[0002] Coaxial cable is a kind of wire and signal transmission line, which is composed of inner conductor, insulation layer, outer conductor and sheath from inside to outside. In the production process of coaxial cable, it is necessary to test the coaxial cable to ensure the pass rate of the coaxial cable. In the test process, the coaxial cable needs to be connected through a connecting device. For this reason, we need to provide a connecting device for coaxial cable testing.

[0003] At present, the connector used for testing coaxial cable products includes two parts: a rear body and a front body. During the test, the rear body is first inserted into the end of the coaxial cable and stuck at the outer wave peaks and troughs. Then the front body is rotated on the rear body, and the test connector as a whole is firmly stuck on the coaxial cable. After the test is completed, the front body is rotated again to take out the rear body. In this way, during each coaxial cable test, the rear body needs to be repeatedly nested and the front body rotated. The operation process is relatively cumbersome, which greatly affects the test efficiency of the coaxial cable. Utility Model Content

Therefore, during the coaxial cable connection process, the coaxial cable to be connected is placed on the mounting block 2, and the position of the connecting seat 3 is adjusted through the mutual cooperation of the slider 501, the connecting rod 502, the rack 503, the first spring pin 504 and the rack 503 matching parts, so that the test head 4 is connected to the coaxial cable, and the coaxial cable connection operation can be realized. Compared with the connection method of inserting the front body and then rotating the front body into the connection method, this connection method has a simple structure and is easy to operate. It can simplify the connection steps of the coaxial cable test, shorten the assembly time when the coaxial cable is connected, and speed up the connection efficiency of the coaxial cable, thereby improving the testing efficiency of the coaxial cable, and then improving the production efficiency of the coaxial cable.

[0034] Specifically, the assembly time when the coaxial cable is connected can be shortened, and the disassembly time after the coaxial cable is connected can also be shortened.

[0035] In this embodiment, the test head 4 includes: a test head body 401, a first test part 402, a second test part 403 and a limit groove 404. The test head body 401 is located in the connection seat 3, and one end of the test head body 401 close to the mounting block 2 extends to the outside of the connection seat 3. The first test part 402 is installed on the end surface of the test head body 401 close to the mounting block 2, the second test part 403 is sleeved on the test head body 401, and the second test part 403 is located outside the connection seat 3. The limit groove 404 is opened on the outer peripheral surface of the test head body 401, and the limit groove 404 is located inside the connection seat 3. Therefore, the first test part 402 is connected to the inner conductor of the coaxial cable for testing the inner conductor of the coaxial cable; the second test part 403 is connected to the outer conductor of the coaxial cable for testing the outer conductor of the coaxial cable.

[0036] In this embodiment, the connection base 3 is provided with a first through hole 301 and a second through hole 302, the connection base 3 is provided with a second spring pin 303, the first through hole 301 is connected with the second through hole 302, the test head body 401 is located in the first through hole 301, the second spring pin 303 passes through the second through hole 302, and is slidably connected with the connection base 3, and the second spring pin 303 is matched and connected with the limiting groove 404. Therefore, through the mutual cooperation of the second spring pin 303 and the limiting groove 404, the installation and removal of the test head 4 can be realized.

[0037] In this embodiment, the first spring pin 504 includes: a pin shaft 5041, a fixing sheet 5042 and a spring 5043. The fixing sheet 5042 and the spring 5043 are both sleeved on the pin shaft 5041, and the fixing sheet 5042 is connected to the pin shaft 5041. The spring 5043 is located above the fixing sheet 5042 and is connected to the fixing sheet 5042. Therefore, since the spring 5043 has a certain telescopic function, it is convenient to adjust the position of the connecting seat 3.

[0038] Specifically, under normal conditions (i.e., when the connecting seat 3 does not move), the spring 5043 is in a normal state, and the rack 503 matching piece cooperates with the rack 503. At this time, under the constraint of the rack 503, the connecting seat 3 cannot move. During adjustment (i.e., during the movement of the connecting seat 3), the pin shaft 5041 is pulled upward. At this time, the spring 5043 is in a compressed state, and the rack 503 matching piece is disengaged from the rack 503. The rack 503 no longer constrains the first spring pin 504, and the slider 501 can be moved to adjust the position of the connecting seat 3. During the movement of the connecting seat 3, it is only necessary to pull the pin shaft 5041 upward. After the adjustment is completed, the pin shaft 5041 is released, and the spring 5043 in the compressed state automatically moves downward due to the restoration of the compressed state, so that the rack 503 matching piece moves downward and abuts against the rack 503, thereby realizing the adjustment of the position of the connecting seat 3. The structure is simple and easy to operate, which can shorten the time for adjusting the position of the connecting seat 3 and further improve the connection efficiency of the coaxial cable.

