Abstract
The invention provides an electric connector having a short circuit function. The electric connector comprises a plug and a socket. The socket comprises a socket shell (9), a socket base (10) and two jacks (7). The plug comprises a plug shell (1), a plug base (3) and two pins (2). The socket also comprises an elastomer and a short circuit module. The short circuit module can move in a manner of being perpendicular to the plugging direction of the plug and the socket under the elastic effect of the elastomer so as to be electrically contacted with the two jacks (7) simultaneously and realize short circuit connection between the two jacks (7). The plug shell (1) of the plug pushes the short circuit module in the plugging process of the plug and the socket so that the two jacks (7) are enabled to be insulated from the short circuit module. According to the electric connector, the electric connector can be used for electrical connection between two sets of equipment having floating on the axial position so that the structure is compact, the boundary dimension is small and the reliability is high.
Description
Technical field
The invention belongs to connector technique field, especially belongs to the electric connector with short-circuit function between a kind of contact.
Background technology
As electronic equipment is more and more accurate, part electronic equipment needs connector body mounted thereto to plug together between the contact of front socket with short-circuit function in plug, prevents electrostatic or other electromagnetic interference from causing to damage to electronic equipment；And work as plug dock with socket plug together after need insulation between the contact of socket, with normal transmission signal.At present, the adapter with short-circuit function is mostly by the way of short board or short-circuit ball.
Short board mode is mainly designed with short circuit metal plate in socket butt end, there is the spliced eye corresponding with contact on short circuit metal plate, and on the contact connected with spliced eye, design resilient " spear " shape position, short board is axially promoted when docking by plug, is made " spear " the shape location contacts of spliced eye on short board and contact or is separated the short circuit or insulation realized between contact.
Short-circuit ball mode is mainly a certain ad-hoc location of contact in socket and arranges outwardly flange.Between two relative contact flanges, the ball of spring and short circuit connection is set along contact, when docking by plug, moves axially short-circuit ball, make to contact between short-circuit ball and contact flange and disconnect short circuit or the insulation realized between contact.
The above-mentioned conventional adapter with short-circuit structure is all axially to promote short block to realize the short circuit between socket contact or insulation by plug or plugging together for socket, which requires to the relative axial position between plug and socket more strictly, just reliably cannot use in the case where two equipment room axial locations exist and float.For example, " spear " short-circuit structure of short board mode shown in Fig. 1, guided by 21 for contact can radially-inwardly elastic shrinkage " spear " position, part guided by 60 is short circuit metal plate, when plug is not docked in place completely with socket, contact is m with the most short insulation distance of short board, and which is less than the insulation distance n of design code, product decreasing insulating is caused, or even unexpected short circuit phenomenon occurs.
The content of the invention
The purpose of the present invention is：For the existing electric connector with short-circuit structure using axially i.e. plug moves short block with the direction that plugs together of socket, the direction for plugging together direction that a kind of radial direction i.e. vertical header is provided with socket promotes short block to realize the electric connector of short circuit, can be used for the electrical connection that there are two equipment rooms for floating in axial location.
