DETAILED DESCRIPTION

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0036] like Figures 1 to 13 As shown, the energy storage device connector with an anti-short circuit structure described in this embodiment includes a female connector; the female connector includes a female plastic body 11; the energy storage device connector also includes a male connector for electrically plugging and mating with the female connector; the male connector includes a male plastic body 21.

[0037] The female plastic body 11 includes a first body 111 and a second body 112 fixed on the first body 111; at least two groups of first terminal groups are arranged in the female plastic body 11; the number of first terminal groups can be freely set according to actual application needs, such as two groups of first terminal groups are arranged in this embodiment; each group of first terminal groups includes two first contact terminals 12 arranged oppositely; one end of the first contact terminal 12 is arranged on the first body 111, and the other end of the first contact terminal 12 is arranged on the second body 112.

[0038] The female plastic body 11 is provided with a switching component and a thermal drive component corresponding to each group of first terminals; the switching component includes a switching shaft 131 rotatably arranged between the two first contact terminals 12, and two insulating blocks 132 and two second contact terminals 133 both arranged on the switching shaft 131; the two insulating blocks 132 and the two second contact terminals 133 are alternately and evenly distributed on the switching shaft 131 along the circumferential direction; the thermal drive component includes an insulating heat-conducting frame 141 in contact with the first contact terminals 12, a switching push rod 142 slidably arranged on the insulating heat-conducting frame 141, and a thermal spring 143 arranged between the insulating heat-conducting frame 141 and the switching push rod 142.

[0039] When the temperature of the thermistor spring 143 reaches its deformation threshold, the thermistor spring 143 deforms and pushes the switch push rod 142 to slide. The switch push rod 142 drives the switch shaft 131 to rotate, so that the two insulating blocks 132 rotate to contact the two first contact terminals 12, thereby cutting off the power circuit.

[0040] The male plastic body 21 has a cavity, and at least two plug pins 22 are arranged in the cavity; the number of the plug pins 22 is arranged in a one-to-one correspondence according to the switching shaft 131 of the female connector.

[0041] Specifically, when the energy storage device connector of this embodiment is operating normally in the power-on circuit, the male connector is electrically plugged into the female connector, that is, when the temperature of the thermal spring 143 does not reach its deformation threshold, the thermal spring 143 does not deform, the switch push rod 142 does not drive the switch shaft 131 to rotate, and the two second contact terminals 133 on the switch shaft 131 are electrically connected to the two first contact terminals 12 in a one-to-one correspondence, and the pin 22 is electrically connected to the first contact terminal 12 through the second contact terminal 133, thereby completing the power-on circuit;

[0042] When a short circuit occurs in the power-on circuit, the temperature of the first contact terminal 12 increases, and the heat on the first contact terminal 12 is conducted to the thermistor spring 143 via the insulating heat-conducting frame 141, causing the temperature of the thermistor spring 143 to increase. When the deformation threshold of the thermistor spring 143 is reached, the thermistor spring 143 is deformed and pushes the switching push rod 142 to slide. During the sliding process of the switching push rod 142, the switching shaft 131 is pushed to rotate ninety degrees, so that the second contact terminal 133 is staggered from the first contact terminal 12, and the two insulating blocks 132 are in contact with the two first contact terminals 12 one by one, so that the first contact terminal 12 is electrically disconnected from the pin 22, thereby cutting off the power-on circuit.

[0043] In this embodiment, the thermal spring 143 is arranged so that it can be quickly heated and deformed when a short circuit occurs, thereby pushing the switching push rod 142 to slide, so that the switching shaft 131 drives the insulating block 132 and the second contact terminal 133 to rotate, and then the insulating block 132 is brought into contact with the first contact terminal 12, thereby realizing automatic disconnection of the electrical connection of the connector, thereby helping to improve the safety and reliability of the energy storage device connector.

[0044] Preferably, the second contact terminal 133 is elastically connected to the switching shaft 131 so that when the second contact terminal 133 is in electrical contact with the first contact terminal 12 , the second contact terminal 133 can maintain contact with the first contact terminal 12 , thereby improving the reliability of the electrical connection.

