The connector fixing member 180 is coupled to the USB connector 300 inserted in the USB port 102 to fix the USB connector 300 so as not to be detached.

6 and 7, the connector fixing member 180 includes a fixing portion 181 fixed to the substrate 130 and an elastic portion 181 extending downward at an oblique angle from one end of the fixing portion 181. [ A spike 183 protruding upward from the end of the elastic portion 182 and a stopper 187 protruding to the bottom surface of the fixing portion 181.

The connector fixing member 180 can be manufactured by machining a metal plate.

The fixing portion 181 of the connector fixing member 180 has a plurality of substrate coupling portions 185 protruded upward and the connector fixing member 180 is fixed to the substrate 130 by coupling the substrate coupling portion 185 to the substrate 130. [ And is mounted on the substrate 130.

Since the resilient portion 182 protrudes downward with respect to the fixed portion 181, the resilient portion 182 exhibits a restoring force downwardly when it is pushed upward. The spikes 183 protruding upward from the end of the elastic portion 182 are for coupling to the connector housing 310 of the USB connector 300 inserted into the USB port 102.

7 (a) shows a state in which the elastic portion 182 protrudes downward with respect to the fixing portion 181 because the force is not applied. This state is a state in which the contact between the cam 162 and the elastic portion 182 is released as the pressing member 160 rotates to the outside of the housing 101 as described later.

7B shows a state in which the elastic portion 182 is pushed up so that the spike 183 is coupled to the connector housing 310 of the USB connector 300. [ This state is a state in which the cam 162 is pushed up against the bottom surface of the elastic portion 182 as the pressing member 160 rotates in a direction to be inserted into the groove 122 of the housing 101 as described later.

The pressing member 160 is rotated in the direction in which the pressing member 160 is pulled out of the groove 122. Conversely, when the pressing member 160 is rotated in the direction of inserting the groove 122, a portion of the cam 162 that is larger than the radius of the rotating shaft 161 is positioned below the elastic portion 182 of the connector fixing member 180 Which causes the cam 162 to push up the resilient portion 182 upwardly.

Since the elastic portion 182 of the connector fixing member 180 is provided with the two stoppers 187 spaced apart in the width direction in the embodiment of the present invention, in order for the two stoppers 187 to stably ascend and descend at the same height, It is preferable that two or more cams 162 positioned at the lower portion of the rotary shaft 182 are also arranged in the longitudinal direction of the rotary shaft 161.

The accommodating portion 165 has an internal space 167 into which the urging member engaging portion 153 of the lock member 150 is inserted and the internal space 167 is located at the other end of the urging member 160, 161).

A guide groove 169 cut from the other end is formed in the ceiling of the receiving part 165 surrounding the inner space 167 and the guide groove 169 is formed in a position where the lock member 150 moves into the inside of the housing 101 The stopper engaging portion 155 is inserted.

The rotation shaft 161 of the urging member 160 is positioned below the spike 183 in order to push up the spike 183 of the connector fixing member 180 upward and the cam 161 162). However, the present invention is not limited to this. The rotating shaft 161 may be moved to one side of the spike 183, and the elastic portion 182 of the connector fixing member 180 may be connected to the connecting portion 164 of the pressing member 160, (Not shown in the figure) for pushing up the bottom surface of the base plate. In this case, when the pressing member 160 is rotated, the contact protrusions formed on the connecting portion 164 are raised, and the elastic portion 182 can be pushed up, so that the connector locking effect can be obtained in the same manner.

The pressing member engaging portion 153 is a portion that is inserted into the receiving portion 165 of the pressing member 160 and is provided at the rear end of the pressing member engaging portion 153 so as not to enter the receiving portion 165 An engaging wall 1532 for blocking can be formed.

A guide groove 1551 having a substantially rectangular shape is formed on the upper surface of the stopper engaging portion 155 along the moving direction of the lock member 150. A stopper 187 Is inserted.

The leading end wall of the guide groove 1551 becomes the first latching jaw 158 at which the lower end of the stopper 187 is hooked when the locking member 150 moves backward.

