RELATED APPLICATIONS 
   The present application claims priority to Korean Patent Application Serial Number 10-2008-0092538, filed on Sep. 22, 2008, the entirety of which is hereby incorporated by reference. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a velcro connector, and in particular, a velcro connector that is mounted on a garment to transfer electric signals and easily connects to an external circuit module or an external line. 
   2. Description of the Related Art 
   Recently, research and development of conductive fibers capable of conducting electricity while maintaining the characteristics of fibers have been progressed. Further, the already developed conductive fibers have been utilized to manufacture a garment for measuring physiological signals in the field of digital garment and health care. 
   Herein, in order to implement a communication line for communicating with a garment by using the conductive fibers or implement simple electronic circuits, contacts should be formed in the middle of the conductive fibers to connect with the conductive fibers. As methods according to the related art in order to achieve this, there is a method of manufacturing a dedicated connector by connecting a snap fastener or a conductive contact pad using soldering, conductive adhesive, embroidery, etc. As another method, there is a method of manufacturing a garment so as not to generate the connection contacts. 
   However, currently used methods for connecting the contacts of the conductive fibers have several disadvantages. For example, the method using a snap fastener scheme, in which the snap fastener holds a coupling force by using a magnet, it has an advantage in that the coupling can be easily performed. However, the snap fastener is appropriate to form about only two contacts, not a plurality of contacts on a garment. 
   Meanwhile, a method for forming contact pads on a garment and attaching them thereto by soldering or conductive adhesives or connecting them thereto by embroidery should be removed from a garment composed of conductive yarns. As a result, the contact pads should be separated or recoupled, if necessary, which is difficult to perform. In addition, in the case of a method for manufacturing an integral connector, an existing PCB connector should be fixed on a stable plate, however, it is difficult to fix the PCB connector on a garment and the connecting part is easily separated due to motion. Therefore, in order to use the existing PCB connector, the PCB should be used at the connector fixing portion or there is a need to develop a connector that can meet the following requirements. 
   When a method that manufactures a garment without contacts, a simple electric circuit such as a communication line can be implemented by seamlessly manufacturing a garment from beginning to end. However, in order to ensure a seam does not occur during the manufacturing process, a dedicated loom and knitting machine needs to be developed. 
   Meanwhile, Korea Unexamined Patent Application Publication No. 2008-0071299 discloses a velcro connector using a velcro tape. Herein, the velcro connector is weaved by using the same area of where a hook of the velcro tape and a loop part as a connecting part corresponding to the connecting part when weaving the textile, which is a conductive yarn, such that it transfers electric signals through the connecting part upon connecting the hook and the loop. The velcro connector uses one area, which is where the connecting part of the hook and the connecting part of the loop are coupled to each other, as one line. 
   In this case, a user should visually ensure the surfaces between the connecting part of the hook and the connecting part of the loop, etc., are accurately coupled a, such that the velcro connector can function as a connector. When the length of the velcro connector is formed to be long, the user should visually check the surfaces of the connecting part by matching each individual area, in order to make the signal line be connected, thus making it possible to use the signal line of the velcro connector. When the user does not confirm the surfaces of the connecting part provided in the hook and the loop and roughly couples them, a disconnection or a short with adjacent lines may occur. 
   In addition, the velcro connector forms some area of the hook and the loop as the conductive yarn in order to transfer the electric signals, but since the connecting part is the portion that is weaves together the hook and the loop, in order to transfer electric signals, the connecting part should maintain some degree of length or width, such that the number of lines is limited according to an area of the velcro tape. Thus, the number of connectable electric devices or circuit modules is also limited. 
   Moreover, since the velcro connector according to the related art does not propose the connecting method with the external line or the circuit module, a need exists for a more practical velcro connector.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Hereinafter, exemplary embodiment of the present invention will be described with reference to the accompanying drawings. 
   The present invention relates to a velcro connector using a hook of a velcro tape attached to a garment, etc. and a loop coupled to the hook. 
   Herein, the velcro connector is largely sorted into a hook connector that is attached to the hook to transfer electric signals and a loop connector that is attached to the loop to transfer electric signals. At this time, the velcro connector has a structure where the hook connector and the loop connector are electrically connected to each other upon coupling the hook and the loop. 
