Description

Technical Field

[0001] The utility model relates to the technology of power strips, in particular to a power strip. Background Art

[0002] There are two main structures of power strips on the market:

[0003] 1. The socket inner frames are separately arranged, and a group of sockets (for example, two holes as a group or three holes as a group) are separately arranged on a socket inner frame. In this way, a number of socket inner frames are arranged inside the power strip shell; for example, CN217656119U discloses a power strip shell structure and a power strip structure, wherein the power strip structure includes a power strip shell, a plurality of sockets, a control switch and a wiring socket, and the sockets are installed in the corresponding first mounting holes. Since a plurality of sockets need to be configured, it is troublesome to assemble a plurality of parts one by one and to install and position these sockets. In addition, additional wires are required between the plurality of sockets to form an electrical connection, and the wiring operation is also troublesome.

[0004] 2. A socket bracket portion is formed in the socket bottom shell, and a conductive terminal is installed on the socket bottom shell. For example, CN217934279U discloses a socket for a wireless power strip and a wireless power strip. The socket for the wireless power strip includes an L-pole socket, an N-pole socket and an E-pole socket. The E-pole socket is located between the L-pole socket and the N-pole socket. The L-pole socket includes an integrally formed L-pole socket body, an L-pole socket tongue and an L-pole socket body, and the L-pole socket tongue is connected to the side of the L-pole socket body; the N-pole socket includes an integrally formed N-pole socket body, an N-pole socket tongue and an N-pole socket body, and the N-pole socket tongue is connected to the side of the N-pole socket body; the E-pole socket includes an integrally formed E-pole socket body, an E-pole socket tongue and an E-pole socket body, and the E-pole socket tongue is connected to the end of the E-pole socket body.

However, the structure of the bottom shell of each socket is relatively complex and the production difficulty is relatively high. For power strip products, the overall production efficiency is not ideal.

The cover bodies 24 are correspondingly located at the bottom of the socket main frame 21. The bottom of the cover body 24 is provided with a positioning hole 26, and the inner bottom of the shell 10 is provided with a corresponding positioning column 15. The socket module 20 is placed inside the shell 10, and the positioning column 15 is embedded in the corresponding positioning hole 26.

[0065] like Fig. 8A As shown, the conductive metal strip includes a substrate a1 and a side panel a2; the substrate a1 is extended forward and backward, and some positioning holes and / or process holes are usually provided on the substrate a1; one end of the side panel a2 is connected to one side of the substrate a1; the side panel a2 is extended forward and backward along the side edge of the substrate a1, and the side panel a2 maintains a distance from the substrate a1; the side panel a2 is provided with at least a first bending point b1, a second bending point b2 and a third bending point b3 which are arranged at a distance along the front-to-back direction, the side panel a2 is bent outward at the first bending point b1, and is bent inward at the second bending point b2, and is bent inward at the third bending point b3, so that: a U-shaped conductive clip c is bent on the side panel a2. The side panel a2 is also provided with a fourth bend b4, and the fourth bend b4 is located in front of the first bend b1, and the side panel a2 is bent upward or downward at the fourth bend b4. In actual design, the side panels a2 are respectively connected to the left and right sides of the substrate a1, and more than two side panels a2 on the left or right side of the substrate a1 are arranged at intervals in the front-to-back direction, so that: the conductive terminal has a plurality of U-shaped conductive clips c. Through the bending structure design of the conductive metal strip, the overall width of the terminal material is narrower, saving the metal sheet material, and the contact area of ​​the conductive clip c can be made larger, which is conducive to improving the reliability of the conductive contact.

