Description

Technical Field

[0001] This utility model relates to the field of building controller technology, and in particular to an intelligent building control device that is easy to wire. Background Technology

[0002] Traditional intelligent building control equipment (such as access control systems and fire controllers) generally uses bolt-pressed terminals. This design has the following technical drawbacks: When wiring intelligent building control equipment, multiple wires sometimes need to be connected to a single terminal. Traditional control equipment terminals mostly use bolts to clamp the wires, which can easily cause uneven bolt torque, leading to unbalanced contact pressure distribution, resulting in wire detachment and poor contact, making it inconvenient for operators. To address these drawbacks, we propose an intelligent building control device that facilitates wiring. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent building control device that is easy to wire.

[0004] To address the problems existing in the prior art, the present invention adopts the following technical solution: an intelligent building control device that is easy to wire, including an access control main controller. The upper surface of the access control main controller is provided with multiple wiring slots at equal intervals. The inner wall of the wiring slot is vertically fixed with conductive pins. The conductive pins are connected to the wiring contacts inside the access control main controller. The wiring slot is provided with a detachable parallel wiring mechanism.

[0005] The paralleling mechanism includes a housing with multiple independent wire channels, an installation cavity opened in the inner wall of the housing, a clamping component disposed in the installation cavity, and a locking component disposed on the side of the housing, wherein the wire channels and the installation cavity are interconnected.

[0006] The clamping assembly includes a conductive frame embedded in the inner wall of the mounting cavity, and a first spring conductive sheet fixedly installed at one end of the conductive frame;

[0007] The conductive frame has a fixing component inside for fixing the conductive pin. The fixing component includes a conductive ring fixedly installed inside the conductive frame, and a plurality of second spring conductive plates are arranged in a circumferential array on the inner wall of the conductive ring.

[0008] Preferably, the conductive frame is integrally formed with the first spring conductive sheet.

[0009] Preferably, the free end of the first spring conductive sheet extends to the outlet of the wire channel and contacts the surface of the conductive frame.

[0010] Preferably, the lower surface of the housing has a through hole for the conductive pin to pass through, the through hole is connected to the mounting cavity, and the through hole is coaxially arranged with the conductive ring.

[0011] Preferably, a cover plate is fixedly installed on the upper surface of the access control main controller by bolts, and the cover plate is used to cover the wiring slot.

[0012] Preferably, limit blocks are fixedly installed on the two inner sidewalls of the wiring groove, and limit grooves are opened at corresponding positions on the housing.

[0013] Preferably, the locking assembly includes a threaded hole on the left side of the housing and a locking bolt threaded into the inner wall of the threaded hole, the threaded hole being in communication with the wire channel.

[0014] Preferably, the conductive pin, conductive frame, first spring conductive sheet, conductive ring, and second spring conductive sheet are all made of T2 copper.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By designing a housing with multiple independent wire channels, multiple wires can be reliably connected on the same terminal (conductive pin) through a paralleling mechanism. The detachable paralleling mechanism completely solves the technical problems of uneven contact pressure, easy loosening, poor contact, and cumbersome operation that exist in traditional bolt-type terminals when connecting multiple wires in parallel. It realizes efficient, reliable, stable and easy-to-maintain multi-wire connection, significantly improving the wiring convenience and operational reliability of intelligent building control equipment.

[0017] 2. The parallel wiring mechanism adopts a modular and detachable design, and the wiring work can be completed in advance in an offline state. Simply insert multiple wires into the corresponding wire channels of the housing, and the wires will be initially clamped by the first spring conductive plate. Tightening the locking bolt will complete the fixing of the wires on the parallel wiring mechanism. The entire wiring process does not require tightening bolts to fix multiple wires one by one on the narrow equipment body, which provides more operating space and significantly improves wiring efficiency. The parallel wiring mechanism with pre-installed wires can be inserted into the wiring slot of the access control main controller to complete the electrical connection with the equipment. The plug-in connection greatly simplifies the on-site installation and maintenance steps. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-6 This utility model provides a technical solution: an intelligent building control device that is easy to wire, including an access control main controller 10. The upper surface of the access control main controller 10 is provided with multiple wiring slots at equal intervals. The inner wall of the wiring slot is vertically fixed with conductive pins 11. The wiring slot is a physical interface for connecting external wires, and the conductive pins 11 inside it are directly connected to the internal circuit of the device.

[0028] The wiring slot is equipped with a detachable paralleling mechanism, which includes a housing 21 with multiple independent wire channels 20, an installation cavity opened in the inner wall of the housing 21, a clamping component in the installation cavity, and a locking component on the side of the housing 21. The wire channels 20 are interconnected with the installation cavity, and the paralleling mechanism is inserted into the wiring slot to complete the final connection.

