Description

Technical Field

[0001] This utility model relates to the field of DIP switch technology, specifically to an enhanced DIP switch. Background Technology

[0002] A DIP switch is a manually operated switch used for circuit on / off, address setting, or function selection, and is widely used in various electronic devices. In practical applications, due to uneven component heights or panel obstruction, it is often necessary to raise the overall height to facilitate toggle operation.

[0003] Currently, the common practice for raising the height of DIP switches is to use a separate IC adapter socket. This socket is first soldered to the circuit board, and then the standard DIP switch is inserted into the socket, using the height of the socket itself to achieve the desired elevation. However, this traditional method has significant drawbacks: First, the additional socket not only increases material procurement costs but also adds complexity to assembly processes and supply chain management; second, the use of flexible contact between the switch pins and the socket instead of direct soldering makes them susceptible to poor contact, increased resistance, and even signal interruption under mechanical vibration, environmental corrosion, or repeated insertion and removal, severely reducing connection reliability and long-term product stability; furthermore, adapter sockets typically occupy a large board area, which is detrimental to the high-density design of electronic products.

[0004] Therefore, existing technologies suffer from problems such as high cost, poor reliability, and low space utilization, and there is an urgent need for a highly integrated and reliable one-piece heightening solution to address these issues. Utility Model Content

[0005] The present invention provides a height-enhanced DIP switch to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A height-adjustable DIP switch includes a switch body and a terminal sleeve connected to the bottom of the switch body. The switch body includes a switch housing with a plurality of terminals extending from its interior to the bottom. Each terminal has an integrally extended pin for soldering at its bottom end. The terminal sleeve has a plurality of terminal holes for the pins to pass through. A groove is formed in the center of the bottom wall of the switch housing, and a boss that matches the groove is formed in the center of the top wall of the terminal sleeve. The boss fits into the groove to achieve precise alignment and connection between the switch body and the terminal sleeve. The terminal sleeve is used to increase the overall height of the DIP switch and provide lateral support for the vertical portion of the terminals.

[0008] Preferably, the terminal hole has a tapered structure that is wider at the top and narrower at the bottom.

[0009] Preferably, the cross-sectional shape of the groove and the boss is one of square, circular or elliptical.

[0010] Preferably, the boss and the groove are interference fit.

[0011] Beneficial effects

[0012] This utility model provides a height-enhanced DIP switch. Through the integrated design of the switch body and terminal sleeve, it achieves overall height enhancement while effectively improving structural stability and soldering reliability. Compared with the traditional solution using IC adapter sockets, this solution eliminates the need for a separate socket component, reducing material costs and assembly complexity, and avoiding connection problems caused by contact elasticity decay. The terminal sleeve not only serves to increase height but also provides lateral support for the extended terminals, preventing wobbling or deformation after soldering and ensuring the long-term stability of the switch in vibration environments. Furthermore, this structure saves circuit board layout space, supports high-density assembly, and can flexibly adapt to the installation height requirements of different devices, significantly improving the product's overall applicability and economy.

[0025] This embodiment provides a height-adjustable DIP switch, including a switch body 1 and a terminal sleeve 2 connected to its bottom. The switch body 1 includes a switch housing 11, from which a plurality of terminals 12 extend from the inside to the bottom. During production, the middle portion of the terminals 12 is lengthened to the required height, and each terminal 12 has an integrally extended lead 13 for soldering at its bottom end. The terminal sleeve 2 has a plurality of terminal holes 21 for the leads 13 to pass through. The terminal holes 21 have a tapered structure that is wider at the top and narrower at the bottom. This design helps to guide the leads to quick and accurate alignment during automated assembly, improving insertion efficiency.

[0026] To further improve alignment accuracy and connection stability, a groove 111 is formed in the center of the bottom wall of the switch housing 11, and a boss 22 with a matching shape is provided in the center of the top wall of the terminal sleeve 2. The boss 22 is embedded in the groove 111, realizing precise positioning and reliable connection between the switch body 1 and the terminal sleeve 2.
