Description

[Technical Field] The present invention relates to a composite connector unit,

In order to solve the problem that the 4-pin injection part can not be inserted into a space that is invisible even if it touches first, a deep groove is formed in a 4-pin female connector structure to change into a primary guide structure Pin connector structure to seat the circular RF connector at the seating point to solve erroneous insertion and to maximize productivity.

In general, various signals such as a data signal and a control signal are transmitted between wired / wireless communication devices, and they must be electrically connected to each other so as to transmit and receive the signals. Normally, a male connector and a female connector (female connector) is used to connect both sides.

That is, bidirectional communication is possible by providing a male connector to one communication device, a female connector to the other communication device, and a male connector and a male connector to each other. Meanwhile, in the case of transmitting and receiving a radio signal, an antenna capable of transmitting / receiving a radio signal to / from a communication device can be electrically connected using a female connector and a male connector.

Thus, various signals such as various data signals and control signals can be transmitted and received from one communication device to the other communication device through a female connector and a male connector, which are wired or wirelessly connected.

At this time, a plurality of signal pins are provided so as to be electrically connectable to the female connector and the male connector.

Conventionally, a structure of a composite connector capable of bidirectional communication is specifically known in "Circular type connector for composite cable (Patent Registration No. 10-1225048) ".

However, in order to simultaneously transmit and receive a plurality of control signals for controlling the operation of communication devices of the other party as well as the high frequencies used for data transmission, it is necessary to increase the number of connection lines such as coaxial cables for transmitting respective signals.

Accordingly, when a large amount of signals are transmitted and received between communication devices, the volume of the communication devices is increased, and the manufacturing cost of the communication devices is increased.

In addition, when connecting to a communication device in a bent form, it is difficult to bend a plurality of connection lines, and there is a problem that the use environment such as the location and area where the communication device is installed is very limited.

In this case, in the case of a sensitive signal such as a high-frequency signal, a plurality of signal pins for transmitting and receiving signals must be formed to have a constant length and to maintain a concentric circle.

However, when the number of wires or signal pins for transmitting and receiving signals increases, if the arrangement of the signal pins does not have a constant length, a length error is generated when transmitting a signal sensitive to a length such as a high frequency signal, And had problems.

In other words, a signal can be transmitted between the cable connectors by connecting one end and the other end of the signal cable to the pair of cable connectors. At this time, at the one end and the other end of the signal cable, In this case, since the separate connector itself occupies a large volume, it is difficult to design a thin electronic device, and the use of a separate connector raises the manufacturing cost.

On the other hand, as a kind of the composite cable, a coaxial cable and a flexible cable are sometimes connected, and a flat type cable (hereinafter referred to as a flat cable) such as an FPC (Flexible Printed Cable) or an FFC A connector for connection is provided in the form as disclosed in, for example, Korean Patent Laid-Open Nos. 2000-11259, 2006-310194, 2008-186600, and Korean Patent Registration No. 0879176.

That is, the connector for flat cable connection includes an insulator for accommodating a flat cable, and a plurality of conductive contacts which are inserted and fixed at a predetermined interval in the insulator to make contact with a signal layer as a signal transmission wiring layer formed on one surface of the flat cable .

However, in the conventional connector for flat cable connection, it is difficult for the operator to recognize whether or not the flat cable is inserted when inserting the flat cable, so that there is a weak point that connection failure often occurs. Further, when the flat cable is inserted into the insulator, there arises a problem that the flat cable is detached from the contact. Further, when the flat cable is inserted into the insulator, there arises a problem that the flat cable is detached from the contact. In addition, a separate structure is required for enhancing the mounting strength between the insulator and the printed circuit board, thus complicating the assembling process and increasing the size of the product.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to design a structure in which two types of connectors (an RF connector and a signal connector) are connected to an ultra-thin product, 4-pin female connector structure In order to solve the problem that the 4-pin injection part can not be inserted into an invisible space even if it touches first, the 4-pin signal connector structure is positioned And the circular RF connector is seated at the seating point to solve the erroneous insertion and to maximize the productivity.

