Description

Technical Field

[0001] This utility model relates to the field of electrical and electronic equipment technology, and is an electrical connector with a gap self-compensation structure. Background Technology

[0002] An electrical connector is an electromechanical component used to connect circuits or electronic devices, enabling the transmission and isolation of current and signals. It is widely used in automotive, communications, industrial, and consumer electronics industries. It consists of a male and a female connector. The male connector is equipped with conductive metal pin-shaped contacts, while the female connector has conductive metal contact grooves. Electrical connection is achieved by inserting the pin-shaped contacts into the contact grooves.

[0003] In existing technologies, both the pin-shaped contact and the contact groove are fixed to the mounting bases of the male and female connectors, lacking a buffer structure. During the initial connection phase, it is difficult to achieve perfect, zero-error alignment between the pin-shaped contact and the contact groove, causing obstruction during insertion. Some users may use excessive force when encountering this obstruction, leading to deformation and damage to the contact. Furthermore, some users, fearing a weak connection, may apply excessive force when connecting the male and female connectors, resulting in further damage to the contact. Moreover, in environments with significant vibration, the vibration transmitted to the contact and contact groove can easily loosen them, creating gaps and leading to poor contact. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects and provide an electrical connector with a gap self-compensation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electrical connector with a gap self-compensation structure, comprising a male connector and a female connector. The male connector includes a first fixing seat and contact members, the contact members being fixed on the first fixing seat. The female connector includes a second fixing seat and a contact groove assembly. The contact groove assembly includes a connecting groove, a groove seat, a telescopic groove, and a spring. The number of connecting grooves corresponds to the number of contact members and is fixed on the groove seat. The groove seat is slidably disposed within the telescopic groove, and the telescopic groove is fixed on the second fixing seat. The spring is located between the telescopic groove and the groove seat, and its two ends are fixedly connected to both of them respectively. The first fixing seat and the second fixing seat are also respectively provided with a limiting member and a limiting groove. After the male connector and the female connector are connected, the limiting member is engaged in the limiting groove, at which time a buffer gap exists between the first fixing seat and the second fixing seat.

[0006] Furthermore, the first fixing seat is provided with a sleeve-shaped protective cover, the contact element is located inside the protective cover, and the second fixing seat is provided with a groove corresponding to the protective cover, the protective cover is inserted into the groove.

[0007] Furthermore, the groove seat is located within the groove, and a deformable sealing ring is provided between the inner wall of the groove and the outer wall of the groove seat. The two sides of the sealing ring are respectively bonded and fixed to the inner wall of the groove and the outer wall of the groove seat.

[0008] Furthermore, the sealing ring is made of rubber and has a hollow structure.

[0009] Furthermore, after the male and female connectors are connected, there is a buffer gap between the end face of the protective cover and the sealing ring.

[0010] Furthermore, the limiting member includes a deformation area and a snap-fit ​​area. One end of the deformation area is fixed to the first fixing base, and the other end is fixedly connected to the snap-fit ​​area. The limiting groove includes a receiving area and a limiting through hole. The deformation area cooperates with the receiving area, and the limiting through hole cooperates with the snap-fit ​​area. The end of the snap-fit ​​area near the first fixing base is provided with an abutment surface and an arc-shaped extrusion surface. After the male and female heads are connected, the abutment surface abuts against the end face of the limiting through hole near the first fixing base. The end of the limiting through hole away from the first fixing base provides a buffer space for the snap-fit ​​area, and the end of the snap-fit ​​area away from the abutment surface is a slope.

[0011] Furthermore, both the first and second fixing seats are provided with annular sealing gaskets on their end faces. The annular sealing gaskets are deformable, and after the male and female heads are connected, the two annular sealing gaskets come into contact.

[0012] The beneficial effects of this utility model are as follows: The slot seat of this utility model is slidably disposed in the telescopic groove, and a spring is provided in the telescopic groove. When the contact member and the contact groove are not fully aligned, pushing the male head will move the contact member toward the contact groove, and the slot seat can retract the telescopic groove appropriately to prevent deformation or damage to the contact member due to brute force insertion.

