Abstract

(57) [Summary] [Purpose] To enable the female connector of the mini coaxial connector to connect to multiple different male connectors. [Structure] A male screw is projected on the outer peripheral wall surface of the female connector, and a fitting step is provided at the tip of the male screw. As a plurality of male connectors to be connected to this female connector, a screw type in which a female screw is provided on the inner peripheral wall surface of the nut, a contact spring is arranged on the step of the inner peripheral wall surface of the shell, and is fitted to the mating step of the female connector. A push type is used, and a slide type is formed in which a slit is formed at the tip of the shell and this is pressed by a ring spring. [Effect] Since the female connector can support a plurality of male connectors, a combination with the male connector can be selected as appropriate according to the specifications.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a male connector and a female connector used in a mini UHF coaxial connector, etc., and provides a female connector that can support three types of male connectors (screw-on, push-on, and slide-on).

[0002]

[Prior Art]

 The screw-on type is adopted as the mini UHF coaxial connector. Female threads are engraved on the inner wall surface of the male connector shell, and male threads are projected on the outer wall surface of the female connector shell. A strong electrical connection and the like can be obtained by screwing both screw parts together. The most popular push-on type is a combination of a mating part and a spring fitted to it, and both types are used according to the application.

[0003]

[Problems to be solved by the device]

 The widespread use of other types of small-quantity production methods also appears in the characteristic requirements for connectors, and screw-on, push-on, etc. are often used in one device. Since each type has its own connection characteristics, it is difficult to unify them into one type. The present invention is to provide a common female connector that can accommodate different types of connectors (male connectors) without deteriorating the connection characteristics of each connector, which will be described in detail below with reference to the drawings.

[0004]

[Means for Solving the Problems]

 A male screw is projected on the base of the outer wall surface of the female connector shell, a fitting step is arranged on the outer wall surface in front of this male screw, and a cylindrical center contact is arranged inside this shell through an insulator. Form a female connector. Among the male connectors that fit into this female connector, the push-on method is used to form a step on the inner peripheral wall surface of the shell and place the contact spring that fits the mating step of the female connector inside this step. Form a male connector. As a slide-on type, the tip of the shell is slit and a ring spring is placed at this tip to form a male connector. In addition, as a screw-on type, a female connector that engages with the male thread of the female connector is engraved on the inner peripheral wall surface of the nut to form the male connector.

[0005]

[Action]

 To fit a male connector (Fig. 2) in which a female screw is engraved on the inner wall surface of the nut into the female connector of the coaxial connector, engage the two and rotate the nut gradually, While inserting the center contact of the male connector into the contact, tighten this nut to the extent that it can be rotated. The nut is firmly screwed into the female screw of the female connector. Another feature of the present invention is that a male connector of another type can be connected to this female connector. In the case of the push-on type male connector of Fig. 3, simply plug the male connector by mating both connectors. Good. The ring-shaped contact spring fits into the fitting step of the female connector, and the axial movement of both connectors is restricted. At this time, both center contacts are also closely fitted. This ring-shaped contact spring has an annular protrusion in the center and has a slightly curved shape from the center to the periphery. This sled acts as an elastic force and strongly digs into the fitting step of the female connector. The advantage of the push-on type is that the connector can be easily connected. Simply pull on the male connector to disconnect the connector.

In the case of the slide-on type male connector of FIG. 4, after mating with the female connector of FIG. 1, this male connector can be pushed in at a stretch. The tip of the slit contacts the male screw of the female connector, and the elastic force of the ring spring holds the male screw in the slit. Since the contact resistance between the slot and the male screw is large, a strong connection is maintained with the male screw once pressed. Since there is a matching step at the slit part, the contact state with both center contacts is always kept constant. Simply pull out on the male connector to separate them.

[0007]

[Means for Solving the Problems]

 A male screw 2 is projectingly provided on the base of the outer peripheral wall surface of the female connector shell 1, a fitting step 3 is arranged on the outer peripheral wall surface in front of the male screw 2, and a cylindrical center contact 4 is provided through an insulator. 1 to form a female connector 5. The ring-shaped fitting step 3 has a semi-arc cross section, and has sliding surfaces 6 lower than the male screw surface on both sides thereof. There are three types of male connectors that correspond to this female connector 5. First, the popular type screw-on type male connector will be explained. A nut 10 having a female screw 9 engraved on its inner peripheral wall is rotatably attached to the tip of a shell 8 that holds the base of the center contact 7 through an insulator. The nut 10 becomes an external contact. The nut 10 is screwed onto the male screw 2 of the female connector 5 to connect both connectors.

Next, the male connector shown in FIG. 3 will be described. A step 11 is formed on the inner peripheral wall surface of the shell 8 having the center contact 7, and a contact spring 12 which fits into the fitting step 3 of the female connector 5 is arranged in the step 11. The ring-shaped contact spring 12 has an annular protrusion in the center and has a shape that is slightly curved from the center to the periphery. This sled acts as an elastic force and strongly digs into the fitting step 3 of the female connector 5. Since the contact spring 12 whose movement is restricted in the step 11 fits firmly into the fitting step 3 of the female connector, the connection state of both connectors is extremely strong. Not only the movement of both connectors in the axial direction but also the movement in the circumferential direction is restricted.

In the male connector of FIG. 4, the tip of the shell 8 is slit, and a ring-shaped recess is formed in the outer peripheral wall surface of the tip, and the ring spring 13 is arranged therein. The inner diameter of the shell 8 that holds the center contact 7 through the insulator is slightly larger than the sliding surface 6 of the female connector. A step 14 is provided on the slotted portion at the tip of the shell so that the step 14 contacts the male screw of the female connector.

[0010]

[Effect of the device]

 In short, the present invention has a male screw 2 projecting from the base of the outer peripheral wall surface of a female connector shell, and a fitting step 3 is arranged on the outer peripheral wall surface in front of this male screw. The female connector 5 is formed by arranging it in this shell, and it is not possible to support three types of male connectors. A screw-on type male connector in which a female screw is drilled on the inner peripheral wall surface of the nut 10 In order to provide a push-on type male connector with contact springs 12 on the peripheral wall surface and a slide type male connector in which the shell tip is slit and pressed by the ring spring 13, multiple male connectors with a common female connector are provided. It is possible to combine with and meet the demand for small-scale production of other products.
