Description

A female connector Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a female connector. Background Art

[0002] As cars develop towards new energy and autonomous driving features, automotive electronic systems are becoming increasingly complex, lightweight, and integrated. Consequently, the number of PCBs within an electronic module is increasing. To connect PCBs, two PCBs need to be connected together using connectors. PCB connectors consist of male and female connectors. The male connector is fixed to one PCB, and the female connector is fixed to the other. The male and female connectors mate to connect the two PCBs.

[0003] The existing female connector consists of a female body and female terminals. The female body is provided with several snap-in grooves, and the female terminals are provided with several snap-in grooves. The female terminals are snap-fitted and fixed in the corresponding snap-in grooves, and the ends of the female terminals are welded and fixed on the PCB board. The female connector is plugged into the male connector so that the outer wall of the female terminal is in point contact with the side wall of the male terminal, thereby realizing the connection between the two PCB boards.

[0004] The above-mentioned female terminal and male terminal are connected to the PCB board through point contact. This point contact method may cause connection failure when dust or other foreign matter that affects contact reliability exists between the terminals, and there is room for improvement.

[0005] Summary of the Invention

[0006] In order to reduce the possibility of connection failure between the terminals of the male connector and the terminals of the female connector due to dust and other factors, and to improve the stability of the connection between the male connector and the female connector, the present application provides a female connector.

[0007] This application provides a female connector, which adopts the following technical solution:

[0008] A female connector includes a female body and several female terminals arranged on the female body, the female terminal includes a fixing portion, a holding portion fixed on the fixing portion, and a contact portion fixed on the holding portion away from one end of the fixing portion, the fixing portion is fixedly connected to the PCB board, the holding portion is fixedly connected to the female body, the contact portion is arranged at an inclined angle to the holding portion, the contact portion is bent, and several contact points are arranged on the side wall of the contact portion.

[0009] By adopting the above technical solution, the fixing part is welded and fixed on the PCB board, and the female end body is fixed on the PCB board with the support of the female terminal. The setting of the holding part makes the connection between the female terminal and the female end body more stable. The staff plugs the female end body into the male connector so that the contact part contacts the terminal on the male connector. Multiple contact points are set on the contact part so that the contact part contacts the terminal on the male connector at multiple points. When one of the contact points is affected and the connection between the male connector and the female connector fails, the other contact points come into play, reducing the impact of external factors such as dust on the connection between the male connector and the female connector.

[0010] Optionally, a plurality of separation grooves are provided on the side wall of the contact portion, and a plurality of the contact points are separated by the separation grooves.

[0011] By adopting the above technical solution, the separation groove is opened so that the contact portion is arranged in strips, which reduces the connector resistance between the male and female connectors and reduces the possibility of interference between adjacent contact points, thereby improving the reliability of contact between the male connector and the female connector.

[0012] Optionally, a through hole is formed through the side wall of the contact portion, the inner wall of the through hole is arc-shaped, and the contact points are distributed on the periphery of the through hole.

[0013] By adopting the above technical solution, the opening of the through hole facilitates the setting of more contact points. The through hole is opened in an arc shape, so that the positions of the contact points in the vertical direction on the contact part are different, which makes it easier for the contact points to abut against different positions on the male connector, thereby making the connection between the male connector and the female connector more reliable.

[0014] Optionally, a bent portion is fixed to one end of the contact portion away from the fixing portion, and an end portion of the bent portion abuts against an inner wall of the female end body.

[0015] By adopting the above technical solution, the female connector is plugged into the male connector, and the setting of the bent portion makes the contact portion tend to be toward the outer wall of the male connector terminal, thereby making the connection between the male connector and the female connector more stable.

[0016] Optionally, a driving rod is rotatably connected to the female end body, a roller is fixed on the outer wall of the driving rod, an elastic member is provided between the driving rod and the female terminal, the elastic member is used to connect the driving rod and the female terminal, and drives the roller to rotate during the process of plugging the female end body onto the male end connector, and the end of the elastic member away from the driving rod is connected between the fixed portion and the contact portion.

[0017] By adopting the above technical solution, when inserting the female connector into the male connector, the roller rolls on the inner wall of the male connector, the roller drives the driving rod to rotate, and the elastic member pulls the female terminal, causing the female terminal to tend to move away from the outer wall of the terminal of the male connector, thereby reducing the friction between the female terminal and the terminal on the male connector. After the female connector is fully inserted into the male connector, the female terminal rebounds under the action of the elastic member's own rebound force, thereby making the connection between the male connector and the female connector more stable. When the female connector needs to be separated from the male connector, the female connector is pulled out in a direction away from the male connector, and the female terminal is separated from the terminal of the male connector under the action of the elastic member, thereby reducing friction.

[0018] Optionally, a sliding groove is provided on the female end body, and the driving rod slides in the sliding groove, and the driving rod can rotate in the sliding groove.

[0019] By adopting the above technical solution, the provision of the sliding groove makes the movement of the driving rod more flexible, reducing the possibility of poor contact between the female terminal and the terminal of the male connector due to the traction of the driving rod.

