Description

Connector and electronic device having the same {CONNECTOR AND ELECTRONIC DEVICE HAVING THERREOF}

The present invention relates to a connector for an electronic device and an electronic device having the same, and more particularly, to a connector and an electronic device capable of improving fastness and reducing size.

Recently, as a display device for electronic devices, a flat panel display device for light, thin, and short devices is mainly used instead of a cathode ray tube (CRT). As such a flat panel display device, a liquid crystal display (LCD), a plasma display panel (PDP), a field emission display (FED), a vacuum fluorescent display (VFD), and the like are being actively researched.

The flat panel display device is applied to large-sized electronic devices such as TVs as well as various portable electronic devices such as mobile phones, PDAs, and notebook computers. A signal such as current, voltage, control signal, etc. is supplied to implement an image. Typically, the supply of the signal is made through a connector.

1 is a diagram showing a connector of a conventional electronic device such as a display device. As shown in FIG. 1, a conventional connector connects a first connector unit 60 electrically connected to a flat panel display device and an external signal source of an electronic device and coupled to the first connector 60 to obtain a flat panel display device. It consists of a second connector unit 70 that supplies various signals such as current, voltage, and control signals.

The first connector part 60 includes a first body 61, a first FPC 62 disposed on the first body 61, and a first coupling member 68 disposed on the first body 61. ) is composed of The second connector unit 70 includes a second body 71, a second FPC 72 disposed on the second body 71, and a first coupling member 68 disposed on the second body 71 and It is composed of a second coupling member 78 for coupling.

A first conductive wire 63 is disposed on the first FPC 62 of the first connector unit 60, and a second conductive wire 73 is also disposed on the 2 FPC 72 of the second connector unit 70. When the first connector part 60 and the second connector part 70 are coupled, the signal from the external signal source passes through the first conductive wire 63 and the second conductive wire 73 to the LED. connected to

In the first coupling member 68 and the second coupling member 78, pins are arranged in two rows at regular intervals, and at this time, the interval between the pins of the first coupling member 68 is the second coupling member 78 is arranged smaller than the spacing of the pins of When the first coupling portion 68 and the second coupling portion 78 are coupled, the two rows of pins of the first coupling member 68 are disposed inside the two rows of pins of the second coupling member 78, thereby forming the first coupling member. The outer surface of the pin of (68) and the inner surface of the pin of the second coupling member 78 come into close contact so that the first coupling member 68 and the second coupling member 78 are coupled. That is, the first coupling member 68 ) and the second coupling member 78 are coupled by frictional force due to close contact with each other.

A metal pattern to which wires 63 and 73 are electrically connected is disposed on pin side surfaces of the first coupling member 68 and the second coupling member 78, respectively, and the first coupling member 68 and the second coupling member When 78 is mechanically coupled, the metal pattern formed on the side surface of the pin contacts each other so that the first coupling member 68 and the second coupling member 78 are electrically connected.

However, the following problems occur in the conventional connector having the above structure.

First, the size of the connector provided in the electronic device must be reduced in order to miniaturize the electronic device, but since the conventional connector is composed of a coupling member that is a structure, there is a limit to reducing the volume. A conventional connector has a structure in which a first coupling member 68 made of a molded material is disposed on the main body 62 of the first connector unit 60. At this time, the thickness of the main body 61 is about 0.15 mm, the thickness of the FPC 62 attached to the main body 61 is about 0.1 mm, and the height of the first coupling part 68 is about 0.96 mm. ) is about 1.21 mm, and considering the total thickness of electronic devices such as thin display devices that have been recently researched, this thickness is very thick, so there were many problems in implementing thin electronic devices.

Of course, the overall thickness of the first connector part 60 can be reduced by reducing the thickness of the body 61 or the height of the first coupling member 68, but the body 62 and the first coupling member ( 68) has a limit in reducing its thickness because it consists of a mechanical configuration.

Second, coupling between the first connector unit 60 and the second connector unit 70 is not easy. As described above, the first connector unit 60 and the second connector unit 70 are coupled mechanically, and the coupling is maintained by the adhesion and frictional force of the coupled pins. However, since the coupled pins must apply strong pressure to each other in order to maintain this bonding force, when the first connector unit 60 and the second connector unit 70 are coupled, the first connector unit 60 and the first connector unit 60 are coupled with a strong force. The second connector part 70 must be coupled. Therefore, since the first connector unit 60 and the second connector unit 70 must be accurately aligned and then coupled with strong force, coupling is not easy.

