Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a dual-contact sensor connector. Background Technology

[0002] In the field of modern electronic equipment manufacturing, sensor connectors are key components that connect sensors to circuit systems. Their installation and maintenance methods directly affect production efficiency, equipment reliability, and subsequent maintenance costs.

[0003] Traditional sensor connector mounting methods largely rely on soldering. During soldering, the connector pins or contacts are fused to corresponding solder points on the circuit board at high temperatures to ensure a stable electrical connection. However, soldering has several drawbacks. Firstly, it requires specialized equipment and skilled operators, and is subject to specific environmental conditions, increasing production complexity and cost. Secondly, soldering quality is easily affected by various factors, such as soldering temperature, time, and solder quality. Poor soldering, such as cold solder joints or short circuits, will lead to unstable electrical connections between the sensor and the circuit board, affecting the normal operation of the equipment. Furthermore, soldered connectors are difficult to disassemble. If a sensor malfunctions or needs upgrading or replacement, destructive disassembly is often required, potentially damaging the circuit board and increasing repair time and costs.

[0004] Furthermore, as electronic devices evolve towards miniaturization and high integration, higher demands are placed on the installation space and efficiency of sensor connectors. Traditional soldering installation methods are difficult to operate in confined spaces and cannot meet the needs of rapid and efficient production. Simultaneously, during equipment use, poor contact may occur between the sensor and connector due to prolonged use, vibration, environmental factors, etc., and traditional connector structures require complete replacement or complex repair operations during maintenance, increasing the difficulty and cost of maintenance. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a dual-contact sensor connector, which can effectively solve the problems mentioned in the background technology that traditional connector structures rely on welding processes during assembly and require overall replacement or complex maintenance operations during maintenance, which increases the difficulty and cost of maintenance.

The housing is provided with multiple placement parts, and each placement part is fitted with an end bullet piece. The end bullet pieces are arranged vertically and staggered within the placement part. The end bullet includes a bullet base, the lower end of which is bent forward to form a first bullet abutment portion for contacting the sensor, and the upper end is bent backward to form a second bullet abutment portion. An opening is provided below the placement part, and the second spring contact part passes through the opening and is electrically connected to the contact area of ​​the circuit board; The sensor is inserted into the slot and abuts against the first spring contact part.

[0007] Furthermore, the first spring contact portion has a Z-shaped structure.

[0008] Furthermore, the positioning posts are distributed diagonally.

[0009] Furthermore, the corner of the housing near the positioning post is provided with a chamfered surface.

[0010] Furthermore, the positioning post and the housing are integrally formed.

[0011] Furthermore, the slot opening is provided with a chamfered structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Solder-free rapid installation: The positioning pins and positioning holes work together to achieve mechanical positioning, and the spring contacts are directly pressed and connected to the PCB contact area, eliminating the need for traditional soldering processes, saving soldering steps, shortening assembly time, supporting rapid assembly by automated equipment, and improving assembly efficiency.

[0016] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0017] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0018] like Figure 1-4 As shown, this utility model provides a dual-contact sensor 3 connector, including a circuit board 1, a housing 2, an end bullet piece 5 and a sensor 3. The circuit board 1 is provided with a positioning hole 9 and a contact area 8. The housing 2 is located above the circuit board 1, with a positioning post 6 at the bottom that mates with the positioning hole 9, and a slot 7 that runs vertically through the middle. The housing 2 has multiple placement parts 4, and each placement part 4 has an end bullet piece 5 snapped into it. The end bullet pieces 5 are arranged vertically and staggered in the placement part 4. The end bullet piece 5 includes a bullet piece base 51, the lower end of which is bent forward to form a first bullet piece abutting part 52 for abutting against the sensor 3, and the upper end is bent backward to form a second bullet piece abutting part 53. An opening 10 is provided below the placement part 4, and the second spring contact part 53 passes through the opening 10 and is electrically connected to the contact area 8 of the circuit board 1. Sensor 3 is inserted into slot 7 and abuts against the first spring contact part 52.

[0019] Solder-free quick installation: The positioning post 6 and the positioning hole 9 cooperate to achieve mechanical positioning, and the spring contact area 8 is directly pressed and connected to the PCB. There is no need for traditional soldering process, which saves the soldering process, shortens the assembly time, supports rapid assembly of automated equipment, and improves assembly efficiency.

[0020] Ease of maintenance: Sensor 3 can be disassembled and replaced without damage; if there is poor contact, only the spring assembly needs to be replaced.

[0021] See Figure 4The first spring contact part 52 has a Z-shaped structure to guide the insertion of the sensor 3. The Z-shaped structure has a certain guiding function. When the sensor 3 is inserted into the placement part 4 of the connector, this Z-shaped structure can first contact the end of the sensor 3 and guide the sensor 3 to be inserted smoothly in the correct direction, avoiding collision or jamming between the sensor 3 and the end spring contact 5 due to insertion direction deviation, thus improving the efficiency and accuracy of installation.

[0022] See Figure 2 The positioning posts 6 are arranged diagonally, and the corner of the housing 2 near the positioning posts 6 is provided with a chamfered surface 11. The foolproof and error-proof structure features vertically staggered spring contacts forming a specific contact sequence, a longitudinally penetrating slot 7 to ensure the insertion direction of the sensor 3, and a chamfered edge on the housing 2 for auxiliary guidance.

[0023] See Figure 2 The positioning post 6 and the housing 2 are integrally molded. The integral molding design realizes the dual functions of mechanical positioning and structural reinforcement, thereby improving the assembly accuracy and overall reliability of the connector.

[0024] See Figure 1 The slot 7 opening 10 is provided with a chamfer structure. The chamfer structure can reduce the resistance encountered by the sensor 3 when it is inserted into the slot 7, making the assembly process smoother. The chamfer structure can also play a guiding and positioning role, helping the sensor 3 to enter the slot 7 more accurately, improving the accuracy and efficiency of assembly.

[0025] During use, the dual-contact design means that one end of the spring contacts the sensor 3 and the other end contacts the PCB board. Customers do not need to solder the spring; they can simply assemble it onto the PCB board for use, which greatly simplifies the use of the connector.
