Abstract
Disclosed in the utility model is a moving contact of a trigger switch. The cross section of the moving contact is in an I shape. The moving contact comprises an I-shaped connecting installing portion, an upper contact layer and a lower contact layer, wherein the upper contact layer and the lower contact layer are arranged at an upper end surface and a lower end surface of the connecting installing portion. The upper contact layer and the lower contact layer are contact layers made of silver materials; and the connecting installing portion is one made of copper materials or aluminium materials. According to the moving contact, a three-layer composite structure is employed; and reliable contact between the moving contact and a static contact can be completed to form double loops in practice and the material cost can be lowered.
Description
Technical field
The utility model relates to a kind of moving contact, refers to a kind of moving contact of trigger switch especially.
Background technology
The cross section of used moving contact is I-shaped in the existing trigger switch, and this I-shaped moving contact is installed on the movable contact spring by recess, drives the upper and lower movement of moving contact by movable contact spring, thereby realizes connecting with last or following fixed contact.Right present moving contact mostly adopts the fine silver material to satisfy the two circuit requirement of formation, and cost is higher.Can not adapt to market demands.
The utility model content
Technical problem to be solved in the utility model is: a kind of moving contact of trigger switch is provided, and this moving contact adopts three-layer composite structure, can either satisfy in the practical application reliably to contact the formation double loop with fixed contact, can reduce material cost again.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of moving contact of trigger switch, the cross section of this moving contact is I-shaped, the last contact layer and the following contact layer that comprise I-shaped connection portion and be positioned at the upper and lower end face of connection portion, this upper and lower contact layer is the contact layer of silver-colored material, the connection portion that this connection portion is copper material or aluminium.
As a kind of preferred scheme, described upward contact layer is identical with the thickness of following contact layer.
As a kind of preferred scheme, the described thickness of going up contact layer and following contact layer is 0.3mm.
As a kind of preferred scheme, the last contact-making surface of described upward contact layer, the following contact-making surface of following contact layer are arcwall face.
After having adopted technique scheme, effect of the present utility model is: because this moving contact is three-layer composite structure, and upper and lower contact layer is silver-colored material, the connection portion at middle part then is copper, like this, the upper and lower contact layer of this moving contact can effectively and reliably contact with fixed contact, and copper connection portion has also reduced the cost of moving contact.
Because the following contact-making surface of the last contact-making surface of last contact layer, following contact layer is arcwall face, it contacts more reliable with fixed contact again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure cutaway view before not the installing of the utility model embodiment;
Fig. 2 is the scheme of installation of the utility model embodiment;
In the accompanying drawing: 1. moving contact; 2. go up fixed contact; 3. movable contact spring; 4. housing group; 5. push rod; 6. driver blade; 7. terminal C; 8. descend fixed contact.
Embodiment
Below by specific embodiment the utility model is described in further detail.
As shown in Figure 1, 2, a kind of moving contact 1 of trigger switch, the cross section of this moving contact 1 is I-shaped, the last contact layer and the following contact layer that comprise I-shaped connection portion and be positioned at the upper and lower end face of connection portion, moving contact 1 when having shown not moulding among Fig. 1, namely utilize the mode of the blank utilization extruding of T shape can be with moving contact 1 lower end crimp, thereby be molded into moving contact 1 I-shaped and be installed on the movable contact spring 3.
Is this upper and lower contact layer the contact layer of silver-colored material, and thickness is identical, is? mm, the last contact-making surface of described upward contact layer, the following contact-making surface of following contact layer are arcwall face.The connection portion that this connection portion is copper material or aluminium like this, has just saved the cost of installation portion, and the cost of whole moving contact 1 reduces, but upper and lower contact-making surface is silver-colored material, has guaranteed that again the loop contact is reliable.
The operation principle of present embodiment is: at first, this trigger switch comprises housing group 4, and three terminals are installed on the housing group 4, i.e. A, B, terminal C7, A terminal and B terminal are that fixed contact 2 and following fixed contact 8 are installed in the inside of housing group 4, and the contact-making surface of upper and lower fixed contact 8 also is silver-colored material.Movable contact spring 3 one ends are connected with moving contact 1, and the other end is installed on the terminal C7, and moving contact 1 is connected with push rod 5 by connecting rod, and the lower end of push rod 5 is provided with driver blade 6 and is used for push rod 5 is resetted.During this switch initial condition, moving contact 1 and last fixed contact 2 closures, terminal A and terminal C7 connect, and moving contact 1 disconnects with following fixed contact 8, and terminal B and terminal C7 are in off-state; When pressing the button, button compressing driver blade 6, connecting rod drives movable contact spring 3 and moves downward, and makes moving contact 1 and last fixed contact 2 disconnect, and terminal A and terminal C7 are in off-state, moving contact 1 and following fixed contact 8 closures, terminal B and terminal C7 connect; Realize the two circuit switching of switch.
Claims (4)
1. the moving contact of a trigger switch, the cross section of this moving contact is I-shaped, it is characterized in that: the last contact layer and the following contact layer that comprise I-shaped connection portion and be positioned at the upper and lower end face of connection portion, this upper and lower contact layer is the contact layer of silver-colored material, the connection portion that this connection portion is copper material or aluminium.
2. the moving contact of a kind of trigger switch as claimed in claim 1 is characterized in that: described to go up contact layer identical with the thickness of following contact layer.
