Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model contact pin.
Fig. 2 is that the A-A sectional plane schematic diagram in connector case body is arranged in contact pin in Fig. 1.
Specific embodiment
The utility model provides the contact pin for being applied to photovoltaic connector.Below in conjunction with attached drawing to technical solutions of the utility model
It is described in detail, so that it is more readily understood and grasps.
It applied to the contact pin of photovoltaic connector, as depicted in figs. 1 and 2, is fixed in connector shell 1, is used for and sleeve
Electric connection is carried out, contact pin, which is set in connector shell 1 and carries out mating with sleeve, belongs to common sense, and the connector is omitted in this case
The connector shell of shell 1 and sleeve matches map interlinking, and this case is mainly that the mating proposed between contact pin and connector shell 1 is closed
System.
Contact pin generally comprises guide pin section 2, riveting endpiece 3 and guide pin section 2 is arranged in and rivets the retaining section between endpiece 3
4, it specifically describes, the general endpiece 3 that rivets is equipped with lower edge, which is used to be cooperated with the department of assembly in connector shell 1,
For riveting circumferential limit when 5 bolt of connecting terminal of endpiece 3 and outer lead, contact pin generates rolling when preventing spiral from tightening
Dynamic, retaining section 4 is used to generate with the department of assembly in connector shell 1 and contact, and prevents contact pin axial direction position occur in plug
It moves.The above are the prior arts to rivet the lower edge of endpiece 3 since there are certain distances between riveting endpiece 3 and guide pin section 2
Being difficult to play the role of circumferential limit prevents rotation, be spirally connected tighten when, be also easy to generate the lower edge of riveting endpiece 3 certain turn round
The influence of square causes contact pin to there is the risk that rotates in a circumferential direction.And individually also difficulty ensures axial stability to retaining section 4, is plugging
Cheng Zhong, retaining section 4 are easy to produce micro- deformation, so that there are axial displacement risks.
In this case, as shown in Fig. 2, being equipped with taper connection section 6 between retaining section 4 and guide pin section 2, set in taper connection section 6
Have axially grooved 61, guide pin section 2 is equipped with the spill annular groove 21 of neighbouring taper connection section 6, be equipped in connector shell 1 for
The conical limit wall 11 that taper connection section 6 abuts against, conical limit wall 11 are equipped with wearing for protrusion and connect in axially grooved 61
Spacing barrier 12, interior be equipped in the mating channel 13 of connector shell 1 only shake circle 14, and only rolling circle 14 matches with spill annular groove 21.
It specifically describes, when carrying out contact pin assembly, the guide pin section 2 of contact pin is passed through to the mating channel of connector shell 1
13, by circumferential adjustment, so that spacing barrier 12 and axially grooved 61 matched, conical limit wall 11 and taper connection sections 6
The conical surface abut against, only shake that circle is 14 matched with spill annular groove 21, then carry out the spiral shell of connecting terminal 5 with riveting endpiece 3 again
Tightly, during screwing tight, due to the riveting lower edge of endpiece 3 and axially grooved 61 combine, maximization reduces connecting terminal 5 and is twisting
Damage during tight to contact pin, finally reassembles the assembly parts of other connector shells 1.
Due to the cooperation between axially grooved 61 and spacing barrier 12, contact pin opposing connector shell 1 can be effectively reduced
Relatively circumferentially displaced, the cooperation of taper connection section 6 and conical limit wall 11 and the joint of retaining section 4 realize the firm of axial direction, in addition,
It is designed due to only shaking circle 14 with the spill annular groove 21 in guide pin section 2, the required precision to mating channel 13 can be reduced, while only shaking
The deflection that circle 14 can limit guide pin section 2 is shaken.
Refinement description is carried out to retaining section 4, which is provided with several raised 41 be circumferentially arranged, 41 direction riveting endpiece of protrusion
3 end face forms retaining face.The retaining retainer ring 7 for matching with retaining face is equipped in connector shell 1, certainly, using straight
The abutting that the ring channel structures connect are carried out at retaining face is also feasible.
In preferred embodiment, retaining section 4 is equipped with circumferential equally distributed at least four protrusion 41, and protrusion 41 is directly to exist
The flange protrusion of flange is cut in retaining section 4.Preferably, the main body of flange protrusion is in rectangle.At least meet four protrusions 41,
It is just able to achieve relatively stable retaining effect, certain quantity also excessively should not be no more than ten as far as possible, because opening up protrusion 41
It is more, the structural strength of contact pin can be had an impact.
It is illustrated to circle 14 is only shaken, only shaking circle 14 includes quoit or silica gel ring, and quoit has abrasion resistance properties, is filled
Friction is small for timing, and silica gel ring has preferably elastic-restoring force, and it is stronger only to shake effect.It can select according to actual needs
The type of circle 14 is only shaken, in addition, needing to open up cutting opening on quoit when selecting quoit, cutting opening is used for
The deformation assembly of quoit assembly.
Finally, the free end of guide pin section 2 is equipped with arc angling, it is easy to mating with sleeve, has certain guiding
Effect is human oriented design.
By above description it can be found that the utility model is applied to the contact pin of photovoltaic connector, dexterously devise recessed
Shape annular groove and only rolling circle, can play the role of only shaking, and improve conductance stability.It is formed between taper connection section and conical limit wall
Axial limiting realizes axial stability with retaining section jointly.The axially grooved design with spacing barrier and existing riveting endpiece
The common circumferential stability for realizing contact pin.Whole design is ingenious, easy to implement, and stabilization is coupled between contact pin and connector shell can
It leans on.
The technical solution of the utility model is fully described above, it should be noted that the tool of the utility model
Body embodiment is simultaneously not limited by the description set out above, and those skilled in the art exist according to the Spirit Essence of the utility model
All technical solutions that structure, method or function etc. are formed using equivalents or equivalent transformation, all fall within this reality
Within novel protection scope.
