Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically a robust sensor connector. Background Technology
[0002] As people's living standards improve, they are paying more and more attention to their personal health. As a result, many families are equipped with blood glucose meters. In order to obtain accurate data when conducting blood glucose tests, continuous blood glucose monitoring is generally used. The blood glucose sensor is inserted into the body through a device, and the sensor transmits the data back to the meter. The patent, CN223109274U, entitled "A Compact Connector," describes a connector as follows: "A compact connector includes a housing and a cover disposed on the upper side of the housing. The housing has a placement section for accommodating a sensor. Two rows of end spring tabs are fixedly connected within the placement section via in-mold molding. The end spring tabs are staggered, dividing the placement section into several cavities. Several positioning posts for clamping the sensor are staggered and fixedly connected to the lower surface of the cover. When the cover and housing are assembled, the positioning posts precisely insert into the cavities. The housing has slots facing upwards that mate with the sensor, with the slots located on opposite sides of the housing. This connector design optimizes space utilization by dividing the cavities with staggered end spring tabs, resulting in a compact structure. The cover and housing achieve a quick and stable connection through precisely matched positioning posts, improving assembly efficiency and component stability. The end spring tabs are fixed to the housing using in-mold molding technology, enhancing impact and vibration resistance and effectively extending the equipment's lifespan. Overall, it balances space efficiency, ease of assembly, and durability." However, the end spring tabs lack support and rely solely on their own strength to maintain their shape, making them prone to deformation over prolonged use. Summary of the Invention
[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides a robust sensor connector that can effectively solve the problem mentioned in the background technology that the end bullet piece has no support and relies solely on its own strength to maintain its shape, making it prone to deformation after long-term use.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a stable sensor connector, including a circuit board and a through hole, a housing disposed above the circuit board, a placement part disposed in the middle of the housing for accommodating the sensor, an end spring clip snapped in the placement part, and a sensor abutting against the end spring clip in the placement part, comprising: A slot is provided in the middle of the housing, and the slot passes longitudinally through all the placement parts; The end bullet pieces of the placement part are arranged vertically and staggered, and the front ends of the end bullet pieces all face the slot direction; The bottom of the placement part is provided with a crossbeam, and a limiting groove is provided on one side of the crossbeam. When the end bullet is placed into the placement part, the bullet is inserted into the limiting groove and contacts the crossbeam.
[0005] Furthermore, the end bullet includes a bullet base, the lower end of which is connected to a forward-bent bullet abutment portion, and the lower end of which is connected to a backward-bent bullet connecting portion.
[0006] Furthermore, the spring clip connecting part has an L-shaped structure.
[0007] Furthermore, the contact portion of the spring sheet has a Z-shaped structure.
[0008] Furthermore, the bottom of the housing is provided with a positioning post, and the circuit board is provided with a positioning hole. When the housing is installed on the circuit board, the positioning post and the positioning hole engage with each other.
[0009] Furthermore, a welding part is provided at the outer edge of the through hole.

Detailed Implementation
[0013] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0014] 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.
[0015] like Figure 1-6 As shown, this utility model provides a robust sensor 3 connector, including a circuit board 4 and a through hole 6, a housing 1 disposed above the circuit board 4, a placement part 9 disposed in the middle of the housing 1 for accommodating the sensor 3, an end spring clip 2 snapped into the placement part 9, and a sensor 3 abutting against the end spring clip 2 in the placement part 9. A slot 8 is provided in the middle of the housing 1, and the slot 8 passes longitudinally through all the placement parts 9; The end bullet pieces 2 of the placement part 9 are arranged vertically and staggered, and the front end of each end bullet piece 2 faces the slot 8. A crossbeam 10 is provided at the bottom of the placement part 9. A limiting groove 11 is provided on one side of the crossbeam 10. When the end bullet piece 2 is placed into the placement part 9, the bullet piece is inserted into the limiting groove 11 and contacts the crossbeam 10.
[0016] By connecting all placement parts 9 in series through the longitudinal slots 8, an integral structural frame is formed, so that the lateral force on the sensor 3 when it is inserted is evenly distributed to the entire housing 1, avoiding loosening or breakage of the connection caused by local stress concentration.
[0017] See Figure 6 The end bullet fragment 2 includes a fragment base 21, the lower end of the fragment base 21 is connected to a forward-bent fragment abutment part 22, and the lower end of the fragment base 21 is connected to a backward-bent fragment connecting part 23.
[0018] The spring contact part 22 bends forward. When the sensor 3 is inserted, the front end of the spring contact part 22 is compressed and undergoes elastic deformation, forming a "pre-tightening force". Through the lever principle, the axial force when the sensor 3 is inserted is converted into the lateral elastic deformation of the spring contact part 22, so that the pressure on the contact surface is evenly distributed, avoiding spring breakage or poor contact caused by local stress concentration.
[0019] The forward-bending arc structure can disperse stress, reduce metal fatigue caused by repeated insertion and removal or vibration, and extend the service life of the spring.
[0020] The bending angle of the spring contact part 22 can be designed to match the contact surface of the sensor 3, ensuring that stable contact pressure can be maintained at different insertion depths and adapting to the dimensional tolerances of the sensor 3.
[0021] The backward-bent spring contact 23 is fixed to the circuit board 4 or the crossbeam 10 to form a rigid support point. When the spring contact 22 is pressed, the backward-bent contact can withstand the reverse tension, preventing the spring base 21 from dislodging from the limiting groove 11 or the crossbeam 10 due to excessive deformation, thus ensuring structural stability. The contact is fixed to the housing 1 by welding or snap-fitting, transferring the force on the spring to the entire connector structure, thus avoiding damage to the circuit board 4 or the housing 1 caused by local stress concentration.
[0022] See Figure 6 The spring clip connecting part 23 has an L-shaped structure. The L-shaped spring clip connecting part 23 rests on the crossbeam 10 and is tightly attached to the side of the crossbeam 10 to improve stability.
[0023] See Figure 6 The spring contact part 22 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 9 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 2 due to insertion direction deviation, thus improving the efficiency and accuracy of installation.
[0024] See Figure 4 The bottom of the housing 1 is provided with a positioning post 12, and the circuit board 4 is provided with a positioning hole 5. When the housing 1 is installed on the circuit board 4, the positioning post 12 and the positioning hole 5 engage in a snap-fit connection, forming a rigid connection that fixes the housing 1 and the circuit board 4 as one unit. In vibration or impact environments, the snap-fit structure can effectively suppress the relative displacement between the housing 1 and the circuit board 4, preventing the spring from loosening, the solder joint from breaking, or the sensor 3 from making poor contact.
[0025] See Figure 2 A welding part 7 is provided at the outer edge of the through hole 6.
