Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a shorting functional component and connector. Background Technology

[0002] Common shorting components on the market include shorting pins and shorting sockets. The connection stability between the shorting pins and shorting sockets mainly depends on the positive pressure provided by the shorting sockets to the shorting pins.

[0003] For example, Chinese patent CN207282813U discloses a maintenance switch. Paragraph 0032 of the aforementioned patent description states that "a shorting pin 9 with an interlocking circuit function is installed inside the outer sheath 3 of the plug, and a shorting socket 10 for inserting the shorting pin 9 to achieve electrical connection is installed inside the outer sheath 4 of the socket. When the plug 1 is inserted into the socket 2, the shorting pin 9 is inserted into the shorting socket 10, and the maintenance switch is in a closed state, so that the entire electric vehicle circuit is energized; when the plug 1 is pulled out from the socket 2, the shorting pin 9 is also pulled out from the shorting socket 10, and the maintenance switch is in an open state, so that the entire electric vehicle circuit is de-energized, and maintenance work can be performed at this time. The shorting pin 9 and the shorting socket 10 form an interlocking device." That is, when the plug 1 is inserted into the socket 2, the shorting pin is inserted into the shorting socket, and the shorting pin is inserted into the shorting socket through interference contact to complete the electrical connection.

[0004] The connection stability between the shorting pin and the shorting socket mainly depends on the positive pressure provided by the shorting socket to the shorting pin. Low connection stability is not conducive to a more stable electrical connection between the shorting pin and the shorting socket. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a shorting functional component and connector, which solves the technical problem that the connection stability between the shorting pin and the shorting socket mainly depends on the positive pressure provided by the shorting socket to the shorting pin, resulting in low connection stability.

[0006] The technical solution of this utility model is implemented as follows: A shorting functional component includes a shorting pin assembly and a shorting socket assembly. The shorting pin assembly includes a shorting pin and a plastic body. The shorting pin is encased in the plastic body. The shorting socket assembly includes a shorting socket and a shorting socket sleeve. The shorting socket sleeve has an installation hole. The shorting socket is snapped into the installation hole. The shorting pin and the shorting socket are inserted and mated. A hook is integrally connected to the shorting socket sleeve. The plastic body has a locking groove. The hook engages with the locking groove. After the shorting pin and shorting socket of this application are plugged in, the hook on the shorting socket sleeve engages with the locking groove on the plastic body. While the shorting socket provides positive pressure to the shorting pin, the engagement of the hook and locking groove effectively improves the stability of the connection between the shorting pin and the shorting socket. The connection between the shorting pin and the shorting socket is more stable, solving the technical problem that the connection stability between the shorting pin and the shorting socket mainly depends on the positive pressure provided by the shorting socket to the shorting pin, resulting in low connection stability.

[0007] Preferably, the shorting socket sleeve is provided with two hooks, which are symmetrically arranged on the shorting socket sleeve, and the corresponding plastic body is provided with two locking grooves. By using the two symmetrically arranged hooks to engage with the two symmetrically arranged locking grooves on the plastic body, the connection between the shorting pin and the shorting socket is more stable, and the two symmetrically arranged hooks make the shorting socket sleeve structure more symmetrical.

[0008] Preferably, the plastic body has two symmetrically arranged predetermined grooves, and the two hooks are respectively engaged with the two predetermined grooves. The predetermined grooves allow the hooks to be engaged in the predetermined grooves during pre-assembly of the shorting socket and the shorting pin, facilitating the connection between the shorting socket and the shorting pin during pre-assembly and improving the convenience of assembly.

[0009] Preferably, the shorting pin is a 90° bent pin, and the plastic body is a 90° bent plastic body with reinforcing ribs at the bend. The 90° bent shorting pin facilitates the 90° bend of the shorting pin for wire exit, and the reinforcing ribs improve the strength of the bend in the plastic body.

