[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 6As shown, a rectangular connector for connecting with a PCB of the present invention comprises a male head and a female head. When in use, the male head is fixedly arranged on the PCB board. The male head comprises a plug 1 and a plug cover 2. A plurality of pins 3 are arranged between the plug 1 and the plug cover 2. The female head comprises a socket 4 and an outer frame 5. A pin hole 6 corresponding to each pin 3 is arranged in the socket 4. A pin mounting block 7 is arranged on the plug cover 2. Each pin 3 comprises a PCB connection end and a socket connection end. The pin 3 is arranged on the pin mounting block 7. Each pin 3 is L-shaped, wherein the PCB connection end is used to connect with the PCB board, the socket connection end is connected to the socket 4, and the size of the PCB connection end and the socket connection end are different. The preferred embodiment is that the size of the PCB connection end is smaller than that of the socket connection end. A bayonet 13 is arranged at both ends of the plug 1, and a buckle 21 corresponding to the bayonet 13 is arranged at both ends of the plug cover 2. The buckle 21 is a boss. A connection hole is arranged on the bayonet 13, and the connection hole is adapted to the boss. Baffles are provided on both sides of the buckle 21. After the bayonet 13 is connected to the buckle 21, it is located between the baffles on both sides of the buckle 21. A docking component is provided on both sides of the plug cover 2 or on the side opposite to the PCB connection end of the plug cover 2 and the plug pin 3. The docking component is used to dock the two rectangular connectors. The docking component includes a plurality of docking posts 81 and docking holes 82. A plurality of connecting posts 22 are provided below the plug cover 2, and a plurality of jacks 14 corresponding to each connecting post 22 are provided on the plug 1. A plurality of raised ribs 24 are provided on the outer side of each connecting post 22, so that the connecting post 22 and the jack 13 form an interference fit.

[0025] like Figure 1-Figure 3 , Figure 5 , Figure 6 As shown, the L-shaped pins 3 of the present invention include two forms: long pins and short pins. A plurality of L-shaped recesses 71 are provided on the pin mounting block 7. The PCB connection ends of the short pins are respectively provided in the L-shaped recesses 71. A plurality of notches 23 matching the surfaces of the PCB connection ends of the pins are provided on the lower edge of the plug cover 2. When the plug cover 2 is connected to the plug 1, the PCB connection ends of the short pins 3 are pressed into the L-shaped recesses 71 by the notches 23 on the lower edge of the plug cover 2. A plurality of notches 23 are symmetrically provided on the two lower edges of the plug cover 2.

[0026] A vertical slot 72 is provided at the other end of the pin mounting block 7, which is connected to a hole 73 provided at the bottom of the pin mounting block 7. The socket connection end of another long pin 3 is provided in the vertical slot 72, and the PCB connection end portion is provided in the hole 73 at the bottom of the mounting block. When the plug cover 2 is connected to the plug 1, each long pin 3 is fixed between the plug 1 and the plug cover 2.

[0027] like Figure 1 and Figure 4As shown, a protrusion 12 for preventing reverse insertion is provided on one side of the inner side of the plug 1, and a groove 11 cooperating with the protrusion 12 for preventing reverse insertion is provided on the surface of the socket 4 that cooperates with the side of the plug 1.

[0028] As a specific embodiment, the rectangular connector of the present invention is a 32-position rectangular connector, including 32 pins 3, which are divided into two rows, one row (16 pins) of short pins and one row (16 pins) of long pins arranged behind the row of short pins, and the lower ends of the long pins are located below the connection ends of the short pins and the PCB. When installing the pins, the short pins and the long pins can be respectively installed on the pin mounting block 7, and the plug 1 can be connected to the plug cover 2, or the long pins can be first set in the plug mounting block 1, and the short pins can be placed in the notch 23 set at the bottom of the plug cover 2, and then the plug socket 2 can be connected to the plug 1. Figure 7 As shown, when the 32-bit rectangular connector needs to be expanded to a 64-bit rectangular connector, the first rectangular connector is as follows Figure 1 During the assembly of the male head of another rectangular connector, after the pin 3 is assembled to the pin mounting block 7, the assembly consisting of the pin 3, the pin mounting block 7 and the plug 1 is horizontally rotated 180°, and the rest of the assembly process remains unchanged. The second rectangular connector thus obtained is horizontally rotated 180° and can be connected to the first rectangular connector through the docking column 81 and the docking hole 82, forming a 64-position male head. The outer frame 5 is selected to be an outer frame 5 that can accommodate two rectangular connectors at the same time, and the plug covers 2 of the two rectangular connectors are both accommodated therein, forming a 64-position connector. A PCB board is set between the two rectangular connectors, and each pin is welded to the PCB board respectively.

[0029] If you want to expand it to a 96-bit rectangular connector, you need to set docking posts 81 and docking holes 82 on both sides of the plug cover 2 of the second rectangular connector, repeat the assembly process of the second rectangular connector, and then connect the third rectangular connector to the second connector through the docking posts and docking holes. The female connector uses a standard straight-insert pin. The straight-insert pin in the female connector is used to connect with the pin 3 set in the male connector. After the incoming wire is fixed to the pin using a special tool, it can be directly inserted into the socket 4 and the pin hole 6; the end of the bent part of each pin 3 (that is, the part set on the pin mounting block) has a narrowed part, which can be welded on the PCB. If you need to expand it to a connector with more digits, just repeat the above process.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
