Description
Technical Field
The invention relates to a contact pin type lead connector for a test piece box, which is used for sealing a sensor wiring hole on the test piece box for a coal and gas outburst test.
Background
In the coal and gas outburst test process, various sensors such as a stress sensor, a temperature sensor, a pore pressure sensor, an acoustic emission probe and the like need to be buried in the test piece box, so that a sensor wiring hole needs to be formed in the side wall of the test piece box to ensure normal connection of the sensors and a data acquisition system. However, in the coal and gas burst test, it is necessary to fill the inside of the sample box with gas or carbon dioxide gas, and therefore the sample box must have good airtightness.
The existing test piece box has the influence on the air tightness of the test piece box after the through hole for connecting the sensor is formed on the side wall; or no holes are opened to ensure good air tightness, but data monitoring means during the test are limited.
Disclosure of Invention
The invention aims to provide a wire joint which is arranged in a sensor wiring hole on the side wall of a test piece box, can provide reliable connection for a sensor inside the test piece box and a data acquisition system outside the test piece box, and can ensure the air tightness of the test piece box in the test process.
Therefore, the technical scheme adopted by the invention is as follows: a contact pin type lead connector for a test piece box comprises a T-shaped circular truncated cone main body which is matched with a T-shaped sensor wiring hole of the test piece box and can be inserted into the T-shaped sensor wiring hole from inside to outside; a gasket and a sealing ring are sleeved on the small round table of the T-shaped round table main body and are pressed in the T-shaped sensor wiring hole by the step surface of the T-shaped round table main body; the middle part of "T" shape round platform main part is seted up two at least tube holes that link up, and every tube hole interpolation is equipped with an insulating lead tube, and outside the both ends that insulating lead tube and tube hole adopted the viscose fixed and insulating lead tube all extended the tube hole, a wire was equipped with in every insulating lead tube interpolation, and the both ends that wire and insulating lead tube adopted the viscose fixed and wire all extended outside the insulating lead tube, the medial extremity of wire is used for linking to each other with the connecting wire of the sensor of test piece incasement, and the outside end of wire is used for linking to each other with the connecting wire of the data acquisition device of test piece incasement.
Preferably, the number of the pipe holes is four, the pipe holes are uniformly distributed in a circumferential mode around the center of the T-shaped circular truncated cone main body, and the connection requirements of a plurality of sensors in the test piece box and a data acquisition device outside the test piece box can be met.
More preferably, the conducting wire is a copper wire.
More preferably, the inner end of the lead is connected with a connecting wire of the sensor in the test piece box by welding. The stability of connection is increased, and the disconnection of the connection part caused by the movement of pulverized coal or similar materials paved in the test piece box in the test process is avoided.
The invention has the beneficial effects that: the sensor wiring hole on the test piece box is effectively sealed through the T-shaped round platform main body, the gasket and the sealing ring, so that the integral air tightness of the test piece box is ensured, and the test piece box is simple in structure, small in size, light in weight, convenient to carry, convenient to mount and stable in connection; because the sensor wiring hole of test piece case also is the step form, in the experimentation, when test piece case internal pressure was greater than external atmospheric pressure, the outside effort was applyed to the contact pin formula wire to internal pressure, and the sealing washer will further closely knit the test piece box, and the binding face in the sensor wiring hole of "T" shape round platform main part and test piece case increases, makes whole bearing capacity promote, and the leakproofness reinforcing promotes the pressurize performance of test piece case.
