a second PCB disposed on the other end of the second stair-shaped pins and clamping slots, wherein the second PCB is connected to the first PCB by using connectors such that components of the second PCB are arranged by maximizing use of space,
wherein the clamping slots are in one-to-one correspondence with the second row of slots and are further disposed on a rear of the plug body,
wherein the clamping slots are configured to correct a position deviation of the second pin, and
wherein the clamping slots are positioned between the first PCB and the second PCB.
2. The plug according to claim 1 , wherein the plug comprises an on-board diagnostics II (OBD II) plug, wherein the first pins comprise eight pins, and wherein the second pins comprise eight pins.
3. The plug according to claim 1 , wherein the first pins comprise one bend, wherein the second pins comprise two bends, and wherein the first row of slots and the second row of slots are different rows and are parallel.
4. The plug according to claim 1 , wherein the first pins and the second pins comprise a same number of pins, wherein all of the first pins have a same L-shape, and wherein all of the second pins have a same stair-shape.
5. A printed circuit board (PCB) assembly, comprising:
a plug;
a first PCB, wherein the first PCB is configured to connect to one end of a first pin of the plug and connect to one end of a second pin of the plug, wherein the plug comprises a plug body, first pins, and second pins, wherein a first row of slots and a second row of slots are disposed on a rear of the plug body, and the first row and the second row are parallel, wherein the first pins are in one-to-one correspondence with the first row of slots and the second pins are in one-to-one correspondence with the second row of slots, wherein each of the first pins is L-shaped, one end of the first pin is embedded in a slot, in a corresponding position, of the first row of slots, and the other end is stair-shaped and is configured to connect to a first PCB, and wherein each of the second pins is stair-shaped, one end of the second pin is embedded in a slot, in a corresponding position, of the second row of slots, and the other end is configured to connect to the first PCB, is parallel to the end, which is connected to the first PCB, of the first pin, and is located on an outer side of the end, which is connected to the first PCB, of the first pin; and
a second PCB, wherein the second PCB is connected to the first PCB by using connectors, and wherein the second PCB is disposed on the other end of the second stair-shaped pin and clamping slots such that components of the second PCB are arranged by maximizing use of space,
wherein the clamping slots are in one-to-one correspondence with the second row of slots and are further disposed on a rear of the plug body,
wherein the clamping slots are configured to correct a position deviation of the second pin, and
wherein the clamping slots are positioned between the first PCB and the second PCB.
6. The PCB assembly according to claim 5 , wherein one end of the second PCB is adjacent to a plug body of the plug.
7. The PCB assembly according to claim 5 , wherein the plug comprises an on-board diagnostics II (OBD II) plug, wherein the first pins comprise eight pins, and wherein the second pins comprise eight pins.
8. The PCB assembly according to claim 5 , wherein the first pins comprise one bend, wherein the second pins comprise two bends, and wherein the first row of slots and the second row of slots are different rows and are parallel.
