Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Embodiment

[0029] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the utility model provides a connection component for automatically assembling a main board, which includes a plastic body 1. A metal shell is arranged outside the plastic body 1. A plurality of terminal slots 4 are arranged on the plastic body 1. In this embodiment, the terminal slots 4 are square slot structures separated from each other, and a partition 3 is arranged between adjacent terminal slots. The partition 3 protrudes from the metal shell, so that when the component is pressed on the PCB board, the partition 3 separates the metal shell from the PCB board to prevent short circuit. A jack 5 is arranged on the side wall of the terminal slot 4. The terminal 18 passes through the jack 5 and is located in the terminal slot 4, and the terminal 18 extending out of the terminal slot 4 is connected to the wire of the load 23 to be connected. The load can be a computer cooling fan or a speaker, etc., so as to ensure that the load 23 can be grabbed by an automatic manipulator when connected to the main board. The terminal 18 includes a first bending part 19 and a second bending part 20 arranged in parallel. A third bending part 21 is integrally formed on the second bending part 20. The third bending part 21 protrudes from the straight line where the first bending part 19 and the second bending part 20 are located and protrudes from the terminal slot 4. When pressed and contacted with the PCB board 22, the third bending part 21 is pressed on the exposed conductive metal of the PCB board 22 to achieve conduction, and the first bending part 19 and the second bending part 20 are deformed to ensure their tight combination. The setting of multiple groups of bending parts ensures that when the terminal has a large stroke deformation, the yield is reduced.

[0030] A metal shell is arranged outside the plastic body 1. As Figure 4 shown, in order to be able to assemble with the metal shell more accurately, at least two groups of positioning pins 12 are integrally formed on the plastic body 1. Corresponding positioning holes are arranged on the metal shell. During assembly, the positioning pins 12 are inserted into the positioning holes, and the positioning pins 12 can be inserted into the holes on the shell of the load 23, so as to improve the accuracy of assembly positioning during automatic assembly. For the square body 17, an opening 26 corresponding to the terminal slot 4 is arranged on the square body 17. A vertical part 13 is arranged on the upper side of the square body 17. A locking ear 16 is arranged on the vertical part 13. The vertical part 13 is pressed on the side surface of the plastic body 1. A positioning opening 14 is arranged on the vertical part 13. A barb 15 is arranged on the plastic body 1. The barb 15 is stuck in the positioning opening 14, which can ensure the positioning stability of the plastic body 1 in the metal shell. In addition, an indentation groove 28 is arranged on one side of the plastic body 1 corresponding to the end of the terminal slot 4. A shell folding edge 27 is arranged on the edge of the square body 17. The shell folding edge 27 is pressed into the indentation groove. The setting of the shell folding edge 27 can increase the strength of the metal shell 2. A locking nail passes through the locking ear 16, and the whole component is locked on the load 23 through the locking nail, which is convenient for automatic production lines to lock. After the device is connected and fixed to the load 23 (fan) through the connection component, it can be automatically grabbed by the automatic line and the screws can be locked, solving the problem that the original connection through flexible wires requires manual insertion.

[0031] In this embodiment, it should be noted that in order to determine the connection stability between the connection component and the PCB board 22, a positioning groove 6 is provided on the plastic body 1, and an identification device 7 passes through the positioning groove 6. As shown in Figure 6 , Figure 7 , the two ends of the identification device 7 respectively pass through the metal shells at the upper and lower positions of the plastic body 1, and one end presses on the PCB board 22 and can move in the positioning groove 6. When the connection component is inserted into the PCB board 22, the length of the identification device 7 extending out of the metal shell is used to determine whether the connection component is inserted into the PCB board 22 in place. Among them, the positioning groove 6 includes a middle hole body 8, and at least one limiting groove 9 is provided on the middle edge, and there is a hole groove corresponding to the middle hole body on the corresponding lower housing 2, but there is no hole position on the lower housing 2 corresponding to the limiting groove 9. The identification device 7 includes a telescopic body 10, and a clamping block 11 is provided on the side of the telescopic body 10. The telescopic body 10 is inserted into the middle hole body 8, and the clamping block 11 is inserted into the limiting groove 9. In this embodiment, the telescopic body 10 is set to be cylindrical, and of course, the specific shape of the telescopic body is not limited. The specific working principle of the identification device 7 is as follows: In the initial state, the clamping block 11 of the telescopic body 10 presses on the lower housing 2. At this time, one end of the telescopic body 10 extends out of the lower metal shell, and the other end is located in the middle hole body 8 and does not extend out. After the connection component is inserted into the PCB board 22, the connection part between the terminal 18 and the PCB board 22 is in contact. At the same time, the telescopic body 10 presses on the PCB board 22 and is pushed until the end is flush with the middle hole body 8, then it is determined that the insertion is in place and the connection is accurate.

[0032] Finally, in order to prevent the terminals from being worn when not in use, as shown in Figure 8 , a protective shell 24 is provided on one side of the terminal protruding from the plastic body. The protective shell includes a plate body, and clamping feet 25 are provided around the plate body. The plate body covers the upper part of the terminal and the clamping feet 25 are clamped outside the metal shell.
