References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0034] In order to solve the problem of poor waterproof performance of the assembly between the device and the connector in the related art and poor connection stability between the device and the connector, a connection socket is provided in the embodiment of the present application. Figures 1 to 5 As shown, the connection socket includes:

[0035] An assembly panel 1 includes a first surface 11 and a second surface 12 disposed opposite to each other along an axial direction. A socket body 13 is formed in the central region of the first surface 11. The socket body 13 includes a slot 14 that opens along the axial direction. An elastic seal 2 is provided in at least the region outside the central region of the first surface 11.

[0036] The electrical connector 3 is fixedly inserted into the assembly panel 1 along the axial direction; the electrical connector 3 has a first end 31 and a second end 32 opposite to each other along the axial direction, and the first end 31 protrudes from the assembly panel 1 from the first surface 11 and extends into the slot 14;

[0037] The fixing part 4 is arranged on the assembly panel 1 and is used to fix the connecting socket to the device housing 7; wherein, the device housing 7 is provided with an assembly through hole 71 whose opening size and shape match the socket body 13, the socket body 13 is passed through the assembly through hole 71, and the assembly panel 1 elastically abuts against the device housing 7 around the assembly through hole 71 through the elastic sealing part 2 to form a seal.

[0038] The connection socket in the embodiment of the present application is used to provide a connection interface for equipment such as engineering machinery, agricultural machinery, and heavy-duty equipment. Therefore, the connection socket forms a fixed connection and an electrical connection with the equipment on the one hand, and on the other hand, it also needs to provide an interface for communication with the outside world; wherein, in order to form a fixed connection and an electrical connection between the connection socket and the equipment, please refer to Figure 5 , it is necessary to open a corresponding assembly through-hole 71 on the device housing 7. On the one hand, the assembly through-hole 71 can locate the position of the connection socket and limit the range of movement of the connection socket. On the other hand, it allows the connection socket to be connected to the inside and outside of the device. Internally, the connection socket can form an electrical connection with the device, and externally, it provides an interface for the outside world, allowing the connection plug to form a connection with the connection socket. It is worth mentioning that the inside and outside of the connection socket in the embodiment of the present application are only relative to the location where the connection socket is currently set, and are not limited to being set at the outermost layer of the device. In fact, for multi-layered devices, the connection socket in the embodiment of the present application can be set on any layer of the housing to achieve electrical connection.

[0039] Please refer to Figures 1 to 2 To achieve a fixed connection between the connecting socket and the device housing 7, the connecting socket has an assembly panel 1 having a first surface 11 and a second surface 12 disposed opposite each other. After assembly, the first surface 11 faces the outside of the device housing 7, and the second surface 12 faces the inside of the device housing 7. Because the assembly panel 1 is designed in the embodiment of the present application, the available assembly space can be increased based on the area of ​​the assembly panel 1 when the connecting socket is connected to the device housing 7. For example, multiple fixings 4 can be provided on the assembly panel 1 to ensure surface contact between the assembly panel 1 and the device housing 7.

[0040] In order to facilitate plugging into an external interface, a socket body 13 is formed in the central area of ​​the first surface 11 of the assembly panel 1. The socket body 13 is used to form a plug-in connection with the external interface. Therefore, a slot 14 is formed in the socket body 13, which is open along the axial direction. The slot 14 can be used to accommodate a plug, thereby forming a plug-in connection; the shape and size of the socket body 13 match the shape and size of the required corresponding plug. Among them, the central area refers to the center point of the first surface 11 of the assembly panel 1 and the area near it. In addition to the socket body 13, the first surface 11 of the assembly panel 1 also has other spaces. The other spaces are arranged around the socket body 13. In this way, when the connecting socket is fixed to the device housing 7, the portion of the first surface 11 of the assembly panel 1 surrounding the socket body 13 can be fixed to the device housing 7, thereby improving the stability of the assembly between the assembly panel 1 and the device housing 7.

[0041] Please refer to Figure 3 In order to form an electrical connection, the connection socket also has an electrical connector 3, which is fixed to the assembly panel 1 and inserted into the assembly panel 1. The specific form of the electrical connector 3 can include a structure including a plug-in pin, a pin, etc., and is usually made of a conductive metal material. The two ends of the electrical connector 3 along the axial direction are respectively a first end 31 and a second end 32, wherein the first end 31 is located close to the first surface 11 and the second end 32 is located close to the second surface 12. The first end 31 protrudes from the assembly panel 1 from the first surface 11, so that the electrical connector 3 is equivalent to protruding from the first surface 11 to form an electrical connection portion.

