Abstract
The invention discloses a movable contact bridge member which comprises a push rod (21) and a contact bridge (22). The push rod (21) is made of metal materials, a metal casing (24) and an insulating casing (25) are sequentially arranged between the push rod (21) and the contact bridge (22), the insulating casing (25) is contacted with the contact bridge (22), the longitudinal face of the metal casing (24) is contacted with the push rod (21) by an interval, and the transverse face of the metal casing (24) and the contact bridge (22) are separated by a mica spacer (26). The push rod made of the metal materials and the contact bridge are insulated and separated by the insulating casing and the mica spacer, and the invention has the characteristics of high temperature resistance, impact resistance, wear resistance, good toughness and insulativity and obviously prolonged service life and is especially suitable for electrical products of throw over relays (contactors), switches, and the like.
Description
Technical field
The present invention relates to the movable contact bridge member that a kind of electric equipment products are used.
Background technology
At present, movable contact bridge member is applied to electric equipment products, and it is made up of push rod, contact bridge etc., and push rod is the middle part that common insulating material is located at contact bridge (for metal material); When external force acted on push rod, the both ends of contact bridge contacted and energising work with another kind of contact bridge.Because the electric equipment products working temperature is high, also corresponding higher to material requirements, push rod is common insulating material as critical piece, temperature distortion easily, and impact resistance is poor, has influenced the useful life of electric equipment products.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and a kind of high temperature resistant, shock-resistant, movable contact bridge member that insulating properties is good is provided.
The object of the invention is realized through following technical scheme: a kind of movable contact bridge member; Comprise push rod, contact bridge; Said push rod is a metal material, and metal sleeve and insulating sleeve are housed between this push rod and the contact bridge successively, and said insulating sleeve contacts with contact bridge; The longitudinal surface of said metal sleeve contacts with push rod at interval, is separated by by mica spacer between the athwartship plane of metal sleeve and the contact bridge.
After adopting the present invention; Between the push rod of metal material and the contact bridge by insulating sleeve and the mica spacer partition that insulate; Have high temperature resistant, shock-resistant, anti abrasive characteristics; And toughness, insulating properties are good, have obviously prolonged useful life, are specially adapted to electric equipment products such as throw over relay (contactor), switch.
Description of drawings
Below in conjunction with accompanying drawing and execution mode the present invention is made further detailed description.
Fig. 1 is the structural representation of activity contact bridge member of the present invention.
Embodiment
Can know with reference to Fig. 1; Activity contact bridge member of the present invention; Comprise push rod 21, contact bridge 22 (being metal material, contact bridge in the middle of also can claiming), said push rod 21 is metal material (can be copper material); Metal sleeve 24 (can be copper material) and insulating sleeve 25 are housed between this push rod 21 and the contact bridge 22 successively; Said insulating sleeve 25 contacts with contact bridge 22, and the longitudinal surface of said metal sleeve 24 contacts (should leave very small space between the longitudinal surface of metal sleeve and the push rod) at interval with push rod 21, is separated by by mica spacer 26 (insulation) between the athwartship plane of metal sleeve 24 and the contact bridge 22.
Wherein, push rod 21 is located at the middle part of contact bridge 22; Metallic gasket 27 (can be iron material) also can be housed, to increase tightness and firmness between the athwartship plane of said metal sleeve 24 and the mica spacer 26; Being peripherally equipped with overtravel reed 28 and withstanding on the metal sleeve 24 of said push rod 21, and spring base 23 is housed, puts in place so that push rod can in time be worked at the afterbody of push rod 21; The head of said push rod 21 is an evagination cone-shaped 29, to match with indent cone tank that its contacted iron core has, to increase the stability and the degree of balance of pushrod movement; Said insulating sleeve 25 for mica, gather tetrafluoro, glass fiber or ceramic insulation tubing, its lasting 1-2 minute high temperature resistant reaches 300-450 ℃, moment is high temperature resistant to reach 600-700 ℃, wherein with ceramic insulation tubing best results.
When external force acts on push rod (metal material), impel the both ends (can be flat contact or contact chip) of contact bridge to contact and energising work with another kind of contact bridge (can be contact bridge, following contact bridge or curve contact bridge).
