Embodiment Construction
[0026] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] A specific embodiment of a connector of the present invention, such as Figure 1-3 As shown, the connector housing 1 is included, the connector housing 1 is provided with a contact piece 100, and the connector housing 1 is also provided with a lock for locking the two when the connector and the matching connector 2 are connected. Secondary locking mechanism. Since the connector of the present invention mainly refers to a high-voltage interlock connector suitable for a high-voltage circuit, the present invention mainly extends the control circuit of the high-voltage interlock connector through two unlockings of the secondary lock mechanism. The time to pull out the connector ensures that the high-voltage circuit has enough time to disconnect, and avoids the danger caused by the short time for the operator to pull out the connector and the high-vol...

The invention provides a secondary lock mechanism and a connector using the secondary lock mechanism. The locking part of the secondary lock mechanism comprises a locking base which is provided with a torsion bar. The torsion bar is fixedly provided with first and second lock plates. The first and second lock plates are respectively provided with first and second locking ends and first and second unlocking ends which are arranged at the front and rear sides of the torsion bar. A lever is formed by the first and second lock plates with the torsion bar acting as a pivot. The first and second unlocking ends are arranged in a spaced way in a front-and-back direction or a left-and-right direction. The unlocking part comprises an unlocking base which is provided with first and second abutting blocks which are arranged in the spaced way. When the unlocking base moves, the unlocking base has a first lock plate unlocking position at which the second abutting block and the second unlocking end are matched in an abutting way and the first abutting block and the first unlocking end are staggered in the front-and-back direction, and has a second lock plate unlocking position at which the first abutting block and the first unlocking end are matched in the abutting way and the second abutting block and the second unlocking end are staggered in the front-and-back direction. The secondary lock mechanism is simple in structure, convenient to use and high in safety.
Description
technical field [0001] The invention relates to the field of connectors, in particular to a secondary lock mechanism and a connector using the secondary lock mechanism. Background technique [0002] The high-voltage interlock connector is a key component of the high-voltage electrical system, which is mainly used to conduct high-voltage circuits. In order to ensure that the internally connected high-voltage circuit will not cause danger to the operator when this connector is pulled out, it is generally necessary to set up an interlock structure so that the high-voltage circuit is disconnected in advance when the plug and socket are separated. For example, the Chinese utility model patent with the authorized announcement number CN203415738U and the authorized announcement date of 2014.1.29 discloses a high-voltage interlock connector. mechanism, the primary lock is hinged outside the plug housing, and a spring is provided on one side of the hinge point, and a hook hooked to ...
