Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electronics, and particularly relates to an electronic device. Background Art
[0002] The connection mode between the positive conductive part and the negative conductive part of the existing electronic device and the circuit board is welding. Since the welding method is adopted, it is not conducive to assembly and the assembly time is long.
[0003] Especially for wireless mice, during the assembly process, welding will lead to a complex assembly process. For existing wireless mice using dry batteries, the dry batteries are required to supply power to the circuit board. This requires the positive and negative conductive parts of the battery to be fixed at both ends of the battery compartment. The dry battery is installed in the battery compartment, the positive electrode of the battery contacts the positive conductive part, and the negative electrode of the battery contacts the negative conductive part. The positive electrode of the dry battery needs to be connected to the positive input point on the circuit board, and the negative electrode of the dry battery needs to be connected to the negative input point on the circuit board. The existing methods are as follows:
[0004] 1. As shown in Figure 1 , two wires are used. One end of the positive wire is welded to the positive conductive part fixed in the battery compartment, and the other end is welded to the positive point on the circuit board. One end of the negative wire is welded to the negative conductive part fixed in the battery compartment, and the other end is welded to the negative point on the circuit board. Then, the circuit board is fixed into the lower cover, and screws are used to fix the circuit board to the lower cover.
[0005] 2. As shown in Figure 2 , two wires are used. One end of each of the two wires is respectively welded to the positive conductive part and the negative conductive part fixed in the battery compartment, and the other two ends of the two wires are respectively welded to a plastic housing with terminals. The plastic housing with terminals is then inserted into a pin socket welded on the circuit board. Then, the circuit board is fixed into the lower cover, and screws are used to fix the circuit board to the lower cover.
[0006] 3. As shown in Figure 3 , the positive conductive part and the negative conductive part are welded to the circuit board, and then the circuit board is fixed to the lower cover. The positive conductive part and the negative conductive part are simultaneously installed in the battery compartment. Then, screws are used to fix the circuit board to the lower cover.
[0007] Currently, when assembling the circuit board and the conductive part of an electronic device, the connection between the conductive part and the circuit board is first performed, and then the circuit board is assembled into the housing. There is no positioning between the conductive part, the circuit board, and the housing, and higher assembly skills are required to ensure accurate assembly positions, resulting in low assembly efficiency. And the current assembly requires welding the circuit board and the conductive part, which not only has many assembly processes but also makes it difficult to achieve automated assembly.

[0053] Embodiment 1:
[0054] AsFigures 4 to 12 As shown, an electronic device provided in this embodiment is a wireless mouse. It includes a housing 9, a circuit board 1, a positive conductive member 5, a negative conductive member 6, and a fastener disposed within the housing 9. The circuit board 1 has a positive contact position 2 and a negative contact position 3. The positive conductive member 5 has a first contact arm 7 electrically connected to the positive contact position 2. The first contact arm 7 is in close contact with the positive contact position 2 and is located below the positive contact position 2. The negative conductive member 6 has a second contact arm 8 electrically connected to the negative contact position 3. The second contact arm 8 is in close contact with the negative contact position 3 and is located below the negative contact position 3.
[0055] Both the first contact arm 7 and the second contact arm 8 have a first positioning hole 11 for mating with the housing 9. Through the setting of the first positioning hole 11 that mates with the housing 9, the assembly is positioned to ensure precise installation between the circuit board 1, the positive conductive member 5, the negative conductive member 6, and the housing 9. At the same time, it ensures precise alignment between the first contact arm 7 and the positive contact position 2, and between the second contact arm 8 and the negative contact position 3, ensuring stable electrical connection.
[0056] The fastener in this embodiment is a screw 15. The first contact arm 7 and the circuit board 1 are pressed against the inner bottom wall of the housing 9 by the screw 15 so that the first contact arm 7 is in close contact with the positive contact position 2. The second contact arm 8 and the circuit board 1 are pressed against the inner bottom wall of the housing 9 by the screw 15 so that the second contact arm 8 is in close contact with the negative contact position 3. In other embodiments, the way of pressing with the screw 15 can also be changed to a way of mutual clamping to achieve close contact. There is a space for installing a battery between the positive conductive member 5 and the negative conductive member 6. By using the way of close contact to achieve the circuit conduction between the circuit board 1, the positive conductive member 5, and the negative conductive member 6, welding is not required, which simplifies the structure and assembly process, shortens the assembly time, improves productivity, and provides a basis for automated assembly. In this embodiment, the fastener is pressed to ensure the close contact between the first contact arm and the positive contact position, and between the second contact arm and the negative contact position. Through the cooperation of the housing 9 and the fastener, the circuit board 1, the positive conductive member 5, and the negative conductive member 6 are clamped between the housing 9 and the fastener, not only assembling the circuit board 1, the positive conductive member 5, and the negative conductive member 6 into the housing 9, but also ensuring the stability of the circuit conduction between the positive conductive member 5, the negative conductive member 6, and the circuit board 1. Through the design of arranging the positive contact position 2 and the first contact arm 7 vertically, and the negative contact position 3 and the second contact arm 8 vertically, the assembly path is the same. Cooperating with the fastener, it can synchronously assemble the circuit board 1, the positive conductive member 5, and the negative conductive member 6 to the required positions. The positive contact position 2 and the negative contact position 3 in this embodiment are both solder pads. In other embodiments, it can also be a structure that can achieve the conduction between the circuit board 1, the first contact arm 7, and the second contact arm 8.