[0010] Preferably, the shorting socket includes a base, one end of which has two spring bodies and the other end has a support body. One end of each of the two spring bodies is integrally connected to the base, and the other end is curled into an elastic socket adapted to the shorting pin. The two ends of the support body are bent to form upper and lower layers of support bodies, and the two ends of the support body are connected by a dovetail groove structure. The upper support body has an integrally connected support structure, and the lower support body has a first through groove. The bent support structure extends into the first through groove. That is, the elastic socket is a ring-shaped structure formed by curling the spring bodies. The ring-shaped elastic socket is inserted into the shorting pin, which effectively improves the vibration resistance of the shorting pin and further increases the stability of the shorting pin and the shorting socket. The spring body has a protrusion, which is formed by bending the spring body towards the inside of the elastic socket. When the spring body is curled to form the elastic socket, the protrusion is arranged around the circumference of the elastic socket. The protrusion is interference-fitted with the shorting pin. The protrusion makes more contact points in the elastic socket, making the connection more reliable. At the same time, it extends the service life and number of times the high-stability electrical connection is used, significantly improving the service life.

[0011] The dovetail groove structure allows the two ends of the support body to be bent and then reconnected, ensuring the support strength after bending and improving the stability of the entire short-connector socket. The dovetail groove structure includes a dovetail groove and a dovetail. One end of the support body has a dovetail groove, and the other end has a dovetail. After the two ends of the support body are bent, they are locked together by the matching of the dovetail and the dovetail groove.

[0012] The support structure is configured with two layers of support bodies arranged to provide support. Preferably, the bottom surface of the lower layer of support body is flush with the end face of the support structure, so that the end face of the support structure can be directly supported.

[0013] Preferably, the base has a second through groove, and the curled end of the spring body extends into the second through groove. The curled end of the spring body extends into the second through groove to provide support for the annular elastic insertion hole, ensuring the stability of the annular elastic insertion hole. Preferably, the end face of the spring body is flush with the bottom surface of the base so that the end face of the spring body can directly provide support for the annular elastic insertion hole.

[0014] Preferably, the support body is provided with an elastic hook, and the shorting socket sleeve is provided with a fixing hole, wherein the elastic hook engages with the fixing hole. The elastic hook is provided to fix the shorting socket and the shorting socket sleeve in place. When the shorting socket is fully inserted into the shorting socket sleeve, the end of the elastic hook is inserted into the fixing hole to achieve the engagement between the shorting socket and the shorting socket sleeve.

[0015] A connector includes a connector housing and the aforementioned shorting functional component. The connector housing has a shorting housing with a step inside. The plastic body of the shorting pin assembly has a cantilever that engages with the step. The shorting socket assembly has a shorting socket sleeve that inserts into the shorting housing. The socket sleeve inserted into the shorting housing is hooked to the plastic body via a hook. The shorting pin assembly is inserted into one end of the shorting housing. After the shorting pin assembly is in place, the cantilever on the plastic body engages with the step, completing the fixed connection between the shorting pin assembly and the shorting housing. Then, the shorting socket assembly is inserted into the other end of the shorting housing. After the shorting socket assembly is inserted into the shorting housing, the hook on the shorting socket sleeve engages with the locking groove on the plastic body, completing the connection between the shorting socket assembly and the shorting pin assembly.

[0016] Preferably, the cantilever is located at the front end of the plastic body, and a limiting block is provided at the rear end of the plastic body. The limiting block engages with the shorting housing. The limiting block is designed to prevent the plastic body from being excessively inserted into the shorting housing. The cantilever at the front end of the plastic body engages with the step inside the shorting housing, and the limiting block at the rear end of the plastic body engages with the end face of the shorting housing. The plastic body is fixed to the shorting housing by the combined engagement of the cantilever and the limiting block.

[0017] Preferably, the plastic body is provided with a positioning block, and the shorting housing is provided with a positioning groove, with the positioning block and the positioning groove slidingly engaged. The positioning block is provided to position the plastic body for insertion, ensuring that the plastic body is inserted along the positioning groove. The positioning block and positioning groove ensure the insertion angle of the plastic body and also help improve the assembly efficiency of the connector.