   Hereinafter, a configuration according to the embodiment will be described with reference to  FIGS. 1 to 8 . 
   First,  FIG. 1  is a diagram showing a configuration of a hook connector of the velcro connector according to a first embodiment of the present invention. 
   Referring to  FIG. 1 , a hook connector  100  according to the present invention is one that a connector part  110  and a hook part  120  are coupled to each other. In an embodiment of  FIG. 1 , the connector part  110  and the hook part  120  are separately provided for convenience of explanation. However, the hook connector  100  may be one where the connector part  110  and the hook part  120  are integrally formed. 
   First, the connector part  110  in the hook connector  100  includes a hook connector body  111 , a hook connector connecting part  113 , a connecting terminal  115 , and a connecting line  117 . The hook connector connecting part  113 , the connecting terminal  115 , and the connecting line  117  are disposed on the hook connector body  111 . Further, the hook part  120  includes a hook body  121  and a hook  125  in a hook shape attached to the hook body. At this time, the hook part  120  is coupled to the lower portion of the hook connector body  111 . In the present embodiment, although the hook part  120  is described by sorting into the hook body  121  and the hook  125  for convenience sake, the coupling form of the hook  125  and the hook body  121 , that is, the hook part  120  itself may be called a hook. 
   The hook connector connecting part  113  is disposed in a predetermined area of the hook connector body  111 . At this time, the hook connector connecting part  113  may be provided in plurality. Further, the hook connector connecting part  113  is electrically connected to the connecting terminal  115  to transfer the electric signals input through the connection terminal  115  to the loop connector or to output the electric signals applied from the loop connector to the outside through the connecting terminal  115 . 
   At this time, the hook connector connecting part  113  is directly or indirectly connected to the connecting terminal  115 . In the case of an indirect connection, they can be connected to each other by the connecting line  117 . The connecting line  117  is a line that connects the hook connector connecting part  113  to the connecting terminal  115  and can be implemented by a yarn composed of a conductive material. 
   Meanwhile, the hook connector connecting part  113  can be implemented as a pad made of a conductive material, otherwise implemented using a non-conductive material in the case of using a separate first signal connecting means. Further, in the case of using the separate first signal connecting means, the hook body  121  can be formed with a hole  123  for inserting the first signal connecting means coupled by the hook connector connecting part  113 . At this time, the shape and size of the hole  123  formed on the hook body  121  can be changed according to the connecting portion with the loop connector and omitted according to the connecting position. Therefore, the first signal connecting means contacts the loop connector through the hole on the hook body  121 . The embodiment of the first signal connecting means will be described with reference to  FIG. 3 . 
   The connecting terminal  115  is a terminal connected to the external electric line and is implemented in the pad form of the conductive material and can thus be attached to the hook connector body  111 . At this time, it is preferable that the connecting terminal  115  is disposed at the end of the hook connector body  111  so that it is easily connected to the external line. Of course, the state that the connecting terminal  115  is disposed only in one direction is shown in the drawing, but the embodiment is not limited thereto. Further, the connecting terminal  115  can also be disposed in two directions or in any direction. Therefore, the connecting terminal  115  of the corresponding hook connector  100  is connected to the connecting terminal of another hook connector by the external electric line, making it possible to connect the plurality of hook connectors  100  in series. Meanwhile, the connecting terminal  115  may be connected to a separately provided circuit module. 
     FIG. 2  shows a diagram showing a configuration of a loop connector of a velcro connector according to the present invention. Referring to  FIG. 2 , a loop connector  200  according to the present invention is one when a connector part  210  and a loop part  220  are coupled to each other. In an embodiment of  FIG. 2 , the connector part  210  and the look part  220  are separately provided for convenience of description. However, the looP connector  200  may be one when the connector part  210  and the hook part  220  are integrally formed. 
   First, the connector part  210  in the hook connector  200  includes a loop connector body  211 , a loop connector connecting part  213 , a connecting terminal  215 , and a connecting line  217 . The loop connector connecting part  213 , the connecting terminal  215 , and the connecting line  217  are disposed on the loop connector body  211 . Further, the loop part  220  includes a loop body  221  and a loop  225  attached to the loop body  221  and coupled to the hook  125 . At this time, the loop part  220  is coupled to the upper portion of the hook connector body  211 . In the present embodiment, although the loop part  220  is described by sorting into the loop body  221  and the loop  225  for convenience sake, the coupling form of the loop  225  and the loop body  221 , that is, the loop part  220  itself may be called a loop. 
