DETAILED DESCRIPTION

[0031] Exemplary embodiments will be described in detail with reference to the drawings. In the following description, the same drawing reference numerals are used to denote elements having the same or similar functions and structures, unless otherwise specified. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present application.

[0032] The terms "first", "second", "third", "fourth" and the like used in the description and the claims of the present application and the above-described drawings, if any, are used to distinguish similar objects, and are not necessarily used to describe a particular sequential or chronological order. It should be understood that the data thus used can be interchanged, where appropriate, so that the embodiments of the present application described herein can be carried out in a different order than that depicted or described herein.

[0033] In the embodiments of the present application, the words "exemplarily" or "for example" are used to represent examples, illustrations or descriptions. Any embodiment or design scheme described as "exemplarily" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words "exemplarily" or "for example" are used to present the relevant concept in a specific manner.

[0034] The creepage distance refers to the shortest path measured along the insulating surface between two conductive parts or between a conductive part and a protective interface of an electrical device. The creepage distance is an important indicator for measuring the insulation performance of an electrical device, and is used to ensure that the device will not have electrical breakdown or creepage phenomenon under normal operation and fault conditions. In the related art, two adjacent sockets in the socket are arranged at intervals, but the creepage distance is still limited, and when the electrical equipment is in a high-voltage and high-current working environment, the creepage phenomenon is easily caused.

[0035] The socket and the electrical equipment provided by the present application aim to solve the above technical problems in the prior art and improve the creepage distance between two adjacent sockets.

[0036] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0037] Please refer to Figures 1 to 5 The socket provided by the embodiments of the present application includes a mounting seat 100, a sleeve assembly 200 and a cover 300.

[0038] The mounting seat 100 is provided with at least two mounting grooves 110 arranged at intervals, and a separation piece 120 is arranged between adjacent mounting grooves 110, the top of the separation piece 120 protrudes from the mounting groove 110; the sleeve assembly 200 is arranged in the mounting groove 110, the sleeve assembly 200 includes a sleeve 210 and a pin 220, and the sleeve 210 is connected with the pin 220; the cover 300 is detachably arranged on the mounting seat 100, the cover 300 is provided with a socket 310 and a slot 320, the socket 310 corresponds to the sleeve 210, and the separation piece 120 is inserted into the slot 320.

[0039] The mounting base 100 is a main body of the socket and provides a mounting base for the socket assembly 200 and the cover 300. The mounting slots 110 are used for mounting the socket assembly 200 and are arranged at intervals on the mounting base 100. The isolation pieces 120 are arranged between adjacent mounting slots 110 and protrude from the top ends of the mounting slots 110. In one aspect, the isolation pieces 120 serve as a physical barrier between two adjacent socket assemblies 200, effectively increasing the shortest distance between them, i.e., increasing the creepage distance of the adjacent socket assemblies 200, which helps to reduce the occurrence of creepage and thus improve the electrical safety of the socket. In another aspect, the isolation pieces 120 can be buckled to the insertion slots 320 on the cover 300, which helps to position and mount the cover 300 and improves the connection stability between the cover 300 and the mounting base 100. In addition, the protruding part of the isolation piece 120 can serve as a barrier between the mounting base 100 and the cover 300 to prevent electrical short circuit between adjacent socket assemblies 200 and between the socket 210 and the cover 300, which helps to protect the socket and the electrical equipment. It can be understood that the isolation piece 120 is made of a material with high insulation performance, such as ceramic, plastic, etc. The material with high insulation performance can effectively prevent the current from passing through, and can maintain a stable insulation state even in the presence of a voltage difference.

[0040] The socket assembly 200 includes a socket 210 and a pin 220. The pin 220 is used to connect with the circuit and transmit electrical energy to the socket 210. The socket 210 is used to contact with the plug and transmit electrical energy. The pin 220 is connected with the circuit, thereby transmitting electrical energy from the socket to the plug.

[0041] The cover 300 is buckled on the mounting base 100 to isolate and protect the socket assembly 200 in the mounting slot 110. The cover 300 can be arranged on the mounting base 100 by buckling, screwing or other detachable connection methods. The cover 300 is provided with an insertion hole 310 and an insertion slot 320. The insertion hole 310 corresponds to the socket 210, so that the plug can be smoothly inserted into the socket 210 and contact with it. The insertion slot 320 is inserted with the isolation piece 120, so that the cover 300 is positioned and mounted, improving the stability of the socket.

[0042] Therefore, the socket provided by the embodiment of the present application can effectively increase the creepage distance of the adjacent socket assemblies 200 by arranging the isolation pieces 120 between the adjacent mounting slots 110, reduce the occurrence of creepage, and facilitate the mounting of the cover 300 to the mounting base 100.

