Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular, to an automotive connector. Background Art

[0002] A connector is an electrical device used to connect two conductors so that current or signals can be transmitted from one conductor to another, and is widely used in fields such as communication, security, computers, automobiles, and rail transit.

[0003] Connectors in related technologies usually include a terminal block, a wiring terminal arranged in the terminal block, a pin block, and conductive pins arranged in the pin block. The conductive pins are inserted into the wiring terminal to achieve electrical conduction of the circuit.

[0004] In the process of implementing this application, the inventors found that at least the following problems exist in this technology: when the above connector is applied to the automotive field, since vibrations are inevitably generated during the driving of the vehicle, after the vibrations are transmitted to the connector, the conductive pins are likely to come out of the wiring terminal, which needs to be improved. Summary of the Invention

[0005] In order to improve the insertion stability between the conductive pin and the wiring terminal, this application provides an automotive connector.

[0006] An automotive connector provided by this application adopts the following technical solutions:

[0007] An automotive connector includes a terminal block, a wiring terminal arranged in the terminal block, a pin block, and conductive pins arranged in the pin block. The conductive pins are inserted into the wiring terminal in the horizontal direction. A anti-disengagement component for preventing the conductive pins from coming out of the wiring terminal is arranged on the pin block. The anti-disengagement component includes a bracket fixedly connected to the pin block, a connecting rod vertically slidably penetrating through the bracket, a fixing plate arranged below the connecting rod, and a plurality of anti-disengagement rods arranged below the fixing plate. Anti-disengagement grooves for respectively vertically extending the anti-disengagement rods are formed on the terminal block.

[0008] By adopting the above technical solutions, when assembling the connector, after the conductive pins are horizontally inserted into the wiring terminal, the anti-disengagement rods are vertically extended into the adjacent anti-disengagement grooves, and the anti-disengagement rods can be used to prevent the terminal block and the pin block from moving away from each other, so that the conductive pins are not easily detached from the wiring terminal, the conductive pins are firmly inserted into the wiring terminal, and the connector has high stability and good electrical conductivity.

[0009] Optionally, a contact spring for driving the fixing plate to move towards the terminal block is sleeved outside the connecting rod, and the telescopic direction of the contact spring is parallel to the insertion direction of the anti-disengagement rods.

[0010] By adopting the above technical solution, the abutment spring exerts a force on the fixing plate in the direction of the terminal seat, and this force can drive the anti-dropout rod to remain in the state of extending into the anti-dropout groove, thereby ensuring the limiting effect of the anti-dropout rod on the terminal seat.

[0011] Optionally, two rows of makeshift hole groups are distributed on the terminal seat in the vertical direction, each row of makeshift hole groups has multiple makeshift holes distributed in the horizontal direction, and the wiring terminals are embedded in each makeshift hole; the number of the anti-slip grooves is the same as the number of the makeshift holes in each row of makeshift hole groups, and each anti-slip groove is respectively connected to each makeshift hole in the upper row of makeshift hole groups, and the anti-slip rod can pass through the anti-slip groove and abut against the wiring terminal.

[0012] By adopting the above technical solution, when the anti-drop rod extends into the anti-drop groove under the action of the abutment spring, the wiring terminals located in the upper row of the makeshift hole group will be subjected to the downward pressure of the anti-drop rod, and the pressure can drive the wiring terminals to press the conductive pins inserted therein, thereby further improving the plug-in stability of the conductive pins and the wiring terminals.

[0013] Optionally, the end face of the connecting terminal facing the needle seat is provided with a plug-in slot for the conductive needle to extend into, the upper and lower slot walls of the plug-in slot are respectively provided with through holes, the hole walls of the through holes are provided with pressure spring sheets for pressing the conductive needle, and the anti-drop rod is abutted above the adjacent pressure spring sheets.

[0014] By adopting the above technical solution, when the conductive pin is inserted into the plug-in slot, the upper and lower pressing springs in the terminal block are squeezed by the conductive pin and deformed, thereby pressing the conductive pin tightly, making it more difficult for the conductive pin to fall out of the plug-in slot. The setting of the pressing spring can not only further clamp the conductive pin, but also transmit the pressure of the contact spring on the anti-drop rod to the conductive pin, thereby further improving the stability of the conductive pin when it is inserted into the terminal block.

[0015] Optionally, a connecting hole is opened on the bottom wall of the give way hole, a push rod is fixed to the lower side of the pressure spring sheet located below in the wiring terminal, a driving spring sheet abutting against the push rod is arranged on the hole wall of the connecting hole, a driving rod is fixed on the lower side of the driving spring sheet, and the driving rod is abutted against the pressure spring sheet located below it.

