Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0031] First, as Figure 1 , Figure 2 as well as Figure 3 The utility model provides a digital display screen test socket, comprising a test circuit board 1, a mounting block 2 and a plurality of connectors 3.

[0032] A plurality of pins 11 are provided on one side of the test circuit board 1. The plurality of pins 11 are arranged in two parallel rows. Each pin 11 is electrically connected to the printed circuit on the test circuit board 1. A plurality of sockets 21 are provided on the mounting block 2. The plurality of sockets 21 are arranged in two parallel rows and correspond to the two rows of pins 11. A plurality of connectors 3 are respectively embedded in the plurality of sockets 21. Each connector 3 includes a first elastic sheet 31 and a second elastic sheet 32. The first elastic sheet 31 and the second elastic sheet 32 ​​are arranged opposite to each other. A width-adjustable accommodation position 33 is formed between the first elastic sheet 31 and the second elastic sheet 32. Both the first elastic sheet 31 and the second elastic sheet 32 ​​are electrically connected to the printed circuit on the test circuit board 1.

[0033] In a specific application, the pins of the digital display screen are aligned with the sockets 21 on the mounting block 2 and inserted therein, and the pins of the digital display screen are inserted into the accommodating positions 33. Since the first elastic sheet 31 and the second elastic sheet 32 ​​are both elastic, the first elastic sheet 32 ​​and the second elastic sheet 32 ​​clamp the pins of the digital display screen, so that the digital display screen is connected to the printed circuit on the test circuit board 1, so that each digital display screen can be powered on for power-on testing, thereby avoiding the situation where the pins of the digital display screen are inserted into the sockets 21 but the digital display screen is not connected to the printed circuit on the test circuit board 1, thereby improving the yield of the product.

[0034] In some preferred embodiments, the first elastic sheet 31 and the second elastic sheet 32 ​​both have an arc segment 311, and the arc segment 311 bends toward the inside of the insertion hole 21, so that the width of the accommodation position 33 gradually decreases and then gradually increases from top to bottom. In specific applications, by providing the arc segment 311 that bends toward the inside of the insertion hole 21 on both the first elastic sheet 31 and the second elastic sheet 32, a smaller accommodation position 33 can be formed between the first elastic sheet 31 and the second elastic sheet 32, further ensuring that the first elastic sheet 31 and the second elastic sheet 32 ​​can clamp the pins of the digital display screen.

[0035] In some preferred embodiments, the side wall of the above-mentioned jack 21 is provided with two opposite protrusions 211, and one end of the first elastic sheet 31 away from the test circuit board 1 and one end of the second elastic sheet 32 ​​away from the test circuit board 1 respectively abut against the two opposite protrusions 211. In a specific application, the protrusions 211 are used to limit the end of the first elastic sheet 31 away from the test circuit board 1 and the end of the second elastic sheet 32 ​​away from the test circuit board 1, so as to prevent the pins of the digital display screen from pulling the first elastic sheet 31 and the second elastic sheet 32 ​​out of the jack 21 when the pins of the digital display screen are pulled out of the jack 21.

[0036] In some preferred embodiments, the width between the adjacent sides of the two opposite protrusions 211 gradually decreases from top to bottom. In specific applications, by designing the width between the adjacent sides of the two opposite protrusions 211 to gradually decrease from top to bottom, when the first elastic sheet 31 and the second elastic sheet 32 ​​are installed in the insertion hole 21, the adjacent sides of the two protrusions 211 can guide the pins of the digital display screen, so that the pins of the digital display screen can be inserted more accurately.

[0037] like Figure 4 As shown, in some preferred embodiments, each of the connectors 3 further includes a connecting piece 34, the connecting piece 34 is electrically connected to the printed circuit on the test circuit board 1, and the first elastic piece 31 and the second elastic piece 32 are both connected to the connecting piece 34. In a specific application, the first elastic piece 31 and the second elastic piece 32 are connected by the connecting piece 34, so that when the connector 3 is installed in the socket 21, it is more convenient to install.

[0038] In some preferred embodiments, the first elastic sheet 31, the second elastic sheet 32 ​​and the connecting sheet 34 are integrally formed. By designing the first elastic sheet 31, the second elastic sheet 32 ​​and the connecting sheet 34 to be integrally formed, production and processing are more convenient.

[0039] In some preferred embodiments, both ends of the test circuit board 1 are provided with mounting positions 12. In specific applications, screws or bolts can be used to pass through the mounting positions 12 to fix the test circuit board 1 at a predetermined position.

[0040] Second, as Figure 5 As shown, the utility model provides a testing device, comprising the digital display screen test socket of the first aspect.

[0041] In some preferred embodiments, the test device further comprises a bottom plate 4, and the number of digital display screen test sockets is two, and the two digital display screen test sockets are relatively arranged on the bottom plate 4 and can move toward or away from each other. In specific applications, by arranging two digital display screen test sockets that can move toward or away from each other on the bottom plate 4, the test device can perform power-on tests on digital display screens of different widths, which greatly improves the scope of application of the test device.

[0042] In some preferred embodiments, the bottom plate 4 is provided with an elongated hole 41, and the test circuit board 1 is connected to the elongated hole 41 by a fastening bolt 5. In a specific application, one end of the fastening bolt 5 sequentially passes through the mounting position 12 and the elongated hole 41 to realize the connection between the test circuit board 1 and the bottom plate 4. When the distance between the two digital display screen test sockets needs to be adjusted, the fastening bolt 5 is loosened to slide along the length direction of the elongated hole 41. After the fastening bolt 5 drives the test circuit board 1 to slide to a predetermined position, the fastening bolt 5 is tightened again to connect and fix the test circuit board 1 and the bottom plate 4 together again.

[0043] In summary, the digital display screen test socket and test device of the utility model arrange a connector 3 in the socket 21, so that the first elastic sheet 31 and the second elastic sheet 32 ​​of the connector 3 can clamp the pins of the digital display screen inserted into the socket 21, thereby avoiding the situation where the pins of the digital display screen are inserted into the socket 21 but the digital display screen is not connected to the printed circuit on the test circuit board 1, thereby ensuring that each digital display screen can be connected to the printed circuit on the test circuit board 1 for power-on testing, so as to improve the yield of the product.

[0044] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