[0057] Specifically, the inner bottom wall of the housing 9 has two first positioning posts 10. The first positioning posts 10 pass through the first positioning holes 11. The circuit board 1 has two second positioning holes 12, and the first positioning posts 10 pass through the second positioning holes 12. Through the cooperation of the first positioning posts 10 with the first positioning holes 11 and the second positioning holes 12, the positioning and assembly of the positive electrode conductive member 5, the negative electrode conductive member 6, and the circuit board 1 are realized, ensuring the accurate alignment of the first contact arm 7 with the positive electrode contact position 2 and the second contact arm 8 with the negative electrode contact position 3, and ensuring stable electrical connection.
[0058] Among them, the inner bottom wall of the housing 9 also has two second positioning posts 13. Both the first contact arm 7 and the second contact arm 8 also have third positioning holes 14, and the second positioning posts 13 pass through the third positioning holes 14. Through the cooperation of the second positioning posts 13 with the third positioning holes 14, the positioning and assembly of the positive electrode conductive member 5 and the negative electrode conductive member 6 are further improved, avoiding the position deviation of the positive electrode conductive member 5 and the negative electrode conductive member 6, and ensuring the assembly accuracy.
[0059] Among them, a threaded groove 16 is formed in the first positioning post 10. The screw 15 is inserted into the threaded groove 16 and screwed with the threaded groove 16. When tightened, the nut of the screw 15 presses against the top wall of the circuit board 1, pressing the circuit board 1, the positive electrode conductive member 5, and the negative electrode conductive member 6 against the housing 9. During assembly, first, the positive electrode conductive member 5 and the negative electrode conductive member 6 are respectively sleeved on the two first positioning posts 10, and then the circuit board 1 is sleeved on the first positioning posts 10. At this time, the positive electrode conductive member 5 and the negative electrode conductive member 6 are clamped between the inner bottom wall of the housing 9 and the circuit board 1. Finally, the screw 15 is aligned with the threaded groove 16 and the screw 15 is tightened. By pressing the top wall of the circuit board 1 with the nut of the screw 15, not only the steps of assembling the circuit board 1, the positive electrode conductive member 5, and the negative electrode conductive member 6 on the housing 9 are completed, but also the pressing steps of the circuit board 1 with the positive electrode conductive member 5 and the negative electrode conductive member 6 are completed, ensuring the circuit conduction and greatly reducing the assembly process and assembly time.
[0060] Among them, the positive electrode conductive member 5 further includes a first bent arm 19 and a convex portion 20. One end of the first contact arm 7 is connected with a first bent arm 19, and one side of the first bent arm 19 has a convex portion 20. The negative electrode conductive member 6 further includes a second bent arm 21 and a spring 22. One end of the second contact arm 8 is connected with a second bent arm 21, and one side of the second bent arm 21 has a spring 22. The convex portion 20 is used to contact the positive electrode of the battery, and the spring 22 is used to contact the negative electrode of the battery.
[0061] Among them, the housing 9 has a battery compartment 23 for accommodating a battery. Both ends of the battery compartment 23 in the length direction have clamping positions 24, and the first bending arm 19 and the second bending arm 21 are respectively clamped to the two clamping positions 24. Through the arrangement of the clamping positions 24, in cooperation with the first positioning post 10 and the second positioning post 13, the positioning and assembly of the positive electrode conductive member 5 and the negative electrode conductive member 6 are realized, the positive electrode conductive member 5 and the negative electrode conductive member 6 are limited from different positions, and the assembly accuracy is high.
[0062] Among them, both the first bending arm 19 and the second bending arm 21 have elastic clamping blocks 4, and the elastic clamping blocks 4 cooperate with the clamping positions 24. Through the cooperation of the elastic clamping blocks 4 and the clamping positions 24, the stability after the assembly of the positive electrode conductive member 5 and the negative electrode conductive member 6 is further improved, and the effective connection between the battery and the positive electrode conductive member 5 and the negative electrode conductive member 6 is ensured.
[0063] Embodiment Two:
[0064] As Figures 13 to 16 shown, the difference between this embodiment and Embodiment One is that:
[0065] The fastener includes a screw 15 and a pressing block 17. A threaded groove 16 is opened in the first positioning post 10, a through hole 18 is opened in the pressing block 17, the screw 15 passes through the through hole 18 and is inserted into the threaded groove 16 and screwed with the threaded groove 16. When locked, the nut of the screw 15 presses the pressing block 17, and the top wall of the circuit board 1 is pressed by the pressing block 17, and the circuit board 1, the positive electrode conductive member 5, and the negative electrode conductive member 6 are pressed against the housing 9. Compared with Embodiment Two, in this embodiment, through the arrangement of the pressing block 17, the way that the nut of the screw 15 directly presses the circuit board 1 is changed to the way that the nut of the screw 15 acts on the pressing block 17, and then the circuit board 1 is pressed by the pressing block 17, avoiding the damage to the circuit board 1 caused by the direct locking of the screw 15, and at the same time avoiding the damage to the circuit board 1 caused by the rust of the screw 15.
