Description

Technical Field

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

[0002] In the design of existing circular connectors, the grounding terminal plays a crucial role. It is not only a key component ensuring the stability of the electrical connection but also an important safeguard for ensuring safe grounding of equipment and preventing leakage accidents. These grounding terminals typically employ a locking structure on the terminal body to create a tight interference fit with the holes in the plastic parts of the connector housing. This design provides good holding force during initial assembly, allowing the grounding terminal to be securely installed in the plastic parts without easily loosening.

[0003] However, in practical use, especially in applications involving high-frequency insertion and removal, this fixing method relying on interlocking points increases the mechanical stress on the grounding terminal due to frequent insertion and removal actions. The interference force between the interlocking point and the plastic hole gradually weakens due to wear. Over time, the grounding terminal is highly susceptible to detachment under external force or vibration. Once the grounding terminal detaches, the connector's grounding function fails, preventing the device from effectively conducting ground, leading to functional abnormalities such as signal interference and unstable current. In severe cases, it may even endanger the normal operation of the equipment and the safety of the user.

[0004] It is evident that the existing method of setting a locking structure on the connector terminal body to form a tight interference fit with the holes in the plastic parts of the connector housing has the problem that the grounding terminal is prone to falling off under high-frequency plugging and unplugging, making the product unable to conduct grounding and causing functional abnormalities. Utility Model Content

[0005] This utility model provides a connector with a grounding function, which aims to solve the problem that existing connectors, which use a locking structure on the terminal body to form a tight interference fit with the holes in the plastic part, are prone to grounding terminal detachment under high-frequency plugging and unplugging, causing the product to fail to conduct grounding and resulting in functional abnormalities.

[0006] This utility model is implemented as follows: Firstly, it provides a connector with a grounding function, comprising a grounding metal terminal, an insulating jacket, and an insulating body; wherein,

[0007] The grounding metal terminal includes a spring arm, an inclined arm extending to one end of the spring arm, and a structural groove extending to the other end of the spring arm.

[0008] The insulating jacket includes a first structural boss, and the structural groove engages with the first structural boss;

[0009] The insulating body includes a structural groove, the elastic arm is received in the structural groove, one end of the inclined arm abuts against one end of the structural groove, the structural groove engages with the other end of the structural groove, and the insulating body is received inside the insulating jacket.

[0010] Furthermore, the insulating body also includes an annular boss, and the insulating jacket also includes a structural cavity that mates with the annular boss, with the annular boss housed within the structural cavity.

[0011] Furthermore, the insulating body also includes an annular base, the annular base being located at the lower end of the annular boss, and the insulating jacket also includes an annular cavity, in which the annular base is received.

[0012] Furthermore, the structural groove extends longitudinally through the insulating body. The structural groove includes a concave groove, which is formed on the annular base. The width and depth of the concave groove are both greater than the width and depth of the structural groove formed on the annular boss, and are used to limit the engagement between the concave groove and the structural groove.

[0013] Furthermore, the insulating jacket also includes a second structural boss, which extends from the first structural boss toward one end near the spring arm, and the second structural boss abuts against the spring arm.

[0014] Furthermore, the second structural boss extends to the middle section of the spring arm.

[0015] Furthermore, the connector also includes an outer roller nut, the inner wall of which is provided with a first thread, and the outer wall of the insulating outer sleeve is provided with a second thread adapted to the first thread, based on the cooperation of the first thread and the second thread to fasten the outer roller nut onto the outer wall of the insulating outer sleeve.

[0016] Furthermore, the outer sleeve roller also includes at least one limiting groove, and the insulating outer sleeve is provided with the same number of limiting blocks as the limiting groove. When the insulating sleeve roller is fitted onto the insulating outer sleeve and reaches the optimal rotation position, the limiting blocks and the limiting groove form a limiting engagement.

[0017] Furthermore, the inclined arm and the spring arm form an angle of 30° to 45° in the horizontal direction.

[0018] Furthermore, the connector also includes a plurality of conductive terminals, each conductive terminal including a limiting end and a connecting end extending to the other end of the limiting end, the plugging end being bent from the limiting end, and the limiting end being plugged into the limiting hole of the insulating body.

