Problems solved by technology

In the existing large-scale isolator, since the resistor is away from the isolator shell, the resistor can dissipate part of the heat through natural radiation, but it still cannot achieve rapid cooling of the resistor
However, in order to solve the problem of the large space occupied by the existing isolator, when the size of other components remains unchanged, reducing the overall volume of the isolator will inevitably hinder the heat dissipation of the resistor, which is contradictory

Abstract

The invention belongs to the technical field of ferrite isolators, and relates to a resistor hidden type large isolator which comprises an installation shell with an inner cavity formed in the front face, an internal assembly is arranged in the inner cavity, the internal assembly comprises a center conductor, and notches for avoiding resistor connecting pins are formed in the front face of the installation shell. A covered channel structure is arranged in the inner wall or the outer wall of the front face of the installation shell, and a resistor installation assembly is installed in the covered channel structure. The resistor installation assembly comprises a resistor. According to the isolator, the side wall of the installation shell is provided with the covered channel structure, the resistor is installed in the covered channel structure, a base for installing the resistor is omitted, and compared with an existing isolator, the whole isolator occupies smaller area for installation.Meanwhile, the resistor is installed in the covered channel structure, and the contact area of the resistor and the installation shell is increased, so that heat generated by the resistor is rapidly transferred, and the heat dissipation efficiency of the resistor is improved.

Description

technical field [0001] The invention belongs to the technical field of ferrite isolators, in particular to a large-scale isolator with hidden resistance. Background technique [0002] The bottom of the existing ferrite isolator is equipped with a base for welding resistors. The function of this base is only for welding resistors, and the base causes the bottom surface of the shell to become larger, so that the circuit board or module cavity occupied by the isolator is installed body area increases. Especially for larger isolators, the size of the resistor used is large, and the base should be correspondingly larger, which makes the problem of large installation area more prominent. At the same time, since the resistor on the isolator generates heat during operation, in order to ensure the normal operation of the isolator, the heat dissipation of the resistor is also extremely important. In the existing large-scale isolator, since the resistor is away from the isolator hous...
