Description

Technical Field

[0001] This utility model relates to the field of fire alarm control panel technology, specifically a novel wiring structure for a fire alarm control panel. Background Technology

[0002] With the acceleration of urbanization and the increasing number of various buildings and facilities, fire safety has become a crucial link in protecting people's lives and property. As the core control device of a fire alarm system, the performance and reliability of the fire alarm control panel directly affect whether the entire system can detect, alarm, and activate corresponding fire-fighting linkage control functions in a timely and accurate manner during a fire. In recent years, fire alarm systems have continuously evolved technologically, developing towards intelligence, networking, and integration, which has led to increasingly higher requirements for fire alarm control panels.

[0003] Traditional fire alarm control panel wiring often relies on a large number of screw-fastened terminal blocks. This wiring method requires operators to use tools to tighten the screws one by one to secure the wires, which is extremely time-consuming. Especially in large-scale building projects, it is necessary to connect numerous lines, such as hundreds of fire detectors and dozens of linkage control devices. Wiring in the traditional way often consumes a lot of manpower and time costs, seriously delaying the project schedule. Therefore, a new wiring structure for fire alarm control panels is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new wiring structure for a fire alarm control panel, which addresses the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a new wiring structure for a fire alarm host, including a wiring panel and a cable. The wiring panel has a wiring port on the front, the cable is placed in the wiring port, a terminal port is provided in the wiring port, the terminal head of the cable is inserted into the terminal port, and a connecting mechanism is provided on the cable.

[0006] The connecting mechanism includes: a housing, which is fixedly sleeved on the outer wall of the cable and inserted into the connector port; two sliding plates are slidably connected to the inner wall of the housing; wedge-shaped blocks are fixedly connected to the opposite sides of the two sliding plates; slide bars are fixedly connected to the opposite surfaces of the two sliding plates; a sliding sleeve is fixedly connected to the left sliding plate; a slide rod is slidably connected to the inner wall of the sliding sleeve; the right end of the slide rod is fixedly connected to the right sliding plate; a spring is fixedly connected to the left end of the slide rod; and the other end of the spring is fixedly connected to the inner wall of the sliding sleeve.

[0007] Preferably, the left and right sides of the housing are provided with sliding holes II, and the inner walls of the left and right sides of the wiring port are provided with slots. The two wedge-shaped blocks pass through the two sliding holes II and engage with the slots. The slots limit the wedge-shaped blocks, and the wedge-shaped blocks limit the housing, thereby fixing the housing in the wiring port.

[0008] Preferably, the front of the housing has two sliding holes, and the two slide bars pass through the two sliding holes and extend forward.

[0009] Preferably, there are two of each of the sliding sleeve, sliding rod, and spring, and they are arranged opposite to each other on the upper and lower sides of the cable.

[0010] Preferably, each of the two sliders has a thumb groove, and they are arranged opposite to each other.

[0011] Preferably, the front of the wiring panel is provided with an identification groove, which is located above the wiring port, and an identification plate is attached to the inner wall of the identification groove.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This new wiring structure for a fire alarm control panel involves inserting the housing into the wiring port. Under the action of a spring, the sliding sleeve and sliding rod are pushed, thereby pushing the sliding plate. This causes the wedge-shaped locking block to pop out and lock into the slot, thus completing the cable connection. No tools are needed to tighten screws. The operation is simple and quick, greatly shortening the wiring time of a single cable, effectively improving wiring efficiency, and accelerating the project progress.