Third, attachment/detachment and damage of connectors due to impacts occur. In the conventional connector, since the first connector part 60 and the second connector part 70 are mechanically coupled by adhesion, when an external shock is applied, the coupling is released and the first connector part 60 and the second connector part 60 are coupled together. There is a problem in that the connector unit 70 is detached or the first connector unit 60 and the second connector unit 70 in contact with each other are damaged by impact. Particularly, when the first connector unit 60 and the second connector unit 70 are coupled, the pins of the first connector unit 60 and the second connector unit 70 collide, resulting in breakage of the pins.

The present invention is to solve the above problems, and a connector capable of reducing the size of the connector and simplifying the structure by coupling the connector not by mechanical force but by microscopic coupling force or magnetic force, and providing the same Its purpose is to provide a single electronic device.

In the present invention, the connectors are coupled by magnetic force or microscopic coupling force in order to prevent difficult coupling or damage to the connector by mechanical force by mechanically coupling the structures when coupling the connectors.

The connector includes a first connector part connected to the receiving part, a second connector part connected to the transmission part and coupled to the first connector part, a first electrode disposed in the first connector part, and disposed in the second connector part. It is composed of a second electrode electrically connected to the first electrode, and coupling means for coupling the first connector portion and the second connector portion.

The coupling means includes a first magnet member and a second magnet member respectively disposed on the first connector part and the second connector part. Since the first magnet member and the second magnet member have different polarities, they are attached to each other. At this time, the first magnet member and the second magnet member are respectively along the outer circumference of the coupling part of the first magnet member and the second magnet member. It may be arranged and may be distributed regularly or irregularly throughout the joint.

In addition, as the coupling means, a coupling means providing microscopic bonding force may be used. As such a microscopic coupling means, a microscopic hook locking member and an electrostatic member may be used.

And, the coupling means can be implemented by forming all or part of the first electrode and the second electrode as a magnetic material. At this time, some of the magnetic material may be configured separately or integrally with the first electrode and the second electrode.

In the present invention, in order to precisely align the first connector part and the second connector part, an alignment guide and an alignment groove may be disposed in the first connector part and the second connector part, respectively, and in the first and second magnet members. Alignment protrusions and alignment grooves may be disposed.

The connector of the present invention can be applied not only to flat panel display devices but also to all electronic devices that transmit and receive signals.

In the present invention, the following effects can be obtained by coupling the connectors not by mechanical force but by microscopic coupling force or magnetic force such as van der Waals force, static electricity, or Velcro.

First, since the present invention does not use a mechanical structure unlike the prior art, the structure of the connector is simplified and the thickness can be reduced.

Second, in the present invention, since the connectors are not coupled by mechanical force but by magnetic force or microscopic force, coupling of the connectors is easy and it is possible to prevent the connectors from being damaged due to impact or the like during coupling.

Third, in the present invention, the manufacturing cost can be reduced by a simplified structure.

The reason why connectors fail in conventional electronic devices is because connectors are coupled by mechanical force. That is, since the connector is coupled by mechanical force, not only the assembly process is delayed, but also the connector is damaged by the mechanical force itself.

In the present invention, in order to facilitate connector assembly and to prevent easy detachment of connectors coupled by external force, connectors are not coupled by mechanical force but coupled by other forces. As such force, in the present invention, magnetic force or microscopic surface coupling force is used. Since this magnetic force or microscopic surface binding force is not coupled by an external force, assembly is facilitated and damage due to excessive force does not occur.

The connector of the present invention can be applied to various electronic devices. For example, the electronic device of the present invention can be used to transmit various signals such as current, voltage, and control signals of the electronic device to the flat panel display device when the flat panel display device is mounted on the electronic device, and the light source of the liquid crystal display device. It can also be used to supply current from an external current source. The connector of the present invention can be used in all electronic devices that electrically connect a transmitter and a receiver for exchanging various signals.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram showing the structure of a connector according to a first embodiment of the present invention.