[0019] The beneficial effects achieved by this utility model are as follows: By setting a spring arm on the grounding metal terminal, one end of the spring arm extends into a slanted arm, and the other end extends into a structural groove. When the insulating jacket, the insulating body, and the grounding metal terminal are assembled, the spring arm is housed in the structural groove of the insulating body. At the same time, the structural groove, the first structural boss on the insulating jacket, and the structural groove simultaneously form an engagement, and the end of the slanted arm abuts against the structural groove. The three form a stable mechanism, which is more stable. The elastic structure of the grounding metal terminal can also improve stability. When facing high-frequency insertion and removal, the grounding metal terminal will not fall off whether the connector is inserted or removed, so that the connector can maintain normal conduction and grounding, avoid functional abnormalities, and have higher safety.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] This application provides a spring arm on the grounding metal terminal. One end of the spring arm extends into a slanted arm, and the other end extends into a structural groove. When the insulating jacket, the insulating body, and the grounding metal terminal are assembled, the spring arm is housed in the structural groove of the insulating body. At the same time, the structural groove engages with the first structural boss and the structural groove on the insulating jacket, and the end of the slanted arm abuts against the structural groove. The three components form a stable mechanism with enhanced stability. The elastic structure of the grounding metal terminal also improves stability. When subjected to high-frequency insertion and removal, the grounding metal terminal will not fall off regardless of whether the connector is inserted or removed, ensuring that the connector maintains normal conduction and grounding, avoiding functional abnormalities, and enhancing safety.

[0029] Example 1

[0030] Referring to Figure 1, this embodiment of the present invention provides a connector with a grounding function, including a grounding metal terminal 1, an insulating jacket 2, and an insulating body 3; wherein,

[0031] The grounding metal terminal 1 includes a spring arm 11, an inclined arm 12 extending to one end of the spring arm 11, and a structural groove 13 extending to the other end of the spring arm 11.

[0032] The insulating jacket 2 includes a first structural boss 21, and a structural groove 13 engages with the first structural boss 21;

[0033] The insulating body 3 includes a structural groove 31, a spring arm 11 is received in the structural groove 31, one end of the inclined arm 12 abuts against one end of the structural groove 31, and the structural groove 13 engages with the other end of the structural groove 31. The insulating body 3 is received inside the insulating jacket 2.

[0034] The grounding metal terminal 1 is used to implement the grounding function of the connector. The insulating jacket 2 protects the internal conductor, preventing contact with other conductors or the external environment and ensuring electrical isolation. The insulating body 3 serves as a base to precisely fix the positions of the conductive terminal 5 and the grounding metal terminal 1, and separates adjacent terminals and terminals from the housing to prevent internal short circuits. In addition, sealing and isolating the conductive terminal 5 from the external environment also reduces the risk of corrosion. After the grounding metal terminal 1, insulating jacket 2, and insulating body 3 are assembled, the insulating body 3 is housed within the insulating jacket 2. The insulating jacket 2, insulating body 3, and grounding metal terminal can all be integrally molded structures.

[0035] In some examples, a spring arm 11 is included on the grounding metal terminal 1, and the spring arm 11 has a certain elasticity. The spring arm 11 can be straight, S-shaped, or spring-shaped. In this embodiment, the spring arm 11 is straight and can be used as a connecting arm, with one end extending into a slanted arm 12 and the other end extending into a structural groove 13. The slanted arm 12 and the spring arm 11 form a certain angle in the horizontal direction. The side wall of the structural groove 13 connected to the spring arm 11 is shorter than the other side wall, and the relatively longer side wall of the structural groove 13 extends towards the lower end of the insulating body 3 to form a connecting piece 14, on which a grounding hole 15 is provided. The connecting piece 14 is mainly used to connect the grounding terminal to other components or conductors that need to be grounded, ensuring that the current can pass smoothly and achieving good electrical grounding. It can also easily connect or disconnect the grounding wire without complicated welding or bolt fixing, thereby simplifying the installation and maintenance process. The grounding hole 15 can be used to connect an external grounding wire or metal bracket to quickly conduct static electricity or interference current to the ground, preventing sensitive circuits from being impacted by surges. The inclined arm 12, spring arm 11, structural groove 13, connecting piece 14, and connecting hole are all integrally formed structures.

