lower Contact Tooth can keep compact siro spinning technology with shielded conductor plug and shielded conductor socket, and shield effectiveness is good, structure is simple; And, upper Contact Tooth and lower Contact Tooth its own band flexible, when there is change in the space of shielded conductor socket and the grafting of shielded conductor plug, elastic force by himself keeps being connected with shielded conductor socket and shielded conductor plug, the phenomenon of disconnection can not be there is, fault-tolerant ability is high, limitation is little, and low cost of manufacture.The invention solves that prior art limitation is large, manufacturing cost is high, fault-tolerant ability is low, shield effectiveness is poor and baroque technical problem.
accompanying drawing explanationfig. 1 is structural representation cutaway view of the present invention;
Fig. 2 is the structural representation front view that the present invention shields contact spring;
Fig. 3 is the structural representation right view that the present invention shields contact spring;
Fig. 4 is the structural representation elevation view that the present invention shields contact spring.
In figure 1, shielded conductor socket 2, shielded conductor plug 3, grafting ring 4, shielding contact spring 5, hold spring groove 6, locking tooth 7, upper Contact Tooth 8, lower Contact Tooth
embodimentwith reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention it comprise shielded conductor socket 1 and shielded conductor plug 2; Described shielded conductor plug 2 and the grafting ring 3 be fixedly connected on shielded conductor socket 1 grafting mutually; Its main points are that the inner chamber of described grafting ring 3 is provided with appearance spring groove 5; Described appearance spring groove 5 and outer wall contact spring 4 snapping mutually with the shielding of locking tooth 6; The inwall of described shielding contact spring 4 is provided with has flexible upper Contact Tooth 7 and lower Contact Tooth 8 in opposite direction projection.
During use, shielding contact spring 4 is pressed in grafting ring 3, because the diameter of outer wall with the shielding contact spring 4 of locking tooth 6 is greater than the internal diameter of grafting ring 3 and is less than the internal diameter holding spring groove 5, deformation is there is when shielding contact spring 4 and pressing, when arriving appearance spring groove 5 place, shielding contact spring 4 recovers deformation and is connected to hold in spring groove 5; And elastic lower Contact Tooth just in time withstands on the end face of shielded conductor socket on shielding contact spring, shielding contact spring can be connected to firmly and hold in spring groove and can not shake; When inserting shielded conductor plug, the end face of shielded conductor plug just in time withstands in the upper Contact Tooth of shielding contact spring, when the space after shielded conductor socket and the grafting of shielded conductor plug changes, the upper Contact Tooth of shielding contact spring can keep, with the connection of shielded conductor plug, preventing the phenomenon of disconnection by the elasticity of self; During due to shielded conductor socket and the grafting of shielded conductor plug, the end face of shielded conductor socket can contact with lower Contact Tooth and compress lower Contact Tooth; Therefore, when grafting, shielded conductor socket and shielded conductor plug contact spring by shielding and achieve and conduct, thus ensure that the shield effectiveness of connector.
The present invention as elastic contact element, and relies on upper Contact Tooth and lower Contact Tooth to realize and the conducting of shielded conductor socket and shielded conductor plug by a shielding contact spring, and it is fixing to realize on shielded conductor socket by locking tooth; Structure of the present invention is simple, processing cost is low, fault-tolerant ability is strong, can realize the reliable contacts of shielded conductor socket and shielded conductor plug, overcome the deficiencies in the prior art in less space.
Result of use of the present invention is good, scope wide, is applicable to large-scale promotion and uses.

Claims (1)

1., with a connector for shielding contact spring, it comprises shielded conductor socket and shielded conductor plug; Described shielded conductor plug and the mutual grafting of grafting ring be fixedly connected on shielded conductor socket; It is characterized in that the inner chamber of described grafting ring is provided with and hold spring groove; Described appearance spring groove and outer wall contact the mutual snapping of spring with the shielding of locking tooth; The inwall of described shielding contact spring is provided with has flexible upper Contact Tooth and lower Contact Tooth in opposite direction projection;