[0066] Specifically, the side panel a2 includes a transverse extension portion a21 and a longitudinal extension portion a22; one end of the transverse extension portion a21 is integrally connected to one side of the substrate a1, and the other end of the transverse extension portion a21 extends outward away from the substrate a1; the front end of the longitudinal extension portion a22 is connected to the other end of the transverse extension portion a21, and the rear end of the longitudinal extension portion a22 extends backward beside the substrate a1; the first bending point b1, the second bending point b2 and the third bending point b3 are arranged on the longitudinal extension portion a22, and the fourth bending point b4 is arranged on the transverse extension portion a21. The substrate a1 and the side panel a2 are integrally punched and bent parts of the same metal plate; the plate thickness direction of the substrate a1 is the up-down direction; the plate thickness direction of the portion of the lateral extension portion a21 corresponding to the fourth bending point b4 close to one end of the lateral extension portion a21 is the up-down direction, that is: the thickness direction of the portion of the lateral extension portion a21 located between one end of the lateral extension portion a21 and the fourth bending point b4 is the up-down direction; after the side panel a2 is bent upward or downward at the fourth bending point b4, the plate thickness direction of the portion of the lateral extension portion a21 corresponding to the fourth bending point b4 away from one end of the lateral extension portion a21 is the left-right direction; therefore, the plate thickness direction of the conductive clip c is the defined horizontal direction. The longitudinal extension part a22 includes a longitudinal connecting strip a221 and two clips a222; the front end of the longitudinal connecting strip a221 is integrally connected to the other end of the transverse extension part a21, and the rear end of the longitudinal connecting strip a221 extends backward from the side of the substrate a1; when not bent, the distance between the longitudinal connecting strip a221 and the side of the substrate a1 is usually the left and right width of the transverse extension part a21; the clip a222 is integrally connected to the inner side of the longitudinal connecting strip a221, and the two clips a222 maintain a front-to-back distance; after bending, the two clips a222 are arranged on opposite sides to form a clamping groove a223. In order to improve the reliability of clamping contact, usually, one of the clips a222 or two of the clips a222 are contact springs protruding toward the clamping groove. When not bent, the front-to-back length value L1 of the clip a222 is greater than the left-to-right width value L2. Sufficient dimensions in the front-to-back direction are used to design the front-to-back length L1 of the clip. Therefore, on a metal plate with a sufficiently narrow left-right width, the clip can still freely and flexibly set a sufficient front-to-back length to meet the contact area requirements and improve contact reliability.

[0067] It should be noted that the conductive terminal can adopt the side plate a2 structure described above on one side or both sides, such as Figure 1-6As shown, it shows an embodiment in which the side plate a2 structure described above is adopted on both sides. If the side plate a2 structure described above is designed only on one side of the substrate a1, the side plate a2 and the conductive clip may not be provided on the other side, or as shown in FIG. Figures 7 to 9 As shown, other structural forms of side panels a2' may be provided on the other side, which are not listed one by one in this article.

[0068] Part or all of the conductive metal strips of the power strip may adopt this bending structure, and the overall width of the terminal material is narrower, saving metal sheet materials. Moreover, the contact area of ​​the conductive clip c can be made larger, which is beneficial to improving the reliability of conductive contact.

[0069] Next, a manufacturing process of a power strip is provided. The power strip is any of the power strips described above. The manufacturing process comprises the following steps:

[0070] Step 1, respectively prepare a housing and a socket module; wherein the insulating inner frame and the insulating bottom cover of the socket module are respectively formed by injection molding, and the conductive metal strip is cut into corresponding lengths on the continuous terminal strip as required; when assembling the socket module, the conductive metal strip is installed into the insulating inner frame, and then the insulating bottom cover is assembled to the bottom of the insulating inner frame;

[0071] Step 2: Install the socket module in the housing.

[0072] Specifically, a feasible assembly process of the power strip of Embodiment 1 is introduced:

