Abstract
The present invention relates to a connection accessory for electrical apparatus, especially a circuit breaker, a contactor, a switch or the like. This accessory (11) includes a housing (20) in which are mounted a connection region (16), at least one main connecting case (21) which interacts with a clamping screw (22) in order to define, with this case, a main connection terminal (23) and at least one auxiliary connection terminal (24) which interacts with a clamping screw (25) in order to define, with this case, an auxiliary connection terminal (26). This accessory is designed to allow effective and reliable connection of at least one power cable and of at least one auxiliary conductor.
Description
The present invention relates to the connection fittings of a kind of electrical switchgear, particularly circuit-breaker, contactor, switch etc., this electrical switchgear comprises at least one input and an output, and each terminal all is equipped with one and connects cavity and a holding screw.
Size that the connection cavity of electrical switchgear is limited usually and the shape of determining meticulously.In the time must connecting the big power cable of diameter or must connect several cables in a cavity, it is big inadequately that the size of this cavity just seems.
In addition, in some electric component, power cable that diameter is bigger and auxiliary conductor must be connected in the cavity, for example are connected with transducer or any equipment that other is fit to.In this case, connection may be broken down, because auxiliary conductor is clipped between the diameter bigger cable and re-entrant part more or less, makes auxiliary conductor fixing bad, poor location.
The connection fittings that the objective of the invention is the various needs by being met electric component overcome above-mentioned shortcoming.
The invention provides a kind of connection fittings that are used for electrical switchgear, described switching device comprises at least one input and an output, each terminal all is equipped with one first and connects cavity and one first holding screw, this accessory is characterised in that: the shell of accessory comprises a main link and an auxiliary link, they contact fillet and are electrically connected with one, the contact fillet inserts the described connection cavity of described switching device, and fix by corresponding first holding screw, main link comprises one second main cavity and one second holding screw of connecting, described second cavity with contact fillet and be electrically connected, auxiliary link comprises one the 3rd auxiliary cavity and one the 3rd holding screw of connecting, described the 3rd cavity with contact the fillet electrical connection.
To the description of the most preferred embodiment that provides as non-limiting example and in conjunction with the accompanying drawings the present invention will be more readily understood with reference to following, in the accompanying drawing:
Fig. 1 is the part stereogram that is equipped with according to the circuit-breaker shell of two connection fittings of the present invention, and two connection fittings are arranged in each side of circuit-breaker;
Fig. 2 is the part positive view that is installed in the connection fittings of circuit-breaker one side according to of the present invention; And
Fig. 3 is accessory is seen in expression from the below view that is similar to Fig. 2.
With reference to accompanying drawing, Fig. 1 particularly, circuit-breaker 10 (its shell has only drawn) is equipped with two connection fittings 11 and 12, and they are fixed on each side of circuit-breaker.With regard to its principle, these two parts are similarly, but are different from their structure, and their structure is suitable for being installed in respectively the right side and the left side of circuit-breaker, and the shape difference of these both sides particularly connects the position difference of cavity accordingly.
Circuit-breaker comprises two recesses 13, and design is used for holding and connects cavity 14 (see figure 2)s, connects cavity 14 and forms with holding screw 15, input and output link together.Usually cavity 14 designs are used for holding power cable and/or auxiliary conductor.In described embodiment, they with contact fillet 16 and link to each other, contact fillet 16 is a kind of parts that constitute in the parts of connection fittings 11 or 12.
Be described in more detail below connection fittings 11, should understand, all parts in the connection fittings 11 can both find in connection fittings 12, and have identical functions.This accessory comprises the shell of being made by molded synthetic material 20, several recesses are wherein arranged, be used to hold contact fillet 16, at least one cooperates a master to determine a main link 23 to be connected cavity 21 with a holding screw 22, and at least one cooperates to determine an auxiliary cavity 24 that is connected of an auxiliary link 26 with a holding screw 25.Contact fillet 16 comprises a joint in the cavity 14 that is contained in circuit-breaker, first extension 17 of extending in main cavity 21 and second extension 18 of extending in auxiliary cavity 24.The contact fillet preferably cuts down from the good material of electric conductivity, particularly copper or copper alloy, and shape is suitable.
Concerning some use occasion, connection fittings can comprise several main links and several auxiliary link.In this example, connection fittings include only a main link and an auxiliary link.The power cable (not shown) inserts main cavity by the opening 27 that is positioned on the shell 20.The auxiliary conductor (not shown) inserts auxiliary cavity by passage 28 and the opening 29 at the rear portion, the end of this passage that also is positioned on the shell 20.Terminal is complementary with the cable dimension that is connected.
This embodiment has solved the problem on the end of inputing or outputing that power cable and auxiliary conductor is fixed to simultaneously circuit-breaker or other electrical switchgear.
