Description

Technical Field

[0001] This utility model relates to the field of power supply and signal wiring technology, and in particular to a male plug for aviation connectors. Background Technology

[0002] Aviation connectors are commonly used in electrical cable connections. Their multi-core signal connections allow for the sequential insertion of signal and power lines by adjusting the length of the pins. Existing aviation connectors are standardized and structurally stable and reliable.

[0003] See appendix Figure 3 Existing aviation connectors use male plugs for connecting cables. These plugs have relatively long core tubes, with the core body fitted at the front and the cable end for connecting the cable sleeve at the rear. Because the cable needle needs to be inserted into the core body, the length of the rear end of the core tube cannot be too long; otherwise, effective insertion of the cable needle will be impossible. Furthermore, the length of the rear end of the core tube also affects the screw-in depth of the cable sleeve, and the sealing performance between the core tube end and the cable will also be affected. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a male connector for aviation connectors, which screws a cable sleeve onto the rear end of the core tube, increasing the length of the encapsulation, ensuring the screw-in depth of the cable sleeve at the rear end, and improving the sealing performance between the cable and the cable sleeve.

[0005] The technical solution adopted by this utility model is:

[0006] A male connector for an aviation connector is characterized by comprising a core tube, a core body, and a cable sleeve. The core tube is fitted over the core body, and a flange is provided at the front end of the core tube. A front nut is fitted on the flange for mating with a female connector. A insertion hole is provided in the core body for inserting a cable needle. The rear end of the core tube is an externally threaded section. The front end of the cable sleeve is an internally threaded section, and the rear end is an externally threaded section. The front end of the cable sleeve is threadedly engaged with the rear end of the core tube for secure fastening. The length of the cable sleeve is more than twice the length of the core tube. A cable end is threadedly connected to the rear end of the cable sleeve, and the cable end has a cable hole.

[0007] Furthermore, a front sealing gasket is fitted onto the front end of the flange of the core tube, and the front end face of the front sealing gasket protrudes beyond the front end face of the core tube.

[0008] Furthermore, an annular groove is provided on the inner side of the internal thread section of the cable sleeve, and a rear sealing washer is provided in the annular groove. The front end face of the rear sealing washer is used to cooperate with the rear end face of the core tube for sealing.

[0009] Furthermore, vertical embossing is provided on the outer circumferential surface of the front nut and the cable sleeve.

[0010] Furthermore, the cable sleeve is provided with an external hexagonal portion for tightening the cable sleeve with a wrench.

[0011] Furthermore, the core tube, cable sleeve, front nut, and cable end cap are all made of aluminum alloy.

[0012] Furthermore, a notch is formed at the rear end of the cable sleeve, and the rear diameter of the cable sleeve is reduced. When the cable sleeve is tightened, the notch of the cable sleeve tightens the cable to form a sealed fixation.

[0013] The beneficial effects of this utility model are:

[0014] (1) The cable sleeve is set in a split manner, which makes it easier to insert the cable needle and at the same time ensures the sealing fit between the cable and the cable sleeve;

[0015] (2) The length of the cable sleeve is more than twice the length of the core tube, providing sufficient length for the cable sleeve to fix the cable;

[0016] (3) With a longer length, it is also difficult to reach the core when there is a leak at the sealing position between the cable and the cable sleeve. Attached Figure Description

[0028] The following detailed description, in conjunction with the accompanying drawings, illustrates the specific implementation of a male plug for an aviation connector according to this utility model.

[0029] See appendix Figure 1 , 2 The male connector of the aviation connector of this patent includes a core tube 1, a core body 2 and a cable sleeve 3, as well as a cable end cap 4 for sealing the cable.

[0030] The core tube 1 is fitted over the core body 2. The core body 2 has an insertion hole 5 for inserting a cable needle 6. The core body 2 and the core tube 1 are fixedly fitted together. The front end of the core tube 1 is provided with a flange 7, and a front nut 8 is fitted on the flange 7 for mating with the female plug. A front sealing washer 9 is fitted on the front end of the flange 7 of the core tube 1, and the front end face of the front sealing washer 9 protrudes from the front end face of the core tube 1.

[0031] The rear end of the core tube 1 is an external thread section, the front end of the cable sleeve 3 is an internal thread section, and the rear end is an external thread section. An annular groove 10 is provided on the inner side of the internal thread section of the cable sleeve 3, and a rear sealing gasket 11 is provided in the annular groove 10. The front end face of the rear sealing gasket 11 is used to cooperate with the rear end face of the core tube 1 for sealing.

[0032] The front end of the cable sleeve 3 is threadedly fastened to the rear end of the core tube 1, and the length of the cable sleeve 3 is more than twice the length of the core tube 1. The rear end of the cable sleeve 3 is threadedly connected to the cable end cap 4, which has a cable hole. The rear end of the cable sleeve 3 forms a notch (not shown in the figure), and the rear diameter of the cable end cap 4 is reduced. When the cable end cap 4 is tightened, the notch of the cable sleeve 3 tightens the cable to form a seal and fixation.

[0033] The separate design of the core tube 1 and the cable sleeve 3 not only makes it convenient for the cable needle 6 to be inserted into the core 2, but also allows the cable sleeve head 4 to fit the cable more tightly onto the cable sleeve 3.

[0034] Vertical grooves 12 are provided on the outer circumferential surface of the front nut 8 and the cable sleeve 3. An external hexagonal part 13 is provided on the cable sleeve 4 for tightening the cable sleeve 4 with a wrench.

[0035] Core tube 1, cable sleeve 3, front nut 8, and cable end cap 4 are all made of aluminum alloy, while core 2 is made of rubber.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
