According to the drawings, the outer housing 10 forms the appearance of the safety connector of the present invention. The out-housing 10 is made of an insulating synthetic resin. In this embodiment, the outer housing 10 is formed in a substantially hexahedral shape. A first inner space 12 is formed in the outer housing 10. The first inner space 12 is opened to one side of the out-housing 10. An outer guide surface 10 'is formed along the entrance edge at which the first inner space 12 is opened. The outer guide surface 10 'serves to guide the tip of the relative safety connector when engaged with the relative safety connector.

On both side plates of the out-housing 10, interference avoidance slots 11 are formed by a predetermined length. The interference avoiding slot 11 prevents the interlocking protrusion of the relative safety connector from interfering with the side plate of the out- The interference avoiding slot 11 is formed to be open to the front end of the outer housing 10. That is, the entrance of the interference avoiding slot 11 is at the front end of the out-housing 10.

A mounting fence 14 is formed in the first inner space 12. The mounting fences 14 are formed at a predetermined distance from the inner surface of the first inner space 12. [ The mounting fence 14 protrudes from the inside of the first inner space 12 toward the inlet, though not protruding to the front end of the inlet of the out-housing 10. The inner guide surface 14 'is formed obliquely along the inside of the tip end of the mounting fence 14. And the mounting fence 14 becomes thinner toward the front end by the inner guide surface 14 '. The inner guide surface 14 'also serves to guide the insertion of the corresponding tip of the relative safety connector as the outer guide surface 10'.

A hook piece (16) is formed at the tip of the mounting fence (14). The hooking piece 16 is provided at the tip of the mounting fence 14 facing each other. In this embodiment, the hooking pieces 16 are two pairs. The number of the hooking pieces 16 varies depending on design conditions. The hooking piece 16 can be slightly elastically deformed. A hooking hole (18) is formed in the hooking piece (16). Although the hooking hole 18 is formed through the hooking piece 16 in the present embodiment, the hooking hole 18 may not necessarily be formed in a groove shape recessed into the hooking piece 16. The protruding degree of the mounting fence 14 is relatively small at the portion where the hook piece 16 is present. The tip end of the hook piece 16 is at the same position as the tip end of the mounting fence 14 at another portion.

On both outer surfaces of the outer housing 10, there is a rotation center shaft 19. The rotation center shaft 19 is a rotation center of the rotation lever 20, which will be described below. Reference numeral 19 'denotes a seal coupling hole for inserting a coupling protrusion of a seal (not shown) provided inside the outer housing 10 so that the seal is coupled to the outer housing 10. The front end of the relative safety connector is closely attached to the seal to perform a waterproof function.

The outer housing (10) is provided with a rotation lever (20) rotatably about the rotation center shaft (19). The rotation lever 20 is used when the coupling force and separation force with the relative safety connector is large. That is, if the coupling force and the separating force with the relative safety connector are not large, the rotation lever 20 may not be used.

The rotating lever 20 has mounting plates 22 at both ends thereof and a connecting portion 24 for connecting the mounting plates 22 therebetween. The connection portion 24 also serves as a handle. The mounting plate 22 is mounted on both outer surfaces of the outer housing 10. That is, the rotation center shaft 19 passes through the mounting plate 22.

The mounting plate (22) is provided with a guide slot (26). The guide slot 26 is a portion where the cooperating protrusion in the relative safety connector is guided. At the entrance of the guide slot 26, there is a connecting bar 28 connecting both ends in the width direction of the guide slot 26 to each other. The connecting bar 28 prevents the strength of the mounting plate 22 from being weakened by the guide slot 26 without interfering with the interlocking protrusion from entering the guide slot 26.

An inner housing 30 is installed inside the mounting fence 14 of the outer housing 10. The inner housing 30 is also made of an insulating synthetic resin. The inner housing 30 has a substantially hexahedron shape as shown in FIG. The inner housing 30 is located inside the mounting fence 14 of the first inner space 12 of the out housing 10.

A second inner space (32) is formed in the inner housing (30). A bottom plate 33 is formed at the bottom of the second inner space 32 and a side wall 34 extending at the edge of the bottom plate 33 is formed. On the outer surface of the side wall 34, a hooking protrusion 36 protrudes. The hooking jaw 36 is hooked on the hooking piece 16 of the mounting fence 14. [ The hooking jaw 36 is seated on the hooking hole 18 of the hooking piece 16 so that the inner housing 30 is fixed to the mounting fence 14. [ The hooking jaws 36 are formed in a number corresponding to the positions corresponding to the hooking pieces 16.

The hooking jaw (36) has a hooking groove (37). In the hooking groove 37, the end of the hooking beam 52 of the shield shell 40 to be described below is seated.

The second inner space (32) of the inner housing (30) is provided with an interlock part (38). The interlock portion 38 serves to prevent sparks from being generated when the contact between the safety connector and the terminal provided in the mating safety connector and separation thereof occurs. That is, the terminals are electrically coupled later than the terminals are coupled to each other. When the terminals are separated, the power is disconnected before the terminals are electrically disconnected before the terminals are disconnected. Since the specific configuration of the interlock unit 38 is not a gist of the present invention, its explanation is omitted.

The structure of the inner housing 30 in the second inner space 32 will not be described for the sake of convenience in this embodiment. A terminal (not shown) or the like is installed in the second inner space 32. The terminal is coupled to the terminal of the relative safety connector and serves to connect the circuit.

A shield shell 40 is provided on the outer surface of the inner housing 30. The shield shell 40 is made of a metal material. The shield shell 40 is positioned between the outer surface of the inner housing 30 and the inner surface of the mounting fence 14 when the inner housing 30 is mounted to the mounting fence 14 of the out- And shields electromagnetic waves generated at a terminal installed in the second inner space 32 of the inner housing 30. Of course, the shield shell 40 is also electrically connected to a corresponding portion of the relative safety connector to serve as a ground.

