The base is provided with electrical components electrically connected to the display. Therefore, electrical connection terminals are respectively provided in the base and the column, and when the base and the column are assembled, electrical connection of the two electrical connection terminals is achieved at the same time.

[0004] However, due to the limited cross-sectional space of the column, the electrical connection terminal occupies a large fixed space, and the fixed connection space on the column is insufficient, resulting in poor connection stability between the column and the base. Utility Model Content

[0030] The embodiment of the present application makes the fifth connection hole on the first bracket opposite to the second connection hole of the first recess through the cooperation of the first positioning portion and the second positioning portion, which is beneficial to improving the assembly efficiency of the first bracket fixed to the first recess.

[0031] In some embodiments of the present application, the aperture of the first connection hole is larger than the aperture of the second connection hole.

[0032] In this way, by setting the larger aperture of the first connection hole, the stability of the fixed connection between the adapter and the base assembly can be ensured.

[0033] In some embodiments of the present application, the aperture of the third connection hole is larger than the aperture of the second connection hole.

[0036] The cooperation of the protruding portion and the first notch of the connecting rod and the adapter in the embodiments of the present application enables the third connection hole on the adapter to be opposite to the connection hole on the connecting rod, improving the convenience of assembling the connecting rod and the adapter. Moreover, the cooperation of the first notch and the protruding portion plays a guiding role in inserting the adapter into the first channel.

[0037] In a second aspect, embodiments of the present application provide a display device, which includes:

[0038] A display component configured to display image information;

[0039] A connecting rod, one end of the connecting rod is connected to the display component, and the other end of the connecting rod is fixedly connected with an adapter;

[0043] A second electrical connector is fixed in the base, and when the base is fixedly connected to the adapter, the second electrical connector is electrically connected to the first electrical connector.

[0044] The display device of the embodiment of the present application includes a display component, a connection component and a base component, and the connection component connects the base component and the display component. The connection component includes a connection rod, an adapter and a first electrical connection component, and the base component includes a base and a second electrical connection component. A plurality of first connection holes and a first recessed portion are arranged on the end surface of the adapter away from the connection rod, a second connection hole and a second recessed portion are arranged on the bottom wall of the first recessed portion, and a plurality of third connection holes are arranged on the second recessed portion. The plurality of third connection holes, the second connection holes and the plurality of third connection holes all extend along the length direction of the connection rod, but are arranged in layers in the length direction in the adapter, which can not only realize sufficient arrangement space for multiple connection holes, but also ensure the aperture of the connection holes, thereby ensuring the stability and reliability of the connection between the connection component and the base component.

[0045] Among them, the multiple first connection holes are used to realize the fixed connection between the adapter and the connecting rod. The second connection holes are used to realize the fixed connection between the first electrical connector and the adapter. The multiple third connection holes are used to realize the fixed connection between the adapter and the base. The multiple first connection holes and the multiple third connection holes are conducive to improving the reliability of the fixed connection between the adapter and the connecting rod, and the adapter and the base.

[0046] When the adapter and the base are fixedly connected by the first fastener, the connecting rod abuts against the base, thereby hiding the adapter inside the connecting rod and the base, with no fastener exposed; at the same time, the first electrical connector and the second electrical connector are electrically connected without the need for additional operations, thereby improving the convenience of users in assembling the connection component and the base component.

[0047] Moreover, since the first connecting hole and the second connecting hole are both arranged inside the adapter, there are no exposed fasteners on the side of the adapter. Even when the connecting component is not assembled to the base component, there are no exposed fasteners on the side of the connecting component, thereby improving the aesthetics of the connecting component.

[0048] In some embodiments of the present application, the plurality of first connection holes and the plurality of third connection holes are arranged alternately and spaced along the circumference of the adapter.

[0049] Such an arrangement enables the fixed connections between the adapter and the connecting rods and base assemblies at both ends to be arranged alternately, which can not only ensure the reliability of the connection between the adapter and the connecting rod and the base assembly, but also help to improve the uniformity of the force on the adapter and reduce the impact on its service life due to uneven force on the adapter.

