Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1, the coaxial cable F-head insertion tester comprises a base 1, a guide rail 2, a bracket 3, a dynamometer 4, a lifting mechanism, a positioning sleeve 5 and a pressing sleeve 6.
The guide rail is vertically fixed on the base, the support is vertically slidably positioned on the guide rail through a sliding block (omitted in the figure), the dynamometer is fixed at the front end of the support (the rear end of the support is fixed with the sliding block), and the lifting mechanism is used for driving the support to slide up and down along the guide rail.
The lifting mechanism (omitted in the figure) comprises a motor and a screw rod assembly, and the screw rod assembly is used for transmitting power of the motor to drive the support to move up and down. The lifting mechanism is also provided with an operating button (omitted from the figure).
The base is fixed with a supporting seat 13, a bolt 14 is arranged on the supporting seat, the positioning sleeve can be inserted on the bolt, a jack 15 matched with the bolt is arranged at the bottom of the positioning sleeve, the coaxial cable 20 is downwards inserted into the positioning sleeve, the coaxial cable needs to be kept at a certain length so that the upper part of the coaxial cable extends out of the positioning sleeve, and the inner diameter of the positioning sleeve is matched with the outer diameter of the coaxial cable.
The pressure cover is fixed in the bottom of the test head 4.1 of dynamometer bottom, presses the cover inner chamber to be equipped with rubber ring 16 in order to guarantee that F head after filling in can block and can not drop in pressing the cover.
The pressing sleeve and the positioning sleeve are correspondingly arranged up and down, the lifting mechanism drives the pressing sleeve to move downwards so that the coaxial cable is inserted into the F head, and the dynamometer measures the pressure in the process at the same time, so that whether the resistance in the F head installation process meets the standard is judged.
The above components are all of the prior art.
The application method of the utility model is as follows:
1. cutting a length of coaxial cable 20 as desired;
2. as shown in fig. 5, the sheath, the shielding layer and the foaming layer of the coaxial cable are pulled out by using a wire stripper, and the copper core 21 in the middle is exposed;
3. marking 22 the jacket surface of the coaxial cable with a marker, wherein the distance L between the marker and the end part (excluding the copper core) of the coaxial cable is the depth of the coaxial cable fully inserted into the F head;
3. as shown in fig. 3 and 4, the coaxial cable is inserted into the positioning sleeve, one end of the copper core needs to be exposed out of the positioning sleeve for a certain length to ensure that the positioning sleeve is not blocked when the F-head is installed (the mark is positioned above the positioning sleeve), the positioning sleeve is inserted on the supporting seat, and the F-head is plugged into the pressing sleeve;
5. starting a dynamometer, starting a lifting mechanism, enabling the F head to move downwards, gradually inserting the coaxial cable into the F head, and stopping the lifting mechanism when the pressing sleeve descends to the marking position;
6. the maximum value displayed by the load cell is recorded as the maximum resistance experienced during installation of the F-head.
In the actual operation process, as the part of the coaxial cable exposed out of the positioning sleeve is not supported by the positioning sleeve, when the pressing sleeve applies downward pressure, the part of the coaxial cable is easy to swing and twist, so that the F head cannot be accurately butted with the coaxial cable, detection failure is caused, and data acquisition is influenced, therefore, the positioning sleeve is improved as follows:
as shown in fig. 7 and 8, the positioning sleeve comprises a bottom post 7, a guide rod 8, a sliding sleeve 9 and a spring 10. The bottom of the bottom column is provided with a jack 15 matched with the bolt, the guide rod is vertically fixed on the bottom column, the sliding sleeve can be vertically and slidably positioned on the guide rod, the spring is sleeved on the guide rod in a penetrating manner and used for pushing the sliding sleeve upwards, the sliding sleeve is provided with an observation groove 12 which vertically extends, and the inner diameter of the sliding sleeve is matched with the outer diameter of the coaxial cable.
And a limiting structure (omitted in the figure), such as a limiting groove and a limiting pin, is further arranged between the sliding sleeve and the guide rod and used for controlling the sliding stroke of the sliding sleeve.
When the detection starts, the sliding sleeve can completely wrap the periphery of the coaxial cable, when the pressing sleeve drives the F head to downwards press, the pressing sleeve or the F head pushes the sliding sleeve to downwards move (the coaxial cable is not moved), the downward moving position of the F head is checked through the observation groove to ensure that the coaxial cable is completely inserted in place, no gap exists between the pressing sleeve (or the F head) and the sliding sleeve in the whole process, the coaxial cable cannot swing and twist, and therefore the coaxial cable can be smoothly butted with the F head, and detection failure is avoided. When the pressing sleeve rises, the sliding sleeve also rises synchronously.
Preferred embodiments of the present utility model are shown in the drawings. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