[0036] In some examples, the insulating jacket 2 may include a first structural boss 21. The width of the first structural boss 21 is adapted to the width of the grounding metal terminal 1, and the size of the first structural boss 21 is adapted to the structural groove 13. When the grounding metal terminal 1, the insulating jacket 2 and the insulating body 3 are assembled, the first structural boss 21 can be inserted into the structural groove 13, so that the first structural boss 21 and the structural groove 13 form an engagement and achieve a stable connection.

[0037] In some examples, the insulating body 3 includes a structural slot 31 that extends through the top and bottom of the insulating body 3, and the grounding metal terminal 1 is housed in the structural slot 31. More specifically, after the insulating jacket 2, the insulating body 3, and the grounding metal terminal 1 are assembled, the top end of the inclined arm 12 abuts against the inner wall of the upper end of the structural slot 31, the spring arm 11 is housed in the middle section of the structural slot 31, and the structural groove 13 engages with the first structural boss 21 and the lower end of the structural slot 31. Thus, the grounding metal terminal 1 is limited and fixed by the first structural boss 21 and the structural slot 31, and the three are tightly held together.

[0038] In this embodiment of the utility model, a spring arm 11 is provided on the grounding metal terminal 1. One end of the spring arm 11 extends into a slanted arm 12, and the other end extends into a structural groove 13. When the insulating jacket 2, the insulating body 3, and the grounding metal terminal 1 are assembled, the spring arm 11 is housed in the structural groove 31 of the insulating body 3. At the same time, the structural groove 13 engages with the first structural boss 21 and the structural groove 31 on the insulating jacket 2, and the end of the slanted arm 12 abuts against the structural groove 31. The three form a stable mechanism with stronger stability. The elastic structure of the grounding metal terminal 1 also improves stability. When facing high-frequency insertion and removal, the grounding metal terminal 1 will not fall off whether the connector is inserted or removed, so that the connector can maintain normal conduction and grounding, avoid functional abnormalities, and have higher safety.

[0039] Example 2

[0040] Combination Figure 1 and Figure 2 As shown, in some optional embodiments, the insulating body 3 further includes an annular boss 32, and the insulating jacket 2 further includes a structural cavity 22 that mates with the annular boss 32, with the annular boss 32 housed in the structural cavity 22.

[0041] In this embodiment, the insulating body 3 is cylindrical in shape. An annular protrusion 32 is exposed at one end of the insulating body 3 near the grounding terminal, extending outward from the outer wall of the insulating body 3. The insulating outer sleeve 2 may include a structural cavity 22 corresponding to the annular protrusion 32. The structural cavity 22 is located on the lower inner wall of the insulating outer sleeve 2 and is annular in shape. When the insulating body 3 and the insulating outer sleeve 2 are assembled, the annular protrusion 32 is received within the structural cavity 22, achieving a limiting position, allowing the insulating body 3 to be stably placed within the insulating outer sleeve 2. Furthermore, the annular arrangement further improves the connection stability between the insulating body 3 and the insulating outer sleeve 2.

[0042] In other embodiments, the annular boss 32 may also be a plurality of protrusions arranged circumferentially along the outer wall of the insulating body 3. The structural cavity 22 on the insulating jacket 2 may also be replaced with a positioning groove for accommodating the protrusions. When the insulating body 3 and the insulating jacket 2 are assembled, each protrusion is inserted into the positioning groove at the corresponding position, which can also achieve limiting and fixing, so as to securely install the insulating body 3 inside the insulating jacket 2 without affecting the opening of the structural groove 13.

[0043] In this embodiment, by forming an annular protrusion 32 on the insulating body 3 and a structural cavity 22 on the insulating outer sleeve 2, the annular protrusion 32 is limited and fixed by the structural cavity 22 after the two are assembled, so that the insulating body 3 can be stably placed in the insulating outer sleeve 2, and the annular arrangement can further improve the connection stability between the insulating body 3 and the insulating outer sleeve 2.

[0044] Example 3

[0045] Combination Figure 1 and Figure 2 As shown, in some optional embodiments, the insulating body 3 further includes an annular base 33, which is located at the lower end of the annular boss 32. The insulating jacket 2 also includes an annular cavity 23, in which the annular base 33 is received.