[0071] To make the purpose, implementation and advantages of this application clearer, the following will clearly and completely describe the exemplary implementation of this application with reference to the accompanying drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0072] It should be noted that the brief description of the terms in this application is only for the convenience of understanding the subsequent described implementation, rather than intending to limit the implementation of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0073] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion. For example, a product or device including a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0074] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0075] The terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0076] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0077] The movable display device includes a column, a base, and a display. The top end of the column is connected to the display, and the bottom end of the column is connected to the base. Electrical components are arranged in the base and electrically connected to the display. For example, a battery is configured in the base to supply power to the display. Therefore, electrical connection terminals are respectively arranged in the base and the column.

[0078] Generally, in order to make the packaging box compact, the base and the column are usually separated and assembled by the user himself. When assembling the base and the column, the two electrical connection terminals need to be electrically connected. To improve the convenience of assembly, the electrical connection terminals in the base and the electrical connection terminals in the column usually adopt a plug-in manner.

[0079] In some products, the bottom end of the column is usually connected to a column adapter. The column adapter is inserted into the base and fixedly connected to the base. When the column is docked with the base to achieve the fixed connection between the column and the base, the connection structure between the column and the base is hidden inside to ensure the aesthetics of the appearance.

[0080] The column adapter needs to be fixedly connected to the column and the base, and electrical connection terminals also need to be fixed on the column adapter. However, due to the limited cross-sectional space of the column, the fixed connection positions cannot be arranged.

[0081] One way is to arrange all the fixing screws along the axial direction of the column. By reducing the size of the screws, the fixing connection positions can be arranged in a limited space. However, thinner screws affect the connection stability.

[0082] Another way is to set the fixing screws of the column adapter and the column on the side, that is, the screws fix the column adapter and the column along the radial direction of the column. However, not only do the exposed screws affect the aesthetics, but also the side walls of the column adapter and the column are relatively thin, resulting in poor connection stability, causing the column adapter and the column to shake, and even generating abnormal noises, thus affecting the connection stability between the column and the base.

[0083] The R & D personnel of this application continued to research. On the premise of ensuring that the screws are not exposed on the circumferential side, then all the fixing screws need to be arranged along the axial direction. How to arrange a large number of screws in a limited cross-sectional space? Among them, reducing the number of screws and using thinner screws are not conducive to connection stability.

[0084] The cross-sectional space of the column adapter is limited, but its axial space is sufficient. Therefore, the R & D personnel of this application arranged a large number of screws in layers along the axial direction, which can not only ensure the number of screw connections and the stability of the fixed connection, but also avoid the exposure of the screws.

[0085] Among them, an intermediate channel needs to be set at the middle position of the column adapter to allow the cable connected to the electrical connection terminal to pass through. The screws for fixedly connecting the column adapter and the base need to pass through the electrical connection terminal. Therefore, this screw needs to be arranged outside the electrical connection terminal to avoid the electrical connection terminal.

[0086] The middle part of the electrical connection terminal is the electrical connection part, and no fixed connection position can be set. Therefore, the fixed connection part of the electrical connection terminal can only be set at the edge. Due to the setting of the intermediate channel of the column adapter, the connection position between the column adapter and the column also needs to be set towards the edge.

[0087] For this reason, the R & D personnel of this application designed to also set the fixed connection position between the column adapter and the column at the edge, and fixed the electrical connection terminal by adding a bracket. Among them, the bracket is higher than the fixed connection position between the column adapter and the column. The fixed connection position between the bracket and the column adapter is close to the intermediate channel, and the fixed setting between the bracket and the electrical connection terminal is at the edge of the bracket. In this way, not only can the stability of the fixed connection between the column, the column adapter and the base be ensured, but also sufficient layout space can be provided for the electrical connection terminal to ensure the reliability of the fixation of the electrical connection terminal.

