Abstract

The utility model relates to a locking mechanism for a charging connector electromagnetic lock, which comprises an electromagnet, an electromagnet baffle plate, a fixed pin shaft, an upper limiting block, a lower limiting block, a mounting bracket, a safety hook, a torsion spring and a rotation shaft. The electromagnet baffle plate is arranged on the electromagnet; the upper limiting block is arranged on the electromagnet; the lower limiting block and the electromagnet are both arranged on the mounting bracket which is arranged on a charging connector socket; one end of a right-angle type electromagnet baffle plate is arranged on the electromagnet while the other end is limited by the upper and lower limiting blocks; and the safety hook and the torsion spring are arranged on the charging connector socket. The utility model has the advantages that the lock is reliable after the charging connector socket is plugged in the proper position, the safety hook on the charging connector socket can enter into the socket by overcoming the force of the torsion spring and then hook the socket under the action of the torsion spring force after the connector plug and the socket are plugged together, and the electromagnet drives the electromagnet baffle plate to lock the safety hook after the charging connector is electrified so as to ensure the reliable lock of the charging connector plug and socket in the using process.

Description

Charge connector electromagnetic lock locked mechanism

Technical field

The utility model is a kind of charge connector electromagnetic lock locked mechanism that is used for, and belongs to technical field of electric connectors.

Background technology

At present, the charging electric vehicle operating process be will have on the charging pile charging plug of cable insert the charging socket that is installed on the automobile, plug together put in place after, energized again, electric automobile enters charge mode, after charging finishes, charging plug is extracted from charging socket again.In above-mentioned charging process, may there be the interruption that causes charging process because of misoperation, cause device damage, so there is the hidden danger of electric shock accidents.

Summary of the invention

The purpose of this utility model is intended to overcome in actual charging process, the phenomenon that misoperation causes the charge connector plugs and sockets to throw off may take place, the defective that causes charging and interrupt, propose a kind ofly to plug together when putting in place when connector plug and socket, auxiliary catch on the plug hooks socket, drive the electromagnet block by the electromagnet on the socket again and pin auxiliary catch, thereby constituted the charge connector electromagnetic lock locked mechanism that plugs and sockets does not get loose in charging process.

Technical solution of the present utility model: comprise electromagnet, the electromagnet block, fixed pin shaft, upper limit position block, lower position block, mounting bracket, auxiliary catch, torsion spring and rotation axis, wherein the electromagnet block is installed on the electromagnet by fixed pin shaft, upper limit position block is installed on the electromagnet, lower limit and electromagnet are installed on the mounting bracket, mounting bracket is installed on the charge connector socket, one end of square electromagnet block is installed on the electromagnet by fixed pin shaft, the other end of square electromagnet block is spacing by upper limit position block and lower position block, and auxiliary catch and torsion spring are installed on the charge connector plug by rotation axis.

Advantage of the present utility model: guarantee that charge connector plugs together the back that puts in place and locks reliable.When connector plug and socket plug together when putting in place, the charge connector plug is insured after hook overcomes torsion spring power and enter the socket upper window, hooks the socket groove then under the active force of torsion spring.After the charge connector energising, electromagnet gets electric adhesive, drives the electromagnet block and moves, and blocks the auxiliary catch that hooks socket, makes auxiliary catch can not deviate from socket, thereby guarantees that charge connector plug, socket in use lock reliably.

Description of drawings

Fig. 1 has installed plugs and sockets of the present utility model to plug together back electromagnetic lock locked mechanism and pin the plug hook schematic diagram of insuring.

Fig. 2 has installed plug schematic diagram of the present utility model.

Fig. 3 has installed socket schematic diagram of the present utility model.

Among the figure 1 is charge connector socket, the 2nd, charge connector plug, the 3rd, electromagnet, the 4th, electromagnet block, the 5th, fixed pin shaft, the 6th, upper limit position block, the 7th, lower position block, the 8th, mounting bracket, the 9th, auxiliary catch, the 10th, torsion spring, the 11st, rotation axis, the 12nd, button, the 13rd, socket.

Embodiment

The contrast accompanying drawing, the structure of charge connector electromagnetic lock locked mechanism is made up of electromagnet 3, electromagnet block 4, fixed pin shaft 5, upper limit position block 6, lower position block 7, mounting bracket 8, auxiliary catch 9, torsion spring 10 and rotation axis 11, wherein electromagnet block 4 is installed on the electromagnet 3 by fixed pin shaft 5, upper limit position block 6 is installed on the electromagnet 3, lower position block 7 and electromagnet 3 are installed on the mounting bracket 8, and mounting bracket is installed on the charge connector socket 1.Square electromagnet block 4 one ends are installed on the electromagnet 3 by fixed pin shaft 5, and the other end is spacing by upper limit position block 6 and lower position block 7.Auxiliary catch 9 and torsion spring 10 are installed on the charge connector plug 2 by rotation axis 11.

Auxiliary catch 9 is on plug body, auxiliary catch 9 head rounding ofves, front end is provided with big chamfering on the socket 13, when charge connector plug and charge connector socket plug together, auxiliary catch 9 slides along the chamfering on the socket 13, go into groove after the active force that overcomes torsion spring 10 enters socket 13 upper window, under the active force of torsion spring, hook socket 13.After the charge connector energising, electromagnet 3 gets electric adhesive, driving electromagnet block 4 moves forward, block the auxiliary catch 9 that hooks socket 13, even this moment is to the button 12 downward application of forces, auxiliary catch 9 also can't be deviate from socket 13, thereby guarantees that charge connector plug, socket in use lock reliably.

When connector plug and socket plug together when putting in place, the charge connector plug is insured and is entered socket 1 after hook 9 overcomes the active force of torsion spring 10, hooks socket 1 then under the active force of torsion spring 10.

After the charge connector energising, electromagnet 3 gets electric adhesive, drives electromagnet block 4 and moves, and blocks the auxiliary catch 9 that hooks socket, makes auxiliary catch 9 can not deviate from socket 1, thereby plugs and sockets is reliably locked.

Charging finishes back charge connector outage, and electromagnet 3 outage backs drive electromagnet block 4 and move forward, and apply certain active force along direction shown in Figure 1 to button 12 this moment, plugs and sockets release after the auxiliary catch rotating certain angle, and plug can be deviate from socket.
