Description

Technical Field

[0001] The utility model relates to the technical field of electric connector test tooling, in particular to a rain test pressing tooling for electric connectors. Background Art

[0002] Heavy-duty electric connectors for trains are used for power and signal transmission between cars such as subways, high-speed trains, and electric locomotives. In order to detect whether the sealing performance of the heavy-duty electric connectors produced after connection meets the design requirements, it is necessary to conduct a rain test on the outer shell of the electric connector. When the electric connector is connected, it is necessary to position the tooling to clamp the electric connector to simulate the compression state of the electric connector in actual use.

[0003] However, when the existing clamping tool is used for rain test, after the heavy-duty electrical connector is installed, due to the lack of positioning function, the long heavy-duty electrical connector will bend downward due to the wire body, resulting in misalignment of the fixed connection part and loose sealing, thus affecting the test results of the real sealing performance of the electrical connector. Utility Model Content

[0004] The utility model aims to provide a rain test clamping tool for an electric connector, so as to solve the problem that when the existing tool is used to position the housing of the electric connector, the position of the electric connection joint is easily wrong, thus affecting the test result.

[0005] In order to solve the above problems, the utility model adopts the following technical means:

[0006] An electric connector rain test pressing tool comprises a base and a plurality of positioning mechanisms arranged in sequence;

[0007] The positioning mechanism includes a first support beam and a second support beam respectively arranged on opposite sides of the base, a horizontal optical track is detachably installed between the first support beam and the second support beam, and a tightening nut is also installed on the first support beam and the second support beam. The tightening nut is installed next to the disassembly parts at both ends of the optical track, and the outer wall of the tightening nut and the optical track serve as a clamping gap of the electrical connector housing.

[0008] Preferably, the first support beam and the second support beam are both provided with a through hole for the optical rail to pass through, and the first support beam and the second support beam are respectively provided with an optical rail mounting seat coaxial with the through hole, and the side walls of the optical rail mounting seat are provided with tightening bolts for tightening the optical rail.

[0009] Furthermore, the through hole on the first support beam is coaxially arranged with the through hole on the second support beam.

[0010] Furthermore, the first support beam and the second support beam are both vertically arranged angle steels, and horizontal rib plates are installed at the corner positions of the first support beam and the second support beam. The rib plates are arranged above the optical rail and the tightening nut to block water.

[0011] Furthermore, the base includes a top plate and a support frame, and drainage holes are distributed on the top plate.

[0012] Furthermore, the support frame includes a mounting horizontal plate and a reinforcement vertical plate, the bottom ends of the first support beam and the second support beam are positioned and installed on the top surface of the mounting horizontal plate, the bottom sides of the first support beam and the second support beam are respectively supported by the reinforcement vertical plates, the reinforcement vertical plates are welded and fixed to the mounting horizontal plate, and the top plate is laid on the top surfaces of the mounting horizontal plate and the reinforcement vertical plates.

[0013] During use, the utility model has the following beneficial effects:

[0014] When installing the electrical connector, one end of the optical track is disassembled, and then the outer shells of the male and female ends of the electrical connector are sleeved on the optical track, and the two ends of the outer shell of the electrical connector are tightly buckled, so that the outer shells at both ends of the electrical connector are sleeved on the optical track as a whole, thereby ensuring that the outer shells at both ends of the electrical connector are always in a horizontal state during the test process, effectively avoiding the situation where the snap-on position is pulled by the two ends of the electrical connector due to the original parts at both ends of the electrical connector not being positioned after snapping, which affects the results of the rain test. Moreover, after the object to be tested is sleeved on the optical track, the two ends of the object to be tested extend to the two ends of the optical track and extend between the tightening nut and the optical track, so that the materials at both ends of the object to be tested are clamped by the tightening of the tightening nut to achieve positioning. It can effectively increase the fixing and docking efficiency of the electrical connector. It can avoid the flashing phenomenon around the connection position of the electrical connector shell caused by uneven force, which affects the sealing effect of the electrical connector.