[0042] The first end 31 of the electrical connector 3 extends into the slot 14, and together with the slot 14, forms a socket for an external plug to be inserted. The plug can communicate with the electrical connector 3 to form an electrical connection, or it can cooperate with the electrical connector 3 and the slot 14 to form a fixed connection.

[0043] In order to secure the connecting socket to the device housing 7, the assembly panel 1 is further provided with a fixing member 4. This fixing member 4 serves to securely connect the assembly panel 1 to the device housing 7, thereby enabling the socket body 13 secured to the assembly panel 1 and the electrical connector 3 inserted into the assembly panel 1 to securely connect to the device housing 7 based on the secured assembly panel 1. The device housing 7 is provided with an assembly through-hole 71, the size and shape of which match the socket body 13. During assembly, the socket body 13 is inserted into the assembly through-hole 71, and the first surface 11 of the assembly panel 1 is disposed around the assembly through-hole 71. In order to fill the joint between the first surface 11 and the device housing 7 and improve the waterproof performance of the device, the first surface 11 of the assembly panel 1 is provided with an elastic seal 2 at least in the area other than the central area; when the assembly panel 1 and the device housing 7 are assembled, the first surface 11 is in contact with the device housing 7 through the elastic seal 2, and the elastic seal 2 will undergo elastic deformation due to the close contact between the assembly panel 1 and the device housing 7, and the elastic deformation will fill the gap between the assembly panel 1 and the device housing 7, thereby improving the waterproof performance of the device; moreover, the elastic seal 2 also increases the friction between the assembly panel 1 and the device housing 7, thereby improving the connection stability between the two, thereby improving the reliability of the device.

[0044] Multiple fixings 4 can be set around the assembly panel 1, and each fixing 4 is preferably set in the edge area of ​​the assembly panel 1 to prevent the assembly panel 1 from warping. Based on the shape of the assembly panel 1, the fixings 4 can be set to include four, six, eight, etc. The more fixings 4 there are, the more complicated the connection process is, but the better the fixing effect is.

[0045] In some optional embodiments, in order to achieve a sealed connection, the elastic seal 2 may specifically include an integrally formed panel seal 21 and elastic ribs 22, wherein the panel seal 21 is fixedly disposed in an area other than the central area of ​​the first surface 11; the elastic ribs 22 are protruding from the surface of the panel seal 21 away from the first surface 11, and the elastic ribs 22 are disposed around the edge area of ​​the first surface 11, and the elastic ribs 22 are enclosed to form a closed figure. The panel seal 21 and the elastic ribs 22 are integrally formed, wherein the panel seal 21 is used to form a surface contact with the first surface 11, thereby improving the stability between the elastic seal 2 and the assembly panel 1; the elastic ribs 22 are protruding from the panel seal 21, and the elastic ribs 22 are disposed around the edge area of ​​the first surface 11 to form a closed figure. When the assembly panel 1 is connected to the device housing 7, the areas inside and outside the areas surrounded by the elastic ribs 22 are isolated from each other, thereby avoiding the interaction of water vapor and improving the waterproof performance of the device. It is worth mentioning that the elastic ribs 22 can be provided in one or more circles, wherein the more circles of the elastic ribs 22 there are, the better the sealing performance is, which can prevent the waterproof performance from failing due to local deformation.

[0046] In some optional embodiments, to further enhance waterproof performance and prevent water vapor from penetrating through the fixing member 4, elastic ribs 22 enclose the ends of the fixing member 4. The closed pattern formed by the elastic ribs 22 can also directly enclose the end regions of the fixing member 4, thereby ensuring that the fixing member 4 also has good waterproof performance.

[0047] In some optional embodiments, to further enhance the waterproof performance of the fixing member 4, at least a portion of the elastic rib 22 is disposed around the end of the fixing member 4. In other words, in addition to being disposed entirely around the edge region of the first surface 11, the elastic rib 22 may also be disposed around the end of the fixing member 4. This creates a sealing structure in which the elastic rib 22 forms a large circle around the edge region of the first surface 11 and a small circle around the end of the fixing member 4, further enhancing the sealing and waterproof performance of the fixing member 4.

[0048] In some optional embodiments, in addition to achieving sealing between the first surface 11 of the assembly panel 1 and the device housing 7 based on the elastic ribs 22, the sealing performance of the socket body 13 can be further improved when it is inserted into the assembly through hole 71; therefore, the panel seal 21 can also be integrally covered on the outer surface of the socket body 13, so that when the socket body 13 is inserted into the assembly through hole 71, the panel seal 21 can play a role in sealing the gap between the socket body 13 and the assembly through hole 71.