[0073] (1) A bottom shell 101, a front shell 102, a socket module 20, a switch assembly 30, and a USB interface assembly 40 are respectively manufactured; wherein the bottom shell 101 and the front shell 102 are respectively manufactured by injection molding; the insulating inner frame 201, the insulating bottom cover 203, and the jack partition panel 204 of the socket module 20 are respectively manufactured by injection molding, and the insulating inner frame 201 and the insulating bottom cover 203 are manufactured by continuous injection molding and cut according to the required number of groups. A long thin plate-like insulating material piece (having a certain hardness and being able to meet the cutting requirements) can be preset in advance, and the long thin plate-like insulating material piece passes through the injection mold, and a plurality of socket main frames (or cover bodies) are injection molded on the long thin plate-like insulating material piece. This continuous injection molding method is the same / similar to the method of injection molding the plastic part on the metal strip commonly used in the industry, and the main difference is that the metal strip is replaced with a long thin plate-like insulating material piece. Of course, the insulating inner frame 201 and the insulating bottom cover 203 can also design the injection mold as a common mold within the set N group number range. For example, the accessories in the injection mold are designed as more than two independent modules: a first module, a second module, a third module, and so on. If the insulating inner frame to be injection molded has two groups of socket main frames, it can be achieved by using the first module (baffles are provided at both ends of the first module); if the insulating inner frame to be injection molded has three groups of socket main frames, it can be achieved by using the first module in combination with the second module (baffles are respectively provided at one outer end of the first module and one outer end of the second module, and the adjacent ends of the two are connected to form a cavity that can be used to injection mold an insulating inner frame with two groups of socket main frames as one body); if the insulating inner frame to be injection molded has four groups of socket main frames, it can be achieved by using the first module in combination with the second module and the third module (similarly, adjacent modules are connected, and baffles are provided at the two outermost ends to form a cavity that can be used to injection mold an insulating inner frame with three groups of socket main frames as one body). Similarly, the insulating bottom cover can also be molded in the same way. The conductive metal strip 202 can be made of a continuous long strip of conductive metal strip 202 material, and the corresponding length can be cut as needed. When assembling the socket module 20, one of the conductive metal strips 202 is inserted into the top of the mounting groove 28 of the insulating inner frame 201, and the other conductive metal strip 202 is inserted into the bottom of the mounting groove 28 of the insulating inner frame 201. Then, the insulating bottom cover 203 is assembled to the bottom of the insulating inner frame 201, and the buckle portion 12 is stuck in the corresponding buckle hole 27 to achieve the installation and positioning of the insulating bottom cover 203 at the bottom of the insulating inner frame 201. In addition, the jack partition panel 204 is assembled to the top of the socket main frame 21, and the hinge shaft 5 extends into the hinged movable groove 6 of the socket main frame 21. The limit portion 7 at the other end is also stuck under the anti-detachment portion 8 of the socket main frame 21.

[0074] (2) The switch assembly 30, the USB interface assembly 40 and the socket module 20 are respectively installed in the bottom shell 101. The bottom shell 101 is provided with installation positions for the switch assembly 30, the USB interface assembly 40 and the socket module 20, so that these switch assembly 30, the USB interface assembly 40 and the socket module 20 are placed in the corresponding installation positions and positioned. A partition wall 16 is provided between the installation position of the USB interface assembly 40 and the installation position of the socket module 20. The socket module 20 is placed in the corresponding installation position, and the positioning column 15 provided on the inner bottom of the shell 10 is embedded in the bottom positioning hole 26 of the socket module 20, so that the socket module 20 is reliably installed and positioned inside the shell 10.

[0075] (3) Assemble the front shell 102 onto the bottom shell 101 , and the buckle 12 of the bottom shell 101 hooks the clamping hole 14 of the front shell 102 , so that the front shell 102 and the bottom shell 101 are assembled and positioned.

[0076] like Figures 11 to 14 As shown, it shows the structure of the socket module of the second embodiment. The structure of the second embodiment is basically the same as that of the first embodiment, and the main difference is that:

[0077] 1. The two conductive metal strips 202 of the second embodiment are respectively installed at the left and right sides of the insulating inner frame 201, and the positions of the two conductive metal strips 202 are separated and positioned by using the left and right sides of the socket main frame 21 itself, and the insulation separation effect is ideal. Specifically, upper convex ribs 211 are provided on the left and right sides of the socket main frame 21 itself, and the bottom ends of the upper convex ribs 211 are used as the upper positioning surfaces of the conductive metal strips 202, and lower convex ribs 241 are provided on the left and right sides of the cover body 24, and the cover body 24 limits the lower side of the conductive metal strip 202, and the lower convex ribs 241 limit the outer side of the conductive metal strip 202. In this way, the conductive metal strip 202 is installed on the insulating inner frame 201, and the upper side of the conductive metal strip 202 is limited by the bottom end (upper positioning surface) of the upper convex rib 211. Then the insulating bottom cover 203 is assembled to the bottom of the socket main frame 21. The cover body 24 limits the lower side of the conductive metal strip 202, and uses the lower convex rib 241 to block the outer side of the conductive metal strip 202 to limit the outer side of the conductive metal strip 202.

