Abstract
The utility model discloses an electrical plug-in connector. According to the connector, an original mode that a plug outer conductor and a socket outer conductor are in axial contact through a coupling element is changed; and the inner part of the plug outer conductor is provided with cylindrical elastic contact element with an annular boss, the front part of the socket outer conductor is provided with a stepped hole, and the elastic contact element and the inner side wall of the stepped hole of the socket outer conductor are in radial tight and elastic contact in the process of assembly. By adopting the electrical plug-in connector, the passive intermodulation performance of the connector in the butting process is enhanced, and the contact reliability and durability of the connector are substantially improved.
Description
Technical field
The utility model relates to technical field of electric connectors, especially a kind of improved electric connectors, and this connector has improved reliability and the durability of original connector interworking contact.
Background technology
The technical scheme that improves electrical plug-in connector passive inter-modulation performance is disclosed in China ZL03103882.4.This scheme arranges a disc spring shape and has flexible coupling unit between the outer conductor of two linkage units of connector, and two outer conductors all form closed ring contact surface with coupling unit, with this, improve the passive inter-modulation performance of connector.
In actual application, find, this structure is controlled higher to the tolerance of two outer conductors and coupling element: when design, calculate size and the tolerance of two outer conductors, analyze the size and the tolerance that obtain coupling element; In the actual course of processing, if the tolerance of two outer conductors is overproof, be assembled into and be easy to occur two situations that the cooperation space between outer conductor is too small, coupling unit is crushed out of shape and lost efficacy after product, or the cooperation space between two outer conductors is excessive, coupling unit contacts with two outer conductors and insufficiently cannot meet passive intermodulation index.
Utility model content
The purpose of this utility model is to provide improved electric connectors, on original connector construction basis, an elastic contact element that adopts the different ways of contact is set, and improves passive inter-modulation performance or the third order intermodulation performance of electrical plug-in connector.
In order to achieve the above object, described electrical plug-in connector adopts following technical scheme:
A kind of electrical plug-in connector, pin connector and socket connector, consist of, feature is that pin connector head is provided with elastic contact element, and it is cylindric that elastic contact element is, its front portion is divided into a plurality of elastic cantilevers by several axial profile grooves, and rear portion is circular contact ring; The cantilever beam of elastic contact element axially stretches out from contact ring, and cantilever beam front end is provided with the radially outward annular contact of projection; Elastic contact element is by the contact ring at rear portion and the outer conductor interference fit of pin connector; Socket connector front portion is provided with stepped hole, when pin connector and socket connector are pegged graft, and the annular contact of elastic contact element front portion and the tight Elastic Contact of stepped hole madial wall in socket outer conductor.
Described elastic contact element is made by resilient copper alloy.
Described ring-type contact contacts with socket stepped hole madial wall as the line contact of ring-type or face contact.
Contrast prior art ZL 03103882.4, the ring-type contact of the utility model elastic contact element and the tight Elastic Contact of madial wall of the socket stepped hole in socket outer conductor, and be line contact or the face contact of ring-type, not only can increase substantially passive inter-modulation performance or the third order intermodulation performance of electrical plug-in connector, and can improve the power of electrical plug-in connector.
Accompanying drawing explanation
Fig. 1 is the disclosed electrical plug-in connector structural representation of Chinese ZL03103882.4;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model socket connector structure schematic diagram;
Fig. 4 is the utility model pin connector structural representation;
Fig. 5 is the utility model elastic contact element structural representation.
Embodiment
Below in conjunction with accompanying drawing, improved electric connectors described in the utility model is described in further detail:
Consult Fig. 1, disclosed electrical plug-in connector in China ZL03103882.4, when plug and socket plug together after locking, be difficult to guarantee effective close contact between plug outer conductor and socket outer conductor, therefore, apply the electrical plug-in connector of so fast lock connected mode, can not guarantee that it has good passive inter-modulation performance or third order intermodulation performance.
Consult Fig. 2-5, the utility model is comprised of pin connector 1 and socket connector 2, pin connector 1 head is provided with elastic contact element 14, elastic contact element 14 is cylindric, its front portion is divided into a plurality of elastic cantilevers 144 by several axial profile grooves 142, and rear portion is circular contact ring 143; The cantilever beam 144 of elastic contact element 14 axially stretches out from contact ring 143, and cantilever beam 144 front ends are provided with the radially outward annular contact 141 of projection; Elastic contact element 14 is by the contact ring 143 at rear portion and outer conductor 11 interference fit of pin connector; Socket connector 2 front portions are provided with stepped hole 221, and pin connector 1 is pegged graft with socket connector 2, the annular contact 141 of elastic contact element 14 front portions and the tight Elastic Contact of stepped hole 221 madial wall in socket outer conductor 22.The line that the ring-type contact 141 of elastic contact element 14 front portions is ring-type with socket stepped hole 221 madial walls contacts or face contact.
The utility model is good in order to ensure contact between two outer conductors, improves the passive inter-modulation performance of electrical plug-in connector, and the utility model is set up an elastic contact element 14 between plug outer conductor and socket outer conductor.Elastic contact element 14 is arranged between plug outer conductor 11 and socket outer conductor 22, and elastic contact element 14 is fixed in plug outer conductor 11 by rear portion contact ring 143 interference fit.When plugs and sockets interworking is locked, elastic contact element 14 stretches into the stepped hole 221 and the tight Elastic Contact of its madial wall in socket outer conductor 22 by the ring-type contact 141 of anterior elastic cantilever.Elastic contact element 14 is made by resilient metal, for example a kind of suitable copper alloy.