[0045] In the energy storage device connector of this embodiment, in some embodiments, the switching shaft 131 is made of a conductive material, and the switching shaft 131 has a socket 1311. Specifically, the second body 112 is provided with a socket at a position corresponding to each socket 1311. When the male connector is plugged into the female connector, the pin 22 is inserted into the socket 1311 through the socket, thereby being electrically connected to the switching shaft 131. When the second contact terminal 133 contacts the first contact terminal 12, the pin 22 is connected to the first contact terminal 12 through the switching shaft 131 and the second contact terminal 133, thereby achieving electrical conduction between the male connector and the female connector. By providing the socket 1311 to cooperate with the pin 22, the electrical connection between the male connector and the female connector is made more secure.

[0046] Preferably, the second body 112 is provided with clamps 18 on both sides of each plug hole 1311; the clamps 18 are provided to clamp and fix the plug pins 22, thereby further improving the reliability of the electrical connection between the male connector and the female connector.

[0047] In the energy storage device connector of this embodiment, in some embodiments, the switching assembly also includes a guide sleeve 134 fixedly connected to one end of the switching shaft 131; the inner wall of the guide sleeve 134 is provided with a driving groove; one end of the switching push rod 142 is elastically provided with a bayonet 1421; when the temperature of the thermistor spring 143 reaches its deformation threshold, the switching push rod 142 drives the bayonet 1421 to slide, and makes the bayonet 1421 embedded in the driving groove, thereby driving the guide sleeve 134 to drive the switching shaft 131 to rotate, so that through the cooperation of the bayonet 1421 and the driving groove, the linear motion of the switching push rod 142 is converted into the rotational motion of the guide sleeve 134, thereby realizing the position switching of the insulating block 132 and the second contact terminal 133.

[0048] In this embodiment, the driving groove includes a plurality of spiral grooves 1341 and a plurality of vertical grooves 1342 which are connected alternately end to end; an entrance groove 1343 penetrating the guide sleeve 134 is provided at the intersection of the end of the vertical groove 1342 close to the switching push rod 142 and the end of the spiral groove 1341 close to the switching push rod 142; a first step 1344 is provided at the intersection of the entrance groove 1343, the spiral groove 1341 and the vertical groove 1342, so that the locking pin 1421 moves along the trajectory of the spiral groove 1341 after entering from the entrance groove 1343; a second step 1345 is provided at the intersection of the end of the vertical groove 1342 away from the switching push rod 142 and the end of the spiral groove 1341 away from the switching push rod 142.

[0049] Specifically, the number of the spiral groove 1341 and the vertical groove 1342 are both four, and the number of the entrance groove 1343 is also correspondingly set to four; when the thermal spring 143 pushes the switching push rod 142 to slide, the switching push rod 142 drives the bayonet 1421 to move until the bayonet 1421 enters from the entrance groove 1343. As the bayonet 1421 moves further, the first step 1344 blocks the bayonet 1421 from entering the corresponding vertical groove 1342, so that the bayonet 1421 enters the corresponding spiral groove 1341 from the entrance groove 1343. At this time, the bayonet 1 421 and the spiral groove 1341, the guide sleeve 134 drives the switching shaft 131 to rotate until the bayonet 1421 enters the vertical groove 1342 from the spiral groove 1341. At this time, the guide sleeve 134 drives the switching shaft 131 to rotate ninety degrees, and at the same time the second step 1345 blocks the bayonet 1421 from retreating into the spiral groove 1341, so that the insulating block 132 rotates to contact the first contact terminal 12, thereby automatically disconnecting the electrical connection between the male connector and the female connector, thereby cutting off the power circuit to ensure the safety of the energy storage device.

