Description

Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a sensor connector with a shielding structure. Background Technology

[0002] Currently, sensors are typically soldered to circuit boards using gold or aluminum wire bonding. However, this soldering method is often unreliable, leading to problems such as incomplete soldering, cracks, porosity, and slag inclusions. If the sensor needs to transmit a large number of signals, many more wires need to be bonded to the circuit board, complicating the structure, increasing manufacturing requirements, and raising costs. Since the circuit board is soldered to the side of the sensor, it occupies more space, necessitating a sealed connector design.

[0003] Hermetically sealed connector systems include adaptive seals between mating connector bodies to prevent environmental contaminants such as dust, dirt, water, or other fluids from entering the connector bodies. These adaptive seals also reduce relative movement between the connector bodies, and consequently, relative movement between the electrical terminals within the connector bodies caused by vibrations within the vehicle. Such relative movement between terminals can result in undesirable intermittent connections or contact corrosion. Unsealed connection systems lack adaptive seals and typically rely on connector mating / clearance to reduce movement between connector bodies, generally only functioning in low-vibration environments.

[0004] Therefore, it is necessary to invent a sensor connector with a shielding structure to solve the above problems. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6The sensor connector with a shielded structure shown includes a male terminal 1 and a female terminal 101, which mate with each other. A reinforcing connection mechanism 2 is provided inside the male terminal 1. The reinforcing connection mechanism 2 includes an extension post 201 fixedly connected to the end of the male terminal 1 away from the female terminal 101. A first insertion slot 204 is formed inside the male terminal 1. A reinforcing block 207 is inserted into the extension post 201. A sealing gasket 208 is fixedly connected to the outer wall of the reinforcing block 207 and is fixedly connected to the inside of the extension post 201. Two sets of terminal slots 209 are formed inside the reinforcing block 207. A third insertion slot is formed inside the female terminal 101. 206. The third insertion slot 206 and the first insertion block 202 are interlocked. The female terminal 101 has a second insertion slot 205 on both sides. The second insertion slot 205 is interlocked with the second insertion block 203. The second insertion block 203 is fixedly connected to the extension post 201. The overall strength of the male terminal 1 and the female terminal 101 is enhanced by the interlocking of the first insertion block 202 with the third insertion slot 206, the second insertion block 203 with the second insertion slot 205, and the first insertion slot 204 with the female terminal 101. The inner wall of the female terminal 101 is fixedly connected to the shielding mechanism 3. The third insertion slot 206 is opened inside the shielding mechanism 3. The bottom wall of the shielding mechanism 3 is fixedly connected to the compression block. 4. The pressing block 4 cooperates with the movement of subsequent parts. The bottom end of the first insertion block 202 has a bottom groove 5. A connecting rod 6 is hinged inside the bottom groove 5. A contact head 7 is fixedly connected to the top of the connecting rod 6. The contact head 7 is moved by the cooperation of the pressing block 4 and the connecting rod 6. The first insertion block 202 has a movable cavity 8 inside, and the movable cavity 8 communicates with the terminal groove 209. The top of the contact head 7 is located inside the movable cavity 8. The contact head 7 contacts the subsequent parts through the movable cavity 8. A fixing block 9 is fixedly connected to the inner side wall of the movable cavity 8, and an elastic block 10 is fixedly connected to the bottom end of the fixing block 9. The bottom end of the elastic block 10 abuts against a lifting block 11. The lifting block 11 is slidably connected to the movable cavity. Inside the connector 8, a pressing head is fixedly connected to the top of the lifting block 11. The contact head 7 drives the lifting block 11 to press the terminal wire, making the terminal wire less prone to shaking. Through the cooperation of the male terminal 1 and the reinforcing connection mechanism 2, the mechanical connection strength between the male terminal 1 and the female terminal 101 is enhanced, so that it can maintain stable contact in the vibration environment and avoid loosening or disconnection. The design of the sealing gasket 208 provides an adaptive seal to prevent external dust, moisture and other substances from entering the connector and improve environmental adaptability. Through the linkage mechanism of the pressing block 4, the connecting rod 6, the contact head 7 and the lifting block 11, the terminal wire is automatically pressed during insertion, reducing poor contact caused by vibration and improving the reliability of electrical connection.

[0027] Refer to the instruction manual appendix Figure 1-6The shielding mechanism 3 includes a housing 304 fixedly connected to the inner wall of the female terminal 101. A metal foil 302 is fixedly connected inside the housing 304. The housing 304 provides space for subsequent parts. An outer coil 303 is sleeved on the outer wall of the metal foil 302. A coil frame 301 is fixedly connected to the inner wall of the metal foil 302. The shielding is strengthened by the structure of the metal foil 302, etc. By setting the shielding mechanism 3, the combination structure of the metal foil 302 and the outer coil 303 effectively suppresses electromagnetic interference and ensures the stability of signal transmission. It is suitable for high-precision sensor applications and provides physical protection through the housing 304, while enhancing the overall shielding effect.

[0028] The working principle of this practical application is as follows:

[0029] Refer to the instruction manual appendix Figure 1-6 During connection, when the male terminal 1 is inserted into the female terminal 101, the first insertion block 202 snaps into the third insertion slot 206, and at the same time, the second insertion block 203 is inserted into the second insertion slot 205, forming multi-point fixation and enhancing the connection strength. The reinforcing block 207 in the extension column 201 provides additional support. The sealing gasket 208 is deformed under pressure during the insertion process to achieve self-adaptive sealing. At this time, the squeezing block 4 in the female terminal 101 pushes the connecting rod 6, causing the contact head 7 to move upward. The contact head 7 pushes the lifting block 11, causing the squeezing head at its top to press the terminal wire tightly, preventing poor contact caused by vibration. The elastic block 10 provides reverse elastic force to ensure that the lifting block 11 can automatically reset during insertion and removal, maintaining stable contact pressure. When the male terminal 1 is connected to the female terminal 101, the metal foil 302 and the outer coil 303 together form a shielding layer to absorb or reflect external electromagnetic interference and protect the internal signal from being affected.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