[0018] The beneficial effects of this utility model are as follows: After the shorting pin and shorting socket of this application are plugged in and matched, the hook on the shorting socket sleeve and the locking groove on the plastic body are engaged and matched. While the shorting socket provides positive pressure to the shorting pin, the connection between the shorting pin and the shorting socket is effectively improved by the engagement of the hook and the locking groove, and the connection between the shorting pin and the shorting socket is more stable.

Detailed Implementation

[0033] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1: A short-circuit functional component, such as Figure 1 , Figure 2 and Figure 3 As shown, the assembly includes a shorting pin assembly and a shorting socket assembly. The shorting pin assembly includes a shorting pin 1 and a plastic body 3. The shorting pin 1 is enclosed within the plastic body 3. The shorting socket assembly includes a shorting socket 2 and a shorting socket sleeve 4. The shorting socket sleeve 4 has a mounting hole 26, and the shorting socket 2 is snapped into the mounting hole 26. The shorting pin 1 and the shorting socket 2 are inserted into each other. A hook 5 is integrally connected to the shorting socket sleeve 4. The plastic body 3 has a locking groove 6, and the hook 5 is engaged with the locking groove 6. After the shorting pin 1 and shorting socket 2 of this application are inserted and mated, the hook 5 on the shorting socket sleeve 4 engages with the locking groove 6 on the plastic body 3. While the shorting socket 2 provides positive pressure to the shorting pin 1, the engagement of the hook 5 and the locking groove 6 effectively improves the stability of the connection between the shorting pin 1 and the shorting socket 2. The connection between the shorting pin 1 and the shorting socket 2 is more stable, solving the technical problem that the connection stability between the shorting pin and the shorting socket mainly depends on the positive pressure provided by the shorting socket to the shorting pin, resulting in low connection stability.

[0035] The shorting pin 1 of this application can be a pin bent at a certain angle, such as a pin bent at 60°, a pin bent at 90°, and a pin bent at 120°; or it can be a pin that is not bent. The specific pin shape and bending angle are designed according to actual needs.

[0036] Example 2, based on Example 1, provides a short-circuit functional component, such as... Figure 1 , Figure 2 and Figure 3 As shown, two hooks 5 are provided on the shorting socket sleeve 4, and the two hooks 5 are symmetrically arranged on the shorting socket sleeve 4. Correspondingly, two locking grooves 6 are arranged on the plastic body 3. The two symmetrically arranged hooks 5 are used to engage with the two symmetrically arranged locking grooves 6 on the plastic body 3. On the one hand, the connection between the shorting pin 1 and the shorting socket 2 is more stable by using the two symmetrically arranged hooks 5. On the other hand, the two symmetrically arranged hooks 5 make the structure of the shorting socket sleeve 4 more symmetrical.

[0037] Example 3, based on Example 2, provides a short-circuit functional component, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the plastic body 3 is symmetrically provided with two predetermined grooves 7, and the two hooks 5 are respectively hooked and engaged with the two predetermined grooves 7. The setting of the predetermined grooves 7 allows the hooks 5 to be hooked into the predetermined grooves 7 during pre-assembly of the shorting socket 2 and the shorting pin 1, which facilitates the connection between the shorting socket 2 and the shorting pin 1 during pre-assembly and improves the convenience of assembly.

[0038] Example 4, based on Example 3, provides a short-circuit functional component, such as... Figure 1 and Figure 2 As shown, the shorting pin 1 is a 90° bent pin, and the plastic body 3 is a 90° bent plastic body. A reinforcing rib 8 is provided at the bend of the plastic body 3. The shorting pin 1 is a 90° bent pin to facilitate the 90° bend of the shorting pin 1 for wire exit. The reinforcing rib 8 improves the strength of the bend of the plastic body.

