Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] Kinoe QIJ relates to connectors and, more particularly, to an assembly for preventing undesired separation of a pair of mated connectors. .

[Prior art]

The connector assembly is formed by a pair of connectors having housings that are force-coupled by a coupling nut rotatably mounted on one of the housings. Each housing includes a dielectric insert, each insert having a number of holes in which electrical contacts are retained. A coupling nut generally includes a threaded portion.

The threaded portion is screwed into a threaded portion provided on the other housing. Those threaded parts are screwed together,
The combined nuts are turned! Upon rising, both housings are drawn together, coupling the contacts within the housings. Because mated connectors used in aviation are subject to considerable vibration, it is necessary to maintain the connector housing in a mated relationship even when subjected to concussive forces.
An example of such a configuration is disclosed in U.S. Pat. No. 4,109.990. a coupling nut having a number of teeth extending radially outwardly about the outer periphery and a flange ring rotatably mounted on the other housing and provided with a circular hole, and a coiled portion forming the hole; a semi-transverse protrusion that engages with the teeth; and a pin that is press-fitted into the circular hole of the coupling nut and the hole of the spring to seat the spring inside the coupling nut.

The part of the pin that is inserted into the circular hole of the coupling nut is square in shape, and is fitted into the four corners cut into the wall of the circular hole of the coupling nut, fixing the pin to the coupling nut. Stir. The pin is formed by forming a cylindrical pin with a screw machine and then forming four flat bottoms on one end and four edges with a milling machine. Pins can also be made from square material, but such material is more expensive than round material and requires more manufacturing steps to make the pin.

Recently, in the types of connectors mentioned above, problems can occur when the threaded part of the coupling nut cannot be completely tightened into the threaded part of the other housing, or when the threaded part is restrained. It recognized. In some cases, the electrical connections between competing contacts are shorted. These problems are caused by metal pieces between the threads and contacts. Metal chips between the threads can also cause unnecessary wear on the threads. As a result, care must be taken to remove any particles or particles from the threads after threading the coupling nut and housing. However, the problem remained until it was recognized that the pin that attaches the spring to the inside of the coupling nut would also form when the pin was press-fit into the circular hole. If these Paris cannot be removed, the above-mentioned problems will remain and the Paris will become a spring. kf
The bending of the spring is prevented due to the presence of
! IE preventive measures will be adversely affected.

[Summary of the invention]

The present invention eliminates the spall that has heretofore been caused by bottles attached to kits that combine anti-separation springs. The invention is characterized by a mounting pin having a helical thread at its end that is press-fit into a circular hole in a coupling nut.

Accordingly, an advantage of the present invention is that it heats away the metal burrs that are created when the bottle is used to attach the anti-separation spring to the coupling nut.

Another advantage of the present invention is that the fitted bins can be made in the 1st year 11M pattern without the need to use a second machine to mechanically shave the -I71 (flat'11) of the fitted bottles. This means that the cost of printing can be lowered.

Yet another advantage of the present invention is that the bin can be made from round wood and there is no need to use more expensive square bins.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a mounting bin 10 incorporating the principles of the present invention. One end of this mounting bin 10 includes a Pf& helical thread 11 and the other end includes a narrow diameter cylindrical portion 12 terminating 5114 in a tapered end 13. Tapered end 13
is to facilitate insertion of the bottle 10 into the hole or passageway. End 14 of threaded portion 11 is tapered to facilitate entry of threaded portion 11 into the passageway.

The angle of the zero surface and the angle of the spring projection 21 are determined to resist rotation of the coupling nut 40 in a direction that separates the coupling nut 40 from the housing 30.

Although two springs 20 are shown at 1941 in FIG. 2, for example, four springs can be strung together.

FIG. 3 shows how the bottle 10 attaches the spring 20 to the coupling nut 40. Spring 20 is a radially biasable member that includes a radial projection 21 and a coiled portion 22 forming a hole for receiving cylindrical portion 12 of bottle 10 in press-fit relationship. The coupling nut 40 includes a plurality of threaded portions 43 inside one end, and has a

is press-fitted into the circular hole 42.

When an axial force is applied to the vial 10 to press the vial 10 into the circular hole 42 of the coupling nut 40, the threaded portion of the vial 10 will pass through the wall of the circular hole 42, which would fit into a conventional vial. Unlike scraping away the material forming the wall and pushing the scraped material into the hole 42, the material of the wall is exposed between the crests of the threads. The inventor of this application does A4 when Paris is eliminated to make ηb. The threaded portions 11 of the bottle 10 rotate and penetrate into the material, so those threads 11

It can be made by manufacturing one screw for 10 bottles including the principle of the present invention, and forms a part in the part of the bottle that is inserted into the connecting nut 400 and the circular hole 42. 6. Flatten the bottle 10 to make it. There is no need to use a second F machine to scrape the surface.