As shown in FIG. 2, the connector includes a first connector unit 160 electrically connected to a receiver that receives an external signal, such as a display device, and an electronic device that supplies signals to the display device, for example. It is composed of a second connector unit 170 connected to a transmission unit such as a signal source of

The first connector unit 160 and the second connector unit 170 are coupled so that the receiving unit is electrically connected to the transmitting unit, and various signals (eg, current, voltage, control signal, image signal, etc.) are transmitted from the transmitting unit to the receiving unit. ) is supplied.

The first connector 160 includes a first body 161 including a connecting portion and a coupling portion, a first FPC 162 disposed on the first body 161, and a conductive wire disposed on the first FPC 162. (163) and the first magnet member 165 arranged to surround the coupling portion in a band shape having a predetermined width at the coupling portion of the first body 161, and disposed at the coupling portion of the first body 160. It is composed of a protective film 164 and a plurality of first electrodes 167 disposed on the protective film 164 of the coupling part.

The first body 161 is formed in a hardened thin plate shape, and the first FPC 162 is attached to the upper connection part. At this time, the first body 161 may be made of a resin having good insulating properties. In addition, the first FPC 162 is made of a heat-resistant plastic film such as polyester (PET) or polyimide (PI), which is a soft material, and a conductive film such as an anisotropy conductive film (not shown). It is attached to the first body 161. In this case, the first PFC 162 may extend from the first body 161 and be flexibly attached to a component of an electronic device including a receiver, for example, a flat display device.

The coupling portion of the first body 161 is formed in a square shape and is disposed at an end of the connecting portion. At this time, the coupling portion is formed with a larger area than the connection portion in order to increase the coupling area with the second connector unit 70 and the electrical connection area.

The first magnet member 165 is disposed in the coupling part. The first magnet member 165 is formed in a band shape with a certain width and is disposed along the outer circumference of the coupling part. In the drawing, the first magnet member 165 is arranged to form a closed curve in a continuous band shape, but the first magnet member 165 does not need to be formed continuously. Since the first magnet member 165 generates magnetic force and is for coupling the first connector part 160 to the second connector part 170 by the magnetic force, the first connector part 160 and the second connector part 160 Any shape is possible as long as it can generate enough magnetic force to couple the unit 170.

For example, as shown in FIG. 3A, the first magnet member 165 may be disposed along the outer circumference of the coupling part of the first body 161 in the form of two or more discontinuous bands, As shown in FIG. 3B, a plurality of circular, elliptical, or polygonal magnets having a certain area may be disposed at regular intervals along the outer circumference of the coupling part of the first body 161. In addition, as shown in FIG. 3C, the first magnet member 165 may be formed in a circular shape, elliptical shape, or polygonal shape with a certain area, and may be regularly or irregularly distributed over the entire coupling portion. In this case, the first magnet member 165 may be disposed between the first electrodes 167 .

A protective film 164 is disposed on the coupling portion of the first body 161 . In addition, although not shown in the drawing, the first FPC 162 is positioned under the protective layer 164, and the protective layer 164 protects the conductive wiring 163 disposed on the first FPC 162.

A first electrode 167 is disposed on the protective layer 164 . The first electrode 167 is made of Al or an Al alloy having good conductivity and is electrically connected to the conductive wire 163 of the first FPC 162 disposed below. At this time, although not shown in the drawing, a contact hole is formed in the protective layer 164 so that the conductive wire 163 can be electrically connected to the first electrode 167 .

The first electrode 167 is formed in a set shape with a set area and is disposed in plurality in the coupling part. Each of the plurality of first electrodes 167 is respectively connected to a plurality of conductive wires 163 disposed on the first FPC 162 . That is, the plurality of first electrodes 167 insulated from each other are connected to the corresponding conductive wires 163, respectively. At this time, the conductive wire 163 and the first electrode 167 may be connected 1:1 or 1:many.

Meanwhile, although the first electrode 167 is formed in a square shape in the drawing, the first electrode 167 may be formed in a polygonal shape such as a circular shape, an elliptical shape, a triangular shape, or a pentagonal shape. In addition, although a specific number and area of the first electrodes 167 are disclosed in the drawing, the first electrode 167 of the present invention is not limited to this specific number and area, and the area of the coupling part, the first FPC 162 It is possible to configure various numbers and areas according to the number, line width, spacing, etc. of the conductive wires 163 to be disposed.

