The utility model discloses a kind of injection molding spring-piece type travel switch structures, including metal clips, a bumping post is molded in the middle part of the metal clips, described metal clips one end is fixing end, it is welded on pcb board, the other end is free end, covering above copper conductive layer on pcb board, and the bumping post upper end is equipped with upper cover, after upper cover pushing, the bumping post together with metal clips downlink, the free end of the metal clips touch on pcb board cover copper conductive layer after, be connected to pcb board on galvanic circle.The injection molding spring-piece type travel switch structure of the utility model, structure type is simple, is processed by mold, has certain economy；The utility model keeps effective fitting of elastic slice, greatly improves the insulation resistance of system by injection molding shelves rod structure；The utility model metal clips uses sprung copper class alloy, has preferable elasticity, guarantees effective contact of switch；The utility model is directly welded on pcb board, is not necessarily to switching support and signal wire.
Description
Technical field
The utility model relates to new-energy automobile electric cabinet switches, are specifically designed a kind of injection molding spring-piece type travel switch knot
Structure.
Background technique
The high-voltage interlocking structure of high-pressure electric control box part at present, mostly individual travel switch structure, travel switch are
An individual component installs travel switch by individual exchanging structure, guarantees that travel switch is effectively contacted with upper cover,
When upper cover is opened, travel switch signal is triggered, cut-off signal is exported by way of harness to system, disconnects high input voltage.
In prior art application, is connected using the combination of spring, moulding, sheet metal component, harness, constitute current programme
Material quantity is more, and global reliability and economy are poor.Current programme needs to make individual supporting structure, and fixed journey system is opened
Structure is closed, need to guarantee that travel switch can effectively be contacted with cover board in view of travel switch contact is at a distance from cover board, need simultaneously
With individual harness, it is plugged on the socket of controller circuit board by connector.
Utility model content
The utility model aim is: providing a kind of novel injection molding spring-piece type travel switch structure, which is used for new energy
The high-voltage interlocking of automobile high-voltage electricity control box part is protected, which is directly welded on the pcb board of box house, high opening
When pressing box cover component, construction of switch is disconnected, and is exported cut-off signal to system by pcb board, is disconnected high input voltage, prevent people
Member's electric shock.Its structure is simple, and only 2 kinds of materials are constituted, better economy.
The technical solution of the utility model is:
A kind of injection molding spring-piece type travel switch structure, including metal clips, the metal clips middle part have been molded a gear
Column, described metal clips one end are fixing end, are welded on pcb board, the other end is free end, and the copper that covers on pcb board is led
Above electric layer, the bumping post upper end is equipped with upper cover, and after upper cover pushing, the bumping post is together with metal clips downlink, the metal
The free end of elastic slice touch on pcb board cover copper conductive layer after, be connected to pcb board on galvanic circle.
Preferably, after the galvanic circle is connected to controller system metal clips downlink, galvanic circle output conducting letter
Number to controller system, controller system, which passes through feedback system and controls input power, to be connected, and controller works normally；Remove upper cover
When, injection molding shelves column uplink under the rebound effect of metal clips disconnects the connection circuit on pcb board, and output is disconnected at this time
ON signal to controller system, feedback system cuts off input power, and controller can not work on power.
Preferably, the free end of the metal clips is spoon shape structure.
The utility model has the advantages that:
1. the injection molding spring-piece type travel switch structure of the utility model, structure type is simple, is processed by mold, has one
Fixed economy；
2. the utility model keeps effective fitting of elastic slice, greatly improves the exhausted of system by injection molding shelves rod structure
Edge resistance；
3. the utility model metal clips of the present invention uses sprung copper class alloy, have preferable elasticity, guarantees switch
Effective contact；
4. the utility model is directly welded on pcb board, it is not necessarily to switching support and signal wire.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and embodiments:
Fig. 1 is the schematic diagram of the injection molding spring-piece type travel switch structure of the utility model；
Fig. 2 is the scheme of installation of the injection molding spring-piece type travel switch structure of the utility model.
Specific embodiment
As illustrated in fig. 1 and 2, the injection molding spring-piece type travel switch structure of the utility model, including metal clips, the metal
A bumping post 1 is molded in the middle part of elastic slice 2, described metal clips one end is fixing end, is welded on pcb board 4, and the other end is spoon shape
The free end of structure, covering above copper conductive layer 3 on pcb board, the bumping post upper end are equipped with upper cover 5, push in upper cover 5
Afterwards, for the bumping post 1 together with 2 downlink of metal clips, the free end of the metal clips, which touches, covers copper conductive layer on pcb board
Afterwards, it is connected to the galvanic circle on pcb board.
The galvanic circle connects controller system, and after 2 downlink of metal clips, galvanic circle exports Continuity signal to controlling
Device system, controller system control input power by feedback system and connect, and controller works normally；When controller is in maintenance
Or other reasons, when needing to remove upper cover 5, injection molding shelves column 1 uplink under the rebound effect of metal clips 2 disconnects PCB
Connection circuit on plate 4 exports cut-off signal to controller at this time, and feedback system cuts off input power, and controller can not power on
Work.
The utility model structure is simple, and only 2 kinds of materials are constituted, better economy；The present invention program directly opens stroke
Pass is welded in control circuit board, is connected without other fixing pieces, is connected without additional harness, can be effectively improved the reliable of system
Property.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
People can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.It is all
According to the modification that the Spirit Essence of the utility model main technical schemes is done, should all cover in the protection scope of the utility model
Within.