[0014] 2. This new wiring structure for a fire alarm control panel features a thumb groove for easy pressing of the slider, preventing finger slippage. An identification plate attached to the marking groove allows operators to quickly identify the corresponding function information of the wiring ports, facilitating later maintenance and repair, improving work efficiency, and reducing maintenance costs.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component 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 utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0025] Please see Figure 1-5One embodiment of this utility model is as follows: A novel wiring structure for a fire alarm control panel includes a wiring panel 1 and a cable 3. The wiring panel 1 has a wiring port 2 on its front side. The cable 3 is disposed within the wiring port 2, which has a terminal opening. The terminal of the cable 3 is inserted into the terminal opening. A connecting mechanism 4 is provided on the cable 3. The connecting mechanism 4 includes a housing 41, which is fixedly sleeved on the outer wall of the cable 3 and inserted into the wiring port 2. Two sliding plates 42 are slidably connected to the inner wall of the housing 41. Wedge-shaped locking blocks 43 are fixedly connected to the sides of the two sliding plates 42 that are far apart from each other and are arranged opposite to each other. Sliding holes 49 are respectively opened on the left and right sides of the housing 41. Slots are respectively opened on the inner walls of the left and right sides of the wiring port 2. The two wedge-shaped locking blocks 43 pass through the two sliding holes 49 and engage with the slots. The slots limit the wedge-shaped locking blocks 43, and the wedge-shaped locking blocks 43 limit the housing 41, thereby fixing the housing 41 within the wiring port 2. Two sliding plates 42 are fixedly connected to opposite sides with sliding bars 44. Two sliding holes 48 are opened on the front of the housing 41. The two sliding bars 44 pass through the two sliding holes 48 and extend forward. A sliding sleeve 45 is fixedly connected to the left sliding plate 42. A sliding rod 46 is slidably connected to the inner wall of the sliding sleeve 45. The right end of the sliding rod 46 is fixedly connected to the right sliding plate 42. A spring 47 is fixedly connected to the left end of the sliding rod 46. The other end of the spring 47 is fixedly connected to the inner wall of the sliding sleeve 45. There are two of each of the sliding sleeve 45, sliding rod 46, and spring 47, which are arranged opposite each other on the upper and lower sides of the cable 3. By inserting the housing 41 into the wiring port 2, the sliding sleeve 45 and sliding rod 46 are pushed by the elastic force of the spring 47, thereby pushing the sliding plate 42. This causes the wedge-shaped locking block 43 to pop out and lock into the slot, thus completing the connection of the cable 3. No tools are needed to tighten the screws. The operation is simple and quick, greatly shortening the wiring time of a single cable 3, effectively improving wiring efficiency, and speeding up the project progress.

[0026] Working principle: When the housing 41 is inserted into the connector 2, the wedge-shaped block 43 is squeezed by the inner wall of the connector 2 and retracts into the housing 41, thereby driving the two slide plates 42 to move closer to each other. This causes the slide rod 46 to slide along the inner wall of the slide sleeve 45 and compress the spring 47. When the wedge-shaped block 43 reaches the slot position, it pushes the slide sleeve 45 and the slide rod 46 under the elastic force of the spring 47, thereby pushing the slide plate 42. This causes the wedge-shaped block 43 to pop out and lock into the slot, thus fixing the housing 41 and the cable 3 in the connector 2, thereby completing the connection of the cable 3. Conversely, by pressing the thumb groove 5, the two slide bars 44 are forced to move closer to each other, thereby causing the slide bars 44 to move the slide plate 42. The slide plate 42 causes the wedge-shaped block 43 to retract and disengage from the slot, thereby releasing the limit and pulling the housing 41 and the cable 3 out of the connector 2.

[0027] Please see Figure 1-5Based on the above embodiments, in another embodiment of this utility model, thumb grooves 5 are respectively provided on the two slide bars 44 and are arranged opposite to each other. The thumb grooves 5 make it convenient for operators to press the slide bars 44 and avoid finger slippage. The front of the wiring panel 1 is provided with an identification groove 6, which is located above the wiring port 2. An identification plate 7 is attached to the inner wall of the identification groove 6. By attaching the identification plate 7 in the identification groove 6, it is convenient for operators to quickly identify the functional information corresponding to the wiring port 2, which facilitates later maintenance and repair, improves work efficiency, and reduces maintenance costs.

[0028] Working principle: The thumb groove 5 allows operators to press the slide bar 44 easily, preventing fingers from slipping. The label 7 is attached to the label groove 6, which allows operators to quickly identify the function information corresponding to the wiring port 2, facilitating later maintenance and repair.

[0029] This utility model provides a novel wiring structure for a fire alarm control panel. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly described in this embodiment can be implemented using existing technology.