[0043] Please refer to Figure 1 and Figure 2In some optional embodiments, the mounting groove 110 includes a first mounting groove for mounting the bushing 210 and a second mounting groove for mounting the pin 220, the second mounting groove being offset from the first mounting groove in a first direction, wherein the first direction is the arrangement direction of the mounting groove 110.

[0044] Specifically, the mounting groove 110 includes a first mounting groove and a second mounting groove, the second mounting groove being offset from the first mounting groove in the arrangement direction of the mounting groove 110, so that the first mounting groove and the second mounting groove are staggered on the mounting base 100. In this way, the second mounting groove for mounting the pin 220 can leave out some space in the offset direction, so that the electrical equipment can better utilize the space away from the offset side and arrange other devices at the position.

[0045] In the related art, some electrical equipment installs the socket at the central position of the equipment cabinet 400, which, however, makes the positions on both sides of the equipment cabinet 400 too narrow and the space on both sides insufficient to be utilized. The staggered arrangement of the present embodiment can leave out space for the electrical equipment, and compared with the parallel arrangement, can optimize the layout of the internal components of the equipment cabinet 400 of the electrical equipment and improve the space utilization efficiency of the electrical equipment.

[0046] Exemplarily, the offset angle of the second mounting groove relative to the first mounting groove includes but is not limited to 30°, 45°, 60° and 75°, or a value between any two ranges thereof.

[0047] Please refer to Figure 3 and Figure 4 In some optional embodiments, the bushing 210 includes a first spring and a second spring arranged at intervals, the first spring having a first clamping portion 211 and the second spring having a second clamping portion 212, the first clamping portion 211 and the second clamping portion 212 being oppositely arranged to clamp the plug pin, and at least one of the first clamping portion 211 and the second clamping portion 212 extending in a direction perpendicular to the groove bottom of the mounting groove 110.

[0048] The first spring and the second spring are oppositely arranged at intervals and form an opening at the top of the bushing 210, the opening being for inserting the plug pin. The first clamping portion 211 and the second clamping portion 212 form the part for clamping the plug pin, so that the plug and the bushing 210 are electrically connected, and the plug pin is prevented from loosening or falling off in the socket through the clamping of the first clamping portion 211 and the second clamping portion 212.

[0049] Since at least one of the first clamping portion 211 and the second clamping portion 212 extends in a direction perpendicular to the bottom of the mounting groove 110, that is, in a direction perpendicular to the bottom of the mounting groove 110, at least one of the first clamping portion 211 and the second clamping portion 212 has a certain length, thereby increasing the contact area of the clamping portion with the plug pin, facilitating to improve the stability of clamping, reducing the resistance caused by poor contact, and improving the efficiency of current transmission.

[0050] Meanwhile, the clamping portion with a certain length can provide more support, so that the clamping force of the bushing 210 can be greater under the same pressure, which helps to ensure the stability of the plug pin in the bushing 210 and prevent loosening caused by vibration or external force. In addition, the clamping portion with a certain length increases the contact area and clamping force of the bushing 210 with the plug pin, thereby avoiding the increase of point contact resistance, facilitating to prolong the service life of the bushing 210 and the plug pin, and reducing wear and damage caused by frequent plugging and unplugging.

[0051] Exemplarily, the first clamping portion 211 and the second clamping portion 212 both extend in a direction perpendicular to the bottom of the mounting groove 110, and both have a certain length.

[0052] Therefore, the embodiment of the present application sets the first clamping portion 211 on the first elastic sheet and the second clamping portion 212 on the second elastic sheet, and at least one of the first clamping portion 211 and the second clamping portion 212 extends in a direction perpendicular to the bottom of the mounting groove 110, which is beneficial to improve the stability and reliability of electrical connection and the clamping stability of the bushing 210.

[0053] Please refer to Figure 3 and Figure 4 In some optional embodiments, the bushing assembly 200 further comprises an elastic clamping piece 230, which is sleeved on the bushing 210 to clamp the bushing 210.

[0054] The elastic clamping piece 230 is sleeved on the bushing 210 to form a double-layer elastic structure. The elastic clamping piece 230 can additionally clamp the bushing 210 by using its own elasticity, so that the first elastic sheet and the second elastic sheet tend to approach each other, thereby enhancing the clamping effect of the elastic clamping piece 230 on the bushing 210, ensuring good contact between the bushing 210 and the plug pin, reducing the resistance and heat generated by poor contact, facilitating to enhance the connection stability between the bushing 210 and the plug pin, improve the efficiency of current transmission and reduce energy consumption, and at the same time, reduce the safety hazards caused by overheating.

[0055] During the insertion or extraction of the plug pin, the elastic clamping piece 230 can play a certain buffering and damping effect, reducing the impact and vibration generated by the insertion and extraction operation. This helps to protect the plug sleeve 210 and the plug pin from damage and prolong the service life of the product.

