[0043] In the embodiments of the present application, unless otherwise clearly specified and limited, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0044] According to the embodiments of the first aspect of the present application, as shown in Figures 1 - 4 the plug 1 provided by the present application includes a plug body 101 and a male terminal module 102. Among them, the plug body 101 is provided with a plug interface 103 and a wiring port 104, and the plane where the plug interface 103 is located is perpendicular to the plane where the wiring port 104 is located; the male terminal module 102 includes a male terminal 105 and a wire pressing member 106 disposed in the plug body 101. The male terminal 105 is vertically connected to the wire pressing member 106, and the male terminal 105 extends in the direction of the plug interface 103; the wire pressing member 106 extends in the direction of the wiring port 104.

[0045] In this embodiment of the present application, it is intended to change the straight wire outlet direction of the traditional plug so that it can better meet the installation requirements of narrow spaces. Specifically:

[0046] The plug body 101 is the basic part of the entire plug 1, which contains a plug interface 103 for connecting to the socket 2 and a wiring port 104 for connecting wires. The special thing is that the planes where these two ports are located are perpendicular to each other. This design allows the wire to extend from the side rather than from the rear, thus reducing the space occupied by the plug 1 in the front-rear direction.

[0047] By arranging the insertion port 103 and the wiring port 104 on a vertical plane, the overall volume of the plug 1 can be reduced to a certain extent. And in some cases, the wire can bypass obstacles more naturally or closely adhere to the wall surface, etc., thus saving space. This is particularly important for application scenarios where wiring needs to be arranged in a narrow space.

[0048] The male terminal module 102 includes two parts: a male terminal 105 and a wire pressing member 106. The male terminal 105 is the part used to make physical contact with the female terminal 202 in the socket 2 and establish an electrical connection to achieve current transmission; while the wire pressing member 106 is the part used to fix the wire. A right-angle connection is formed between the male terminal 105 and the wire pressing member 106. Such a design can make the male terminal 105 face the direction of the insertion port 103, and at the same time, the wire pressing member 106 conveniently faces the direction of the wiring port 104, so that the plug 1 has an elbow design. Due to the elbow design, users can adjust the wire routing according to actual needs, avoiding the inconvenience that traditional plugs may bring.

[0049] Therefore, the plug provided by the embodiment of the present application can solve the problem of difficult wiring in a narrow space and improve the user experience.

[0050] According to an embodiment of the present application, as shown in Figures 1 - 4 the wire pressing member 106 includes: a first connecting portion 107 and a wire pressing portion 108. The first connecting portion 107 is vertically connected to the male terminal 105, and the first connecting portion 107 is detachably connected to the male terminal 105; the wire pressing portion 108 is connected to the first connecting portion 107, and the wire pressing portion 108 corresponds to the wiring port 104.

[0051] In this embodiment of the present application, the first connecting portion 107 of the wire pressing member 106 is connected to the male terminal 105 for the purpose of ensuring the stability of the current conduction path. It is worth mentioning that the first connecting portion 107 and the male terminal 105 are detachably connected, which means that the user can easily separate these two parts. The advantage of this design is that it simplifies the maintenance process. When it is necessary to replace or check components, the operation can be completed quickly and conveniently, reducing the maintenance cost.

[0052] The wire pressing portion 108 is connected to the first connecting portion 107 and corresponds to the wiring port 104 in position. Such a design is for the convenience of connecting the wire. The wire pressing portion 108 is provided with a wire clamping hole for fixing the wire to ensure the stable and reliable mechanical and electrical connection between the wire and the plug 1.

[0053] When connecting a wire is needed, first, the wire can be fixed through the wire pressing part 108, and then an electrical connection is established with the male terminal 105 through the first connecting part 107. If it is necessary to inspect or replace the wire or the connection part, simply disconnect the connection between the first connecting part 107 and the male terminal 105.

[0054] According to an embodiment of the present application, as shown in Figures 1 - 4 the male terminal 105 includes: a second connecting part 109 and a contact part 110. The second connecting part 109 is detachably connected to the first connecting part 107; the contact part 110 includes a plurality of elastic pieces 111, and the plurality of elastic pieces 111 are vertically distributed around the second connecting part 109 in a ring shape.

[0055] In this embodiment of the present application, the second connecting part 109 of the male terminal 105 and the first connecting part 107 of the wire pressing part 106 form a detachable connection. Such a design enables the male terminal 105 and the wire pressing part 106 to be easily separated, thus facilitating the maintenance or replacement of any one of the components. This modular design improves the flexibility and maintainability of the product.

[0056] For example, a threaded post 112 is provided at the bottom of the first connecting part 107 of the wire pressing part 106, and a threaded hole 113 is provided in the second connecting part 109 of the male terminal 105. The threaded post 112 is threadedly connected to the threaded hole 113, thereby realizing the detachable assembly of the first connecting part 107 and the second connecting part 109.