The components of the present invention largely consist of a socket connector 100 for fixing a jacket and a connector 200 for fixing a jacket to be coupled to the jacket socket for fixing the jacket.

The socket fixing part 100 for socket fixing comprises a second RF connector 110 for a socket and a signal socket connector 120 in a housing 130. The second RF connector 110 The connector shaft 112 has a cylindrical body portion 111 and a cylindrical connector shaft 112 formed on the inner circumference of the cylindrical body portion. Is protruded.

The signal socket connector 120 has a rectangular rim surface 121 and a vertical surface 122 on the inner side of the rim surface and a plurality of connector elements 123 and connector holes 124 on the vertical surface. .

The jack fixing member 200 of the present invention includes a first RF connector 210 for a plug and a signal connector 220 for a plug and specifically includes an RF cable 201 and a signal cable 202, A first RF connector 210 is coupled to an end of the RF cable 201 and a signal connector 220 for a plug is connected to an end of the signal cable 202 .

The first RF connector for plug 210 includes a support 211 coupled to the inner periphery of the cylindrical body 111 of the socket second RF connector 110 and extends from the inside of the support 211 The terminal portion 212 is formed with a pinhole 213 at the center thereof for inserting the fixing pin 113 of the second RF connector 110 for socket and connecting it to the RF cable 201 .

The plug-type signal connector 221 and the plug-type 4-pin 222 are inserted into the signal socket connector 120 and the connector hole 124 while the plug-type 4-pin 222 is inserted into the connector hole 124 And the signal connector 221 for the plug is inserted into the signal socket connector 120.

Therefore, the fixing pin 113 of the second RF connector 110 for a socket according to the present invention is inserted into the second RF connector 110 when the first RF cable connector 210 for the plug is fitted in the second RF connector 110 Type signal connector 220 is connected to the signal socket connector 120 while the RF cable 201 and the signal cable 202 are connected to the pinhole 213 of the RF cable connector 210 by one- ) Connection is completed.

The socket fixing housing 130 is fixed to the socket connecting panel 140 and the connector connecting panel 230 is fixed to the connector connecting panel 230. [ So that the jacket fixing connector portion 200 is inserted and fixed in the socket fixing socket connector portion 100 by hand.

On the other hand, the plug signal connector 221 is usually made of a plastic material. In the present invention, since the front end body portion 221a of the plug signal connector 221 is made of a silicon material and has a deviation when inserted into the signal socket connector So that insertion and coupling can be performed more easily.

That is, in a state where the entire plug signal connector 221 is made of a plastic material, it must be manufactured to have an accurate numerical value such that the width thereof is inserted into the signal socket connector, and there is a slight deviation in the horizontal direction and the vertical direction There is a problem that mutual coupling becomes impossible.

In order to solve this problem, in the present invention, the front end body portion 221a of the plug signal connector 221 is made of a silicone material. When the front end body portion 221a of the signal connector for plug is made of a silicone material, The signal signal connector 221 can be inserted into the signal socket connector 120 more easily, even if the dimension of the signal connector 221 is not correct, so that the coupling correction can be made easier.

Since the rear end body portion 221 of the signal connector for plug is made of a rigid plastic material, a strong coupling force can be maintained.

That is, since the front end body 221a of the plug signal connector 221 of the present invention is made of a flexible silicon material, even when a plurality of coupling points are coupled with the initial signal socket connector 120, And the coupling end portion is made of a plastic material, so that strong coupling is prevented so that the coupling can be easily released after coupling.

In addition, the present invention is characterized in that a contact detection sensor 400 is installed at one end of a signal socket connector to check whether the plug type signal connector 220 is tightly coupled to the signal socket connector 120, A control unit 500 for checking information is provided. When the control unit determines that the contact is not properly performed, an automatic error signal output unit 1000 for outputting an alarm signal is constructed.

The error signal automatic output unit 1000 is configured to continue the alarm signal if the error condition is not released.

The configuration of the error signal automatic output unit 1000 of the present invention is as follows.

