Description

Technical Field

[0001] This utility model relates to the field of relay protection technology, and in particular to a reed relay with a protective structure. Background Technology

[0002] A reed relay is a new type of sealed contact relay that uses a reed made of iron-nickel alloy as its contact. It features fast action, high sensitivity, stability, reliability, and low power consumption. Its contacts have no mechanical contact, eliminating wear and contact resistance issues, and it is widely used in automatic control, communication equipment, and power systems.

[0003] Currently, the pins on reed relays are generally exposed, making them susceptible to external forces such as bending or breakage, which results in certain deficiencies in safety and reliability. Optimization and improvement are needed to address this issue. Utility Model Content

The lower end of the relay body has a horizontally arranged protective plate, and the upper end of the protective plate has an opening corresponding to the pins. The lower ends of the pins slide into the openings. Connecting plates are fixedly connected to both ends of the relay body. A sliding groove is provided within the connecting plate, and a slider is slidably connected to the inner wall of the groove. A slot is provided on the side of the slider away from the relay body. A horizontally arranged locking rod is inserted into the connecting plate near its top on the side away from the relay body. The locking rod is threadedly connected to the connecting plate. A knob is fixedly connected to the end of the locking rod away from the connecting plate, and one end of the locking rod passes through the connecting plate and extends into the sliding groove. A spring is fixedly connected between the slider and the top of the sliding groove. A support rod is fixedly connected to the lower end of the slider, and the lower end of the support rod slides through the connecting plate and is fixedly connected to the upper end of the protective plate.

[0007] Preferably, both the upper and lower ends of the support rod are fixedly fitted with fixing rings, and the opposite sides of the two fixing rings are respectively fixedly connected to the lower end of the slider and the upper end of the protective plate.

[0008] Preferably, the outer side wall of the slider is provided with an arc-shaped groove, and a ball is rotatably connected to the inner side wall of the arc-shaped groove, with part of the ball passing through the arc-shaped groove.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3A reed relay with a protective structure includes a relay body 1 and multiple pins fixed at its lower end. The lower end of the relay body 1 is provided with a horizontally arranged protective plate 2 for external protection of the pins. The upper end of the protective plate 2 is provided with an opening corresponding to the pins. The lower end of the pins slides into the opening. A first rubber pad 3 is fixedly connected to the inner wall of the opening to prevent the pins from being worn. A second rubber pad 4 is fixedly connected to the upper end of the protective plate 2 to prevent wear between the upper end of the protective plate 2 and the lower end of the relay body 1.

[0020] In this embodiment, connecting plates 7 are fixedly connected to both the left and right ends of the relay body 1 for mounting and accommodating sliders 6. The connecting plate 7 has a sliding groove, and sliders 6 are slidably connected to the inner side wall of the sliding groove for supporting the support rod 5. An arc-shaped groove is provided on the outer side wall of the slider 6, and a ball bearing 11 is rolled on the inner side wall of the arc-shaped groove to reduce the resistance when the slider 6 moves. Part of the ball bearing 11 passes through the arc-shaped groove.

[0021] In this embodiment, the slider 6 has a slot on the side away from the relay body 1 to accommodate the locking rod 12. The connecting plate 7 has a horizontally arranged locking rod 12 inserted on the side away from the relay body 1 and near its top to lock the slider 6 in place with the slot. The locking rod 12 and the connecting plate 7 are connected by a thread. A knob 13 is fixedly connected to the end of the locking rod 12 away from the connecting plate 7 to drive the locking rod 12 to rotate. A rubber strip 14 is fixedly connected to the surface of the knob 13 to prevent slipping when rotating the knob 13. One end of the locking rod 12 passes through the connecting plate 7 and extends into the groove.

[0022] In this embodiment, a spring 8 is fixedly connected between the slider 6 and the top of the groove to provide elastic support for the slider 6. A support rod 5 is fixedly connected to the lower end of the slider 6 to support the protective plate 2. The lower end of the support rod 5 slides through the connecting plate 7 and is fixedly connected to the upper end of the protective plate 2. Fixing rings 9 are fixedly sleeved at both the upper and lower ends of the support rod 5 to improve the firmness of the two ends of the support rod 5. The opposite sides of the two fixing rings 9 are fixedly connected to the lower end of the slider 6 and the upper end of the protective plate 2, respectively.

[0023] In this embodiment, firstly, the protective plate 2 provides external protection for the pins of the relay body 1, effectively preventing them from breaking or bending due to external forces. When soldering and inserting the pins, simply push the protective plate 2 upward so that its upper end fits tightly against the lower end of the relay body 1, thus avoiding obstruction of the pins. As the protective plate 2 rises, the support rod 5 and the slider 6 will rise together until the slider 6 moves to the top of the groove. At this time, the locking rod 12 is driven to rotate by manually rotating the knob 13. The locking rod 12 is screwed into the groove using the thread engagement principle, locking the position of the slider 6. When the relay body 1 is removed for maintenance or repair, the locking rod 12 is manually unscrewed from the groove. The spring 8 then uses its elasticity to push the slider 6 down to reset, and then the support rod 5 drives the protective plate 2 down to reset, so that the protective plate 2 can once again provide effective protection for the pins.

[0024] As described above, the relay body and pins are existing mature technologies, and their working principle and internal structure are known to those skilled in the art. This application only utilizes its function and does not improve its internal structure, therefore, it will not be described in detail.

[0025] 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 within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