[0088] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0089] In combination with Figure 1 , the embodiments of the present application provide a display device, which can be a movable display device, such as a smart screen, a girlfriend machine, etc.

[0090] The display device according to the embodiments of the present application includes a display component 10, and the display component 10 is configured to display image information such as text and images. The display component 10 can be a liquid crystal display component 10, an OLED display component 10, a laser display component 10, etc.

[0091] The display component 10 may include a display panel, and the display panel is configured to display image information such as text and images.

[0092] The display component 10 may include a touch panel, and the touch panel is configured to recognize the operations of the user on the screen and realize the interaction with the device.

[0093] In some embodiments, in combination with Figure 2 , the display device includes a base assembly 30, and the base assembly 30 serves as the base 400 of the display device. The base assembly 30 may include a plurality of rollers 31 so that the display device can be moved.

[0094] Exemplarily, in combination with Figure 2 , the base assembly 30 is provided with five rollers 31, and the five rollers 31 are arranged at intervals around the edge of the base assembly 30, which can not only ensure the reliability of the support for the display device, but also ensure the smoothness of the movement.

[0095] The display device further includes a connection component 20, and the connection component 20 connects the base assembly 30 and the display component 10 so that the display component 10 has a certain height.

[0096] Among them, the connection component 20 and the display component 10 can be connected through a rotation component, and the rotation component is configured to adjust the pitch angle of the display component 10, and the rotation component is also configured to adjust the rotation angle of the display component 10 around the vertical direction to improve the flexibility of the user's use angle.

[0097] In some embodiments, in combination with Figure 1, the connecting component 20 includes a connecting rod 100 which has a first end and a second end along its extending direction. The first end of the connecting rod 100 is configured to be connected to the display component 10, and the second end of the connecting rod 100 is configured to be connected to the base component 30.

[0098] The connecting rod 100 can be a single rod body with a simple structure. The connecting rod 100 can also be a telescopic rod to facilitate adjusting the height of the display component 10.

[0099] The cross-section of the connecting rod 100 can be circular, oval or polygonal, etc. Exemplarily, the connecting rod 100 is a cylindrical rod.

[0100] As shown in Figure 3 and Figure 4 , a first channel 101 is provided inside the connecting rod 100. The first channel 101 can not only provide a threading space for the connecting cables of the electrical components in the display component 10 and the base component 30, but also be provided with other support structures. For example, a gas spring is provided inside the first channel 101 to enhance the supporting effect on the display component 10.

[0101] In some embodiments, with continued reference to Figure 5 , the connecting component 20 further includes an adapter 200 which is used to connect the connecting rod 100 and the base component 30.

[0102] The cross-sectional shape of the adapter 200 is the same as that of the connecting rod 100, so as to facilitate the insertion of the adapter 200 into the inside of the connecting rod 100 and improve the connection stability between the adapter 200 and the connecting rod 100. Exemplarily, the cross-sections of both the adapter 200 and the connecting rod 100 are circular.

[0103] As Figure 4 shown, the adapter 200 is provided with a second channel 201 which is configured to thread the cable. The cross-sectional shape of the second channel 201 can be circular, which is convenient for processing and threading the cable.

[0104] Generally, the connecting rod 100 has a relatively long length, and it is difficult to process a structurally complex adapter 200 at its end. Therefore, by adding an adapter 200 between the connecting rod 100 and the base component 30, the adapter 200 has a shorter length and is convenient for processing and forming. In this way, not only can the connection between the connecting rod 100 and the base component 30 be realized, but also the processing difficulty of the connecting rod 100 can be reduced.

[0105] In some embodiments, when the adapter 200 is fixedly connected to the base assembly 30 and the connecting rod 100 respectively, a part of the structure of the adapter 200 is accommodated in the first channel 101 of the connecting rod 100, and another part of the structure of the adapter 200 is accommodated in the space within the base assembly 30. The base assembly 30 and the connecting rod 100 are in direct contact, hiding the adapter 200 inside the connecting rod 100 and the base assembly 30, thereby improving the aesthetics of the appearance of the display device.