[0046] In this embodiment, the bottom end of the insulating body 3 also includes an annular base 33, which is located below the annular protrusion 32. The annular base 33 can be formed by extending the insulating body 3 from top to bottom. The upper end of the insulating body 3 can be the end of the conductive terminal 5 that is not exposed, and the lower end of the insulating body 3 can be the end of the conductive terminal 5 that is exposed. The insulating jacket 2 also includes an annular cavity 23 for receiving the annular base 33. When the insulating body 3 and the insulating jacket 2 are assembled, the annular protrusion 32 is limited by the structural cavity 22, and the downwardly extending annular base 33 will be received in the annular cavity 23 to ensure that the annular base 33 will not protrude outward, thereby achieving better protection and improving safety. In addition, when the annular boss 32 is set on the upper end of the annular base 33 and the structural groove 31 is opened on the insulating body 3, one side wall of the structural groove 13 is limited by the side wall of the annular boss 32, and the other side wall is limited by the outer bottom of the annular cavity 23. The structural groove 31 near one end of the annular base 33 can better engage with the structural groove 13, while ensuring that the connecting piece 14 of the grounding metal terminal 1 extends outward.

[0047] Example 4

[0048] In some alternative embodiments, combined with Figure 3 As shown, the structural slot 31 extends longitudinally through the insulating body 3. The structural slot 31 includes a concave slot 311, which is formed on the annular base 33. The width and depth of the concave slot 311 are greater than the width and depth of the structural groove 13 formed on the annular boss 32, and are used to limit the engagement between the concave slot 311 and the structural groove 13.

[0049] In this embodiment, the structural slot 31 extends longitudinally through the insulating body 3. The upper end of the structural slot 31 is used to accommodate the inclined arm 12 and the spring arm 11, and the lower end is used to engage with the structural groove 13. A concave slot 311 extends from the lower end of the structural slot 31 and is formed on the annular base 33. The width of the concave slot 311 is wider than the width of the structural groove 13 on the annular boss 32, and the depth of the concave slot 311 is also deeper than the depth of the structural groove 13 on the annular boss 32. For example, the width is 1 cm and the depth is 0.5 cm. When the concave slot 311 and the structural groove 13 are assembled and engaged, the width and depth of the structural groove 13 on the annular boss 32 are smaller than the width and depth of the concave slot 311. Therefore, the annular boss 32 can limit the structural groove 13 placed in the concave slot 311. Especially during high-frequency insertion and removal of the connector, the engagement of the first structural boss 21 and the structural groove 13 prevents the grounding metal terminal 1 from moving in the direction of stress due to the stress generated during insertion and removal, thus preventing loosening. This improves the stability of the grounding metal terminal 1 in the connector, ensuring the grounding function and safety of the connector.

[0050] In this embodiment, by creating the concave groove 311 of the structural groove 13 on the annular base 33, and controlling the width and depth of the concave groove 311 to be greater than the width and depth of the structural groove 13 created on the annular boss 32, the structural groove 13 placed in the concave groove 311 can be limited based on the annular boss 32. Even when the connector is in a high-frequency insertion and removal state, the engagement between the first structural boss 21 and the structural groove 13 will prevent the grounding metal terminal 1 from moving in the direction of stress due to the stress generated during insertion and removal. This helps to improve the stability of the grounding metal terminal 1 in the connector, thereby ensuring the grounding function and safety of the connector.

[0051] Example 5

[0052] Combination Figure 1 and Figure 2 As shown, in some optional embodiments, the insulating jacket 2 further includes a second structural boss 24, which extends from the first structural boss 21 toward one end near the spring arm 11, and the second structural boss 24 abuts against the spring arm 11.

[0053] In this embodiment, a second structural boss 24 may be provided in the insulating jacket 2, and the second structural boss 24 may be formed by extending from the first structural boss 21 towards the end near the spring arm 11. The first structural boss 21 and the second structural boss 24 may be in the shape of a two-tiered boss. The extended second structural boss 24 is close to the spring arm 11, which can limit the movement of the spring arm 11. When the connector is plugged in or unplugged, the grounding metal terminal 1 is subjected to stress, which will cause a certain degree of compression to the spring arm 11. By using the second structural boss 24 to abut against the spring arm 11, it can prevent the spring arm 11 from generating excessive elastic force and causing deformation, thereby improving the connection stability of the grounding metal terminal 1 in the connector.

[0054] In some preferred embodiments, the second structural boss 24 extends to the middle section of the spring arm 11.

