Abstract
The utility model relates to a kind of thermal overload relay, and it comprises shell, upper cover, main contact, main contact connecting rod, normally closed auxiliary contact; The surface of upper cover is provided with main contact connecting rod sleeve pipe, and main contact connecting rod sleeve pipe is communicated with shell, and one end of main contact connecting rod connects main contact, and the other end is stretched out by main contact connecting rod sleeve pipe; Wherein, described relay also comprises sleeve pipe, connection assist, described sleeve pipe is communicated with shell, and sleeve pipe is positioned at by main contact connecting rod sleeve pipe, and connection assist comprises fixed part that one end is connected with normally closed auxiliary contact and reaches the extension outside relay by sleeve pipe; The utility model has feature easily of making contact.
Description
Technical field
The utility model relates to a kind of thermal overload relay.
Background technology
When in existing thermal overload relay, electric equipment products traditional with other are connected, main contact connecting rod in thermal overload relay inserts in electric equipment products by usual employing, then the auxiliary contact in overtemperature relay is connected by the mode of making contact with the auxiliary contact in electrical equipment, because the distance between thermal overload relay and traditional electric equipment products is usually comparatively tight, space is less, adopts the mode of making contact to connect more inconvenient and trouble.
Utility model content
Problem to be solved in the utility model is to provide a kind of thermal overload relay.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of thermal overload relay, it comprises shell, upper cover, main contact, main contact connecting rod, normally closed auxiliary contact; The surface of upper cover is provided with main contact connecting rod sleeve pipe, and main contact connecting rod sleeve pipe is communicated with shell, and one end of main contact connecting rod connects main contact, and the other end is stretched out by main contact connecting rod sleeve pipe; Wherein, described relay also comprises sleeve pipe, connection assist, described sleeve pipe is communicated with shell, and sleeve pipe is positioned at by main contact connecting rod sleeve pipe, and connection assist comprises fixed part that one end is connected with normally closed auxiliary contact and reaches the extension outside relay by sleeve pipe.
In usual traditional electrical equipment, auxiliary contact is just arranged on by main contact, because auxiliary contact is connected with connector, inserted in the auxiliary contact of traditional electrical equipment fixing by the external part of connector, thus reach the effect connecting relay auxiliary contact and traditional electrical equipment auxiliary contact, tradition adopts the mode of making contact to connect to couple together because operating space is little and comparatively bothers, and adopts now this structure then to avoid trouble of making contact.
Wherein, also connecting portion is provided with between described fixed part and extension.
Wherein, the shape of described connecting portion is U-shaped.
Wherein, between described fixed part and connecting portion, angle is 90 °, and the angle of extension and connecting portion is 90 °.
Wherein, described fixed part is fixing in crimping with normally closed auxiliary contact.
Wherein, the cross sectional shape of described extension is rectangular.This structure is adopted to crimp with the auxiliary contact of traditional electrical equipment more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model thermal overload relay;
Fig. 2 is the structural representation of thermal overload relay after removal shell;
Fig. 3 is the structural representation that thermal overload relay is connected with traditional electrical equipment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1, 2, thermal overload relay of the present utility model, it comprises shell 11, upper cover 12, shell 11 and upper cover 12 coordinate rear inside to form the cavity holding thermal overload relay assembly, and thermal overload relay assembly comprises Bimetallic thermal element, main contact, normally closed auxiliary contact, the de-mouth mechanism of overload etc.; Main contact is connected with main contact connecting rod 13, upper cover 12 is communicated with main contact connecting rod sleeve pipe 14 and sleeve pipe 15, main contact connecting rod sleeve pipe 14 and sleeve pipe 15 are disposed side by side on the surface of upper cover 12, and one end of main contact connecting rod 13 is stretched out for being connected with other electrical equipment from main contact joint sleeve 14; Connection assist adopts electric conducting material, connection assist comprises fixed part 16, connecting portion 17, extension 18, the cross sectional shape of extension 18 is rectangular, fixed part 16 is fixing by normally closed auxiliary contact crimping, fixed part 16 is connected with extension 18 by connecting portion 17, and the shape of connecting portion 17 is U-shaped, and between fixed part 16 and connecting portion 17, angle is 90 °, extension 18 is 90 ° with the angle of connecting portion 17, and a part for extension 18 is stretched out for being connected with other electrical equipment by sleeve pipe 15.
Above-described embodiment of the present utility model is only preferred embodiment, and what those skilled in the art did under the guiding of technique scheme does not anyly have substantial improvement all to fall within the scope of protection of the present invention, and forms infringement.