[0106] Combined with Figure 6 and Figure 7 , a first connection hole 210 is formed on the end face of the adapter 200 facing away from the connecting rod 100. The first connection hole 210 is used to achieve the fixed connection with the base assembly 30.

[0107] The first connection hole 210 can extend along the length direction of the adapter 200 to increase the axial length of the first connection hole 210, which is beneficial to increasing the mating length with the fastener, and thus improving the connection stability.

[0108] In some embodiments, multiple first connection holes 210 are provided, and the multiple first connection holes 210 are arranged at intervals along the circumferential direction of the adapter 200 to improve the reliability of the connection between the adapter 200 and the base assembly 30.

[0109] Exemplarily, the multiple first connection holes 210 are arranged at uniform intervals along the circumferential direction of the adapter 200 to improve the circumferential force balance when the adapter 200 is connected to the base assembly 30.

[0110] Exemplarily, four first connection holes 210 are provided, and the four first connection holes 210 are arranged at uniform intervals along the circumferential direction of the adapter 200. While ensuring the reliability of the fixed connection between the adapter 200 and the base assembly 30, it can also avoid affecting the arrangement of other connection holes due to setting too many first connection holes 210.

[0111] Continuing to refer to Figure 6 , a first recess 220 is formed on the end face of the adapter 200 facing away from the connecting rod 100. One end of the first recess 220 facing away from the connecting rod 100 has an opening. The first recess 220 can be a groove provided on the end face of the adapter 200 facing away from the connecting rod 100. When the display device is placed on the ground, the opening of the first recess 220 faces downward. By providing the first recess 220, connection holes at different positions are formed in the length direction of the adapter 200.

[0112] The end face of the adapter 200 facing away from the connecting rod 100 includes two parts, one part is provided with the first connection hole 210, and the other part is used to form the first recess 220.

[0113] A second connection hole 221 is formed on the bottom wall of the first recess 220. The second connection hole 221 is used to fixedly connect the adapter 200 and the first electrical connector 300. The first electrical connector 300 is used to be electrically connected to the second electrical connector 500 in the base assembly 30, so as to realize the electrical connection between the display component 10 and the electrical components in the base assembly 30.

[0114] The second connection hole 221 can extend along the length direction of the adapter 200 to increase the axial length of the second connection hole 221, which is beneficial to increasing the mating length with the fastener, and further improving the connection stability.

[0115] In some embodiments, the aperture of the second connection hole 221 is smaller than that of the first connection hole 210, that is, the aperture of the first connection hole 210 is larger than that of the second connection hole 221. In this way, by setting a larger aperture for the first connection hole 210, the stability of the fixed connection between the adapter 200 and the base assembly 30 can be ensured.

[0116] Relative to the need for a large fixed connection force between the adapter 200 and the base assembly 30, the required fixed connection force between the second electrical connector 500 and the adapter 200 is smaller. Therefore, the aperture of the second connection hole 221 is smaller, which can meet the fixed connection between the second electrical connector 500 and the adapter 200 and can also be arranged within a limited space.

[0117] In some embodiments, a plurality of second connection holes 221 are provided, and the plurality of second connection holes 221 are arranged at intervals along the circumferential direction of the adapter 200. Exemplarily, four second connection holes 221 are provided.

[0118] In some embodiments, the fixed end of the first electrical connector 300 is rectangular, and the plurality of second connection holes 221 are respectively arranged at both ends in the length direction of the first electrical connector 300, which can not only provide a layout space but also ensure the installation stability of the second electrical connector 500.

[0119] Exemplarily, the plurality of second connection holes 221 are symmetrically arranged at both ends in the length direction of the first electrical connector 300, improving the uniformity of the forces at both ends in the length direction of the first electrical connector 300.

