Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to a dummy battery pack. Background Art

[0002] A battery pack generally refers to an integral formed by a plurality of battery cells through series and parallel combinations. It can not only store and release electric energy, but also be responsible for the management and distribution of electric energy to ensure the safe, stable and efficient operation of the battery system. Due to the excessive self-weight of the battery pack, when the battery pack is assembled on an electrical device for use, the electrical device will become too heavy. Generally, the electrical device is a handheld machine. When the user holds the electrical device for operation for a long time, it is easy to feel soreness, swelling and pain in the hand. To solve this problem, at present, the battery pack is generally made into a waist pack or a backpack to transfer the weight of the battery pack to the user's waist or back. The battery pack and the electrical device are generally connected through a dummy pack. The dummy pack usually includes a housing, a contact piece assembly and a conductive assembly electrically connected to the battery pack, etc. By electrically connecting the conductive assembly with the contact piece assembly and the contact piece assembly with the electrical device, the connection between the battery pack and the electrical device is realized.

[0003] The conductive assembly generally includes a protective sleeve installed on the housing and a cable passing through the protective sleeve. In order to prevent damage to the connection between the protective sleeve and the housing during use, in the prior art, the housing and the protective sleeve are generally connected through a connecting seat, that is, one end of the connecting seat is fixedly connected to the protective sleeve and the other end is rotatably connected to the housing, so that the housing can limit the position of the conductive assembly through the connecting seat and can also rotate relative to the conductive assembly by a limited angle. However, the rotation is basically around a fixed axis, and the rotation direction of the housing is limited within a plane and cannot rotate in different plane directions. When the housing is inserted into the electrical device, that is, when the electrical device rotates relative to the protective sleeve, the rotation direction will be restricted, so that when the user holds the electrical device for work, the conductive assembly will impose certain restrictions on the operation direction, thus causing great interference to the user's operation. Therefore, it needs to be improved. Summary of the Utility Model

[0004] The utility model provides a dummy battery pack to overcome the deficiencies in the prior art, which reduces the restriction of the conductive assembly on the user's use direction and reduces the interference of the conductive assembly to the user.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A dummy battery pack includes a housing, a conductive component, and a contact piece component electrically connected to the conductive component. The conductive component is used to electrically connect the battery pack, and the contact piece component is used to electrically connect the electrical device. The conductive component has a spherical joint. The housing has a spherical socket cavity and a limiting hole communicating with each other. The conductive component passes through the limiting hole, and the rotation range of the conductive component around the spherical joint is limited by the limiting hole. The spherical socket cavity is provided with a limiting portion, and the spherical joint is rotatably received in the spherical socket cavity, and the movement of the spherical joint in the axial direction of the conductive component is restricted by the limiting portion.

[0007] In the above technical solution, when connecting the battery pack and the electrical device through this dummy pack, the housing is inserted into the electrical device so that the electrical device is electrically connected to the contact piece component. The spherical joint is rotatably received in the spherical socket cavity, and the sliding of the spherical joint in the axial direction of the conductive component is restricted by the limiting portion, that is, the connection between the housing and the conductive component is realized through the spherical joint. The conductive component passes through the limiting hole, and the rotation range of the conductive component around the spherical joint is limited by the limiting hole, that is, the conductive component can rotate within a certain range in the limiting hole and can at least rotate in one plane. At the same time, due to the spherical arrangement of the spherical joint, the spherical joint can rotate relative to the housing around the axis of the conductive component, that is, it can rotate around multiple axes passing through the center of the sphere, which enables the conductive component to rotate relative to the housing in multiple planes. When the user holds the electrical device for use, the housing is installed on the electrical device, that is, the electrical device can rotate relative to the conductive component in multiple planes, so that the rotation direction of the electrical device is no longer limited to one plane, thereby reducing the restriction of the conductive component on the rotation direction of the electrical device, reducing the restriction of the conductive component on the user's use direction, making it more convenient for the user to operate, and reducing the interference of the conductive component on the user. In addition, the spherical joint can rotate relative to the housing in multiple planes, reducing the risk of damage to the conductive component due to bending during use, thereby improving the service life of the conductive component.