[0020] Optionally, a mounting hole is provided on the side wall of the female end body, a driving block is slidably connected to the inner wall of the mounting hole, a clamping piece is provided on the driving block, the end of the clamping piece can abut against the outer wall of the female terminal, and the end of the driving block facing away from the clamping piece extends beyond the side wall of the female end body.

[0021] By adopting the above technical solution, during the process of plugging the female terminal into the male connector, the driving block slides on the inner wall of the male connector. After the female connector is plugged into the male connector, the driving block is pressed into the mounting hole, and the fastening member is compressed, exerting force on the outer wall of the female terminal, thereby ensuring good contact between the female terminal and the terminal on the male connector, reducing the possibility of connection failure.

[0022] Optionally, a plurality of reinforcement blocks are fixed on the side wall of the holding portion, and the reinforcement blocks are all fixedly connected to the female end body.

[0023] By adopting the above technical solution, the holding part is fixedly connected to the female body, and the strengthening device limits the sliding of the holding part, thereby making the connection between the holding part and the female body more stable and reducing the possibility of looseness between the holding part and the female body.

[0024] Optionally, a wiping portion is fixed on the inner wall of the female end body, and the wiping portion can contact the side wall of the terminal of the male end connector.

[0025] By adopting the above technical solution, during the process of plugging the female connector into the male connector, the wiping portion slides along the outer wall of the terminal on the male connector, cleaning dust and other impurities on the outer wall of the terminal of the male connector, thereby reducing the possibility of dust and other impurities affecting the connection between the female terminal and the terminal of the male connector.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Several contact points are set on the contact part. After the female terminal is plugged into the male connector, the female terminal contacts the outer wall of the male connector terminal at multiple points, avoiding the possibility of failure of the connection between the male connector and the female connector due to single point contact.

[0028] 2. The opening of the separation groove reduces the connector resistance between the male and female connectors, while reducing the possibility of mutual interference between the contact points, thereby making the connection between the male connector and the female connector more stable.

[0029] 3. The wiping part cleans the dust on the outer wall of the male connector terminal, thereby reducing the possibility of dust being stuck between the female terminal and the outer wall of the male connector terminal, thereby reducing the possibility of affecting the connection between the male connector and the female connector.

DETAILED DESCRIPTION

[0037] The present application is further described in detail below with reference to Figures 1-6.

[0038] An embodiment of the present application discloses a female connector.

[0039] Example 1

[0040] Referring to Figure 1, a female connector includes a female body 1 and several female terminals 2 arranged on the female body 1. When the staff inserts the female connector into the male connector, the female body 1 drives the female terminals 2 to move, so that the female terminals 2 contact with the terminals on the male connector, thereby realizing the connection between the two PCB boards.

[0041] 2 , the female terminal 2 includes a fixing portion 3, a holding portion 4 integrally fixed to the end of the fixing portion 3, and a contact portion 5 integrally fixed to the end of the holding portion 4 away from the fixing portion 3. The contact portion 5 is curved, and a plurality of contact points 6 are provided on the side wall of the contact portion 5. In this application, two contact points 6 are preferably provided. A separation groove 7 is provided through the side wall of the contact portion 5, and the separation groove 7 extends to the end of the contact portion 5 away from the holding portion 4. The opening of the separation groove 7 separates the contact points 6 on the contact portion 5. After the female terminal 2 is plugged into the male connector, the two contact points 6 on the contact portion 5 are both in contact with the side wall of the terminal of the male connector, thereby avoiding interference with the contact between the female terminal 2 and the terminal on the male connector due to failure of one of the contact points 6.

[0042] 2 , the separation groove 7 provides elasticity to the contact portions 5 on both sides, thereby reducing mutual interference between the two contact points 6 and the connector resistance between the male and female connectors, thereby making the connector more sensitive.

[0043] Referring to Figure 2, the fixing portion 3 is fixed to the side wall of the PCB board by welding, and a plurality of fixing grooves are provided on the side wall of the female end body 1. The holding portion 4 is fixed to the inner wall of the fixing groove by injection molding. A plurality of reinforcing blocks 17 are integrally fixed to the outer wall of the holding portion 4. The provision of the reinforcing blocks 17 increases the contact area between the holding portion 4 and the female end body 1, limits the relative sliding between the female end body 1 and the holding portion 4, and thus makes the connection between the holding portion 4 and the female end body 1 more stable.

[0044] In the first embodiment of the present application, the implementation principle of a female connector is as follows: the female connector is inserted into the male connector, and the two contact points 6 on the female terminal 2 are both in contact with the side wall of the male connector terminal to realize the connection between the male connector and the female connector. The setting of the two contact points 6 reduces the possibility of affecting the connection between the PCB boards after the contact between one of the contact points 6 and the outer wall of the terminal of the male connector is affected.

