Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary tools for assembling adapter plugs, and in particular to a terminal guide structure for adapter plugs. Background Technology
[0002] Power adapter plugs are a type of power conversion device, mainly used in key connection nodes such as control boxes, distribution boxes, and industrial equipment that require power distribution and signal transmission. Power adapter plugs need to be compatible with single-phase and three-phase power supplies, as well as adapt to signal conversion functions, therefore they need to have multiple power pins and multiple signal pins.
[0003] Reference Figure 1 As shown, the existing power adapter plug includes a plug body 1 and a pin assembly 2. The pin assembly 2 is composed of multiple power pins 21 and multiple signal pins 21. During assembly, the pin assembly 2 needs to be inserted into the plug body 1 and the pins 21 need to be inserted into the sockets in the plug body 1 to complete the assembly.
[0004] However, during the actual assembly process, when the pin assembly is inserted into the plug body, the human eye cannot observe the assembly status of the socket and pins inside the plug body. The assembly is mismatched, so the staff needs to slowly rotate and calibrate it, which makes the assembly difficult and inefficient. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a terminal guide structure for an adapter plug to solve the technical problems of difficult assembly and low assembly efficiency in the prior art.
[0006] This utility model provides a terminal guide structure for an adapter plug, including:
[0007] Mounting base;
[0008] Multiple guide members are provided, all of which are located on one side of the mounting base, and each of the multiple guide members corresponds to a pin of the pin assembly.
[0009] During assembly, the plurality of guides extend into the plug body and pass through the plurality of sockets within the plug body until they come into contact with the pins of the pin assembly.
[0010] Optionally, the guide includes a guide post, one end of which is connected to the mounting base, and the other end extends toward the plug body.
[0011] Optionally, a flexible layer is provided on the outer wall of the guide post, and when the guide post passes through the socket inside the plug body, the flexible layer abuts against the socket wall.
[0012] Optionally, the end of the guide post facing away from the mounting base is configured as an arc shape.
[0013] Optionally, the guide post is detachably connected to the mounting base.
[0014] Optionally, the mounting base is provided with multiple slots, and the guide post is engaged into the corresponding slot.
[0015] Optionally, an elastic layer is provided between the guide post and the inner wall of the slot, so that when the guide post is inserted into the slot, the elastic layer abuts against both the inner wall of the slot and the guide post.
[0016] Optionally, a magnet is provided on the end of the guide post facing away from the mounting base. When the guide post approaches the pin assembly, the magnet can attract the pins of the pin assembly.
[0017] Optionally, a fixing member is provided on the side of the mounting base facing away from the guide member, and the mounting base is detachably connected to the worktable through the fixing member.
[0018] Optionally, the fastener may be a magnet or an adhesive layer.
[0019] The technical solution of this utility model has the following advantages:
[0020] 1. The adapter plug terminal guide structure provided by this utility model, through the cooperation of the mounting base and the guide, allows the guide to be accurately inserted into the plug body before the pin assembly is assembled into the plug body, and ensures that each guide can pass through the corresponding socket. At this time, it is only necessary to align and abut the ends of each pin of the pin assembly with the corresponding guide to achieve guidance. Then, the pin assembly is moved into the plug body simultaneously until each pin of the pin assembly is assembled into the socket. The assembly is convenient, and all pins can be assembled into the plug body at one time without the need for workers to slowly rotate and align them, resulting in high assembly efficiency.
[0021] 2. The adapter plug terminal guide structure provided by this utility model has a flexible layer on the outer wall of the guide post, so that when the guide post is inserted into the socket, it makes flexible contact with the socket, preventing direct hard contact and friction between the socket and the guide post, and effectively protecting the internal structure of the plug body.

[0038] Example
[0039] Reference Figures 2-8 As shown, this utility model provides a terminal guide structure for an adapter plug, including a mounting base 3 and guide members 4. The mounting base 3 is configured as a frustum, and multiple guide members 4 are provided and are all disposed on one side of the mounting base 3. The multiple guide members 4 are arranged in parallel and are configured as straight columns. The number of guide members 4 is consistent with the number of pins 21 of the pin assembly 2, so that the multiple guide members 4 can correspond one-to-one with the pins 21 of the pin assembly 2 and the sockets in the plug body 1. When assembled, the multiple guide members 4 all extend into the plug body 1 and pass through the multiple sockets in the plug body 1 one-to-one until they correspond to and abut against the pins 21 of the pin assembly 2.
[0040] With the cooperation of the mounting base 3 and the guide 4, before assembling the pin assembly 2 into the plug body 1, the guide 4 is precisely inserted into the plug body 1, and each guide 4 can pass through the corresponding socket. At this time, it is only necessary to align and abut the ends of each pin 21 of the pin assembly 2 with the corresponding guide 4 to achieve guidance. Then, the pin assembly 2 is moved into the plug body 1 in sync until each pin 21 of the pin assembly 2 is assembled into the socket. The assembly is convenient, and all pins 21 can be assembled into the plug body 1 at one time without the need for workers to slowly rotate and align them, resulting in high assembly efficiency.
