Description

Technical Field

[0001] This utility model relates to the field of DIP switch technology, specifically to a novel right-angle terminal DIP switch. Background Technology

[0002] DIP switches are key components on circuit boards (PCBs) used to configure circuit functions. Right-angled DIP switches are widely used because they save vertical space. Currently, this type of switch is generally manufactured using a long lead design to accommodate different board thicknesses and soldering processes. The leads need to be bent at 90 degrees before assembly.

[0003] However, this conventional design has a significant drawback: the bent terminals suffer from stress concentration and a lack of effective reinforcement, resulting in a significant decrease in mechanical strength and insufficient robustness. This makes the pins highly susceptible to bending, twisting, and other deformations during subsequent mounting, insertion, and transportation, leading to problems such as poor coplanarity, misalignment, and insertion difficulties. This not only causes low efficiency in automated mounting but may also result in poor soldering, short circuits, and other soldering defects, severely impacting production yield and product reliability.

[0004] With the miniaturization of electronic devices and the increasing automation of production, the market urgently needs a right-angle terminal DIP switch with a robust pin structure and strong resistance to deformation in order to improve production efficiency and the quality stability of end products. Utility Model Content

[0005] The present invention provides a novel right-angle terminal 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 novel right-angle terminal DIP switch includes a switch base and a terminal block connected to the switch base. The switch base has several stationary terminals at its rear bottom and several moving terminals at its rear top, with a slot in the center of the rear wall. The terminal block has a locking platform on one end face near the switch base that mates with the slot, and several terminal slots on the other end face away from the switch base. The top and bottom of the terminal block have several moving terminal holes and stationary terminal holes that communicate with the terminal slots. The stationary terminals pass through the corresponding stationary terminal holes and bend downwards, and their sides are engaged and fixed to the side wall of the terminal slot by locking teeth. The moving terminals pass through the corresponding moving terminal holes and bend downwards, and their sides are engaged and fixed to the side wall of the terminal slot by latches.

[0008] Preferably, the retaining teeth of the stationary terminal are engaged with the bottom of the two side walls of the terminal slot.

[0009] Preferably, the buckle is a protruding structure provided on both sides of the terminal slot, and both sides of the moving terminal are respectively engaged with the buckle.

[0010] Preferably, the stationary terminal hole is located at the bottom of the terminal block, and the moving terminal hole is located at the top of the terminal block.

[0011] Preferably, the card platform and the card slot are fitted with an interference fit.

[0012] Preferably, the number of terminal slots is equal to the number of stationary terminals and moving terminals, and each terminal slot accommodates one stationary terminal and one moving terminal.

[0013] Beneficial effects

[0014] This utility model of a right-angle terminal DIP switch effectively solves the industry pain point of easy pin deformation in traditional products through innovative structural design. Its core lies in the addition of an independent terminal block, which is tightly connected to the switch body through an interference fit between the locking platform and the locking slot, forming a stable support. The bent stationary terminal is locked to the bottom of the terminal slot by locking teeth, while the moving terminal is locked to the side wall of the terminal slot, achieving precise and rigid fixation of each pin.

[0015] This structure significantly enhances the mechanical strength and torsional resistance of the bends and the overall pin configuration, ensuring pin coplanarity and alignment, and preventing bending deformation during subsequent mounting and insertion processes. This substantially improves the insertion efficiency and soldering yield of automated production, fundamentally reducing scrap and production interruptions caused by pin issues, and guaranteeing end-product quality and production efficiency.

[0027] like Figure 1-4 The diagram shown is a structural schematic of a novel right-angle terminal DIP switch according to a preferred embodiment of the present invention.

[0028] In this embodiment, a switch base 1 and a terminal block 2 connected to the switch base 1 are included. The bottom rear of the switch base 1 has several stationary terminals 11, the top rear has several moving terminals 12, and a slot 13 is formed in the center of the rear wall. The terminal block 2 has a locking platform 21 on one end face near the switch base 1 that mates with the slot 13, and several terminal slots 22 on the other end face away from the switch base 1. A tight connection between the terminal block 2 and the switch base 1 is achieved through an interference fit where the locking platform 21 is inserted into the slot 13. The top and bottom of the terminal block 2 are respectively... A plurality of moving terminal holes 23 and stationary terminal holes 24 communicating with the terminal slot 22 are provided; the stationary terminal 11 passes through the corresponding stationary terminal hole 24 and bends downward, and its two sides are engaged and fixed with the side wall of the terminal slot 22 by the locking teeth 111; the moving terminal 12 passes through the corresponding moving terminal hole 23 and bends downward, and its two sides are engaged and fixed with the buckles 221 provided on the side wall of the terminal slot 22. The moving terminal 12 and the stationary terminal 11 are stably supported by the terminal seat 2, which greatly enhances the mechanical strength and torsional resistance of the moving terminal 12 and the stationary terminal 11.

[0029] In this embodiment, the retaining teeth 111 of the stationary terminal 11 are engaged with the bottom of the two side walls of the terminal slot 22, and this structure achieves the fixation and support of the stationary terminal 11.

[0030] In this embodiment, the buckle 221 is a protruding structure provided on both sides of the terminal slot 22. Both sides of the moving terminal 12 are respectively engaged with the buckle 221. This structure realizes the fixation of the moving terminal 12.

[0031] In this embodiment, the stationary terminal hole 24 is located at the bottom of the terminal base 2, and the moving terminal hole 23 is located at the top of the terminal base 2. The number of stationary terminal holes 24 is the same as that of stationary terminal 11, and the number of moving terminal holes 23 is the same as that of moving terminal 12.

[0032] In this embodiment, the card holder 21 and the card slot 13 are fitted with an interference fit, which makes the card holder 21 and the card slot 13 fit more tightly, thereby making the terminal block 2 and the switch block 1 more firmly fixed.

[0033] In this embodiment, the number of terminal slots 22 is equal to the number of stationary terminals 11 and moving terminals 12, and each terminal slot 22 accommodates one stationary terminal 11 and one moving terminal 12.