[0055] Extending the second structural protrusion 24 to the middle section of the elastic arm 11 can better resist the influence of stress on the elastic arm 11. Extending it to the middle section also ensures the necessary elastic space for the inclined arm 12. This prevents the inclined arm 12 from being compressed and losing its elastic space due to the second structural protrusion 24 being extended too far or too close to it, and also prevents the elastic arm 11 from being weakened due to the second structural protrusion 24 being extended too short. For example, the second structural protrusion 24 can extend to half the length of the elastic arm 11.

[0056] In this embodiment, by extending a second structural boss 24 from the first structural boss 21 to abut against the spring arm 11, the impact of stress on the spring arm 11 during connector insertion and removal can be reduced. Extending the second structural boss 24 to the middle section of the spring arm 11 is more conducive to enhancing the stress resistance of the spring arm 11, while not restricting the elastic space of the inclined arm 12.

[0057] Example 6

[0058] Combination Figure 4 and Figure 5 As shown, in some optional embodiments, the connector further includes an outer sleeve roller 4, the inner wall of which is provided with a first thread 41, and the outer wall of the insulating sleeve 2 is provided with a second thread 25 adapted to the first thread 41, based on the cooperation of the first thread 41 and the second thread 25 to securely fit the outer sleeve roller 4 onto the outer wall of the insulating sleeve 2.

[0059] In this embodiment, the outer sleeve roller nut 4 is used to fit onto the outer wall of the insulating outer sleeve 2 to fasten the insulating outer sleeve 2. The outer sleeve roller nut 4 can be annular. A first thread 41 is provided on the inner wall of the outer sleeve roller nut 4, and a second thread 25 adapted to the first thread 41 is provided on the outer wall of the insulating outer sleeve 2, so that the outer sleeve roller nut 4 can rotate up and down on the outer wall of the insulating outer sleeve 2 based on the first thread 41 and the second thread 25. When rotating upward, it is used to fasten the insulating outer sleeve 2, and when rotating downward, it is used to loosen the insulating outer sleeve 2.

[0060] In this embodiment, by fitting the outer sleeve nut 4 onto the insulating sleeve 2, not only is it beneficial to secure the insulating sleeve 2, but the insulation effect is also further enhanced, ensuring that the current flows within the expected path and avoiding contact with the equipment housing or other non-conductive components. Furthermore, when the connector is used in harsh environments such as high voltage, high temperature, or high humidity, the requirements for insulation and connection are even higher. Therefore, fitting the outer sleeve nut 4 onto the insulating sleeve 2 can also improve the insulation level and connection reliability of the equipment, thereby reducing the risk of safety accidents caused by electrical faults.

[0061] Example 7

[0062] Combination Figure 5 and Figure 6 As shown, in some optional embodiments, the outer sleeve roller 4 also includes at least one limiting groove 42, and the insulating outer sleeve 2 is provided with the same number of limiting blocks 26 as the limiting groove 42. When the insulating roller 4 is fitted onto the insulating outer sleeve 2 and reaches the optimal rotation position, the limiting blocks 26 and the limiting groove 42 form a limiting engagement.

[0063] In this embodiment, to enhance the connection stability between the outer sleeve roller nut 4 and the insulating sleeve 2, a limiting groove 42 can be provided on the upper end of the outer sleeve roller nut 4, and a limiting block 26 can be provided on the upper limiting ring of the insulating sleeve 2 facing the limiting groove 42. When the outer sleeve roller nut 4 rotates to the upper end of the insulating sleeve 2 and approaches the limiting block 26, it continues to rotate upward. The limiting block 26 will enter the limiting groove 42 to achieve limiting. When the limiting block 26 enters the limiting groove 42, it indicates that the optimal rotation position has been reached, and it cannot continue to rotate upward. If it is to rotate downward, due to the rotation of the thread, the force required to loosen is less than the force required to tighten. Therefore, if the outer sleeve roller nut 4 is to be removed, force can be applied.

[0064] In some examples, at least one limiting groove 42 can be provided on the outer roller nut 4, for example, one, two, three, etc. The number of limiting blocks 26 corresponds to the number of limiting grooves 42. The limiting blocks 26 can be elastic or rigid. If the limiting blocks 26 are elastic, it will be more advantageous for them to enter or exit the limiting grooves 42 during rotation, facilitating assembly and disassembly and reducing wear.