[0041] In one specific implementation, the guide member 4 includes a guide post 41. One end of the guide post 41 is connected to one side of the mounting base 3, and the other end extends towards the plug body 1, allowing all guide posts 41 to extend into the plug body 1. The linear extension characteristic of the guide post 41 ensures that the guide post 41 can be inserted vertically into the socket along a preset path, reducing friction between the guide post 41 and the socket wall. Furthermore, the length of the guide post 41 is not uniquely limited; the guide post 41 only needs to be able to pass through the socket in the plug body 1 and facilitate connection between the operator and the pin assembly 2.
[0042] Furthermore, a flexible layer 5 is provided on the outer side wall of the guide post 41. The flexible layer 5 is annular and covers the entire outer side wall of the guide post 41. The flexible layer 5 can be made of silicone or polyurethane material. When the guide post 41 passes through the socket inside the plug body 1, the flexible layer 5 abuts against the socket wall, so that when the guide post 41 is inserted into the socket, it makes flexible contact with the socket, preventing direct hard contact and friction between the socket and the guide post 41, effectively protecting the internal structure of the plug body 1.
[0043] In addition, the end of the guide post 41 facing away from the mounting base 3 is set in an arc shape, so that when the guide post 41 is inserted into the socket, it plays a guiding role, reducing the accuracy requirement of the guide post 41 in aligning with the socket, and making it easier to insert the guide post 41 into the socket.
[0044] As one specific implementation method, refer to Figure 2 and Figure 3 As shown, the guide post 41 is detachably connected to the mounting base 3, allowing workers to quickly replace the guide post 41 at any time. When assembling different plug bodies 1, the number and model of the guide posts 41 can be configured according to the actual situation to adapt to multiple plug models, thus broadening its applicability. Furthermore, the mounting base 3 has multiple slots 6 on the side facing the guide post 41. The guide post 41 is inserted into the corresponding slot 6 and secured within it, enabling tool-free quick installation and removal, further shortening the time for replacing and installing the guide post 41.
[0045] In order to enable the guide post 41 to be locked in the slot 6, an elastic layer 7 is provided between the guide post 41 and the inner wall of the slot 6. Specifically, the elastic layer 7 is fixedly installed on the side wall of the guide post 41 facing the slot 6. The elastic layer 7 can be made of rubber. When the guide post 41 is locked in the slot 6, the elastic layer 7 is compressed, thereby pressing against the inner wall of the slot 6 and the guide post 41, so as to lock it in the slot 6.
[0046] As another implementation method, refer to Figure 3As shown, a magnet 8 is provided on the end of the guide post 41 facing away from the mounting base 3. The magnet 8 is a magnet and is fixedly installed at the end of the guide post 41. At the same time, the corner of the end of the magnet 8 facing away from the guide post 41 is rounded. When the guide post 41 approaches the pin assembly 2, the magnet 8 can attract the pin 21 of the pin assembly 2. This provides tactile feedback when the guide post 41 and the pin 21 are connected. The operator can sense whether the pin 21 has been successfully connected with the corresponding guide post 41 through the magnetic attraction. At the same time, the magnet 8 can also help to pre-fix the pin 21, so as to prevent the pin 21 from separating from the guide post 41 during the process of the pin assembly 2 moving to the socket, which would cause the guide to fail.
[0047] As another implementation method, refer to Figure 3 As shown, a fixing member 9 is provided on the side of the mounting base 3 facing away from the guide member 4. The mounting base 3 is detachably connected to the workbench through the fixing member 9 to ensure the stability of the guide structure during the assembly of the plug body 1 and the pin assembly 2, and to avoid shaking or displacement caused by manual handling. Specifically, the fixing member 9 can be set as a magnet or an adhesive layer, which is convenient for fixing and avoids the cumbersome operation of traditional bolt fixing.
[0048] Working principle: During assembly, first, the mounting base 3 is fixed to the workbench with the fastener 9 on the side facing away from the guide post 41. The operator takes out the plug body 1, with the bottom of the plug body 1 facing the guide post 41. The plug body 1 is moved towards the guide post 41 until the guide post 41 extends into the plug body 1. From the front of the plug body 1, multiple guide posts 41 are passed through the sockets one by one until the plug body 1 and the side wall of the mounting base 3 are in contact. Then, the pin assembly 2 is taken out and moved towards the guide post 41 so that multiple pins 21 of the pin assembly 2 correspond to the end of the guide post 41 facing away from the mounting base 3 until the pins 21 of the pin assembly 2 are attracted and connected to the magnet 8 on the top of the guide post 41. Then, the plug body 1 is moved upward so that the socket on the plug body 1 moves from the guide post 41 to the pin 21, thereby realizing the assembly of the pin assembly 2 and the plug body 1. After the assembly is completed, the plug body 1 can be removed from the adapter plug terminal guide structure. The assembly is convenient, quick and efficient.
[0049] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
