Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
The first embodiment is as follows:
as shown in fig. 1 to 3, an embodiment of the present invention provides a point contact connector, which includes an upper terminal 12, a lower terminal 22, and a lifting device; the upper terminal 12 has a plurality of first contacts 121; the lower terminal 22 is provided with a plurality of second contacts 221, and the first contact 121 is matched with the second contacts 221; the lifting device is used for driving the upper terminal 12 to move so as to enable the first contact 121 and the second contact 221 to be connected or disconnected; wherein the first contact 121 and the second contact 221 are both rod-shaped, and the first contact 121 and the second contact 221 are coaxially arranged along the moving direction of the pulling device.
When the LED display screen is used, the upper terminal 12 and the lifting device are arranged on one LED display screen, the lower terminal 22 is arranged on the adjacent LED display screen, and when the lifting device drives the upper terminal 12 to move upwards, the first contact 121 and the second contact 221 are separated from each other, and the power supply and the signals of the two adjacent LED display screens are disconnected; when the lifting device drives the upper terminal 12 to move downwards, the first contact 121 is contacted with the second contact 221, and the power supply and the signal of the two adjacent LED display screens are connected. The first contact 121 and the second contact 221 each include a plurality of power terminals and a plurality of data terminals, and power supply and data communication are respectively achieved.

Example two:
when the LED display screen is installed, the first contact 121 and the second contact 221 are still in a separation state under the condition that the lifting device rotates in place due to installation accuracy errors or the influence of external force vibration in the using process; on the other hand, when the distance between two adjacent LED display screens is too small, the first contact 121 is easily pressed on the second contact 221 too much, which causes contact abrasion and even damage, therefore, in this embodiment, as shown in fig. 3 and 4, the LED display device further includes a top contact spring 23, the lower terminal 22 is provided with an installation groove, the second contact 221 is slidably disposed in the installation groove, one end of the top contact spring 23 is connected to the second contact 221, and the other end of the top contact spring 23 is connected to the installation groove. The data line and/or the power line are connected to the second contact 221 through the mounting groove. The top-touch spring 23 enables the second contact 221 to be flexibly connected, when the second contact 221 is pressed by the first contact 121, the second contact 221 can move inwards to form a yielding space, so that the upper terminal 12 is prevented from being damaged due to overlarge stress, meanwhile, the top-touch spring 23 exerts elastic force on the second contact 221, when the installation is carried out, the first contact 121 can be enabled to abut against the second contact 221 to form certain pressure, then the upper terminal 12 and the lower terminal 22 are located and installed, and when the LED display screen is vibrated or changed due to external force in the subsequent use process, the first contact 121 and the second contact 221 can be ensured to be in close contact.
It is to be understood that the above-described structure is not limited to the lower terminal 22 and the second contact 221. For better effect, the same structure may be adopted for the upper terminal 12 and the first contact 121, or only the upper terminal 12 and the lower terminal 22 are fixedly connected, and the above structure is only a preferred embodiment.
Example three:
on the basis of the second embodiment, the present embodiment further includes an upper holder 11 and a lower holder 21, the upper terminal 12 is slidably disposed on the upper holder 11, the lower terminal 22 is mounted on the lower holder 21, and the pulling device is connected between the upper terminal 12 and the upper holder 11.
Specifically, as shown in fig. 1 and 2, a sliding seat 111 is disposed on the upper support 11, and a sliding groove is disposed on the upper terminal 12, and the sliding groove is engaged with the sliding seat 111.
Further, a return spring 13 is included, one end of the return spring 13 is connected to the upper terminal 12, and the other end is connected to the upper support 11.
Further, as shown in fig. 5, in order to prevent the first contact 121 and the second contact 221 from being effectively conducted due to an error in the mounting accuracy of the LED display screen, in this embodiment, a guide hole 211 is formed in the lower support 21, a guide rod 122 is disposed on the upper support 11 at a position corresponding to the guide hole 211, the guide hole 211 is engaged with the guide rod 122, and the guide rod 122 is slidably disposed in the guide hole 211.
During installation, the guide rod 122 and the guide hole 211 are positioned, so that the guide rod 122 extends into the guide hole 211, and the first contact 121 and the second contact 221 are effectively conducted.
Example four:
on the basis of any one of the first to third embodiments, as shown in fig. 6 to 12, in this embodiment, the lifting device includes a lifting handle 14 and two pull rods 15, a base plate is mounted on the upper support 11, the base plate extends outward perpendicular to the upper support 11, one end of the lifting handle 14 is hinged to the base plate, a through hole is formed in the pull rod 15, a rotating shaft 16 penetrates through the through hole, the two pull rods 15 are located on two sides of the lifting handle 14, one end of the pull rod 15 is mounted on the rotating shaft 16, the other end of the pull rod 15 is hinged to the upper terminal 12, when the lifting handle 14 is turned outward, the pull rod 15 is driven to move outward and upward, and then the pull rod 15 is driven to move upward, when the pull rod 15 moves upward, the upper terminal 12 is driven to move upward, so that the first contact 121 is driven to move upward, the first contact 121 is disconnected from the second contact 221, and when the lifting handle 14 is turned inward, the action processes are opposite.
Example five:
preferably, as shown in fig. 7 to 12, the utility model further includes a limiting device, which includes a limiting plate 17, a blocking piece 30, a mounting post 32 and a torsion spring 31, the limiting plate 17 is formed by extending the base plate in a direction away from the upper support 11, the mounting post 32 is fixedly mounted on the lifting handle 14, a through abdicating groove is formed on the lifting handle 14, the blocking piece 30 passes through the abdicating groove, one end of the torsion spring 31 is mounted on the mounting post 32, the other end is mounted on the blocking piece 30, the limiting plate 17 has a hook portion, as shown in fig. 9, the blocking piece 30 has an abdicating portion 303 and a blocking portion 302; as shown in fig. 12, when the hook portion is engaged with the engaging portion 302, the hook portion blocks the blocking piece 30, and the blocking piece 30 blocks the movement of the lifting handle 14, so as to finally limit the rotation of the lifting handle 14, and prevent the lifting handle 14 from loosening during use, which would cause the first contact 121 and the second contact 221 to be separated; the separation blade 30 is provided with a shifting sheet 301 for conveniently pulling out the separation blade 30, when the separation blade needs to be detached, only the shifting sheet 301 needs to be pulled, the separation blade 30 moves towards one side, the clamping portion 302 and the hooking portion are staggered, the yielding portion 303 corresponds to the hooking portion, the hooking portion is clamped in the yielding portion 303, the yielding portion 303 is lower and staggered with the hooking portion, the hooking portion cannot block the yielding portion 303, therefore, the pulling handle 14 can be turned, and the detachment work after the use is finished is convenient.
