The shield 200 is connected to the cover 100, and the first square groove and the second square groove form a space for placing the PCB board. The transition piece 300 is disposed on the first square groove. The transition piece 300 has a U-shaped hole with one open end, which penetrates the top and bottom of the transition piece 300. Four transition pieces 300 are disposed at the four corners of the first square groove. The outer wall of the transition piece 300 is connected to the inner wall of the cover 100, which is suitable for increasing the wall thickness of the four corners of the cover.

[0023] Specifically, such as Figures 1 to 2As shown, the recessed end cap structure specifically includes a cover body 100, a shield body 200, and a transition piece 300. The cover body 100 and shield body 200 are provided to accommodate the PCB board, thus requiring them to be able to hold the PCB board. Therefore, a first square groove is formed on the cover body 100, and a second square groove is formed on the shield body 200. To allow the first and second square grooves to connect, the first square groove is located at the bottom of the cover body 100, and the second square groove is located at the top of the shield body 200. This way, when the cover body 100 and the shield body 200 are connected, the first square groove... The first square groove and the second square groove cooperate to form a space in which the PCB board is placed. Because the four corners of the cover 100 may break under stress during production and installation, transition pieces 300 are provided. The transition pieces 300 are located within the first square groove and at the four corners of the cover 100, with their outer walls connected to the inner walls of the cover 100. Therefore, the shape of the transition piece 300 must be the same as the shape of the inner walls of the four corners of the cover 100 to ensure a better fit. To provide sufficient space for the PCB board while increasing the wall thickness at the corners of the cover 100, a U-shaped hole is provided on the transition piece 300.

Figure 1 As shown on the front, the top of the transition piece 300 is Figure 1 As shown on the back side, a "U"-shaped hole is made so that the inner wall of the transition piece has an arc structure. Only an arc structure can prevent cracking while increasing the wall thickness. Other shapes with sharp angles cannot meet this requirement.

[0024] In one possible implementation, the transition member 300 specifically includes a first body 310, a second body 320, and a third body 330; the inner wall of the first body 310 has a "U"-shaped structure, and the outer wall of the first body 310 is connected to the apex corner of the cover 100; the second body 320 is a snap-shaped structure with a through hole, and the second body 320 is disposed at one end of the first body 310, and the outer wall of the second body 320 is connected to the inner wall of the cover 100; the inner wall of the third body 330 has an arc-shaped structure, and the third body 330 is connected to the other end of the first body 310, the outer wall of the third body 330 is connected to the inner wall of the cover 100, and the inner wall of the third body 330 is connected to the inner wall of the first body 310.

[0025] Specifically, such as Figure 1As shown, the transition piece 300 specifically includes a first body 310, a second body 320, and a third body 330. Because a "U"-shaped hole is formed in the transition piece 300, the inner wall of the first body 310 has a "U"-shaped structure. The shape of the outer wall of the first body 310 is the same as the shape of the apex corner of the cover 100, and it can be cut according to the shape of the apex corner of the cover 100. The second body 320 is a block structure with a through hole. The second body 320 is connected to one end of the first body 310, and the third body 330 is connected to the other end of the first body 310. The specific shape of the third body 330 is as follows: Figure 1 As shown, the inner wall of the third body 330 is an arc structure, and the inner wall of the third body 330 is connected to the inner wall of the first body 310, making the whole structure present an "S" shape. Figure 1 As shown, the two transition pieces 300 on the same side are symmetrically arranged about the transverse central axis of the cover 100, or about the longitudinal central axis of the cover 100. It should be noted that transverse refers to... Figure 1 From left to right, vertical refers to Figure 1 From top to bottom.

[0026] In one possible implementation, the bottoms of the first main body 310 and the third main body 330 are both at a predetermined distance from the bottom of the cover 100, and the bottom of the second main body 320 is at a predetermined distance from the bottom of the first main body 310. A limiting member 400 is also included. The limiting member 400 is a square frame and is disposed on the top of the cover 200, connected to the inner wall of the cover 200. The height of the limiting member 400 is equal to the predetermined distance between the bottom of the first main body 310 and the bottom of the cover 100.

