Description

[Technical Field]

[0001] This application relates to the technical field of electrical devices, and more particularly to connectors. [Background technology]

[0002] Connectors play an important role in the fields of current and signal transmission as a conductive structure between two devices or systems. For example, a plug-in connection is used to connect energy storage battery packs, which generally consists of two parts installed in the two devices or systems. Usually, one terminal is fixedly installed on the battery pack and the other terminal is a floating terminal, and the electrical connection of the battery pack is achieved by plugging these two terminals together.

[0003] The fixed and floating end openings of the current connectors are perfectly aligned, which means there is a risk of them being installed backwards. If the connector on one battery pack is not installed correctly, that battery pack will not be able to be attached to other battery packs.

[0004] In the prior art, a connector includes two plug cores that are connected by a plug-in mechanism, each of which includes a mounting shell and a plug module. The mounting shell is typically fixed to a corresponding device with fasteners such as bolts. A mounting hole for mounting the plug module is typically provided in the center of the mounting shell, and structures such as snaps are provided on both sides of the mounting hole for securing the plug module. Each mounting hole typically accommodates multiple different types of plug modules, such as a signal module and a power module. Because a product employs a modular assembly design, there is a risk of incorrect module installation during use. For example, if a power module and a signal module are included, the power module and the signal module must be installed in a specific order on the frame. Otherwise, the battery pack to which the connector is attached cannot be installed. Summary of the Invention [Problem to be solved by the invention]

[0023] The present invention provides a connector in which the female socket is integrally formed with the first body and the male socket is integrally formed with the second body, so that when the connector is installed, it is only necessary to connect the first body and the second body to the first device and the second device, respectively, and electrical continuity can be established between the first device and the second device by plugging and mating the first plug core and the second plug core. Compared to the prior art, which requires the installation of a separate plug mold, the installation process of the connector provided by the present invention is simplified, which effectively reduces installation difficulty and the possibility of installation errors, improves connector installation efficiency, and ensures that the battery pack connected to the connector is properly installed and electrically connected.

[0024] As shown in Figures 1 and 2, the connector comprises a first plug core 1 and a second plug core 2. The first plug core 1 is used for movably connecting to a first device, and comprises a first body 11 and a female socket 12 formed integrally with the first body 11. The second plug core 2 is used for fixedly connecting to a second device, and comprises a second body 21 and a male socket 22 formed integrally with the second body 21. The female socket 12 and the male socket 22 are connected by plug fitting, establishing electrical continuity between the first device and the second device.

[0025] Specifically, the first body 11 is plate-shaped, one side of which fits against the surface of the housing of the first device, and is connected to the first device by attaching a bolt to a slot structure such as an oval hole, so that the first plug core 1 can float within a certain range relative to the first device and correspond to the second plug core 2.

[0026] The cross section of first body 11 can be square, circular, or any other shape connectable to the first device, and is not limited thereto in the present application. Female socket 12 penetrates the center of first body 11, with one end located within the first device and electrically connected to the circuit system within the first device, and the other end extending through first body 11 to the outside of the first device and being inserted into male socket 22. Female socket 12 is formed integrally with first body 11, i.e., first body 11 including female socket 12 is formed during the manufacturing process by a method such as injection molding.

[0027] The second body 21 is fixed directly to the second device by fasteners such as bolts, and its shape can be set to match the shape of the first body 11. The method of attaching the male socket 22 is the same as that of the female socket 12, so a repeated explanation will not be given here.

[0028] By forming the female socket 12 integrally with the first body 11 and the male socket 22 integrally with the second body 21, there is no need to install a separate plug-in module; instead, it is sufficient to simply connect the first body 11 and the second body 21 to the first device and the second device, respectively, i.e., electrical continuity between the first device and the second device is achieved by plugging the female socket 12 into the male socket 22. Therefore, when installing the connector, there is no need to consider the problem of incorrect installation of the plug-in module, which effectively simplifies the connection and installation process of the battery pack, while at the same time reducing the difficulty of installation and the possibility of connector installation errors, so the connector can effectively achieve smooth installation and connection of the battery pack.