[0039] Example 5, based on any one of Examples 1 to 4, a short-circuit functional component, such as... Figure 5 and Figure 6 As shown, the shorting socket 2 includes a base 9. One end of the base 9 is provided with two spring bodies 10, and the other end is provided with a support body 11. One end of each of the two spring bodies 10 is integrally connected to the base 9, and the other end is curled into an elastic socket 25 adapted to the shorting pin 1. The two ends of the support body 11 are bent to form an upper and lower layer of support body 11, and the two ends of the support body 11 are connected by a dovetail groove structure 24. The upper support body 11 is integrally connected with a support structure 12, and the lower support body 11 is provided with a first through groove 13. The support structure 12 is bent and extends into the first through groove 13. That is, the elastic socket 25 is a ring structure formed by curling the spring bodies 10. The ring-shaped elastic socket 25 is inserted into the shorting pin 1, which effectively improves the vibration resistance of the shorting pin 1 and further increases the stability of the shorting pin 1 and the shorting socket 2. The spring body 10 has a protrusion, which is formed by bending the spring body 10 toward the inside of the elastic socket 25. After the spring body 10 is curled to form the elastic socket 25, the protrusion is arranged around the circumference of the elastic socket 25. The protrusion is interference-fitted with the shorting pin 1. The protrusion makes more contact points in the elastic socket 25, making the insertion more reliable. At the same time, it extends the service life and number of times the high-stability electrical connection is used, significantly improving the service life.

[0040] The flexible socket 25 refers to a socket that can undergo elastic deformation in the circumferential direction. Because the protrusion is arranged in the circumferential direction of the flexible socket 25, the protrusion is interference-fitted with the shorting pin 1. When the shorting pin 1 is inserted into the flexible socket 25, the protrusion arranged in the circumferential direction of the flexible socket 25 undergoes elastic deformation and contacts the shorting pin 1. Furthermore, the elastically deformed protrusion provides greater positive pressure to the shorting pin 1, making the contact between the elastically deformed protrusion and the shorting pin 1 more stable. Therefore, the socket with the circumferentially arranged protrusion is called the flexible socket 25.

[0041] The dovetail groove structure 24 allows the two ends of the support body 11 to be bent and then reconnected, ensuring the support strength of the support body 11 after bending and improving the stability of the entire short-connection socket 2. The dovetail groove structure 24 includes a dovetail groove and a dovetail. One end of the support body 11 is provided with a dovetail groove, and the other end of the support body 11 is provided with a dovetail. After the two ends of the support body 11 are bent, the two ends of the support body 11 are locked together by the matching of the dovetail and the dovetail groove.

[0042] The support structure 12 is configured to provide support for the upper and lower support bodies 11. Preferably, the bottom surface of the lower support body 11 is flush with the end face of the support structure 12 so that the end face of the support structure 12 can be directly supported.

[0043] Example 6, based on Example 5, provides a short-circuit functional component, such as... Figure 5 and Figure 6 As shown, the base 9 is provided with a second through groove 23, and the curled end of the spring body 10 extends into the second through groove 23. The curled end of the spring body 10 extends into the second through groove 23 so that the curled end of the spring body 10 can provide support for the annular elastic insertion hole and ensure the stability of the annular elastic insertion hole. Preferably, the end face of the spring body 10 is flush with the bottom surface of the base 9 so that the end face of the spring body 10 can directly provide support for the annular elastic insertion hole.

[0044] Example 7, based on Example 6, provides a short-circuit functional component, such as... Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the support body 11 is provided with an elastic hook 14, and the shorting socket sleeve 4 is provided with a fixing hole 15. The elastic hook 14 and the fixing hole 15 are engaged. The elastic hook 14 is provided to fix the shorting socket 2 and the shorting socket sleeve 4. When the shorting socket 2 is fully inserted into the shorting socket sleeve 4, the end of the elastic hook 14 is inserted into the fixing hole 15 to achieve the engagement between the shorting socket 2 and the shorting socket sleeve 4.

[0045] The shorting socket sleeve 4 is provided with a mounting hole 26 and a fixing hole 15 is provided on the wall of the mounting hole 26. The shorting socket 2 can be inserted along the mounting hole 26 on the shorting socket sleeve 4. At the same time, a stop block 27 is connected in the mounting hole 26. The stop block 27 is on the insertion path of the shorting socket 2. When the shorting socket 2 is fully inserted along the mounting hole 26 on the shorting socket sleeve 4, the elastic hook 14 engages with the fixing hole 15. At the same time, the position between the two spring bodies 10 on the shorting socket 2 is engaged with the stop block 27 to ensure a more stable connection between the shorting socket 2 and the shorting socket sleeve 4, and also to prevent the shorting socket 2 from being over-inserted into the socket sleeve 4.