The distal end wall of the key groove 1551 becomes a second locking protrusion 159 which is engaged with the lower end of the stopper 187 when the locking member 150 is moved forward.

14, when the lock member 150 is moved to the outside of the housing 101, the stopper 187 of the connector fixing member 180 inserted into the guide groove 1551 on the upper surface is engaged with the first engaging jaw Lt; / RTI > In this state, the locking member 150 is no longer moved backward, so that the locking member 150 is not removed from the housing 101. [

15, the stopper 187 of the connector fixing member 180 inserted into the guide groove 1551 on the upper surface is inserted into the guide groove 1551 when the lock member 150 is pushed into the inside of the housing 101. Further, And is lifted upwards by the rear end wall. The lower end of the stopper 187 moves downward due to the restoring force when the stopper 187 passes the end wall of the key groove 1511, that is, the second stopping protrusion 159, 2 engaging jaws 159 in the direction of the arrow.

In this state, since the locking member 150 is almost inserted into the housing 101, it is almost impossible to forcibly pull out the locking member 150. Even if the locking member 150 is forcibly pulled, (159).

The wedge portion 220 is pushed into the keyhole 156 until the lower end of the stopper 187 is pushed up to a position higher than the second latching jaw 159, The locking member 150 can be pulled backward by inserting the coupling protrusion 212 of the locking member 200 into the coupling groove 1513. [

The cover 152 is formed with a stopper guiding portion 1525 cut from the front end to the rear side and a second locking protrusion 159 is positioned below the stopper guiding portion 1525. The pattern protrusion 154 contacting the stopper 187 when the stopper 187 moves in the pattern protrusion 154 exposed by the stopper guide 1525 should be formed to have a length that does not interfere with the movement of the stopper 187, And an inclined surface corresponding to the inclination of the inclined surface 187.

16 and 17 show the positions of the locking member 150 and the pressing member 160 when the locking member 150 is moved backward and when the locking member 150 is pushed forward.

Since the pressing member engaging portion 153 is not inserted into the receiving portion 165 when the locking member 150 is moved backward, it is possible to rotate the pressing member 160 around the rotating shaft 161. [

On the other hand, when the lock member 150 is moved forward, since the pressing member engaging portion 153 is inserted into the receiving portion 165, it is impossible to rotate the pressing member 160 about the rotating shaft 161. [ The spikes 183 pushed up by the cam 162 of the pressing member 160 are maintained in the state of being coupled to the connector housing 310 of the USB connector 300 so that the key unit 200 is not used The USB connector 300 can not be removed.

Referring again to FIGS. 12 and 13, a release preventing protrusion 157 is formed on both sides of the lock member 150, respectively. The tip of the release preventing protrusion 157 is engaged with the pressing member engaging portion 153 and a gap 1574 is formed between the release preventing protrusion 157 and the side surface of the base 151. Therefore, when the release preventing protrusion 157 is pushed toward the side surface of the base 151, the release preventing protrusion 157 exerts an elastic force toward the outside.

The protrusion 1572 protrudes outward beyond the side surface of the base 151 in a state where no force is applied to the detachment protrusion 157. The protrusion 1572 protrudes outward beyond the side surface of the base 151, The protrusion 1572 moves to the inside of the base 151 or the inside of the base 151 while the release preventing protrusion 1572 is slid downward.

The side surface of the projection 1572 is formed to have a slope with respect to the plane. That is, the side surface of the protrusion 1572 protrudes further toward the rear end side where the keyhole 156 is formed.

It is very easy to attach the locking member 150 to the housing 101 and prevent the locking member 150 from being detached once it is mounted on the housing 101 It plays a role.

14, when the locking member 150 is pushed through the hole formed in the lower cover 120 of the housing 101, the inclined surface of the protrusion 1572 of the detachment prevention protrusion 157 is inclined in the direction of the hole When the protrusion 1572 comes in contact with the edge and then passes through the hole, the elastic force causes the protrusion 1572 to expand to its original position.