[0008] Preferably, the limiting portion is the cavity wall of the spherical socket cavity, and the cavity wall of the spherical socket cavity cooperates with the outer wall of the spherical joint to restrict the movement of the spherical joint.

[0009] In this structure, the limiting portion directly uses the cavity wall of the spherical socket cavity, without adding other parts in the spherical socket cavity to restrict the movement of the spherical joint, simplifying the composition structure of the dummy pack and making it more convenient for the processing and assembly of the dummy pack.

[0010] Preferably, a damping member is provided between the cavity wall of the spherical socket cavity and the outer wall of the spherical joint.

[0011] In the said structure, when the spherical joint rotates, the damping member can convert the hard contact between the spherical joint and the wall of the spherical socket cavity into a flexible contact, absorb impacts and provide buffering, thereby reducing the impact of the wall of the spherical socket cavity on the spherical joint, preventing excessive impact of the wall of the spherical socket cavity on the spherical joint from causing severe wear of the spherical joint, increasing the service life of the spherical joint, and thus reducing the use cost; at the same time, it also reduces the risk of the severely worn spherical joint falling off from the spherical socket cavity, improving the stability of the false package during use; in addition, the frictional force between the damping member and the spherical joint is relatively large, so that the spherical joint will not rotate randomly after rotating to the corresponding angle, making it more convenient for the user to operate.

[0012] Preferably, the damping member is configured as the limiting portion, and the damping member cooperates with the outer wall of the spherical joint.

[0013] In the said structure, while the damping member plays a role in buffering and increasing the frictional force, it can also be directly configured as the limiting portion without adding other parts in the spherical socket cavity to limit the movement of the spherical joint, simplifying the composition structure of the false package and making it more convenient for the processing and assembly of the false package.

[0014] Preferably, the housing includes a spherical socket seat, the spherical socket cavity is defined within the spherical socket seat, the spherical socket seat has a limiting opening communicating with the spherical socket cavity, the spherical joint is provided with a limiting protrusion, and the limiting protrusion is limited to move within the limiting opening.

[0015] In the said structure, the limiting protrusion is limited to move within the limiting opening, thereby limiting the rotation range of the limiting protrusion. Since the limiting protrusion is installed on the spherical joint, the rotation range of the spherical joint around the axis direction of the conductive component within the spherical socket cavity is limited, preventing the rotation angle of the spherical joint from being too large and causing excessive bending of the conductive component, reducing the risk of damage to the conductive component due to excessive bending, and improving the stability of the false package during use.

[0016] Preferably, the spherical joint is integrally formed with an abutting block, and the abutting block can abut against the wall of the limiting hole to limit the rotation range of the conductive component.

[0017] In the said structure, the abutting block abuts against the wall of the limiting hole to prevent the wall of the limiting hole from causing wear or damage to the conductive component, thereby increasing the service life of the conductive component; generally, the abutting block and the spherical joint are made of hard materials, and the conductive component is generally made of soft materials. The abutting block and the spherical joint are integrally formed, which can simplify the composition structure of the false package and facilitate the processing and assembly of the false package.

[0018] Preferably, the outer shell includes an outer shell body, and the contact piece assemblies are all disposed inside the outer shell body. The outer shell body includes a first side, a second side opposite to the first side, and a connecting wall connecting the first side and the second side. The first side is provided with plugging holes corresponding to the contact piece assemblies, and the limiting holes are formed in the outer shell body and extend from the connecting wall to the second side.

[0019] In this structure, the electrical device can be inserted into the plugging holes to be electrically connected to the contact piece assemblies. The plugging holes are formed on the first side, and the limiting holes extend from the connecting wall to the second side. The first side and the second side are opposite to each other, so as to prevent the electrical device from hindering the rotation of the conductive assembly in the limiting holes. Thereby, it is ensured that the conductive assembly can at least rotate around the spherical joint in one plane, reducing the influence of the electrical device on the rotation of the conductive assembly and improving the stability of the use of the dummy package.

