Description
Technical field
The present invention relates to the connector with short circuit defencive function for electric signal transmission.
Background technology
Some has the connector of defencive function, require after it is separated with intermateable connector, each stratum's part is all in short circuit state, existing a kind of connector with short circuit defencive function " has the connector, 4-pin of short circuit defencive function " disclosed in Chinese patent CN202550146U, comprise the insulating element being provided with two pairs of contacts, insulating element is provided with between two of often pair of contact contacts the contact that a front end extends to insulating element front end face and is installed with hole, contact is installed with in hole and is provided with the contact of rear end by stage clip and insulating element resilient engagement, flange on the contact that when front end of contact is moved outside and left and right is arranged is electrically connected by sphere short-circuit structure top press contacts, after move time with this, flange on contact is separated, insulating element comprises the front insulator of split setting and rear insulator, before the front end corresponding inserted of each contact is arranged on front insulator in contact providing holes, in the rear contact providing holes that the rear end corresponding inserted of each contact is arranged on rear insulator, the front end face top of the flange on contact is pressed on the rear end face of front insulator, the rear end face top of flange is pressed on the front end face of rear insulator, the rear end that each contact is installed with hole all extends in rear insulator.In use, this connector coordinates with intermateable connector, intermateable connector is installed with hole place corresponding to contact and is provided with push rod, when plugging together, push rod stretches into the front end that contact is installed with pressure contact in top in hole, the active force making contact overcome stage clip moves backward, and at this moment contact can depart from the flange on contact, removes the short circuit between contact.Existing this short-circuit connector Problems existing is: 1, the front end of contact is spherical structure, the flange coordinated with it is also spherical structure, that is conducted electricity by point cantact between contact and flange, contact area is little, contact resistance is large, stability is not high, and spherical structure manufacture is comparatively complicated in addition, can increase the cost of product; 2, the flange of hemispheric contact and arc-shaped cannot realize locating, and causing contact very difficult when assembling, being not easy to be seated rapidly, assembling expends time in longer; 3, contact be subject to push rod top pressure and move backward time without relatively-stationary tracks, easily there is deflection in spring, contact, likely can have an impact to adjacent short circuit contact assembly.
Summary of the invention
The object of the present invention is to provide a kind of connector with short circuit defencive function, to solve in prior art the problem causing connector to assemble difficulty because contact is not easily located.
In order to solve the problem, technical scheme of the present invention is:
A kind of connector with short circuit defencive function, comprise the insulating element being provided with at least one pair of contact, insulating element comprises the removable front insulator that is assembled together and rear insulator, the arranged direction defining adjacent two contacts is left and right directions, each contact is provided with flange, connector also comprises the contact that front end presses short circuit to coordinate by short-circuit structure with the flange top of corresponding about two adjacent layouts, in on both sides are respectively arranged with up and down of contact on described front insulator, side, lower location, on, interval, side, lower location is oppositely arranged, contact is spacing to be up and down held in, between side, lower location.
The upper and lower side of described contact respectively with side, described upper and lower location in the longitudinal direction slide-and-guide coordinate.
Side, described upper and lower location is plane, and the upper and lower side of described contact is the plane be arranged in parallel with side, described upper and lower location.
Described rear insulator comprises and to arrange with described contact one_to_one corresponding and to supply the insulating case of each contact rear end positioning and plug-in mounting respectively, spacing cooperation is pressed with corresponding flange top respectively in the front end of described each insulating case, between the opposite flank of what each contact left and right was spacing be held in corresponding adjacent two insulating cases, lead in the longitudinal direction with the opposite flank of adjacent two insulating cases respectively and be slidably matched in the left and right side of described contact.
The rear end of described each contact is all by stage clip and rear insulator resilient engagement, and described rear insulator also comprises the pressing plate being fixedly arranged on each insulating case rear end, and the front end of described pressing plate is installed with the lead for each stage clip guiding suit.
Beneficial effect of the present invention is: contact front end presses short circuit to coordinate by short-circuit structure with corresponding about two the flange tops arranged, front insulator arranges be oppositely arranged upper respectively in the both sides up and down of contact, side, lower location, contact by positioning clamping in upper, between side, lower location, the flange that left and right is arranged so in other words supports about contact, on, upper then to contact of side, lower location, the spacing cooperation in downside, before rear insulator is assemblied on insulator before, contact corresponding flange and on, relative with contact fixing under the effect of side, lower location, directly rear insulator is assemblied on front insulator, the assembling of whole connector is simple and convenient.
Further, side, upper and lower location constitutes the first guide rail that guide direction extends along the longitudinal direction, the opposite flank of adjacent two insulating cases constitutes the second guide rail that guide direction extends along the longitudinal direction, this connector is when plugging together with intermateable connector, by the push rod thrusting action on intermateable connector, contact overcomes stage clip active force and then moves, and be held between first, second guide rail because contact is directed to, so the movement locus of contact is fixing and relatively independent, can not have an impact to other parts, reliability is higher.