The rear end of the protrusion 1572 is caught by the inner wall of the lower cover 120 as shown in the drawing, and it is no longer possible to pull the protrusion 1572 out of the housing 101.

The tensioner 170 is symmetrically disposed on both sides of the USB terminal block 140 to support the USB connector 300 inserted into the USB port 102. [ In the embodiment of the present invention, the tensioner 170 is coupled to the bottom surface of the upper cover 110 as shown in FIG. Or alternatively may be coupled to the substrate 130.

19, each tensioner 170 includes a fixing portion 171 coupled to the upper cover 110 or the substrate 130, a support portion 177 serving to support the USB connector 300, And an elastic connecting portion 175 connecting the fixing portion 171 and the supporting portion 177.

A coupling hole 172 is formed in the fixing portion 171 and a coupling protrusion formed in the upper cover 110 or the substrate 130 is inserted into the coupling hole 172.

The supporting portion 177 applies a predetermined pressure to the side surface of the connector housing 310 of the USB connector 300 to support the USB connector 300 in a horizontal direction. When the connector housing 310 is thin, it may be positioned on the upper surface of the connector housing 310 to support the USB connector 300 from being shaken in the vertical direction.

At an end of the support portion 177, an inclined surface 179 for guiding the movement of the connector housing 310 is formed.

20, when the connector housing 310 enters between the pair of tensioners 170 facing each other, the connector housing 310 is guided through the inclined surfaces 179 of the both tensioners 170, Position. Further, as the connector housing 310 enters, the supporting portions 177 on both sides spread apart to apply a constant pressure to both sides of the connector housing 310.

On the other hand, as shown in FIGS. 21 and 22, part of the USB connector 300 may be omitted, and the overall thickness of the connector housing 350 may be thinner than that of the standard connector. When such a connector housing 350 is inserted, the tensioner 170 may serve to prevent shaking by pressing or supporting the upper end of the connector housing 350 at the upper portion of the connector housing 350.

Hereinafter, a method of fixing the USB connector 300 in the hub 100 according to an embodiment of the present invention will be described with reference to FIGS. 23 to 26. FIG.

First, as shown in Fig. 23, the pressing member 160 is rotated downward (the outer side of the housing) to lower the spikes 183 of the connector fixing member 180, It should be moved backward as shown.

When the USB connector 300 is inserted into the USB port 102 in this state, the USB terminal block 140 is inserted into the connector housing 310 as shown in FIG.

25, when the pressing member 160 is rotated to the upper side (the housing side), the cam 162 formed on the rotating shaft 161 of the pressing member 160 rotates the connector fixing member 180 The spike 183 moves upward.

The spikes 183 maximally lifted by the cams 162 are inserted into the housing holes 320 provided in the connector housing 310 of the USB connector 300 when the pressing members 160 are completely rotated and inserted into the grooves 122. [ And if the terminal block is made of plastic, the spike 183 is stuck to the terminal block.

26, when the lock member 150 is pushed toward the inside of the housing 101, the pressing member engaging portion 153 of the lock member 150 is pressed against the pressing member 160 as shown in Fig. 17, As shown in FIG.

In this state, the pushing member 160 can not be rotated downward unless the lock member 150 is retracted, so that the USB connector 300 can not be pulled out due to the spike 183 of the connector fixing member 180.

15, when the lock member 150 is pushed toward the inside of the housing 101, the stopper 187 of the connector fixing member 180 is brought into contact with the second latching jaw 159 of the lock member 150 The locking member 150 can not be retracted.

Therefore, in order to remove the USB connector 300, the lock member 150 must be moved backward by using the key unit 200 as shown in FIG.

The key unit 200 includes a key 210 protruding in parallel to the front of the housing and a wedge part 220 movably coupled to the housing. The key 210 has one end thereof directed to the outside of the housing Or a pair of protruding protrusions. The key 210 includes a coupling protrusion 212 protruding outward in the vicinity of the tip end and the coupling protrusion 212 is inserted into a coupling groove 1513 formed in the keyhole 156 of the lock member 150 Section.

