Description

Technical Field

[0001] This utility model relates to the field of pin header plug technology, and in particular to a protective pin header plug. Background Technology

[0002] Pin header connectors are widely used on PCBs, typically to establish circuit connections between the PCB and the load. Existing pin header connectors consist of several connector units, each including a housing and pins. The pins extend from both ends of the housing, forming an upper pin section and a lower pin section. The lower pin section is used to connect to the PCB, and the upper pin section is used to connect to the load, thus achieving the connection between the load and the PCB.

[0003] In the current use of pin headers, the pin headers at both ends are connected to the host and the monitor respectively. However, when not connected, the pin headers are prone to bending due to external force because of their length, flexibility, and small diameter, which prevents the pin header from connecting to external devices. Utility Model Content

[0004] The main purpose of this invention is to provide a protective pin header plug.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A protective pin header connector includes a plug, a limiting mechanism installed on one side of the plug, a pin header fixed in the middle of the plug, and a protective component disposed on the plug outside the pin header. The protective component includes a slot formed on the plug, a plurality of return springs distributed in a rectangular shape in the slot, a protective plate fixed to one end of the return spring, and the pin header passing through the protective plate. The protective plate has a through hole for receiving the pin header.

[0007] Preferably, the limiting mechanism includes a limiting plate and a limiting frame, and the limiting plate is fixed to the plug.

[0008] Preferably, the limiting frame is fixed to the limiting plate, and the limiting frame has a trapezoidal structure and is located outside the protective plate.

[0009] Preferably, a connector is installed on the other side of the plug, and the connector contains wires that are electrically connected to the pin header.

[0010] Preferably, a fastening mechanism is symmetrically arranged on the side of the plug away from the limiting mechanism. The fastening mechanism includes a support sleeve, a fastening rod, a threaded groove, a rotating head, friction patterns, and a baffle.

[0011] Preferably, the support sleeve is fixed to the plug, and the fastening rod is slidably connected to the support sleeve, with the fastening rod passing through the plug and the protective plate.

[0012] Preferably, one end of the fastening rod is formed with a threaded groove, and the other end of the fastening rod is fixed with a rotating head, the rotating head being formed with friction patterns.

[0013] Preferably, a limiting plate is installed on the fastening rod, and the diameter of the limiting plate is smaller than the inner diameter of the support sleeve.

[0014] The beneficial effects of this technology are:

[0015] By incorporating a protective component, when not in use, the protective plate moves to the outside of one end of the pin header via a return spring within the slot. This reduces the exposed length of the pin header, preventing it from bending under external force and ensuring easy connection of the plug to external devices. During use, the protective plate compresses the return spring and moves into the slot, thus fulfilling the plug's connection requirements. Attached Figure Description

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-3As shown, this embodiment provides a protective pin header plug, including a plug 1, a limiting mechanism 2 installed on one side of the plug 1, a pin header 3 fixed in the middle of the plug 1, and a protective component 4 provided on the plug 1 outside the pin header 3. The protective component 4 includes a slot 401 opened on the plug 1, the slot 401 is used to carry a return spring 402, and multiple sets of return springs 402 are rectangularly distributed in the slot 401. The return spring 402 can move the protective plate 403 to the outside of one end of the pin header 3. The protective plate 403 is fixed to one end of the return spring 402. The protective plate 403 can reduce the exposed length of the pin header 3, and the pin header 3 passes through the protective plate 403. The protective plate 403 has a through hole for carrying the pin header 3.

[0023] like Figures 1-2 As shown, the limiting mechanism 2 includes a limiting plate 201 and a limiting frame 202, and the limiting plate 201 is fixed on the plug 1, so that the limiting frame 202 can be connected and fixed to the plug 1 through the limiting plate 201.

[0024] like Figures 1-2 As shown, the limiting frame 202 is fixed on the limiting plate 201, and the limiting frame 202 has a trapezoidal structure. The limiting frame 202 is located outside the protective plate 403 and can limit the connection of the plug 1 to the external equipment.

[0025] like Figures 1-2 As shown, a connector 5 is installed on the other side of the plug 1, and the connector 5 contains wires that are electrically connected to the pin header 3, so that external connecting wires can be connected to the plug 1 through the connector 5.

[0026] like Figures 1-3 As shown, a fastening mechanism 6 is symmetrically arranged on the side of the plug 1 away from the limiting mechanism 2. The fastening mechanism 6 includes a support sleeve 601, a fastening rod 602, a threaded groove 603, a rotating head 604, a friction texture 605, and a baffle 606, which facilitates the connection and fixation of the plug 1 to external equipment through the fastening mechanism 6.

[0027] like Figures 1-3 As shown, the support sleeve 601 is fixed on the plug 1, and the fastening rod 602 is slidably connected to the support sleeve 601. The fastening rod 602 passes through the plug 1 and the protective plate 403, which facilitates the movement of the fastening rod 602 within the support sleeve 601.

[0028] like Figures 1-3 As shown, one end of the fastening rod 602 is formed with a threaded groove 603, and the other end of the fastening rod 602 is fixed with a rotating head 604. The rotating head 604 is formed with friction textures 605, which makes it convenient for the operator to use the rotating head 604 to drive the fastening rod 602 to rotate. During the rotation of the fastening rod 602, it is connected to the external equipment through the threaded groove 603, and the friction textures 605 increase the friction between the rotating head 604 and the operator's hand during use.

[0029] like Figures 1-3 As shown, a limiting plate 201 is installed on the fastening rod 602, and the diameter of the limiting plate 201 is smaller than the inner diameter of the support sleeve 601, which can prevent the fastening rod 602 from detaching from the support sleeve 601 through the baffle 606.

[0030] The working principle of this device is as follows: When in use, the external connection line is connected to the plug 1 through the connector 5. When the plug 1 is not in use, the protective plate 403 moves to the outside of one end of the pin 3 through the return spring 402 in the slot 401. The protective plate 403 reduces the exposed length of the pin 3, thereby preventing the pin 3 from bending due to external force and ensuring that the plug 1 can be easily connected to the external device. When the plug 1 is connected to the external device, the operator aligns the limit bracket 202 with the connection point of the external device and inserts it, and connects the pin 3 to the circuit inside the device. During the insertion process, the protective plate 403 is compressed by the force of the return spring 402 and moves into the slot 401, thereby meeting the connection requirements of the plug 1. After the insertion is completed, the operator uses the rotating head 604 to drive the fastening rod 602 to rotate. During the rotation of the fastening rod 602, it is connected to the external device through the threaded groove 603. In addition, during use, the friction groove 605 increases the friction between the rotating head 604 and the operator's hand.

[0031] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
