Description

Technical Field

[0001] This utility model relates to the field of railway signaling equipment technology, specifically to a metal clip structure for a railway signal relay base. Background Technology

[0002] The metal clip in the base of a railway signal relay is a key component. It is a metal part used to connect the relay pins and the wiring. It is usually installed in a conductive groove in the relay base and connected to the relay pins. Its main functions are as follows:

[0003] Fixed relay: Metal clips can fix the relay pins in the conductive grooves of the relay base, ensuring the stability of the relay during use;

[0004] Connection circuit: The metal clips, as conductive materials, can connect the relay pins to the circuit, enabling the circuit to function properly;

[0005] Conducting current: As part of the circuit, the metal clip can conduct current, ensuring signal transmission and circuit closure.

[0006] The metal clips of the relay base are an important component of the relay, and their quality and performance directly affect the stability and reliability of the relay.

[0007] Currently used metal clips for relay bases have significant drawbacks. In relay bases with limited space, multiple metal clips are required, such as... Figures 1 to 3 The diagram shows a commonly used base and clips with two rows of 28 clips. The spacing between the welding terminals on the clips is very limited. The cable ends of the clips have open, closed structures. After welding the cable, an insulating flexible tube needs to be added along the direction of the cable end on the clip. This means the cable can only be welded on the upper or lower surface of the cable end on the clip, perpendicular to the base and along the direction of the cable end on the clip. Therefore, the limited operating space during cable welding makes construction difficult, making it hard to achieve the required welds that are firm and smooth, without false solder joints or solder burrs. This can easily lead to short circuits at the joints, posing a serious safety hazard. Utility Model Content

[0008] To address the aforementioned issues, this utility model provides a metal clip structure for a railway signal relay base. This metal clip structure reduces the required operating space and improves welding quality. The metal clip structure, composed of two independent metal plates and featuring an open, holeless design at the cable end, allows the cable to be directly welded between the two open metal plates, significantly reducing the required operating space and facilitating welding operations. Furthermore, the open design at the cable end allows for free adjustment of the cable's position between the two metal plates, making it easier to achieve a firm, smooth weld without false solder joints or solder burrs, effectively preventing safety hazards such as short circuits caused by poor welding.

[0009] The technical solution of this utility model is as follows:

[0010] A metal clip structure for a railway signal relay base includes two metal plates and a fixing component. The two metal plates are fixedly connected as one unit by the fixing component. From top to bottom, the metal plates consist of a relay insertion end guide plate, a relay insertion end clip, and a welding cable end. A gap for accommodating the cable is provided between the two metal plates.

[0011] The inner surfaces of the welding cable ends of the two metal sheets are chemically galvanized.

[0012] An elastic clip is provided on the outside of one of the metal sheets.

[0013] The two metal plates are fixedly connected by several fixing components.

[0014] The fixing component consists of a middle section and connecting sections on both sides of the middle section. The outer contour dimension of the middle section is larger than that of the connecting section. Mounting holes are provided on the metal plates, which are larger than the outer contour dimension of the connecting section but smaller than that of the middle section. After the mounting holes of the two metal plates pass through the connecting sections on both sides and abut against the two ends of the middle section, the metal plates are fixedly connected to the connecting sections.

[0015] The cross-sections of the intermediate and connecting sections are not cylindrical, and the mounting holes on the metal sheets are not circular.

[0016] Optionally, the cross-section of the intermediate section and the connecting section is square, and the mounting holes on the metal sheet are square holes that are clearance-fitted with the connecting section and smaller than the outer contour dimension of the intermediate section.

[0017] Optionally, the cross-sections of the intermediate section and the connecting section are polygonal, and the mounting holes on the metal sheet are polygonal holes that fit the connecting section with a clearance and are smaller than the outer contour size of the intermediate section.

[0018] Specifically, the metal sheet is welded to the connecting section.

[0019] The thickness of the fixed component shall not exceed the thickness of the reserved hole in the relay base.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. The present invention discloses a metal clip structure for a railway signal relay base. This metal clip structure for a railway signal relay base can reduce the operating space requirements: the metal clip structure is composed of two independent metal plates, and the welding cable end adopts an open, holeless design. This structure allows the cable to be directly welded between the two open metal plates at the welding cable end, which greatly reduces the operating space requirements and facilitates welding operations by construction personnel.

[0022] 2. The present invention discloses a metal clip structure for a railway signal relay base. This metal clip structure for a railway signal relay base can improve welding quality: because the welding cable end is designed with an opening, the cable can be freely adjusted between the two metal clips, thereby making it easier to achieve the construction process requirements such as firm and smooth wire end welding, no false welding or solder burrs falling off, and effectively avoiding safety hazards such as short circuits caused by poor welding.

[0023] 3. The present invention discloses a metal clip structure for a railway signal relay base.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0036] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0037] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0038] like Figures 4 to 6 As shown, the relay base metal clip structure includes a metal plate 1 and a fixing component 2. The metal plate 1 consists of two opposing pieces. One piece comprises a relay-end guide plate 101, a relay-end clip 102, an elastic clip 103, and a welding cable end 104. The other piece also comprises the same components. The relay-end guide plate 101 guides the metal plate 1 accurately into the conductive groove of the relay base, serving a positioning function. The relay-end clip 102 makes close contact with the relay pins, achieving reliable electrical connection and mechanical fixation. The elastic clip 103, located on the outer side of the metal plate 1, has a certain degree of elasticity and can hold the metal plate 1 in place after it is inserted into the pre-drilled hole in the relay base, preventing it from falling out. The welding cable end 104 is used for welding cables, enabling the relay to connect to external circuitry.

