Description

Technical Field

[0001] This application relates to the field of electrical connection devices, and more specifically, to a rear-mounted panel power connector. Background Technology

[0002] In the field of power connectors, such as power strips, a common design approach to simplify production processes and improve component versatility is to use a standardized main housing structure, adapting to different specifications by replacing specific panels, and ultimately combining the differentiated panels with the main housing structure to form a complete product. However, this design suffers from the following problems in practical implementation:

[0003] The contradiction between assembly structure and space constraints: To meet the trend of product miniaturization and lightweighting, the mating structure between differentiated panels and the main shell structure is usually designed to be extremely compact, resulting in small assembly tolerances and insufficient operating space. Differentiated panels need to be installed separately after the main shell structure is formed, but the narrow mating area can easily lead to assembly difficulties or positioning deviations.

[0004] The contradiction between connection strength and mechanical reliability: Existing solutions mostly rely on simple snap-fit ​​or plug-in structures to fix differentiated panels. Although this facilitates rapid assembly, in mechanical impact tests, such as drop tests, the connection parts are prone to loosening or damage due to stress concentration, making it difficult to meet the structural strength requirements of high-reliability products. Utility Model Content

[0005] The purpose of this application is to provide a rear-mounted panel power connector to alleviate the technical problem of weak stability of differential panel connections in existing power connectors.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] The rear-mounted panel power connector provided by this utility model includes a main structural component, a panel structural component, and a retaining spring structural component.

[0008] The main structural component has a mounting cavity, and the side wall of the main structural component is provided with a mounting hole communicating with the mounting cavity. Limiting components are installed in the mounting cavity on both sides of the mounting hole.

[0009] The panel structure includes a mounting cylinder, and the outer wall of the mounting cylinder is provided with a limiting protrusion. The mounting cylinder extends into the mounting hole, and the limiting protrusion abuts against the outer wall of the main structure.

[0010] The retaining spring structure is installed between the mounting cylinder and the limiting member. The retaining spring structure includes a first limiting part and a second limiting part. One side of the first limiting part abuts against the limiting member and the other side is engaged with the mounting cylinder. One side of the second limiting part abuts against the limiting member and the other side abuts against the outer wall of the mounting cylinder. The second limiting part is elastic.

[0011] Furthermore, the second limiting part is located on the side of the first limiting part that is away from the inner wall of the main structural member.

[0012] Furthermore, the outer wall of the mounting cylinder is provided with a slot, and the first limiting part is inserted into the slot;

[0013] Alternatively, the outer wall of the mounting cylinder is provided with a protruding structure, and the first limiting part is inserted between the protruding structure and the inner wall of the main structural member.

[0014] Furthermore, the second limiting part includes an elastic segment and a fixed segment, with the fixed segment connected to both ends of the elastic segment at an included angle, and the two fixed segments located on the same side of the elastic segment;

[0015] The fixed section abuts against the limiting member, and the elastic section is elastic and abuts against the outer wall of the mounting cylinder.

[0016] Furthermore, the elastic segment includes a bending segment and an abutting segment, with the two ends of the abutting segment respectively connected to the bending segment at an included angle, and the two bending segments located on the same side of the abutting segment; the end of the bending segment away from the abutting segment is connected to the fixed segment;

[0017] The abutting section is in contact with the outer wall of the mounting cylinder.

[0018] Furthermore, the fixed segment is connected to the first limiting portion, and there is a gap between the elastic segment and the first limiting portion.

[0019] Furthermore, the outer wall of the main structural component is provided with a groove, and the mounting hole penetrates the bottom wall of the groove;

[0020] The mounting cylinder extends into the mounting hole, and the limiting protrusion fits against the bottom wall of the groove.

[0021] Furthermore, the limiting member is configured as a limiting rib that protrudes from the inner wall of the main structural member toward the center of the mounting cavity.

[0022] Furthermore, the main structural member has at least two mounting holes on the same side wall, and the mounting holes are spaced apart.

