The invention provides a cable head. The cable head comprises a shell, two interfaces, a circuit board component and a support component, wherein the shell is in the shape of a hollow cylinder, the two interfaces are formed in the two ends of the shell respectively, and the circuit board component is arranged in the shell and electrically connected with the interfaces through signal transmission lines; the support component is arranged in the shell, the two interfaces are located at the two ends of the support component, the circuit board component is fixedly installed on the support component, and the interfaces and the circuit board component are relatively fixed through the support component. By arranging the support component, the structure of the circuit board component installed in the interfaces in the shell is more stable, the interfaces and the circuit board component are relatively fixed during installation or usage of the interfaces, so that deformation of the signal transmission lines connecting the interfaces with the circuit board component under the action of force is avoided, and normal realization of the electric signal transmission function of the signal transmission lines is guaranteed.
Description
technical field [0001] The invention relates to the field of geological exploration, in particular to a cable head. Background technique [0002] In the process of geological exploration, in order to seek the geological parameters of the subsurface strata section, geological detectors are often used to measure the geometric parameters of the wellbore and combined with the comprehensive geological parameters to judge the state of the underground structure in a certain area. The cable head is a special device for the connection between the logging cable and the geological detector, so as to realize the measurement signal transmission between the logging cable and the geological detector. [0003] The structure of the existing cable head mainly includes a hollow shell, end caps that movably close the two open ends of the shell, and two interfaces built in the shell, a PCB (Printed Circuit Board) circuit board and a plurality of signal transmission lines, wherein two The interf...
