[0023] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0024] This embodiment provides a magnetic combined female terminal, such as Figures 1 to 3 As shown, it includes a plug-in portion 1 for plugging with a male terminal, a connecting portion 2 for connecting with a cable, and a magnetic attraction component 3 connecting the plug-in portion 1 and the connecting portion 2, and the magnetic attraction component 3 includes a magnetic member 301 and a positioning pin 302, one of which is arranged on the connecting portion 2, and the other is relatively arranged on the plug-in portion 1. The magnetic member 301 has a ring structure, and at least a part of the positioning pin 302 is inserted into the ring structure to attract the magnetic member 301, so as to connect the plug-in portion 1 and the connecting portion 2.

[0025] In this embodiment, the magnetic member 301 and the positioning pin 302 are both coaxially arranged with the female terminal. The magnetic member 301 is a magnet. The magnetic member 301 can be arranged on the connecting portion 2 and extend along the axial direction of the female terminal to be in the shape of a column having a ring structure, so that the magnetic contact area between the magnetic member 301 and the positioning pin 302 can be increased. The positioning pin 302 can be arranged on the plug-in portion 1 and extend along the axial direction of the female terminal and also be in the shape of a column. In actual use, the positioning pin 302 is inserted into the ring structure of the magnetic member 301 along the axial direction of the female terminal, and the plug-in portion 1 and the connecting portion 2 are connected to complete the assembly of the female terminal. Or the positioning pin 302 is pulled out from the ring structure of the magnetic member 301 along the axial direction of the female terminal, and the plug-in portion 1 and the connecting portion 2 are separated to complete the disassembly of the female terminal.

[0026] It should be understood that, in other embodiments, the magnetic member 301 may also be disposed on the plug-in portion 1 , and the positioning pin 302 may be disposed on the connecting portion 2 . This may be designed according to actual needs and is not limited here.

[0027] Through the above technical solution, by setting a magnetic attraction part between the plug-in part 1 and the connecting part 2, the positioning pin 302 is inserted into the ring structure of the magnetic part 301 to connect the plug-in part 1 and the connecting part 2. When the plug-in part 1 needs to be replaced, the positioning pin 302 only needs to be pulled out from the ring structure of the magnetic part 301. Through the above operation, the female terminal can be quickly connected and disassembled, which is easy to operate and improves work efficiency. It solves the problem that the female terminal can only be replaced as a whole after being worn, resulting in a large use and maintenance cost and reduced economic benefits.

[0028] In some embodiments, reference Figure 1 and Figure 2 A first mounting hole 201 is provided on the end surface of the first end of the connecting portion 2, and at least a portion of the magnetic member 301 is disposed in the first mounting hole 201. A second mounting hole is provided on the end surface of the first end of the plug-in portion 1, and a positioning pin 302 is disposed in the second mounting hole, and at least a portion of the positioning pin 302 protrudes from the end surface of the first end of the plug-in portion 1. The provision of the first mounting hole 201 and the second mounting hole enables the magnetic member 301 and the connecting portion 2, and the positioning pin 302 and the plug-in portion 1 to be tightly connected in assembly, providing a reliable and stable fit, and improving the reliability of the device.

[0029] In some embodiments, Figure 1 As shown, the magnetic attraction assembly 3 also includes a baffle 303, which is located between the connecting portion 2 and the plug-in portion 1 and is arranged on the end surface of the first end of the connecting portion 2 to block the magnetic member 301 in the first mounting hole 201. The baffle 303 is provided with a through hole 3031 for the positioning pin 302 to be inserted into the magnetic member 301, and the diameter of the through hole 3031 is larger than the diameter of the positioning pin 302 and smaller than the outer diameter of the magnetic member 301. By arranging the baffle 303 on the end surface of the first end of the connecting portion 2, it is possible to prevent the magnetic member 301 from being pulled out of the first mounting hole 201 during the plugging and unplugging process, thereby further improving the reliability of the device.

[0030] In some embodiments, reference Figure 1 and Figure 2 , a countersunk hole 202 is also provided on the end surface of the first end of the connecting part 2, a baffle 303 is arranged in the countersunk hole 202 and connected to the connecting part 2, and the end surface of the baffle 303 facing the plug-in part 1 is flush with the end surface of the first end of the connecting part 2. This arrangement is equivalent to increasing the contact area between the end surface of the first end of the connecting part 2 and the end surface of the first end of the plug-in part 1, which can maintain a high connection stability, make the connection more firm, and not easily deformed, and also improve the overall rigidity of the female terminal.

[0031] In some embodiments, reference Figure 1 and Figure 2The female terminal further includes a fixing assembly, which includes a locking member 4. The locking member 4 penetrates the plug-in portion 1 along the axial direction of the female terminal and is inserted into the connecting portion 2 to lock and fix the connecting portion 2 with the plug-in portion 1. The setting of the locking member 4 further improves the connection strength between the connecting portion 2 and the plug-in portion 1, avoids the separation of the connecting portion 2 and the plug-in portion 1, and further improves the reliability of the device.

[0032] In some embodiments, at least two locking members 4 are provided, and the locking members 4 are evenly distributed around the magnetic attraction assembly 3. This arrangement can keep the plug-in portion 1 and the connecting portion 2 tight and not loose, and the force is evenly applied, and the connection will not be deformed; at the same time, the connection strength between the connecting portion 2 and the plug-in portion 1 is further improved.

[0033] In some embodiments, the locking member 4 is a screw. The screw has a low screwing torque and a high locking performance, and is easy to install and fast to install. It can complete the tightening and anti-loosening effects by itself, thereby improving work efficiency. It is also easy to maintain and replace, thereby improving economic benefits.

[0034] In some embodiments, reference Figure 1 and Figure 2 The fixing assembly also includes a connecting disk 5 coaxially arranged with the female terminal. The connecting disk 5 is arranged on the side of the positioning pin 302 away from the magnetic member 301 and is located in the plug-in portion 1. The locking member 4 sequentially penetrates the connecting disk 5, the first end of the plug-in portion 1 and the baffle 303 and then is inserted into the first end of the connecting portion 2 to lock and fix the connecting portion 2 and the plug-in portion 1. The connecting disk 5 is equivalent to the role of a gasket, which can prevent the locking member 4 from causing damage to the plug-in portion 1 of the female terminal during installation and removal. Moreover, since the contact area between the locking member 4 and the plug-in portion 1 is small, the force is also small, and it is easy to loosen. In order to make the locking of the locking member 4 more secure, the connecting disk 5 is provided to increase the contact area of ​​the locking member 4, and at the same time, it can also make the force area more balanced.

[0035] In some embodiments, Figure 3 As shown, the end of the positioning pin 302 facing the magnetic member 301 is provided with a rounded corner 3021. In this way, the radial dimension of the end of the positioning pin 302 is reduced, making it easier to insert into the ring structure of the magnetic member 301, and also playing a certain guiding role, improving the assembly efficiency. At the same time, the end edge of the positioning pin 302 is smoother, which can reduce scratches and wear during the insertion of the magnetic member 301, thereby increasing the service life of the magnetic member 301.

[0036] In some embodiments, the surface of the magnetic member 301 is provided with a metal conductive layer by electroplating. By electroplating, the metal conductive layer can be stably fixed on the outer surface of the magnetic member 301, and the structure is extremely strong, which improves the reliability of the device. Moreover, in this way, the magnetic member 301 can have the ability of magnetic attraction and can also realize the function of conducting electricity through the metal conductive layer, achieving dual functions and being easy to use.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present disclosure.

[0038] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is also intended to include these modifications and variations.
