The present disclosure relates to a quick connector.
An inductive switch is a component, which can turn on and turn off a circuit to realize switch functions by receiving an infrared ray released from the human body. Since the switch functions can be realized without touching the inductive switch directly, the inductive switch is more convenient to use; and therefore the inductive switch is widely applied in lamps, sliding doors, air conditioners and various devices. The interaction between the inductive switch and a device is mainly realized through a quick connector. At present, the quick connector on the market is mainly composed of a connector board and a connector base, a top surface of the connector board is connected to the inductive switch, a threaded column is disposed on a bottom surface of the connector board, an inductive pin is disposed at a bottom of the threaded column, a threaded hole is formed in the connector base, a circuit board is disposed in the threaded hole, an inductive contact is disposed on the circuit board, and after the connector board is in rotationally connected to the connector base through the cooperation of the threaded column and the threaded hole, the inductive pin contacts with the inductive contact mutually, and the circuit is conducted. The quick connector has the following two problems: first, in order to ensure the firm installation of the quick connector, the threaded column and the threaded hole are generally longer; during installation, the threaded column and the threaded columns need to be rotated for many times, so that the quick connector can be installed in place, which is time-consuming and force-consuming, and at the same time the longer threaded column and the threaded hole enable the whole quick connector to have a large volume, so as not to be applied in small devices. Second, after the quick connector is dismounted for many times, the circuit board is prone to deflection, causing the inductive pin incapable of aligning and contacting with the inductive contact on the circuit board, and the circuit cannot be conducted.
In view of defects of a quick connector of an existing inductive switch, the technical problem to be solved by the present disclosure is to provide a replaceable quick connector capable of installing a connector board and a connector base quickly; and at the same time, the fixation for a circuit board of the replaceable quick connector is more stable.
In order to implement the above purpose, according to one aspect of the present disclosure, the present disclosure is implemented by the following technical measures: a replaceable quick connector, including a connector board, a connector base, a circuit board and a locking nut, where a bottom center of the connector board extends downwards to form a plugging column, two clamping blocks are disposed on an outer wall of the plugging column, clamping convex points are formed in upper parts of the clamping blocks, the clamping blocks are arranged in relative to 180 degrees, a clamping sheet is disposed at a top of the connector base, a plugging hole for plugging the plugging column is formed in a center of the clamping sheet, the plugging hole extends inwards to form two clamping bases, the clamping bases are arranged in relative to 180 degrees, clamping slots for clamping the clamping blocks are disposed at one sides of the clamping bases, clamping concave points for clamping the clamping convex points are formed in the clamping slots, threads are disposed at outer walls of the clamping bases, and the locking nut is sleeved at the threads of the outer walls of the clamping bases.
Preferably, two limiting columns are disposed at a bottom of the plugging column, and the limiting columns and the clamping blocks are not on the same straight line.
Preferably, a plurality of inductive domes are disposed at one sides of the two limiting columns, and the inductive domes are lined up.
Preferably, inductive contacts corresponding to the inductive domes and limiting slots corresponding to the limiting columns are disposed on the circuit board.
Preferably, the inductive contacts are located in a middle of the circuit board, and two groups of inductive contacts are preferred.
Preferably, a sealing ring is disposed between the connector board and the connector base, as well as between the connector base and the locking nut.
Preferably, a dome is respectively disposed at two sides of an outer wall of each clamping base, a lug boss is disposed in each dome, and the circuit board is installed in the connector base through the mutual cooperation of the clamping bases and the lug boss. The fixation for the circuit board designed above is more stable.
Compared with the prior art, the present disclosure has the following advantages: 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.