[0020] Preferably, the outer shell includes a first shell body and a second shell body which are separately arranged. The first shell body and the second shell body are assembled to form a wiring cavity for accommodating the contact piece assemblies. The wiring cavity is communicated with the ball socket cavity, and the conductive assembly enters the wiring cavity to be electrically connected to the contact piece assemblies.

[0021] In this structure, the separate arrangement of the first shell body and the second shell body facilitates the installation and replacement of the contact piece assemblies and the conductive assembly. In addition, when it is necessary to replace the conductive assembly or the contact piece assemblies, the first shell body and the second shell body can be reused later, thereby reducing the use cost.

[0022] Preferably, the outer shell includes an outer shell body and a ball socket seat. The ball socket seat includes a first ball socket seat and a second ball socket seat which are separately arranged. The first ball socket seat and the second ball socket seat enclose the ball socket cavity. The first ball socket seat or the second ball socket seat is integrally formed with the outer shell body. The first ball socket seat or the second ball socket seat is provided with an elastic clamping portion, and the spherical joint is pre-tightened by the elastic clamping portion and pre-assembled with the first ball socket seat or the second ball socket seat as a component.

[0023] In this structure, the separate arrangement of the first ball socket seat and the second ball socket seat facilitates the accommodation of the spherical joint into the ball socket cavity. In addition, the first ball socket seat or the second ball socket seat is integrally formed with the outer shell body, simplifying the assembly steps of the dummy package, thereby improving the convenience of assembling the dummy package. Moreover, when the dummy package is assembled or disassembled, the spherical joint can be pre-assembled with the first ball socket seat or the second ball socket seat as a component, reducing the risk of the spherical joint falling off during the assembly or disassembly of the dummy package, and thus being more convenient for the assembly or disassembly of the dummy package.

[0024] Preferably, the spherical joint includes a first hemispherical joint and a second hemispherical joint which are separately arranged, and the first hemispherical joint and the second hemispherical joint are detachably clamped around the conductive component.

[0025] In this structure, the first hemispherical joint and the second hemispherical joint are detachably clamped around the conductive component, that is, the spherical joint and the conductive component are fixedly connected, thereby preventing the conductive component from detaching from the spherical joint, reducing the risk that the internal structure of the conductive component is exposed and damaged due to external factors, and ensuring the stability of the false package during use; in addition, the connection between the spherical joint and the conductive component is detachable, so that when one of the spherical joint and the conductive component needs to be replaced, it is not necessary to replace both of them, which is convenient for the replacement of the spherical joint and the conductive component, and enables one of them to be reused subsequently, thereby reducing the use cost.

[0045] Embodiment 1

[0046] Referring to Figure 1 and Figure 2 A dummy battery pack includes a housing 100, a conductive component 200, and a contact piece component 300 electrically connected to the conductive component 200. The conductive component 200 is used for electrically connecting the battery pack, and the contact piece component 300 is used for electrically connecting the electrical device. The conductive component 200 has a spherical joint 400. The housing 100 has a spherical socket cavity 121 and a limiting hole 111 that communicate with each other. The conductive component 200 passes through the limiting hole 111, and the rotation range of the conductive component 200 around the spherical joint 400 is limited by the limiting hole 111. The spherical socket cavity 121 is provided with a limiting portion 1211. The spherical joint 400 is rotatably received in the spherical socket cavity 121, and the movement of the spherical joint 400 in the axial direction of the conductive component 200 is restricted by the limiting portion 1211.

