Description
The utility model is relevant a kind of electric connector, especially a kind of electric connector with elastic conduction terminal.
Electric connector is normally used for impermanency ground and electrically connects various electronic building bricks, so that the transmission of the signal between electronic building brick to be provided when needed.United States Patent (USP) the 5th, 295 No. 839 and the 5th, 388, has disclosed a kind of elastic conduction assembly that utilizes separately and has reached the electric connector that electrically connects between two circuit boards for No. 997.Yet, the 5th, 295, the elastic component of the conductive component of the electric connector of No. 839 patents and non-elastic member are disconnected from each other opening, need each other insulation support member to be supported respectively, assembly is scattered, easily cause the puzzlement of fit on and be separated from each other easily, thereby the stability of telecommunication transmission can not get guaranteeing.And the 5th, 388, the elastic component of the conductive component of the electric connector of No. 997 patents is directly to contact with circuit board, not with the effective fixing of insulation support member, thereby break away from the non-elastic member in insulation support member and the conductive component easily, thereby interrupt telecommunication transmission between two circuit boards, make the stability of telecommunication transmission can not get guaranteeing.Therefore, be necessary these electric connectors are done an improvement in fact, to overcome the defective of aforementioned prior art.
The purpose of this utility model is to provide a kind of electric connector with height telecommunication transmission reliability.
The purpose of this utility model is achieved through the following technical solutions: this electric connector comprises insulating body and plurality of conductive terminals, and wherein insulating body is provided with parallel plurality of terminals accepting hole through between upper and lower surface.Conducting terminal comprises elastic connection part, Fixed Division and rubber-like elastic portion.Elastic portion is housed in the corresponding terminal accepting hole fully, elastic connection part and elastic portion one end are connected with group and protrude in the insulating body upper surface movably via terminal accommodation holes, the Fixed Division affixed with elastic portion and with terminal accommodation holes fixing mutually, and part protrudes in the insulating body lower surface.
Compared with prior art, advantage of the present utility model is: the mutual annexation of the elastic component of conducting terminal and non-elastic member can obtain preferable fixing effect by insulating body, so the transmission of the telecommunication between the electronic component that is undertaken by electric connector has obtained reliable assurance.Simultaneously, each member of conducting terminal is by an insulating body fixing, and component count reduces, and assembles also simpler.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that three-dimensional view is analysed in part of the present utility model.
Fig. 2 is a three-dimensional view of the present utility model.
Fig. 3 is a cutaway view of the present utility model.
Fig. 4 is the three-dimensional view of conducting terminal of the present utility model.
Please consult shown in Figure 1ly earlier, the utility model electric connector 1 includes insulating body 2 and plurality of conductive terminals 3.
Please consult Fig. 2 and Fig. 3 simultaneously, insulating body 2 have upper surface 20, with upper surface opposing lower surface 22 and from lower surface 22 middle parts inside recessed depressed part 26.The relative end walls 28 of depressed part 26 side direction is provided with the projection 21 that protrudes from lower surface 22 separately.Further convex with a roughly cylindrical reference column 23 on each projection 21.Depressed part 26 length respectively are provided with a row and run through the terminal accommodation holes 24 that upper and lower surface 20,22 extends in parallel in relative two side 25.As seen from the figure, each terminal accommodation holes 24 in the sidewall 25 is also unjustified in side direction with the terminal accommodation holes 24 in another sidewall 25.Each terminal accommodation holes 24 is provided with the channel part 240 that communicates with upper surface 20, communicate with channel part 240 and size 241 is extended the holding parts 242 that communicate with lower surface 22 downwards than the bigger resettlement section 241 of channel part 240 and from the resettlement section.The top of resettlement section 241 and channel part 240 joints are provided with the prevention wall 243 of inclination.Holding parts 242 sizes are more bigger than resettlement section 241, and are provided with some shallow slots 244 in the inwall near lower surface 22.
Please consult Fig. 4 simultaneously, conducting terminal 3 comprises elastic connection part 30, Fixed Division 32 and elastic portion 34.Elastic connection part 30 has cylindric contact site 300, the connecting portion 302 that the top is an arc and is positioned at contact site 300 and the pars intermedia 304 of connecting portion 302.Pars intermedia 304 diameters are more bigger and be provided with oblique outstanding shoulder 306 in itself and contact site 300 joints than contact site 300 and connecting portion 302.It is cylindric that Fixed Division 32 roughly is, and its outer surface is provided with flange 320 and the close end and the diameter jut 328 bigger than other position of some annular projections.Fixed Division 32 further is provided with the through hole 322 that runs through its length direction in it, through hole 322 comprises that the diameter appearance suitable with resettlement section 241 diameters meets portion 324 and connects with appearance that portion 324 communicates and port portion 326 that diameter reduces.In preferred embodiment as shown in the figure, elastic portion 34 is a coil spring, and it also can optionally make the elastic component of other version into.The internal diameter of elastic portion 34 is greater than the external diameter of connecting portion 302, and the other end is contained in to hold and connects in the portion 324 less than the internal diameter that appearance meets portion 324 is beneficial to that an end cover is overlying on connecting portion 302 peripheries.The top of the contact site 300 of elastic connection part 30 also can optionally be provided with and be sharp-pointed taper shape.
During assembling, elastic portion 34 1 ends of conducting terminal 3 are accommodated the appearance that is retained on Fixed Division 32 and are connect in the portion 324, and its other end then overlaps connecting portion 302 peripheries that are overlying on elastic connection part 30, so, finish the assembling of conducting terminal 3.Then, conducting terminal 3 inserts each terminal accommodation holes 24 from the lower surface 22 of insulating body 2, and corresponding shallow slot 244 interference engagement and jut 328 are stoped by the lower surface 22 of insulating body 2 in the flange 320 of Fixed Division 32 and terminal accommodation holes 24.Contact site 300 parts of elastic connection part 30 are housed in channel part 240, and it is outer electrically to contact with corresponding arrangements of electric connection that part protrudes in insulating body 2 upper surfaces 20.The shoulder 306 of pars intermedia 304 leans with the prevention wall 243 of resettlement section 241, thus the motion that stops elastic connection part 30 further to make progress.When the contact site 300 front end pressurizeds of elastic connection part 30 or when being subjected to the elastic-restoring force of elastic portion 34, elastic connection part 30 can and hold to connect in the distance that is limited in the portion 324 and move in resettlement section 241.Fixed Division 32 can optionally adopt existing mode to be soldered on the welded gasket of circuit board (not shown), thereby realizes the telecommunication transmission of circuit board and contact site 300 contacting electronic inter-modules.
