Interlocking switch socket

Technical Field

The application relates to the technical field of switch sockets, in particular to an interlocking switch socket.

Background

In the industrial application, in order to facilitate the circuit connection of equipment and the control of the circuit, some switch assemblies combining a socket and a switch appear on the market.

Generally, a switch socket consists of a shell, a switch component arranged in the shell, a socket component and an industrial plug matched with the socket component for use, so that the industrial plug and a positioning block are inserted into the socket component for matching use, when the switch component is shifted to a position on the shell, which shows on, the industrial plug is communicated with the socket component to power on the industrial plug, and when the switch component is shifted to a position on the shell, which shows off, the industrial plug is powered off.

In the above-described related art, the inventors consider that: when not using switch socket, the switch module on the switch socket can be twisted and the socket circular telegram is carried out for switch socket is electrified when the industry plug has not inserted yet, leads to the potential safety hazard easily.

SUMMERY OF THE UTILITY MODEL

In order to improve the safety of the use of the switch socket, the aim of the application is to provide an interlocking switch socket.

The application provides an interlocking type switch socket adopts following technical scheme:

the utility model provides an interlocking type switch socket, include the casing, rotate set up in switch on the casing, set up in socket on the casing and with socket assorted plug, seted up on the casing and supplied the plug inserts socket in the socket, the switch is located one end coaxial coupling in the casing has the lock dish, articulated in the casing have articulated axis with switch rotation axis looks vertically jam plate, seted up on the lock dish and supplied the draw-in groove that jam plate tip card was gone into, the jam plate is kept away from the one end of lock dish extends to socket below and plug looks butt, be equipped with the butt in the casing the jam plate card is gone into the piece that supports of draw-in groove.

Through adopting above-mentioned technical scheme, when not inserting the plug yet, the switch rotates the position of closing on the casing, supports the tight piece and upwards supports the movement with the one end that the jam plate is close to the socket for the one end that the jam plate is close to the switch rotates downwards, and with in the draw-in groove of jam plate card income lock dish, with the rotation of restriction switch.

When inserting the plug into the socket in the socket, the plug butt jam plate supports the one end that the jam plate is close to the socket and moves in the casing to the one end that is close to the switch with the jam plate rotates up, makes the jam plate break away from the draw-in groove of locking disc, in order to relieve the locking of switch in the casing, and then realizes inserting the plug and relieve the locking of switch. Consequently, through the joint that sets up jam plate and lock dish, utilize the plug to insert the socket and drive the jam plate and rotate to relieve the joint of jam plate and lock dish, make socket switch just can open the switch circular telegram after inserting the plug, thereby improve the security that switch socket used.

Optionally, be equipped with the support in the casing the backup pad of socket and switch, the backup pad is located offer the confession on the lateral wall of lock dish below the jam plate pivoted rotates the groove, support tight including the card go into rotate the inslot and be the flexure arrangement's flexure strip, flexure strip one end butt in the jam plate is close to the diapire of plug, the other end butt in rotate the groove cell wall.

Through adopting above-mentioned technical scheme, when being close to the draw-in groove of lock dish one end card income with the jam plate, the flexure strip is crooked "U" type, and the one end butt that the flexure strip is close to the jam plate is in the diapire of jam plate, and the one end butt that the jam plate was kept away from to the flexure strip is in the cell wall that rotates the groove for the flexure strip produces bending deformation. With the diapire of restoring force butt in the jam plate through the flexure strip for the jam plate is close to socket one end and upwards rotates, is close to the one end of locking dish and rotates downwards, in order to block the jam plate card into the draw-in groove, fixes the rotation of switch. When the plug is inserted into the socket, the plug supports the end, close to the socket, of the locking plate downwards, so that the end, close to the socket, of the locking plate is rotated into the rotating groove by rotating the end, located at the hinged shaft, of the locking plate, the lower end of the elastic piece is extruded towards the rotating groove, the end, close to the locking disc, of the locking plate upwards rotates and is separated from the clamping groove, and locking of the switch is relieved. Consequently through setting up the flexure strip, utilize the bending deformation of flexure strip for the plug inserts the joint separation of jam plate extrusion flexure strip with jam plate and lock dish, extracts behind the plug that the flexure strip resumes deformation and blocks the jam plate into the lock dish once more, thereby is convenient for the auto-lock of switch.