[0016] By adopting the above technical solution, after the terminal blocks in the upper row of the clearance hole group are pressed by the anti-drop rod, the pressure will be transmitted to the terminal blocks in the lower row of the clearance hole group through the push rod, the driving spring and the driving rod in sequence, thereby improving the plug-in stability between the terminal blocks in the lower row and the conductive pins.

[0017] Optionally, a positioning groove for the terminal seat to extend horizontally is formed on the needle seat. When the terminal seat extends into the positioning groove, a heat dissipation gap that is interconnected with the connecting hole is formed between the bottom of the terminal seat and the needle seat.

[0018] By adopting the above technical solution, the heat generated by the conductive pins and the wiring terminals during operation can be transferred to the heat dissipation gap through the connecting holes, which helps to improve the heat dissipation performance of the connector.

[0019] Optionally, the bracket includes a mounting plate detachably disposed on the needle seat, a vertical rod fixed above the mounting plate, and a horizontal rod fixed to one side of the vertical rod. The upper side of the mounting plate is provided with connecting blocks at both ends thereof, and the connecting blocks of two adjacent mounting plates are detachably connected by fasteners.

[0020] By adopting the above technical solution, since the mounting plate can be detachably arranged on the needle seat, in actual application, different numbers of anti-dropout components can be installed according to the number of wiring terminals in each row of the yield hole group, so that the wiring terminals in the upper row can correspond to an anti-dropout rod respectively, which is highly practical. Two adjacent groups of anti-dropout components can be connected by fasteners, which helps to improve the overall linkage of the anti-dropout components.

[0021] Optionally, the fixing plate is provided with a plurality of adjustment slots extending along the insertion direction of the conductive needles, an adjustment bolt is rotatably arranged in the adjustment slot, and the top end of the anti-drop rod is slidably arranged in the adjustment slot and is threadedly connected to the adjustment bolt.

[0022] By adopting the above technical solution, when the adjusting bolt is rotated, if the adjusting bolt is controlled not to move in the horizontal direction, the anti-dropping rod will be forced to move horizontally along the adjusting slot to adjust the position of the anti-dropping rod, thereby adapting to the anti-dropping slots in different horizontal directions. When assembling the anti-dropping assembly, the operator does not need to accurately control the position of the anti-dropping rod, and the assembly is convenient.

[0023] Optionally, the anti-slip rod includes an adjustment part and an anti-slip part integrally formed on the lower side of the adjustment part, the adjustment part is slidably arranged in the adjustment groove, the longitudinal sections of the adjustment part and the adjustment groove are both trapezoidal, and the upper side of the trapezoid is longer than the lower side.

[0024] By adopting the above technical solution, since the longitudinal sections of the anti-slip part and the anti-slip groove are both trapezoidal, the cooperation of the two can play a guiding and limiting role when the anti-slip rod moves, so that the anti-slip rod can only move horizontally but not vertically, and the movement stability of the anti-slip rod is high.

[0025] Optionally, the adjusting bolt is a butterfly bolt and one end away from the bolt head is threadedly connected with an adjusting nut, and the adjusting nut is attached to a side of the fixing plate away from the bolt head.

[0026] By adopting the above technical solution, when adjusting the horizontal position of the anti-drop rod, the operator can turn the adjusting bolt by hand, which is easy to operate. The adjusting nut and the bolt head of the adjusting bolt are arranged on both sides of the fixing plate, which plays a role in preventing the adjusting bolt from moving horizontally relative to the fixing plate.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. After the conductive pin is inserted into the terminal, the anti-dropout rod can be vertically extended into the corresponding anti-dropout groove to prevent the relative movement between the pin seat and the terminal seat. The conductive pin and the terminal are firmly connected, and the conductive stability of the connector is high;

[0029] 2. When the anti-drop rod is extended into the anti-drop groove, the contact spring can drive the anti-drop rod to contact the pressing spring sheet of the upper row of wiring terminals, so that the pressing spring sheet of the upper row of wiring terminals presses the conductive pin inserted therein; the pressure is transmitted to the lower row of wiring terminals through the push rod, the driving spring sheet and the driving rod in sequence, so that the pressing spring sheet of the lower row of wiring terminals presses the conductive pin inserted therein;

[0030] 3. The adjusting bolt can drive the anti-drop rod to move horizontally along the adjusting slot, thereby fine-tuning the position of the anti-drop rod to adapt to the anti-drop slots in different horizontal positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figures 1-5 This application is described in further detail.

[0039] An embodiment of the present application discloses a connector for an automobile.