   The loop connector connecting part  213  is disposed in a predetermined area of the loop connector body  211 . At this time, the loop connector connecting part  213  may be provided in plurality. Further, the loop connector connecting part  213  is electrically connected to the connecting terminal  215  to transfer the electric signals input through the connection terminal  215  to the hook connector  100  or to output the electric signals applied from the hook connector  100  to the outside through the connecting terminal  215 . 
   At this time, the loop connector connecting part  213  is directly or indirectly connected to the connecting terminal  215 . In the case of indirect connection, they are connected to each other by the connecting line  217 . The connecting line  217  is a line that connects the loop connector connecting part  213  to the connecting terminal  215  and can be implemented by yarn made of a conductive material. 
   Meanwhile, the loop connector connecting part  213  can be implemented as a pad made of a conductive material or a non-conductive material in the case of using a separate second signal connecting means. Further, in the case of using the separate second signal connecting means, the loop body  221  can be formed with a hole  223  for inserting the second signal connecting means coupled the loop connector connecting part  213 . At this time, the shape and size of the hole  223  formed on the loop body  221  can be changed according to the connecting portion of the second signal connecting means and omitted according to the connecting position. Therefore, the second signal connecting means contacts the hook connector  100  through the hole on the hook body  121 . 
   The second signal connecting means can be implemented in a conductive loop form as shown in  FIG. 2  and the conductive loop may be provided in a form attached to the upper portion of the loop connector connecting part  213 . Meanwhile, the second signal connecting means may be inserted and coupled in the loop connector connecting part  213  in a vertical direction. At this time, the second signal connecting means can be integrally connected with the loop connector body  213 . 
   The connecting terminal  225  is a terminal connected to the external electric line and is implemented as the pad made of the conductive material and can thus be attached to the loop connector body  211 . At this time, it is preferable that the connecting terminal  215  is disposed at the end of the loop connector body  211  so that it is easily connected to the external line. In an embodiment of  FIG. 2 , a direction where the connecting terminal  215  is provided is formed in the same direction as the connecting terminal  115  of the hook connector  100  of  FIG. 1  to more easily describe the embodiment according to the present invention. However, in order to increase the efficiency of the connector, the connecting terminal  215  may be formed in an opposite direction to the connecting terminal  115  of the hook connector  100 . 
   Also, the state that the connecting terminal  215  is disposed only in one direction is shown in the drawing, but the embodiment is not limited thereto. Further, the connecting terminal  215  can also be disposed in two directions or any direction. Therefore, the connecting terminal  215  of the corresponding loop connector  200  is connected to the connecting terminal of another loop connector by the external electric line, making it possible to connect the plurality of loop connectors  200  in series. Meanwhile, the connecting terminal  215  may be connected to a separately provided circuit module. 
     FIG. 3  shows an embodiment of the hook connector of the present invention. In detail,  FIG. 3  shows an example that implements the different embodiment of the first signal connecting means in the hook connector. 
   First, in a hook connector  100   a  shown in  FIG. 3(   a ), the hook connector connecting part  113  is provided with a first signal connecting means  113   a , such as a button, a pin, etc. made of a conductive material, which is formed in a ‘T’-letter shape. At this time, the first signal connecting means  113   a  may be integrally with the hook connector body  111  and inserted and coupled in the hook connector body  111  in a vertical direction. 
   Herein, the first signal connecting means  113   a  can be variously implemented to have a length of a predetermined value or more in a vertical direction the hook connector body  111  in ‘I’-letter shape, ‘           ’-letter shape, etc. in addition to the ‘T’-letter shape. Therefore, the first signal connecting means  113   a  contacts the second signal connecting means of the loop connector  200  upon coupling the hook  125  and the loop  225 .
   At this time, the first signal connecting means  113   a  is electrically connected to the connecting terminal  115  through the connecting line  117  and transfers the electric signals input through the connecting terminal  115  to the loop connector  200  or transfers the electric signals applied from the loop connector  200  to the connecting terminal  115 . Of course, the first signal connecting means  113   a  man be directly connected to the connecting line  117  or may be connected to the connecting line  117  through the hook connector connecting part  113 . 