The second connector unit 170 includes a second body 171, a second FPC 172 disposed on the second body 171, a conductive wire 173 disposed on the second FPC 162, and a second connector unit 170. It is composed of two magnet members (175) and a second electrode (177). The second body 171 is made of a thin plate-shaped resin, and a metal pattern 173 connected to an external current source is disposed on an upper surface. Similar to the first connector part 160, the second connector part 170 is composed of a coupling part and a connecting part. At this time, the coupling portion of the second connector unit 170 corresponds to the coupling portion of the first connector unit 160 .

The second FPC 172 is made of a heat-resistant plastic film such as polyester (PET) or polyimide (PI), and is adhered to the second body 171 by a conductive film such as an anisotropic conductive film. At this time, the second PFC 172 may extend from the second body 171 and be flexibly attached to an electronic device including a transmitter.

The second magnet member 175 is disposed on the coupling part on the second body 171 and adheres to the first magnet part 161 of the first connector part 160 by magnetic force. Therefore, the first magnet member 165 and the second magnet member 175 have different polarities, for example, when the first magnet member 165 has an S pole, the second magnet member 175 has an N pole and the first When the magnet member 165 is the N pole, the second magnet member 175 is the S pole.

In addition, one of the first magnet member 165 and the second magnet member 175 is composed of a magnet, and the other is composed of a ferromagnetic or paramagnetic metal, and may be adhered to each other by magnetic force.

Since the second magnet member 175 contacts the first magnet member 165 of the first connector part 160, the second magnet member 175 is disposed in a region corresponding to the first magnet member 165. do. That is, when the first magnet member 165 is continuously formed along the outer circumference of the coupling portion of the first body 161, the second magnet member 175 is also continuously formed along the outer circumference of the coupling portion of the second body 171. , and when the first magnet member 165 is discontinuously disposed along the outer circumference of the coupling portion of the first body 161, the second magnet member 175 is also placed on the outside of the coupling portion of the second body 171. A plurality of discontinuously arranged along the circumference. In addition, when the first magnet member 165 has a circular, elliptical, or polygonal shape with a certain area and is regularly or irregularly distributed in the coupling portion, the second magnet member 175 is also regularly or irregularly distributed in the coupling portion. can That is, the second magnet member 175 is disposed in a region corresponding to the first magnet member 165 shown in FIGS. 3A to 3C.

A protective film 174 is formed at the coupling part of the second body 171 and a second electrode 177 is disposed thereon. The second electrode 177 is electrically connected to the metal pattern 173 of the second body 171 disposed on the lower side, made of Al or an Al alloy having good conductivity. At this time, although not shown in the drawings, the protective layer 174 has a contact hole so that the metal pattern 173 can be electrically connected to the second electrode 177 .

The second electrode 177 is in contact with the first electrode 167 . Due to the contact, the first electrode 167 and the second electrode 177 are electrically connected, and the signal of the transmitting unit applied to the second electrode 177 is supplied to the receiving unit through the first electrode 167. At this time, in order to facilitate electrical connection between the first electrode 167 and the second electrode 177, a contact protrusion 167a may be formed on the surface of the first electrode 167. When the surfaces of the first electrode 167 and the second electrode 177 are flat, it is ideal that the entire surfaces of the first electrode 167 and the second electrode 177 completely contact each other. Due to the surface roughness or inclination of 167 and the second electrode 177, the surfaces of the first electrode 167 and the second electrode 177 do not substantially completely contact each other. Due to such incomplete contact, current flow through the first electrode 167 and the second electrode 177 is not smooth, and as a result, light emission of the LED 152 is incomplete, which causes a defect in the liquid crystal display. .

In the present invention, by disposing a plurality of contact protrusions 167a on the surface of the first electrode 167, even when the surfaces of the first electrode 167 and the second electrode 177 are rough or inclined, the first electrode By making constant contact between 167 and the second electrode 177, it is possible to maintain constant current supply to the LED 152.

