DETAILED DESCRIPTION
Hereinafter reference will now be made in detail to various embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below. While the invention will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
A connector according to an embodiment of the present invention includes a female connector 100, a male connector 119, and a connector cover 111 for protecting and maintaining the connected state of the female connector 100 and the male connector 119.
The female connector 100 includes a terminal receiving portion 100a into which a plurality of terminals for transmitting and receiving signals are inserted and a housing 101 which is formed in an oval shape and surrounds the circumference of the terminal receiving portion 100a. 
The housing 101 includes a large diameter portion formed at the front thereof, in which the terminal receiving portion 100a is disposed in the inner portion thereof, and a small diameter portion formed at the rear portion thereof.
A rectangular projection 102 is formed on an upper end of the large diameter portion of the housing 101, a first guide groove 103 is formed on an upper wall of the projection 102 in the forward and backward direction, and a pair of second guide grooves 104 are formed on both side walls of the projection 102 in the forward and backward direction.
Here, the first guide groove 103 and the pair of second guide grooves 104 are arranged in parallel to each other. The first guide groove 103 guides the insertion of the connector cover 111 into the female connector 100 in the forward direction, and the second guide grooves 104 control the connector cover 111 to be pre-mounted on the female connector 100.
Moreover, a first locking projection 105 is formed at the rear of the first guide groove 103 on the upper surface of the projection 102, and a pair of second locking projections 106 are formed on both sides of the upper surface of the projection 102 in the width direction with the first guide groove 103 interposed therebetween.
Here, the first locking projection 105 and the pair of second locking projections 106 are arranged to form the apex of a triangle.
The housing 101 includes an operating lever 107 such that a user can push the operating lever 107 by hand to lock and unlock the female connector 100 and the male connector 119.
The operating lever 107 is horizontally disposed over the large and small diameter portions of the housing 101 in the forward and backward direction. The front portion of the operating lever 107, at which a locking projection 108a is provided, and the rear portion thereof, which is able to be pushed by hand, are configured to perform a seesaw motion with respect to a fulcrum 108 in the middle thereof.
The locking projection 108a at the front bottom of the operating lever 107 is used to maintain the connected state of the male connector 119 and the female connector 100.
An inner seal 109 of a flexible material (e.g., rubber) is inserted into the inside of the housing 101 to surround a portion of the terminal receiving portion 100a and maintain airtightness, and a front holder 110 is inserted between the bottom of the terminal receiving portion 100a and the bottom of the inner seal 109 to maintain the shape of the inner seal 109.
Here, the connector cover 111 is molded with ferrite powder, which is effective for removal of noise, and provided adjacent to the connector, a main source of noise. Therefore, the connector cover 111 can effectively remove/reduce the noise of the vehicle and further protect the connector from an external impact.
The connector cover 111 is mounted on the female connector 100 to surround the outer circumferential surface of the housing 101 of the female connector 100 and includes a body 112 for surrounding the circumferential surface of the large diameter portion of the housing 101 and a rectangular projection receiving portion 113 integrally formed on the top of the body 112 and surrounding the circumferential surface of the projection 102 of the housing 101.
A first through hole 114 is formed on the upper surface of the projection receiving portion 113 such that the first locking projection 105 of the female connector 100 is inserted and fixed thereto, and thereby it is possible to determine the mounting position of the connector cover 111.
A pair of second through holes 115 are formed in parallel to each other in the forward and backward direction with the first through hole 114 interposed therebetween to guide the movement of the connector cover 111 and prevent the connector cover 111 from being moved backward from the female connector 100.
Here, the first through hole 114 is formed to penetrate the upper surface of the projection receiving portion 113 with a size that can accommodate the first locking projection 105, and the second through holes 115 are formed to extend in the forward and backward direction such that the second locking projections 106 move within a predetermined distance in the forward and backward direction.
Moreover, a receiving groove 116 is formed in the inside of the upper end of the projection receiving portion 113 at the rear of the first through hole 114 and the second through holes 115 such that the first locking projection 105 and the second locking projections 106 can move therethrough.
A lever locking guide 117 is formed downward in the inside of the front end of the projection receiving portion 113 to be inserted into the first guide groove 103 when the connector cover 111 is pre-mounted on the housing 101 of the female connector 100. When the connector cover 111 is completely mounted on the female connector 100 as the lever locking guide 117 moves forward to the end of the first guide groove 103, the operating lever 107 of the female connector 100 cannot perform a seesaw motion and thereby the locked state of the female connector 100 and the male connector 119 is maintained.
A pair of cut projections 118 are formed on both side walls of the projection receiving portion 113 in the forward and backward direction, in which the front end of each cut projection 118 is integrally connected to the front end of the side wall of the projection receiving portion 113 and the remaining portion of the cut projection 118 is cut along the middle of the side wall of the projection receiving portion 113 in the forward and backward direction. Therefore, the cut projections 118 are elastically supported with respect to the front end thereof to be rotated or bent inward in the width direction of the projection receiving portion 113 such that the cut projections 118 are inserted into the second guide grooves 104 when the connector cover 111 is mounted on the housing 101 of the female connector 100.
The male connector 119 is inserted into the inside of the housing 101 of the female connector 100 and electrically connected to the female connector 100 such that the male and female connectors 119 and 100 can transmit and receive signals to and from each other.
