Description

Technical Field

[0001] The utility model mainly relates to the technology of cable connectors, in particular to a process cable connection tool for improving test efficiency. Background Art

[0002] In the process of aerospace testing and launching, various process cables are responsible for connecting various instruments on the rocket and on the ground to realize functions such as information transmission and power supply and distribution between the rocket and the ground. Damage to any process cable will affect the normal launch of the rocket and even cause irreversible serious consequences. Therefore, it is necessary to conduct a continuity test on each type of process cable in the rocket testing process to check whether the cable is damaged.

[0003] The traditional process cable continuity test usually requires the cooperation of two or three people. Two people are responsible for using a digital multimeter to make point-to-point connections between the corresponding contacts of the connectors at both ends of the cable, and one person is responsible for orally stating the number of the corresponding contacts. From the perspective of work efficiency, due to the different types of process cables, some cable connectors have many contacts, and the distribution of contacts at both ends of the same cable sometimes varies. Just finding the contact position requires a lot of energy from the tester. The entire cable continuity test process often takes several hours, which is not suitable for the high-frequency and short-cycle mission situation of existing rockets. From the perspective of test reliability, if the tester is a little slack in spirit, or the three people do not cooperate sufficiently, there will be jump points and leakage points, which increases the probability of error and affects the coverage of the test. Therefore, designing a tooling that is suitable for the continuity test of existing process cables has always been a technical problem that has attracted widespread attention in the industry. Summary of the invention

[0034] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the embodiments are not intended to limit the present invention. All similar structures and similar variations of the present invention should be included in the protection scope of the present invention.

[0035] like Figure 1-Figure 3 As shown, a process cable conducting tool for improving test efficiency provided by an embodiment of the utility model includes a conducting socket or a conducting plug:

[0036] The conductive socket comprises a socket shell 8, the two ends of the socket shell 8 are a plug-in end and a tail end respectively, and a socket dust cover 15, an insulator 4, a jack 2, a connecting cap 7, a cap gasket 5, a wave spring 6, a clamp ring 3 and a cable cover 1 are sequentially installed in the socket shell 8 from the plug-in end to the tail end; the socket dust cover 15 covers the plug-in end of the socket shell 8 to provide dust-proof protection for the tooling; the jack 2 is installed in the insulator 4 to form an insulator assembly, and the number, position and number of the jacks 2 are consistent with the number, position and number of the process cable pins to be tested, and the solder cups of each jack are connected in series with wires from small to large in the order marked on the insulator to form a short-circuit plug. The outer wall of the insulator 4 is provided with a groove, and the inner wall of the socket housing 8 is provided with a convex rib. After the groove of the insulator 4 and the convex rib of the socket housing 8 are aligned, the insulator assembly is installed into the socket housing 8, and after confirmation, the clamp ring 3 is clamped into the inner cavity of the socket housing 8 to fix it; after the insulator assembly and the socket housing 8 are assembled, the socket housing 8 assembly is installed at the step of the inner wall of the connecting clamp cap 7. The clamp cap gasket 5 and the wave spring 6 are inserted from the rear end of the socket housing 8 in turn, and then fixed with the clamp ring 3; a wire is welded on the welding cup of the jack 2, and the wire passes through the cable cover 1 to connect the multimeter.

[0037] The cable cover 1 is screwed onto the external thread at the rear end of the socket housing 8.

[0038] Among the components of the conductive socket, silicone rubber is provided at the joints of two connected components for insulation.

[0039] The conductive plug includes a plug housing 14, the two ends of which are a plug end and a tail end (such as Figure 3As shown: the left side of the picture is the tail end, and the right side is the plug end), the plug end is connected to the process cable to be tested, and the wire drawn from the tail end is connected to the multimeter. In the plug housing 14, plug dust cover 13, insulator 12, pin 10, clamp ring 11 and cable cover 9 are installed in sequence from the plug end to the tail end; the plug dust cover 13 covers the plug end of the plug housing 14 to protect the tooling from dust; the pin 10 is installed in the insulator 12 to form an insulator assembly, and the number, position and number of the pins 10 are consistent with the number, position and number of the cores of the process cable socket to be tested. The wires of each pin solder cup are connected in series from small to large according to the letter sequence marked on the insulator to form a short-circuit plug. The outer wall of the second insulator 12 is provided with a groove; the inner wall of the plug housing 14 is provided with a convex rib. After the groove of the second insulator 12 and the convex rib of the plug housing 14 are aligned, the insulator assembly is then installed into the plug housing 14 from the rear end of the plug housing 14. After confirmation, the second clamp ring 11 is clamped into the inner cavity of the plug housing 14 to fix it; a wire is welded on the solder cup of the pin 10, and the wire passes through the second cable cover 9 for connecting a multimeter. The second cable cover 9 is screwed on the external thread at the rear end of the plug housing 14; wherein, among the components of the conductive plug, silicone rubber is provided at the joints of the two connected components for insulation.

[0040] For a pair of matching fixtures for testing the same process cable, in order to complete the continuity test of all cores at one time, the pins or sockets inside the fixtures need to be connected with wires according to a certain rule. If the pins or sockets of one fixture are numbered from 1 and connected to adjacent odd and even numbers, the pins or sockets of the other fixture are numbered from 2 and connected to adjacent even and odd numbers. One end of the wire is welded to the pin or socket point that is not connected, and the other end of the wire passes through the cable cover, and the passing end is used to connect the multimeter. Taking the test of Y2 type 120-core process cable as an example, since the contacts at both ends of the cable are sockets, the conduction tooling is a pair of matching plugs A and B. When performing a conduction insulation test, pins 1 and 2, 3 and 4, 5 and 6, ..., 119 and 120 in plug A of the conduction tooling are connected correspondingly, and pins 2 and 3, 4 and 5, ..., 118 and 119 in plug B are connected correspondingly. After the two ends of the process cable are respectively connected to plugs A and B, 120 and the core wires are connected in series into one, and the wires led out from pins 1 and 120 of plug B are connected to a multimeter to achieve a one-time conduction test of the process cable.

[0041] When in use, since the electrical connector contacts at both ends of the process cable may be pins or sockets, there are three situations for a pair of matching fixtures: (1) both are conductive sockets; (2) both are conductive plugs; (3) one conductive socket and one conductive plug. If the process cable has an even number of cores, the two wires connected to the multimeter are on the same conductive fixture; if the process cable has an odd number of cores, the two wires connected to the multimeter are on two different conductive fixtures.

[0042] From the above, it can be seen that in a process cable conduction tooling for improving test efficiency, the series connection of all core wires of the tested cable is achieved through regular connection of jacks and pins, solving the problem of one-time testing of multi-core cables.