[0029] As shown in FIG. 2, in some embodiments of the present application, 2 Plug Core 2 The plug 122 has a pin 122 and a plug cover 123. Male socket 22 It is located inside. Plug Cover 123 teeth Male socket 22 Established in 2 Plug Core 2The positive or negative electrode of the

[0030] specifically, Male socket 22 is hollow, and pin 122 is Male socket 22 Located within Male socket 22 A locking structure such as a snap can be provided inside the pin 122 to fix the pin 122. One end of the pin 122 is connected to a lead wire and is electrically connected to a corresponding device, and the other end is female socket 12 Inside Insert into The plug cover 123 is provided at one end located at the first device in the female socket 12, and the plug cover 123 may be painted with different colors to indicate whether it is a positive or negative electrode. In this embodiment, the positive plug cover 123 is painted with orange paint, and the negative plug cover 123 is painted with black paint.

[0031] Pin 122 directly Male socket 22 and plug cover 123. Male socket 22 By holding down 2 Plug Core 2 The installation is completed, and the plug cover 123 of different colors indicates the positive or negative pole. 2 Plug Core 2 This clarifies the installation direction when installing the product, further reducing the difficulty of installation.

[0032] As shown in FIG. 2, in some embodiments of the present application, pin 122 Male socket 22 and the plug cover 123 is snapped on. Male socket 22 The plug cover 123 is partially Male socket 22 Insert inside And , contacting the end face of the pin 122 and Male socket 22 Fix it to.

[0033] Specifically, pin 122 Male socket 22 The plug cover 123 is provided with a through hole for accommodating the electric wire, and a snap is provided on the outer wall of the through hole. Male socket 22 and the plug cover 123 is fitted to the outer wall of the Male socket 22 Here, the plug cover 123 is provided with a stopper portion for fixing the pin 122, and the bottom end of the stopper portion comes into contact with the top surface of the pin 122 to fix the pin 122. The bottom end of the stopper portion is a movable end, Male socket 22 The axial direction of the shaft is movable outward.

[0034] Male socket 22 In the production process, the plug cover 123 and Male socket 22 Pin 122 with snap Male socket 22 The pin 122 can be fixed in place within the plug cover 123, and the installation is simple and does not require much time, contributing to improved production efficiency. Furthermore, when the pin 122 needs to be inspected or replaced, the retractor can be used to move the bottom end of the stopper portion outward in its diameter direction, allowing the pin 122 to be easily extracted from the plug cover 123, facilitating inspection or replacement of the pin 122.

[0035] 1 and 2, in some embodiments of the present application, a plurality of female sockets 12 are provided. Specifically, a plurality of female sockets 12 can be provided in the first body 11. For example, two sets of parallel female sockets 12 are provided, and the first set of female sockets 12 are provided with orange or red plug covers 123 as positive poles, and the second set of female sockets 12 are provided with black plug covers 123 as negative poles. In this way, the first body 11 can be electrically connected to various power terminals of the first device, which effectively improves the adaptability of the female sockets 12.

[0036] 1 and 2, in some embodiments of the present application, the first plug core 1 includes a signal terminal 124. The signal terminal 124 is integrally formed with the first body 11. Specifically, the signal terminal 124 can be installed between the two pairs of female sockets 12, and a corresponding pin 122 can be disposed inside the signal terminal 124 to communicate with a signal transmission terminal in the first device. By integrating the signal terminal 124 and the female socket 12, the first plug core 1 integrates two modules, power and signal, which broadens the application range of the first plug core 1 and enables the first plug core 1 to meet the connection needs between various devices.

[0037] As shown in FIG. 3, in some embodiments of the present application, the cross section of the second body 21 is rectangular, and mounting screw holes 211 are formed on both sides of the second body 21 for attaching bolts to connect to the second device, and the two mounting screw holes 211 are asymmetrically distributed about the central axis of the second body 21.