As such, since the contact protrusion 167a is for contacting the first electrode 167 and the second electrode 177, as shown in the drawing, the contact protrusion 167a is the surface of the first electrode 167. It may be formed on the surface of the second electrode 177 instead of on the surface of the first electrode 167 and the second electrode 177. In addition, the shape of the contact protrusion 167a is not limited to a specific shape, and various shapes such as a circular shape or a polygonal shape are possible, and various heights are possible. In addition, the density or distribution form of the contact protrusions 167a may be set in various ways. Since the contact protrusion 167a is a means for contacting the surface of the second electrode 177, any shape or structure may be used as long as it facilitates contact.

FIG. 4 is a view showing the structure of a connector having other contact means for improving the contact between the first electrode 167 and the second electrode 177 instead of the contact protrusion 167a. As shown in FIG. 4, in this structure, instead of forming a contact protrusion on the surface of the first electrode 167, a thin contact leaf spring 167b is disposed. The leaf spring 167b is made of a thin metal plate having good conductivity, and a partial region is bent once on the surface of the first electrode 167.

When the first connector part 160 and the second connector part 170 are coupled, the first electrode 167 and the second electrode 177 come into contact, so that the second electrode 177 comes into contact with the leaf spring 167b. ) and at the same time apply pressure in the downward direction. Since the plate spring 167b has elasticity, as the second electrode 177 applies pressure in the downward direction, a restoring force acts in the upward direction. Because the contacted leaf spring 167b comes into close contact with the surface of the second electrode 177 due to this upward restoring force, the surfaces of the first electrode 167 and the second electrode 177 are rough or inclined. Even in this case, the first electrode 167 and the second electrode 177 are electrically connected reliably.

In the drawing, the leaf spring 167b is disposed on the surface of the first electrode 167, but may be disposed on the second electrode 177, and may be disposed on both the surfaces of the first electrode 167 and the second electrode 177. may be placed.

However, means for improving the electrical contact between the first electrode 167 and the second electrode 177 of the present invention is not limited to the structure of the protrusion 167a or the leaf spring 167b, and electrical contact of various structures tools may be applied.

Referring back to FIG. 2 , surfaces of the first electrode 167 and/or the second electrode 177 may be doped with a semiconductor material. The doping of the semiconductor material forms an energy band with a constant band gap on the surface of the first electrode 167 and/or the second electrode 177, and when a voltage below a threshold value is applied, the voltage is applied to the first electrode 167 and/or the second electrode 177. It is possible to prevent electronic devices from malfunctioning due to the supply of low voltage because it is not supplied through the electrode 1670 and the second electrode 177. In this case, an intrinsic semiconductor material or an impurity semiconductor material may be used as the doped semiconductor material. there is.

As described above, in the connector according to the first embodiment of the present invention, the first connector unit 160 and the second connector unit 170 are coupled by magnetic force rather than mechanical force, and the LED 152 is transmitted from an external current source. supply current. Therefore, the first connector unit 160 and the second connector are connected by the attractive force of the first and second magnet members 165 and 175 having different magnetic properties without the need to apply mechanical force from the outside. Since the part 170 is coupled, coupling of the first connector part 160 and the second connector part 170 becomes easy, and the first connector part 160 and the second connector part 170 are damaged due to mechanical impact. will not occur.

Meanwhile, in this embodiment, the first connector part 160 and the second connector part 170 are not coupled by the structural structure, but are coupled by magnetic force, so the first connector part 160 and the second connector part 160 are coupled together. Accurate alignment of section 170 becomes difficult. That is, when the first connector unit 160 and the second connector unit 170 are coupled, the first magnet member 165 and the second magnet member 175 do not contact each other only in corresponding areas but in an arbitrary area. Because of contact, it becomes difficult to align the first connector unit 160 and the second connector unit 170. When the first connector unit 160 and the second connector unit 170 are misaligned, the first electrode 167 and Since the second electrode 175 does not accurately contact, a problem occurs in electrical connection.

