DETAILED DESCRIPTION
[0037] Exemplary embodiments of the present disclosure will now be described in detail with reference to the drawings.
[0038] Embodiments of the first aspect
[0039] As illustrated in Figs. 1 to 5, a storage battery bolt terminal according to an embodiment of the present disclosure includes a terminal 100 including a storage battery post connecting unit 101, compressible units 102 being provided on two sides of an opening end of CPST Doc: 463322.1 the storage battery bolt connecting unit 101, and a cable connecting unit 104 being provided in another opening end of the storage battery post connecting unit 101. The storage battery bolt terminal further includes a gland 200, which includes a pressing unit 201 and two rotating units 202 provided on the pressing unit 201.
[0040] The compressible unit 102 is rotatably connected to the rotating unit 202, and the rotating unit 202 is provided with a locking unit 203. The storage battery post connecting unit 101 is connected to a storage battery post, with a conical shape matched with that of the storage battery post, and a size matched with and greater than that of the storage battery post.
[0041] Further, in order to protect the safety of workers and prevent the workers from directly touching the gland, the gland 200 is externally provided with a protective cover 300 adapted to the pressing unit 201.
[0042] In some implementations, the protective cover 300 is fixedly connected to the gland 200 by clamping. As illustrated in Fig. 4, the protective cover includes a main unit 301 and a clamping unit 302, and the main unit of the protective cover 300 is of rectangular shape.
As illustrated in Figs. 2-1, 2-2 and 4-1, the gland 200 is of circular or triangular shape, and the protective cover 300 is of circular shape. It can be understood that the gland is of any circular or polygonal shape, and the protective cover 300 may be of any circular or polygonal shape as long as it is matched with the pressing unit 201. The protective cover 300 should cover the gland 200 to ensure that the gland is not touched by human hands when the storage battery bolt terminal is in operation. The function of the clamping unit 302 is to clamp the gland 200 without loosening or falling off. There may be one clamping unit 302 at the top and the bottom, respectively, or the number of the clamping units 302 may also be three, four, five, etc.
[0043] In other implementations, the protective cover 300 and the gland 200 may be connected in other ways, which is not limited herein.
[0044] According to the embodiment, the disconnection and connection of the storage battery bolt terminal can be realized by simple manual operations, and assembly or disassembly of the storage battery bolt terminal and the storage battery post can be achieved by pressing or raising the protective cover, so that the bolt tightening tool is omitted, the maintenance convenience is greatly improved, the structure is simple and practical, the manufacturing process is simple, and the mounting cost is reduced, thus having outstanding practical values.
[0045] As illustrated in Figs. 1-1 and 1-2, the storage battery post connecting unit is a sleeve hole structure (e.g., a cylindrical hole), and the sleeve hole of the storage battery post connecting unit is disposed to sleeve the storage battery post, wherein the storage battery post is a conical cylinder.
CPST Doc: 463322.1
[0046] As illustrated in Fig. 2, the locking unit 203 is provided on one of the rotating units 202. The locking unit 203 is a strip-shaped structure protruding from the rotating unit 202, and a side of the locking unit 203 close to a rotating end of the rotating unit is an inclined surface.
[0047] In some implementations, in order to improve the efficiency of the locking unit 203 compressing the compressible unit 102, a position where the locking unit 203 contacts the compressible unit 102 is a transition corner, by which the opening between the compressible units 102 is gradually narrowed by compressing. The transition corner mentioned herein refers to a rounded arc corner.
[0048] When the protective cover 300 is rotatably pressed, the gland 200 is rotated toward the terminal 100, and when the gland 200 is rotated to the above of the terminal 100, the locking unit 203 compresses the compressible unit 102 to shrink the opening between the compressible units 102, thus locking the terminal 100 with the storage battery post, and realizing the connection and contact between the storage battery bolt terminal and the storage battery post.
[0049] Specifically, as illustrated in Figs. 7-1 to 7-3, the specific process of connecting the storage battery bolt terminal to the storage battery post includes:
firstly, the gland 200 is in an open state, and the locking unit 203 does not compress the compressible unit 102, as illustrated in Fig. 7-1; in this state, the protective cover 300 is rotatably pressed to drive the gland 200 to be rotated towards the terminal 100, the locking unit 203 compresses the compressible unit 102, and the opening between the compressible units 102 shrink; as illustrated in Fig. 7-2, the protective cover 300 is continued to be rotatably pressed to drive the gland 200 to be rotated towards the terminal 100, and the gland 200 drives the locking unit 203 to compress the compressible unit 102 until the protective cover 300 cannot move, thus locking the terminal 100 and the storage battery post.
[0050] During disassembly of the storage battery bolt terminal, since the protective cover 300 is clamped with the gland 200, the locking unit 203 can be released from the compressible unit once the protective cover 300 is raised by hand, thus realizing the disassembly between the storage battery bolt terminal and the storage battery post, which is very convenient and quick.