[0047] According to a dummy battery pack of the present embodiment, when connecting the battery pack and the electrical device through this dummy battery pack, the housing 100 is inserted into the electrical device so that the electrical device is electrically connected to the contact piece assembly 300. The spherical joint 400 is rotatably received in the ball socket cavity 121 and the slippage in the axial direction of the conductive assembly 200 is restricted by the limiting portion 1211, that is, the connection between the housing 100 and the conductive assembly 200 is realized through the spherical joint 400; the rotation range of the conductive assembly 200 passing through the limiting hole 111 and rotating around the spherical joint 400 is limited by the limiting hole 111, that is, the conductive assembly 200 can rotate within a certain range in the limiting hole 111 and can rotate at least in one plane. At the same time, due to the spherical arrangement of the spherical joint 400, the spherical joint 400 can rotate relative to the housing 100 around the axis of the conductive assembly 200, that is, it can rotate around multiple axes passing through the center of the sphere, which enables the conductive assembly 200 to rotate relative to the housing 100 in multiple planes. When the user holds the electrical device for use, the housing 100 is installed on the electrical device, which enables the electrical device to rotate relative to the conductive assembly 200 in multiple planes, so that the rotation direction of the electrical device is no longer limited to one plane, thereby reducing the limitation of the conductive assembly 200 on the rotation direction of the electrical device, thus reducing the limitation of the conductive assembly 200 on the use direction of the user, making it more convenient for the user to operate and reducing the interference of the conductive assembly 200 to the user; in addition, the spherical joint 400 can rotate relative to the housing 100 in multiple planes, reducing the risk of damage to the conductive assembly 200 due to bending during use, thereby increasing the service life of the conductive assembly 200.

[0048] Referring to Figure 1 and Figure 2 , the housing 100 includes a housing body 110 and a ball socket seat 120 for defining the ball socket cavity 121. Taking the height direction of the housing body 110 as the Z-axis direction, the length direction of the housing body 110 as the X-axis direction, and the width direction of the housing body 110 as the Y-axis direction, a coordinate system is established with the X-axis, Y-axis, and Z-axis.

[0049] Referring to Figure 1 , Figure 2 and Figure 3, the contact piece assembly 300 is built into the housing body 110. The housing body 110 includes a first side 112, a second side 113 opposite to the first side 112, and a connecting wall 114 connected between the first side 112 and the second side 113. The first side 112 is provided with a plug-in hole 1121 corresponding to the contact piece assembly 300. The limiting hole 111 is opened on the housing body 110, and the limiting hole 111 extends from the connecting wall 114 to the second side 113. The electrical device can be inserted into the plug-in hole 1121 to be electrically connected to the contact piece assembly 300. The plug-in hole 1121 is opened on the first side 112, and the limiting hole 111 extends from the connecting wall 114 to the second side 113. The first side 112 and the second side 113 face away from each other, so as to prevent the electrical device from hindering the rotation of the conductive component 200 in the limiting hole 111. Thereby, it is ensured that the conductive component 200 can at least rotate around the spherical joint 400 in the XZ plane, reducing the influence of the electrical device on the rotation of the conductive component 200 and improving the stability of the use of the dummy package.

[0050] Preferably, referring to Figure 2 , Figure 3 and Figure 4 , the spherical joint 400 is integrally formed with an abutting block 410, and the abutting block 410 can abut against the hole wall of the limiting hole 111 to limit the rotation range of the conductive component 200. The abutting block 410 is used to abut against the hole wall of the limiting hole 111 to prevent the hole wall of the limiting hole 111 from causing wear or damage to the conductive component 200, thereby improving the service life of the conductive component 200; the abutting block 410 and the spherical joint 400 are generally made of hard materials, and the conductive component 200 is generally made of soft materials. The abutting block 410 and the spherical joint 400 are integrally formed, which can simplify the composition structure of the dummy package and facilitate the processing and assembly of the dummy package.