The wedge part 220 moves in the forward and backward direction by the sliding button 230 provided in the housing and supports the key 210 to prevent the keys 210 from moving toward each other do. A pattern groove 222 is formed at the tip of the wedge 220 in the longitudinal direction and the pattern groove 222 is a portion into which the pattern protrusion 154 formed in the lock member 150 is inserted. If the number and size of the pattern groove portion 222 and the pattern protruding portion 154 are varied, the locking member 150 can be pulled out only by using the key unit 200, which is precisely matched with the pattern groove portion 222 and the pattern protruding portion 154,

Meanwhile, since the specific operation principle of the key unit 200 and various modified examples are described in the applicant's registered patent No. 10-1579470, the same will be referred to in this specification.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

For example, in the above-described embodiment, the pressing member 160 is rotatably coupled to the bottom surface of the housing 101 using the rotation shaft 161, but the pressing member 160 may be configured differently. That is, as in the case of the secure USB hub 100a shown in Figs. 28 and 29, the pressing member 160 may be installed to move up and down with respect to the housing 101. [

At this time, it is also possible to use a spring or the like so that the pressing member 160 always receives the elastic force toward the outside of the housing 101. In this case, if the force is not applied, the pressing member 160 protrudes out of the lower cover 120 as shown in FIG. 28, and when the force is applied, the pressing member 160 can enter the inside as shown in FIG.

The pressing member 160 shown in Figs. 28 and 29 does not include the rotating shaft, but the holding member 160 having the internal space 167 opened in the direction in which the lock member 150 is inserted (as shown in Figs. 10 and 11) 165). Further, the pressing member 160 may be provided with contact protrusions or the like capable of pushing the elastic portion 182 of the connector fixing member 180 more effectively.

The pressing member 160 should be installed so as to rise up to a height corresponding to the receiving portion 165 of the locking member 150. When the pressing member 160 is pushed up and the locking member 150 is advanced, It is locked.

28 to 30 show a structure in which the pressing member 160 is installed so as to be able to move up and down from the lower portion of the connector fixing member 180. Alternatively, It may be configured to move. For example, when the pressing member 160 is horizontally moved in one direction, it enters the lower portion of the elastic portion 182 to push up the elastic portion 182, and when the pressing member 160 is horizontally moved in the opposite direction, The elastic portion 182 may be lowered. Here, the horizontal direction may be a direction approximately parallel to the substrate 130.

As another example, in the above-described embodiment, the locking member 150 is inserted from one side of the housing 101 to be coupled with the pressing member 160 to block the rotation or movement of the pressing member 160. A locking structure for fixing the pressing member 160 to the housing 101 may be provided in the pressing member 160 or the housing 101 instead of the locking member 150 having the structure described in this specification. In this case, when the lock is released using the key, the pressing member 160 can be rotated, lowered, or horizontally moved. In addition, it is possible to block the movement of the pressing member 160 by applying various locking structures.

As another example, in the embodiment of the present invention, the stopper 187 extending downward from the fixing portion 181 of the connector fixing member 180 is formed to prevent the locking member 150 from moving backward, The stopper 187 does not necessarily have to be formed on the connector fixing member 180. That is, the shape and position of the connector fixing member 180 may be changed, and a stopper 187 capable of engaging with the lock member 150 may be formed on a structure other than the connector fixing member 180.

As another example, in the embodiment of the present invention, the lock member 150 pushed into the housing 101 can be pulled back by using the key unit 200. However, the key hole 156 may be omitted So that it can be configured so that it can not be removed permanently once it is installed.

As another example, in the embodiment of the present invention, the tensioner 170 is installed to support the USB connector 300 inserted into the USB port 102, but the tensioner 170 may be omitted or replaced by another structure have.

As another example, in the embodiment of the present invention, the release preventing protrusions 157 are formed on both sides of the lock member 150, but the release preventing protrusions 157 may be omitted.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, to be.
