Description

Technical Field

[0001] This utility model relates to the field of terminal block adapter technology, specifically a convenient terminal block adapter for switch machines. Background Technology

[0002] Electric switch machines, as key equipment in railway signaling systems, are widely used in various railway stations, undertaking the important tasks of switch switching and locking, and reflecting the position status of switches. During long-term use, some drawbacks have been found in the internal wiring method using ribbed contacts. For example, under long-term vibration and electrical wear, the ribbed contacts are prone to poor contact, leading to unstable signal transmission, which in turn affects the normal operation of the switches and poses safety hazards to railway operations. Furthermore, the ribbed contact wiring method is complex to operate during maintenance and repair, requiring significant time and manpower, increasing maintenance costs and equipment downtime, and affecting the normal operational efficiency of railway lines. Utility Model Content

[0003] The purpose of this utility model is to provide a convenient terminal block adapter for switch machines, which enables quick and reliable connection between the internal wiring of the switch machine and external testing instruments and control circuits during switch machine installation, commissioning, daily maintenance and troubleshooting, replacing the traditional fixed terminal block and solving the problem of maintenance requiring a lot of time and manpower.

[0004] To address the problems of existing technologies, this utility model provides a convenient terminal block adapter for a switch machine, comprising a first terminal block assembly and a second terminal block assembly. The first and second terminal block assemblies are detachably installed within the space inside the switch machine. The first terminal block assembly includes a first mounting bracket, with a first mounting rail fixed to its top along its length. The first terminal block assembly also includes a first spring-loaded terminal slidably disposed on the top of the first mounting rail. Two first limiting seats, slidably disposed on the first mounting rail and distributed at both ends of the first spring-loaded terminal, are used to fix the first spring-loaded terminal. The second terminal block assembly includes a second mounting bracket, with a second mounting rail fixed to its top along its length. The second terminal block assembly also includes a second spring-loaded terminal disposed on the top of the second mounting rail. Two second limiting seats, slidably disposed on the second mounting rail and distributed at both ends of the second spring-loaded terminal, are used to fix the second spring-loaded terminal.

[0005] Preferably, the top of the first mounting rail has protrusions on both sides, and the bottom of the first limiting seat has a buckle that cooperates with the protrusions.

[0006] Preferably, the bottom of the first limiting seat is elastic, and the buckle of the first limiting seat can be engaged with the protrusion of the first mounting rail.

[0007] Preferably, the cross-section of the first mounting bracket is "L" shaped, and a plurality of first reserved holes are provided on the vertical side of the first mounting bracket.

[0008] Preferably, the top of the second mounting bracket also has a protrusion, and the bottom of the second limiting seat has a buckle that cooperates with the protrusion.

[0009] Preferably, the bottom of the second limiting seat is elastic, and the buckle of the second limiting seat can be engaged with the protrusion on the second mounting rail.

[0010] Preferably, the second mounting bracket has a plurality of second reserved holes.

[0011] Preferably, the first mounting bracket, the first mounting rail, the first limiting seat, the second mounting bracket, the second mounting rail, and the second limiting seat are made of lightweight insulating material.

[0012] The advantages of this utility model compared to the prior art are: This application uses a first spring-crushed terminal and a second spring-crushed terminal as the core wiring units, which are integrated into the convenient housing of the switch machine interface, forming a "plug-and-play" adapter structure that enables rapid connection with the switch machine line. Regarding the installation and fixing components, the first mounting bracket, first mounting rail, first limit seat, second mounting bracket, second mounting rail, and second limit seat are all made of lightweight insulating material. This material not only meets structural strength requirements but also ensures electrical safety through excellent insulation performance. These components are connected and fixed to the switch machine via magnetic or snap-fit ​​structures, allowing for temporary installation without tools. This fundamentally solves the problem of reliance on tools and cumbersome procedures in traditional terminal assembly and disassembly, significantly simplifying the on-site installation process. In terms of wiring performance, the first and second spring-crushed terminals adopt a spring-crushed design. Their internal spring structure generates stable pressure through elastic deformation, achieving a "plug-and-play" connection effect for the wires. Compared to traditional screw-fastened terminals, this design reduces wiring time by over 80%, significantly improving the overall efficiency of switch machine maintenance and commissioning. Simultaneously, the continuous pressure generated by the spring clamp effectively counteracts contact gaps caused by environmental factors such as vibration and temperature changes, reducing the risk of poor contact and thus decreasing the probability of signal transmission failures. Furthermore, since screw fastening is unnecessary, operators do not need to carry additional tightening tools, reducing tool carrying burden and completely eliminating potential equipment hazards and safety risks caused by loose or lost screws. In terms of compatibility, both the first and second spring clamp terminals are compatible with test leads and control circuits of different specifications. The sliding adjustment of the first and second limit seats in the first and second mounting rails allows for easy replacement of the first and second spring clamp terminals, flexibly adapting to the line interface requirements of different switch machine models and improving the structure's versatility and application range.