[0120] As Figure 6 shown, a second recess 230 is formed on the bottom wall of the first recess 220. The second recess 230 can be a groove opening away from the connecting rod 100. In this way, along the length direction of the adapter 200, the connection positions formed by the second recess 230 are different from the connection positions on the second recess 230.

[0121] The bottom wall of the first recess 220 includes two parts. One part is provided with the second connection hole 221, and the other part is used to form the second recess 230.

[0122] A third connection hole 231 is provided on the bottom wall of the second recess 230. The third connection hole 231 is used to realize the fixed connection between the adapter 200 and the connecting rod 100.

[0123] The third connection hole 231 can extend along the length direction of the adapter 200 to increase the axial length of the third connection hole 231, which is beneficial to increasing the mating length with the fastener, and thus improving the connection stability.

[0124] In some embodiments, the aperture of the third connection hole 231 is larger than that of the second connection hole 221. In this way, the larger aperture of the third connection hole 231 is beneficial to ensuring the stability of the fixed connection between the adapter 200 and the connecting rod 100.

[0125] In some embodiments, the aperture of the third connection hole 231 can be the same as that of the first connection hole 210. In this way, the fasteners used for connecting the adapter 200 with the connecting rod 100 and the base assembly 30 are the same, which is not only convenient for assembly, but also can make the circumferential force on the adapter 200 more balanced, and is beneficial to improving the stability of the structure of the display device.

[0126] In some embodiments, a plurality of third connection holes 231 are provided, and the plurality of third connection holes 231 are arranged at intervals along the circumferential direction of the adapter 200 to improve the reliability of the connection between the adapter 200 and the connecting rod 100.

[0127] Exemplarily, the plurality of third connection holes 231 are arranged at uniform intervals along the circumferential direction of the adapter 200 to improve the circumferential force balance when the adapter 200 is connected to the connecting rod 100.

[0128] Exemplarily, three or four third connection holes 231 are provided, and the three or four third connection holes 231 are arranged at uniform intervals along the circumferential direction of the adapter 200. While ensuring the reliability of the fixed connection between the adapter 200 and the connecting rod 100, it can also avoid affecting the arrangement of other connection holes due to setting too many third connection holes 231.

[0129] In some embodiments, the plurality of first connection holes 210 and the plurality of third connection holes 231 are arranged alternately at intervals along the circumferential direction of the adapter 200. With such an arrangement, the fixed connections between the adapter 200 and the connecting rod 100 and the base assembly 30 at its two ends are arranged alternately, which can not only ensure the reliability of the connection between the adapter 200 and the connecting rod 100 and the base assembly 30, but also be beneficial to improving the uniformity of the force on the adapter 200 and reducing the influence of uneven force on the service life of the adapter 200.

[0130] For each of the above connection holes, a fastener is inserted therein for realizing the fixed connection between the adapter 200 and other components. The fastener can be a screw, a stud and a nut, a pin, etc. In the embodiment of the present application, the fastener is taken as an example of a screw for illustration, and the connection method is simple and stable.

[0131] Moreover, in order to improve the stability of the screw connection, a gasket is also provided at the head of the screw, such as a flat gasket, a spring washer, etc.

[0132] Among them, a first fastener is inserted through the first connection hole 210, and the adapter 200 is fixedly connected to the base assembly 30 through the first fastener.

[0133] A second fastener 620 is inserted through the second connection hole 221; as Figure 4 and Figure 5 shown, the connection assembly 20 further includes a first electrical connector 300, and the first electrical connector 300 is fixed to the adapter 200 through the second fastener 620. The cable connected to the first electrical connector 300 is electrically connected to the display component 10 through the second channel 201 and the first channel 101.

[0134] A third fastener 630 is inserted into the third connection hole 231, and the adapter 200 is fixedly connected to the connecting rod 100 through the third fastener 630.

[0135] Combined with Figure 8 , in some embodiments, the first electrical connector 300 includes a first bracket 310, and the first bracket 310 is fixedly connected to the adapter 200 through the second fastener 620.

