Abstract
The utility model provides a connecting device between a middling pressure breaker contact arm and a solid-sealed polar pole, comprising a solid main body (10) with a pole end and a wall contact end respectively provided with a projecting part (101,102), the projecting parts (101,102) being both provided with threads. The intermediate part of the solid main body (10) is provided with a shoulder part (103) which has two side surfaces (1031) divided flat. The projecting parts (101,102) are respectively sleeved with at least one taper pad (11). The connecting device raises conductive performance and reduces tolerance requirements of a whole dimension chain.
Description
Technical field
The utility model belongs to the medium voltage electricity product technical field, relates in particular in a kind of medium voltage breaker technical field the jockey of contact arm and pole.
Background technology
Following two kinds of modes that connect two parts are arranged usually: 1) therein one open the hole above the part, open thread at the another one part, use bolt that two parts are locked then.2) all open the hole above the part for two, right hand uses bolt and nut that two parts are locked.
Be illustrated in figure 1 as in above-mentioned first kind of existing circuit breaker design, as shown in the figure, have a through hole in the whole contact arm, the screw thread hole the inside above the pole on the right of bolt is locked in from left to right.
Aforesaid prior art scheme have following subject matter: because the centre has through hole, the circuit breaker contact arm contact little with pole, and under the situation of use copper product, conductivity can meet the demands, and still changes after the aluminum electric conductivity variation into.No matter use what material, its electric conductivity is not optimum.
The utility model content
The purpose of this utility model is to provide the jockey of a kind of medium voltage breaker contact arm and pole, and it comprises solid body, and the pole end of solid body and tactile wall end have a protuberance respectively, and screw thread is all arranged on the protuberance.
According to most preferred embodiment of the present utility model, a shoulder is arranged in the middle of the solid body, and shoulder has and is cut two flat sides.
According to most preferred embodiment of the present utility model, the protuberance of pole end and tactile wall end respectively is with at least one pad.
According to most preferred embodiment of the present utility model, described pad is the taper pad, and is preferred, touches on the wall end protuberance and is with two pads.
The jockey of medium voltage breaker contact arm of the present utility model and pole owing to removed through hole, makes the circuit breaker contact arm contact increase with pole, no matter uses copper product or aluminum, and its electric conductivity can both meet the demands.Satisfy the requirement of electric conductivity under the aluminum, can significantly reduce cost.Under the situation of using copper product, conductivity improves, and also can improve the performance of circuit breaker.
Description of drawings
Fig. 1 is the jockey structural representation of existing medium voltage breaker contact arm and pole;
Fig. 2 A-2B is most preferred embodiment structural representation of jockey of medium voltage breaker contact arm of the present utility model and pole; Wherein, Fig. 2 A is the profile after connecting, and Fig. 2 B is the stereogram of jockey;
Fig. 3 is the another most preferred embodiment structural representation of the jockey of medium voltage breaker contact arm of the present utility model and pole.
Embodiment
Below with reference to accompanying drawing, the specific descriptions of optional execution mode of the present utility model have been provided.
Fig. 2 A-2B is most preferred embodiment structural representation of jockey of medium voltage breaker contact arm of the present utility model and pole; Wherein, Fig. 2 A is the profile after connecting, and Fig. 2 B is the stereogram of jockey, and it comprises solid body 10, and the pole end of solid body 10 and tactile wall end have a protuberance 101,102 respectively, and screw thread is all arranged on the protuberance 101,102.
According to most preferred embodiment of the present utility model, in the middle of the solid body 10 shoulder 103 is arranged, and shoulder 103 has and is cut two flat sides 1031.Preferably, this 1031(another one side, two sides is not shown) be parallel tangent plane, apply moment when being used for this jockey is installed.
According to most preferred embodiment of the present utility model, the protuberance 101,102 of pole end and tactile wall end respectively is with at least one pad 11, and for example the taper pad is preferred, touches on the wall end protuberance 101 and is with two pads 11.
Shown in Fig. 2 A, between double end and pole, use a taper pad, yet then having two pads between contact arm and stud installs back-to-back, this scheme also needs to satisfy gap needs between contact arm and the stud than the thickness that two each and every one pads kill thick (otherwise following problem can occur: contact arm does not contact with the outlet terminal of pole), but the original height than two each and every one pads little (not so pad is compressed with regard to not having fully, and then does not have the effect of loosening).But the space that 2mm is just arranged of two pads absorbs mismachining tolerance.
Fig. 3 is the another most preferred embodiment structural representation of the jockey of medium voltage breaker contact arm of the present utility model and pole.Respectively put a taper pad in the stud both sides, be locked in above the pole with stud earlier, at this time the pad between them will be driven plain.Between stud and contact arm, just have another taper pad: as shown below, gap between contact arm and the stud need be thicker than the thickness that a pad kills, otherwise following problem can occur: contact arm does not contact with the outlet terminal of pole, but the original height than a pad is little, not so pad is compressed with regard to not having fully, and then does not have the effect of loosening; The original length of pad ratio kills only big 1mm of length then, thus this scheme to the hole depth of whole dimension chain such as contact arm and the shoulder height of stud, tolerance than higher.
The jockey of medium voltage breaker contact arm of the present utility model and pole owing to removed through hole, makes the circuit breaker contact arm contact increase with pole, no matter uses copper product or aluminum, and its electric conductivity all is improved.In addition, use the design of two taper pads, make the tolerance of whole dimension chain reduce.
Although disclose preferred embodiment of the present utility model and accompanying drawing for the purpose of illustration, the person skilled in the art in the spirit and scope that do not break away from the utility model and appended claim, can do various replacements, variation and retouching.Therefore, the utility model should not be limited to preferred embodiment and the disclosed content of accompanying drawing, and protection range of the present utility model is as the criterion with the scope that appending claims was defined.