[0013] During the insertion process, once insertion is complete, the deformation area of ​​the limiting component will cause the locking area to engage with the limiting through hole, producing a sound to indicate that the insertion is complete. If the contact component is further pushed into the contact groove, the spring will compress, effectively preventing damage to the contact component due to over-insertion.

[0014] After the male and female connectors are connected, a buffer gap one is provided between fixed base one and fixed base two, and a buffer gap two is provided between the end face of the protective cover and the sealing ring. The end of the limiting through hole away from fixed base one provides buffer space for the snap-fit ​​area to cope with vibration. During use, the spring always applies a thrust towards the contact element to the slot seat, ensuring that the contact element and the contact slot are tightly fitted after the male and female connectors are connected, preventing them from loosening and separating due to vibration.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] Embodiments of this utility model: such as Figure 1-5 As shown, an electrical connector with a gap self-compensation structure includes a male connector 1 and a female connector 2. The male connector 1 includes a fixing base 3 and a contact 4, which is fixed on the fixing base 3. The female connector 2 includes a fixing base 5 and a contact groove assembly. The contact groove assembly includes a connecting groove 6, a groove seat 7, a telescopic groove 8, and a spring 9. The number of connecting grooves 6 corresponds to the number of contact 4, and they are fixed on the groove seat 7. The groove seat 7 is slidably disposed in the telescopic groove 8, which is fixed on the fixing base 5. The spring 9 is located between the telescopic groove 8 and the groove seat 7, and its two ends are fixedly connected to both of them. The fixing base 3 and the fixing base 5 are also provided with a limiting member 11 and a limiting groove 12, respectively. After the male connector 1 and the female connector 2 are connected, the limiting member 11 is inserted into the limiting groove 12. At this time, there is a buffer gap 10 between the fixing base 3 and the fixing base 5.

[0019] It is worth noting that the end of the contact element 4 is an arc-shaped structure, and the outer end of the connecting groove 6 is chamfered, making it easier for the two to fit together.

[0020] It is worth noting that the ends of multiple connecting slots 6 away from the contact 4 are connected to wires. All wires pass through the slot seat 7 and the telescopic slot 8 and converge into a single cable. The ends of multiple contact 4 away from the connecting slots 6 are connected to wires, and the multiple wires converge into a single cable (not shown in the figure).

[0021] With the above structure, after the male head 1 and the female head 2 are separated, the spring 9 is in an initial uncompressed state. When the two are connected, when the contact 4 and the contact groove 8 are aligned, the contact 4 moves towards the contact groove 8, and the spring 9 is compressed to prevent damage to the contact 4. When the male head 1 and the female head 2 are connected, the spring 9 is in a slightly compressed state to ensure that a force towards the contact 4 is always applied to the groove seat 7 after the connection is completed. During vibration, under the cooperation of the limiting member 11 and the limiting groove 12, the male head 1 and the female head 2 always remain connected. A buffer gap is reserved between the two fixed seats. During vibration, the contact 4 can move further towards the connecting groove 6, so that the groove seat 7 moves along the telescopic groove 8, and the spring 9 is further compressed. The spring 9 returns to its original position and drives the groove seat 7 to reset, thereby ensuring that the contact 4 and the contact groove 8 are tightly connected and do not loosen.

[0022] like Figure 2 , 3 As shown, the first fixing seat 3 is provided with a sleeve-shaped protective cover 14, the contact member 4 is located inside the protective cover 14, and the second fixing seat 5 is provided with a groove 15 corresponding to the protective cover 14, and the protective cover 14 is inserted into the groove 15.

[0023] With the above structure, when the male head 1 is not connected to the female head 2, the protective cover 14 protects the contact 4 and prevents the contact 4 from being squeezed, deformed and damaged.

