Description

Connector {CONNECTOR}

The present invention relates to a connector, and more particularly to a connector used for connecting electrical signals, including communication.

In general, the connector is used for the connection of electrical signals, that is, the connection of electronic devices and cables, or the connection between them. Representative examples of use include connection of antenna lines and connection of communication devices.

Such a connector is mainly composed of a female connector and a male connector that can be mutually coupled and detached, and requires a sufficient coupling force so as not to be separated after the coupling, and requires easy disassembly and assembly work.

1 shows a configuration of a conventional connector. Here is shown a state in which the female connector 10 and the male connector 20 is coupled. According to this, the female connector 10 has a first body 11 having a male screw 11a formed on one side thereof, and a first insulator 12 made of synthetic resin, which is inserted into the first body 11. It includes. Inside the first insulator 12, a first connection member 13 having a connection hole 13a is provided.

The male connector 20 includes a second body 21 and a second insulator 22 inserted into the second body 21. A second connecting member 23 having a connecting pin 23a inserted into the connecting hole 13a is provided inside the second insulator 22. The connecting pin 23a is configured to protrude a predetermined length in the axial direction from the end of the second insulator 22. On the other hand, a cylindrical coupling cap 24 is rotatably coupled to the outer circumference of the second body 21. The inner circumferential surface of the coupling cap 24 is formed with a female screw 24a which is screwed to the male screw 11a of the first body 11. The coupling cap 24 is configured to allow rotation with respect to the second body 21 by means of a stop ring 25 supported by the second body 21 and to limit axial movement.

The conventional connector having such a configuration rotates the coupling cap 24 while inserting the connecting pin 23a into the connecting hole 13a while the female connector 10 and the male connector 20 are disposed coaxially. By screwing to the male screw (11a) of the first body 11 is coupled in the state as shown in FIG.

However, the conventional connector having such a configuration has several problems listed below because the female and male connectors are coupled by screwing by a coupling cap.

First, disassembly and assembly had a difficult problem. That is, since the coupling cap 24 must be rotated several times when disassembling and combining, the work time is long, and in particular, the coupling cap 24 must be tightened by using a separate tool to maintain a tight tightening condition. I have it. This problem is more difficult to work because the insertion of the tool is difficult when working in a relatively narrow space.

Second, the coupling cap is loosened due to the vibration of the device and the elapsed time, which causes problems such as poor contact. That is, the screw coupling part is loosened due to the vibration, the connection pin 23a is not coupled to the connection hole 13a stably, so that contact failure occurs as well as the female and male connectors are separated. On the other hand, Korean Utility Model Publication No. 91-13087 and Utility Model Publication No. 1992-7795 include a first metal sleeve mounted on an female connector and having a stepped portion, and fixed on the first metal sleeve and convex in an outer circumference. The second metal sleeve formed by drilling a plurality of holes in the front part with a metal part, and a recess formed in the front circumference of the front inner side is provided on the second metal sleeve and has a step portion in the rear inner side to enable up and down flow. A third metal sleeve, a first spring and a slide sleeve inserted into a space portion generated between the first metal sleeve step portion and the second metal sleeve, and a second metal sleeve A female ornament having a second spring provided in the space formed between the lock portion and the third metal sleeve step portion, a stopper sleeve mounted to the second metal sleeve hole and fixed to the front end of the second metal sleeve; A connector is disclosed which includes a male connector mounted with a predetermined void and having an outer diameter fitted to the second metal sleeve, and having a recessed recess formed in the front circumference of the front outer side. Although the female and male connectors can be easily combined by a simple inserting operation without screwing, the slide sleeves elastically supported by the first spring and the third metal sleeves elastically supported by the second spring are mounted on the female connector. There are many components and the structure is too complicated. In addition, there is a problem that if the excessive force is applied to each stopper, the step is broken or the steel ball inserted into the hole of the second metal sleeve is broken, there is a lot of failure.

Accordingly, the present invention has been made in view of the conventional situation as described above, the object is to provide a connector that can easily perform disassembly and assembly of the female connector and the male connector, the other object of the simpler structure It is to provide a connector that can be manufactured easily and inexpensively.

An object of the present invention is a first body including a connection hole, a slide cap that is supported to move a limited distance in the axial direction relative to the first body on the outside of the first body, and the connection selectively inserted into the connection hole A second body including a pin, one side of which is fixed to the second body, the other side of which is selectively coupled to the tip of the first body, and the state of engagement with the first body is maintained or separated depending on the position of the slide cap It can be achieved by configuring the connector with the fastening member.

Hereinafter, the specific technical contents of the present invention will be described in more detail with reference to an embodiment of the present invention shown in the accompanying drawings.

That is, according to Figure 2 is a cross-sectional view showing a configuration of the connector according to the present invention, an embodiment of the present invention is shown in Figure 2 to 4, the connector of the present invention is a first assembly 100 is separated or coupled to each other ) And the second assembly 200. The first assembly 100 includes a first connection member 120 having a connection hole 122 inside the first body 110 having a substantially cylindrical shape. A first insulator 130 that insulates the first connecting member 120 is interposed between the first connecting member 120 and the first body 110.