[0057] For another example, a clamping protrusion is provided at the bottom of the first connecting part 107 of the wire pressing part 106, and a clamping groove is provided in the second connecting part 109 of the male terminal 105. The clamping protrusion is clamped with the clamping groove, thereby realizing the detachable assembly of the first connecting part 107 and the second connecting part 109.

[0058] The contact part 110 includes a plurality of elastic pieces 111, and these elastic pieces 111 are vertically distributed around the second connecting part 109 in a ring shape. The design purpose of the elastic pieces 111 is to provide a better elastic contact effect, ensuring that the male terminal 105 can firmly engage with the female terminal 202 in the socket 2, thereby ensuring a stable electrical connection and reducing the risk of unstable power transmission caused by poor contact.

[0059] As Figures 1 - 5 shown, when the plug 1 is inserted into the socket 2, the plurality of elastic pieces 111 on the male terminal 105 will contact the female terminal 202 in the socket 2. Since the elastic pieces 111 have a certain elasticity, they will deform slightly when contacting, which can not only provide sufficient contact pressure to ensure a good electrical connection, but also maintain the reliability of the contact during multiple plugging and unplugging processes, extending the service life of the product.

[0060] In the embodiments of the present application, by introducing the detachable second connecting part 109 and the contact part 110 with multiple elastic pieces 111, not only the connection stability between the plug 1 and the socket 2 is improved, but also the maintenance convenience and durability of the product are increased. This design is particularly suitable for application scenarios that require frequent plugging and unplugging or have a relatively harsh working environment, and can effectively enhance the user experience and the overall performance of the product.

[0061] According to an embodiment of the present application, referring to Figure 1 and Figure 2 as shown, the number of male terminal modules 102 is two, and the two male terminal modules 102 are a positive male terminal module and a negative male terminal module respectively.

[0062] Specifically, the positive male terminal module is responsible for transmitting the positive current of the power supply, and the negative male terminal module is responsible for transmitting the negative current of the power supply.

[0063] According to an embodiment of the present application, referring to Figure 1 and Figure 2 as shown, the plug body 101 is detachably connected with an end cap 114. The end cap 114 is provided with a wiring port 104, and a first sealing ring (not shown in the figure) is arranged in the wiring port 104.

[0064] In this embodiment of the present application, the end cap 114 is designed to be detachably connected to the plug body 101, and such a design facilitates the installation and maintenance by the user. When connecting a wire, the user can first remove the end cap 114, and then reinstall the end cap 114 after completing the wire connection.

[0065] The wiring port 104 is located on the end cap 114 and is the part for accessing the wire. The existence of the wiring port 104 enables the wire to enter the interior of the plug 1 from a specific direction without interfering with the functions of other parts.

[0066] A first sealing ring is arranged in the wiring port 104. Its function is to provide a sealing layer after the wire passes through the wiring port 104 and is connected to the pressing part 108 of the wire pressing piece 106, preventing external substances such as moisture and dust from entering the interior of the plug 1 and protecting the internal electrical connection from the influence of the external environment.

[0067] The design of the first sealing ring can adapt to wires of different diameters, tightly wrap the wire through the elasticity of the material itself, and ensure good sealing even when the wire is pulled or vibrated. The use of the first sealing ring improves the protection level of the plug 1. Especially in outdoor or industrial environments, it can effectively prevent pollutants such as moisture and dust from entering the interior of the plug 1 and extends the service life of the plug 1.

[0068] By improving the sealing performance, the embodiments of the present application can ensure the normal operation of the device under various environmental conditions, reduce the maintenance frequency, and lower the failure rate.

[0069] According to an embodiment of the present application, referring to Figure 1 and Figure 2 As shown, on the outer wall of the plug body 101 adjacent to the socket interface 103, there is a receiving groove 115, and a second sealing ring (not shown in the figure) is provided in the receiving groove 115.

[0070] In this embodiment of the present application, the receiving groove 115 is located on the outer wall of the plug body 101 adjacent to the socket interface 103, and its position surrounds the edge of the socket interface 103. The second sealing ring is placed in the receiving groove 115, and its material can be rubber with a certain elasticity or other sealing materials, which can deform under external force, so as to fill the gap between the plug body 101 and the plug-in part 204 of the socket 2.

[0071] As Figure 1 and Figure 5 As shown, when the plug 1 is inserted into the socket 2, the second sealing ring will be squeezed and deformed and closely fit into the gap between the plug body 101 and the plug-in part 204 of the socket 2, forming a sealing barrier. This design of the sealing ring can effectively prevent external substances such as water and dust from entering the connection area between the plug 1 and the socket 2, thereby protecting the internal circuit from damage.

