Summary of the invention
The problem that invention will solve
As stated, when the main circuit terminal 2 of the circuit brake (with reference to Fig. 5) that will be wired to above-mentioned such existing structure, as its work flow; Temporarily unscrew and unload screw thread and twist and to close the terminal screw 7 that remains on terminal board 5, then, with the terminal screw 7 fastening electric wires that are inserted into terminal board 1a; After this, terminal cover 4 is installed in terminal board 1a, therefore; Under the situation of the control panel that is equipped with many circuit brakes, this wiring operation needs more labour and time.
In addition, when the circular crimp type terminal to electric wire carries out distribution, need temporarily unload terminal screw; But as stated; The mounting position of circuit brake that is arranged in the dish is so that operating grip 3 is provided with towards the place ahead, therefore, uses when revolving tool and unloading terminal screw 7; There is generation operate miss easily, the problem that causes pad 6, terminal screw 7 to come off and drop in the dish, lose from terminal board 1a.
In addition; In order to reduce wiring operation number in man-hour; The structure of body shell that the terminal cover of open and close type is located at integratedly circuit brake is also known for people, still, and in order to adopt this mode; The shaping dies that needs the change body shell can not be applicable to the circuit brake goods that circulation launches on market now simply.
The present invention proposes in view of above-mentioned existing in prior technology problem; Its purpose is; A kind of arrangements of terminal of improved circuit-breaker is provided, and is object with above-mentioned circuit brake, existing body shell is not applied change; Utilize the terminal cover of the appurtenances of the terminal board that is installed in body shell dexterously, realize the improvement of wiring operation property.
The technological means that is used to deal with problems
In order to achieve the above object; According to the present invention; In the arrangements of terminal of circuit-breaker, will comprise terminal board, terminal screw, pad, the main circuit terminal of mains side, load-side is provided on the terminal board of the main circuit that is formed on the body shell two ends; As appurtenances, be provided with the terminal cover that is installed in above-mentioned terminal board and covers the main circuit terminal;
Wherein, at above-mentioned terminal cover, pad and the terminal screw with the main circuit terminal makes up in advance; Remain on assigned position temporarily, when carrying out distribution, the terminal cover is being installed under the state of terminal board; From the outside of this terminal cover terminal screw is tightened operation, the electric wire clamping is fastened between the terminal board and pad of main circuit terminal (technical scheme 1), particularly; With respect to the terminal cover, by interim terminal screw, the pad that keeps the main circuit terminal that be described below.
Promptly; The terminal cover is the lid bodies that is reverse U shape; The tab-like one-tenth pair of right and left of the rear portion lateral margin support foot sheet and the engaging protrusion of wall above that, and, be formed with the fastening patchhole that revolves tool of screw at upper wall with the mode of opening; Terminal screw is being inlayed under the state that inserts pad, pad is being pressed between the above-mentioned support foot sheet and interim keep (technical scheme 2).
Effect of the present invention.
According to the arrangements of terminal of above-mentioned formation, can realize following effect.That is, circuit-breaker is being arranged under the dish internal state, in the time will being wired to its main circuit terminal; The user will keep the terminal cover of terminal screw, pad to be installed in the terminal board of body shell in advance temporarily; Under this state, will revolve tool and insert the hole that is located in terminal cover upper wall, tighten terminal screw; Through so simple operation, can carry out the fastening and wiring of screw to the electric wire that inserts terminal board.Thus; Save the work of as existing goods, when distribution, unscrewing terminal screw, unloading from terminal board; Can reduce distribution number in man-hour; In addition, do not worry following the operation of unscrewing, unloading and the terminal screw that causes of terminal screw, the problem of losing that comes off of pad, can in the short time, carry out wiring operation efficiently.
And the body shell of circuit-breaker there is no need to change structure, and only need change slightly at the terminal cover of appurtenances just can be corresponding.

Embodiment
Below, with above-mentioned circuit brake the execution mode of the present invention of object according to Fig. 1-explanation embodiment illustrated in fig. 4.For in implementing illustration with Fig. 5, Fig. 6 corresponding components, be marked with same-sign, omit explanation.
The circuit brake of illustrated embodiment is identical with Fig. 5, prior art shown in Figure 6 example structure basically; But; When goods dispatched from the factory, terminal screw 7, pad 6 in that the terminal board 1a of body shell 1 does not install main circuit terminal 2 were described below; Pad 6, terminal screw 7 are delivered to the user with the goods binding to remain under the state as the terminal cover 4 of the appurtenances of circuit brake temporarily.
That is, the upper wall rear portion at the terminal cover 4 of the terminal board 1a that is installed in body shell 1 forms pair of right and left support foot sheet 4a and the engaging protrusion 4b identical with the existing goods of Fig. 6, from the lateral margin of upper wall towards the below outstanding formation.So, as shown in Figure 3 in the illustrated embodiment, terminal screw 7 being inlayed under the state that inserts pad 6, this pad 6 is pressed between the support foot sheet 4a, the upper wall that temporarily remains on terminal cover 4 is inboard.
For this reason, the inside dimensions between the pair of right and left support foot sheet 4a (Internal Dim) L is redefined for consistent with the width dimensions d of pad 6.The interim holding position of the fore-and-aft direction of pad 6 preestablishes as follows: at the gathering sill 1c (with reference to Fig. 5) that support foot sheet 4a is inserted the partition wall 1b of the terminal board 1a that is formed on body shell 1; Terminal cover 4 is installed under the state of terminal board 1a of body shell 1, remains on the screw (with reference to Fig. 2) relative to each other of axle front end and terminal board 5 of the terminal screw 7 of terminal cover 4 temporarily.
In addition, insert the operation that terminal cover 4 is carried out stubborn terminal screw 7 in order to revolve tool from the outside, at terminal cover 4 upper walls, like Fig. 1 (b), shown in Figure 4, as one man bore a hole in the interim holding position of revolving tool patchhole 4d and terminal screw 7.The aperture of revolving tool patchhole 4d is about 6mm.
In said structure; When to being arranged on circuit brake in the dish when carrying out distribution; As its work flow, the feasible in advance terminal cover 4 that temporarily maintains the appurtenances of pad 6, terminal screw 7 embeds the partition wall 1b installation (with reference to Fig. 2 (a) and (b)) of terminal board 1a from the place ahead of body shell 1.The electric wire front end that carries out distribution subsequently (wire rod or crimp type terminal) is inserted terminal board 1a through terminal cover 4; Under this state; What will revolve that tool is inserted into terminal cover 4 revolves tool patchhole 4d, twists in the screw that is combined in terminal board 5 while be pressed into terminal screw 7, carries out fastening operation.Thus, electric wire is held and is fastened between terminal board 5 and the pad 6.
Can know from this work flow; In the wiring operation that will be wired to the main circuit terminal, there is no need to carry out the work as in the prior art, terminal screw 7 being unscrewed, unloaded, can reduce distribution number in man-hour; In addition; In the screw operating process, do not worry that terminal screw 7, pad 6 come off from terminal board 1a, can in the short time, carry out wiring operation effectively.
Above with reference to description of drawings embodiments of the invention, but the present invention is not limited to the foregoing description.In technological thought scope of the present invention, can do all changes, they all belong to protection scope of the present invention.
