Description
Technical field
The utility model belongs to breaker technical field, is specifically related to the auxiliary row of connection of a kind of circuit breaker fixed structure
Background technology
Chinese utility model patent ZL200720044106.7 has disclosed the jockey of circuit breaker turnover line, has specifically instructed: when mounted, earlier line bank and breaker body pedestal are fixed, auxiliary connection row then is installed; Also instructed when changing auxiliary connection row, need not to open the breaker body lid, also need not the fixed connecting piece between removal line bank and the breaker body pedestal, therefore had and install and change strong point easily.
The assembling of
above-mentioned patent is the round boss of auxiliary connection row bottom to be pushed in the cavity that (entering) breaker body base bottom offers auxiliary connection row.That is to say; When pushing auxiliary connection when row, through to the morphotropism extruding of the round boss of side channel top just so that auxiliary connection row pushes puts in place, follow; The round boss of side channel top restores to the original state, and discharges deformation force simultaneously auxiliary connection row's bottom round boss is pushed in the cavity.It is thus clear that this assembling form is very harsh to the accurate requirement of boss flange height, yet in the process that constitutes the boss flange, burr often is difficult to control, in order to guarantee the quality of boss flange, avoid burr to produce, thereby make efficiency is lower.In addition, when changing auxiliary connection row, be to rely on the distortion of boss to realize during owing to assembling, therefore very easily undermine the boss on the pedestal.
To above-mentioned shortcoming, the applicant has made good try, has found the way of dealing with problems, and the technical scheme that will introduce below produces under this background
Summary of the invention
The task of
the utility model is to provide a kind of auxiliary row's fixed structure that is connected of circuit breaker of installing and helping preventing the boss damage on the breaker body pedestal that helps to simplify.
The task of
the utility model is accomplished like this; The auxiliary row's fixed structure that connects of a kind of circuit breaker; Comprise pedestal, be installed on the auxiliary connection row on the pedestal and be installed on the terminal fixed block on the pedestal equally; On each utmost point sidewall of said pedestal and in the aspectant position of sidewall, respectively have a boss, and with each utmost point sidewall of the corresponding opposite side of boss on respectively constitute a groove in aspectant position equally, have a pair of step that is mutually symmetrical on the said auxiliary connection row; Has a pair of external part on the described terminal fixed block; This matches with said step through said groove to external part, after described auxiliary connection row is fixing, contacts with boss with external part respectively.
described external part of the utility model is suitable with described groove, and wherein: external part is plates, and groove is the sheet cavity that is used to compensate external part, and described step is a cuboid.
Also have projection on
described external part of the utility model, described groove also has cavity, and projection is charged in the cavity.
The technical scheme that
the utility model provides has can be simplified installation and can prevent the strong point damaged as the boss on the pedestal of breaker body again.
Description of drawings
Fig. 1 is the utility model overall structure figure.
Fig. 2 is the auxiliary connection row's of the utility model a structure chart.
Embodiment
Fig. 1 and Fig. 2 are asked for an interview in
; The auxiliary row's fixed structure that connects of a kind of circuit breaker comprises pedestal 1 (being the breaker body pedestal, as follows); Auxiliary connection row 2 and terminal fixed block 3, auxiliary connection row 2 all be fixed on the pedestal 1 with terminal fixed block 3.Respectively be provided with a boss 11 on each utmost point sidewall of pedestal 1 and in the position that faces each other; On each utmost point sidewall and be provided with groove 12 with boss 11 corresponding opposite sides; Auxiliary connection row 2 is provided with the step 21 (Fig. 2 is detailed to be shown) of two symmetries; Terminal fixed block 3 is provided with a pair of external part 31, and this cooperates with step 21 through (warp) groove 12 external part 31.
Contact system and the operating mechanism and the arc control device of circuit breaker are installed on
pedestal 1; Contact system one end is electrically connected with being connected row 4, after connection row 4 is electrically connected through binding post and turnover line, and can be with the contact system and the main circuit conducting of circuit breaker; Thereby the operate as normal that circuit breaker can protective circuit; When abnormal current occurring, can in time cut off electric current, prevent that load appliance receives the influence of abnormal current.For binding post is fixed, need the fixing auxiliary row of connection 2 on pedestal 1.Therefore on each utmost point sidewall of pedestal 1 and at aspectant position, respectively establish a boss 11, boss 11 is oblique contract shape.The inclined-plane of boss 11 heads is positioned at the top, and boss 11 end planes are arranged 2 contacts with auxiliary the connection, play a supporting role.Bearing of trend at boss 11 on the pedestal 1 is provided with groove 12, the shape of groove 12 should with the form fit of the external part 31 of terminal fixed block 3, thereby after the external part 31 of terminal fixed block 3 is through groove 12, can be connected row 2 and fix with will assisting after boss 11 cooperates.
auxiliary connection on the row 2 has a screwed hole 22, and screwed hole 22 is used for fixing binding post.Aforesaid step 21 is used for the auxiliary row's of connection 2 fixing own.
aforesaid external part 31 is body in the form of sheets, and its shape should be able to guarantee himself to have certain intensity.
When install
; To assist connection row 2 to be pushed into assigned address earlier; Push terminal fixed block 3 this moment, terminal fixed block 3 carries external part 31 and connects row 2 along groove 12 near assisting, and final the insertion assisted in the step 21 that connects row 2; Simultaneously, auxiliary connection row 2 receives boss 11 end planes to stop and can't make a concession.Because external part 31 inserts groove 12, assist connection row 2 outwards to move simultaneously, auxiliary connection is arranged 2 and is fixed in assigned address.
The auxiliary row of connection 2 of this kind is adopted in
, need not utilize the distortion of boss 11 to accomplish installation, so boss 11 can not damage because of being squeezed.Simultaneously, in the auxiliary connection row's 2 of dismounting the process, only needing to move terminal fixed block 3 can realize, simple to operate, easy for installation.
preferably are provided with a pair of projection 311 on aforesaid extension 31, corresponding, on groove 12, are provided with a pair of cavity 121, and cavity 121 cooperates with projection 311, thus the fixing terminal fixed block 3 of insertion.Because extension 31 also cooperates with step 21; Therefore; Can the spacing distance of a pair of step 21 be set at the distance of being a bit larger tham between a pair of external part 31, thereby after external part 31 inserts steps 21, each deflection laterally of a pair of external part 31; And increase the degree of depth that projection 311 is inserted cavitys 121, make fixed effect and then the improvement of terminal fixed block 3 on pedestal 1.
In sum, the technical scheme that the utility model provides both can help convenient the installation, helped avoiding when mounted causing the boss 11 that undermines on the pedestal 1 again