[0023] The panel structure is provided in multiple ways, and the mounting cylinders in the multiple panel structure are installed one-to-one with the multiple mounting holes.

[0024] Furthermore, two adjacent mounting holes share a single limiting member.

[0025] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows:

[0026] The rear-mounted panel power connector provided by this utility model includes a main structural component, a panel structural component, and a retaining spring structural component. The main structural component has a mounting cavity, and the side wall of the main structural component is provided with a mounting hole communicating with the mounting cavity. Limiting components are installed on both sides of the mounting hole in the mounting cavity. The panel structural component includes a mounting cylinder, and the outer wall of the mounting cylinder is provided with a limiting protrusion. The mounting cylinder extends into the mounting hole, and the limiting protrusion abuts against the outer wall of the main structural component. A retaining spring structural component is installed between the mounting cylinder and the limiting component. The retaining spring structural component includes a first limiting part and a second limiting part. One side of the first limiting part abuts against the limiting component, and the other side is engaged with the mounting cylinder. One side of the second limiting part abuts against the limiting component, and the other side abuts against the outer wall of the mounting cylinder. The second limiting part is elastic.

[0027] After the main structure of this rear-mounted panel power connector is assembled, the panel structure is installed onto the main structure, and the panel structure is fixed onto the main structure using a snap ring structure, thus realizing the rear-mounting of the panel structure and enabling multiple panel structures to share a single main structure.

[0028] When assembling the panel structure, firstly, the mounting cylinder of the panel structure is inserted into the mounting cavity through the mounting hole of the main structure, with the limiting protrusion on the mounting cylinder abutting against the outer wall of the main structure to restrict the movement of the panel structure in the direction of insertion into the mounting cavity; then, the snap ring structure is inserted between the limiting member and the mounting cylinder of the panel structure; wherein, one side of the first limiting part of the snap ring structure abuts against the limiting member, and the other side engages with the mounting cylinder, and both sides of the mounting cylinder engage with two first limiting parts respectively, and the two first limiting parts abut against two limiting members respectively, with the limiting members engaging the first limiting parts. The first limiting part is positioned to prevent movement. Two first limiting parts work together to restrict the movement of the mounting cylinder away from the mounting cavity and to its movement towards or away from the limiting member. The second limiting part of the snap ring structure abuts against the limiting member on one side and against the outer wall of the mounting cylinder on the other side, and is elastic. When the second limiting part is between the limiting member and the mounting cylinder, it is compressed, causing the second limiting part to fit tightly against the side wall of the mounting cylinder, increasing the friction between them. The second limiting part restricts the radial movement and circumferential rotation of the mounting cylinder. At this point, the panel structure is fixed, and the degrees of freedom in all directions are restricted.

[0029] When disassembling the panel structure, first pull the snap ring structure out from between the mounting cylinder and the limiting component, and then remove the panel structure from the main structure.

[0030] This rear-mounted panel power connector achieves a secure fixation of all structural components within a compact space, ensuring stable fixation without external force and improving the quality of the rear-mounted panel power connector. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] In the consumer market, product categories with high brand recognition, such as power strips, often use a unified design and are compatible with global market specifications. To save costs, they typically share a common outer shell structure, only partially replacing the panels for different markets, embedding them into a single unit. This practice is common in many industries. This approach inevitably leads to questions about the order of installation of the differentiated panels. However, the trend towards compact and refined designs in consumer products necessitates tight dimensions in the design of embedded assembly structures. Furthermore, drop tests are a mandatory requirement for reliability testing of consumer products. Conventional single-clamp structures are insufficient to guarantee the achievement of corresponding quality standards in categories with high specifications.