[0020] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1-6As shown, this utility model provides a convenient terminal conversion device for a switch machine, including a first terminal assembly 1 and a second terminal assembly 2. The first terminal assembly 1 and the second terminal assembly 2 can be detachably installed in the space inside the switch machine. The first terminal assembly 1 includes a first mounting bracket 11, and a first mounting rail 12 is fixed to the top of the first mounting bracket 11 along its length direction. The first terminal assembly 1 also includes a first spring-loaded terminal 14 slidably disposed on the top of the first mounting rail 12. Two first limiting seats 13 are slidably disposed on the first mounting rail 12 and distributed at both ends of the first spring-loaded terminal 14 for fixing the first spring-loaded terminal 14. The second terminal assembly 2 includes a second mounting bracket 21, and a second mounting rail 22 is fixed to the top of the second mounting bracket 21 along its length direction. The second terminal assembly 2 also includes a second spring-loaded terminal 24 disposed on the top of the second mounting rail 22. Two second limiting seats 23 are slidably disposed on the second mounting rail 22 and distributed at both ends of the second spring-loaded terminal 24 for fixing the second spring-loaded terminal 24. The first mounting rail 12 and the second mounting rail 22 provide sliding tracks for the corresponding spring-crimped terminals (first spring-crimped terminal 14, second spring-crimped terminal 24) and limiting seats (first limiting seat 13, second limiting seat 23), allowing the above components to adjust their positions along the length direction to adapt to the spacing requirements of different specifications of conductors or switch machine lines. The first spring-crimped terminal 14 and the second spring-crimped terminal 24, as the core conductive connection components of the device, adopt a spring-crimped structure design. Their main function is to achieve rapid electrical connection of the conductors: when an external test conductor or control circuit is inserted into the terminal, the internal spring generates continuous pressure through elastic deformation, ensuring tight contact between the conductor and the conductive part of the terminal, achieving the effect of "insertion and connection"; at the same time, the continuous pressure of the spring can offset the contact gap caused by vibration and temperature changes, ensuring the stability of signal transmission.

[0022] The first mounting rail 12 has protruding strips on both sides of its top, and the bottom of the first limiting seat 13 has a buckle that cooperates with the protruding strips. The bottom of the first limiting seat 13 is elastic, and the buckle of the first limiting seat 13 can be locked onto the protruding strips of the first mounting rail 12. The first mounting bracket 11 has an "L" shaped cross-section, and several first reserved holes 111 are opened on the vertical side of the first mounting bracket 11.

[0023] The bottom of the first limiting seat 13 is provided with a matching buckle structure corresponding to the protrusion of the first mounting rail 12, and the bottom of the first limiting seat 13 has elastic deformation capability. In the assembled state, the buckle of the first limiting seat 13 engages with the protrusion of the first mounting rail 12 through the pre-tightening force generated by the elasticity of the bottom, forming a reliable mechanical lock, which can effectively limit the unintended sliding of the first limiting seat 13 along the first mounting rail 12 and ensure its limiting stability for the first spring-pressed terminal 14. When it is necessary to adjust the position of the first limiting seat 13, by applying an external force perpendicular to the mounting rail direction to the first limiting seat 13, its bottom can be elastically deformed, releasing the engagement state between the buckle and the protrusion. At this time, the first limiting seat 13 can slide freely along the length direction of the first mounting rail 12; after sliding to the target position, the external force is removed, the bottom elasticity is restored, the buckle re-engages with the protrusion, and the first limiting seat 13 is repositioned. This structural design ensures the reliability of the first limiting seat 13 in the working state and also gives it convenient position adjustment capability to adapt to the fixing requirements of the first spring-pressed terminal 14 of different specifications.

[0024] The second mounting bracket 21 also has a protruding strip on its top, and the bottom of the second limiting seat 23 has a buckle that cooperates with the protruding strip. The bottom of the second limiting seat 23 is elastic, and the buckle of the second limiting seat 23 can be engaged with the protruding strip on the second mounting rail 22. The second mounting bracket 21 has several second reserved holes 211.

[0025] The bottom of the second limiting seat 23 is provided with a matching buckle corresponding to the protrusion on the top of the second mounting bracket 21, and the bottom of the second limiting seat 23 has elastic deformation capability. In the assembled state, the buckle reliably engages with the protrusion through the pre-tightening force generated by the elasticity of the bottom, thereby locking the position of the second limiting seat 23 on the second mounting bracket 21. This effectively prevents unexpected sliding during device operation or switch machine vibration, ensuring the limiting stability of the second spring-pressed terminal 24. When it is necessary to adjust the position of the second limiting seat 23, an external force perpendicular to the length direction of the protrusion is applied to it, which causes the bottom to elastically deform, releasing the engagement between the buckle and the protrusion. At this time, the second limiting seat 23 can slide freely along the length direction of the protrusion. After sliding to the target position, the external force is removed, the bottom elasticity is restored, and the buckle re-engages with the protrusion, completing the position fixation. This structure ensures the working stability of the second limit seat 23 and provides it with convenient adjustment capabilities to adapt to the fixing requirements of second spring-loaded terminals 24 of different specifications.

[0026] The first mounting bracket 11, the first mounting rail 12, the first limiting seat 13, the second mounting bracket 21, the second mounting rail 22, and the second limiting seat 23 are made of lightweight insulating material.

[0027] The lightweight design significantly reduces the weight of each component, thus lessening the load on the internal installation space of the switch machine and adapting to its compact structural layout. It also facilitates quick handling and operation by personnel during installation and adjustment, improving on-site convenience. Insulation performance is crucial for ensuring electrical safety. These components, serving as structural supports and guiding elements, effectively block unexpected conductive paths, preventing short circuits, leakage, or signal interference caused by component conductivity, ensuring the stability and safety of the switch machine's signal transmission.

[0028] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