[0040] Referring to Figure 1 and Figure 2 , the connector for an automobile includes a terminal block 1, a wiring terminal 2 arranged in the terminal block 1, a pin block 3, and a conductive pin 4 arranged in the pin block 3. The terminal block 1 is inserted horizontally on the pin block 3, and the conductive pin 4 is inserted horizontally on an adjacent wiring terminal 2. The horizontal, vertical, up, down and other orientations in this embodiment are orientations defined for the convenience of description based on the perspective of the attached drawings, and are not the absolute orientations of each component.

[0041] Referring to Figure 1 and Figure 2 , a horizontally extending positioning groove 31 is formed on the side of the pin block 3 facing the terminal block 1. The positioning groove 31 is used for the horizontal insertion of the terminal block 1 to realize the horizontal insertion of the pin block 3 and the terminal block 1. To improve the heat dissipation performance of the connector, a through groove is formed in the middle of the bottom wall of the positioning groove 31, so that when the terminal block 1 extends into the positioning groove 31, a heat dissipation gap 5 can be formed between the bottom of the terminal block 1 and the pin block 3 for ventilation and heat dissipation.

[0042] Referring to Figure 1 and Figure 2 , two rows of relief hole groups are distributed vertically on the terminal block 1. Each row of relief hole groups is horizontally distributed with a plurality of relief holes 11. The relief holes 11 extend horizontally along the insertion direction of the pin block 3 and the terminal block 1, and a wiring terminal 2 is embedded in each relief hole 11. Correspondingly, two rows of conductive components are also distributed vertically on the pin block 3. Each row of conductive components includes a plurality of conductive pins 4 for conduction. The number of conductive pins 4 in one row of conductive components is equal to the number of relief holes 11 in one row of relief hole groups, so that the conductive pins 4 and the wiring terminals 2 can correspond one by one. Specifically, the conductive pin 4 in this embodiment is bent and one end horizontally penetrates the pin block 3 and the other end vertically penetrates the pin block 3. One end of the conductive pin 4 horizontally penetrating the pin block 3 is inserted and connected to the wiring terminal 2.

[0043] Referring to Figure 3 and Figure 4 , a plugging groove 21 is formed on the end face of the wiring terminal 2 facing the pin block 3 for the horizontal insertion of the conductive pin 4. To improve the plugging stability of the conductive pin 4 and the wiring terminal 2, through holes 22 are respectively formed on the upper and lower groove walls of the plugging groove 21. A pressing elastic piece 23 is integrally formed on the hole wall of the through hole 22 far from the conductive pin 4. The upper and lower pressing elastic pieces 23 in the same wiring terminal 2 are bent towards each other to form a pressing part 231. When the conductive pin 4 extends into the plugging groove 21, the pressing part 231 abuts against the conductive pin 4, so that the conductive pin 4 is not easily separated from the wiring terminal 2.

[0044] Referring toFigure 2 , Figure 4 , multiple groups of anti-slip components 6 are arranged on the needle seat 3 to prevent the conductive needle 4 from slipping out of the terminal 2. In this embodiment, three groups of anti-slip components 6 are arranged in the horizontal direction to illustrate its structure. Each group of anti-slip components 6 includes a bracket 61, a connecting rod 62 vertically slidably inserted into the bracket 61, a fixing plate 63 arranged below the connecting rod 62, and multiple anti-slip rods 64 slidably arranged below the fixing rod. The distribution direction of the multiple anti-slip rods 64 is parallel to the distribution direction of the clearance holes 11.

[0045] Reference Figure 4 The bracket 61 includes a mounting plate 611 detachably mounted on the needle seat 3, a vertical rod 612 fixed on the upper side of the mounting plate 611, and a horizontal rod 613 fixed on the vertical rod 612 facing the terminal seat 1. The connecting rod 62 is slidably inserted into the horizontal rod 613. In order to prevent the connecting rod 62 from slipping off the horizontal rod 613, the connecting rod 62 in this embodiment includes two sections of vertically distributed cylinders, wherein the diameter of the cylinder located at the top is larger than the diameter of the cylinder located at the bottom, and a through hole is provided on the horizontal rod 613 through which only the lower cylinder can pass. The outer side of the connecting rod 62 is sleeved with an abutment spring 65 for driving the fixing plate 63 to move toward the terminal seat 1, and the telescopic direction of the abutment spring 65 is parallel to the vertical direction.

[0046] Reference Figure 4 , the upper side of each mounting plate 611 is respectively fixed with a connecting block 614 at both ends thereof, and the connecting blocks 614 in two adjacent mounting plates 611 are detachably connected by a fastener 615. The fastener 615 in this embodiment includes a fastening bolt and a fastening nut with threaded matching. In other embodiments, the fastener 615 can also be set as a block structure, and any method that can achieve detachable connection between the mounting plate 611 and the needle seat 3 is acceptable. During actual assembly, the mounting plate 611 can be threadedly connected to the needle seat 3 by the mounting bolt.

