Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a relay base and a reed switch relay. Background Art

[0002] As a commonly used control component, relays can use smaller currents to control larger currents, use low voltages to control high voltages, use direct currents to control alternating currents, and can isolate control circuits from controlled circuits. They are widely used in automatic control, remote control, and protection circuits. Traditional electromagnetic relays are electrical relays that work by using the suction force generated between the electromagnet core and the armature in the input circuit. This type of relay is large in size, slow in action, and has limited reliability and life. As electronic appliances develop towards miniaturization and micro-miniaturization, new requirements are put forward for relays. By placing the reed switch in the coil, the reed relay, as a new type of relay, can meet the needs of this development in many aspects.

[0003] The interior of the reed switch is composed of a pair of elastic magnetic reeds made of magnetic materials. The magnetic reeds are sealed in a glass tube filled with inert gas. The end faces of the magnetic reeds overlap, but a thin gap is left. The end contacts of the magnetic reeds are plated with a layer of precious metal rhodium or ruthenium to stabilize the switch performance and extend the service life. When there is no magnetic field, the two reeds in the glass tube are separated. When a magnetic substance approaches the glass tube, under the action of the magnetic field lines, the two reeds in the tube are magnetized and attract each other to contact, so that the circuit connected to the two pins is connected. After the external magnetic force disappears, the two reeds separate due to their own elasticity, and the circuit is disconnected.

[0004] In the prior art, if the relay is directly connected to the external wires, the line layout will be chaotic and disordered. Especially when multi-way relays are used in electrical equipment such as electrical cabinets, the wiring workload will be huge, because each line must be accurately connected to the corresponding endpoint, which not only makes the lines inside the electrical cabinet a complicated "line maze", but also greatly increases the difficulty and time of installation, debugging and maintenance.

[0033] Embodiment 1:

[0034] like Figures 1 to 4 As shown, a relay base includes: a base body 1, on which a channel 100 is arranged, and the upper end of the channel 100 passes through the base body 1 to form an insertion port 10, so that the relay can be easily inserted into the base.

[0035] The main circuit board 2 is arranged in the base body 1 and is located below the channel 100. The integrated layout optimizes space utilization.

[0036] The first conductive plug 3 is arranged in the channel 100 along the direction of the channel 100, and a plug interface 31 is formed at its upper end, and its lower end is connected to the main circuit board 2. The direct connection between the first conductive plug 3 and the main circuit board 2 can reduce the use of connectors, thereby reducing the possibility of poor contact and improving the reliability of the relay base; the plug interface 31 is located in the channel 100 to reduce the risk of damage caused by environmental factors such as dust, moisture, etc.

[0037] The terminal block 4 is used for external circuits, which is connected to the main circuit board 2 and is connected to the first conductive plug 3 through the printed circuit on the main circuit board 2; wherein, the number of the first conductive plugs 3 is adapted and designed according to the number of matching relay plugs, and the channel 100 can be regarded as a cavity for installing the first conductive plug 3. In this embodiment, the number of channels 100 is not less than the number of the first conductive plugs 3, and the channels 100 can be connected or not connected; by arranging the first conductive plug 3 on the main circuit board 2 to form a plug interface 31, it is convenient to quickly plug in the relay, and at the same time, the printed circuit on the main circuit board 2 makes the first conductive plug 3 electrically connected to the terminal block 4, avoiding the need for routing and wiring in the base, and the external wires are gathered on the terminal block 4, so that the line layout is neat and orderly, and the difficulty and time of installation, debugging and maintenance are greatly reduced.

[0038] The first conductive plug 3 includes a first sheet body portion 300, the lower end of the first sheet body portion 300 is plugged into the main circuit board 2, one side of the first sheet body portion 300 is bent to form a second sheet body portion 301, the upper ends of the first sheet body portion 300 and the second sheet body portion 301 form the plug interface 31, the upper side of the plug interface 31 is provided with a guide port 32, which can guide the pin or the corresponding connecting device to smoothly enter the plug interface 31, and the lower side is provided with a protrusion 33, which can prevent misoperation during plugging and unplugging, on the one hand to improve the strength of the first conductive plug 3, on the other hand to provide a certain feedback force for the plugging and unplugging operation.

[0039] A constricted portion 101 is provided at the lower end of the channel 100, and the constricted portion 101 can prevent the second sheet portion 301 of the first conductive plug 3 from passing through. An arc portion 102 is provided on the inner wall of the constricted portion 101 toward the first sheet portion 300. An elastic plate portion 302 is provided on the upper side of the first sheet portion 300 relative to the constricted portion 101. The lower side of the elastic plate portion 302 is connected to the first sheet portion 300, and the upper side thereof is inclined toward the arc portion 102.

[0040] The upper end of the channel 100 is provided with a flared portion 103, and the maximum width of the guide opening 32 is greater than the width of the flared portion 103 in the opening direction, so that the guide opening 32 can also be located in the channel 100, and the first conductive plug 3 can be prevented from transitioning toward the main circuit board 2 during the plugging and unplugging action. Combined with the above-mentioned elastic plate portion 302, double protection is formed for the main circuit board 2.

[0041] Both ends of the base body 1 are hinged with fixing buckles 5. The fixing buckles 5 are deformable, that is, they are made of plastic material or metal material of small thickness. They are used to fix the relay on the relay base and accommodate the relay through a certain elastic deformation, so that the installation process is fast and does not require additional tools.

[0046] The pressure plate portion 51 is in contact with the housing 6 of the relay. Both ends of the housing 6 are provided with positioning holes 61 for inserting the positioning protrusions 52, thereby improving the stability of the reed switch relay and the relay base after being plugged in and the reliability of the electrical connection.