[0038] Specifically, mounting screw holes 211 are provided in the center of both the left and right sides of second body 21, and the line connecting the two mounting screw holes 211 is not parallel to any side of second body 21, so the two mounting screw holes 211 are offset from each other. By arranging the two mounting screw holes 211 offset from each other, when installing second body 21, the two mounting screw holes 211 can be aligned with the corresponding screw holes of the second device only when installing second body 21 in the correct installation direction; otherwise, the mounting screw holes 211 cannot be aligned with the corresponding screw holes of the second device, making installation impossible. This prevents installation of second plug core 2 in the wrong direction, allowing the worker to quickly determine the installation direction of second plug core 2 and further reducing the difficulty of installation.

[0039] 3, in some embodiments of the present application, second body 21 has fastening screw holes 212 on both sides of mounting screw hole 211 for attaching bolts for connecting to the second device, thereby enabling second plug core 2 to be more stably attached to the second device. During installation, the user can fasten second plug core 2 to the second device through any of mounting screw holes 211 or fastening screw holes 212. It should be understood that the number of fastening screw holes 212 can be designed according to the size of second body 21 and is not limited to the installation method in the above example.

[0040] 4 and 5, in some embodiments of the present application, a mounting hole 111 is provided in the first body 11, and a washer 112 is provided in the mounting hole 111. A first clearance 113 is formed between the washer 112 and the mounting hole 111, and a bolt is inserted through the washer 112, with one end of the bolt abutting against the washer 112 and the other end penetrating the washer 112 to be connected to the first device.

[0041] Specifically, the mounting hole 111 is an oval hole, and the longitudinal cross section of the washer 112 is T-shaped. Its upper end is a disk, and its lower end is a cylinder integrally formed with the disk. The outer diameter of the cylinder is smaller than the diameter of the mounting hole 111, and its height is greater than the depth of the mounting hole 111. This allows a certain gap to be maintained between the underside of the disk and the side of the first body 11. The gap between the disk and the plug core and the gap between the cylinder and the mounting hole 111 jointly form a first clearance 113. The bolt passes through the disk and cylinder of the washer 112 and is then connected to the first device. Specifically, the gap between the disk and the first body 11 and the gap between the cylinder and the mounting hole 111 can be designed based on actual installation conditions and are not limited in this application. In this embodiment, the gap between the disk and the first body 11 is 0.2 mm, and the gap between the cylinder and the wall of the mounting hole 111 is 3.2 mm.

[0042] By inserting a bolt through the mounting hole 111 and the washer 112, the first body 11 can be connected to the outer shell of the first device, and when the female socket 12 and the male socket 22 are plugged in and connected, the second connector 2 does not move relative to the second device, so that when the female socket 12 and the male socket 22 are plugged in and connected, the first plug core 1 can float to a certain extent, so that the female socket 12 and the male socket 22 are aligned and the possibility of the female socket 12 and the male socket 22 being misaligned is reduced.

[0043] 4 and 5, in some embodiments of the present application, the first body 11 is provided with a mounting portion 114 for mounting the floating bolt 3, and the mounting portion 114 can be configured as a mounting hole or mounting groove with a notch, or as a mounting hole or mounting groove without a notch. A second gap 115 is formed between the floating bolt 3 and the mounting portion 114, and one end of the floating bolt 3 firmly abuts against the first body 11 and the other end passes through the mounting portion 114 to be connected to the first device.

[0044] Specifically, U-shaped openings serving as mounting portions 114 are provided on both the left and right sides of the first body 11, and the mounting portions 114 are located between the two mounting holes 111. The sides of the mounting portions 114 are raised to form pads, and the bolt rod of the floating bolt 3 includes a first portion 31 and a second portion 32. The first portion 31 is located inside the pads and the mounting portions 114. The length of the first portion 31 is greater than the thickness of the pads and the mounting portions 114, creating a gap between the nut and the pad. Meanwhile, the outer diameter of the first portion 31 is smaller than the size of the mounting portions 114, creating a gap between the first portion 31 and the mounting portions 114, resulting in a second clearance 115. The second portion 32 is threaded and connected to the housing of the first device, and its outer diameter is smaller than that of the first portion 31. The specific size of the second clearance 115 can be designed according to actual installation requirements and is not limited herein.

