[0002] Infrared detectors are devices that convert incident infrared radiation signals into electrical signal outputs. Infrared radiation is an electromagnetic wave with a wavelength between visible light and microwaves, which is imperceptible to the human eye. The spectral response of the detector extends from short waves to long waves; the detector has developed from a single unit to a multiple unit, from a multiple unit to a focal plane, and a wide variety of detectors and systems have been developed, from single-band detection to multi-band detection, and from refrigerated detectors to room temperature detectors. The infrared detector interface includes a terminal block, on which there are a positive electrode interface, a negative electrode interface, two signal interfaces and two anti-disassembly interfaces. The positive electrode interface, the negative electrode interface, the two signal interfaces and the two anti-disassembly interfaces are all equipped with screws to limit the position of the wires. During the assembly process, the screws on the positive electrode interface, the negative electrode interface, the two signal interfaces and the two anti-disassembly interfaces need to be tightened one by one. This method takes a lot of time and affects the assembly efficiency. Therefore, it is necessary to design an infrared detector interface that improves the assembly efficiency. Utility Model Content
[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an infrared detector interface to solve the problems raised in the above-mentioned background technology. The utility model can use a clamping screw to clamp and limit the wires in the positive interface, the negative interface, the two signal interfaces and the two anti-dismantling interfaces, thereby improving assembly efficiency.
[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an infrared detector interface, including a terminal block, the front side of the terminal block is processed with a positive interface, a negative interface, two signal interfaces and two anti-disassembly interfaces from left to right in sequence, the upper surface of the terminal block is provided with six through holes which are respectively connected to the positive interface, the negative interface, the two signal interfaces and the two anti-disassembly interfaces, an insulating strip is provided on the upper side of the terminal block, and six pressure columns which match the through holes are evenly installed on the lower surface of the insulating strip, and the pressure columns are inserted in the through holes, a circular hole is provided in the middle position of the upper surface of the insulating strip, a clamping screw is inserted in the circular hole, and the lower end of the clamping screw is threadedly connected in a threaded barrel, and the threaded barrel is connected and fixed to the terminal block.
[0005] Furthermore, a vertical hole is opened on the upper surface of the terminal block, the threaded barrel is installed in the vertical hole, and the upper end of the threaded barrel is flush with the upper end of the terminal block.
[0006] Furthermore, the lower surface of the terminal block seat is recessed upward to form a hexagonal hole, the hexagonal hole is communicated with the vertical hole, and a hexagonal body is connected and fixed to the lower end of the threaded tube, and the hexagonal body is installed in the hexagonal hole.
[0007] Furthermore, both ends of the terminal block are connected with connecting plates through connectors, and a fixing hole for inserting a screw is provided in the middle of the upper surface of the connecting plate.
[0008] Furthermore, the connector includes a plate, two plates are connected and fixed at the edge of one side of the upper surface of the connecting plate, the plate and the connecting plate are an integrally formed structure, the plate and the connecting plate are arranged perpendicular to each other, the plate is fitted with the terminal block, a plug is fixed on the side of the plate facing the terminal block, a socket is provided in the area of the terminal block covered by the plate, and the plug is inserted into the socket.
[0009] Furthermore, a blind hole is provided at the position where the pressure column is installed on the insulating strip, and the upper end of the pressure column is fixed in the blind hole.
[0010] Beneficial effects of the utility model:
[0011] 1. Pass the clamping screw through the round hole and screw it into the threaded barrel. Then, after inserting the wires into the positive interface, the negative interface, the two signal interfaces and the two anti-dismantling interfaces respectively, turn the clamping screw. The clamping screw squeezes the insulating strips. The insulating strips drive the pressure column to slide along the perforation until the lower end of the pressure column presses and holds the end of the wire. In this way, the wires in the positive interface, the negative interface, the two signal interfaces and the two anti-dismantling interfaces can be clamped and limited by one clamping screw, thereby improving assembly efficiency.
[0012] 2. The hexagonal body on the threaded barrel is installed in the inner hexagonal hole, so that the stability of the connection between the threaded barrel and the terminal block is improved under the cooperation of the hexagonal body and the inner hexagonal hole.
[0013] 3. Connecting plates are arranged on both sides of the terminal block, and the plugs on the plates are inserted into the sockets on the terminal block to realize the connection between the connecting plates and the terminal block. After the connecting plates are installed at the required positions with screws, the terminal block is limited. Since the connecting plates and the terminal block are in a plug-in relationship, the connecting plates and the terminal block can be stored separately. Compared with the method of integrally forming the connecting plates and the terminal block, the connecting plates can be prevented from being squeezed, deformed and damaged.