[0048] In view of this, the rear-mounted panel power connector provided in this embodiment of the present invention includes a main body structure 100, a panel structure 200, and a retaining spring structure 300; the main body structure 100 has a mounting cavity, and the side wall of the main body structure 100 is provided with a mounting hole 110 communicating with the mounting cavity, and a limiting member 120 is installed in the mounting cavity on both sides of the mounting hole 110; the panel structure 200 includes a mounting cylinder 210, and the outer wall of the mounting cylinder 210 is provided with a limiting protrusion 220, the mounting cylinder 210 extending into the mounting cavity... Inside the mounting hole 110, the limiting protrusion 220 abuts against the outer wall of the main structural member 100; a retaining spring structure 300 is installed between the mounting cylinder 210 and the limiting member 120. The retaining spring structure 300 includes a first limiting part 310 and a second limiting part 320. One side of the first limiting part 310 abuts against the limiting member 120, and the other side is engaged with the mounting cylinder 210; one side of the second limiting part 320 abuts against the limiting member 120, and the other side abuts against the outer wall of the mounting cylinder 210, and the second limiting part 320 is elastic.

[0049] Specifically, the main structural component 100 can be configured as either a barrel type or a planar type, without limitation; for example Figure 1 This is a schematic diagram showing the main structural component 100 as a barrel shape. Figure 7 The main structural component 100 is shown in a planar structural diagram.

[0050] After the main structure 100 of the panel rear-mounted power connector is assembled, the panel structure 200 is installed on the main structure 100, and the panel structure 200 is fixed on the main structure 100 by the snap ring structure 300, so as to realize the rear-mounting of the panel structure 200 and thus realize that multiple panel structures 200 share the same main structure 100.

[0051] When assembling the panel structure 200, firstly, the mounting cylinder 210 of the panel structure 200 is inserted into the mounting cavity through the mounting hole 110 of the main structure 100, and the limiting protrusion 220 on the mounting cylinder 210 abuts against the outer wall of the main structure 100 to restrict the movement of the panel structure in the direction of insertion into the mounting cavity; then, the snap ring structure 300 is inserted between the limiting member 120 and the mounting cylinder 210 of the panel structure; wherein, one side of the first limiting part 310 of the snap ring structure 300 abuts against the limiting member 120, and the other side is engaged with the mounting cylinder 210, and both sides of the mounting cylinder 210 are engaged with the two first limiting parts 310 respectively, and the two first limiting parts 310 abut against the two limiting members 120 respectively, and the limiting members 120 limit the first limiting part. The first limiting part 310 is positioned to prevent movement of the first limiting part 310. The two first limiting parts 310 work together to restrict the movement of the mounting cylinder 210 in the direction of disengaging from the mounting cavity, and to restrict the movement of the mounting cylinder 210 in the direction of approaching or moving away from the limiting member 120. The second limiting part 320 of the snap ring structure 300 abuts against the limiting member 120 on one side and against the outer wall of the mounting cylinder 210 on the other side, and is elastic. When the second limiting part 320 is located between the limiting member 120 and the mounting cylinder 210, it is compressed, causing the second limiting part 320 to fit tightly against the side wall of the mounting cylinder 210, increasing the friction between them. The second limiting part 320 restricts the movement of the mounting cylinder 210 in its radial direction and restricts the rotation of the mounting cylinder 210 in its circumferential direction. At this time, the panel structure 200 has been fixed, and the degrees of freedom in all directions have been restricted.

[0052] When disassembling the panel structure 200, first pull the snap ring structure 300 out from between the mounting cylinder 210 and the limiting member 120, and then remove the panel structure 200 from the main structure 100.

[0053] This rear-mounted panel power connector features a pin-type snap-fit ​​structure that, when engaged, securely fixes all structural components within a compact space, ensuring a stable fixation that prevents detachment under non-forced external conditions and thus improving the quality of the rear-mounted panel power connector.

[0054] The following is a detailed description of the structure of the rear-mounted panel power connector:

[0055] In the optional solution provided by this utility model embodiment, the second limiting part 320 is located on the side of the first limiting part 310 away from the inner wall of the main structural member 100.

[0056] Specifically, see Figure 1 The second limiting part 320 is located above the first limiting part 310, and the cross-section of the first limiting part 310 and the second limiting part 320 as a whole is L-shaped, which makes the structure of the snap ring structure 300 stable.