[0045] The floating bolt 3 is provided within the mounting portion 114, and the floating range between the floating bolt 3 and the first body 11 is limited by a pad, allowing the first body 11 to float appropriately within the second clearance 115 and ensuring a smooth insertion connection between the female socket 12 and the male socket 22. The floating bolt 3 can be provided only within the mounting hole 111, only within the mounting portion 114, or both within the mounting hole 111 and the mounting portion 114. The specific arrangement of the floating bolt 3 can be adjusted according to actual installation needs, and is not specifically limited in this application.

[0046] 3 and 4, in some embodiments of the present application, the first plug core 1 further includes a guide shell portion 13. The guide shell portion 13 is installed in the first body 11, and the female socket 12 is located within the guide shell portion 13. The second plug core 2 includes an assembly shell portion 23. The assembly shell portion 23 is provided on the second body 21 and is connected to the guide shell portion 13 by bayonet fitting, and the male socket 22 is located within the assembly shell portion 23.

[0047] Specifically, the guide shell 13 is formed by protruding from one side of the first body 11 remote from the first device and extending to the other side of the first body 11 remote from the first device, and its cross section may be a polygon such as a rectangle or an arc such as a circle. One end of the female socket 12 penetrates the first body 11 and is inserted into the guide shell 13, and the other end is located inside the first device and is electrically connected to the circuit system in the first device.

[0048] The assembly shell 23 is formed by extending and protruding from one side of the second body 21 that is farther from the second device. The shape of the assembly shell 23 is designed to match the shape of the guide shell 13, and can be guided and fitted by the guide shell 13. The mounting method of the male socket 22 is the same as that of the female socket 12, so a repeated description will not be given here.

[0049] When the connector is plugged in to establish electrical continuity between the first device and the second device, the first plug core is first matched with the second plug core, then the guide shell 13 is plugged into the assembly shell 23, and the female socket 12 is plugged into the male socket 22 through the guiding action of the guide shell 13 and the assembly shell 23. As a result, when plugging in the female socket 12 and the male socket 22, the guiding relationship between the guide shell 13 and the assembly shell 23 can be utilized to quickly complete the plug-in connection, and there is no need to install a separate guide structure for the first plug core 1 and the second plug core 2. The guide shell 13 and the assembly shell 23 are formed by extending the protrusions of the first body 11 and the second body 21 themselves, respectively, which effectively reduces the overall volume of the connector and saves on material usage in the manufacturing process, thereby reducing the manufacturing cost of the connector and improving material utilization efficiency.

[0050] As shown in FIG. 2, in some embodiments of the present application, the cross-sectional area of ​​the assembly shell part 23 is larger than that of the guide shell part 13, and a guide gap 231 for the guide shell part 13 to be inserted is formed between the inside of the assembly shell part 23 and the male socket 22, and the inner wall of the assembly shell part 23 slidably adheres to the outer wall of the guide shell part 13.

[0051] Specifically, the cross sections of the assembly shell 23 and the guide shell 13 are both rectangular, and the length and width of the inner side of the assembly shell 23 are greater than the length and width of the outer side of the guide shell 13. The male socket 22 is disposed at the center of the assembly shell 23, and the end face of the male socket 22 may be flush with the end face of the assembly shell 23, and a certain distance is maintained between the male socket 22 and the inner wall of the assembly shell 23, thereby forming the aforementioned guide gap 231. The end face of the female socket 12 may also be flush with the end face of the guide shell 13, allowing the guide shell 13 to be fully inserted into the assembly shell 23.

[0052] By forming the guide gap 231, when the male socket 22 is inserted into the female socket 12, the guide shell part 13 is inserted into the guide gap 231 in the assembly shell part 23, and the outer wall of the guide shell part 13 slidably adheres to the outer wall of the assembly shell part 23, thereby exerting a guiding effect. As the guide shell part 13 is gradually inserted into the assembly shell part 23, the insertion of the male socket 22 into the female socket 12 is completed normally.

[0053] Referring to FIG. 4, in some embodiments of the present application, an outer wall of the guide shell portion 13 on the side where it is inserted into the assembly shell portion 23 is provided with a guide slope 131 that slidably fits with the assembly shell portion 23.

