Description

Technical Field

[0001] This utility model relates to the field of electrical terminal technology, and in particular to a bent plug structure with an anti-disengagement latch. Background Technology

[0002] Bent plugs are common electrical connection components within the category of electrical terminals. Their main body is mostly made of conductive materials such as copper alloys, and the surface is often tin-plated or gold-plated to prevent oxidation and reduce contact resistance. They are named for their "bent" shape. Their core function is to enable detachable electrical conduction between two components in a circuit. The bent design can adapt to compact or irregularly shaped installation spaces inside equipment, avoiding the excessive vertical space occupied by straight plugs. Therefore, a bent plug structure with an anti-disengagement latch is particularly needed.

[0003] However, the existing bent plug-in connectors often rely on welding to connect with corresponding components. This process is not only cumbersome and requires a certain level of precision, but also may affect the electrical conductivity stability due to uneven welding quality. More importantly, if the plug-in or related components need to be repaired or replaced later, the welding method will greatly increase the difficulty of disassembly. This is not only time-consuming and labor-intensive, but may also cause accidental damage to surrounding circuits or components during disassembly. Overall compatibility and ease of maintenance need to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a bent insert structure with an anti-detachment locking buckle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bent insert structure with an anti-detachment latch, comprising a PCB board and positioning holes, wherein a relay is fixedly connected to one side surface of the PCB board, a connector is fixedly connected to one side surface of the PCB board, a capacitor is fixedly connected to one side surface of the PCB board, a chip is fixedly connected to one side surface of the PCB board, and an anti-detachment mechanism is provided on one side surface of the PCB board. The anti-detachment mechanism includes a fixing base, which is fixedly connected to one side surface of the PCB board.

A pin is inserted into the inner side of the slot, and an insulator is fixedly connected to the outer side of the pin. A protrusion is slidably connected to the inner side of the sliding groove. A sliding cover is fixedly connected to one side surface of the protrusion. Anti-slip stripes are fixedly connected to one side surface of the sliding cover. An insert is fixedly connected to one side surface of the sliding cover, and a fixing block is fixedly connected to one side surface of the insert.

[0006] Preferably, the pins and the insulator are provided with multiple pins of the same size, the cross-section of the pins is designed in an "L" shape, and the size of the insulator is adapted to the rectangular slot.

[0007] Preferably, the anti-slip stripes are provided in multiple sizes and are arranged at equal intervals along the horizontal and vertical central axis of the sliding cover.

[0008] Preferably, the card slot and rectangular slot are provided in multiple sizes and are arranged at equal distances along the horizontal central axis of the fixing base, and the pins are adapted to the size of the card slot.