[0045] Example 2

[0046] The second embodiment differs from the first embodiment in that: referring to Figure 3, a through hole 8 is provided on the side wall of the contact portion 5, the inner wall of the through hole 8 is arc-shaped, and a number of contact points 6 are distributed on the periphery of the through hole 8. After the female terminal 2 is plugged into the male connector, the contact points 6 all abut against the side wall of the terminal on the male connector. Multiple contact points 6 are set at different positions, so that the contact between the female terminal 2 and the terminal of the male connector is more stable.

[0047] The implementation principle of the second embodiment is the same as that of the first embodiment.

[0048] Example 3

[0049] Embodiment 3 is different from embodiment 1 in that: referring to Figures 2 and 4, a sliding groove 13 is provided on the female end body 1, and a driving rod 10 is slidingly connected to the inner wall of the sliding groove 13. The driving rod 10 can rotate in the sliding groove 13, and a roller 11 is coaxially fixed on the outer wall of the driving rod 10. An elastic member 12 is provided between the driving rod 10 and the female terminal 2. In this application, the elastic member 12 is preferably a torsion spring. One end of the elastic member 12 is fixedly connected to the outer wall of the driving rod 10, and the other end is fixedly connected to the position between the holding portion 4 and the contact portion 5.

[0050] 2 and 4 , during the process of inserting the female terminal 2 onto the male connector, the roller 11 rolls on the inner wall of the male connector, driving the driving rod 10 to roll, and the end of the elastic member 12 wraps around the outer wall of the driving rod 10, pulling the outer wall of the female terminal 2, so that the female terminal 2 has a tendency to face away from the outer wall of the terminal of the male connector, thereby reducing the possibility of friction between the female terminal 2 and the outer wall of the terminal of the male connector generating debris during the process of inserting the female connector onto the male connector. After the female connector is inserted into the male connector, the elastic member 12's own rebound force causes the roller 11 and the support rod to return to their original positions, so that the female terminal 2 abuts against the outer wall of the terminal of the male connector, thereby achieving the connection between the male connector and the female connector.

[0051] 2 and 4 , when the female connector needs to be unplugged, the female connector is pulled away from the male connector, and the roller 11 rolls. Under the traction of the elastic member 12, the female terminal 2 tends to face away from the outer wall of the terminal on the male connector, thereby reducing the friction between the female terminal 2 and the outer wall of the terminal of the male connector.

[0052] Embodiment 3, the implementation principle of a female connector is: in the process of plugging the female connector into the male connector, the roller 11 is driven to roll, and the roller 11 drives the driving rod 10 to rotate, and under the action of the elastic member 12, the female terminal 2 moves in a direction away from the outer wall of the terminal on the male connector, reducing the friction between the female terminal 2 and the outer wall of the terminal on the male connector, so that the female connector and the male connector are reliably connected while reducing the wear caused by abutment slippage.

[0053] Example 4

[0054] Embodiment 4 is different from embodiment 1 in that: referring to Figures 5 and 6, a bent portion 9 is integrally fixed to the end of the contact portion 5 facing away from the retaining portion 4, and the outer wall of the bent portion 9 abuts against the inner wall of the female end body 1. The inner wall of the female end body 1 applies a force on the bent portion 9 toward the outer wall of the male connector terminal. After the female connector is plugged into the male connector, the contact point 6 abuts against the outer wall of the male connector terminal under the restriction of the bent portion 9, making the connection between the male connector and the female connector more stable.

[0055] 6 , a mounting hole 14 is provided on the side wall of the female end body 1, and a driving block 15 is slidably connected to the inner wall of the mounting hole 14, and a clamping member is provided on the side wall of the driving block 15. In this application, a spring is preferably used as the clamping member, and one end of the clamping member is fixedly connected to the inner wall of the mounting hole 14, and the other end is fixedly connected to the outer wall of the driving block 15. The outer wall of the driving block 15 can contact the inner wall of the female end body 1. The clamping member is compressed during the process of plugging the female end connector onto the male end connector. After the male end connector is fully plugged into the female end connector, the contact portion 5 is limited by the joint action of the inner wall of the male end connector and the clamping member, so that the connection between the contact portion 5 and the terminal of the male end connector is more stable.

[0056] Referring to Figure 5, a wiping portion 18 is fixed on the outer wall of the female terminal 2, and the wiping portion 18 is located near the contact portion 5. In this application, the wiping portion 18 is preferably made of polyester fiber material. During the process of plugging the female connector into the male connector, the wiping portion 18 contacts the outer wall of the terminal on the male connector, and wipes dust and other particles on the outer wall of the terminal of the male connector, thereby reducing the possibility of interference with the contact between the female terminal 2 and the terminal of the male connector.

[0057] In the fourth embodiment of the present application, the implementation principle of a female connector is as follows: the female connector is inserted into the male connector, the wiping portion 18 wipes the dust on the outer wall of the terminal of the male connector, and after the female connector is inserted into the male connector, the outer wall of the contact portion 5 is abutted against the outer wall of the terminal of the male connector under the joint action of the driving block 15 and the bending portion 9, thereby making the connection between the male connector and the female connector more stable and reducing the possibility of failure of the floating connector.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
