Embodiment 1

[0019] Please refer to FIG. 1, this embodiment provides a replaceable quick connector, which is composed of a connector board 1, a sealing ring 5, a circuit board 3, a connector base 2 and a locking nut 4. In combination with FIG. 2 for continuous description, a top surface of the above connector board 1 is connected to an inductive switch, a bottom center of the connector board 1 extends downwards to form a plugging column 6, limiting columns 14 are disposed at a bottom of the plugging column 6, two limiting columns 14 are preferred and disposed in relative to 180 degrees, a plurality of inductive domes 15 are disposed at one sides of the two limiting columns 14, four inductive domes 15 are preferred and lined up, clamping blocks 7 are disposed on an outer wall of the plugging column 6, clamping convex points 8 are disposed at upper parts of the clamping blocks 7, two clamping blocks 7 are preferred and disposed in relative to 180 degrees, and the clamping blocks 7 and the limiting columns 14 are not on the same straight line. In combination with FIG. 3 for continuous description, the connector base 2 is cylindrical, an interior of the connector base 2 is hollow, threads are disposed on an outer wall of the connector base 2, a dome 18 is respectively disposed at two sides of the outer wall, a lug boss 19 is disposed inside the dome 18, a clamping sheet 9 is disposed at a top of the connector base 2, a plugging hole 10 is formed in a center of the clamping sheet 9, the plugging hole 10 extends inwards to form two arc-shaped clamping bases 11, clamping slots 12 are disposed at one sides of the clamping bases 11, clamping concave points 13 are disposed in the clamping slots 12, and the clamping bases 11 are arranged in relative to 180 degrees. The circuit board 3 is installed in the connector base 2 through mutual cooperation of the clamping bases 11 and the lug boss 19, inductive contacts 16 corresponding to the inductive domes 15 the limiting slots 17 corresponding to the limiting columns 14 are disposed on the circuit board 3, the inductive contacts 16 are located in a middle of the circuit board 3, and two groups of inductive contacts 16 are provided.

[0020] During use, the connector base 2 is fixed on a device and locked through the locking nut 4, and then the limiting columns 14 of the connector board 1 are aligned to the limiting slots 17 so that the plugging column 6 is inserted into the plugging hole 10; the connector board 1 is rotated, so that the clamping blocks 7 on the connector board 1 enter into the clamping slots 12, the clamping blocks 7 and the clamping convex points 8 fit with the clamping concave points 13 so that the clamping blocks 7 are fixed in the clamping slots 12, at the same time the limiting columns 14 drives the circuit board 3 to rotate for fine adjustment, so that the inductive domes 15 just contact with one group of inductive contacts 16 on the circuit board 3, and the circuit is conducted; and the sealing ring 5 is clamped between the connector board 1 and the connector base 2 as well as between the connector base 2 and the locking nut 4 for sealing the quick connector.

[0021] Through the above structure design, the connection for the connector board and the connector base is more compact, the installation is quicker and more convenient, at the same time the inductive domes can contact with the inductive contacts on the circuit board accurately through the cooperation of the limiting columns and the limiting slots, so as to avoid a situation that the inductive domes and the inductive contacts cannot be contacted and conducted.

[0022] The above is the only preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Those skilled in the art may make various modifications and variations. Any modifications, equivalent replacements, improvements and the like made within the spirit and principle of the present disclosure shall fall within the scope of protection of the present disclosure.
