Pre-installed position card slot and lock position card slot are arranged in the spacing of setting, when buckle is plugged in pre-installed position card slot, connector
Expose the jack for being inserted into terminal between shell and locking plate, when buckle is plugged in the card slot of lock position, locking plate is in locking
Terminal is locked in connector case body by state.
Preferably, the secondary snap close piece is U-shaped fastener.
Preferably, projector distance of the spacing size of the setting equal to terminal insertion position to lock position.
Preferably, the number of the buckle is two, and two buckle the end for being symmetrically set in U-shaped fastener.
Preferably, the buckle is equipped with hook-shaped extension, which is equipped with lead-in angle and export angle.
Preferably, it is equipped in the pre-installed position card slot and lock position card slot and lead-in angle and exports what angle matched
Inclined-plane.
Preferably, the locking plate is set to the recess portion center of U-shaped fastener.
Preferably, the locking plate is flat structure.
Preferably, the lead-in angle and the range at export angle are 30~45 degree.
Compared with prior art, the utility model has the advantage that
(1) the utility model provides secondary lock construction for the interlocking terminal of high-tension connector, in product use process
Reliability and stability provide double shield；
(2) the secondary lock construction design of the utility model is simple, simplifies manufacturing process flow, reduces manufacturing cost,
Product quality and technology stability are improved simultaneously；
(3) the secondary lock construction compact of the utility model can save space for the high-tension connector of large volume, be convenient for
Realize other critical functions；
(4) secondary lock is preloaded on connector shell and is used for shipment by the utility model, can reduce independent shipment number of components
Amount reduces the production and assembly cost of client, increases product competitiveness；
(5) buckle in the utility model is the detachable buckle equipped with lead-in angle and export angle, repeats behaviour by hand
Make to open and close secondary lock, convenient for reprocessing, reduces product rejection rate.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
As shown in Figure 1 and Figure 2, the utility model relates to a kind of secondary lock constructions of high-tension connector, including connector shell
1 and secondary snap close piece 2.Connector shell 1 is equipped with the jack for being inserted into terminal 3.Secondary snap close piece 2 is equipped with buckle 5 and lock
Piece 6, connector shell 1 are equipped with the pre-installed position card slot 4 and lock position card slot 7 to match with the size of buckle 5, pre-install position
It sets card slot 4 and lock position card slot 7 to be arranged in a fixed spacing, the size of the spacing is equal to terminal insertion position to lock position
Projector distance.
Secondary snap close piece 2 is U-shaped fastener, and the number for buckling 5 is two, is respectively symmetrically set to the both side ends of U-shaped fastener.
Locking plate 6 is set to the recess portion center of U-shaped fastener, and locking plate 6 is flat structure.Buckle 5 for detachable type buckle, buckle 5 it is hook-shaped
The lead-in angle of extension 501 and the range at export angle are 30~45 degree, be caught in the hook-shaped extension 501 of buckle 5 immediately