   Meanwhile, a hook connector  110   b  shown in  FIG. 3(   b ) includes the conductive hook as the first signal connecting means  113   b , such that the hook connector  100   b  and the loop connector  200  can be electrically connected to each other upon coupling the hook and the loop. In other words, when coupling the hook  125  and the loop  225 , the conductive hook is coupled to the second signal connecting means of the loop connector  200 , that is, the conductive loop, such that the hoop connector  100   b  and the loop connector  200  are electrically connected to each other. 
   As such, the hook connector includes the first signal connecting means  113   a  and  113   b , such that the hook connector and the loop connector can be more firmly connected. Also, even though the conductive hook or the conductive loop are not weaved together using the conductive yarn when manufacturing the velcro tape, the electric signals can be transferred between the hook connector and the loop connector by inserting a metallic pin, etc. after being manufactured. 
     FIG. 4  shows a configuration of the hook connector of the velcro connector according to a second embodiment, wherein the first signal connecting means is formed to be removable to the hook connector body. 
     FIG. 4  shows an example that a first signal connecting means  319  uses a hook composed of a conductive material, but as shown in  FIG. 3 , the first signal connecting means  319  can be variously implemented to have a length of a predetermined value or more in a vertical direction of the hook connector body  311 , such as a button, a pin, etc. of a conductive material formed in a ‘T’-letter shape. 
   The hook connector connecting part  313  is formed as a groove to open one side thereof and a side end of the groove may be formed as a groove (not shown) or a protrusion (not shown) to facilitate the mounting of the first signal connecting means. Therefore, the first signal connecting means  319  can be detached and attached from and to the hook connector connecting part  313  in a horizontal direction. At this time, when the first signal connecting means  319  is mounted on the hook connector connecting part  313 , the connecting terminal  315  is electrically connected to the first signal connecting means  319  by the connecting line  317 . 
   The so formed connector part  310  is coupled to the hook part  320 , thereby completing the hook connector  300  in another form. At this time, the first signal connecting means  319  is coupled to be protruded to the hook connector body  311 . 
     FIG. 5  shows a configuration of the loop connector of the velcro connector according to the second embodiment and shows the loop connector for coupling with the hook connector of  FIG. 4 . 
   A loop connector  400  separately includes a second signal connecting means  419  coupled to the first signal connecting means  319  of the hook connector  300  similar to the embodiment of  FIG. 4 , such that it is formed to be removable from a loop connector connecting unit  413  of a loop connector body  411 . At this time,  FIG. 5  shows an example that the conductive loop for coupling with the conductive hook used as the first signal connecting means  319  of  FIG. 4  is used as the second signal connecting means  419 , but it may use a means corresponding to the implementation form of the first signal connecting means  319  of  FIG. 4 . 
   In  FIG. 5 , the hook connector connecting part  413  is formed as a groove to open one side thereof and a side end of the groove may be formed with a groove (not shown) or a protrusion (not shown) to facilitate the mounting of the second signal connecting means  419 . Therefore, the second signal connecting means  419  can be detached and attached from and to the loop connector connecting part  413  in a horizontal direction. At this time, when the second signal connecting means  419  is mounted on the loop connector connecting part  413 , the connecting terminal  415  is electrically connected to the second signal connecting means  419  by the connecting line  417 . 
   The so formed connector part  410  is attached to the loop part  420 , thereby completing the loop connector  400  in another form. At this time, the second signal connecting means  419  is coupled to be protruded to the loop connector body  411 . 
   Consequently, when coupling the hook and the loop of the velcro connector, the conductive hook is mounted so as to protrude on the hook connector body  311  and the conductive loop is also mounted so as to protrude on the loop connector body  411  are coupled to each other, thereby transferring the electric signals between the hook connector  300  and the loop connector  400  therethrough. 
     FIG. 6  is a diagram showing a configuration of the hook connector of the velcro connector according to a third embodiment of the present invention. 
   Referring to  FIG. 6 , a hook connector  500  according to the present invention is one when a connector part  510  and a hook part  520  are coupled to each other. In an embodiment of  FIG. 6 , the connector part  510  and the hook part  520  are separately provided for convenience of description. However, the hook connector  500  may be one when the connector part  510  and the hook part  520  are integrally formed. 