The storage battery post connecting unit 101 is connected to the storage battery post and matched with the shape thereof
[0051] In some implementations, a stop unit 103 is provided outside the compressible unit 102, and the stop unit 103 and the locking unit 203 are disposed on opposite sides. During mounting of the storage battery post, the protective cover 300 is pressed to drive the gland 200 to be rotated, so that the rotating unit 202 abuts against the stop unit 103, thus forming a limiting fit between the stop unit 103 and the rotating unit 202. When the protective cover and the gland CPST Doc: 463322.1 are rotated to a certain degree, the rotation of the gland 200 stops. At the same time, the storage battery post connecting unit 101 is connected to the storage battery post.
[0052] The embodiment can prevent the excessive rotation of the gland, and further avoid the phenomenon that the gland contacts the storage battery post to conduct electricity.
[0053] As illustrated in Fig. 4, the protective cover 300 is made of a flame retardant hard material. Different types of materials, such as PBT-GF30, PA6, PA66, PC/ABS, etc., are selected for the protective cover 300 depending on strengths, temperature-resistant grades, and material characteristics, and any material should meet the requirements of flame retardance and strength.
[0054] The terminal 100 and the gland 200 are both integrally formed, ensuring that the storage battery bolt terminal is firmer. Different types of materials, such as red copper, brass, lead brass, etc., may be selected for the terminal 100 depending on the machining process, electrical conductivity and material characteristics. The surface of the terminal 100 is plated with tin, silver, nickel, etc. depending on the environmental requirements, thus meeting the requirements of electrical conductivity and corrosion resistance. The gland 200 may be made of red copper, brass, lead brass, carbon steel, low-carbon steel, stainless steel, etc. depending on the machining process. In order to meet the requirement of corrosion resistance, the surface of the copper-containing material may be plated with tin, silver and nickel depending on environmental requirements, and the surface of the carbon steel may be plated with zinc, zinc-nickel alloy, etc.
[0055] As illustrated in Figs. 2, 2-1 and 2-2, the structure of the pressing unit 201 may be of any circular or polygonal shape, and exemplarily, the structure of the pressing unit 201 is of rectangular shape. The pressing unit 201 is clamped and matched with the protective cover 300, and the pressing unit 201 may be pressed and raised in the process of pressing and raising the protective cover 300.
[0056] As illustrated in Figs. 3 and 3-1 to 3-6, the cable connecting unit 104 includes at least one wiring hole, and crimping or welding may be adopted according to the connection mode of the cable. According to the outgoing line direction, the direction of the wiring hole of the cable connecting unit 104 may be 0 to 180 . The cable connecting unit 104 is connected to the cable, and has a circular profile that matches the shape of the wire. The alternative profile is a circular or any polygonal shape. According to the connection mode of the cable, crimping or welding may be adopted. Depending on the number of the cables connected, the cable connecting unit 104 may have one, two or three wiring holes, etc. Depending on the outgoing line direction, the opening direction of the wiring holes may be 0 to 180 .
Figs. 3-1 to 3-3 are CPST Doc: 463322.1 diagrams of terminal turning, and the opening direction of the wiring hole may be 0 or 180 .
As illustrated in Figs. 3-4 to 3-6, the opening direction of the wiring hole is 90 , and may be adjusted to any direction of 0 to 1800 depending on the outgoing line direction.
[0057] Specifically, the adjustment range of the direction of the wiring hole is 00 to 180 on a vertical plane where the cable connecting unit is located (as illustrated in Fig. 8-1) and/or 0 to 180 on a horizontal plane where the cable connecting unit is located (as illustrated in Fig.
8-2).
[0058] Specifically, the vertical plane where the cable connecting unit is located refers to a plane formed by adjustable paths of the cable connecting unit in a vertical direction (abbreviated as a YZ plane), and as illustrated in Fig. 8-1, which illustrates, from left to right, the outgoing line directions of 0 , 45 , 90 , 135 and 180 on the YZ plane.
[0059] The horizontal plane where the cable unit is located refers to a plane formed by adjustable paths of the cable in a horizontal direction (abbreviated as an XY
plane), and as illustrated in Fig. 8-2, which illustrates, from left to right, the outgoing line directions of 0 , 45 ,90 , 135 and 180 on the XY plane.
[0060] In some implementations, as illustrated in Fig. 5, the compressible units 102 are hinged to the rotating units 202 by a rotating shaft 400, and the rotating shaft 400 connects the terminal 100 and the gland 200 to play roles of connection and rotation. The rotating shaft 400 includes a central shaft cap unit 401, a central shaft unit 402 and a plug unit 403, wherein the central shaft cap unit 401 is of circular shape to prevent the rotating shaft from falling off, and the alternative profile is of circular or polygonal shape such as ellipse shape, square shape, etc.
The central shaft unit 402 is of cylindrical shape to play roles of connection and rotation. The plug unit 403 is of concave circular shape and is detachably provided on the central shaft unit 402 to prevent the gland 200 and the terminal 100 from falling off.
[0061] During implementation, firstly, the plug unit 403 is separated from the central shaft unit 402, and the central shaft unit 402 is enabled to pass through mounting holes of the rotating unit 202 and the compressible unit 102. The plug unit 403 is interference-fitted into the mounting hole of the central shaft unit 402, or screwed into a threaded hole of the central shaft unit 402.
