Description

Technical Field

[0001] This utility model relates to the field of keyboard button technology, and in particular to an electronic assembly connection structure for a button switch. Background Technology

[0002] The existing patent for Hall element magnetic shaft keyboard key switch, patent number 2024223061297, discloses a connection structure between the electronic assembly and the base. In this structure, the connecting terminal is first inserted into the through hole of the base, then the built-in circuit board is connected to the connecting terminal, and finally the connecting terminal and the built-in circuit board are electrically connected by soldering. At the same time, in order to ensure the stability of the connecting terminal, the base is required to have a certain thickness (the part where the connected terminal is inserted). This structure results in the Hall switch on the built-in circuit board being relatively far from the bottom of the base, making it difficult to place the Hall switch closer to the bottom of the base. Utility Model Content

[0003] In view of the shortcomings in the background technology, the present invention provides an electronic assembly connection structure for a push-button switch, and overcomes the above-mentioned defects.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an electronic assembly connection structure for a push button switch, including a base, a circuit board, a connection terminal, an auxiliary block, and a Hall element disposed on the circuit board. The connection terminal includes a fixed end and a connecting end. The fixed end is connected to the auxiliary block through a fixed auxiliary part, and the connecting end passes through the circuit board and the base in sequence.

[0005] The upper end of the fixing part is provided with barbs, and the lower end of the fixing part extends with a fixing terminal. The fixing part and the connecting terminal are integrally formed.

[0006] An angle is provided between the fixed auxiliary part and the connecting terminal.

[0007] The circuit board is provided with a hole one and a hole two (or slot) for inserting a connecting end and a fixed terminal. The fixed terminal is inserted into the hole one, and the connecting end passes through the hole two (or slot).

[0008] The fixed terminal is fixedly connected to the hole by soldering.

[0009] The auxiliary block is provided with a clearance groove, which corresponds to the Hall element.

[0010] The auxiliary block is provided with a limiting protrusion, and the base is provided with a limiting groove corresponding to the limiting protrusion. Ribs are provided on the surface of the base that contacts the auxiliary block.

[0011] By adopting the above technical solution, the problem of the Hall element in the existing magnetic axis keyboard key switch being difficult to place closer to the bottom of the base is effectively improved. By using an auxiliary block as a fixing device for the connection terminal, the auxiliary block with a certain thickness provides stability to the connection terminal. The connection end of the connection terminal passes through the base, and the Hall element is placed close to the bottom of the base while ensuring that the connection terminal is stably fixed.

[0017] refer to Figure 1-5 It is understood that the present invention discloses an electronic assembly connection structure for a push button switch, including a base 1, a circuit board 2, a connection terminal 3, an auxiliary block 4, and a Hall element 5 disposed on the circuit board 2. The connection terminal 3 includes a fixed end 31 and a connection end 32. The fixed end 31 is connected to the auxiliary block 4 through a fixed auxiliary part 6, and the connection end 32 passes through the circuit board 2 and the base 1 in sequence.

[0018] The upper end of the fixing auxiliary part 6 is provided with barbs 61, and the lower end of the fixing auxiliary part 6 extends with a fixing terminal 62. The fixing auxiliary part 6 and the connecting terminal 3 are integrally formed, as shown in the attached figure. Figure 5 As shown, the barbs 61 help to securely fix the auxiliary part 6 and the slot 41 together. The auxiliary block 4 is made of plastic.

[0019] An angle is provided between the fixing auxiliary part 6 and the connecting terminal 3, as shown in the attached figure. Figure 5 As shown, preferably, the fixing auxiliary part 6 is set at a 90-degree angle to the connecting terminal 3.

[0020] The circuit board 2 is provided with a first hole 21 and a second hole (or slot) 22 for inserting a connecting end 32 and a fixing terminal 62. The fixing terminal 62 is inserted into the first hole 21, and the connecting end 32 passes through the second hole (or slot) 22, as shown in the attached diagram. Figure 3-4As shown, the fixed terminal 62 is inserted into hole 21, and the fixed terminal 62 and hole 21 are firmly connected by soldering to ensure that the connecting terminal 3 and the circuit board 2 are effectively connected.

[0021] The auxiliary block 4 is provided with a slot 41 and a clearance groove 42. The clearance groove 42 corresponds to the Hall element 5. The shape of the slot 41 corresponds to the cross-sectional shape of the connecting terminal 3 and the fixing auxiliary part 6. The fixing end 31 of the connecting terminal 3 and the fixing auxiliary part 6 are inserted into the slot 41, as shown in the attached figure. Figure 3 Appendix Figure 5 As shown.

[0022] The auxiliary block 4 is provided with a limiting protrusion 43, and the base 1 is provided with a limiting groove 11 corresponding to the limiting protrusion 43. Ribs 12 are provided on the surface of the base 1 that contacts the auxiliary block 4, as shown in the attached figure. Figure 2 As shown, this makes the connection between the auxiliary block 4 and the base 1 more secure and enhances stability.

[0023] Specifically, as shown in the attached document Figure 5 As shown, the fixed end 31 of the connecting terminal 3 and the fixed auxiliary part 6 are inserted into the slot 41. Due to the influence of the barbs 61, the connection between the connecting terminal 3 and the auxiliary block 4 is relatively firm; combined with the attached... Figure 4 As shown, the connecting end 32 passes through the circuit board 2, and the fixing terminal 62 is inserted into hole 21 of the circuit board 2. Hole 21 is a circuit board connection hole, and the two are connected by solder to achieve conductivity; as shown in the attached figure. Figure 2 As shown, the assembled electronic assembly is placed inside the base 1, that is, the connecting end 32 of the connecting terminal 3 passes through the base 1, and finally as shown in the attached figure. Figure 1 As shown in the diagram. The Hall element 5, thus positioned on the circuit board 2, is located near the bottom of the base 1.

By using the auxiliary block 4 as a fixing device for the connecting terminal 3, the auxiliary block 4 with a certain thickness provides a firm fixation for the connecting terminal 3. The connecting end 32 of the connecting terminal 3 passes through the base 1. Under the premise of ensuring that the connecting terminal 3 is stably fixed, the Hall element 5 is placed close to the bottom of the base 1.
