Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 6 and 14, the connector 20 of the LED display device of the present embodiment includes: a power supply female terminal 30 and a power supply male terminal 40. The power supply female terminal 30 includes a female terminal seat 31 and a first conductive member 32 disposed in the female terminal seat 31. The power supply male terminal 40 includes a male terminal seat 41, a second conductive member 42 movably disposed in the male terminal seat 41, a link mechanism 43 capable of driving the second conductive member 42 to move, a pushing member 44 for pushing the link mechanism 43 to move, and a first elastic member 45 capable of resetting the second conductive member 42 after moving. The pushing member 44 pushes the link mechanism 43 to move to drive the second conductive member 42, so that the second conductive member 42 has a conducting position extending out of the male terminal seat 41 and conducting with the first conductive member 32. The first elastic member 45 applies a first elastic force to the second conductive member 42 in a direction away from the power supply female terminal 30 so that the second conductive member 42 has an open position retracted into the male terminal holder 41 and separated from the first conductive member 32. The link mechanism 43 includes a first link 431 and a second link 432, a first end of the first link 431 is hinged to the male end seat 41, a second end of the first link 431 abuts against a side of the second conductive member 42 away from the power supply female end 30, a first end of the second link 432 is hinged to a second end of the first link 431, and a second end of the second link 432 is connected with the pushing member 44.

With the technical solution of the present embodiment, the connector 20 of the LED display device includes: a power supply female terminal 30 and a power supply male terminal 40. The first elastic member 45 applies a first elastic force to the second conductive member 42 in a direction away from the power supply female terminal 30 so that the second conductive member 42 has a disconnected position retracted into the male terminal holder 41 and separated from the first conductive member 32. The pushing member 44 pushes the link mechanism 43 to drive the second conductive member 42 to move, so that the second conductive member 42 can be in contact with the first conductive member 32 to electrically connect the power supply female terminal 30 and the power supply male terminal 40. The power supply female end 30 is separated from the power supply male end 40, and the second conductive member 42 retracts into the male end seat 41 under the action of the first elastic force, so that the second conductive member 42 is prevented from being exposed out of the male end seat 41. The link mechanism 43 includes a first link 431 and a second link 432, a first end of the first link 431 is hinged to the male end seat 41, a second end of the first link 431 abuts against a side of the second conductive member 42 away from the power supply female end 30, a first end of the second link 432 is hinged to a second end of the first link 431, and a second end of the second link 432 is connected with the pushing member 44. The pushing member 44 is driven to drive the second end of the second connecting rod 432 to move, and since the first end of the first connecting rod 431 can only rotate, the hinge joint between the first end of the second connecting rod 432 and the second end of the first connecting rod 431 can move and rotationally move along an arc, so that the second end of the first connecting rod 431 can be abutted against the second conductive member 42, the second conductive member 42 moves towards the power supply female end 30, and the second conductive member 42 can be in contact with the first conductive member 32 to be conducted, so that the power supply female end 30 is electrically connected with the power supply male end 40. Therefore, the problem that a conducting wire is needed to realize electrical connection when two adjacent LED display units 10 are assembled in the related art is avoided, wiring in the LED display device is simplified, assembly between the two adjacent LED display units 10 is simpler and more convenient, and assembly efficiency is improved. Therefore, the technical scheme of the embodiment effectively solves the problem that the wiring between two adjacent LED display units in the related art is complex, so that the assembly efficiency is low.

In the present embodiment, the second conductive member 42 is in contact with the first conductive member 32 to electrically connect the power supply female terminal 30 and the power supply male terminal 40, so that the two adjacent LED display units 10 are connected without a conductive wire, i.e. hard-wired.

Further, the link mechanism 43 in the present embodiment is a crank slider mechanism in the related art. The first end of the first connecting rod 431 is hinged to the male end seat 41 to form a rotating pair; the pushing member 44 moves along a straight line, and the second end of the second link 432 is connected with the pushing member 44 to form a moving pair. In the present embodiment, due to the stroke limitation of the pusher 44, the moving track of the hinge of the first end of the second link 432 and the second end of the first link 431 is a partial circle, i.e., a circular arc.

As shown in fig. 3 to 9, the second conductive member 42 includes an insulator 421 movably disposed in the male terminal seat 41 and a conductive body 422 penetrating the insulator 421. The second end of the first link 431 is provided with a propping disc 46, and the propping disc 46 props against one side of the insulator 421, which is far away from the power supply female end 30. When the pushing member 44 drives the second end of the second connecting rod 432 to move, the abutting disc 46 of the second end of the first connecting rod 431 abuts against the insulator 421, so that the insulator 421 moves towards the power supply female end 30, the second conductive member 42 is located at the conducting position, and the conductive body 422 of the second conductive member 42 can be in contact with and conducted with the first conductive member 32 of the power supply female end 30. The abutting disc 46 reduces the abrasion of the second end of the first connecting rod 431 when abutting against the insulator 421, and prolongs the service life of the first connecting rod 431.