[0051] Preferably, referring to Figure 2 , Figure 3 and Figure 4 , the distance between the two sides of the hole opening of the limiting hole 111 in the Y-axis direction is greater than the width of the abutting block 410 in the Y-axis direction, so that the conductive component 200 can rotate around the spherical joint 400 in the XZ plane relative to the housing 100 and can also rotate around the spherical joint 400 in the YZ plane, that is, the electrical device can rotate relative to the conductive component 200 in more planes, thereby further reducing the restriction of the conductive component 200 on the rotation direction of the electrical device, further reducing the restriction of the conductive component 200 on the user's use direction, making it more convenient for the user to operate, and further reducing the interference of the conductive component 200 to the user.

[0052] Further, the outer shell 100 includes a first shell 115 and a second shell 116 which are separately arranged. The first shell 115 and the second shell 116 are assembled to form a wiring cavity 117 for receiving the contact piece assembly 300. The wiring cavity 117 communicates with the ball socket cavity 121. The conductive component 200 enters the wiring cavity 117 and is electrically connected to the contact piece assembly 300. Exemplarily, referring to Figure 2 , Figure 3 and Figure 4 , a plurality of fastening screws 1161 pass through the second shell 116. The first shell 115 is provided with fastening grooves corresponding to the fastening screws 1161 one by one. The fastening screws 1161 are threadedly connected in the corresponding fastening grooves, thereby realizing the detachable connection between the first shell 115 and the second shell 116. The separate arrangement of the first shell 115 and the second shell 116 facilitates the installation and replacement of the contact piece assembly 300 and the conductive component 200. In addition, when the conductive component 200 or the contact piece assembly 300 needs to be replaced, the first shell 115 and the second shell 116 can be reused subsequently, thereby reducing the use cost.

[0053] In the above embodiments of the present utility model, the connection manner between the first shell 115 and the second shell 116 is not limited to the fastening screws 1161, and can also be bolts, pins or buckles, etc. For example, the first shell 115 is fixedly connected with a plurality of buckles, and the second shell 116 is provided with buckle grooves corresponding to the buckles one by one. The buckles are snap-fitted with the corresponding buckle grooves to realize the detachable connection between the first shell 115 and the second shell 116.

[0054] Preferably, referring to Figure 2 , Figure 3 and Figure 4 , the ball socket base 120 includes a first ball socket base 122 and a second ball socket base 123 which are separately arranged. The first ball socket base 122 and the second ball socket base 123 enclose a ball socket cavity 121. The first ball socket base 122 is integrally formed with the outer shell body 110. Exemplarily, the first ball socket base 122 is integrally formed with the second shell 116. A plurality of mounting screws 1231 pass through the second ball socket base 123. The first ball socket base 122 is provided with mounting grooves 1221 corresponding to the mounting screws 1231 one by one. The mounting screws 1231 are threadedly connected in the corresponding mounting grooves 1221, thereby realizing the detachable connection between the first ball socket base 122 and the second ball socket base 123. The separate arrangement of the first ball socket base 122 and the second ball socket base 123 facilitates the accommodation of the spherical joint 400 into the ball socket cavity 121. In addition, the first ball socket base 122 or the second ball socket base 123 is integrally formed with the outer shell body 110, which simplifies the assembly steps of the dummy package, thereby improving the convenience of the dummy package assembly.

[0055] In the above embodiments of the present utility model, the first ball socket seat 122 and the first housing 115 may also be integrally formed, or the second ball socket seat 123 and the first housing 115 may be integrally formed, or the second ball socket seat 123 and the second housing 116 may be integrally formed.

[0056] In the above embodiments of the present utility model, the first ball socket seat 122 and the second ball socket seat 123 may also be integrally formed with the first housing 115 and the second housing 116 respectively. In this way, the assembly between the first ball socket seat 122 and the second ball socket seat 123 is realized while the assembly between the first housing 115 and the second housing 116 is carried out, further simplifying the steps of dummy package assembly, thereby improving the convenience of dummy package assembly.

[0057] In the above embodiments of the present utility model, the connection manner between the first ball socket seat 122 and the second ball socket seat 123 is not limited to the mounting screw 1231, and may also be connected by means of bolts, pins or snaps.

