Technical field
The present invention relates to a kind of male end contact and female end contact of the power connector that is used in printed board, installing and using, especially this power connector.
Background technology
The power connector that is suitable for the printed board installation is a kind of connector of bearing great current, transmit big electric current by the male end contact of its inner plug-in mounting and the cooperation that plugs together of female end contact, in the current delivery process, require male end contact and female end contact after plugging together, to electrically contact reliably, contact resistance is as much as possible little, require to have radiator structure simultaneously, reduce and better heat radiating effect, reach the purpose of control temperature rise with the caloric value that satisfies in the big current delivery process.At present, the power connector of this type has multiple version, the structure of its pairing male end, female end contact and both modes that plugs together also are not quite similar, but can both satisfy above-mentioned requirements basically, can select the power connector that suits according to the needs of different installation environments and use in use.Different structure has constituted multiple power connector with the male end that plugs together mode, female end contact and the assembling of pairing insulator, for the user selects to provide convenience.
Summary of the invention
The purpose of this invention is to provide a kind of new construction, meet the power connector male end contact that above-mentioned contact requires.Simultaneously, the present invention also provides a kind of new power connector female end contact that above-mentioned contact requires that meets, this female end contact can with the supporting use of male end contact of the present invention.
The technical scheme of power connector male end contact provided by the invention is: the male end contact of power connector, this contact is made of tabular public plug and a pair of space at rear portion, the parallel relative surface plate of its front portion, respectively to the both sides formation that overhangs, the lower limb of described two surface plates respectively is provided with at least one termination pin to this two surface plate from the tail end of tabular public plug.
Have at least one heat radiation straight joint that fore-and-aft direction is provided with on the described tabular public plug, described heat radiation straight joint runs through tabular public plug and extends to surface plate.
On the outer panel face of two surface plates, be equipped with the locking card platform.
The upper and lower edge of described two surface plates all has plugging together of the tabular public plug of protrusion corresponding edge and locatees the edge.
Described tabular public plug is made of an independent plate, and the front end of the rear end of independent plate and described two surface plates is connected as a single entity.
The bent plate parts that described tabular public plug is fitted by two side wall panels constitute, corresponding being connected as a single entity of front end of the two ends at bent plate parts rear portion and described two surface plates.
The technical scheme of power connector female end contact provided by the invention is: the female end contact of power connector, this contact comprises a pair of space, parallel relative surface plate, be oppositely arranged from the extended separately elastic cantilever of the mutually same end of these two surface plates, form the space that plugs together of the tabular public plug of male end contact between two elastic cantilevers, the free end of two elastic cantilevers inserts mouth away from forming the male end contact mutually; Be provided with at least one indent arc-shaped contact part by arm roots to free end on each elastic cantilever, indent arc-shaped contact part quantity on two elastic cantilevers equates, is oppositely arranged one by one, beeline between every group of relative indent arc-shaped contact part is all less than the thickness of the tabular public plug of supporting male end contact, when the male end contact insert described plug together the space after, two elastic cantilevers clamp the tabular public plug elasticity of male end contact; The lower limb of two surface plates respectively is provided with at least one termination pin.
At least one that all has the fore-and-aft direction setting on two elastic cantilevers cut apart the hole.
On the outer panel face of described two surface plates, be equipped with the locking card platform.
The leading portion at the upper and lower edge of described two surface plates partly is plugging together of protrusion elastic cantilever corresponding edge and locatees the edge, and the back segment part is connected as a single entity by a plate.
Adopt male end of the present invention, female end contact, can in the insulation shell of certain-length, assign a plurality of contacts, improved the packing density of contact in the insulation shell, realized integrated, for instrument, device miniaturization are laid a good foundation.Among the present invention, when the tabular public plug of male end contact insert the female end contact plug together the space after, by the indent arc-shaped contact part of two elastic cantilevers the tabular public plug of male end contact is implemented elasticity and clamps, realize current-carrying; When female end contact indent arc-shaped contact part reaches two or more; in male end; in the process that the female end contact plugs together; each organizes the sequencing difference that indent arc-shaped contact part elasticity clamps the male end contact; can realize like this to plug together really impose after putting in place clamp conducting the indent arc-shaped contact part with protection; preventing influences the elasticity clamping force at the initial stage of plugging together because of easily causing its indent arc-shaped contact part distortion; thereby guaranteed the reliability of male end contact electrical connection and less contact resistance, can prevent that further the caloric value that causes because of loose contact is unusual.
The main body of male end of the present invention, female end contact all is made of two surface plates that separate, and the afterbody of two contacts all is an opening-wide state, make the noncontact portion current-carrying face of two contacts be divided into two parts and be connected, in actual use, help electric current shunting and hollow and dispel the heat with printed board.
The male end contact connects the heat radiation straight joint of offering on its tabular public plug, on the one hand, after plugging together with the female end contact, the heat-dissipating space between male end, female end contact surface plate can be communicated with the formation heat dissipation channel, helps heat loss through convection in the current-carrying process; On the other hand, the integral slab face of tabular public plug can be divided into several parts, can improve effectively like this because of the integral slab facial disfigurement causes the situation with the local loose contact of female end contact and take place, thereby guarantee the reliability that male end, female end contact electrically contact after plugging together.
The female end contact offer on its two elastic cantilever cut apart the hole after, cut apart the hole indent arc-shaped contact part of elastic cantilever is divided into several short-terms contacts by long line contact on Width, the local loose contact or the local situation about not contacting that directly do not cause because of the long part of contact wire are improved, improved the reliability that male end, female end contact electrically contact after plugging together.
Male end, female end contact are provided with the locking card platform on its surface plate, all be to cooperate in order to insert at contact after the respective insulated housings with retaining draw-in groove on the insulation shell, reach to prevent that contact from withdrawing from the purpose of insulation shell, improve the reliability of electrical connection.
Male end of the present invention, female end contact are when pegging graft installation with corresponding insulation shell, utilize its upper and lower edge of surface plate plug together the location along with insulation shell on the slot inserting of relative set contact is held securely, therefore two surface plates also are fixed, strengthen, the termination pin is difficult for the displacement distortion, is convenient to the connector finished product and the smooth plug-in mounting of printed board that are assembled.
