Description

Connector for electronic device {Connector for electronic appliance}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for an electronic device, and more particularly, to a connector for an electronic device that can be easily attached and detached by securing a connection stability by having a push type detachable member.

In general, a connector used in a medical electronic device refers to a connection part used to serially connect each component of the electronic device. As such, a connector for connecting one circuit of an electronic device to another circuit is disclosed in Korean Patent Laid-Open Publication No. 98-085330 (name of the invention: an easy connector) and 98-067067 (name of the invention: a connection device of an electronic product). The connector is typically made of a combination of a female and a male.

However, the connector disclosed in the patent is difficult to easily perform the fastening and detachment of the socket and plug when connecting or disconnecting the components of the electronic device through the detachment of the socket and plug, the connection stability to the plug of the socket and the plug It was difficult to secure the connection stability of the wire. In addition, the connector can be applied to electronic communication equipment, etc., but it was insufficient to be applied to a precise medical electronic device conforming to the electronic equipment safety standard (IEC601), which presents more demanding standards.

In order to solve this problem, a medical device connector that is easily separated and provided is provided by Radel, Germany, and FIG. 1 illustrates a cross-sectional view of the medical device connector manufactured by the company.

Referring to FIG. 1, the connector includes a socket 100 and a plug 110 formed at a center of a female contact 125 and a male contact 165, respectively. Is done.

A front nut 105 is formed at one end of the socket 100 on which the screw groove 107 is formed on the outer circumference thereof, and a hexagon nut 115 is fastened to the screw groove 107. The female contact 125 corresponding to the mail contact 165 of the plug 110 is formed at the center of the socket 100, and the insulator 120 surrounds the female contact 125.

An insulator 150 is formed around the mail contact 165 of the plug 110 to surround the mail contact 165, and the fixing groove 130 formed on the inner circumferential surface of the socket 100 on the outer circumferential surface of the plug 110. A latch member 140 having a latching piece 145 corresponding thereto is formed. In addition, a collet 155 for connecting the electric wire and a collet nut 160 for fixing the collet 155 are mounted to the rear of the mail contact 165.

2A and 2B are cross-sectional views for describing the connector separation and engagement shown in FIG. 1.

Referring to FIG. 2A, when the plug 110 is coupled to the socket 100, when the latch member 140 including the threaded locking piece 145 is inserted into the socket 100, the latch member 140 may be inserted into the socket 100. The locking piece 145 of the) is fastened to the fixing groove 130 of the socket 100 and the plug 110 is coupled to the socket 100. On the contrary, when the plug 110 is removed from the socket 100, as shown in FIG. 2B, when the latch member 140 is pulled toward the plug 110, the locking piece 145 having a thread shape is connected to the socket 100. The plug 110 is separated from the socket 100 while exiting from the fixing groove 130.

However, the Radel medical device connector has some problems as follows, although the socket and the plug can be easily coupled and separated.

In the connector, there is a problem that the plug and the socket of the plug is not properly performed when tightening the collet nut made of a screw screw to secure the wire connected to the pins formed in the plug. That is, the screw-type collet nut for fixing the wire inevitably must be tightened in order to prevent the wire from loosening, and thus there is a fundamental disadvantage in that the coupling and disconnection of the connector are restricted.

In addition, the female contact formed in the socket of the connector is formed to enter about 3mm from the end of the socket in order to secure the coupling stability, but such a female may be formed in a state of 3 mm or more inward from the end of the socket In this case, the automatic detachment and attachment structure of the plug's socket is not constituted, but it is protruded on the opposite side, which has a fundamental limitation in miniaturization of the connector. In general, the smaller the connector, the more advantageous the system assembly. This principle applies equally to the extent of the pin inside the plug.

Moreover, the connector of the Radel company has a disadvantage that the structure of the connector is complicated by the latch member having a locking piece to operate in the front and rear and requires a lot of time and cost in the manufacture of the connector.

Accordingly, an object of the present invention is to provide a connector for an electronic device that is easy to fasten and detach a socket and a plug by having a push or slide removable member.

Another object of the present invention is to provide a connector for an electronic device that can easily fix a wire connected to a plug by a push or slide detachable member and at the same time secure a connection stability of the plug.

Hereinafter, a connector for an electronic device according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited to the following embodiments.

3 is a cross-sectional view of a connector for an electronic device according to an embodiment of the present invention, Figure 4 is a cross-sectional view of the coupling for the connector for an electronic device according to the embodiment of FIG.

3 and 4, the connector 200 for an electronic device according to an embodiment of the present invention corresponds to a socket 210 and a female contact 240 having a female contact 240 formed at a central portion thereof. It includes a plug 270 having a stepped cylindrical shape in which the mail contact 260 is formed in the center.

The socket 210 is mounted on one end of the first case 220 in which a screw groove is formed on an outer circumferential surface and an insertion hole 250 into which a plug 270 can be inserted into an inner circumferential surface and is in contact with the plug 270. The first nut 215, the fixing groove 230 formed on one inner peripheral surface of the first case 220, the female formed in the center of the first case 220 is connected to the mail contact 260 of the plug 270 And a first insulator 235 formed around the contact 240 and the female contact 240. At this time, the female contact 240 is formed at a position that enters the inside of the socket 210 by about 4 mm from the outer end surface of the socket 210. That is, the distance between the female contact 240 and the outer end face of the socket 210 is about 4 mm.

In the case of the above-mentioned Ladell's connector, since the latch member is moved back and forth, the plug is detached from the socket, but for this operation, the female contact had to be located about 3 mm from the outer end of the socket. Since the plug 270 is separated from the socket 210 through the detachable member 280, the female contact 240 may be formed at a position about 4 mm from the outer end surface of the socket 210.

The plug 270 is formed at the center of the second case 275 having a stepped cylinder shape and is connected to the mail contact 260 and the mail contact 260 connected to the female contact 240 of the socket 210. The formed insulator 290 and the second case 275 are mounted to a portion into which the socket 210 is inserted, and the push piece detachable member having a locking piece 285 corresponding to the fixing groove 230 of the socket 210 is formed at the front. 280 and a threaded second nut 265 formed at one end of the second case 275.

In addition, when the plug 270 is detached from the socket 210, when the push type detachable member 280 is pressed, the locking piece 285 is fixed to the socket 210 by the elasticity of the push type detachable member 280. When the plug 270 is retracted from the 230 and retracts the plug 270 in this state, the plug 270 may be easily separated from the socket 210.

In the connector 200 according to the present embodiment, unlike the above-described Ladel's connector, a pin in the plug 270 (not shown) is performed because the plug 270 is detached and coupled through the push-and-detach member 280. The plug 270 is connected to the socket 210 regardless of the tightness of the screwed second nut 265 even when the screwed second nut 265 is firmly tightened to fix the wire connected thereto. It is possible to improve the connection stability of the wire by tightening and tightening the second nut 265 because it can be coupled to or separated from the socket 210.

In addition, since the female contact 240 is formed at a position that enters the inside of the socket 210 by about 4 mm, the standard proposed by the electronic device safety standard IEC601 can be sufficiently satisfied.
