Description

  The present invention relates to a one-touch full-lock connector that is also applied to N-type and SMA-type female connectors.

  N-type plugs and SMA-type plugs are already known and are configured to screw-connect a female connector and a male connector.

Since the N-type plug and the SMA-type plug are screw-coupled, the coupling is loosened over time, and the tape is wound at the time of installation, and there is a problem that this tape-winding work takes time. Further, there is a problem that a tightening operation using a torque wrench that manages the tightening of the screw is necessary for screw connection.
In view of the above-described problems, an object of the present invention is to provide a one-touch full-lock connector that can be coupled to an N-type or SMA-type female connector with one touch.

  For this purpose, the one-touch full-lock connector of the present invention has an insulator fitted outside the center contact, a shell main body fitted outside the insulator, and the shell main body is cylindrical and spaced apart. An inner shell formed with a slit along the direction is press-fitted, a male connector with a slidable connection sleeve on the outside of the inner shell, and an insulator is fitted outside the center contact. A female connector having a shell body fitted thereto, and an outer bulging portion and an inner bulging portion are provided at the open end of the inner shell of the male connector, and the outer bulging of the inner shell is formed inside the connection sleeve. The female connector is provided with a coupling screw on the coupling-side surface of the inner shell of the male connector, while the cam surface is provided to displace the open end of the inner shell inward in cooperation with the inner portion. It is characterized in that is provided with a groove for receiving the bulge portion.

  The one-touch full-lock connector of the present invention has an insulator fitted outside the center contact, and a shell body fitted outside the insulator. The shell body is cylindrical and spaced apart along the axial direction. An inner shell with a slit is press-fitted, a male connector with a slidable connection sleeve on the outside of the inner shell, and an insulator is fitted on the outside of the center contact, and the shell body on the outside of the insulator An outer bulge and an inner bulge at the open end of the inner shell of the male connector, and the outer bulge of the inner shell on the inner side of the connection sleeve. The female connector has a cam surface for moving the open end of the inner shell inward, while the female connector is provided with a coupling screw on its coupling side surface. Received the department Since, characterized in that is provided with a groove to put, there are N-type, the effect of the male connector can be attached with a single touch of the present invention to SMA type female connector.

It is a judgment surface figure of the combined state of the male connector and female connector of a 2nd Example.

The details of the present invention are illustrated by the preferred embodiments shown in the drawings.
1 to 4 show a first embodiment of the one-touch full lock connector of the present invention. In the figure, reference numeral 1 is a male connector, and reference numeral 2 is a female connector.
As shown in the half sectional view of FIG. 2, the male connector 1 has an insulator 4 fitted on the outside of the center contact 3, and a shell body 5 is fitted on the outside of the insulator 4.
As shown in FIG. 2, the shell main body 5 has a cylindrical shape, and has a large diameter portion 5a having a large diameter. A second shell member 6 is fitted to the outside of the small diameter portion 5b having a small diameter behind the shell body 5. The second shell member 6 has a flange portion 7. Further, a small diameter portion 5c is provided in front of the large diameter portion 5a of the shell body 5, and an O-ring 14 is provided at a boundary portion between the large diameter portion 5a and the small diameter portion 5c.

  In the figure, reference numeral 8 denotes an inner shell, and this inner shell 8 is cylindrical, and is formed with spaced slits 9 and preferably equally spaced slits 9 along the axial direction of the male connector. The inner shell 8 is formed so as not to reach the rear end. That is, the slit 9 is not formed at the rear end of the inner shell 8. The rear end of the inner shell 8 where the slit 9 is not formed is press-fitted to the outside of the large-diameter portion 5 a of the shell body 5 and is held by a holding metal fitting 10. An outer bulging portion 12 and an inner bulging portion 13 are provided at the open end of the inner shell 8.

  A connection sleeve 11 is slidably provided outside the inner shell 8. The connection sleeve 11 is slidably fitted and supported on the outside of the holding metal fitting 10. The front end of the connection sleeve 11 forms a bent front end 15 that is bent inward, and has a cam surface 16 that is inclined inward at a slightly rear position thereof, and is formed between the bent front end 15 and the cam surface 16. The outer bulging portion 12 at the front end of the inner shell 8 is received in the recessed portion. Further, a washer 18 is fixed to the rear end of the connection sleeve 11, and the inside thereof is slidably contacted with the surface of the second shell member 6.

  A female connector 2 is shown in FIG. 3, and as shown in the half section of FIG. 3, the female connector 2 has an insulator 22 fitted on the outside of the center contact 21, and a shell body on the outside of the insulator 22. 23 is fitted. The female connector 2 is provided with a screw 24 on the outer side of the coupling end so as to be compatible with an N-type plug and an SMA-type plug. A concave groove 25 is provided on the outer periphery of the intermediate position of the shell body 23, and the inner bulging portion 13 at the tip of the inner shell 8 of the male connector 1 is fitted into the concave groove 25 so as to cooperate. It is. An O-ring 26 is provided slightly behind the concave groove 25 of the shell body 23.

  The male connector 1 shown in FIG. 2 shows a state before being coupled to the female connector 2. In order to connect the male connector 1 and the female connector 2 to each other, the male connector 1 is connected to the female connector 2 so as to be fitted on the outside thereof. That is, since the outer bulging portion 12 of the inner shell 8 of the male connector 1 is in the recess 17 inside the connection sleeve 11, the open end of the inner shell 8 is in an expanded state. Therefore, the male connector 1 can be fitted into the female connector 2 in a state where the female connector 2 is inserted from the opening of the male connector 1.

  In this manner, when the connection sleeve 11 is slid in the left direction in FIG. 2 with respect to the shell body 5 and the inner shell 8 with the male connector 1 fitted to the female connector 2, the cam on the inner surface of the connection sleeve 11 is obtained. The surface 16 functions to get over the bulging portion 12 outside the tip of the inner shell 8 and tighten the open end of the inner shell 8 inward, and the bulging portion 13 inside the open end of the inner shell 8 is a female connector. 2 and the male connector 1 and the female connector 2 are connected and coupled. At this time, as shown in FIG. 4, the washer 18 at the rear end of the connection sleeve 11 abuts the holding metal fitting 10, and the tip of the female connector 2 is pressed against the O-ring 14 of the male connector 1. Secured.

  5 to 8 show a second embodiment of the one-touch full lock connector of the present invention. The second embodiment has almost the same configuration as the first embodiment, and there are only slight differences in the detailed members. Accordingly, the members indicated by the reference numerals shown in FIGS. 5 to 8 are the same members as those in the first embodiment shown in FIGS. The connecting and coupling of the male connector 1 and the female connector 2 is exactly the same as in the first embodiment.