[0009] Preferably, the protrusions are provided in two identical sizes and are symmetrically distributed along the horizontal central axis of the sliding cover, and the slide grooves are provided in two identical sizes and are symmetrically distributed along the horizontal central axis of the fixing seat, and the sizes of the protrusions and slide grooves are adapted to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This bent insert structure with anti-detachment latch can quickly complete the initial positioning of the insert due to the size matching between the pin and the slot, and between the insulator and the rectangular slot. It can achieve the pre-connection of the pin and the PCB board without welding, avoiding the problems of cumbersome traditional welding operations and high process precision requirements. It also avoids the hidden dangers of poor soldering and missing soldering that may affect the conductivity stability during the welding process, which greatly reduces the installation threshold and time cost. The sliding cover indirectly presses the pin and the insulator through the cooperation of the insert block and the connection hole. This double-limit mechanical locking design can effectively resist the risk of detachment in scenarios such as equipment vibration and external force collision compared with the traditional structure without anti-detachment, and significantly improves the stability and reliability of electrical connection.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a bent insert structure with anti-detachment latch, including a PCB board 1 and a positioning hole 2. A relay 3 is fixedly connected to one side surface of the PCB board 1, a connector 4 is fixedly connected to one side surface of the PCB board 1, a capacitor 5 is fixedly connected to one side surface of the PCB board 1, a chip 6 is fixedly connected to one side surface of the PCB board 1, and an anti-detachment mechanism 7 is provided on one side surface of the PCB board 1. The anti-detachment mechanism 7 includes a fixing base 701, which is fixedly connected to one side surface of the PCB board 1. A slot 702, a rectangular groove 703, a sliding groove 704, a connecting hole 705, and a fixing groove 706 are formed on one side surface of the fixing base 701. A pin 707 is inserted into the inner side of the slot 702, and an insulator 708 is fixedly connected to the outer side of the pin 707. A protrusion 709 is slidably connected to the inner side of the sliding groove 704. A sliding cover 710 is fixedly connected to one side surface of the protrusion 709, and an anti-detachment device is fixedly connected to one side surface of the sliding cover 710. The sliding cover 710 has a sliding stripe 711, and a sliding block 712 is fixedly connected to one side surface of the sliding cover 710. A fixing block 713 is fixedly connected to one side surface of the sliding block 712. Through the arrangement of the fixing seat 701, the slot 702, the rectangular groove 703, the sliding groove 704, the connecting hole 705, the fixing groove 706, the pin 707, the insulator 708, the protrusion 709, the sliding cover 710, the anti-slip stripe 711, the sliding block 712, and the fixing block 713, in use, the insert is first pre-positioned. The "L"-shaped pin 707 with the insulator 708 is aligned with the slot 702 of the fixing seat 701, and at the same time, the insulator 708 is embedded in the corresponding rectangular groove 703. Because the pin 707 and the slot 702, the insulator 708 and the rectangular groove are aligned, the pin 707 and the slot 702, the insulator 708 and the rectangular groove are aligned. The size of 703 allows for quick initial positioning of the insert, enabling pre-connection of pin 707 to PCB 1 without soldering, thus solving the problem of cumbersome traditional soldering. Next, the sliding cover 710 is pushed and locked. The operator holds the anti-slip stripes 711 on the surface of the sliding cover 710, which are evenly spaced along the central axis to increase hand friction and facilitate force application. The operator pushes the sliding cover 710 along the groove 704 of the fixing base 701. At this time, the protrusions 709 on both sides of the sliding cover 710 slide stably along the groove 704, causing the insert 712 below the sliding cover 710 to embed into the connection hole 705 of the fixing base 701. As the sliding cover 710 continues to advance, the "⊿"-shaped fixing block 713 at the end of the insert 712 will precisely engage with the fixing base 701. In the fixing slot 706 of 01, the fixing block 713 and the fixing slot 706 are matched in size to form a mechanical locking structure, which ultimately achieves the anti-disengagement effect. After locking, the "⊿" shaped fixing block 713 restricts the reverse movement of the sliding cover 710 through the fixing slot 706. The sliding cover 710 indirectly presses the pin 707 and the insulator 708 through the cooperation of the insert block 712 and the connecting hole 705, so as to prevent the pin 707 from accidentally coming out of the slot 702. The entire disassembly process does not require disassembling the solder joints. It is not only simple to operate and short in time, but also avoids the accidental damage to the PCB board 1 and surrounding components such as relay 3, connector 4, capacitor 5, and chip 6 caused by traditional soldering and disassembly, which greatly improves the convenience of later maintenance and component replacement.

[0017] Furthermore, multiple pins 707 and insulators 708 of the same size are provided. The cross-section of pin 707 is designed in an "L" shape. The size of insulator 708 is adapted to that of rectangular slot 703. Through the arrangement of insulator 708 and rectangular slot 703, in use, rectangular slot 703 can provide lateral limit for insulator 708 by matching the size of insulator 708, so as to prevent insulator 708 from shifting left or right.

[0018] Furthermore, the anti-slip stripes 711 are provided in multiples of the same size and are arranged at equal intervals along the horizontal and vertical central axis of the sliding cover 710. With the provision of anti-slip stripes 711, the equally spaced anti-slip stripes 711 of the same size can form a uniform and stable friction force during use, compared with a stripeless design, which greatly reduces the rate of operational errors.

[0019] Furthermore, the card slot 702 and rectangular slot 703 are provided with multiple slots of the same size, and are arranged at equal intervals along the horizontal and vertical central axis of the fixing base 701. The pins 707 are adapted to the size of the card slot 702. Through the arrangement of the pins 707 and the card slot 702, the size compatibility between the pins 707 and the card slot 702 replaces the traditional fixing effect of soldering on the position of the pins 707 during use. This not only achieves convenient installation without soldering, but also ensures conductive contact area through physical bonding, reduces contact resistance, and improves the stability of current transmission.

