Description

Technical Field

[0001] The utility model relates to the technical field of power strip accessories, in particular to a power strip inner core structure. Background Art

[0002] A power strip is a multi-socket with wires that can connect more than one power plug, which saves space and wires and is an indispensable device in daily life. At present, the inner core structure of the power strip is mainly copper core, and the copper core is generally provided with multiple spring structures to cooperate with the plug-in action. In daily use, the power strip can be inserted into multiple plugs at one time, but the frequent plugging and unplugging of the plug can easily cause the copper springs in the power strip to deform, making it difficult to easily insert the plug into the power strip, or the plug is very easy to loosen after insertion.

[0003] Chinese patent CN201520804294.3 discloses a copper strip for power strips. The inner core structure used in most power strips is the same as the technical solution in the patent. The main body of the copper core is a thin strip structure, and extends into a plurality of socket structures for use with adapter plugs. Each socket structure is formed by two spring sheets. This structure causes the overall structure of the copper core to be too thin and prone to deformation, resulting in deformation and dislocation during use, which causes defects such as unsmooth, unstable, and poor contact in subsequent plug insertion. Utility Model Content

[0004] The utility model provides an inner core structure of a power strip, which can solve the problem that the copper cores of some existing power strips are easily deformed and misaligned during use due to their too thin structures.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0025] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0027] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figures 1 to 4This embodiment discloses a strip core structure, including a copper core with a longitudinal section profile of "n" shape, wherein the long side direction of the copper core is defined as the left-right direction, and the short side direction is defined as the front-back direction, such as Figure 1 As shown, in the left and right directions of the copper core, its longitudinal section profile is an "n" type structure, which can ensure that the overall copper core has better structural strength, can maintain a stable structural form, and will not be easily deformed during use.

[0029] The copper core includes a base portion 1 located in the middle, and a plug-in portion 2 is provided on each of the left and right sides of the base. The base portion 1 mainly serves to connect the left and right plug-in portions 2 and to help the copper core to be connected and fixed to the power strip housing. The base portion 1 and the plug-in portion 2 are an integrated sheet metal structure.

[0030] Further, combined with Figure 2 As shown, an extension sheet 11 is provided on one side of the base portion 1. The extension sheet 11 is a sheet-like structure that extends laterally. The extension sheet 11 and the top surface of the main body of the base portion 1 form a "T"-shaped structure, which increases the top area of ​​the base portion 1, can increase the contact area of ​​the main connection area between the copper core and the power strip shell, and improve its connection position stability. The base portion 1 is provided with a mounting hole 12 for connecting the power strip shell. The top surface of the main body of the base portion 1 and the extension sheet 11 are both provided with mounting holes 12. The mounting holes 12 are longitudinal through-hole structures. In this embodiment, there are three mounting holes 12, and the outer areas of the two mounting holes 12 located above the main body of the base portion 1 are provided with outwardly expanded edges 15. The provision of the outwardly expanded edges 15 can improve the structural stability of the mounting holes 12 at this position, avoid deformation of the sheet structure resulting in deformation of the mounting holes 12, and increase the difficulty of subsequent assembly. When in use, it is used to penetrate bolts for locking connection or for sleeve limiting columns.

[0031] Furthermore, in order to improve the anti-slip effect of the contact area between the copper core and the power strip housing, an anti-slip structure 13 is provided on the upper end surface of the extension piece 11. The anti-slip structure 13 is a plurality of evenly distributed dot-shaped flanges, which can effectively increase the friction and help reduce relative sliding between the copper core and the power strip housing during use.

[0032] Furthermore, an upwardly bent flange 14 is provided at the outer end of the extension piece 11, and the flange 14 can play a positioning role, so that the installation position of the extension piece 11 can be effectively and accurately controlled during assembly.

[0033] The plug-in part 2 is provided with a sink 21, which makes the plug-in part 2 present a "U"-shaped structure in the front-to-back direction, which enriches the structural changes of the copper core in the longitudinal direction, making its structure more stable and not easily deformed.

[0034] Combination Figures 1 to 3The sink 21 is provided with a first spring piece 22 and a second spring piece 23 which are spaced apart horizontally from front to back. The bottom of the first spring piece 22 and the second spring piece 23 are fixed ends connected to the sink 21. A plug-in gap 4 is formed between the first spring piece 22 and the second spring piece 23 for plugging in. The adjacent sides of the first spring piece 22 and the second spring piece 23 are provided with a bent structure which is close to each other. The bent structure can clamp the plug laterally after the plug is inserted. The tops of the first spring piece 22 and the second spring piece 23 are free ends forming a "V"-shaped open structure.

[0035] It should be noted that the first spring piece 22 is a sheet structure parallel to the left and right directions and the middle part thereof is bent inward in the front-to-back direction, so that the middle area is bent inward, which is conducive to the subsequent horizontal clamping of the plug after insertion. Correspondingly, the second spring piece 23 is an arc-shaped plate with a "C"-shaped cross-sectional profile, and its inner end surface forms a concave curved surface, which also makes the cross-sectional profile of the plug-in gap form a "D"-shaped structure. Compared with the traditional closed plug-in structure, this structure can have a better jack space, which can effectively reduce the resistance when the plug is inserted, and then reduce the strength of the reverse force caused by the plug on the spring piece when plugged in, thereby protecting the risk of deformation of the spring piece due to excessive force. In addition, this structure can meet the use requirements of cylindrical plugs and improve the adaptability of the slot.

[0036] In order to improve the structural toughness of the copper core, a hollow structure 3 is provided on the top of the base portion 1 and the plug-in portion 2. In the present embodiment, the hollow structure 3 is a strip through-hole structure, and the long side direction of the strip through-hole structure is parallel to the front-to-back direction, which prevents the top structure of the copper core from being too rigid. While ensuring the stability of its structural strength, the top structure can be lightweight, so that the bottom of its "n"-shaped structure has better flexibility, and the free end of the bottom can have better lateral deflection adaptability during assembly, so that the overall structure can fit more closely with the power strip shell.

[0037] In this embodiment, the top end face of the copper core and the side end faces on the front and rear sides have rounded corners, which makes the corner structure more rounded and smooth, can reduce the residual burrs, and is also beneficial to prevent scratches on the operator's hands or other connecting cable components during the production process.

[0038] Combination Figure 4 In actual assembly, two copper cores can be symmetrically arranged horizontally and installed inside the shell of the power strip, and two insertion gaps 4 on the same side of the two copper cores in the left and right directions are used to form a combination structure corresponding to the power strip sockets, such as Figure 4 In other embodiments, a plurality of plug-in portions 2 arranged side by side may be arranged on the left and right sides of the base portion 1, or the plurality of plug-in portions 2 and the base portion 1 may be arranged in an alternating manner.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