[0136] The projection of the first bracket 310 on the end face of the adapter 200 and the third connection hole 231 at least partially overlap. Thus, when the first bracket 310 is fixed to the adapter 200, looking from the end face of the adapter 200 facing away from the connecting rod 100 towards the first recess 220, the first bracket 310 blocks a part of the third fastener 630.

[0137] Since the third fastener 630 is located in the second recess 230, the third fastener 630 does not affect the arrangement of the first bracket 310. Thus, the first bracket 310 can increase the fixing position at a position different from the third fastener 630, expand the fixing area, and provide a sufficient fixing area for the fixing of the electrical connection base.

[0138] In some embodiments, the first electrical connector 300 further includes a first electrical connection base 320, and the first electrical connection base 320 is configured to be electrically connected to the second electrical connector 500. The first electrical connection base 320 is fixedly connected to the first bracket 310.

[0139] In some embodiments, a wire threading channel 315 is provided on the first bracket 310 to allow the cable connected to the first electrical connection base 320 to pass through. The wire threading channel 315 communicates with the second channel 201, and the cable connected to the first electrical connection base 320 is electrically connected to the display component 10 through the wire threading channel 315, the second channel 201, and the first channel 101.

[0140] A fifth connection hole 313 is provided on the first bracket 310. The number of the fifth connection holes 313 is the same as that of the second connection holes 221, and each fifth connection hole 313 is coaxially arranged with one of the second connection holes 221; the second fastener 620 passes through the fifth connection hole 313 and the second connection hole 221 to realize the fixed connection between the first bracket 310 and the adapter 200.

[0141] In some embodiments, the first bracket 310 is generally rectangular. The first bracket 310 has two ends opposite and spaced apart in the first direction, and the second bracket 510 also has two ends opposite and spaced apart in the second direction. The dimension of the first bracket 310 in the first direction is greater than the dimension in the second direction, and the second direction is perpendicular to the first direction.

[0142] Since the wire threading channel 315 is provided on the first bracket 310, the space of the first bracket 310 in the second direction is limited. Therefore, the fifth connection holes 313 are provided on both sides of the wire threading channel 315 in the first direction.

[0143] Exemplarily, two fifth connection holes 313 are respectively provided on both sides of the wire threading channel 315 in the first direction, and the two fifth connection holes 313 are spaced apart in the second direction.

[0144] Continue to refer to Figure 9 , in some embodiments, a third recess 311 is provided on the first bracket 310. The second fastener 620 is received in the third recess 311, and the second fastener 620 fixedly connects the third recess 311 and the adapter 200. The third recess 311 may be a groove provided on the first bracket 310, and the groove opens towards the base assembly 30.

[0145] In this way, the fifth connection holes 313 are provided on the bottom wall of the third recess 311. By providing the third recess 311 to receive the second fastener 620, it is avoided that the second fastener 620 protrudes from the surface of the first bracket 310 and affects the fixation of the first electrical connection base 320.

[0146] In some embodiments, a fourth connection hole 312 is further provided on the first bracket 310. A fourth fastener passes through the fourth connection hole 312, and the first electrical connection base 320 is fixedly connected to the first bracket 310 through the fourth fastener.

[0147] The projections of the fourth fastener and the second recess 230 on the end face of the adapter 200 at least partially overlap, so that the fourth fastener is not affected by the third fastener 630 in the second recess 230.

[0148] The fourth connection hole 312 is offset from the third recess 311 to avoid interference between the installation of the first electrical connection base 320 and the second fastener.

[0149] In the embodiment of the present application, by providing the fourth connection hole 312 on the first bracket 310 and the fourth fastener passing through the fourth connection hole 312, the first bracket 310 and the first electrical connection base 320 are fixedly connected, and the connection method is stable and reliable.

[0150] Since the size of the first electrical connection base 320 is relatively large, the fourth connection hole 312 can be located on the side of the fifth connection hole 313 away from the wire threading channel 315, and there is sufficient layout space for the fourth connection hole 312.