[0039] In this embodiment, two connecting rods 502 are provided, and the two connecting rods 502 penetrate the slider 501 from both sides of the slider 501 respectively, a plurality of first spring pins 504 are provided, and a plurality of rack matching pieces 505 are provided; wherein: the number of the first spring pins 504 is equal to the number of the rack matching pieces 505. Thus, the plurality of first spring pins 504 can ensure that the connection seat 3 remains stable, and during the test process of the coaxial cable, the test head 4 always remains stable without shaking, and can ensure that the test work of the coaxial cable is carried out normally.

[0040] In this embodiment, a first arc groove 201 is provided on a side of the mounting block 2 away from the base 1, a plurality of second arc grooves 202 are provided in the first arc groove 201, and a plurality of arc protrusions 203 are provided in the first arc groove 201; wherein, the number of the second arc grooves 202 is equal to the number of the arc protrusions 203, and the second arc grooves 202 and the arc protrusions 203 are arranged alternately. Thus, the second arc groove 202 corresponds to the crest of the coaxial cable, and the arc protrusion 203 corresponds to the trough of the coaxial cable. During the connection process of the coaxial cable, the crest of the coaxial cable is inserted into the second arc groove 202, and the arc protrusion 203 is inserted into the trough of the coaxial cable, ensuring that the coaxial cable is stably placed in the first arc groove 201, and will not move relative to the mounting block 2, further ensuring the stability of the coaxial cable connection.

[0041] In this embodiment, a clamping block 6 is provided above the test head 4, the clamping block 6 is connected to the connection seat 3, and the side of the clamping block 6 close to the mounting block 2 is a guide slope 601. Therefore, during the test process of the coaxial cable, the guide slope 601 can ensure that the coaxial cable is firmly clamped in the first arc groove 201, further improving the connection effect of the coaxial cable.

[0042] In this embodiment, the first spring pin 504 has the same structure as the second spring pin 303. Specifically, in a normal state (i.e., the test head 4 is installed on the connection seat 3), the spring 5043 is in a normal state, and the pin shaft 5041 is inserted into the limiting groove 404. At this time, under the constraint of the pin shaft 5041, the test head 4 is installed on the connection seat 3. When installing and removing, the pin shaft 5041 is pulled upward to make the pin shaft 5041 disengage from the limiting groove 404. At this time, the pin shaft 5041 cannot constrain the test head 4, and the test head 4 can be moved, so that the installation and removal of the test head 4 can be achieved.

[0043] The connection process of the coaxial cable of the utility model is as follows: first, the connection seat 3 is controlled to move to a side away from the mounting block 2 by the connection mechanism 5, so as to ensure that there is enough space between the mounting block 2 and the connection seat 3 to accommodate the coaxial cable to be tested;

[0044] Next, the coaxial cable to be tested is placed in the first arc-shaped groove 201, and the crest of the coaxial cable is inserted into the second arc-shaped groove 202, and the arc-shaped protrusion 203 is inserted into the trough of the coaxial cable;

[0045] Finally, the connecting seat 3 is controlled to move toward the side close to the mounting block 2 through the connecting mechanism 5, so that the first testing part 402 contacts the inner conductor of the coaxial cable, and the inner conductor of the coaxial cable is tested through the first testing part 402, and the second testing part 403 contacts the outer conductor of the coaxial cable, and the outer conductor of the coaxial cable is tested through the second testing part 403.

[0046] To sum up, during the coaxial cable connection process of the utility model, the coaxial cable to be connected is placed on the mounting block 2, and the position of the connecting seat 3 is adjusted through the mutual cooperation of the slider 501, the connecting rod 502, the rack 503, the first spring pin 504 and the matching parts of the rack 503, so that the test head 4 is connected to the coaxial cable, and the coaxial cable connection operation can be realized. Compared with the connection method of inserting the front body and then rotating and inserting the front body, the connection method has a simple structure and is easy to operate. It can simplify the connection steps of the coaxial cable test, shorten the assembly time when the coaxial cable is connected, and speed up the connection efficiency of the coaxial cable, thereby improving the testing efficiency of the coaxial cable, and then improving the production efficiency of the coaxial cable.

[0047] The above description is based on the ideal embodiment of the utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical concept of the utility model.