[0050] In the energy storage device connector of this embodiment, in some embodiments, the thermal drive component includes a slide seat 144 slidably arranged on an insulating heat-conducting frame 141; an elastic telescopic rocker 145 is hinged between the insulating heat-conducting frame 141 and the switching push rod 142; the two ends of the thermistor spring 143 are respectively connected to the slide seat 144 and the insulating heat-conducting frame 141; when the temperature of the thermistor spring 143 does not reach its deformation threshold, the switching push rod 142 and the slide seat 144 are movably abutted.

[0051] Specifically, when the power-on circuit is working normally, the temperature of the thermistor spring 143 is not enough to reach its deformation threshold, and the elastic telescopic swing rod 145 makes the switching push rod 142 remain in contact with the slide seat 144; after the temperature of the thermistor spring 143 reaches the deformation threshold and is deformed, the thermistor spring 143 pushes the slide seat 144 to move, and since the switching push rod 142 is in contact with the slide seat 144, the slide seat 144 pushes the switching push rod 142 to overcome the elastic force of the elastic telescopic swing rod 145 and move, until the elastic telescopic swing rod 145 passes the hinge point position between it and the insulating heat-conducting frame 141, and the switching push rod 142 is in contact with the slide seat 144 under the elastic force of the elastic telescopic swing rod 145. The switch push rod 142 continues to slide under the force, so that the bayonet 1421 is quickly inserted into the entrance groove 1343 and moves relatively along the trajectory of the spiral groove 1341, so that the switch shaft 131 is quickly rotated ninety degrees, so that the second contact terminal 133 is staggered from the first contact terminal 12, and then the insulating block 132 isolates the electrical connection between the first contact terminal 12 and the pin 22 to ensure the safety of the energy storage device; at the same time, under the elastic force of the elastic telescopic rocker 145, the switch push rod 142 keeps the bayonet 1421 in cooperation with the vertical groove 1342 to avoid high temperature repeatedly triggering the rotation of the switch shaft 131 and causing unstable operation of the equipment.

[0052] That is to say, when the thermal spring 143 recovers its elastic deformation, the thermal spring 143 can drive the slide 144 to return to its original position, while the switch push rod 142 cannot return to its original position following the slide 144 under the elastic force of the elastic telescopic rod.

[0053] It should be noted that the deformation of the thermal spring 143 pushes the switching push rod 142 to move the stroke, which can make the elastic telescopic swing rod 145 pass the hinge point position between it and the insulating heat-conducting frame 141. Of course, the deformation of the thermal spring 143 can also be set to continue to provide thrust for the switching push rod 142 after the elastic telescopic swing rod 145 passes the hinge point position between it and the insulating heat-conducting frame 141, so as to have a greater driving force to drive the switching shaft 131 to rotate, that is, after the elastic telescopic swing rod 145 passes the hinge point position between it and the insulating heat-conducting frame 141, the sliding seat 144 can be separated from the abutment and cooperation with the switching push rod 142, and can also continue to maintain the abutment and cooperation with the switching push rod 142.

[0054] In the energy storage device connector of this embodiment, in some embodiments, the number of the elastic telescopic swing rods 145 is two, and the two elastic telescopic swing rods 145 are symmetrically distributed on both sides of the switching push rod 142. In this embodiment, by setting two elastic telescopic swing rods 145 to be hinged with the switching push rod 142, the switching push rod 142 is subjected to a more balanced force, and after the elastic telescopic swing rod 145 passes the hinge point position between it and the insulating heat conductive frame 141, the two elastic telescopic swing rods 145 can push the switching push rod 142 to slide more quickly, providing a greater thrust for the switching push rod 142, so as to drive the switching shaft 131 to rotate reliably.

[0055] Preferably, the elastic telescopic rocker arm 145 comprises a first rocker arm, a second rocker arm and a rocker arm spring; one end of the first rocker arm is hinged on the insulating heat-conducting frame 141, one end of the second rocker arm slides into the other end of the first rocker arm, the other end of the second rocker arm is hinged on the switching push rod 142, the rocker arm spring is sleeved on the outer walls of the first rocker arm and the second rocker arm, and the two ends of the rocker arm spring are respectively abutted against one end of the first rocker arm and the other end of the second rocker arm, so that the second rocker arm has elastic telescopic performance.

