[0036] In order to make the purpose, technical solution and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the utility model. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Compared with the embodiments shown in the drawings, feasible implementations within the scope of protection of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0039] The utility model provides a conductive terminal structure that can rotate at a large angle, which is used in the electrical connection process between terminals. The utility model does not limit the installation angle of the matching power supply, but the conductive terminal structure that can rotate at a large angle is particularly suitable for handheld vacuum cleaners.

[0040] In general, the conductive terminal structure capable of large-angle rotation proposed by the present invention mainly comprises an insertion end 1, a connection end 2 and a connection terminal. Figure 1 , which shows the arrangement relationship among the insertion end 1, the connection end 2 and the connection terminal.

[0041] In order to achieve the purpose of quick adaptation and installation with the terminal, the problem that the main structure of the existing handheld vacuum cleaner in the background technology uses a conventional plug-in terminal inside the wire terminal, which limits the installation angle of the matching structure and the type of connecting structural parts, and also limits the user's insertion angle. The cable can only be inserted from one angle or needs to repeatedly try different angles and positions until the correct insertion angle is found, increasing the risk of cable damage; in addition, it also leads to the inability to achieve good compatibility with other types of power adapters, reducing the versatility and flexibility of the product. For this reason, in the technical solution provided in this embodiment, a wire terminal with a rotatable snap-on structure with an L-shaped connecting groove 4 is used in the handheld vacuum cleaner, so that the accessories can be quickly aligned and installed at unconventional angles, and the terminal can be easily withdrawn by rotating in the connecting groove 4. The operation is simple, but can achieve the purpose of quick alignment and withdrawal, thereby improving the adaptability and compatibility of the handheld vacuum cleaner with the accessories.

[0042] like Figure 1As shown, the conducting terminal includes an insertion end 1 and a connection end 2 which are integrally arranged in a stepped shape along the axial direction, and a connection terminal installed in the insertion end 1 and the connection end 2. The corresponding connection terminals of the insertion end 1 and the connection end 2 are provided with a communicating through groove 3 in the direction of connecting the positive pole and the negative pole. The insertion end 1 and the connection end 2 are symmetrically centered with the positive pole and the negative pole, and an insulating layer 5 is provided in the middle position to achieve the effect of separation. When the connection terminal is inserted into the through groove 3 during use, the part located at the connection end 2 forms a main contact 9 connected to the corresponding accessory, while the part located at the insertion end 1 realizes wiring.

[0043] It should be specifically explained that, in order to achieve rapid alignment and installation of accessories without being affected by the installation angle, a connecting groove 4 is provided on the side of the connecting end 2 away from the insertion end 1 in the present embodiment. On the one hand, the interior of the connecting groove 4 is connected to the through groove 3, and on the other hand, the connecting groove 4 is arranged to be L-shaped, including a horizontal end and a vertical end, wherein the outer side openings of the horizontal end and the vertical end are arranged flush with the top and side surfaces of the connecting end 2, which makes it convenient to achieve the effect of clamping from the top, top and side, or side of the connecting groove 4.

[0044] Furthermore, chamfers 6 are provided at the entrances of the horizontal and vertical ends of the connecting groove 4. The chamfers can make the corners smooth, soft and rounded, making it convenient to adjust the angles from the top of the connecting groove 4, between the top and the side, and between the side, so as to achieve quick installation and docking.

[0045] On this basis, in order to facilitate the rapid and accurate installation of the connection terminal 2, the connection terminal is configured to include a connection terminal body 7, a plug terminal 8, a main contact 9, a transition zone 10 and a wiring terminal, wherein the connection terminal body 7 extends toward the connection terminal 2 and forms an arc-shaped plug terminal 8, and the other end forms a transition zone 10 along a side away from the plug terminal 8, and a side of the transition zone 10 away from the plug terminal 8 is integrally provided with a wiring terminal and a circuit connection with the main structure of the vacuum cleaner;

[0046] Next, considering the circuit continuity of the accessory clamping process, a group of plug terminals 8 are relatively symmetrically arranged. Since the main contact 9 is formed at the highest arc point of the plug terminal 8, a pair of main contacts 9 are arranged close to each other. In the top view, the main contacts 9 are arranged in the through slot 3, and the gap between the main contacts 9 is reduced, which can ensure the connection strength between the accessories and the accessories, and will not be affected by the installation angle; wherein the top of the main contact 9 is provided with a cutting angle 12, so that the accessories inserted from the top can be installed quickly and accurately, and for the accessories inserted from the side, since the side surfaces of the pair of main contacts 9 are arc-shaped structures, the above effect can also be achieved;

[0047] As mentioned above, the connection terminal is also provided with a transition zone 10, wherein the transition zone 10 is provided between the insertion end 1 and the connection end 2, and the connection terminal body 7 is provided with a baffle 11 at the top of the transition zone 10. Since the connection between the insertion end 1 and the connection end 2 is in a stepped structure, the internal structure is also corresponding, so as to prevent the connection terminal from shifting after installation, the baffle 11 and the insertion end 1 play a limiting role on the internal structure;

[0048] like Figure 3 As shown, the structure that plays a corresponding role with the baffle 11 is that the insertion end 1 is located at the top of the transition zone 10 and the wiring terminal and is provided with an openable and closable top cover 15, and the top cover 15 is locked on the side of the insertion end 1 by a snap. In addition, the top cover 15 can also be opened when the circuit of the vacuum cleaner main structure is connected to reduce the difficulty of installation, and closed after installation to play the role of wire pressing and protection; further, in the connection structure with the vacuum cleaner main structure, the feeding end adopts an open-tube structure 13 or a feeding terminal 14 structure, and the feeding terminal 14 is tilted and faces 45° upward to adapt to different internal structure requirements.

[0049] like Figure 6 As shown, the conductive terminal that can be rotated at a large angle is installed on the handheld vacuum cleaner. When in use, the connecting end 2 of the conductive terminal that can be rotated at a large angle can be equipped with matching accessories and be conductive within a range of 90° from the horizontal end to the vertical end of the connecting groove 4.

[0050] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
