Embodiment

Fig. 2 A shows the design of the terminals 200 of compression connector in the exemplary embodiment.With first section 202 and second sections 204 form, terminals 200 comprise two cantilever segments.The terminals 200 of design comprise recurvate beam section 204 (against frictional direction), keep gap 206 simultaneously between beam section 202 and beam section 204.By having this gap 206, make cantilever beam section owing to making terminals 200, promptly beam section 204 is not in the exemplary embodiment interfered with molding cutter, and terminals 200 just are easy to make.

Terminals 200 further comprise shaft portion and the contact sweep 210 with the 3rd beam section 208 forms that is arranged between beam section 202 and the beam section 204.Beam section 208 keeps in the mode that is roughly parallel to the compression stress direction that is applied on the contact sweep 210.Terminals 200 also have weldering tail (solder tail) 212.

Terminals 200 comprise maintenance barb 214, keep barb 214 to be arranged between the first beam section 202 and the weldering tail 212.Fig. 2 B shows the terminals 200 that have in the exemplary embodiment with regular spaces barb 214 at interval.In the exemplary embodiment, terminals 200 are by electric conducting material such as beryllium copper or phosphor bronze, and/or gilding is made.In different embodiment, other electric conducting material also can be used to make terminals.

Fig. 3 shows the cross-sectional view of the mold insulation housing 300 of terminals 200 in the exemplary embodiment.In the exemplary embodiment, housing 300 is to be made by common engineering plastics such as polyphenylene sulfide (PPS) and liquid crystal polymer (LCP).In different embodiment, other non-conducting material can be used to make housing.

In Fig. 3, see two

different chambeies

302 and 304, wherein hold beam section 204 and beam section 202 (comparing) respectively with Fig. 2.On the sidewall in chamber 304, have groove/recess 306, keep barb 214 to be pushed into and be assembled in each groove 306.After in being mounted to groove 306, barb 214 is being pressed the wall of groove 306, to guarantee that terminals 200 are in housing 300.

Fig. 4 A shows in the exemplary embodiment, and load is applied to the compression connector 400 that assembles before the contact sweep 402 of terminals 404.Terminals 404 are arranged in the housing 406.When not having load to be applied on the terminals 404,

beam section

412 and 414 remains static, and promptly terminals 404 are indeformable.

Compression connector 400 after Fig. 4 B shows on the contact sweep 402 that load in the exemplary embodiment is applied to terminals 404.By with PCB 410 vertically by being pressed on the contact sweep 402, load is applied on the contact sweep 402.By utilizing screw rod, latch or other fastener that PCB 410 is fixed on the compression connector 400, this load keeps constant substantially.In the time of imposed load, in the exemplary embodiment, will interact to produce reaction force with housing 406 by pushing 406, two beam sections 412 of housing and 414.Thereby load is distributed between two beam sections 412 and the beam section 414, and each beam section is served as the cantilever of each strong point 415,413 on the housing 406.

Compare with relying on single bent beam, terminals 404 in the exemplary embodiment can produce bigger compression stress, can also prevent terminals 404 quilts weight and permanent deformation excessively.The feature of compression connector 400 is, when load is applied on the contact sweep 402, by by being pressed on the housing, as the beam section 412 of cantilever segment and 414 and housing 406 interact.In the exemplary embodiment, terminals 404 and housing 406 replenish mutually so that manufacture method practicable and that save cost to be provided, and are used for as close interval connector.

Fig. 5 shows the perspective view that is arranged side by side a plurality of terminals 502 in housing 504 in the exemplary embodiment, and part is a sectional plane.In this embodiment, two row chambeies are formed in the housing 504 as 506,508 and pass this housing 504.When load was applied on the terminals, by pushing housing, each chamber that is contained in of each terminals interacted as cantilever segment and housing 504 as 512 and 514 as two beam sections in 506,508.

In this embodiment, each terminals tilts as the shaft portion as beam section 510 forms between 512,514 a little as 502 two the beam sections that are arranged on, but keeps the beam section as 510 directions with respect to the compression stress almost parallel on the terminals 502 (comparison diagram 4A) and B)).

It will be apparent to one skilled in the art that at the present invention who illustrates in a particular embodiment and can make multiple change and/or modification, and do not break away from the spirit and scope of broad description of the present invention.Therefore, generally speaking, these embodiment are non-limiting for illustrative.

For example, the present invention be can understand and the terminals as shown in exemplary embodiment and/or the shape of housing are defined as.But other shape can be used among the different embodiment, comprises difform cantilever segment and/or contact section and/or shaft portion and/or weldering rear and/or chamber.

In addition, can understand in different embodiment, each housing can have the terminals of different numbers.