[0057] In the optional solution provided by this utility model embodiment, the outer wall of the mounting cylinder 210 is provided with a slot 211, and the first limiting part 310 is inserted into the slot 211.

[0058] Specifically, see Figure 3 The outer wall of the mounting cylinder 210 is provided with a slot 211 extending circumferentially, and the first limiting part 310 is inserted into the slot 211 to achieve the engagement of the first limiting part 310 with the mounting cylinder 210. Furthermore, the outer wall of the mounting cylinder 210 is provided with two slots 211, and the two slots 211 are symmetrically arranged.

[0059] The mounting cylinder 210 and the first limiting part 310 are engaged by the slot 211, which is simple in structure and easy to manufacture.

[0060] In another embodiment, the outer wall of the mounting cylinder 210 is provided with a protruding structure, and the first limiting part 310 is inserted between the protruding structure and the inner wall of the main structural member 100.

[0061] Specifically, the protruding structure extends outward from the outer wall of the mounting cylinder 210, and the protruding structure and the limiting structure are spaced apart along the axial direction of the mounting cylinder 210; there are two protruding structures, which are symmetrically arranged; or, the protruding structure extends in a circle along the circumference of the mounting cylinder 210. It is worth noting that the maximum outer diameter of the protruding structure is less than or equal to the diameter of the mounting hole 110, and the maximum outer diameter of the limiting protrusion 220 is greater than the diameter of the mounting hole 110.

[0062] When the mounting cylinder 210 extends into the main structural member 100, there is a gap between the protruding structure and the inner wall of the main structural member 100. The first limiting part 310 is inserted into the gap to achieve a snap-fit ​​with the mounting cylinder 210, and the protruding structure can improve the strength of the mounting cylinder 210.

[0063] In the optional solution provided by this utility model embodiment, the second limiting part 320 includes an elastic segment 321 and a fixed segment 322. The two ends of the elastic segment 321 are connected to the fixed segment 322 at an included angle, and the two fixed segments 322 are located on the same side of the elastic segment 321. The fixed segment 322 abuts against the limiting member 120, and the elastic segment 321 is elastic and abuts against the outer wall of the mounting cylinder 210.

[0064] Specifically, see Figure 2 and Figure 8 Both ends of the elastic segment 321 are connected to the fixed segment 322 at an included angle, so that the elastic segment 321 can move elastically relative to the fixed segment 322, and the elastic segment 321 does not abut against the limiting member 120, thus avoiding the problem that the elastic segment 321 cannot move elastically.

[0065] The fixed section 322 is used to abut against the limiting member 120, and the elastic section 321 is used to abut against the outer wall of the mounting cylinder 210.

[0066] In the optional embodiment of this utility model, the elastic segment 321 includes a bending segment 3211 and an abutting segment 3212. The two ends of the abutting segment 3212 are respectively connected to the bending segment 3211 at an included angle, and the two bending segments 3211 are located on the same side of the abutting segment 3212. The end of the bending segment 3211 away from the abutting segment 3212 is connected to the fixing segment 322. The abutting segment 3212 is in contact with the outer wall of the mounting cylinder 210.

[0067] Specifically, the two ends of the bending section 3211 are connected at an angle to the abutting section 3212 and the fixed section 322, respectively, so that the elastic section 321 and the fixed section 322 are connected at an angle.

[0068] The abutment section 3212 increases the contact area between the elastic section 321 and the mounting cylinder 210, thereby enhancing the limiting effect on the mounting cylinder 210.

[0069] In the optional solution provided by this utility model embodiment, the fixed segment 322 is connected to the first limiting part 310, and the elastic segment 321 has a gap 330 with the first limiting part 310.