[0058] Preferably, the limiting portion 1211 is the cavity wall of the ball socket cavity 121, and the cavity wall of the ball socket cavity 121 cooperates with the outer wall of the spherical joint 400 to limit the movement of the spherical joint 400. Exemplarily, referring to Figure 4 and Figure 5 , the sides of the first ball socket seat 122 and the second ball socket seat 123 close to the spherical joint 400 are arranged in an arc shape and are in contact with the spherical joint 400, that is, the cavity wall of the ball socket cavity 121 abuts against the outer wall of the spherical joint 400, thereby limiting the movement of the spherical joint 400, and thus realizing the connection between the conductive component 200 and the housing 100. Among them, the limiting portion 1211 directly uses the cavity wall of the ball socket cavity 121, and there is no need to add other parts in the ball socket cavity 121 to limit the movement of the spherical joint 400, simplifying the composition structure of the dummy package and making it more convenient for the processing and assembly of the dummy package.

[0059] Preferably, the ball socket seat 120 has a limiting port 124 communicating with the ball socket cavity 121, and the spherical joint 400 is provided with a limiting protrusion 420, and the limiting protrusion 420 is limited to move within the limiting port 124. Exemplarily, referring to Figure 4 , the limiting protrusion 420 is arranged in an L shape; wherein the limiting protrusion 420 is limited to move within the limiting port 124, so that when the limiting protrusion 420 rotates to the limit position, the limiting protrusion 420 abuts against the side wall of the limiting port 124, thereby limiting the rotation range of the limiting protrusion 420. The limiting protrusion 420 is installed on the spherical joint 400, thereby limiting the rotation range of the spherical joint 400 rotating around the axis of the conductive component 200 in the ball socket cavity 121, preventing the spherical joint 400 from rotating too much and the conductive component 200 from being excessively bent, reducing the risk of damage to the conductive component 200 due to excessive bending, and improving the stability of the dummy package during use.

[0060] Preferably, an elastic clamping portion 500 is provided on the second ball socket seat 123, and the spherical joint 400 is pre-tightened by the elastic clamping portion 500 and pre-assembled with the second ball socket seat 123 as a component. Exemplarily, referring to Figure 5 and Figure 6 , the elastic clamping portion 500 is an elastic block 510 fixedly connected to both ends of the second ball socket seat 123. The elastic block 510 is made of an elastic material such as rubber. On the opposite sides of the two elastic blocks 510 facing each other, a receiving groove 600 is formed by enclosing the side of the second ball socket close to the spherical joint 400. The spherical joint 400 is located in the receiving groove 600. The opposite sides of the two elastic blocks 510 are arranged in an arc shape and are in contact with the outer wall of the spherical joint 400. The distance between the two sides of the opening of the receiving groove 600 is smaller than the diameter of the spherical joint 400, thereby restricting the movement of the spherical joint 400 relative to the second ball socket seat 123. That is, when assembling the false package, a thrust is applied to the spherical joint 400 so that the spherical joint 400 will apply a thrust to the two elastic blocks 510, causing the two elastic blocks 510 to undergo elastic deformation and maintain a tendency to reset. The two elastic blocks 510 will move in a direction away from each other, thereby increasing the distance between the two sides of the opening of the receiving groove 600, enabling the spherical joint 400 to enter the receiving groove 600. After that, the elastic blocks 510 will reset, that is, the opposite sides of the two elastic blocks 510 will be in contact with the outer wall of the spherical joint 400, and the distance between the two sides of the opening of the receiving groove 600 will be smaller than the diameter of the spherical joint 400 again, thereby restricting the movement of the spherical joint 400 relative to the second ball socket seat 123, that is, pre-tightening the spherical joint 400 and the second ball socket seat 123 as a component, thereby reducing the risk of the spherical joint 400 falling off during the assembly or disassembly of the false package, and thus making it more convenient for the assembly or disassembly of the false package.