[0029] The clamping assembly includes a conductive frame 30 embedded in the inner wall of the mounting cavity, and a first spring conductive sheet 31 fixedly installed at one end of the conductive frame 30. The conductive frame 30 serves as the basic conductor of the "female end" for electrical connection of the wires and is integrally formed with the first spring conductive sheet 31. The free end of the first spring conductive sheet 31 extends to the outlet of the wire channel 20. The first spring conductive sheet 31 is a key elastic component, and its free end is initially in contact with the conductive frame 30.

[0030] When the wire is inserted, the wire pushes its free end open, and the first spring conductive plate 31 undergoes elastic deformation. Relying on the elastic restoring force, the first spring conductive plate 31 presses the wire tightly against the surface of the conductive frame 30, realizing preliminary electrical conduction and mechanical fixation. The first spring conductive plate 31 provides continuous and adaptive pressure to compensate for minor changes in the wire. The housing 21 is a modular basic structure, and multiple independent wire channels 20 allow single wires to be inserted and clamped independently without interference, solving the problems of multi-wire entanglement and uneven pressure.

[0031] The locking assembly includes a threaded hole 70 on the left side of the housing 21 and a locking bolt 71 threaded into the inner wall of the threaded hole 70. The threaded hole 70 is connected to the wire channel 20. The locking bolt 71 provides auxiliary mechanical locking. When screwed in, the end of the locking bolt 71 directly presses against the wire located in the wire channel 20, which greatly increases the pull-out resistance of the wire and prevents accidental pull-out.

[0032] The conductive frame 30 has a fixing component inside for fixing the conductive pin 11. The fixing component includes a conductive ring 40 fixedly installed inside the conductive frame 30. The inner wall of the conductive ring 40 has a circumferential array of multiple second spring conductive plates 41. The lower surface of the housing 21 has a through hole for the conductive pin 11 to pass through. The through hole is interconnected with the mounting cavity and is coaxially arranged with the conductive ring 40. The conductive ring 40 is fixed inside the conductive frame 30 and serves as the "female" interface for connecting to the conductive pin 11 of the main controller. The second spring conductive plates 41 are circumferentially arrayed on the inner wall of the conductive ring 40. When the conductive pin 11 is inserted into the conductive ring 40 through the through hole at the bottom of the housing 21, the conductive pin 11 causes the second spring conductive plates 41 to elastically deform (open), and then the second spring conductive plates 41 are held tightly by their elastic restoring force. This multi-point elastic contact ensures a highly reliable and vibration-resistant electrical connection.

[0033] Limiting blocks 60 are fixedly installed on the two inner side walls of the wiring groove, and limiting grooves 61 are opened at the corresponding positions on the housing 21. When inserting the paralleling mechanism, the limiting grooves 61 on the housing 21 must be aligned and matched with the limiting blocks 60 on the inner wall of the wiring groove. This ensures that the insertion direction is correct and that the conductive pins 11 can be accurately aligned with the center through hole of the conductive ring 40 after the housing 21 is inserted into place.

[0034] The conductive pin 11, conductive frame 30, first spring conductive sheet 31, conductive ring 40 and second spring conductive sheet 41 are all made of T2 copper. The conductive pin 11, as the "male" contact, is inserted into the conductive ring 40 of the paralleling mechanism and is held tightly by the second spring conductive sheet 41 to conduct electricity.

[0035] A cover plate 50 is bolted to the upper surface of the access control main controller 10. The cover plate 50 is used to cover the wiring slot. The cover plate 50 is fastened to the upper surface of the access control main controller 10 by bolts. Its lower surface covers and presses down on the upper edge of the parallel wiring mechanism housing 21 inserted into the wiring slot. This provides downward pressure to prevent the parallel wiring mechanism from coming loose upward due to vibration or accidental force, ensuring a stable connection between the conductive pin 11 and the conductive ring 40. At the same time, it covers the wiring area, improving security and aesthetics.

[0036] Specifically, the working principle and operation method of this utility model are as follows:

[0037] This device replaces the traditional wiring method with a modular, pluggable parallel wiring mechanism. In the offline state, the operator first uses the first spring conductive plate 31 in the parallel wiring mechanism to elastically clamp and mechanically lock the locking bolt 71 to independently and reliably pre-fix multiple wires. Then, the entire parallel wiring mechanism is inserted into the wiring slot on the access control main controller 10. The electrical connection with the device is completed by the multiple points of tight engagement between the conductive pin 11 and the second spring conductive plate 41 of the conductive ring 40. The cover plate 50 provides final compression protection, which perfectly solves the pain point of traditional bolt crimping when connecting multiple wires.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
