Description

Separation prevention connector {A connector}

The present invention relates to a connector that is coupled to a pair of male and female for electrical binding, and more particularly, to ensure a stable holding force in a state in which the male and female connector is electrically connected, the separation and connection operation is operator It relates to a connector for preventing separation to be made easily by.

Conventional connectors, which are applied at the time of electrical connection of various electronic devices and cables, are connected by male and female coupling.

For example, a female or male connector is connected to a female or male connector connected to an end of a cable in a state where a female or male connector is fixed to an end or a housing of a cable connected to various communication devices, and serves to guide the cable.

However, when the external connector is connected and connected to the fixed connector as described above, it is usually connected by a screw coupling method, which causes a problem that the external connector is released from the fixed connector when an external force is generated due to frequent vibration. Has been.

Recently, in order to improve convenience in the housing of the equipment due to the compatibility between the connectors, a fixed connector is pre-installed and then a separate external connector connected with a cable is connected to the fixed connector. There has been a problem that is easily released when the back occurs.

In order to solve this problem, connectors for separation prevention have been proposed as patent registration No. 10-0332307 (connector) and patent registration No. 10-0646756 (miniature coaxial cable connector for separation prevention).

The former relates to a connector, in which a first connecting member having a connecting hole and an insulator are installed therein, and a second connecting member and an insulator having a connecting pin inserted therein and inserted into the connecting hole. In having a second body,

A fastener and a fastener formed on the outer circumferential end of the first body and protruding a stopper on the rear outer circumference thereof, while being disposed concentrically with the circumference of the first body and movably coupled to an inner surface thereof; It is provided with fasteners spaced apart to install a slide cap to be moved between the open position and the closed position, install a spring to support the slide cap in the closed position at all times between the stopper of the slide cap and the stopper of the first body, A collet portion capable of elastic extension to the radially outer side is formed by a plurality of slits formed in one axial direction, and a locking jaw coupled to the locking groove of the first body is formed on the inner circumferential surface of the collet portion to move the slide cap. Accordingly, the fastening member which is maintained in the coupled state with the first body or is allowed to be separated is fixedly installed in the second body.

This is, when the slide cap is retracted during separation, the slide cap is retracted by compressing the spring. Therefore, the fixture is allowed to extend from the outer periphery of the collet portion, thereby allowing the collet portion to expand. When the slide cap is further pulled in such a state, radial components of the axial force are generated on the inclined surfaces of the locking groove and the locking jaw so that the collet portion extends radially outward and is separated from the locking groove. If the slide cap is further retracted, the collet part is completely removed from the first body, elastically restored, and returned to its original state to complete the separation. At this time, the relative position of the slide cap and the first body is also returned to its original state by the elastic restoring force of the spring.

However, in the case of the above structure, when the slide cap is pulled to the rear during the separation operation, the fixture must be separated from the collet part. In this case, the initial separation operation is difficult because the slide cam is sandwiched between the collet part and the inside of the second body. And the structure is complicated.

The latter relates to a miniature coaxial cable connector for preventing separation, and a cylindrical coupler having protrusions protruding from inner ends of elastic pieces formed by cutout grooves is fixed to the inside of the body, and an insulator and a center conductor are connected to the inside of the cylindrical coupler. A female connector with pins sequentially installed; A male connector in which an insulator and a center conductor connecting pin are sequentially installed in a body in which a catching groove in which the catching protrusion of the elastic piece is caught is formed at an outer circumference; And installed on the outside of the male connector on the outer circumferential surface of the male connector body to prevent the male and female connectors from being separated from each other by blocking the elastic piece formed in the cylindrical coupling hole of the female connector when the female connector is coupled to the outside It is installed to be slidably movable, one end is provided with an elastic piece flap prevention rod that is fitted to the space between the body of the female connector and the elastic piece of the cylindrical coupling port, the inner surface of the engaging projection protruding on the outer peripheral surface of the male connector body A cylindrical slider on which the supporting jaw protrudes; A support ring fixed to one end of the body of the male connector to support one end of the spring; And the cylinder

It is composed of a separation prevention means having a spring installed between the type slider and the support ring to generate an elastic force to return the cylindrical slider to its original position.

This means that even if any impact or external pressure is applied from the outside of the female connector as long as the elastic piece spreading prevention rod of the cylindrical slider of the separation preventing means does not escape from the space formed between the body of the female connector and the elastic member of the cylindrical coupling port, As well as the elastic piece of the cylindrical coupler does not spread outwards, the male and female connectors are not separated from each other because the locking protrusion formed on the inner circumferential surface thereof is held in the locking groove of the male connector body.

On the other hand, in order to separate the male and female connectors from each other, first, by holding the cylindrical slider of the separation preventing means with one hand and pulling it to the right in the drawing, an elastic piece spreading prevention rod is formed between the body of the female connector and the elastic piece of the cylindrical coupler. In the state where it is to be released from the space part (i.e., the unlocking state), when the female connector is pulled to the left with a force slightly larger than the elastic force of the elastic piece, the locking protrusion of the elastic piece is released from the locking groove. The female connector can be simply disconnected from the male connector

However, the above-described structure, like the former structure, requires the cylindrical slider to come out of the space between the body of the female connector and the elastic piece of the cylindrical coupler when the female connector is coupled to the male connector, and the cylindrical slider is pinched. As it is fixed, the worker is not easily assembled, of course, there is a difficult problem separation.

Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to bind the slide according to the rear movement of the forced fit or the separation prevention when the external connector having a center conductor is coupled to the female connector of the body forming the connector. It is possible to make simple and stable connection. When disconnecting, the center conductor can be separated at the same time as the separation prevention device is moved backwards. To provide.

In order to achieve the above object, the present invention, in the connector for electrical connection, the female connector is connected to the center conductor guide pin having a connection hole to the outer end is coupled to the front end through the insulator on one side and on the other side A body provided with a male connector having a connection hole to connect the outer conductor to the center conductor guide pin; One side wraps the insulator and is fixed to the female connector and is fixed, and an elastic piece is formed by a plurality of incision holes formed along the circumference of the insulator, while maintaining a state spaced apart from the outer diameter of the insulator. An elastic coupler having a protective tube guide groove formed therein so as to insert a protective tube protecting the central conductor; A spring coupled to surround one side of the elastic coupler, the one end of which is supported by a front end of the female connector and the other end of which is supported by a locking jaw formed in the elastic coupler; It is coupled to wrap around the elastic coupler and the female connector, and is supported on the inner peripheral surface of the elastic piece tip outer diameter of the elastic coupling to prevent the opening of the elastic piece, is formed in the middle of the inner peripheral surface to support one end of the spring when moving backward A separation prevention tool formed with a spring support protrusion for compressing the spring; And a handle provided on one side of the separation prevention tool and protruding to move the separation prevention device.

In addition, it is possible to be provided to the outer side of the elastic coupler is wrapped with a protective cap that can be opened through the incision hole to maintain the elastic state in a circular state.

In addition, it is possible to further provide a moving washer so that the spring support protrusion of the separation prevention tool to the end of the spring to the engaging jaw of the elastic coupling port.

Therefore, the connector for preventing the separation according to the present invention can achieve a simple and stable connection by sliding the joint according to the forced insertion or rearward movement of the separation preventing member when the external connector having the center conductor is coupled to the female connector of the body, At the same time, the center conductor can be detached at the same time as the separation prevention device is moved backwards, thereby enabling easy detachment, while maintaining a stable binding state without being separated even when an external force is applied in the connected state.