[0047] Reference Figure 4 , Figure 5 , the upper end surface of the terminal block 1 is provided with a plurality of vertically extending anti-slip grooves 12, the number of the anti-slip grooves 12 is the same as the number of the make way holes 11 in each row of the make way hole group, each anti-slip groove 12 is respectively connected to each make way hole 11 in the upper row of the make way hole group, and the spacing between two adjacent anti-slip grooves 12 is equal to the spacing between two adjacent anti-slip rods 64. After the needle seat 3 and the terminal block 1, the conductive needle 4 and the connecting terminal 2 are plugged into place, each anti-slip rod 64 will extend into the adjacent anti-slip groove 12 under the action of the corresponding abutment spring 65 to prevent the needle seat 3 and the terminal block 1 from moving in the opposite direction, so that the conductive needle 4 is not easily separated from the connecting terminal 2. At this time, the anti-slip rod 64 abuts against the pressing spring sheet 23 located above the upper row of the connecting terminal 2, so that the pressing spring sheet 23 can further press the conductive needle 4.

[0048] Reference Figure 4 ,Figure 5 A vertically penetrating communication hole 13 is provided on the bottom wall of the clearance hole 11, a push rod 24 is fixed to the lower side of the pressing spring sheet 23 located at the bottom of the terminal 2, and a driving spring sheet 14 is fixed to the hole wall of the communication hole 13 near the conductive needle 4. The driving spring sheet 14 is abutted below the push rod 24 to transmit the pressure of the pressing spring sheet 23 in the upper row of the terminal 2 downward. A driving rod 15 is fixed to the lower side of the driving spring sheet 14, and the driving rod 15 is abutted against the pressing spring sheet 23 located below it, so that the pressing spring sheet 23 in the lower row of the terminal 2 can also further press the conductive needle 4.

[0049] Reference Figure 4 , Figure 5 In order to match the anti-slip grooves 12 with different horizontal orientations, an adjustment groove 631 with an open lower end is provided on each fixed plate 63. The adjustment groove 631 extends horizontally in a direction parallel to the plugging direction of the conductive pin 4. An adjustment bolt 7 is rotatably arranged in the adjustment groove 631. Specifically, the adjustment bolt 7 is a butterfly bolt and is threadedly connected with an adjustment nut 8. The adjustment nut 8 is attached to the side of the fixed plate 63 away from the bolt head of the adjustment bolt 7 to limit the horizontal movement of the fixed plate 63 relative to the adjustment bolt 7. It should be noted that when the adjustment nut 8 is screwed, in order to ensure that the adjustment bolt 7 can rotate relative to the fixed plate 63, the adjustment nut 8 should not be screwed too tight.

[0050] Reference Figure 5 The anti-slip rod 64 includes an integrally formed adjustment portion 641 and an anti-slip portion 642. The anti-slip portion 642 is located at the lower side of the adjustment portion 641, and the adjustment portion 641 is slidably arranged in the adjustment slot 631. In order to prevent the anti-slip rod 64 from detaching from the fixed plate 63, the longitudinal sections of the adjustment portion 641 and the adjustment slot 631 in this embodiment are both trapezoidal, and the upper side of the trapezoid is longer than the lower side. In other embodiments, the trapezoid can also be set to other shapes. When the adjusting bolt 7 is rotated, the anti-slip rod 64 will move horizontally along the adjustment slot 631, thereby changing the horizontal position of the anti-slip rod 64 to adapt to the anti-slip slots 12 in different horizontal orientations.

[0051] The implementation principle of the automotive connector of the embodiment of the present application is as follows: when the conductive pin 4 is inserted into the terminal 2, the terminal seat 1 is embedded in the positioning groove 31, and each anti-slip rod 64 will pass through the anti-slip groove 12 and abut against the adjacent pressing spring 23 under the drive of the corresponding abutting spring 65, so that the upper row of terminal 2 presses the conductive pin 4 inserted therein; at the same time, the above-mentioned force will be transmitted to the lower row of terminal 2 through the push rod 24, the driving spring 14 and the driving rod 15 in sequence, so that the lower row of terminal 2 presses the conductive pin 4 inserted therein. In this way, the anti-slip rod 64 can not only prevent the terminal seat 1 and the needle seat 3 from moving in opposite directions, but also improve the plugging reliability of the conductive pin 4 and the terminal 2, which helps to ensure the conductive performance of the connector.

[0052] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