   First, the connector part  510  in the hook connector  500  includes a hook connector body  511 , a hook connector connecting part  513 , a connecting terminal  515 , and a connecting line  517 . The hook connector connecting part  513 , the connecting terminal  515 , and the connecting line  517  are disposed on the hook connector body  511 . 
   The hook connector connecting part  513  is disposed in a predetermined area of the hook connector body  511 . At this time, the hook connector connecting part  513  may be provided in plurality. Further, the hook connector connecting part  513  is electrically connected to the connecting terminal  515  to transfer the electric signals input through the connection terminal  515  to the loop connector or to output the electric signals applied from the loop connector to the outside through the connecting terminal  515 . 
   At this time, the hook connector connecting part  513  is directly or indirectly connected to the connecting terminal  515 . In the case of indirect connection, they are connected to each other by the connecting line  517 . The connecting line  517  is a line that connects the hook connector connecting part  513  to the connecting terminal  515  and can be implemented by yarn made of a conductive material. At this time, the hook connector connecting part  513  can be implemented as a pad made of a conductive material. 
   The connecting terminal  515  is a terminal connected to the external electric line and is implemented as a pad made of a conductive material and can thus be attached to the hook connected body  511 . At this time, it is preferable that the connecting terminal  515  is disposed at the end of the hook connector body  511  so that it is easily connected to the external line. Of course, the state that the connecting terminal  515  is disposed only in one direction is shown in the drawing, but the embodiment is not limited thereto. Therefore, the connecting terminal  515  can further be disposed in two directions or any direction. Therefore, the connecting terminal  515  of the hook connector  500  is connected to the connecting terminal of another hook connector by the external electric line, making it possible to connect the plurality of hook connectors  500  in series. Meanwhile, the connecting terminal  515  may be connected to a separately provided circuit module. 
   The hook part  520  includes a hook body  521  and a hook  525  in a hook shape attached to the hook body. At this time, the hook part  520  is coupled to the lower portion of the hook connector body  511 . 
   Meanwhile, in the hook body  521 , the conductive pad  523  is provided at a position corresponding to the hook connector connecting part  513  of the connector part  510  and the conductive hook is attached to the lower portion of the conductive pad  523 . At this time, the conductive hook is electrically connected to the loop connector connecting part of the loop connector. Therefore, the conductive pad  523  contacts the hook connector connecting part  513  upon coupling the connector part  510  and the hook part  520  to transfer the electric signals input through the connecting terminal  515  to the loop connector through the conductive hook. Likewise, the electric signals input through the loop connector are transferred to the hook connector connecting part  513  through the conductive hook and the conductive pad  523  of the hook body  521 . 
     FIG. 7  is a diagram showing a configuration of a loop connector of a velcro connector according to a third embodiment of the present invention. 
   Referring to  FIG. 7 , a hook connector  600  according to the present invention is one when a connector part  610  and a loop part  620  are coupled to each other. In an embodiment  FIG. 7 , the connector part  610  and the loop part  620  are separately provided for convenience of description. However, the loop connector  600  may be one when the connector part  610  and the loop part  620  are integrally formed. 
   First, the connector part  610  in the loop connector  600  includes a loop connector body  611 , a loop connector connecting part  613 , a connecting terminal  615 , and a connecting line  617 . The loop connector connecting part  613 , the connecting terminal  615 , and the connecting line  617  are disposed on the loop connector body  611 . 
   The loop connector connecting part  613  is disposed in a predetermined area of the loop connector body  611 . At this time, the loop connector connecting part  613  may be provided in plurality. Further, the loop connector connecting part  613  is electrically connected to the connecting terminal  615  to transfer the electric signals input through the connection terminal  615  to the hook connector  500  or to output the electric signals applied from the hook connector  500  to the outside through the connecting terminal  615 . 
   At this time, the loop connector connecting part  613  is directly or indirectly connected to the connecting terminal  615 . In the case of indirect connection, they are connected to each other by the connecting line  617 . The connecting line  617  is a line that connects the loop connector connecting part  613  to the connecting terminal  615  and can be implemented by a yarn composed of a conductive material, etc. At this time, the loop connector connecting part  613  can be implemented in a pad form of a conductive material. 
