Description
Technical Field
The utility model relates to a detection area, concretely relates to cable joint vacuum test device.
Background
The wire and cable connector is required to be subjected to a pressure leakage test, so that the problems of cable moisture, insulation reduction, deterioration, local defects and the like can be better reflected, the protection requirement required by design is met, and hidden dangers are found and eliminated early. However, the operation of the cable pressure leakage test is complicated at present, so that a simple and efficient test device is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a cable joint vacuum test device to solve prior art complex operation's problem.
The utility model provides a cable joint vacuum test device, including negative pressure jar and gland, the negative pressure jar is the one end confined cylinder type jar body, is equipped with quick-connect plug on its blind end jar body and is used for connecting the trachea, and the outside protrusion in its open end jar body is followed as the gland mount pad, the gland compresses tightly the gland mount pad uses the bolt-up, be equipped with cable joint installing port connecting cable joint on the gland.

Drawings
Fig. 1 is a three-dimensional structure view of the embodiment of the present invention.
Fig. 2 is a front view of an embodiment of the present invention.
Fig. 3 is a top view of an embodiment of the present invention.
Fig. 4 is a sectional view of embodiment a-a of the present invention.
The device comprises a negative pressure tank 1, a gland 2, a quick connector 3, a gland mounting seat 4, a bolt 5, a cable connector mounting port 6 and an O-shaped sealing ring 7.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.
Examples
As fig. 1 ~ 4, the utility model provides a cable joint vacuum test device, including negative pressure jar 1 and gland 2, negative pressure jar 1 is the one end confined cylinder type jar body, is equipped with quick-connect connector 3 on its blind end jar body for connecting the trachea, and its open end jar body is outer along outside protrusion as gland mount pad 4, gland 2 compresses tightly gland mount pad 4 uses the fastening of bolt 5, be equipped with cable joint mount port 6 connecting cable joint on gland 3.
An O-shaped sealing ring 7 is further arranged between the gland mounting seat 4 and the gland 2. The O-shaped sealing ring 7 further strengthens the sealing property between the gland mounting seat 4 and the gland 2, and ensures that no leakage occurs between the gland mounting seat and the gland.
The quick connector 3 is sealed by using a raw material belt. The quick-connection connector 3 is externally connected with a negative pressure pump and a digital display negative pressure meter through an air pipe and is used for pumping air in the negative pressure tank 1 to form negative pressure. The thread seal tape is used for enhancing the sealing property between the quick connector 3 and the air pipe and ensuring that no air leakage exists between the quick connector and the air pipe.
Also comprises a blank cap. Before testing the cable, need install stifle when detecting testing arrangement, stifle with gland 2 has the screw of apposition, use behind gland 2 and the stifle after adding the sealing washer than bolt 5 is longer bolt will stifle and gland 2 fastening are in on gland mount pad 4 for seal completely the open end of negative pressure jar 1.
Working process
Before testing: install sealed pad and stifle additional on gland 2, will testing arrangement submerges completely and carries out pressure leak test in aqueous, and compressed air inserts, and the manometer shows when pressure is 0.4MPa, observes to have or not to leak, if no leak then can use testing arrangement carries out the test to cable joint next step, if appear leaking then need change testing arrangement to ensure the accuracy of test.
The testing process comprises the following steps: the cable joint is provided with a buckle and is clamped on the gland 2 after being inserted, so that the plane of the cable joint gland 2 is tightly attached, then an air pipe is inserted into the quick-connection connector 3, the device is vacuumized and maintained in pressure, the initial pressure is set to be-0.09 MPa, and then the pressure value is recorded every 5 minutes. And finally calculating the leakage amount.
The test is carried out under the conditions that the standard atmospheric pressure and the temperature standard are 20 ℃, and the relationship between the leakage amount and the pressure difference in unit time is as follows:
q is Vex (△ P/1.013 x 10A 5) x (60/T), wherein Q is leakage amount, △ P is differential pressure, Ve is equivalent internal volume, and T is detection time.
To sum up, the utility model provides a pair of cable joint vacuum test device, compact structure, reasonable in design, easy operation is not loaded down with trivial details, and has guaranteed that the detection achievement efficient is accomplished.
The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
