Abstract
The invention discloses a switch contact for an elevator door lock, comprising a contact body which is provided with a conductive part, wherein the conductive part is formed by a copper material layer which is connected to the contact body and a silver material layer which is connected to a contact surface that is in contact with an electric switch contact of the door lock on the copper material layer. One end face of the contact body is provided with a step structure; the copper material layer is connected to two planes on the step structure and a vertical surface between the two planes; and the silver material layer is only connected to the two planes. A copper and silver composite material is used on a contact surface (a surface in contact with an electric switch of the door lock) in the conductive part of the contact and only copper material is used on a noncontact surface; therefore, the contact reliability is not reduced but the cost is obviously reduced. Being skillfully designed, the switch contact for the elevator door lock has very high economic value and industrial value and is suitable for industrial application and popularization.
Description
Technical field
The present invention relates to a kind of elevator door lock assembly, relate in particular to a kind of door lock of elevator switch contact.
Background technology
Elevator must be after definite Room door and gate shut fully, and the just operation that can once go on foot is to guarantee safety, and closing the door to have duplicate protection, mechanical protection and electric protection.Electric protection be with gate signal as a contact signal, the door switch contact contacts with the door lock electric switch has just formed contact signal.When door shut, contact signal was normally closed point, and this moment, the door switch contact was pressed on the contact of door lock electric switch.Door is when opening or not shutting, and contact signal be normal the battle, and door switch contact and door lock electric switch are without any contacting the formation open contact.When normal the battle, elevator does not allow any action.
The elevator door lock assembly is four big safety components of elevator, require reliably to contact more than 1,000,000 times, present door lock of elevator is the copper silver composite material with the employing of switch contact current-carrying part, all used this material at noncontact face and contact surface, its contact surface is meant the plane that is contacted with door lock electric switch contact in the door switch contact.
Specifically as shown in Figure 1, door lock of elevator of the prior art comprises the contact body 2 with conductive part 1 with switch contact, described conductive part is by the copper material bed of material 3 that is connected on the described contact body, and the complete silver material layer 5 that is connected on the described copper material bed of material 3 constitutes, the defective of this structure is that cost is higher.
Summary of the invention
In view of this, technical matters to be solved by this invention is: lower-cost door lock of elevator switch contact when providing a kind of energy to guarantee reliable the contact.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
A kind of door lock of elevator switch contact, wherein, comprise the contact body with conductive part, described conductive part is by the copper material bed of material that is connected on the described contact body, and the silver material layer that is connected on the contact surface that contacts for door lock electric switch contact on the described copper material bed of material constitutes.
As preferably, an end face of described contact body has hierarchic structure, and the described copper material bed of material is connected in two planes on the described hierarchic structure and is connected on the vertical face between described two planes, and described silver material layer only is connected on described two planes.
As shown from the above technical solution, the invention has the beneficial effects as follows:
Compared to existing technology, the present invention is by using the copper silver composite material with the contact surface in the contact conductive part (plane that is contacted with the door lock electric switch), noncontact face only uses copper product, make the reliability of contact not reduce, but cost has significant reduction, its design is ingenious, has very high economic value and industrial value, is suitable for technical application and promotes.
Description of drawings
Fig. 1 is the perspective view of door lock of elevator of the prior art with switch contact.
Fig. 2 is the perspective view of door lock of elevator of the present invention with switch contact.
Fig. 3 is the construction profile scheme drawing of door lock of elevator of the present invention with switch contact.
Fig. 4 is the structural representation of door lock electric switch, has wherein illustrated the structure of door lock electric switch contact.
The specific embodiment
In order to make those skilled in the art can further understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing.
See also Fig. 2 to shown in Figure 4, the invention provides a kind of door lock of elevator switch contact, wherein, comprise contact body 2 with conductive part 1, described conductive part is by the copper material bed of material 3 that is connected on the described contact body, and the silver material layer 5 that is connected on the contact surface that contacts for door lock electric switch contact 4 on the described copper material bed of material 3 constitutes.An end face of described contact body has hierarchic structure, the described copper material bed of material 3 is connected in two planes (contact surface) on the described hierarchic structure and is connected on the vertical face between described two planes, and described silver material layer only is connected on described two planes (contact surface).
But the above only is a preferable possible embodiments of the present invention, is not in order to limiting to claim of the present invention, thus the equivalent structure that all utilizations specification sheets of the present invention and accompanying drawing content are done change, all in like manner within the scope of the present invention.
Claims (2)
1. door lock of elevator switch contact, it is characterized in that, comprise the contact body with conductive part, described conductive part is by the copper material bed of material that is connected on the described contact body, and the silver material layer that is connected on the contact surface that contacts for door lock electric switch contact on the described copper material bed of material constitutes.
2. door lock of elevator switch contact as claimed in claim 1, it is characterized in that, an end face of described contact body has hierarchic structure, the described copper material bed of material is connected in two planes on the described hierarchic structure and is connected on the vertical face between described two planes, and described silver material layer only is connected on described two planes.