[0062] The embodiments have a characteristic of simple structure, which facilitates the mounting of the compressible unit and the rotating unit.

[0064] As illustrated in Figs. 1 to 6, the storage battery bolt terminal according to an embodiment includes a terminal 100. The terminal 100 includes a storage battery post CPST Doc: 463322.1 connecting unit 101, compressible units 102 provided on two sides of an opening end of the storage battery bolt connecting unit 101, and a cable connecting unit 104 in another opening end of the storage battery post connecting unit 101. The storage battery bolt terminal further includes a gland 200, which includes a pressing unit 201, and two rotating units 202 provided on a side of the gland 200 and on the pressing unit 201.
[0065] The compressible unit 102 is rotatably connected to the rotating unit 202, and the rotating unit 202 is provided with a locking unit 203. The storage battery post connecting unit 101 is connected to a storage battery post, with a conical shape matched with that of the storage battery post, and a size matched with and greater than that of the storage battery post. The gland 200 is externally provided with a protective cover 300 adapted to the pressing unit 201, and the protective cover 300 is fixedly connected to the gland 200 by clamping. The protective cover includes a main unit 301 and a clamping unit 302, and the main unit of the protective cover 300 is of rectangular shape. As illustrated in Figs. 2-1, 2-2 and 4-1, the gland 200 is of circular or triangular shape, and the protective cover 300 is of circular shape. It can be understood that the gland is of any round or polygonal shape, and the protective cap 300 may be of any circular or polygonal shape as long as it is matched with the pressing unit 201. The function of the clamping unit 302 is to clamp the gland 200 without loosening or falling off.
There may be one clamping unit 302 at the top and the bottom, respectively, or the number of the clamping units 302 may also be three, four, five, etc.
[0066] After the storage battery bolt terminal is mounted to sleeve the storage battery post, when the protective cover 300 is rotatably pressed, the gland 200 is rotated to the above of the terminal 100, the locking unit 203 compresses the compressible unit 102 to lock the terminal 100 with the storage battery post. During disassembly of the storage battery bolt terminal, since the protective cover 300 is clamped with the gland 200, the locking unit 203 can be released from the compressible unit once the protective cover 300 is raised by hand, thus realizing the disassembly between the storage battery bolt terminal and the storage battery post, which is very convenient and quick. The storage battery post connecting unit 101 is connected to the storage battery post and matched with the shape thereof A stop unit 103 is provided outside the compressible unit 102, and the stop unit 103 and the locking unit 203 are disposed on opposite sides. During mounting of the storage battery post, the protective cover 300 is pressed to drive the gland 200 to be rotated, so that the rotating unit 202 abuts against the stop unit 103, thus forming a limiting fit between the stop unit 103 and the rotating unit 202.
When the protective cover and the gland are rotated to a certain degree, the rotation of the gland 200 stops. At the same time, the storage battery post connecting unit 101 is connected to the storage battery post.
CPST Doc: 463322.1
[0067] As illustrated in Fig. 4, the protective cover 300 is made of a flame retardant hard material. Different types of materials, such as PBT-GF30, PA6, PA66, PC/ABS, etc., are selected for the protective cover 300 depending on strengths, temperature-resistant grades, and material characteristics, and any material should meet the requirements of flame retardance and strength.
[0068] The terminal 100 and the gland 200 are both integrally formed, ensuring that the storage battery bolt terminal is firmer. Different types of materials, such as red copper, brass, lead brass, etc., may be selected for the terminal 100 depending on the machining process, electrical conductivity and material characteristics. The surface of the terminal 100 is plated with tin, silver, nickel, etc. depending on the environmental requirements, thus meeting the requirements of electrical conductivity and corrosion resistance. The gland 200 may be made of red copper, brass, lead brass, carbon steel, low-carbon steel, stainless steel, etc. depending on the machining process. In order to meet the requirement of corrosion resistance, the surface of the copper-containing material may be plated with tin, silver and nickel depending on environmental requirements, and the surface of the carbon steel may be plated with zinc, zinc-nickel alloy, etc.
[0069] As illustrated in Figs. 2, 2-1 and 2-2, the pressing unit 201 may be of any circular or polygonal shape, and exemplarily, the pressing unit 201 is of rectangular shape. The pressing unit 201 is clamped and matched with the protective cover 300, and the pressing unit 201 may be pressed and raised in the process of pressing and raising the protective cover 300.
[0070] As illustrated in Figs. 6-1 and 6-2, the cable connecting unit 104 and the cable are connected by screwing. As illustrated in Fig. 5, the compressible unit 102 is hinged to the rotating unit 202 by a rotating shaft 400, which connects the terminal 100 and the gland 200 to play roles of connection and rotation. The rotating shaft 400 includes a central shaft cap unit 401, a central shaft unit 402 and a plug unit 403, wherein the central shaft cap unit 401 is of circular shape to prevent the rotating shaft from falling off, and the alternative profile is of circular or polygonal shape such as ellipse shape, square shape, etc. The central shaft unit 402 is of cylindrical shape to play roles of connection and rotation. The plug unit 403 is of concave circular shape to prevent the gland 200 and the terminal 100 from falling off.