[0061] In the above embodiment of the present invention, the second ball socket seat 123 and the elastic clamping portion 500 can also be integrally formed. For example, both the elastic block 510 and the second ball socket seat 123 are made of an elastic material such as plastic and integrally formed, simplifying the processing steps of the false package and making it more convenient for the processing of the false package.

[0062] In the above embodiment of the present invention, the elastic clamping portion 500 can also be installed on the first ball socket seat 122.

[0063] Preferably, referring to Figure 5 , Figure 6 and Figure 7 , the opposite sides of the two elastic blocks 510 are in contact with the side of the first ball socket seat 122 close to the spherical joint 400, so that during use, the first ball socket seat 122 can restrict the elastic deformation of the elastic block 510, reducing the risk of the spherical joint 400 disengaging from the receiving groove 600 and improving the stability of the false package during use.

[0064] Preferably, the spherical joint 400 includes a first hemispherical joint 430 and a second hemispherical joint 440 that are separately arranged, and the first hemispherical joint 430 and the second hemispherical joint 440 are detachably clamped around the conductive component 200. Exemplarily, referring to Figure 2 、 Figure 4 and Figure 8 , the conductive component 200 includes a cable 210 and a protective sleeve 220 sleeved on the cable 210. Placement grooves 431 are formed on the opposite sides of the first hemispherical joint 430 and the second hemispherical joint 440. A through hole 450 communicating with the ball socket cavity 121 is formed by the two placement grooves 431 enclosing each other. The protective sleeve 220 is inserted into the through hole 450, and a limiting block 221 is fixedly connected to the circumferential outer wall thereof. Limiting grooves 432 communicating with the through hole 450 are formed on the opposite sides of the first hemispherical joint 430 and the second hemispherical joint 440. The groove wall of the limiting groove 432 is arranged in an arc shape. The limiting block 221 is inserted and matched with the limiting groove 432. The limiting block 221 is made of an elastic material such as rubber. A limiting block 4321 is fixedly connected to the groove wall of the limiting groove 432. The limiting block 4321 tightly abuts against the limiting block 221 to limit the rotation of the limiting block 221, thereby realizing the connection between the conductive component 200 and the spherical joint 400; A plurality of connecting screws 441 are inserted through the second hemispherical joint 440, and connecting grooves 433 corresponding to the connecting screws 441 are formed in the first hemispherical joint 430. The connecting screws 441 are threadedly connected in the corresponding connecting grooves 433, thereby realizing the detachable connection between the first hemispherical joint 430 and the second hemispherical joint 440, so that the first hemispherical joint 430 and the second hemispherical joint 440 are detachably clamped around the conductive component 200, that is, the spherical joint 400 and the conductive component 200 are fixedly connected, thereby preventing the protective sleeve 220 in the conductive component 200 from detaching from the spherical joint 400, reducing the risk of the cable 210 being exposed and damaged due to external factors, and ensuring the stability of the false package during use; In addition, the connection between the spherical joint 400 and the conductive component 200 is detachable, so that when one of the spherical joint 400 and the conductive component 200 needs to be replaced, it is not necessary to replace both of them, which is convenient for the replacement of the spherical joint 400 and the conductive component 200, and enables one of them to be reused later, thereby reducing the use cost.

[0065] In the above embodiment of the present invention, the connection method between the first hemispherical joint 430 and the second hemispherical joint 440 is not limited to the connecting screw 441, and may also be a bolt, a pin or a buckle, etc.

[0066] In the above embodiment of the present utility model, the notch of the limiting groove 432 can also be polygonal, and the limiting block 221 is a polygonal block matching the limiting groove 432. Thus, when the limiting block 221 is inserted into the limiting groove 432, the groove walls of the limiting groove 432 will restrict the rotation and movement of the limiting block 221, thereby realizing the connection between the protective sleeve 220 and the spherical joint 400.