A locking projection 121 is formed on an upper end of a housing 120 of the male connector 119. The locking projection 121 of the male connector 119 is connected to the locking projection 108a formed on the operating lever 107 of the female connector 100, and thereby the connected state of the male connector 119 and the female connector 100 can be maintained.
Moreover, a pair of guide rails 122 are formed in parallel to each other on an upper end of the housing 120 of the male connector 119. The guide rails 122 having a cross section of “” shape are inserted along the second guide grooves 104 formed on the projection 102 of the housing 101 of the female connector 100 such that the housing 120 of the male connector 119 is inserted into the inside of the housing 101 of the female connector 100 and connected thereto.
The use of the connector in accordance with an exemplary embodiment of the present invention having the above-described configuration will be described below.
First, the connector cover 111 is inserted into the outer circumferential surface of the female connector 100 to be pre-mounted thereto.
Here, a pre-mounting means for causing the connector cover 111 to be pre-mounted on the female connector 100 before the male connector 119 is inserted into the female connector 100 includes the second guide grooves 104 formed on both side walls of the projection 102 of the female connector 100, the second locking projections 106 formed to project from the upper end of the projection 102 of the female connector 100, the cut projections 118 formed on both side walls of the projection receiving portion 113 of the connector cover 111, and the second through holes 115 formed on the projection receiving portion 113 of the connector cover 111. Therefore, when the connector cover 111 is inserted into the outer circumferential surface of the female connector 100, the cut projections 118 are inserted into the second guide grooves 104 and stopped at the inner end of the second guide grooves 104 to prevent the connector cover 111 from further moving forward. Moreover, as the second locking projections 106 are inserted into the front ends of the second through holes 115, the connector cover 111 is prevented from moving backward.
Then, when the connector cover 111 is pre-mounted on the female connector 100, the male connector 119 is inserted and connected to the female connector 100.
A means for causing the male connector 119 to be inserted into the female connector 100 includes the guide rails 122 formed on the housing 120 of the male connector 119. When the guide rails 122 are inserted into the second guide grooves 104 of the female connector 100, the cut projections 118 of the connector cover 111 are pushed to the outside of the second guide grooves 104 such that the male connector 119 is inserted into the female connector 100.
A means for connecting and disconnecting the female connector 100 and the male connector 119 includes the operating lever 107 formed horizontally on the female connector 100, in which the front portion of the operating lever 107, at which the locking projection 108a is provided, and the rear portion thereof, which is able to be pushed by hand, perform a seesaw motion with respect to the fulcrum 108 in the middle thereof, and the locking projection 108a formed on the housing 120 of the male connector 119. When the male connector 119 is inserted into the inside of the female connector 100, the locking projection 121 of the male connector 119 raises the locking projection 108a of the operating lever 107 by the seesaw motion and then is connected to the locking projection 108a and, when the rear portion of the operating lever 107 is pushed, the front portion of the operating lever 107 is raised and then unlocked from the locking projection 121 of the male connector 119.
Then, the connector cover 111 is further moved forward to the female connector 100 to be double locked such that the connected state of the female connector 100 and the male connector 119 is maintained.
A means for maintaining the connected state of the locking projection 108a of the female connector 100 and the locking projection 121 of the male connector 119 and double locking the connected male and female connectors 119 and 100 includes the lever locking guide 117 formed on the upper end of the projection receiving portion 113 of the connector cover 111 and the first guide groove 103 formed on the upper end of the projection 102 of the female connector 100. When the connector cover 111 is moved forward as the cut projections 118 of the connector cover 111 are pushed to the outside of the second guide grooves 104 of the female connector 100 by the guide rails 122 of the male connector 119, the second locking projections 106 of the female connector 100 move along the second through holes 115 of the connector cover 111 to be positioned at the rear end of the second through holes 115. When the lever locking guide 117 moves forward along the first guide grove 103 to reach the inner end of first guide groove 103, the connector cover 111 does not move any further, and when the front portion of the operating lever 107 is positioned adjacent to the bottom of the lever locking guide 107, the operating lever 107 of the female connector 100 cannot perform a seesaw motion. As a result, the locking projection 121 of the male connector 119 cannot move backward by the locking projection 108a of the operating lever 107.
The position at which the connector cover 111 is mounted on the female connector 100 is determined by moving forward the connector cover 111 to the female connector 100.
When the connector cover 111 is moved forward, the first locking projection 105 formed on the projection 102 of the female connector 100 is inserted into the first through hole 114 formed on the projection receiving portion 113 of the connector cover 111, and thereby the user can determine the mounting position of the connector cover 111.
When the male connector 119 is connected to the female connector 100 in the above-described manner, the connector cover 111 can protect the connected state of the connector and further remove/reduce the electrical noise of the vehicle.
As described above, the connector in accordance with the present invention has the following advantages:
(1) Since the connector cover is molded with ferrite powder and installed adjacent to a noise source of the vehicle, it is possible to effectively remove/reduce the electrical noise;
(2) The female connector can be connected to and disconnected from the male connector using the operating lever; and
(3) The connector cover is movably mounted on the circumferential surface of the female connector in the forward and backward direction such that when the connector cover moves backward, the operation of the operating lever is stopped by the lever locking guide to main the connected state of the female connector and the male connector and, when the connector cover moves forward, the female connector can be disconnected from the male connector by the operation of the operating lever.
The invention has been described in detail with reference to preferred embodiments thereof. However, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