Accordingly, in the present invention, an alignment guide 166 and an alignment groove 176 may be provided to prevent the first connector unit 160 and the second connector unit 170 from being misaligned. That is, referring to FIG. 3 again, a rectangular alignment guide 166 is formed on the first magnet member 165 of the first body 161 of the first connector unit 160, and the alignment guide 166 The first connector unit 160 and the second connector are formed by removing a portion of the second magnet member 175 of the second body 171 of the corresponding second connector unit 170 to form an alignment groove 176. When the unit 170 is coupled, the alignment guide 166 is located in the corresponding alignment groove 176, so that the first connector unit 160 and the second connector unit 170 can be precisely aligned. At this time, although each of the alignment guide 166 and the alignment groove 176 may be disposed, as shown in the drawing, in order to prevent twisting of the first connector unit 160 and the second connector unit 170, two It is preferable to have a plurality of pieces or more.

In the drawing, the alignment guide 166 is disposed on the first connector unit 160 and the alignment groove 176 is disposed on the second connector unit 170, but the alignment guide 166 is disposed on the second connector unit 170. and the alignment groove 176 may be disposed on the first connector unit 170. In addition, although the alignment guide 166 and the alignment groove 176 are configured in a specific shape in the drawing, the alignment guide 166 and the alignment groove 176 are disposed at positions corresponding to each other, so that the first connector unit 160 As long as the and the second connector unit 170 can be aligned, it can be configured in any shape.

And, in the drawing, the alignment guide 166 and the alignment groove 176 are separately provided in the first connector unit 160 and the second connector unit 170 to form the first connector unit 160 and the second connector unit 170. are combined in an aligned state, but the alignment method of the present invention can be made in various forms. For example, the first magnetic member ( 165) and the second magnet member 175, the first connector part 160 and the second connector part 170 when the first magnet member 165 and the second magnet member 175 contact each other by manpower. ) can be sorted.

That is, as shown in FIG. 5, the first magnet member 165 is formed by forming a plurality of alignment protrusions 165a and alignment grooves 175a on the first magnet member 165 and the second magnet member 175, respectively. And the second magnet member 175 can be joined and aligned at the same time by magnetic force. In this case, the alignment protrusion 165a may be formed of the same magnetic material as the first magnet member 165, and the alignment groove 175a may be formed by removing a part of the second magnet member 175. In addition, the alignment protrusion 165a and the alignment groove 175a are formed of a magnetic material having stronger magnetic force than the first magnet member 165 and the second magnet member 175, so that the first magnet member 165 and the second magnet member 175 are formed. When the two magnet members 175 are attached by magnetic force, the alignment protrusion 165a and the alignment groove 175a are formed in different regions of the first and second magnet members 165 and 175 by a stronger magnetic force. The first connector unit 160 and the second connector unit 170 may be aligned by applying a stronger attractive force.

In the drawing, the first magnet member 165 is provided with a plurality of alignment protrusions 165a and a plurality of alignment grooves 175a are disposed at corresponding positions of the second magnet member 175, but the first magnet member 165 A plurality of alignment grooves 175a may be provided and a plurality of alignment protrusions 165a may be disposed on the second magnet member 175 . In addition, the alignment grooves 175a corresponding to the alignment protrusions 165a may be arranged in various positions in various shapes, sizes, and densities.

As described above, in the present invention, since magnet members having different polarities are provided in the first connector and the second connector, respectively, and the first connector and the second connector are coupled by magnetic force, the first connector and the second connector are coupled by mechanical force. The first connector and the second connector can be easily coupled compared to conventional liquid crystal display devices in which the second connector is coupled.

In addition, since the mechanical structure is not used in the present invention, the structure of the connector can be simplified and its thickness can be minimized.

In the case of a conventional liquid crystal display, the thickness of the body is about 0.15mm, the thickness of the FPC attached to the body is about 0.1mm, and the height of the first coupling part, which is a structure, is about 0.96mm, and the thickness of the first connector is about 1.21mm. In the case of the present invention, the thickness of the first body 161 of the first connector 160 is about 0.15 mm, the thickness of the FPC attached to the first body 161 is about 0.1 mm, and the thickness of the first magnetic member 165 is about 0.45 mm, and the total thickness of the first connector 160 is about 0.7 mm. This thickness reduction is equally applied to the second connector 170 . Therefore, the thickness of the connector according to the present invention is reduced by about 42% compared to the connector of the conventional liquid crystal display device, and as a result, the thickness of the liquid crystal display device can be significantly reduced compared to the prior art.
