Description
Technical field
The invention belongs to connector technique field, the electric connector with short-circuit function between a kind of contact is especially belonged to.
Background technique
As electronic equipment is more and more accurate, part electronic equipment need connector body mounted thereto with plug
Plugging together has short-circuit function between the contact of front socket, prevent electrostatic or other electromagnetic interferences from damaging to electronic equipment；
And insulate between the contact for needing socket after plug is docked with socket and plugged together, with normal transmission signal.Currently, having short
The connector of road function is mostly by the way of short board or short-circuit ball.
Mainly in socket butt end, design has short circuit metal plate to short board mode, has on short circuit metal plate and contact phase
Corresponding spliced eye, and flexible " spear " shape position is designed on the contact to connect with spliced eye, when being docked by plug
It is axial to push short board, make spliced eye on short board and " spear " the shape location contacts of contact or separate realization contact it
Between short circuit or insulation.
Short-circuit ball mode is mainly that the flange outwardly protruded is arranged in a certain specific position of contact in socket.In two phases
Pair contact flange between, along contact setting spring and short circuit connection ball, moved axially when being docked by plug short
Road ball makes to contact and disconnect the short circuit or insulation realized between contact between short-circuit ball and contact flange.
The above-mentioned common connector with short-circuit structure is all axially to push short-circuit mould by plug or plugging together for socket
Block realizes the short circuit or insulation between socket contact, requires the relative axial position between plug and socket more tight
Lattice just can not be used reliably in the case where two equipment room axial positions exist and float.For example, short board mode shown in Fig. 1
" spear " short-circuit structure, be guided by 21 contact can radially-inwardly elastic shrinkage " spear " position, guided by 60
Part be short circuit metal plate, when plug does not dock in place completely with socket, contact and short board it is most short insulate away from
From for m, it is less than the insulation distance n of design code, causes product decreasing insulating, or even unexpected short circuit occur now
As.
Summary of the invention
The purpose of the present invention is: using axial for the existing electric connector with short-circuit structure is plug and socket
The shortcomings that plugging together direction movement short block, the direction promotion for plugging together direction for providing a kind of radial direction i.e. vertical header and socket are short