[0151] In some embodiments, a plurality of fourth connection holes 312 are provided, and the plurality of fourth connection holes 312 are arranged at intervals around the wire threading channel 315. With this arrangement, the stability and reliability of the fixed connection between the first electrical connection base 320 and the first bracket 310 are improved.

[0152] The plurality of fourth connection holes 312 are respectively provided on both sides of the wire threading channel 315 along the first direction, and there is sufficient layout space.

[0153] Exemplarily, the plurality of fourth connection holes 312 are symmetrically arranged about the midline of the wire threading channel 315. The midline of the wire threading channel 315 extends along the second direction and passes through the center of the wire threading channel 315. This is beneficial to improving the balance of forces on both sides of the first bracket 310 of the wire threading channel 315.

[0154] Exemplarily, four fourth connection holes 312 are provided, and two fourth connection holes 312 are respectively provided on both sides of the wire threading channel 315 along the first direction, and the two fourth connection holes 312 on the same side are arranged at intervals along the second direction. In this way, the four fourth connection holes 312 are arranged in a rectangular matrix on the first bracket 310, which can not only improve the stability of the fixation of the first electrical connection base 320, but also improve the uniformity of the force on the first bracket 310.

[0155] In some embodiments, a groove portion is provided in the first recess 220, and the shape of the groove portion matches the shape of the first bracket 310, which is convenient for the positioning and installation of the first bracket 310.

[0158] Among them, when the first positioning portion 314 is a protruding structure, such as a protruding column, a protruding block, etc.; the second positioning portion 222 is a recessed structure that cooperates with the protruding structure, such as a hole, a groove, etc. Or, when the first positioning portion 314 is a recessed structure, such as a hole, a groove, etc.; the second positioning portion 222 is a protruding structure that cooperates with the recessed structure, such as a protruding column, a protruding block, etc.

[0159] Continue to refer to Figure 3 and Figure 4 , in some embodiments, a sixth connection hole 111 is provided in the connecting rod 100, and the third fastener 630 passes through the third connection hole 231 and the sixth connection hole 111 to realize the fixed connection between the connecting rod 100 and the adapter 200.

[0160] The number of the sixth connection holes 111 is the same as the number of the third connection holes 231, and each sixth connection hole 111 is coaxial with one of the third connection holes 231, so that the third fastener 630 can pass through the third connection hole 231 and the sixth connection hole 111, improving the connection stability between the connecting rod 100 and the adapter 200.

[0161] In some embodiments, a protruding portion 110 is provided on the side wall of the first channel 101 of the connecting rod 100. The protruding portion 110 protrudes toward the center of the first channel 101, and a sixth connection hole 111 is provided on the protruding portion 110.

[0167] In some embodiments, the stopper 241 includes an inner side wall, an outer side wall and a bottom side wall. When the stopper 241 is accommodated in the second notch 240, the bottom side wall is flush with the second recessed portion 230, and a first fixing hole is provided on the bottom side wall. The sixth connecting hole 111 of one of the protruding portions 110 of the connecting rod 100 is opposite to the first fixing hole, and a fastener is provided through the first fixing hole and the sixth connecting hole 111, so that the stopper 241 is fixed to the connecting rod 100.

[0168] The inner side wall and the outer side wall are relatively arranged on the inner side and the outer side of the bottom side wall, and both are located on the side of the bottom side wall away from the protrusion 110. The inner side wall is flush with the first recessed portion 220 or lower than the first recessed portion 220, and together with the adapter 200, forms the second channel 201 to prevent the inner side wall from affecting the fixation of the first electrical connection seat 320. The outer side wall is flush with the end face of the adapter 200 away from the connecting rod 100, which is conducive to ensuring the appearance of the end of the adapter 200.

[0169] Through the above configuration, the connection assembly 20 can be assembled in the following manner:

[0170] The cable of the first electrical connection socket 320 passes through the wire passage 315 of the first bracket 310 , and is connected to the cable passing through the first passage 101 through the second notch 240 .
