Description

Technical Field

[0001] This utility model relates to the field of security device technology, specifically a rapid connection device for low-voltage security monitoring lines. Background Technology

[0002] Low-voltage security monitoring systems utilize low-voltage technology to provide security functions such as video surveillance, intrusion alarms, and access control. These systems are widely used in public places, commercial buildings, and residential areas to enhance security capabilities and protect personal and property safety. The core of a low-voltage security monitoring system lies in the stability and reliability of its wiring, ensuring the stable operation of monitoring equipment and enabling real-time monitoring and information transmission.

[0003] In modern security monitoring systems, the connection and connection of low-voltage lines are crucial for ensuring the normal operation of the equipment. Traditional low-voltage security monitoring line connection devices typically use two connectors, such as... Figure 1 As shown, the wiring is connected via insertion and threaded connection. While this design satisfies the need for quick connection to some extent, it has some shortcomings in practical operation.

[0004] Existing connection methods are susceptible to environmental influences. In some practical applications, the connectors may rub against external objects, causing rotation at the connection point. This rotation can lead to the connector sleeve loosening, resulting in the separation of the two connectors. This not only affects the normal operation of the monitoring system but may also cause equipment damage or data loss, causing unnecessary trouble and losses for users.

[0005] Therefore, to address the shortcomings of existing technologies, we propose a rapid connection device for low-voltage security monitoring lines. This device aims to solve the reliability issues of traditional connection devices by improving the connection structure and connection method. Utility Model Content

[0034] Please see Figures 2-8 This utility model provides a technical solution:

[0035] A rapid connection device for low-voltage security monitoring lines includes a first connector 100 and a second connector 200. The first connector 100 serves as one of the main parts of the connection device and cooperates with the second connector 200 to complete the line connection. The second connector 200 serves as the other main part of the connection device and connects the lines by inserting a connector plug 210 into the first connector 100. The right end of the first connector 100 has a connector socket 110 for receiving the connector plug 210 of the second connector 200 and is sealed and dustproof by a frame-shaped rubber gasket 400. The left end of the second connector 200 has a connector plug 210 that is adapted to the connector socket 110 and is inserted into the connector socket 110. Its positioning groove 211 cooperates with the plug post 330 for locking.

[0036] The upper and lower sides of the connector 210 are provided with positioning grooves 211. The positioning grooves 211 are used to receive the pins 330 and are mechanically locked to prevent the connector from loosening. The upper and lower sides of the first connector 100 are provided with anti-loosening locking parts 300 for fixing the position of the connector 210. The anti-loosening locking parts 300 are used to prevent the connector from loosening due to external force through the cooperation between the pins 330 and the positioning grooves 211. The connector 210 can only be disassembled when both anti-loosening locking parts 300 are unlocked at the same time, which further improves the safety of the connector.

[0037] The anti-loosening component 300 includes a circular housing 310, which is used to accommodate components such as the slider 320 and the spring 360 and provide sliding space. The circular housing 310 is welded and fixed to the first connector 100. The slider 320 is slidably connected inside the circular housing 310. The slider 320 is used to drive the insertion post 330 to move to realize the locking or unlocking function. The side of the slider 320 near the first connector 100 is provided with the insertion post 330. The end of the insertion post 330 away from the slider 320 is inserted into the positioning groove 211.

[0038] A rectangular connecting rod 340 is provided on the side of the slider 320 away from the first joint 100. The rectangular connecting rod 340 is used to connect the slider 320 and the pull block 350 to transmit manual operation force. The end of the rectangular connecting rod 340 away from the slider 320 passes through the inner wall of the circular housing 310 and is fixedly connected to the pull block 350. The pull block 350 is used for manual operation by the user to drive the slider 320 to move and unlock. The pull blocks 350 of the two anti-disengagement parts 300 can be pushed outward by the thumb and forefinger of one hand respectively for easy operation. A spring 360 is sleeved on the outside of the rectangular connecting rod 340. The spring 360 is located inside the circular housing 310 and is used to provide elastic restoring force so that the insertion post 330 remains locked in the absence of external force.

[0039] In this embodiment, a frame-shaped rubber pad 400 is provided on the inner wall of the opening of the docking port 110. The inner wall of the frame-shaped rubber pad 400 is tightly fitted with the outer wall of the docking plug 210. The frame-shaped rubber pad 400 is used to tightly fit with the outer wall of the docking plug 210, so as to play a role in waterproofing and dustproofing.

[0040] Specifically, the right end of the first connector 100 has two rectangular slots 120 arranged symmetrically in an upper and lower position, and the left end of the second connector 200 has two rectangular inserts 220. The two rectangular inserts 220 are respectively inserted into the two rectangular slots 120 to enhance the docking stability.

[0041] Furthermore, both rectangular inserts 220 have clearance holes c221 on their opposite sides, through which the insert post 330 passes. The clearance holes c221 provide a channel for the insert post 330 to pass through the rectangular inserts 220.

[0042] Furthermore, the first connector 100 has clearance holes a130 on both the upper and lower sides. The clearance holes a130 are connected to the clearance holes c221. The clearance holes a130 are used to provide a channel for the insertion post 330 to pass through the first connector 100.

[0043] Furthermore, clearance holes b140 are provided on both the upper and lower sides of the inner wall of the mating socket 110. The clearance holes b140 are used to ensure that the insertion post 330 can extend into the positioning groove 211 to complete the locking. The clearance holes b140 are connected to the clearance holes c221. The insertion post 330 passes through the clearance holes a130, c221 and b140 in sequence and is inserted into the positioning groove 211.

[0044] Furthermore, one end of the spring 360 abuts against the side of the slider 320 away from the first joint 100, and the other end of the spring 360 abuts against the inner wall of the circular housing 310.

[0045] In this embodiment, the quick-connect device for low-voltage security monitoring lines is used as follows: First, push the pull blocks 350 of the two anti-disengagement components 300 outward to prevent the plug 330 from obstructing the rectangular plug 220 from being inserted into the rectangular slot 120. Then, align the connector 210 at the left end of the second connector 200 with the connector socket 110 at the right end of the first connector 100, and insert the rectangular plug 220 of the second connector 200 into the rectangular slot 120 of the first connector 100, ensuring that the connector 210 is fully inserted into the connector socket 110. When the connector 210 is in place, release the pull blocks 350, and the spring 360 inside the anti-disengagement component 300 pushes the slider 32 through its elastic restoring force. The connector moves towards the first connector 100, causing the insertion pin 330 to pass through the clearance holes a130, c221, and b140 in sequence, and finally insert into the positioning groove 211 to complete the mechanical locking and prevent the connector from loosening. If the docking device needs to be disassembled, the pull blocks 350 of the two anti-disengagement locking parts 300 should be pushed outward with the thumb and forefinger of one hand. The pull blocks 350 drive the slider 320 to compress the spring 360 through the rectangular connecting rod 340, so that the insertion pin 330 is removed from the positioning groove 211 and moved out of the clearance hole c221. Then the docking plug 210 of the second connector 200 can be pulled out from the docking socket 110 of the first connector 100 to achieve quick separation.
