As referred to herein, a hybrid vehicle is a vehicle that has two or more sources of power, for example both gasoline-powered and electric-powered vehicles.

(15) Referring now to the disclosed embodiments, a high voltage connector for a vehicle according to the present disclosure is configured to include a first connector 100 including an interlock switch part 110 and a second connector 200 pressing the interlock switch part 110 to control opening or closing of a high voltage transfer of the interlock switch part 110, as illustrated in FIGS. 1 to 8.

(16) As illustrated in FIGS. 1 and 2, the first connector 100 is connected to a first wire inserted from the outside so as to transfer a current and configuring an interlock circuit to transfer the current, and includes the interlock switch part 110 discriminating an interlock signal to open or close a voltage transfer.

(17) As illustrated in FIGS. 1 and 7, the second connector 200 is connected to a second wire inserted from the outside so as to transfer a current to transfer the current, and includes a pressing part 210 pressing a portion of the interlock switch part 110 of the first connector 100 to control the opening or closing of the voltage transfer of the interlock switch part 110. That is, the first connector 100 is a male connector, the second connector 200 is a female connector, and the first and second connectors 100 and 200 may be connected to each other.

(18) As illustrated in FIGS. 2 and 4, the first connector 100 includes a first current terminal 121 and a second current terminal 122 that are disposed in a housing and transfer a large current. The large current transferred through the first and second current terminals 121 and 122 is not a current transferred from the first wire, but is a large current transferred from the second connector 200. Meanwhile, the large current may also be transferred from the first connector 100 including an interlock switch to the second connector 200.

(19) The interlock switch part 110 is provided between the first and second current terminals 121 and 122 of the first connector 100, thereby making it possible to turn on/off an interlock system in a circuit form at the time of connecting the first and second connectors 100 and 200 to each other.

(20) As illustrated in FIGS. 1, 7, and 8, the second connector 200 includes a first current connecting bar 221 and a second current connecting bar 222 contacting the first current terminal 121 and the second current terminal 122 formed in the first connector 100, thereby enabling the first connector 100 to transfer a current of the second connector 200 at the time of connecting the first connector 100 and the second connector 200 to each other.

(21) Meanwhile, as illustrated in FIGS. 2, 4, and 5, the interlock switch part 110, which turns on/off the interlock system at the time of connecting the first connector 100 and the second connector 200 to each other, is configured to include a switch body 111 provided in the first connector 100 and connected to the first wire, a switch rod 112 provided at a front end of the switch body 111 so as to be movable by the pressing part 210 of the second connector 200, and a coil spring 113 connecting the switch body 111 and the switch rod 112 to each other.

(22) Here, the front end of the switch body 111 is provided with an interlock terminal 114 transferring a voltage of the first wire and a rear end of the switch rod 112 is provided with a short spring terminal 115 into which the interlock terminal 114 is selectively inserted, such that the interlock circuit is not operated in the case in which the interlock terminal 114 is inserted into the short spring terminal 115 and the interlock circuit is operated in the case in which the interlock terminal 114 is not inserted into the short spring terminal 115.

(23) In addition, it is preferable that a catching groove 211 is formed in the pressing part 210 to correspond to the switch rod 112. That is, when the first connector 100 and the second connector 200 are connected to each other, the pressing part 210 presses the switch rod 112 while the second connector 200 is inserted onto the first connector 100, thereby moving the switch rod 112. Therefore, the interlock terminal 114 is inserted into the short spring terminal 115 provided at the rear end of the switch rod 112, such that the interlock circuit is not operated. To the contrary, when the first connector 100 and the second connector 200 are disconnected from each other, the short spring terminal 115 is also disconnected from the interlock terminal 114, such that the interlock circuit is operated.

(24) Meanwhile, as illustrated in FIG. 3, the short spring terminal 115 has a shape of a leaf spring folded to have a predetermined gap, one end of the short spring terminal is fixed to the switch rod 112, and the other end thereof is opened to correspond to the interlock terminal 114, thereby making it possible to connect the interlock circuit by spring tension at the time of contacting the interlock terminal 114. In addition, a catching part 116 is formed at a folded portion of the short spring terminal 115 to prevent the short spring terminal 115 from being separated from the switch rod 112.