The outer side of the first body 110 is provided with a slide cap 140 to move a limited distance in the axial direction with respect to the first body (110). The inner circumferential surface of the slide cap 140 is spaced apart from each other so that the fastener 142 and the fastener 144 is fixed, the outer peripheral edge of the first body 110 is disposed between the fastener 142 and the fastener 144 The stopper 116 is configured to protrude so that the slide cap 140 is allowed to move between the open position and the closed position, and the slide cap 140 is always in the closed position between the fixture 142 and the stopper 116. The spring 150 which elastically supports is interposed.

Meanwhile, the second assembly 200 includes a second connecting member 220 having a connecting pin 222 inside the second body 210 having a substantially cylindrical shape. A second insulator 230 is interposed between the second connecting member 220 and the second body 210 to insulate the second connecting member 220. And one side is fixed to the second body 210 and the other side is selectively coupled with the engaging groove 112 formed at the front end of the first body 110, the coupling state is maintained by the movement of the slide cap 140 Or a fastening member 240 that is allowed to separate.

The fastening member 240 is elastically extended radially outward by a plurality of slits 242, one side of which is inserted and fixed between the second body 210 and the second insulator 230 and formed axially on the other side. The collet part 244 is formed as possible, and the engaging jaw 246 coupled to the engaging groove 112 is formed on the inner circumferential surface of the collet part 244.

An extension part 249 is formed radially outward at the tip of the collet part 244 so that the extension part 249 is radially outwardly by the inner circumferential surface of the fixture 142 when the slide cap 140 is in the closed position. The expansion of the is configured to be limited.

In addition, the connector of the present invention forms an inclined surface 114 on one side of the engaging groove 112 of the first body 110, the engaging jaw 246 of the collet portion 244 of the engaging groove 112 The collet 244 extends radially outward with respect to the axial force acting in the direction in which the first assembly 100 and the second assembly 200 are separated by forming the inclined surface 248 to correspond to the inclined surface 114. 1 body 110 and the fastening member 240 is configured to allow the separation.

Looking at the operating state of the connector according to the present invention having such a configuration, as shown in Figure 2, the first assembly 100 and the second assembly 200 in the state arranged coaxially in the connection hole 122 When the first assembly 100 is pushed toward the second assembly 200 such that the connection pins 222 are coupled to each other, the locking jaw 246 is extended radially outwardly by the outer diameter of the first body 110 and enters. When entering a predetermined depth, the front end of the collet portion 244 interferes with the fixture 142. When the first assembly 100 is pushed further in this state, the spring 150 is compressed and the fastener 142 is pushed by the tip of the collet part 244. At this time, the slide cap 140 to which the fixture 142 is fixed is retracted together. Accordingly, when the collet part 244 continues to move forward and reaches the locking groove 112, the collet part 244 is elastically restored so that the locking jaw 246 is inserted into the locking groove 112, and at the same time by the collet part 244. The retracting fixture 142 and the slide cap 140 are advanced by the elastic restoring force of the spring 150. This state is illustrated in FIG. 3, when the fastener 142 is returned, the collet portion 244 is limited in radial extension outward by the fastener 142. Therefore, in the above state, that is, in the state limited to the radial expansion of the collet portion 244 by the fastener 142, the collet portion 244 is separated from the first body 110 even when the first body 110 is pulled out. It will not be possible to maintain a firm coupling state.

Meanwhile, when the slide cap 140 is retracted as shown by an arrow in FIG. 3, the slide cap 140 compresses the spring 150 and retracts to the position shown by the virtual line. Therefore, since the fastener 142 is out of the outer periphery of the collet portion 244, the expansion of the collet portion 244 is allowed. If the slide cap 140 is further pulled in this state, the radial portion of the axial force is generated in the inclined surfaces 114 and 248 of the locking groove 112 and the locking jaw 246 so that the collet portion ( 244 extends radially outward and is disengaged from the engaging groove 112. This state is shown in FIG. Subsequently, if the slide cap 140 is further retracted in the state of FIG. 4, the collet part 244 is completely separated from the first body 110, elastically restored, and returned to its original state to complete separation. At this time, the relative position of the slide cap 140 and the first body 110 is also returned to its original state by the elastic restoring force of the spring 150.

As described above, the connector according to the present invention is fixed to the second body 210 and has a collet member 240 having a collet portion 244 that extends radially outward and the collet at one end of the first body 110. A radially outer side of the collet portion 244 is formed by a slide cap 140 that forms a locking groove 112 coupled with the portion 244, and is supported to move a limited distance in the axial direction with respect to the first body 110. By limiting or allowing the expansion to the first body 110 and the second body 210 can be easily connected and disconnected. Therefore, according to the present invention, since the first assembly 100 and the second assembly 200 can be assembled and separated by one-touch, the workability is greatly improved, and thus, a separate tool for assembly and disassembly is not required. Since the solid coupling state is continuously maintained, it is possible to obtain an effect that there is no fear of separation after the coupling, and also installs only the slide cap 140 elastically supported by the spring 150 of the first body 110 and the second body. Since only a fastening member 240 is installed on the 210, it can be manufactured with a small number of parts and a relatively simple structure, and thus the manufacturing cost can be greatly reduced.
