Embodiment
[0025] As Figures 1-5 shown, the present utility model provides a compact connector, which includes a housing 2 and a cover 3 arranged on the upper side of the housing 2. The housing 2 is provided with a placement portion 6 for accommodating a sensor 4. Two rows of terminal spring pieces 5 are fixedly connected in the placement portion 6 by in-mold forming. The terminal spring pieces 5 are arranged staggered to divide the placement portion 6 into several cavities. A plurality of positioning posts 7 for clamping the sensor are fixedly connected staggered on the lower surface of the cover 3. When the cover 3 and the housing 2 are assembled, the positioning posts 7 just insert into the cavities. The positioning posts 7 on the cover 3 clamp the sensor 4, playing a positioning role for the sensor 4 and solving the problem of difficult assembly due to the soft material of the sensor 4;
[0026] The housing 2 is provided with slots 8 that are arranged on the opposite sides of the housing 2 and are in cooperation with the sensor 4 and open upward.
[0027] The placement portion 6 is divided into several cavities by the staggered terminal spring pieces 5. This design effectively utilizes the space inside the housing 2 and also makes the whole connector structure more compact.
[0028] The positioning posts 7 fixedly connected staggered on the lower surface of the cover 3 match the cavities in the housing 2. When the cover 3 and the housing 2 are assembled, the positioning posts 7 can accurately insert into the cavities, thus achieving a stable connection and accurate positioning. This design improves the assembly efficiency of the connector and also ensures the connection stability and reliability between components.
[0029] The terminal spring pieces 5 are fixed in the housing 2 by in-mold forming technology. This fixing method enhances the connection strength between the terminal spring pieces 5 and the housing 2, and also enables the whole connector to maintain good stability when subjected to external impact or vibration, and can effectively extend the service life of the device.
[0030] The opening of slot 8 enables the sensor 4 to be precisely inserted into the predetermined position, ensuring the correct docking of the sensor 4 with the internal structure of the connector, with high precision and tightness, and can ensure that the sensor 4 is not easily loosened or detached during operation, thus guaranteeing the stability of the connection.
[0031] See Figure 2 、 Figure 4 and Figure 5 , the terminal spring piece 5 is a "Z"-shaped metal spring piece, and the bent ends of the terminal spring piece 5 are all arranged towards the inside, and the bent ends are clamped with the pins of the sensor 4.
[0032] The bent ends of the "Z"-shaped metal spring piece are arranged towards the inside, which can precisely align and clamp the pins of the sensor 4, ensuring a stable connection between the sensor 4 and the connector, and preventing the sensor 4 from loosening or detaching during operation.
[0033] The clamping method of the bent ends provides physical support and also enhances the stability of the connection through the elastic force of the metal spring piece. Even when subjected to external shocks or vibrations, the connection stability can be maintained.
[0034] The design of the "Z"-shaped metal spring piece makes the installation process of the sensor 4 simpler and faster. Just align the pins of the sensor 4 and insert them into the bent ends of the spring piece to complete the assembly.
[0035] When the sensor 4 needs to be replaced, just gently pull out the pin to remove the sensor 4 from the connector, without disassembling the whole connector, reducing the complexity and cost of maintenance.
[0036] See Figures 2 to 5 , the number of positioning posts 7 is the same as the number of terminal spring pieces 5.
[0037] Since the number of positioning posts 7 is the same as the number of terminal spring pieces 5, each positioning post 7 can precisely correspond to a terminal spring piece 5, thus ensuring the position accuracy of the terminal spring piece 5 during assembly or processing.
[0038] The positioning posts 7 clamp the sensor 4 through their staggered arrangement structure, providing a stable positioning reference for the terminal spring pieces 5. During assembly or processing, the terminal spring pieces 5 can be combined with the positioning posts 7 at the predetermined positions, thus maintaining their stability and accuracy.
[0039] See Figure 3 , the positioning posts 7 and the machine cover 3 are of an integrally formed structure.
[0040] The integrally formed structure makes there be no additional connecting parts or interfaces between the positioning posts 7 and the machine cover 3, thereby enhancing the stability of the overall structure and being able to reduce the loosening or damage of components caused by vibration or impact.
[0041] The integrally formed structure ensures the precise matching between the positioning post 7 and the machine cover 3, and also reduces the gap problems caused by connecting parts or interfaces, thus avoiding the possibility of impurities such as dust and moisture entering the interior of the device.
[0042] See Figure 3 , a chamfer structure is provided at the end of the positioning post 7.
[0043] The chamfer structure makes the end of the positioning post 7 form an inclined surface. When the positioning post 7 is assembled with the housing 2, the inclined surface can guide the positioning post 7 to enter the assembly position more easily, reducing the resistance and friction during the assembly process.
[0044] See Figure 2 , Figure 4 and Figure 5 , a chamfer structure is provided at the opening of the slot 8.
[0045] The chamfer structure can reduce the resistance encountered by the sensor 4 when inserted into the slot 8, making the assembly process smoother. The chamfer structure can also play a role in guiding and positioning, helping the sensor 4 to enter the slot 8 more accurately, improving the accuracy and efficiency of the assembly.
[0046] See Figure 1 and Figure 2 , the lower surface of the housing 2 is connected with a circuit board 1, and the part of the terminal spring piece 5 extending out of the housing 2 is welded to the circuit board 1.
[0047] The welded connection ensures a firm and reliable electrical connection between the circuit board 1 and the terminal spring piece 5, guaranteeing the stable transmission of electrical signals.
[0048] The circuit board 1 is fixed on the lower surface of the housing 2 through the welded connection, providing structural support for the circuit board 1 and also ensuring the stability and position accuracy of the circuit board 1 inside the housing 2.