The shield shell 40 surrounds the outer surface of the inner housing 30 with two of the shield shell 40 having the same configuration. The shield shell 40 shields half of the bottom plate 32 of the inner housing 30 and the shell side wall 44 formed orthogonally along the edge of the shell bottom plate 42, (30) of the inner housing (30).

A contact piece 46 is formed on the shell side wall 44 having a relatively large area among the shell side walls 44 of the shield shell 40. The contact piece 46 has a cantilever shape. At the free end of the contact piece 46 is a contact tip 48 which is in electrical contact with the configuration for grounding the mating safety connector. The contact pieces 46 project further from the outer surface of the shell side wall 44 toward the free end. At the free end of the contact piece 46, a contact tip 48 is made parallel to the shell side wall 44. The contact tip 48 is in electrical contact with the configuration for grounding the mating safety connector. In the present embodiment, three contact pieces 46 are arranged side by side. The number of the contact pieces 46 varies depending on design conditions.

A hooking hole 50 is formed through the shell side wall 44 provided with the contact piece 46 and the hooking bar 52 extends through the hooking hole 50 by a predetermined length. The tip end of the hook beam 52 is seated in the hook groove 37 formed in the hook 36 of the inner housing 30. The shield shell 40 is dimensioned so as to be closely attached to the outer surface of the inner housing 30.

Hereinafter, the construction and use of the safety connector according to the present invention will be described in detail.

The outer housing 10, the rotary lever 20, and the inner housing 30 are made separately. In FIG. 2, the rotary lever 20 is shown mounted on the outer housing 10. Of course, the shield shell 40 is also made separately and provided to the assembly line. Two shield shells (40) are provided on the outer surface of the inner housing (10). The tip end of the hooking bracket 52 of the shield shell 40 is seated and hooked on the hooking groove 37 formed in the hooking jaw 36 of the inner housing 30 and the shell bottom plate of the shielding shell 40 42 and the shell side wall 44 are in close contact with the bottom plate 32 and the side wall 34 of the inner housing 30.

The state in which the two shield shells 40 are installed on the inner housing 30 is shown in FIG. The assembly shown in FIG. 5 is seated inside the mounting fence 14 of the out-housing 10. At this time, the hooking jaws 36 of the inner housing 30 are seated on the hooking holes 18 of the hooking pieces 16 formed on the mounting fences 14. The inner housing 30 is fixed to the mounting fence 14 by receiving the hooking jaws 36 of the inner housing 30 on the hooking pieces 16.

When the inner housing 30 is mounted on the mounting fence 14 formed in the first inner space 12 of the outer housing 10, the inner housing 30 is inserted between the outer surface of the inner housing 30 and the inner surface of the mounting fence 14 The shield shell 40 is positioned and the shield shell 40 surrounds the inner housing 30. [

Next, a part constituting the terminal and the interlock part 38 is provided in the second inner space 32 of the inner housing 30. The rotation lever 20 may be mounted on the rotation center shaft 19 of the outer housing 10.

In this way, a safety connector as shown in Fig. 1 is completed. The safety connector is coupled to a relative safety connector to supply electric power to various parts from a power source such as a battery in an electric vehicle or a hybrid vehicle.

The safety connector is coupled with the relative safety connector so that the entrance of the guide slot 26 of the rotary lever 20 coincides with the entrance of the interference avoidance slot 11 formed in the outer housing 10 The position of the rotary lever 20 is first set. In this state, the safety connector of the present invention approaches the relative safety connector so that the cooperating protrusion of the relative safety connector enters the entrance of the interference avoiding slot 11 and the guide slot 26.

Next, the rotation lever 20 is rotated to move the cooperating protrusion of the relative safety connector along the guide slot 26 so that the relative safety connector and the safety connector of the present invention approach each other so that the terminals are coupled to each other .

By this operation, the tip of the relative safety connector enters the space between the inner surface of the outer housing 10 and the mounting fence 14 and is brought into close contact with the seal. In this case, the waterproof function can be performed by the seal.

Further, the rotation of the rotation lever 20 electrically connects the interlock portion 38 after the terminals are coupled in the process of coupling the relative safety connector and the terminal of the safety connector of the present invention. That is, the interlock portion 38 and the interlock portion (not shown) of the relative safety connector are electrically connected. The electric connection of the interlock part (38) makes power connection through the terminal.

The contact piece 46 of the shield shell 40 is electrically connected to the grounding structure of the relative safety connector. The contact piece 46 has a cantilevered shape and the contact tip end 48 protrudes from the shell side wall 44. When the relative safety connector enters the inside of the out housing 10, The contact tip 48 is brought into contact with the structure. Such contact provides an electrical connection for grounding.

The shield shell 40 surrounds the inner housing 30 during the use of the electric vehicle or the hybrid vehicle and can serve as an electromagnetic shielding shield while at the same time providing electrical connection to the grounding structure on the side of the relative safety connector, It can be done safely.

Next, when there is a need to maintain the electric vehicle or the hybrid vehicle, first, the safety connector of the present invention is disconnected from the relative safety connector to cut off the power. To this end, the rotating lever 20 is rotated in a direction opposite to that described above.

At this time, the interlock portions of the interlock portion 38 and the relative safety connector are separated from each other first. The interlocking portion 38 and the interlocking portion of the mating safety connector are disconnected, thereby cutting off the power connection through the terminals. As a result, the terminals are disconnected after the power connection is cut off, thereby preventing the spark from occurring.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention.
