Description

The power module connector

Technical field

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

Background technology

Fast development along with the modern science and technology technology, equipment of new generation is gradually to microminiaturized, modularization future development, serviceability and volume size requirements to various components and parts are more and more higher, the competition in market is more and more fierce simultaneously, the cost that reduces complete machine must reduce the cost of various components and parts, the most of car round contact that adopts of the power module interface that tradition is used, this series products overall volume is large, Costco Wholesale is high; And can bear large electric current in the traditional product and can keep good elasticity again, simultaneously can guarantee that also the product of hot plug is comparatively rare, and the power module of a new generation in case of emergency needs to carry out hot line job, so traditional product can not satisfy the requirement of complete system plant.

Summary of the invention

The technical problems to be solved in the utility model provides that a kind of volume is little, current-carrying is large and have the power module connector of Hot Plug Capability.

For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of power module connector, comprise insulator, and in the described insulator shell fragment is housed, described shell fragment lower ending opening place is incorporated with reed, and the Symmetrical Circular Arc of reed front end partly forms the V character form structure.

Shell fragment described in the utility model is the stainless steel shell fragment, and its lower ending opening place is provided with the shell fragment boss.

Reed described in the utility model is the copper alloy reed of high conductivity, and its middle and lower part has strip columnwise contact groove, is provided with limit point at the cell body middle part.

One end of insulator described in the utility model is provided with back-off.

The inboard of insulator described in the utility model has radiating groove.

The utility model compared with prior art, and is simple in structure, volume is small and exquisite, and not only current-carrying is large, and has Hot Plug Capability, has greatly improved the contact reliability of power module connector.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Such as Fig. 1-1 to shown in Fig. 1-9, the power module connector of the utility model embodiment one adopts the soldering of printed boards structure, comprises insulator 3, and shell fragment 1 is housed in the insulator 3, shell fragment 1 lower ending opening place is incorporated with reed 2, and the Symmetrical Circular Arc of reed 2 front ends partly forms the V character form structure.Wherein, shell fragment 1 is the stainless steel shell fragment, and its lower ending opening place is provided with shell fragment boss 11; Reed 2 is the copper alloy reed of high conductivity, and its middle and lower part has strip columnwise contact groove 21, is provided with limit point 22 at the cell body middle part; One end of insulator 3 is provided with back-off 31, and the inboard of insulator 3 has radiating groove 32 simultaneously.

To shown in the 2-9, the power module connector of the utility model embodiment two adopts the printed board bolt fastening structure such as Fig. 2-1, and reed 2 ' is provided with bolt connecting hole.

During the utility model embodiment one assembling, shell fragment 1 struts oral area by frock, again reed 2 shell fragment of packing into, after the limit point that checks the boss of shell fragment oral area and reed is seated, the insulator 3 of packing into together makes the back-off 31 of insulator buckle the shell fragment end face and gets final product.During the utility model embodiment two assembling, shell fragment 1 struts oral area by frock, again the reed 2 ' shell fragment 1 of packing into, after the limit point that checks the boss of shell fragment oral area and reed is seated, the insulator 3 of packing into together makes the back-off 31 of insulator buckle the shell fragment end face and gets final product.

Power module connector of the present utility model has following characteristics:

A) the few applicability of product parts is good

That product design gets is simple in structure, overall volume is little, bear current-carrying reaches greatly the advantages such as perfect heat-dissipating, applicable to the occasion that requires little space, large electric current.

B) adopt shell fragment to provide elastic structure to the reed of current-carrying

Shell fragment adopts the good stainless steel material of elasticity, provides stable elastic pressure to reed, allows reed contact with copper bar more reliable, so that product has the characteristics such as vibration resistance, resistance to impact are strong.

C) the reed front portion is " V " character form structure

Reed adopts the high copper alloy of conductance, can bear large current-carrying; The reed front portion is the V character form structure, and this structure is the discharge prevention part, and circular arc portion is to avoid the wedge angle discharge, so that product has the hot-swappable characteristics.

D) reed adopts the contact of many strip columnwises structure

Theoretical according to plane contact, the contact reliability of product can be better protected in many row contacts.

In sum, the utility model product structure is simple, installs and operates easily; Shell fragment provides stable elastic pressure to reed, allows reed contact with copper bar more reliable, so that product has the characteristics such as vibration resistance, resistance to impact be strong; Product has Hot Plug Capability, and this point is the product function that can't realize in the past.