[0046] In Example 7, the shorting pin 1 is bent and wrapped inside the plastic body 3, and then inserted into the shorting socket 2 into the mounting hole 26 of the shorting socket sleeve 4. When the shorting pin assembly and the shorting socket assembly need to be connected and reach the predetermined position, the hook 5 on the shorting socket sleeve 4 engages with the predetermined groove 7 on the plastic body 3. As the socket sleeve 4 is pushed further, the hook 5 on the shorting socket sleeve 4 moves along the plastic body 3 and engages with the locking groove 6 on the plastic body 3. At this time, the shorting pin 1 is inserted into the shorting socket 2, and the shorting pin 1 and the shorting socket 2 are connected.

[0047] Example 8, based on any one of Examples 1 to 7, a connector, such as Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the device includes a connector housing 16 and the aforementioned shorting functional component. The connector housing 16 has a shorting housing 17, and the shorting housing 17 has a step 18 inside. The plastic body 3 of the shorting pin assembly has a cantilever 19, which engages with the step 18. The shorting socket sleeve 4 of the shorting socket assembly is inserted into the shorting housing 17. The socket sleeve 4 inserted into the shorting housing 17 is hooked to the plastic body 3 via a hook 5. The shorting pin assembly is inserted along one end of the shorting housing 17. After the shorting pin assembly is installed, the cantilever 19 on the plastic body 3 engages with the step 18, completing the fixed connection between the shorting pin assembly and the shorting housing 17. Then, the shorting socket assembly is inserted along the other end of the shorting housing 17. After the shorting socket assembly is inserted into the shorting housing 17, the hook 5 on the shorting socket sleeve 4 engages with the locking groove 6 on the plastic body 3, completing the connection between the shorting socket assembly and the shorting pin assembly.

[0048] Example 9, based on Example 8, a connector, such as Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, the cantilever 19 is located at the front end of the plastic body 3, and a limiting block 20 is provided at the rear end of the plastic body 3. The limiting block 20 is engaged with the shorting housing 17. The limiting block 20 is designed to prevent the plastic body 3 from being over-inserted into the shorting housing 17. The cantilever 19 at the front end of the plastic body 3 is engaged with the step 18 inside the shorting housing 17, and the limiting block 20 at the rear end of the plastic body 3 is engaged with the end face of the shorting housing 17. The plastic body 3 is fixed to the shorting housing 17 by the common blocking action of the cantilever 19 and the limiting block 20.

[0049] Example 10, based on Example 9, a connector, such as Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, the plastic body 3 is provided with a positioning block 21, and the shorting housing 17 is provided with a positioning groove 22. The positioning block 21 and the positioning groove 22 are slidably engaged. The positioning block 21 is provided to position the plastic body 3 for insertion, ensuring that the plastic body 3 is inserted along the positioning groove 22. The positioning block 21 and the positioning groove 22 ensure the insertion angle of the plastic body 3 and also help improve the assembly efficiency of the connector.

[0050] In Example 10, a shorting pin assembly is inserted into the front end of the shorting housing 17 on the connector housing 16. The positioning block 21 on the plastic body 3 of the shorting pin assembly corresponds to the positioning groove 22. Then, the shorting pin assembly is inserted, and the positioning block 21 slides in the positioning groove 22 until the cantilever 19 and the step 18 stop and engage. At this time, the limiting block 20 stops and engages with the front end face of the shorting housing 17. Then, the shorting socket assembly is inserted along the rear end of the shorting housing 17. When the shorting socket assembly is in the predetermined position, the hook 5 of the shorting socket sleeve 4 on the shorting socket assembly is engaged with the predetermined groove 7. When the shorting pin assembly needs to communicate with the shorting socket assembly, the shorting socket sleeve 4 is pushed further, and the hook 5 of the shorting socket sleeve 4 is engaged with the locking groove 6. At this time, the shorting pin 1 is inserted into the shorting socket 2 to complete the electrical connection.