[0027] Specifically, such as Figures 1 to 2 As shown, to achieve precise alignment of the cover 100 and the housing 200 during installation, ensuring a preset distance between the bottom of the first main body 310 and the bottom of the third main body 330 and the bottom of the cover 100, a limiting member 400 is provided on the housing 200. To match the first square groove and the second directional groove, the limiting member 400 has a square frame structure. The limiting member 400 is located on the top of the housing 200 and connected to the inner wall of the housing 200. The limiting member 400, the bottom of the first main body 310, and the bottom of the third main body 330 are all at the same preset distance from the bottom of the cover 100, ensuring a better connection and fit between the cover 100 and the housing 200. It should be noted that the top of the housing 200 is... Figure 2 The front view shown shows the bottom of the cover 200. Figure 2 The back side is shown.

[0028] In one possible implementation, the outer wall of the transition member 300 has the same shape as the four apex corners of the cover 100, all being "L"-shaped. In this embodiment, as shown... Figure 1 As shown, the shape of the outer wall of the transition piece 300 and the shape of the four apex corners of the cover 100 are both "L" shaped, but this is not limited to this embodiment.

[0029] In one possible implementation, a connector 500 is further included. The connector 500 is disposed within the second square groove, and its position corresponds to that of the third body 330. The shape of the connector 500 is identical to that of the third body 330. A first through hole 331 is formed on the third body 330, and a second through hole is formed on the connector 500. The positions of the first and second through holes correspond to each other.

[0030] Specifically, such as Figures 1 to 2 As shown, a connector 500 is provided to connect the cover 100 and the cover 200. The connector 500 is disposed in the second square groove, and its position corresponds to that of the third main body 330, and its shape is the same as that of the third main body 330. To enable the connection between the two, a first through hole 331 is provided on the third main body 330, and a second through hole is provided on the connector 500. The positions of the first through hole and the second through hole are corresponding, and the connection between the cover 100 and the cover 200 is achieved by a bolt passing through the first through hole and the second through hole.

[0031] In one possible implementation, a third through hole and a fourth through hole are provided on the cover 100. The third through hole is located at the center of the cover, and the fourth through hole is located on one side of the third through hole and between two transition pieces on the same side.

[0032] Specifically, such as Figure 1 As shown, in order to enable the PCB board to connect with external signal components within the space, a third through hole is provided on the cover 100. The third through hole is a circular hole located at the center of the cover, allowing the signal components to pass through and connect to the PCB board. The PCB board also needs to connect to an external power supply, which provides power to the PCB board. Therefore, a fourth through hole is provided. The fourth through hole is a rectangular hole located on one side of the third through hole, between two transition pieces on the same side. The external power supply connects to the PCB board through the fourth through hole.

[0034] Specifically, such as Figure 1 As shown, in order to fix the PCB board in the space and prevent it from shifting, a sixth through hole is provided. There are four through holes, and the sixth through hole is located in the U-shaped groove. The PCB board is fixed and limited by bolts passing through the sixth through hole.

[0035] This application includes a cover 100, a cover 200, a transition piece 300, a limiting piece 400, and a connector 500. The cover 100 and cover 200 are provided to fix and limit the PCB board. The transition piece 300 is provided to prevent the cover 100 from breaking. The transition piece 300 increases the wall thickness at the top corner of the cover 100. The limiting piece 400 serves as a guide when the cover 100 and cover 200 are connected, ensuring precise alignment and improving work efficiency. The connector 500 is provided to enable the cover 100 to... To ensure the PCB board remains fixed within the space and prevent displacement, a sixth through hole is incorporated between the PCB board 0 and the cover 200. Four through holes are installed, each located within a U-shaped groove. Bolts are inserted through these holes to secure and limit the PCB board's position. This design not only resolves the technical issues of wall breakage during production or installation, leading to low efficiency and increased costs, but also addresses the problem of easy displacement of the cover 200 during installation due to the lack of a limiting mechanism, requiring precise alignment when screwing in screws and resulting in low work efficiency.
