Description

Technical Field

[0001] This application relates to the field of indoor detection technology. Specifically, it relates to a detector mounting base and a detector. Background Art

[0002] Currently, detector mounting bases all use a one-terminal method, that is, the positive terminal uses a one-terminal and the negative terminal uses a one-terminal. When wiring is required, different numbers of wires are stuffed according to the wiring needs, and the screw pressure plate is tightened. Because the position for accommodating wires in a one-terminal is limited, when the number of stuffed wires is large, it may cause the one-terminal to be unable to tightly press the multiple stuffed wires, easily resulting in the wires stuffed into the one-terminal falling off from the detector mounting base. Utility Model Content

[0003] To solve the above problems, the purpose of the embodiments of this application is to provide a detector mounting base and a detector.

[0004] In a first aspect, an embodiment of this application provides a detector mounting base, including: a mounting base body and a terminal module;

[0021] Currently, the detector mounting base uses a one-terminal method, that is, the positive electrode uses one terminal and the negative electrode uses one terminal. When wiring is required, different numbers of wires are inserted according to the wiring needs, and the screw pressure plate is tightened. Since the position for the one-terminal to accommodate wires is limited, when the number of inserted wires is large, it may cause the one-terminal to be unable to tightly press the inserted multiple wires, easily resulting in the wires inserted into the one-terminal falling off from the detector mounting base.

[0022] Based on this, the following embodiments of the present application propose a detector mounting base and a detector. A wiring hole is provided in the middle of the mounting base body of the detector mounting base.

The terminal module can be respectively crimped in the positive terminal slot and the negative terminal slot. Among them, the positive terminal slot has two screw holes, and the negative terminal slot has three screw holes, so that two one-bit terminals can be simultaneously pressed and installed in the positive terminal slot and the negative terminal slot, two two-bit terminals can be simultaneously pressed and installed in the positive terminal slot and the negative terminal slot, or two two-bit terminals and an extension terminal can be simultaneously pressed and installed in the positive terminal slot and the negative terminal slot to form a combination of two terminals and a three-bit terminal. Of course, different terminals can also be arbitrarily combined and pressed according to the terminal slots of the positive terminal slot and the negative terminal slot, so as to avoid the defect that the wires inserted into the one-bit terminal are likely to fall off from the detector mounting base due to the compression and insertion of multiple wires into the terminal slot of the one-bit terminal, and has the advantage of reliable wiring.

[0023] Before describing the following embodiments, the following situations are explained first:

[0024] The terminal where the wire is crimped in the positive terminal slot is the positive extreme of the wire; the terminal where the wire is crimped in the negative terminal slot is the negative extreme of the wire.