[0056] In the energy storage device connector of this embodiment, in some embodiments, the female plastic body 11 is slidably penetrated with a handle 15; the switching push rod 142 can pass through the slide seat 144; the handle 15 is fixedly connected to the switching push rod 142 of each set of thermal drive components. In this embodiment, a handle 15 is provided so that the user can manually push the switching push rod 142 to move through the handle 15; in particular, when the switching shaft 131 rotates to make the insulating block 132 cut off the electrical connection between the male connector and the female connector, the user can inspect the power circuit. After the power circuit is in a normal state, the handle 15 can be pulled to make the switching push rod 142 overcome the elastic force of the rocker spring and move, and the latch 1421 moves along the vertical groove 1342 and escapes through the entrance groove 1343, so that the latch 1421 is disengaged from the driving groove. After the elastic telescopic rocker 145 passes the hinge point position between it and the insulating heat conductive frame 141, the rocker spring applies thrust to the switching push rod 142 to accelerate the resetting of the switching push rod 142, that is, the user can restore the electrical connection between the male connector and the female connector by pushing and pulling the handle 15 without plugging and unplugging the male connector.

[0057] In the energy storage device connector of this embodiment, in some embodiments, at least two groups of second terminal groups corresponding to the first terminal groups are further provided in the female plastic body 11; each group of second terminal groups includes two third contact terminals 135 arranged opposite to each other; the two third contact terminals 135 of the second terminal group and the two first contact terminals 12 of the corresponding first terminal group are evenly distributed on the outer periphery of the switching shaft 131 in a cross shape; when the temperature of the thermal spring 143 reaches its deformation threshold, the switching shaft 131 rotates to make the two insulating blocks 132 contact with the two first contact terminals 12, and to make the two second contact terminals 133 electrically contact with the two third contact terminals 135.

[0058] In this embodiment, a second terminal group is provided so that when the thermistor spring 143 is deformed to push the switching push rod 142 to slide, the switching shaft 131 rotates to make the two insulating blocks 132 contact with the two first contact terminals 12, and the two second contact terminals 133 electrically contact with the two third contact terminals 135, thereby cutting off the power circuit and connecting the alarm circuit through the electrical conduction between the second contact terminals 133 and the third contact terminals 135, so as to generate an alarm signal to prompt the user.

[0059] In the energy storage device connector of this embodiment, in some embodiments, the sliding sleeve of the female plastic body 11 is provided with a shell 16; a reset spring 17 is connected between the shell 16 and the female plastic body 11; an elastic tongue 1111 is torn and formed on the top of the female plastic body 11, and a locking boss 1112 and an unlocking boss 1113 arranged at intervals are convexly provided on the elastic tongue 1111; the inner top wall of the male plastic body 21 is provided with a buckle groove 211 for snap-fitting with the locking boss 1112; a buckle hole 161 is provided on the top of the shell 16; and the unlocking boss 1113 is movably embedded in the buckle hole 161.

[0060] Specifically, when the male connector and the female connector are plugged in and mated, the male plastic body 21 is pressed against the shell 16, so that the shell 16 slides relative to the female plastic body 11, the return spring 17 is compressed, and the pin 22 is inserted into the socket 1311 through the socket. During the insertion process, the male plastic body 21 presses the elastic tongue 1111 through the locking boss 1112, so that the elastic tongue 1111 is deformed until the locking boss is snapped into the buckle groove 211. At this time, the locking boss cooperates with the buckle groove 211 to lock the male connector and the female connector, and the plug-in fixation of the male connector and the female connector is completed;

[0061] When the male connector needs to be unplugged, the user manually pushes the shell 16 to continue squeezing the reset spring 17, so that the shell 16 squeezes the elastic tongue 1111 through the unlocking boss 1113 to deform, so that the locking boss 1112 moves out of the buckle groove 211, thereby completing the unlocking, and the male connector can be unplugged at this time.

[0062] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