[0024] like Figure 4 As shown, the groove 7 is located inside the groove 15, and a deformable sealing ring 16 is provided between the inner wall of the groove 15 and the outer wall of the groove 7. The two sides of the sealing ring 16 are respectively bonded and fixed to the inner wall of the groove 15 and the outer wall of the groove 7.

[0025] like Figure 4 As shown, the sealing ring 16 is made of rubber and has a hollow structure.

[0026] With the above structure, the sealing ring 16 can ensure a seal and prevent water ingress that could cause short circuits; the sealing ring 16 can deform appropriately during the movement of the slot seat 7, thus ensuring the sealing effect without affecting the movement of the slot seat 7.

[0027] After the male head 1 and female head 2 are connected, there is a buffer gap 13 between the end face of the protective cover 14 and the sealing ring 16.

[0028] The above structure facilitates the movement of the slot 7.

[0029] like Figure 2 , 3As shown in Figure 5, the limiting member 11 includes a deformation area 17 and a snap-fit ​​area 18. One end of the deformation area 17 is fixed to the fixing base 3, and the other end is fixedly connected to the snap-fit ​​area 18. The limiting groove 12 includes a receiving area 19 and a limiting through hole 20. The deformation area 17 cooperates with the receiving area 19, and the limiting through hole 20 cooperates with the snap-fit ​​area 18. The snap-fit ​​area near the fixing base 3 has an abutment surface 21 and an arc-shaped extrusion surface 22. After the male head 1 and the female head 2 are connected, the abutment surface 21 abuts against the end face of the limiting through hole 20 near the fixing base 3. The end of the limiting through hole 20 away from the fixing base 3 provides a buffer space for the snap-fit ​​area 18. The end of the snap-fit ​​area 18 away from the abutment surface 21 is a slope, which facilitates the limiting member 11 to extend into the limiting groove 12.

[0030] With the above structure, when the male connector 1 and the female connector 2 are connected, the inclined surface of the locking area 18 first contacts the edge of the receiving area 19, thereby squeezing and deforming the deformation area 17. When the locking area 18 is aligned with the limiting through hole 20, the deformation area 17 drives the locking area 18 to reset, locking into the limiting through hole 20 and producing a sound to indicate that the connection is in place. After the male connector 1 and the female connector 2 are connected, when there is no vibration, the abutting surface 21 of the locking area 18 abuts against the outer end face of the limiting through hole 20 to prevent the male connector 1 and the female connector 2 from separating. Since the end of the limiting through hole 20 away from the fixed base 3 has reserved a buffer space for the snap-fit ​​area 18, the snap-fit ​​area 18 can move toward the other end of the limiting through hole 20 when vibrating; when the male head 1 and the female head 2 are separated, the snap-fit ​​area 18 is pressed from the outside of the limiting through hole 20, so that the arc-shaped extrusion surface 22 contacts the connecting edge of the limiting through hole 20 and the receiving area 19, and the male head 1 is pulled outward, so that the arc-shaped extrusion surface 22 is extruded, causing the deformation area 17 to deform, so that the limiting part 11 can be smoothly dislodged.

[0031] Both the first fixing seat 3 and the second fixing seat 5 are provided with annular sealing gaskets 23. The annular sealing gaskets 23 are deformable. After the male head 1 and the female head 2 are connected, the two annular sealing gaskets 23 are in contact.

[0032] The above structure achieves a sealed connection between male connector 1 and female connector 2, preventing water ingress that could cause short circuits.

[0033] In practical use, the protective cover 14 on the male head 1 is aligned with the groove 15, and the male head is pushed towards the female head 2 so that the two are inserted and engaged. During the insertion process, the limiting member 11 gradually enters the limiting groove 12 and achieves locking and limiting after insertion. During vibration, the setting of buffer gaps one and two allows the male head 1 to continue to move towards the female head 2 during vibration, so that the groove seat 7 moves towards the telescopic groove 8. The spring 9 is compressed, and when the spring 9 returns to its original position, it pushes the groove seat 7 towards the contact member 4, ensuring that the contact member 4 and the connecting groove 6 are always engaged.