[0067] To fix the cable 210 in the wiring cavity 117, a cable fixing groove 118 for clamping the cable 210 is provided in the wiring cavity 117. Exemplarily: Refer to Figure 3 and Figure 4 , two clamping plates 119 are fixedly connected to the wall of the wiring cavity 117. The opposite ends of the two clamping plates 119 enclose to form the cable fixing groove 118. The distance between the two side walls of the cable fixing groove 118 is smaller than the width of the cable 210. That is, when the cable 210 is clamped into the cable fixing groove 118, the circumferential side wall of the cable 210 will undergo elastic deformation, so that the circumferential side wall of the cable 210 is in close contact with the groove wall of the cable fixing groove 118, thereby fixing the cable 210. Thus, the cable 210 is prevented from being pulled out of the wiring cavity 117, ensuring the stability of the false package during use; at the same time, the cable 210 can be neatly installed in the wiring cavity 117, preventing the cable 210 from winding around the contact piece assembly 300, reducing the risk that the cable 210 affects the connection between the contact piece assembly 300 and the electrical equipment, and further ensuring the stability of the false package during use; in addition, the operation of clamping the cable 210 into the cable fixing groove 118 is simple and convenient.

[0068] In the above embodiment of the present utility model, the cable 210 in the wiring cavity 117 can also be fixed by a pressing plate. For example, the pressing plate is provided with a plurality of fixing screws, and fixing grooves corresponding to the fixing screws are provided on the wall of the wiring cavity 117. The fixing screws are threadedly connected in the corresponding fixing grooves, thereby realizing the detachable connection between the pressing plate and the housing body 110. One side of the pressing plate and the wall of the wiring cavity 117 enclose to form the cable fixing groove 118, and the distance between the two side walls of the cable fixing groove 118 is smaller than the width of the cable 210.

[0069] Embodiment 2

[0070] Compared with Embodiment 1, the difference in this embodiment is that a damping member 700 is provided between the wall of the ball socket cavity 121 and the outer wall of the spherical joint 400. Exemplarily, refer to Figure 2 and Figure 5, the damping member 700 is an elastic pad 710 fixedly connected to the wall of the ball socket cavity 121. The elastic pad 710 is made of an elastic material with a large coefficient of friction such as rubber. An assembly groove 1232 is formed on one side of the second ball socket seat 123 close to the spherical joint 400, and the elastic pad 710 is fixedly connected in the assembly groove 1232; when the spherical joint 400 rotates, the elastic pad 710 can convert the hard contact between the spherical joint 400 and the wall of the ball socket cavity 121 into a flexible contact and can absorb shocks and buffer, thereby reducing the impact of the wall of the ball socket cavity 121 on the spherical joint 400, preventing the wall of the ball socket cavity 121 from hitting the spherical joint 400 too hard and causing serious wear of the spherical joint 400, improving the service life of the spherical joint 400, and thus reducing the use cost; at the same time, it also reduces the risk of the spherical joint 400 falling off from the ball socket cavity 121 due to serious wear, improving the stability of the false package; in addition, the friction force between the elastic pad 710 and the spherical joint 400 is relatively large, so that the spherical joint 400 will not rotate randomly after rotating to the corresponding angle, which is more convenient for the user to operate.

[0071] In the above embodiment of the present invention, the damping member 700 may also be an elastic pad 710 fixedly connected to the outer wall of the spherical joint 400.

[0072] Preferably, the damping member 700 is configured as a limiting portion 1211, and the damping member 700 cooperates with the outer wall of the spherical joint 400. Exemplarily, the elastic pad 710 is fixedly connected to the wall of the ball socket cavity 121 and abuts against the outer wall of the spherical joint 400 on the side close to the spherical joint 400, thereby restricting the movement of the spherical joint 400; wherein the elastic pad 710 can also be directly configured as the limiting portion 1211 while buffering and increasing the friction force, without adding other parts in the ball socket cavity 121 to restrict the movement of the spherical joint 400, simplifying the composition structure of the false package and making it more convenient for the processing and assembly of the false package.