[0056] Exemplarily, the elastic clamping piece 230 can be made of a material with high elasticity, wear resistance and corrosion resistance, such as rubber, silicone, to ensure that the elastic clamping piece 230 maintains stable elasticity and clamping force during long-term use.

[0057] Therefore, the socket of the embodiment of the present application enhances the clamping stability of the plug sleeve 210 through the elastic clamping piece 230, and improves the electrical performance of the socket.

[0058] Exemplarily, please refer to Figure 5 In some optional embodiments, the bottom of the elastic clamping piece 230 is provided with a welding point 233 for welding connection with the mounting groove to realize fixed installation.

[0059] In some optional embodiments, the elastic clamping piece 230 includes a first clamping piece 231 and a second clamping piece 232, the first clamping piece 231 is attached to the first elastic piece, and the second clamping piece 232 is attached to the second elastic piece.

[0060] The first clamping piece 231 is attached to the first elastic piece, and the second clamping piece 232 is attached to the second elastic piece, that is, the shape of the first clamping piece 231 matches the shape of the first elastic piece, and the shape of the second clamping piece 232 matches the shape of the second elastic piece, thereby facilitating to improve the connection stability of the elastic clamping piece 230 and the plug sleeve 210, and to uniformly distribute the elastic force of the elastic clamping piece 230, which is conducive to ensuring that the plug sleeve 210 can be uniformly stressed when the plug pin is inserted, and improving the stability and reliability of clamping.

[0061] Therefore, the elastic clamping piece 230 of the embodiment of the present application can further improve the clamping effect and electrical safety of the plug sleeve assembly 200 through the first clamping piece 231 and the second clamping piece 232.

[0062] Exemplarily, the elastic clamping piece 230 has the same shape as the plug sleeve 210, and can be sleeved on the outside of the plug sleeve 210.

[0063] In some optional embodiments, a connecting plate is provided between the plug sleeve 210 and the plug pin 220, the connecting plate is provided with a positioning portion 240, and the positioning portion 240 is positioned and matched with the mounting groove 110.

[0064] The positioning part 240 on the connecting plate is matched with the positioning of the mounting groove 110, which provides an accurate installation position for the socket 210. This helps to reduce errors during installation and ensures that the socket 210 can be accurately inserted into the socket 320. At the same time, through the guidance of the positioning part 240, the installer can more easily align the socket 210 with the mounting groove 110, thereby simplifying the installation process and improving the installation efficiency of the socket.

[0065] In some alternative embodiments, the connecting plate is provided with a positioning hole, and the mounting groove 110 is provided with a positioning protrusion corresponding to the positioning hole; or the connecting plate is provided with a positioning protrusion, and the mounting groove 110 is provided with a positioning hole corresponding to the positioning protrusion.

[0066] The connecting plate and the mounting groove 110 are matched by the positioning of the positioning protrusion and the positioning protrusion, which can ensure the accuracy of the socket 210 during installation and reduce installation errors.

[0067] When the socket 210 is installed in the mounting groove 110 through the connecting plate, the positioning protrusion will enter the positioning hole, which helps to ensure that the socket 210 is installed to the predetermined position in the mounting groove 110. After the positioning protrusion enters the positioning hole, they are limited to each other, which increases the stability between the socket 210 and the mounting groove 110.

[0068] In some alternative embodiments, the mounting seat 100 and the face cover 300 are connected by a first threaded connecting piece 301.

[0069] The threaded connecting piece, such as a screw or a bolt, is matched with the threaded hole on the mounting seat 100 and the face cover 300 through its threaded structure, achieving firm connection between them. The threaded connecting piece can provide a large pre-tightening force, so that the mounting seat 100 and the face cover 300 are tightly combined and not easy to loosen. The threaded connecting piece is a standardized component, widely used in various devices and structures, easy to obtain and replace.

[0070] For example, threaded holes are provided on the mounting seat 100 and the face cover 300 respectively, and then a screw is used to directly pass through the face cover 300 and be screwed into the threaded hole of the mounting seat 100.

[0071] In some alternative embodiments, the bottom side of the pin 220 is provided with a riveting piece 221, and the top side of the pin 220 is provided with a wiring terminal 222, which is connected with the riveting piece 221 through a second threaded connecting piece.

[0072] The wiring terminal 222 is used to connect with external wires or cables. The wiring terminal 222 can accommodate and clamp the wires to make the external wires or cables connected with the socket 210 stable.

[0073] Exemplarily, threaded holes are arranged on the rivet 221 and the terminal 222 respectively, so that the threaded connectors can be screwed into and fixed on the two. In order to prevent the threaded connectors from loosening during use, some anti-loosening measures can be taken, such as applying anti-loosening agent, using locking washer or spring washer, etc.