[0023] Please refer to Figure 1As shown, an electrical connector rain test clamping tool comprises a base 1 and a plurality of positioning mechanisms arranged in sequence;

[0024] The positioning mechanism includes a first support beam 2 and a second support beam 3 respectively arranged on opposite sides of the base 1, a horizontal optical track 4 is detachably installed between the first support beam 2 and the second support beam 3, and a tightening nut 5 is also installed on the first support beam 2 and the second support beam 3. The tightening nut 5 is installed next to the disassembly parts at both ends of the optical track 4, and the outer wall of the tightening nut 5 and the optical track 4 serve as a clamping gap of the electrical connector housing.

[0025] In this way, when installing the electrical connector, one end of the optical track 4 is disassembled, and then the outer shells of the male and female ends of the electrical connector are sleeved on the optical track 4, and the two ends of the electrical connector outer shell are tightly buckled, so that the outer shells at both ends of the electrical connector are sleeved on the optical track 4 as a whole, thereby ensuring that the outer shells at both ends of the electrical connector are always in a horizontal state during the test process, effectively avoiding the situation where the snap-on position is pulled by the two ends of the electrical connector due to the original parts at both ends of the electrical connector not being positioned after the snap-on, thereby affecting the rain test results. Moreover, after the object to be tested is sleeved on the optical track 4, the two ends of the object to be tested extend to the two ends of the optical track 4, and extend between the tightening nut 5 and the optical track 4, so that the materials at both ends of the object to be tested are clamped by the tightening nut 5 to achieve positioning. It can effectively increase the fixing and docking efficiency of the electrical connector. It can avoid the flash seam phenomenon around the connection position caused by uneven force on the electrical connector outer shell, which affects the sealing effect of the electrical connector.

[0026] Furthermore, the first support beam 2 and the second support beam 3 are both provided with a through hole 6 for the optical rail 4 to pass through, and the first support beam 2 and the second support beam 3 are respectively provided with an optical rail mounting seat 7 coaxial with the through hole 6, and the side wall of the optical rail mounting seat 7 is provided with a tightening bolt 8, and the tightening bolt 8 is used to tighten the optical rail 4.

[0027] Specifically, the aforementioned through hole 6 is used to pass the optical track 4, and when the tightening bolt 8 is loosened, the optical track 4 can move back and forth freely in the through hole 6. When one end of the optical track 4 is out of the through hole 6, the disassembly of the optical track 4 is completed.

[0028] In order to ensure that the optical track 4 is in a horizontal state, the through hole 6 on the first support beam 2 and the through hole 6 on the second support beam 3 are coaxially arranged.

[0029] Furthermore, the first support beam 2 and the second support beam 3 are both vertically arranged angle steels, and horizontal rib plates 9 are installed at the corner positions of the first support beam 2 and the second support beam 3. The rib plates 9 are arranged above the optical rail 4 and the tightening nut 5 to block water.

[0030] In this way, the rib plate 9 can not only reinforce the first support beam 2 and the second support beam 3, but also utilize the shielding effect of the rib plate 9 to prevent liquid from flowing into the unblocked positions at both ends of the material to be tested during the rain test, thereby reducing the impact on the detection structure of the connecting end of the electrical connector.

[0031] Furthermore, the base 1 includes a top plate 10 and a support frame 11 , and drainage holes 12 are distributed on the top plate 10 .

[0032] In addition, the support frame 11 includes a mounting horizontal plate 13 and a reinforcement vertical plate 14. The bottom ends of the first support beam 2 and the second support beam 3 are positioned and installed on the top surface of the mounting horizontal plate 13. The bottom sides of the first support beam 2 and the second support beam 3 are respectively supported by the reinforcement vertical plates 14. The reinforcement vertical plates 14 are welded and fixed to the mounting horizontal plate 13. The top plate 10 is laid on the top surfaces of the mounting horizontal plate 13 and the reinforcement vertical plates 14.

[0033] In this way, the staggered arrangement of the reinforcing vertical plates 14 and the installation horizontal plates 13 can not only make the base more stable, but also facilitate the movement of the entire device through the overall welding state.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