[0065] In other examples, the limiting block 26 can also be a rounded square or a sphere. Correspondingly, the limiting groove 42 can be a rounded recess or a spherical groove, and the opening of the limiting groove 42 can also be enlarged. This arrangement facilitates the entry and exit of the limiting block 26 into the limiting groove 42.

[0066] In this embodiment, by setting a limiting groove 42 on the outer sleeve roller 4 and a corresponding limiting block 26 on the insulating outer sleeve 2, when the outer sleeve roller 4 rotates to the optimal rotation position on the insulating outer sleeve 2, the limiting block 26 enters the limiting groove 42 to achieve limiting, thereby preventing the insulating roller 4 from becoming loose on the insulating outer sleeve 2 and improving the tightness of the connection between the insulating outer sleeve 2 and the insulating body 3 and the grounding terminal.

[0067] Example 8

[0068] In some alternative embodiments, the inclined arm 12 and the spring arm 11 form an angle of 30° to 45° in the horizontal direction.

[0069] In this embodiment, controlling the angle between the inclined arm 12 and the spring arm 11 in the horizontal direction between 30° and 45° is more conducive to achieving optimal elastic performance between the spring arm 11 and the inclined arm 12, so as to cope with the stress generated by connector insertion and removal in the best state, and to prevent deformation of the grounding metal terminal 1. If the angle is higher or lower than the above-mentioned angle range, the inclined arm 12 and the spring arm 11 cannot achieve the best stress resistance. For example, when it is less than 30°, the friction between the inclined arm 12 and the structural groove 31 is smaller, and the resistance to loosening of the grounding metal terminal 1 caused by the stress generated by connector insertion and removal is smaller; when it is greater than 45°, the friction between the inclined arm 12 and the structural groove 31 is larger, and the resistance to loosening of the grounding metal terminal 1 caused by the stress generated by connector insertion and removal is too large, and it may even cause the end of the inclined arm 12 to fail to exert its elastic performance in the groove of the structural groove 31 and directly get stuck in the groove.

[0070] In some examples, when the included angle is 30°, if the connector is in the plugged-in state, the grounding metal terminal 1 is subjected to upward stress, and the tip of the extended angled arm 12 may rub more forcefully against the groove of the structural slot 31. In this case, the stress requirement for the spring arm 11 is lower when the angled arm 12 is extended. When the included angle is 45°, if the connector is in the plugged-in state, the grounding metal terminal 1 is subjected to upward stress, and the tip of the extended angled arm 12 may rub more forcefully against the groove of the structural slot 31. In this case, the stress requirement for the spring arm 11 is higher than that at 30°. If the connector is in the unplugged state, the stress on both the spring arm 11 and the angled arm 12 is smaller.

[0071] In this embodiment, by forming an angle of 30° to 45° in the horizontal direction between the inclined arm 12 and the spring arm 11, when the connector is in a high-frequency insertion and removal state for a long time, it is more conducive to the inclined arm 12 and the spring arm 11 maintaining better elastic performance, thereby enhancing the stability of the grounding metal terminal 1 and reducing the possibility of the grounding metal terminal 1 falling off.

[0072] Example 9

[0073] Combination Figure 4 As shown, in some optional embodiments, the connector further includes a plurality of conductive terminals 5, each conductive terminal 5 including a limiting end 51 and a connecting end 52 extending to the other end of the limiting end 51. The plug-in end and the limiting end 51 are bent, and the limiting end 51 is plugged into the limiting hole 34 of the insulating body 3.

[0074] In this embodiment, to enable electrical conductivity between the connector and other electronic devices or components, a plurality of conductive terminals 5 are also included. The conductive terminals 5 are fixed based on the insulating body 3. Specifically, a number of limiting holes 34 corresponding to the number of conductive terminals 5 can be formed on the insulating body 3. The limiting ends 51 of the conductive terminals 5 are inserted into the limiting holes 34 for fixing, while the connecting ends 52 are exposed for connection with other electronic devices or components.

[0075] The connecting end 52 and the limiting end 51 can be curved or straight. In this embodiment, the connector includes 6 conductive terminals. One straight conductive terminal is inserted into the limiting hole 34 in the middle of the bottom of the insulating body 3. Five limiting holes 34 are provided around the middle limiting hole 34 for inserting 5 curved conductive terminals.

[0076] In this embodiment, multiple conductive terminals 5 are installed on the insulating body 3, which can be used to realize the conductive function with other electronic devices or devices.