[0054] Specifically, the open end of the guide shell part 13 is chamfered to form a guide slope 131, which is set facing the assembly shell part 23. The inclination angle of the guide slope 131 can be set to, for example, 45° or 30° depending on the requirements for the plug-in fitting connection.

[0055] By providing the guide slope 131, the cross-sectional area of ​​the end of the guide shell part 13 that is inserted into the assembly shell part 23 can be reduced, making it easier to insert the guide shell part 13 into the assembly shell part 23. At the same time, the guide slope 131 also serves as a guide. When the guide shell part 13 is inserted into the assembly shell part 23, the guide slope 131 can slidably come into contact with the inner wall of the assembly shell part 23, so the guide shell part 13 can slide smoothly into the assembly shell part 23.

[0056] Referring to FIG. 4, in some embodiments of the present application, a plurality of grooves are provided on the outer wall of the guide shell 13, and a guide rib 132 is formed between two adjacent grooves.

[0057] Specifically, the grooves extend in the vertical direction, and the grooves are formed in the guide shell portion 13. Circumferential directionThe guide ribs 132 are arranged at equal intervals along the guide inclined surface 131, thereby forming a plurality of guide ribs 132. One end of the guide rib 132 close to the guide inclined surface 131 may be connected to the guide inclined surface 131 and provided with an inclined surface having a corresponding inclination angle. The guide ribs 132 may be fixed to the outer wall of the guide shell 13 by adhesive or welding. In this case, a ring groove for attaching the guide rib 132 may be provided in the outer wall of the guide shell 13.

[0058] The provision of the groove effectively reduces the amount of material used for the guide shell part 13, and the guide rib 132 effectively fills the remaining gap when the guide shell part 13 is inserted into the guide gap 231, so that the guide shell part 13 and the assembly shell part 23 fit together stably and are less likely to rattle. At the same time, the provision of the guide rib 132 improves the strength of the guide shell part 13 and reduces the possibility of the guide shell part 13 being damaged during the insertion process of the guide shell part 13 and the assembly shell part 23.

[0059] Referring to FIG. 3, in some embodiments of the present application, an assembly inclined surface 232 that slidably fits with the guide shell portion 13 is provided on the inner wall of the assembly shell portion 23 on the side where the guide shell portion 13 is inserted.

[0060] Specifically, the inner wall of the assembly shell part 23 is chamfered to form an assembly slope 232, the inclination angle of which can be designed to match the guide slope 131 of the guide shell part 13, and the assembly slope 232 can be aligned to correspond to the guide slope 131. By providing the assembly slope 232, the opening area of ​​the assembly shell part 23 is enlarged, making it easier to smoothly insert the guide shell part 13 into the assembly shell part 23. The fit between the assembly slope 232 and the guide slope 131 also serves to limit and guide the insertion of the guide shell part 13. As the guide slope 131 comes into contact with the assembly slope 232, the guide shell part 13 and the assembly shell part 23 can be pressed together to align them, thereby preventing misalignment between the guide shell part 13 and the assembly shell part 23.

[0061] In some embodiments of the present application, a seal groove 133 for mounting a seal ring is provided on the outer wall of the guide shell portion 13, and the seal ring abuts against the inner wall of the assembly shell portion 23 to seal the gap between the assembly shell portion 23 and the guide shell portion 13.

[0062] Specifically, the seal groove 133 is fitted around the outer wall of the guide shell 13 and is located below the guide rib 132. The seal ring is bonded to the seal groove 133 with an adhesive. The seal ring may be made of rubber, and one end thereof protrudes from the seal groove 133 and abuts against the inner wall of the assembly shell 23.

[0063] By providing the seal ring, when the guide shell portion 13 is inserted into the assembly shell portion 23, the seal ring can effectively seal the gap between the guide shell portion 13 and the assembly shell portion 23, thereby improving the sealing performance between the guide shell portion 13 and the assembly shell portion 23.

[0064] Needless to say, the above-described embodiments of the present application are merely examples for clarifying the present application, and are not intended to limit the embodiments of the present application. It will be apparent to those skilled in the art that various modifications, rearrangements, and substitutions can be made without departing from the scope of the present application.