(25) Meanwhile, as another example of the short spring terminal 115, as illustrated in FIG. 6, the short spring terminal 115 is a female terminal including a spring part 118 elastically contacting the interlock terminal 114 so as to correspond to the interlock terminal 114, a deformation preventing part 119 preventing deformation of the spring part 118, and a cover 117 formed outside the spring part 118 so as to protect the spring part 118 and having a box structure in which the spring part 118, the deformation preventing part 119, and the cover 117 are formed integrally with each other by repeatedly performing cutting and bending processes on a member having a plate shape several times.

(26) The cover 117 is formed by repeatedly performing the cutting and bending processes on the member having the plate shape several times, and a catching part for preventing the cover 117 from being separated from the switch rod 112 is formed in the cover 117. In addition, the short spring terminal 115 prevents deformation of a spring, thereby making it possible to improve electrical and mechanical contact stability of the interlock system.

(27) An operation sequence of the interlock system depending on connection between the first connector 100 and the second connector 200 in the present disclosure will be described. As illustrated in FIGS. 9 and 10, first (i.e., upper-left), a connection between the first connector 100 and the second connector 200 is prepared. In this case, the first current terminal 121 and the second current terminal 122 of the first connector 100 do not contact the first current connecting bar 221 and the second current connecting bar 222 of the second connector 200. Thus, an interlock contact is not made, such that the first connector 100 and the second connector 200 are in a high voltage and non-conducting state. Second (i.e., upper-right), when the second connector 200 are further connected to the first connector 100, the first current terminal 121 and the second current terminal 122 of the first connector 100 and the first current connecting bar 221 and the second current connecting bar 222 of the second connector 200 contact each other, but the interlock contact is not made, such that the first connector 100 and the second connector 200 are in the high voltage and non-conducting state. Third (i.e., lower-right), when the second connector 200 is further connected to the first connector 100, the first current terminal 121 and the second current terminal 122 of the first connector 100 and the first current connecting bar 221 and the second current connecting bar 222 of the second connector 200 completely contact each other, and the switch rod 112 and the pressing part 210 contact each other, such that high voltage conduction is prepared. Fourth (i.e., lower-left), when the second connector 200 is further connected to the first connector 100, the pressing part 210 presses the switch rod 112 in a state in which the first current terminal 121 and the second current terminal 122 of the first connector 100 and the first current connecting bar 221 and the second current connecting bar 222 of the second connector 200 completely contact each other, such that the interlock terminal 114 and the short spring terminal 115 are coupled to each other, thereby starting the high voltage conduction.

(28) As described above, the high voltage connector for a vehicle according to the present disclosure includes the first connector 100 including the first current terminal 121 and the second current terminal 122 serving as a path of the current and the second connector 200 including the first current connecting bar 221 and the second current connecting bar 222 connected to the first current terminal 121 and the second current terminal 122, detachably connected to the first connector 100, and including the pressing part 210 protruding toward the first connector 100. The first connector 100 is provided with the interlock switch part 110 formed between the first current terminal 121 and the second current terminal 122 and moving by the pressing part 210 to open or close the voltage transfer of the first current terminal 121 and the second current terminal 122.

(29) Therefore, the size, volume, and weight of the connector can be decreased. Because the decreased spatial margin is provided at the time of designing a vehicle package, marketability of the connector is improved. Further, a contact of the interlock terminal 114 is enabled in the first connector 100, thereby making it possible to protect the interlock circuit. Even further, a problem that a high voltage is blocked due to an unstable contact between the connectors is prevented, thereby additionally improving marketability and stability.

(30) Hereinabove, although the present disclosure has been described with reference to embodiments and the accompanying drawings, the present disclosure is not limited thereto, but may be variously modified and altered by those skilled in the art to which the present disclosure pertains without departing from the spirit and scope of the present disclosure claimed in the following claims.