[0070] Specifically, see Figure 2 The snap ring structure 300 can be configured as a three-dimensional spatial component formed by bending a flexible sheet metal; or, see [link to relevant documentation]. Figure 8 The snap ring structure 300 can be configured as a skeleton-type spatial three-dimensional component formed by bending an elastic steel wire; or, the snap ring structure 300 can be configured as an alloy molded component with a spring sheet. Furthermore, the snap ring structure 300 forms a first limiting part 310 arranged in a slightly horizontal direction and a second limiting part 320 arranged in a slightly vertical direction in a three-dimensional space, realizing a two-way cooperating functional area; of course, the two directions are not limited to the requirement of being completely perpendicular.

[0071] The fixed segment 322 is connected to the first limiting part 310, thereby connecting the first limiting part 310 and the second limiting part 320, which facilitates the simultaneous insertion of the first limiting part 310 and the second limiting part 320 between the mounting cylinder 210 and the limiting member 120; the elastic segment 321 has a gap 330 with the first limiting part 310, which allows the elastic segment 321 to move elastically.

[0072] In the optional solutions provided by the embodiments of this utility model, see Figures 4 to 6 The outer wall of the main structural component 100 is provided with a groove 130, and the mounting hole 110 penetrates the bottom wall of the groove 130; the mounting cylinder 210 extends into the mounting hole 110, and the limiting protrusion 220 fits against the bottom wall of the groove 130.

[0073] Specifically, the height of the limiting protrusion 220 is consistent with the depth of the groove 130, so that the surface of the panel structure 200 is flush with the outer wall of the main structure 100 after installation, avoiding the problem that the protrusion of the panel structure 200 is easily damaged by impact. Furthermore, the mounting cylinder 210 is cylindrical, the groove 130 is circular, and the outer wall of the limiting protrusion 220 fits against the inner wall of the groove 130.

[0074] The groove 130 is used to accommodate the limiting protrusion 220, so that the surface of the panel structure 200 is flush with the outer wall of the main structure 100 after installation.

[0075] In the optional solution provided by this utility model embodiment, the limiting member 120 is configured as a limiting rib that protrudes from the inner wall of the main structural member 100 toward the center of the mounting cavity.

[0076] Specifically, see Figure 4 The limiting rib is integrally formed with the main structural component 100, for example, by injection molding using a mold to form the main structural component 100 with the limiting rib.

[0077] The limiting component 120 is set as a limiting rib integrally formed with the main structural component 100, which improves the connection strength and the installation accuracy of the limiting rib.

[0078] In the optional solution provided by the embodiment of this utility model, the main structural component 100 has at least two mounting holes 110 on the same side wall, and the multiple mounting holes 110 are spaced apart; the panel structural component 200 is provided in multiple ways, and the mounting cylinder 210 in the multiple panel structural components 200 is installed in a one-to-one correspondence with the multiple mounting holes 110.

[0079] Specifically, see Figure 1 and Figure 7 In this embodiment, the main structural member 100 is provided with two mounting holes 110, which are spaced apart along the length of the main structural member 100. Of course, the main structural member 100 may also have one, three, or four mounting holes 110, which should also be within the protection scope of this utility model embodiment. Furthermore, the multiple panel structural members 200 can be configured as different types of panel structural members 200; or, the multiple panel structural members 200 can all be of the same type; or, the multiple panel structural members 200 can be divided into multiple groups, with the panel structural members 200 of the same type in each group and the panel structural members 200 of different types in different groups.

[0080] One or more mounting holes 110 are provided on the same side wall of the main structural component 100, so that multiple panel structural components 200 can be installed on the same main structural component 100.

[0081] In the optional solution provided by this utility model embodiment, two adjacent mounting holes 110 share a limiting member 120.

[0082] Specifically, see Figure 1 When the main structural component 100 has two mounting holes 110, only three limiting components 120 are needed; and so on. Of course, the scheme in which two adjacent mounting holes 110 are provided with two limiting components 120, that is, each of the two adjacent mounting holes 110 has a corresponding limiting component 120 independently, should also be within the protection scope of this utility model embodiment.

[0083] Two adjacent mounting holes 110 share a single limiting element 120, which reduces the number of limiting elements 120 and lowers the weight, volume, and cost of the main structural component 100.

[0084] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0085] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