A contact power supply unit 1101, a contact error signal output unit 1102, an oscillation transformer 1103, a relay operation switching unit 1108, a relay switch 1107, a first circuit connection switch sw1, A communication terminal power switch sw2, and a power source holding switching section 1118. [

The power supply unit 1101 applies a power supply signal by itself.

The contact error signal output unit 1102 receives a signal from the control unit 500 and switches the power supply circuit when it is detected that the signal socket connector 120 and the plug type signal connector 220 are in an incomplete state.

When the power switch is turned on, the oscillation transformer 1103 is supplied with electric power to output a boosted AC current.

The switching unit 1108 for relay operation is connected to the output terminal of the oscillation transformer 1103 and is turned on by electrical supply.

The relay switch 1107 is installed at an output terminal of the relay operation switching unit 1108 and generates a magnetic force.

The first circuit connection switch (sw1) performs a function of energizing the circuit by pulling the iron wire by the relay switch (1107).

The power switch for outputting the error signal sw2 induces an error signal to be displayed by supplying power to the error signal output control unit 1140 while the iron strip is pulled by the relay switch 1107. [

The power supply switching unit 1118 is connected to the base end of the first circuit connection switch and the emitter end and the collector end are connected to the oscillation transformer 1103 and the relay operation switching unit 1108, The wire is pulled by the operation of the switch 1108 to form a closed circuit while switching is turned on, and then the operation of the relay switch 1107 is stopped. At this time, if the first circuit connecting switch sw1 and the error signal output power switch sw2 are forcibly turned off, the closed circuit is broken while the closed circuit is broken and the relay operating switch 1108 is turned on and the relay switch is turned on The first circuit connecting switch sw1 and the error signal output power switch sw2 are turned on to induce the error signal to be output continuously.

Hereinafter, the operation of the error signal automatic output unit 1000 will be described.

First, when the contact error signal output unit 1102 is turned on, a DC power source is connected to supply power to the oscillation transformer, and a high voltage is applied to the secondary side of the oscillation transformer.

The power source induced on the secondary side becomes a DC power source of a half wave through a rectifying diode, and this half wave DC power source becomes a more stable DC power source due to the charging and discharging action of the condenser.

This DC power source is applied to the anode terminal of the thyristor through the coil of the relay switch 1107, while the DC power source charges the capacitor through the resistor. The elevated voltage passes through the die and triggers the switching section 1108 for relay operation so that the node node and the cathode node are switched so that the operation of the relay switch is made, The circuit connection switch sw1 and the error signal output power switch sw2 are turned on to apply power to the error signal output control unit 1140 to display an error signal.

When the first circuit connection switch sw1 is activated, a base end of the power supply maintaining switch 1118 is activated, and a closed circuit is induced in the emitter end and the collector end of the power supply holding switch 1118 to supply power to the transformer Off.

That is, a voltage between the resistor 1109 and the capacitor 1110 flows through the diode 1120 to flow between the emitter terminal and the collector terminal of the power source holding switching unit 1118, and the resistance between the resistor by the bypass and the capacitor When the voltage between the resistor and the capacitor is lowered, the trigger signal to the switching unit for relay operation 1108 is stopped, so that the node end and the tail end are turned off and the current flows to the relay switch 1107 So that the power supply is continuously stopped for switching.

On the other hand, if the operator turns off the first circuit connecting switch and the error signal output power switch during the error signal output, there is no current flow in the closed circuit, and accordingly, the bias voltage flowing between the emitter end and the base end of the power- And the power supply switching unit 1118 is turned off.

The power supply switching unit 1118 is turned off to remove the bypass voltage between the resistor and the capacitor through the diode 1120 and the voltage is charged in the capacitor 1110.

The charged voltage causes a break-over phenomenon of the die 1111 and a trigger signal is output from the die to the switching section 1108 for auxiliary switch operation to move the iron piece, while maintaining the closed circuit, and at the same time, So that the error signal display unit 1150 can be continuously operated.

That is, according to the present invention, if the error factor is not healed, the warning sound is continuously output, and the connector is necessarily operated after the error factor is healed.
