Abstract
A kind of contact system of blast switch.The contact system mainly solving existing blast switch is easily stopped by dust, causes loose contact, the problem of unstable properties.It is characterized in that: described first fixed contact, the second fixed contact surface are provided with Contact Tooth, described moving contact is also provided with the Contact Tooth corresponding with the first fixed contact, the second fixed contact.Its advantage is to not only increase contact area, and contact-making surface can be avoided to be covered by dust, and serviceability is more stable.
Description
Technical field
The utility model relates to a kind of blast switch, is specifically related to a kind of contact system of blast switch.
Background technology
Blast switch is a kind of detecting element, and being mainly used in needs to detect blast mechanically, and as pneumatic press, airoperated clipper, gas heater etc. use the electric equipment products of combustion gas class, it utilizes the pressure of gas to promote sensitive switch to realize.
Blast switch is generally used in small area analysis circuit, in use for some time, dynamic and static contact must have dust, but small area analysis is but not enough to puncture dust, connection circuit, thus causes blast switch to lose efficacy, unstable properties.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of contact system of blast switch, and the contact system solving existing blast switch is easily stopped by dust, causes loose contact, the problem of unstable properties.
The technical scheme that the utility model adopts: a kind of contact system of blast switch, comprise base, upper cover, movable contact spring, described movable contact spring is arranged in the cavity that base and upper cover form, described movable contact spring one end is provided with moving contact, described base is provided with the first binding post, the second binding post, and one end that described first binding post, the second binding post are arranged on chassis interior is respectively equipped with and is provided with the first fixed contact, the second fixed contact; Described moving contact is arranged between the first binding post, the second binding post; Described first fixed contact, the second fixed contact surface are provided with Contact Tooth, described moving contact are also provided with the Contact Tooth corresponding with the first fixed contact, the second fixed contact.
Described moving contact and the first fixed contact, the second fixed contact interlaced arrangement.
Described first binding post, the second binding post are in " L " character form structure.
Described first fixed contact welds with the first binding post, and described second fixed contact welds with the second binding post.
The beneficial effects of the utility model are: adopt above scheme, not only increase contact area, and contact-making surface can be avoided to be covered by dust, and serviceability is more stable.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the enlarged diagram of A in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in the figure, a kind of contact system of blast switch, comprises base 1, upper cover 2, movable contact spring 3, and described movable contact spring 3 is arranged in the cavity that base 1 and upper cover 2 form, and described movable contact spring 3 one end is provided with moving contact 4,
Described base 1 is provided with the first binding post 7, second binding post 8, and one end that described first binding post 7, second binding post 8 is arranged on base 1 inside is respectively equipped with and is provided with the first fixed contact 5, second fixed contact 6;
Described moving contact 4 is arranged between the first binding post 7, second binding post 8, and moving contact 4 and the first fixed contact 5, second fixed contact 6 interlaced arrangement;
Described first fixed contact 5, second fixed contact 6 surface is provided with Contact Tooth 9, described moving contact 4 is also provided with the Contact Tooth corresponding with the first fixed contact 5, second fixed contact 6.
Moving contact and the first fixed contact, the second fixed contact are contacted by Contact Tooth and connect, and not only increase contact area, and contact-making surface can be avoided to be covered by dust, serviceability is more stable.
Wherein, described first binding post 7, second binding post 8 is in " L " character form structure.
Described first fixed contact 5 welds with the first binding post 7, and described second fixed contact 6 welds with the second binding post 8, and the connected mode of welding is produced easier for installation.