[0078] 2. Embodiment 2 is provided with five groups of jacks, and each group of jacks includes two jacks, while embodiment 1 is provided with three groups of jacks, one group of jacks includes two jacks arranged side by side and three jacks arranged in a triangle. In actual design, the number of jack groups and the arrangement of jacks in each group are not limited to embodiment 1 and embodiment 2.

[0079] like Figures 15 to 19EAs shown, it shows the structure of the socket module of Example 3. The structure of Example 3 is basically the same as that of Example 1, and the main difference is that in Example 3, three conductive metals are provided, including a neutral wire, a live wire and a ground wire, that is, on the basis of Example 1, a ground wire is also included. In actual layout, the ground wire can be installed on the left or right side of the insulating inner frame.

[0080] Referring to the first and third embodiments, in actual production, for sockets of the same specification (for example, the arrangement of each group of jacks in the first and third embodiments is the same) and with different numbers of groups, they can be produced in common mode, and according to the length and requirements of the strip, the number of groups of jacks to be designed can be cut accordingly (the dotted line indicates the approximate position of the cut-off line). FIG. 19A to FIG. 19E As shown, the insulating inner frame 201, the live wire conductive metal strip 2021, the neutral wire conductive metal strip 2022, the ground wire conductive metal strip 2023, and the insulating bottom cover 203 are all in a continuous material strip during production, wherein the insulating inner frame 201 and the insulating bottom cover 203 are respectively injection molded, and a cutting machine is provided on the discharge side of the injection molding machine. For the insulating inner frame production line, the insulating inner frame 201 with the corresponding number of socket main frames 21 is cut out (for example, in the third embodiment, each insulating inner frame has 6 groups of socket main frames 21), and for the insulating bottom cover production line, the insulating inner frame 201 with the corresponding number of socket main frames 21 is cut out. The insulating bottom cover 203 has a number of cover bodies 24 (each insulating bottom cover 203 has 6 groups of cover bodies 24), and the live wire conductive metal strip 2021, the neutral wire conductive metal strip 2022, and the ground wire conductive metal strip 2023 are respectively formed by metal stamping. For example, a cutting machine can be set on the discharge side of the stamping machine to cut the live wire conductive metal strip 2021 with a corresponding number of conductive clips 1, and one end of the live wire conductive metal strip retains the first terminal after cutting, and the other end retains the second terminal after cutting (the neutral wire conductive metal strip 2022 and the ground wire conductive metal strip 2023 are the same).

[0081] like FIG. 20A to FIG. 20E As shown, if only three groups of inner jacks are provided, corresponding groups of insulating inner frames 201, live wire conductive metal strips 2021, neutral wire conductive metal strips 2022, ground wire conductive metal strips 2023, and insulating bottom covers 203 can be cut during production.

[0082] It should be noted that, for the first embodiment, a ground wire conductive metal strip may also be arranged so that a corresponding conductive terminal is provided corresponding to the ground wire jack.

[0083] The design focus of the utility model is that it mainly combines the independent modular design of the socket module and the ingenious structural design of the insulating inner frame, the conductive metal strip and the insulating bottom cover, so that different groups of requirements can be produced in the same mold. According to the length and requirements of the power strip, several groups of jacks need to be designed and then several groups are cut accordingly. The integrated molding is easy to produce, improves production efficiency and reduces production costs. Moreover, the shell structure of the power strip becomes very simple, and the shell and socket module of the power strip product can be produced separately, which is convenient for parallel production, and further helps to improve the overall production efficiency of the power strip.

[0084] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