As shown in fig. 3 to 9, the pushing member 44 includes a pushing rod 441 movably passed through the insulator 421 and a supporting block 442 provided on the pushing rod 441. A support block 442 is located on a side of the insulator 421 facing away from the power supply female end 30, and a second end of the second link 432 is connected to the support block 442. Thus, the supporting block 442 can follow the pushing rod 441 and move the second end of the second connecting rod 432. The pushing member 44 is driven in a direction away from the power supply female end 30, the supporting block 442 moves in the direction away from the power supply female end 30, and drives the second end of the second connecting rod 432 to move in the direction away from the power supply female end 30, so that the abutting disc 46 hinged to the first end of the second connecting rod 432 can abut against the insulator 421, and the insulator 421 moves towards the power supply female end 30, so that the second conductive member 42 is in a conducting position.

As shown in fig. 3 to 13, the first elastic member 45 is disposed between the insulator 421 and the male socket 41, and the first elastic force is generated by the first elastic member 45 applying a force to the insulator 421 in a direction away from the power supply female terminal 30. After the power supply female end 30 is separated from the power supply male end 40, the insulator 421 receives the first elastic force, and the insulator 421 drives the second conductive member 42 to retract into the male end seat 41, so as to prevent the second conductive member 42 from being exposed out of the male end seat 41, thereby prolonging the service life and facilitating the next contact and conduction between the second conductive member 42 and the first conductive member 32.

In the present embodiment, after the power supply female terminal 30 is electrically connected to the power supply male terminal 40, the male terminal socket 41 is inserted into the female terminal socket 31. The plugging force of the male socket 41 and the female socket 31 is greater than the first elastic force, so that the male socket 41 and the female socket 31 are kept in a plugging state, and the power supply female terminal 30 is in contact with the power supply male terminal 40.

Further, as shown in fig. 3 to 13, the connector 20 of the LED display device further includes a second elastic member 48 disposed between the supporting block 442 and the male terminal block 41, and the second elastic member 48 applies a second elastic force to the supporting block 442 toward the power supply female terminal 30. After the power supply female end 30 is separated from the power supply male end 40 due to the second elastic member 48, the supporting block 442 can support the second conductive member 42 under the action of the second elastic member 48, and the supporting block 442 can keep a certain distance between the second conductive member 42 and the side wall of the male end socket 41 far away from the power supply female end 30 under the action of the second elastic member, so that when the pushing rod 441 drives the supporting block 442 to move, the supporting block 442 has a sufficient distance to move in the direction far away from the power supply female end 30. In order to facilitate the separation of the power supply female end 30 and the power supply male end 40, in the process that the second conductive member 42 moves from the on position to the off position, the first elastic force is greater than the second elastic force, and the insulator 421 receives a force in a direction away from the power supply female end 30, so that the insulator 421 drives the second conductive member 42 to retract into the male end seat 41. When the push rod 441 is not subjected to an external force and the power supply female terminal 30 is separated from the power supply male terminal 40, the insulator 421 is fixed in the male terminal holder 41 by the first elastic force and the second elastic force.

As shown in fig. 3 to 13, a stopper 443 is further disposed on the pushing rod 441, and the stopper 443 is located on a side of the male end seat 41 facing away from the power supply female end 30 and is in stopping engagement with the male end seat 41. The stopper 443 is provided to prevent the push rod 441 from coming off the male housing 41, so that the stopper 443 can move in a direction away from the power supply female terminal 30 or in a direction close to the power supply female terminal 30.

As shown in fig. 3 to 13, the link mechanism 43 further includes a third link 433 and a fourth link 434, a first end of the third link 433 is hinged to the male end seat 41, a second end of the third link 433 abuts against a side of the second conductive member 42 away from the power supply female end 30, a first end of the fourth link 434 is hinged to a second end of the third link 433, and a second end of the fourth link 434 is connected to the pushing member 44. In this embodiment, the second end of the third link 433 is provided with a contact disc 47, and the third contact disc 46 contacts against a side of the insulator 421 away from the power supply female end 30. The third link 433, the fourth link 434, and the abutting plate 47 operate in the same principle as the first link 431, the second link 432, and the abutting plate 46. A first end of the first link 431 and a first end of the third link 433 are located at both sides of the pusher 44, and a second end of the second link 432 and a second end of the fourth link 434 are located at both sides of the pusher 44. Therefore, the two sides of the pushing piece 44 are stressed more uniformly, so that the pushing piece 44 can move along the direction far away from the power supply female end 30 or the direction close to the power supply female end 30 more smoothly.

