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 separated, and requires a sufficient coupling force so as not to be separated after 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 20 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 connecting member 13 having a connection hole 13a is inserted therein.

The male connector 20 includes a second body 21 and a second insulator 22 inserted into the second body 21. Inside the second insulator 22, a first connecting member 23 having a connecting pin 23a inserted into the connecting hole 13a is inserted. 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 such that rotation is permitted with respect to the second body 21 and the axial movement is limited by the stop ring 25 supported by the second body 21.

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 some problems listed below because the male and female connectors are coupled by screwing by a coupling cap.

First, disassembly and assembly had a difficult problem. That is, since the coupling cap 24 has to 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 tool to maintain a firm fastening state. It is. In particular, such a problem is to work as a factor that is less workability, such as difficult to insert the tool 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, since the screw coupling part is loosened due to the vibration, the connection pin 23a cannot be stably coupled to the connection hole 13a, so that contact failure occurs and the male and female connectors are separated. .

Accordingly, the present invention has been made to solve the above problems, the object is to provide a connector that can be easily disassembled assembly.

Another object of the present invention is to provide a connector that can prevent contact failure due to vibration and loosening of the screw coupling portion due to long-term use.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. 2 is a cross-sectional view showing the configuration of a connector according to the present invention.

According to FIG. 2, the present invention consists of a first assembly 100 and a second assembly 200 which are separated or combined with each other. 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. An elastically supporting spring 150 is interposed.

The second assembly 200 includes a second connecting member 220 having a connection hole 122 inside the second body 210 having a substantially cylindrical shape. A second insulator 230 that insulates the second connecting member 220 is interposed between the second connecting member 220 and the second body 210. In addition, 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 a locking step 246 coupled to the locking 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.

According to the present invention, an inclined surface 114 is formed on one side of the engaging groove 112, and an inclined surface corresponding to the inclined surface 114 of the engaging groove 112 on one side of the engaging jaw 246 of the collet 244. The collet part 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 a 248 and the first body 110 and the fastening member. 240 is configured to allow separation.

Looking at the operating state of the connector according to the present invention having such a configuration, as shown in FIG. 2, the connection hole 122 in a state in which the first assembly 100 is coaxially arranged with the second assembly 200 as shown in FIG. When the first assembly 100 is pushed toward the second assembly 200 so that the connection pins and the connection pins are engaged, the locking jaw 246 is extended radially outward by the outer diameter of the first body 110 and enters a predetermined depth. When entering, the tip of the collet 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 catching groove 112, the collet part 244 is elastically restored and the catching jaw 246 is inserted into the catching groove 112, and at the same time the collet part 244. The fixture and the slide cap 140 that were retracted by the spring is advanced by the elastic restoring force of the spring 150. This state is shown in FIG. 3, when the fastener 142 is returned, the collet portion 244 is limited to radial outward expansion 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, even if the first body 110 is pulled out, the collet portion 244 from the first body 110 Since it does not break out, it maintains a firm coupling state.

On the other hand, when the retracted slide cap 140, as shown by the arrow in Figure 3, the slide cap 140 is compressed to the spring 150 to retreat to the position shown by the virtual line. Therefore, the fixture 142 is to be out of the outer periphery of the collet portion 244, thereby allowing the expansion of the collet portion 244. 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 locking 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, of course, the relative position of the slide cap 140 and the first body 110 by the elastic restoring force of the spring 150 will also be returned to its original state.

As described above, the connector according to the present invention has a fastening member having a collet portion fixed to the first body and extending outward in a radial direction and forming a locking groove coupled to the collet portion at one end of the second body, and the first body The connection and disconnection of the first body and the second body can be easily achieved by limiting or allowing expansion of the collet portion radially outwardly by a slide cap that is supported to move a limited distance in the axial direction. Therefore, since the present invention enables the assembly and separation of the first assembly and the second assembly by one-touch, greatly improving workability does not require a separate assembly tool after assembling, in particular, to maintain a firm coupling state Since it is to be maintained as having an effect that there is no fear of separation after bonding.