[0049] The elastic sealing member 2 in the embodiment of the present application can be made of a flexible and elastic material including silicone.

[0050] In some alternative embodiments, please refer to Figure 2 To facilitate electrical connection between the socket and the interior of the device, the second end 32 of the electrical connector 3 can specifically extend along the axial direction and protrude from the second surface 12 for electrical connection to the PCB. The second end 32 of the electrical connector 3 protruding from the second surface 12 allows the electrical connector 3 to be connected to the PCB in a plug-in manner. The PCB can be provided with corresponding conductive sockets, and a fixed and electrical connection can be achieved through socket welding or other methods. Furthermore, the electrical connection between the electrical connector 3 and the PCB can also be established via a flat cable. When using a flat cable connection, the second end 32 of the electrical connector 3 does not need to protrude from the second surface 12.

[0051] In some alternative embodiments, please refer to Figure 2To prevent misalignment and other problems when connecting the electrical connector 3 to the PCB, the second surface 12 may also be provided with a foolproof positioning post 5, which extends along the axis away from the first surface 11. The foolproof positioning post 5 cooperates with the foolproof hole provided on the PCB. Only when the foolproof positioning post 5 and the foolproof hole match each other can the electrical connector 3 be correctly connected to the PCB, thereby preventing reverse connection or misalignment.

[0052] In some alternative embodiments, please refer to Figure 3 Depending on the specific type of electrical connector 3, electrical connector 3 may include a plurality of pins, each of which forms a pin group. Each pin is provided with a connection point 33, which at least partially protrudes from the pin's surface. The pin is fixed to assembly panel 1 through injection molding, and the connection point 33 is embedded within assembly panel 1. The connection point 33 provided on the pin protrudes from the pin's surface, resulting in the pin having a protruding, enlarged structure at the connection point 33. During injection molding of the pin and assembly panel 1, the enlarged connection point 33 is embedded within assembly panel 1, while the two ends of the pin extend outward from the first surface 11 and the second surface 12 of the assembly panel 1, respectively. The connection point 33 secures the pin to the assembly panel 1, preventing the pin from falling off the assembly panel 1.

[0053] In some alternative embodiments, please refer to Figure 4 In order to achieve a fixed connection between the connecting socket and the device housing 7, the fixing part 4 may specifically include a threaded hole or a self-tapping threaded hole, which is used to cooperate with the threaded part to fix the connecting socket to the device housing 7. The difference between the threaded hole and the self-tapping threaded hole is that the threaded hole is pre-set with an internal thread, while the self-tapping threaded hole has no internal thread and needs to be tapped out with a self-tapping threaded part, such as a screw, and a fixed connection is formed by the thread engagement between the self-tapping threaded part and the self-tapping threaded hole. In order to facilitate the self-tapping threaded part to tap out the thread, the self-tapping threaded hole is generally provided with an inner hole. The aperture of the inner hole is smaller than the outer diameter of the thread, but it can play a guiding role for the self-tapping threaded part, making the fitting connection between the self-tapping threaded part and the self-tapping threaded hole tighter and more accurate.

[0054] Also, please refer to Figure 5 In order to form a connection through the fixing member 4, a corresponding connecting through hole 72 generally needs to be provided on the device housing 7. The aperture of the connecting through hole 72 needs to match the self-tapping screw member so that the threaded portion of the self-tapping screw member can pass through while preventing the nut from passing through. In the embodiment of the present application, the connecting through hole 72 can be formed independently in the device housing 7, or it can be connected to the assembly through hole 71.

[0055] In some alternative embodiments, please refer to Figure 1 The same device may often have two or more connection sockets. To prevent incorrect connections when multiple connection sockets are provided, a predetermined number of indicator keys 6 may be provided within slot 14. These indicator keys 6 are protruding from the inner wall of slot 14 and are configured to mate with corresponding connection plugs. By providing indicator keys 6, the corresponding plugs can be determined based on parameters such as the position and number of indicator keys 6, preventing incorrect connections.

[0056] A connecting socket is provided in an embodiment of the present application. Since the assembly panel 1 is provided with an elastic seal 2, when assembled with the device housing 7, the assembly panel 1 forms a sealed connection with the device housing 7 through the elastic seal 2, thereby effectively improving the waterproof performance of the device, and the elastic seal 2 can also improve the anti-slip property of the connection between the connecting socket and the device housing 7, thereby improving the stability of the connection between the connecting socket and the device housing 7, and further improving the reliability of the device.

[0057] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