[0072] The use of the second sealing ring can significantly improve the protection level at the connection between the plug 1 and the socket 2. Especially in outdoor or industrial environments, this design can prevent moisture, dust, and other pollutants from entering, ensuring the reliability and durability of the electrical connection.

[0073] According to an embodiment of the present application, referring to Figure 1 and Figure 2 As shown, a pressing frame 116 is detachably connected to the socket interface 103 of the plug body 101, and the pressing frame 116 is used to press the second sealing ring into the receiving groove 115.

[0074] Specifically, the edge of the pressing frame 116 is provided with a bayonet 117, and the edge of the socket interface 103 is provided with a buckle 118, and the buckle 118 is clamped with the bayonet 117. Alternatively, the pressing frame 116 can also be connected to the socket interface 103 of the plug body 101 by screws.

[0075] When installing or replacing the second sealing ring, the user can first remove the pressing frame 116, put the new sealing ring into the receiving groove 115, and then install the pressing frame 116 back in place, and use the pressure of the pressing frame 116 to fix the sealing ring in place. This design makes the replacement of the sealing ring very simple and fast.

[0076] According to an embodiment of the present application, with reference to Figure 1 and Figure 2 As shown, a protective sleeve 119 is provided at a portion of the plug body 101 adjacent to the insertion interface 103, and there is an insertion cavity 120 between the protective sleeve 119 and a portion of the plug body 101. The insertion cavity 120 is used to plug into the socket 2.

[0077] In this embodiment of the present application, the protective sleeve 119 is located at a portion of the plug body 101 adjacent to the insertion interface 103. Its function is to provide additional physical protection for the plug 1 and also participate in the sealing process. The cavity formed between the protective sleeve 119 and the plug body 101 is used to accommodate the insertion portion 204 of the socket 2. When the plug 1 is inserted into the socket 2, the insertion portion 204 of the socket 2 will enter this insertion cavity 120. At this time, the second sealing ring will be compressed between the plug body 101 and the inner side of the insertion portion 204 of the socket 2 to form a first sealing barrier.

[0078] In addition to the seal provided by the second sealing ring, the protective sleeve 119 also contacts the outer side of the insertion portion 204 of the socket 2 to form a second seal. This double-sealing design can greatly improve the sealing performance at the connection between the plug 1 and the socket 2 and prevent external substances such as moisture and dust from intruding.

[0079] In the embodiment of the present application, through the design of combining the protective sleeve 119 with the second sealing ring, not only the sealing performance at the connection between the plug 1 and the socket 2 is improved, but also the overall physical protection ability of the plug 1 is enhanced. This double-sealing mechanism can better adapt to harsh working environments, extend the service life of the equipment, and reduce maintenance costs.

[0080] According to an embodiment of the present application, with reference to Figure 1 and Figure 2 As shown, the plug 1 further includes: a male terminal signal pin module 121. The male terminal signal pin module 121 is detachably connected inside the plug body 101 and corresponds to the insertion interface 103.

[0081] In this embodiment of the present application, the male terminal signal pin module 121 is a component that can be detachably connected to the plug body 101. Its main function is to provide the ability for signal transmission. This module contains multiple signal pins for plugging into the female terminal signal pin module 203 inside the socket 2, as Figure 5 shown.

[0082] The position of the male terminal signal pin module 121 corresponds to the insertion interface 103, ensuring that when the plug 1 is inserted into the socket 2, the male terminal signal pin module 121 can accurately dock with the female terminal signal pin module 203 inside the socket 2 to achieve signal transmission.

[0083] The connection between the common terminal signal pin module 121 and the plug body 101 is detachable, which means that users can easily replace different signal pin modules according to actual needs. This design improves the flexibility and adaptability of the plug 1.

[0084] According to an embodiment of the second aspect of the present application, with reference to Figure 6 As shown, the present application further provides a connector, including: a socket 2 and the plug 1 of the above embodiment, and the plug 1 is plugged and matched with the socket 2.

[0085] As Figure 5 As shown, the socket 2 includes a socket body 201, female terminals 202, and a female terminal signal pin module 203. The socket body 201 is provided with a plug-in portion 204, and the female terminals 202 and the female terminal signal pin module 203 are arranged in the plug-in portion 204.

[0086] When the plug 1 is inserted into the socket 2, the plug-in portion 204 of the socket 2 will enter the plug-in cavity 120 of the plug 1, and the female terminals 202 are docked with the male terminals 105, and the female terminal signal pin module 203 is docked with the common terminal signal pin module 121, so as to achieve the transmission of current and signals.

[0087] Since the connector provided by the embodiment of the present application includes the plug 1 of the above embodiment, it has all the technical effects of the plug 1 of the above embodiment, which will not be elaborated here.

[0088] The above are only the preferred embodiments of the present application, and are not intended to limit the embodiments of the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the embodiments of the present application shall be included in the protection scope of the embodiments of the present application.
