Description

The power supply rectangular connector

Technical field

The utility model relates to a kind of power supply rectangular connector, especially a kind of power supply rectangular connector of energy warm swap.

Background technology

Along with the next generation internet communication equipment progressively develops to miniaturization, modularization direction, installation site and the operating space of leaving various power supply communication interfaces for are more and more littler, require the corresponding various components and parts also must be more and more littler.At present, the modular power source interface that complete system plant uses has the like product of domestic DL series, CS42 series, DJL series and external ELCON company, and these product design volumes are relatively still big, it is more to take up room, and delivery cycle is long, costs an arm and a leg; Existing above product all can not be realized Hot Plug Capability simultaneously.Yet the modular power source of a new generation in case of emergency needs to carry out hot line job again, and therefore above product can not satisfy the requirement of complete system plant.

Summary of the invention

It is little and have a power supply rectangular connector of Hot Plug Capability and blind plugging function that the technical problems to be solved in the utility model provides a kind of volume.

For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of power supply rectangular connector, comprise plug and socket, described plug is by packing ring, the riveting cover, contact pin, collar, pin insulator and collar are formed, described socket is by the hole insulator, jack, collar, collar and stainless steel guide pillar are formed, the guide pillar of the hole insulator of described socket inserts in the guide pin bushing of connecting plug needle insulator, described contact pin comprises the 12# contact pin, 20# contact pin and 10# contact pin, described jack comprises 10# hat spring socket, 20# wire spring socket and 12# hat spring socket, the 12# contact pin of described plug, 20# contact pin and 10# contact pin respectively with the 12# of socket hat spring socket, the 20# wire spring socket is corresponding with the position of 10# hat spring socket.

Has length difference between the 12# contact pin of plug described in the utility model, 20# contact pin and the 10# contact pin.

The jack of socket described in the utility model is one sheet hyperboloid line spring and hat spring structure.

Be provided with the anti-mis-insertion structure between the pin insulator of plug described in the utility model and the hole insulator of socket.

Anti-mis-insertion structure described in the utility model is respectively to be provided with a triangle convex tendon on the guide pin bushing of the pin insulator two ends of plug, also respectively is provided with a triangular groove on insulator two ends, the hole guide pillar of described socket.

The integrated small-sized arrangement setting of plug unequally loaded signaling module described in the utility model.

The utility model compared with prior art, simple in structure, volume is less, easy for installation, use reliably, can realize warm swap and anti-misplug function.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.As Fig. 1-1,1-2 and Fig. 2-1, shown in the 2-2, the utility model power supply rectangular connector, comprise plug and socket, described plug is by packing ring 1, riveting cover 2,12# contact pin 3, collar 4,20# contact pin 5, pin insulator 6, collar 7 and 10# contact pin 8 are formed, described socket is by hole insulator 9,10# is preced with spring socket 10, collar 11,20# wire spring socket 12, collar 13,12# hat spring socket 14 and stainless steel guide pillar 15 are formed, the guide pillar of the hole insulator 9 of described socket inserts in the guide pin bushing of connecting plug needle insulator 6, the 12# contact pin 3 of described plug, 20# contact pin 5 and 10# contact pin 8 respectively with the 12# of socket hat spring socket 14,20# wire spring socket 12 is corresponding with the position of 10# hat spring socket 10.The jack of described socket is one sheet hyperboloid line spring and hat spring structure.

On the socket aperture insulator 9 two ends guide pillars of the present utility model a triangular groove is arranged respectively, same connecting plug needle insulator 6 two ends guide pin bushings also respectively have a triangle convex tendon, groove and convex tendon just in time cooperate when headstock plugs together, so connector can only plug together from a direction, thereby reach anti-mis-insertion and blind slotting function.

Another core technology of the present utility model is to have Hot Plug Capability, and this function is to realize by the length difference of contact pin contacting piece, and wherein 20# contact pin 5 is the shortest, is last conducting and disconnection at first when connector plugs; Next is a 12# contact pin 3, and the longest 10# contact pin 8 that is in this plug process, can take out arbitrary corresponding with it module under the situation that power supply does not cut off the power supply and pack into.

Principle of the present utility model is the use occasion according to power supply, to arrange by unequally loaded signaling module integrated small and be provided with, have three kinds of different contacts, be decided to be 20# line spring structure, 10# and 12# hat spring structure by concrete actual conditions, this structure plug is soft, reliability is high, vibration resistance resistance to impact and anti-hit are strong; Simultaneously these three kinds of positive contacts have differing heights, circuit is connected had sequencing, realize each module to be taken out or pack under the situation that complete machine do not cut off the power supply, thereby reach the requirement of warm swap; Another feature is insulator, and this has anti-misplug function when design, can realize blind plugging function under the guide pillar guide pin bushing mating reaction of two ends, and plug adopts when mounted to float and installs, and it is blind slotting to help connector; Adopt the inserts form simultaneously between stainless steel double-screw bolt 15 and the socket aperture insulator 9, socket is very convenient when mounted like this.

The utility model compared with prior art has the following advantages: (1) plug and socket adopt straight The formula of inserting connects, and has anti-mis-insertion and blind plugging function. Install and operate easily; (2) employing technology earlier The one sheet hyperboloid line spring that advances and hat spring structure have the reliability height, vibration resistance, resistance to impact The characteristics such as strong; (3) connector has Hot Plug Capability, and this point in the past product can't be realized. Therefore, can be widely used in the modular power source product of a new generation.