As shown in fig. 3 to 13, the length of the first link 431 is greater than or equal to the length of the second link 432. In this embodiment, the moving track of the second end of the first link 431 is: a circle having the first end of the first link 431 as a center and the length of the first link 431 as a radius. The increase in the length of the first link 431 is advantageous to increase the moving range of the second end of the first link 431, and to increase the distance of the abutting plate 46 on the second end of the first link 431 moving in the direction away from the power supply female end 30 or in the direction close to the power supply female end 30. In this way, on the premise of satisfying the moving distance of the abutting disc 46, the length of the second link 432 can be shortened as much as possible, so that the structure in the power supply male end 40 is more compact, and the volume of the power supply male end 40 is reduced.

As shown in fig. 3 to 13, the power supply female end 30 further includes a force application member 33 disposed on one side of the female end seat 31 facing the power supply male end 40, and the force application member 33 can be in driving engagement with the pushing member 44. When the power supply female end 30 is close to the power supply male end 40, the force application member 33 of the power supply female end 30 can drive the pushing member 44 to drive the supporting block 442 to move in a direction away from the power supply female end 30, so that the abutting disc 46 abuts against the insulator 421 to move towards the power supply female end 30, and the power supply female end 30 is in contact with the power supply male end 40. Thus, in the process that the power supply female end 30 is close to the power supply male end 40, the push piece 44 is not required to be driven by external force to realize the contact conduction of the power supply female end 30 and the power supply male end 40, the assembly steps between the two LED display units 10 are simplified, and the assembly efficiency is improved.

The present application further provides an LED display device, as shown in fig. 1 to 5, the LED display device includes a plurality of LED display units 10 and a connector 20 disposed between two adjacent LED display units 10, the connector 20 is the connector 20 of the LED display device, a power supply female end 30 of the connector 20 is disposed on a first side 11 of one LED display unit 10 of the two adjacent LED display units 10 adjacent to the other LED display unit 10, and a power supply male end 40 of the connector 20 is disposed on a second side 13 of the other LED display unit 10 of the two adjacent LED display units 10 adjacent to the one LED display unit 10. By using the connector 20 of the LED display device, in the process that the first side 11 is close to the second side 13, the power supply female end 30 can be in contact with the power supply male end 40, and the assembly efficiency is improved. Since the connector of the LED display device can solve the problem of low assembly efficiency due to complicated wiring between two adjacent LED display units in the related art, the LED display device having the connector of the LED display device can solve the same technical problem.

In the present embodiment, the force applying member 33 of the power supply female terminal 30 disposed on the first side 11 partially protrudes from the first side 11. During the process that the first side 11 approaches the second side 13, the part of the force application member 33 protruding from the first side 11 can drive the pushing member 44 of the power supply male end 40 on the second side 13. In the process that the first side 11 is far away from the second side 13, the force applied on the pushing member 44 gradually disappears, and the second conductive member 42 moves in the direction far away from the power supply female end 30 under the action of the first elastic member 45, so that the second conductive member 42 moves into the male end seat 41. In this way, in the assembling and disassembling processes of two adjacent LED display units 10, the power supply female terminal 30 and the power supply male terminal 40 can be automatically connected, automatically separated and reset without additional operation, so that the assembling or disassembling operation of two adjacent LED display units 10 by an operator is facilitated.

As shown in fig. 3 to 9, the first side edge 11 is provided with a first avoiding hole 12 for avoiding the first conductive member 32 of the connector 20, and the second side edge 13 is provided with a second avoiding hole 14 for avoiding the second conductive member 42 of the connector 20, so that the first conductive member 32 and the second conductive member 42 can pass through the first avoiding hole 12 and the second avoiding hole 14, and the power supply female terminal 30 and the power supply male terminal 40 are in contact conduction. The second side edge 13 is further provided with a third avoidance hole 15 for avoiding the pushing member 44 of the connector 20, and one end of the pushing member 44 can penetrate through the third avoidance hole 15, so that the force application member 33 can be in driving fit with the pushing member 44.

In this embodiment, a guiding protrusion is disposed in the male socket 41, and a guiding groove for guiding and matching with the guiding protrusion is disposed on the second conductive member 42. The guiding protrusion is guided and matched with the guiding groove, so that the second conductive member 42 can move more smoothly in a direction away from the power supply female end 30 or close to the power supply female end 30.