[0020] Furthermore, two protrusions 709 of the same size are provided and are symmetrically distributed along the horizontal central axis of the sliding cover 710. Two slide grooves 704 of the same size are provided and are symmetrically distributed along the horizontal central axis of the fixing base 701. The sizes of the protrusions 709 and the slide grooves 704 are adapted to each other. With the provision of protrusions 709 and slide grooves 704, the protrusions 709 can slide smoothly along the inner wall of the slide grooves 704 during use. The double-set symmetrical distribution design allows the sliding guide force on the sliding cover 710 to be evenly applied to both sides of the central axis, preventing the sliding cover 710 from shifting to one side when pushed.

[0021] Furthermore, two insert blocks 712 and fixing blocks 713 of the same size are provided and are symmetrically distributed along the horizontal central axis of the sliding cover 710. The size of the insert block 712 is adapted to the size of the connecting hole 705. Through the setting of the insert block 712 and the connecting hole 705, the connecting hole 705 will provide guidance for the insert block 712 during use, ensuring that the fixing block 713 is accurately connected to the fixing groove 706.

[0022] Furthermore, the cross-section of the fixing block 713 is designed in the shape of a "⊿". The size of the fixing block 713 is adapted to the fixing groove 706. With the setting of the fixing block 713 and the fixing groove 706, when the fixing block 713 contacts the edge of the fixing groove 706 during use, no deliberate calibration is required. The inclined surface can guide the fixing block 713 to slide smoothly into the groove. At the same time, because the two are adapted to each other, the fixing block 713 can be completely locked into the fixing groove 706 to form a tight mechanical engagement.

[0023] Working principle: During installation and anti-detachment locking, the insert is first pre-positioned. The "L"-shaped pin 707 with insulator 708 is aligned with the slot 702 of the fixing base 701, while the insulator 708 is embedded in the corresponding rectangular slot 703. Because the pin 707 and slot 702, and the insulator 708 and rectangular slot 703 are sized to match, the initial positioning of the insert can be quickly completed. Pre-connection of pin 707 to PCB board 1 can be achieved without soldering, solving the problem of cumbersome traditional soldering. Then, the sliding cover 710 is... Pushing the locking mechanism, the operator holds the anti-slip stripes 711 on the surface of the sliding cover 710, which are equidistant along the central axis to increase hand friction and facilitate force application. The operator pushes the sliding cover 710 along the slide groove 704 of the fixing base 701. At this time, the protrusions 709 on both sides of the sliding cover 710 slide stably along the slide groove 704, causing the insert block 712 below the sliding cover 710 to embed into the connecting hole 705 of the fixing base 701. As the sliding cover 710 continues to advance, the "⊿"-shaped fixing block 713 at the end of the insert block 712 will precisely engage with the fixing base 701. In the fixed slot 706, because the fixed block 713 and the fixed slot 706 are sized to match, a mechanical locking structure is formed, ultimately achieving an anti-disengagement effect. After locking, the "⊿"-shaped fixed block 713 restricts the reverse movement of the sliding cover 710 through the fixed slot 706. The sliding cover 710 indirectly presses the pin 707 and the insulator 708 through the cooperation of the insert block 712 and the connecting hole 705, preventing the pin 707 from accidentally disengaging from the slot 702. At the same time, multiple slots 702 and rectangular slots 703 are equidistantly arranged along the central axis of the fixed base 701, which can... The simultaneous locking of multiple sets of pins 707 further enhances the stability of the overall connection. When it is necessary to replace the insert, simply use the connection hole 705 to move the "⊿" shaped fixing block 713 to disengage it from the fixing groove 706, and then let the protrusion 709 return to the initial position along the slide groove 704. At this time, the locking of the fixing seat 701 on the pin 707 is released, and the pin 707 and the insulator 708 can be directly pulled out from the slot 702 and the rectangular groove 703. This completes the use process of a bent insert structure with anti-disengagement latch.
