Further, the input terminal and output end are conducting wire, and the line section of conducting wire used is 1-15mm², the line section of conducting wire Face is bigger, and the maximum current that can be connected is bigger, can need to be adjusted according to practical debugging

Further, the line section of the conducting wire is preferably 2-8mm², the line section of conducting wire is bigger, and cost is higher, line section For 2-8mm²Not only it had been able to satisfy debugging demand, but also cost can be reduced, had been killed two birds with one stone.

Further, the output end is equipped with 1-20 altogether, can need to be adjusted according to practical debugging.

Further, the attachment device is copper bar, and used that input terminal can be made to connect with output end is more smooth.

Further, the storage area is fixed on the groove of fixation device surface or the inside groove of fixed device, by groove or Inside groove stores the conducting wire of output end in good orderly, and in debugging, Shi Nengrang commissioning staff is mounted directly, and is avoided that because of route More, storage disorderly, and causes to be shorted and malfunction, and influences debugging result.

Further, the groove or inside groove cross section are greater than the line section 1-2mm of conducting wire²。

Further, material used in the fixed device is plastics

Compared with prior art, the beneficial effect of technical solutions of the utility model is:

(1) the utility model is by fixed on the securing means by input terminal and output end, allow input terminal and output end by It places to orderliness, commissioning staff is directly shorted use in debugging, can effectively save debug time, reduces people needed for debugging Power, also avoid frequently relocating the maloperation that may cause.

(2) as the utility model proposes tool used in material it is cheap, structure is simple, and use is quick and convenient, energy Cost needed for debugging is reduced, is conducive to promote and apply, also improves debugging efficiency.

Specific embodiment

The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；

In order to better illustrate this embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent actual product Size；

To those skilled in the art, it is to be understood that certain known features and its explanation, which may be omitted, in attached drawing 's.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, be also possible to be indirectly connected with by intermediary, it can be with Say the connection inside two elements.For the ordinary skill in the art, it can understand that above-mentioned term exists with concrete condition The concrete meaning of the utility model.