   The connecting terminal  615  is a terminal connected to the external electric line and is implemented in a pad form of a conductive material and can thus be attached to the loop connector body  611 . At this time, it is preferable that the connecting terminal  615  is disposed at the end of the loop connector body  611  so that it is easily connected to the external line. Of course, the connecting terminal  615  disposed only in one direction is shown in the drawing, but the embodiment is not limited thereto. Therefore, the connecting terminal  615  can also be disposed in two directions or any direction. Therefore, the connecting terminal  615  of the loop connector  600  is connected to the connecting terminal of another loop connector by the external electric line, making it possible to connect the plurality of loop connectors  600  in series. Meanwhile, the connecting terminal  615  may be connected to a separately provided circuit module. 
   The loop part  620  includes a loop body  621  and a loop  625  attached to the loop body  621  and coupled to the hook  525 . At this time, the loop part  620  is coupled to the upper portion of the loop connector body  611 . 
   Meanwhile, in the loop body  621 , the conductive pad is provided at a position corresponding to the loop connector connecting part  613  of the connector part  610  and the conductive loop  623  is attached to the upper portion of the conductive pad. At this time, the conductive loop is electrically connected to the conductive hook of the hook connector  500 . 
   Therefore, the conductive pad of the loop body  621  contacts the loop connector connecting part  613  upon coupling the connector part  610  and the loop part  620  to transfer the electric signals input through the connecting terminal  615  to the hook connector  500  through the conductive loop  623 . Likewise, the electric signals input through the hook connector  500  are transferred to the loop connector connecting part  613  through the conductive loop  623  and the conductive pad of the loop body  621 . 
     FIG. 8  is a diagram for explaining a configuration of the velcro connector according to one embodiment of the present invention and shows the separate circuit module connected to the hook connector. 
   In other words, the connecting terminal  115  of the hook connector  100  is connected to a separate circuit module  700  by the external electric line. Therefore, in the state when the hook  125  and the loop  225  of the velcro connector are coupled to each other, if the electric signals from the circuit module  700  connected to the hook connector  100  are input, the hook connector  100  transfers the electric signals input through the input terminal  115  to the loop connector connecting part  213  of the loop connector  200  through the hook connector connecting part  113 . At this time, the loop connector  200  outputs the electric signals applied to the loop connector connecting part  213  to the outside through the connecting terminal  215 . 
   In  FIG. 8 , an example that the circuit module  700  is connected to the hook connector  100  according to the first embodiment is described, but the circuit module can be connected to the hook connectors  300  and  500  according to the second embodiment and the third embodiment. Further, it is natural that the circuit module  700  may be connected to the loop connectors  200 ,  400 , and  600  according to the first embodiment, the second embodiment, and the third embodiment. 
   When the plurality of hook connectors  100  and loop connectors  200  are provided, the electric signals output from the loop connector  200  are input through the input terminal of other loop connectors and output to the outside through the hook connector electrically connected to the corresponding loop connector. Herein, the plurality of hook connectors  100  and loop connectors  200  are electrically connected to each other by embroidered yarn made of a conductive material. 
   At this time, when the velcro connector is generally attached to a garment, the hook is attached to one side and the loop is attached to the other side, thereby electrically connecting among the hook connectors and electrically connecting among the loop connectors. When the hook and the loop are alternately attached to one side, it is natural that the hook connector and the loop connector attached to one side can be electrically connected to each other. 
   Therefore, when the velcro connector according to the present invention is attached to a garment, etc., it is easy to couple and separate the velcro connector to and from a garment and the circuit module can be connected through the contacts of the velcro connector. Further, it is possible to effectively transfer the electric signals from the wearable computer, etc. As an example, there may be a case of electrically connecting electronic circuits mounted on a garment and electric circuits mounted on gloves, a case of electrically connecting each garment when a person wears several-layered garments, or a case of electrically connecting the existing PCB board to a garment. In addition to these, it can be implemented in various ways. 
   As described above, the velcro connecter according to the present invention is not limited to the configuration and method of the foregoing embodiments, but the embodiments may be configured by selectively combining all the embodiments or some of the embodiments so that various modifications can be made.
