Abstract

The utility model discloses a connector with a shielding contact spring. The connector comprises a shielding conductor socket and a shielding conductor plug. The shielding conductor plug is plugged with a plug ring fixedly connected on the shielding conductor socket. An inner cavity of the plug ring is provided with a spring-housing groove. The spring-housing groove is in lock joint with the shielding contact spring having latching teeth at the outer wall. The inner wall of the shielding contact spring is provided with upper contact teeth and lower contact teeth which are projecting oppositely and which are elastic. As the shielding contact spring is clamped in the spring-housing groove through the latching teeth, and the upper contact teeth and the lower contact teeth can maintain tight connection with the shielding conductor plug and the shielding conductor socket, the shielding effect is good. In addition, the upper contact teeth and the lower contact teeth are elastic, so that when a gap between the shielding conductor socket and the shielding conductor plug is changed, the upper contact teeth and the lower contact teeth can maintain connection with the shielding conductor plug and the shielding conductor socket through the elasticity, a phenomenon of disconnection is prevented, the fault-tolerant capability is high, the limitation is small and the manufacturing cost is low.

Description

A kind of connector with shielding contact spring

technical fieldthe utility model belongs to technical field of electric connectors, is specifically related to a kind of connector with shielding contact spring.

background technologyin prior art, connector is generally comprised of plug and socket two parts, when connector is in severe electromagnetic environment, for guaranteeing 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 to increase a metallic shield conductor in the outside of contact outer insulator again, and guarantee good electrically contacting between two shielded conductors, for guaranteeing that between metal shielded conductor, contact is good, generally one of them shielded conductor to be designed to elastic construction, to guarantee that this shielded conductor can form good contacting 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 that structural evolution by jack contact comes, limitation is large; Meanwhile, 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 purpose of this utility model is to solve prior art to have that limitation is large, manufacturing cost is high, fault-tolerant ability is low, shield effectiveness is poor and baroque technical problem, provides 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 utility model, it comprises shielded conductor socket and shielded conductor plug; Described shielded conductor plug is pegged graft mutually with the grafting ring being 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 and is projection in the other direction and has flexible upper Contact Tooth and lower Contact Tooth.

The utility model is rational in infrastructure, novel in design, because shielding contact spring is connected in the appearance spring groove of pegging graft on ring by locking tooth, upper Contact Tooth can keep being closely connected with shielded conductor plug and shielded conductor socket with lower Contact Tooth, and shield effectiveness is good, simple in structure; And, upper Contact Tooth and lower Contact Tooth self are with flexible, when changing appears in the space of shielded conductor socket and the grafting of shielded conductor plug, can keep being connected with shielded conductor socket and shielded conductor plug by the elastic force of himself, can there is not the phenomenon of disconnection, fault-tolerant ability is high, limitation is little, and low cost of manufacture.The utility model has solved 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 the utility model structural representation cutaway view;

Fig. 2 is the structural representation front view of the utility model shielding contact spring;

Fig. 3 is the structural representation right view of the utility model shielding contact spring;

Fig. 4 is the structural representation elevation view of the utility model shielding contact spring.

In figure 1, shielded conductor socket 2, shielded conductor plug 3, the ring 4 of pegging graft, 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, it comprises shielded conductor socket 1 and shielded conductor plug 2 the utility model; Described shielded conductor plug 2 is pegged graft mutually with the grafting ring 3 being fixedly connected on shielded conductor socket 1; 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 the mutual snapping of spring 4 with the shielding of locking tooth 6; The inwall of described shielding contact spring 4 is provided with and is projection in the other direction and has flexible upper Contact Tooth 7 and lower Contact Tooth 8.

During use, shielding contact spring 4 is pressed in the ring 3 of pegging graft, because the diameter of outer wall with the shielding contact spring 4 of locking tooth 6 is greater than the internal diameter of the ring 3 of pegging graft and is less than the internal diameter that holds spring groove 5, when pressing, shielding contact spring 4 there is deformation, arrive while holding spring groove 5 place, shielding contact spring 4 recovers deformation and is connected to hold in spring groove 5; And elastic lower Contact Tooth 8 just in time withstands on the end face of shielded conductor socket 1 on shielding contact spring 4, make shielding contact spring 4 can be connected to firmly to hold in spring groove 5 and can not shake; When inserting shielded conductor plug 2, the end face of shielded conductor plug 2 just in time withstands in the upper Contact Tooth of shielding contact spring 47, when shielded conductor socket 1 and shielded conductor plug 2 grafting Hou spaces change, the upper Contact Tooth 7 of shielding contact spring 4 can, by the elasticity maintenance of self and being connected of shielded conductor plug 2, prevent the phenomenon of disconnection; During due to shielded

conductor socket

1 and 2 grafting of shielded conductor plug, the end face of shielded conductor socket 1 can contact and compress lower Contact Tooth 8 with lower Contact Tooth 8; Therefore, when pegging graft, shielded conductor socket 1 and shielded conductor plug 2 contact spring 4 by shielding and have realized and conducting, thereby have guaranteed the shield effectiveness of connector.

The utility model 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 realizes fixing on shielded conductor socket by locking tooth; The utility model is simple in structure, processing cost is low, fault-tolerant ability is strong, realizes shielded conductor socket in can compare little space to contact with the reliable of shielded conductor plug, has overcome the deficiencies in the prior art.

The utility model result of use is good, scope is wide, is applicable to large-scale promotion and uses.
