[0026] A rectangular connector is a connector with a substantially rectangular shape and a substantially rectangular mating surface, and is also an important category in the connector family. The pins 200 in the existing rectangular connector are usually arranged in a double-row structure, and the number of the pins 200 is small, which is difficult to meet the connection requirements of existing electrical components. In addition, the pins 200 of the conventional rectangular connector are usually hollow structures, and the connection with the external electrical components is mainly achieved by point contact. This connection method has poor seismic performance and is prone to poor contact under strong earthquake conditions, affecting the operation of the entire device.

[0027] Reference Figures 1 to 4The present application provides a rectangular connector, including an insulating shell 100 and a pin 200, the insulating shell 100 has a through cavity 101, a mounting platform 111 is provided inside the cavity 101, the pin 200 is a solid conductive structure, the pin 200 is fixed on the mounting platform 111, one end of the pin 200 extends into the cavity 101, and the other end of the pin 200 extends out of the cavity 101, and the end of the pin 200 extending into the cavity 101 is a planar structure.

[0028] This type of pin 200 is a solid structure, and the end thereof extending into the interior of the wall is a planar structure. Therefore, when connected to an external electrical component, it is a surface contact connection. Compared with traditional point contact, the surface contact connection has better earthquake resistance and can effectively prevent poor contact under strong earthquake conditions.

[0029] During the manufacturing process, the plug pin 200 is first fixed on the mold, and then glass liquid is poured into the mold. When the glass liquid solidifies to form the insulating shell 100, the plug pin 200 is also fixed inside the insulating shell 100 at the same time.

[0030] In the embodiment shown in the present application, four rows of pins 200 are fixed on the mounting platform 111 inside the cavity 101. Therefore, there are more pins and a higher degree of integration.

[0031] In some embodiments, the insulating housing 100 includes a connecting seat 110 and an assembly part 120 , the assembly part 120 is fixed on one side of the connecting seat 110 , and the cavity 101 passes through the connecting seat 110 and the assembly part 120 .

[0032] Specifically, the connecting seat 110 and the assembly part 120 are both rectangular structures, the assembly part 120 is smaller than the connecting seat 110, the assembly part 120 is fixed in the middle of one side of the connecting seat 110, the cavity 110 is a rectangular structure, which directly passes through the connecting seat 110 and the assembly part 120, the mounting platform 111 is fixed inside the end of the assembly part 120 away from the connecting seat 110, and each pin 200 is fixed on the mounting platform 111.

[0033] Reference Figure 4 In some embodiments, the height of each row of pins 200 extending to the inside of the cavity 101 is the same, and the height of the ends of the outermost two rows of pins 200 extending to the outside of the cavity 101 is less than the height of the ends of the inner two rows of pins 200 extending to the outside of the cavity 101. This makes it easier to connect the corresponding electrical components.

[0034] In order to facilitate docking with other electrical components, in some embodiments, one end of the pin 200 extending outside the cavity 101 is a step structure 210 .

[0035] Specifically, Figure 4As shown, one end of the pin 200 extending to the outside of the cavity 101 is ground into a step structure 210 by a grinding device, so that when docking with other electrical components, the contact area is larger, the contact is more stable, and the shock resistance is better.

[0036] One end of the pin 200 with the step structure 210 extends out of the assembly part 120, and one end of the pin 200 with the contact piece 220 extends into the cavity 310. During installation, the assembly part 120 is directly inserted into the corresponding electrical component, so that the rectangular connector is installed more firmly on the electrical component.

[0037] In some embodiments, a contact 220 is provided at one end of the pin 200 extending into the cavity 101. The contact 220 is a columnar structure, and the diameter of the contact 220 is larger than the diameter of the pin 200. The area of ​​the end of the pin 200 extending into the cavity 101 is further increased.

[0038] The contact piece 220 and the plug pin 200 are an integrated conductive structure.

[0039] In order to facilitate installation of the rectangular connector, in some embodiments, the connection seat 110 is provided with connection holes 112 , and the connection holes 112 are located on both sides of the cavity 101 .

[0040] Specifically, through-hole type connection holes 112 are provided on both sides of the cavity 101 of the connection base 110 . After the rectangular connector is connected to other electrical components, the fastening bolts are inserted into the connection holes 112 to fix the rectangular connector.

[0041] In some other embodiments, the connection holes 112 on both sides of the cavity 101 are distributed diagonally, so that the connection is more secure.

[0042] In order to facilitate the installation of the rectangular connector, in some embodiments, the connection base 110 is provided with positioning holes 113 , and the positioning holes 113 are located on both sides of the cavity 101 .

[0043] When installing the rectangular connector, first insert the two positioning holes 113 into the corresponding positioning holes 113 to pre-position the rectangular connector, and then insert the fastening bolts into the connecting holes 112 to fix it.

[0044] In some other embodiments, the positioning holes 113 on both sides of the cavity 101 are distributed diagonally, so that the positioning is more accurate.