[0039] Metal sheet 1 is made of a metallic material with good electrical conductivity and corrosion resistance. In railway signaling systems, current needs to be transmitted stably; therefore, metal sheet 1 must possess good conductivity to reduce losses during current transmission. Simultaneously, due to the harsh railway environment, metal sheet 1 may be affected by factors such as moisture and corrosion, so it needs good corrosion resistance to ensure its long-term stable operation. Common metallic materials such as copper alloys, with their good electrical conductivity and corrosion resistance, are ideal choices for manufacturing metal sheet 1.

[0040] The inner surface of the welding cable end 104 is treated with chemical zinc plating. Chemical zinc plating is a process that forms a zinc coating on the metal surface, which can prevent the metal sheet 1 from oxidizing and simplify the welding process. Zinc has good chemical stability and can form a dense protective film on the surface of the metal sheet 1, preventing the metal sheet 1 from reacting chemically with oxygen, moisture, etc. in the air and being oxidized. During the welding process, the zinc coating can also act as a flux, reducing the welding difficulty and improving the welding quality.

[0041] The cable end 104 is open and without holes. During cable welding, the cable is directly welded between the two open metal plates 1 of the cable end 104. This structure significantly reduces the required operating space, allowing workers to perform welding operations more conveniently on relay bases with limited space. Furthermore, because the cable is welded between the two metal plates 1, issues such as cold solder joints or solder burrs falling off are avoided, improving the reliability and safety of the welding process.

[0042] The fixing component 2 is a non-cylindrical structure, which prevents the metal plate 1 from rotating. For example... Figure 7 As shown, the fixing component 2 consists of a middle section 21 and connecting sections 22 on both sides of the middle section 21. The outer contour dimension of the middle section 21 is larger than the outer contour dimension of the connecting sections 22. It should be noted that... Figure 7 To more clearly demonstrate the structure of the fixing component 2, an enlarged version has been created, which may not perfectly match the actual structural proportions. This structure allows the fixing component 2 to provide reliable support and positioning when fixing the metal sheet 1.

[0043] Mounting holes are provided on the metal plates 1, which are larger than the outer contour of the connecting section 22 but smaller than the outer contour of the intermediate section 21. After the mounting holes of the two metal plates 1 pass through the connecting sections 22 on both sides and abut against the two ends of the intermediate section 21, the metal plates 1 are fixedly connected to the connecting sections 22. This design ensures that the metal plates 1 can be smoothly installed on the fixed component 2, and also ensures the spacing between the two metal plates 1 by the restriction of the intermediate section 21.

[0044] The non-cylindrical structure ensures that the two metal clips 1 will not rotate. In railway signaling systems, the metal clips need to maintain a stable posture to ensure a reliable connection between the relay pins and the circuit. If the metal clips 1 rotate, it may cause the connection to loosen, affecting signal transmission and the normal operation of the circuit. The non-cylindrical fixing component 2 effectively prevents this from happening, improving the stability and reliability of the metal clips.

[0045] The cross-sections of the intermediate section 21 and the connecting section 22 can be square, and the mounting holes on the metal sheet 1 are square holes that fit the connecting section 22 with a clearance fit and are smaller than the outer contour dimension of the intermediate section 21. The square structure is simple, easy to process, and provides good anti-rotation performance. Alternatively, the cross-sections of the intermediate section 21 and the connecting section 22 can also be polygonal (e.g., hexagonal), and the mounting holes on the metal sheet 1 are polygonal holes that fit the connecting section 22 with a clearance fit and are smaller than the outer contour dimension of the intermediate section 21. The polygonal structure can be designed according to actual needs to further improve anti-rotation performance.

[0046] The function of the middle section 21 is to ensure the spacing between the two metal sheets 1, and the length of the middle section 1 is the size of the spacing.

[0047] Optionally, the metal sheet 1 is welded to the connecting segment 22. Welding is a reliable connection method that ensures the connection strength between the metal sheet 1 and the fixed component 2. During the welding process, welding parameters, such as welding current and welding time, need to be controlled to ensure welding quality. After welding, the welded area also needs to be inspected to ensure there are no defects such as incomplete welds or missing welds. Alternatively, after installing the metal sheet 1 onto the connecting segment 22, the two ends of the connecting segment 22 can be deformed by striking the head of the connecting segment 22 with a rivet hammer, similar to riveting, to secure the metal sheet 1 to the connecting segment 22.

[0048] The two metal sheets 1 are fixedly connected by a number of fixing components 2. The number and layout of the fixing components 2 can be designed according to the size of the metal sheets 1 and actual needs. Generally, the fixing components 2 should be evenly distributed on the metal sheets 1 to ensure the stability and flatness of the metal sheets 1 after fixing.

[0049] The thickness of the fixing component 2 shall not exceed the thickness of the pre-drilled hole in the relay base. This requirement is to facilitate the smooth insertion of the soldered cable end 104 into the pre-drilled hole in the base. If the thickness of the fixing component 2 is too large, it may cause the metal piece 1 to be obstructed when inserted into the pre-drilled hole in the base, affecting the smooth installation. Therefore, when designing the fixing component 2, the size of the pre-drilled hole in the relay base needs to be fully considered to ensure that the thickness of the fixing component 2 meets the requirements.

[0050] Compared to existing signal cabinet base structures, this invention provides a novel metal clip structure for railway signal relay bases. The metal clip consists of two independent metal plates. The cable welding end of the clip is open and without holes. The inner surface of the terminal plate is chemically galvanized. The cable is directly welded between the two open metal plates at the cable welding end. This structure significantly reduces the required operating space and avoids issues such as false soldering or solder burrs falling off.

[0051] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
