As a result, the manufacturing productivity of the high voltage connector 100 can be improved, and the occurrence of internal corrosion by the metal shielding means can be prevented.

In addition, since the outer housing 120 is formed of a conductive resin, the weight is reduced as compared with an outer housing formed of a conventional metal material. Therefore, the product weight of the high voltage connector 100 of the present invention can be minimized.

Meanwhile, the mating connector 200 to be fastened to the high voltage connector 100 of the present invention may include a mating connector outer housing and a mating connector inner housing. At this time, the mating connector outer housing is formed of a conductive resin, so that electromagnetic waves generated in the connector when the high voltage connector 100 and the mating connector 200 are fastened can be shielded without leakage to the outside.

When the external housing 120 is coupled to the high voltage connector 100 and the mating connector 200, the high voltage connector 100 and the mating connector 200 are electrically connected to each other.

The outer housing 120 includes a coupling part 122 provided with a plurality of coupling means 160 electrically connected to the mating connector 200 when the mating connector 200 is coupled with the mating connector 200. [

The coupling part 122 is inserted into a connector coupling space (not shown) formed in the mating connector 200 and is connected to the mating connector (not shown) by a coupling device such as a bolt to the vehicle so that the outer housing 120 is fastened to the vehicle. 200).

Since the fastening portion 122 and the grounding portion (not shown) of the mating connector 200 contacting the fastening portion 122 are planar, when the high voltage connector 100 and the mating connector 200 are fastened, In some cases, the lifting phenomenon occurs and the electrical contact reliability is deteriorated.

In order to prevent this, when the high voltage connector 100 and the mating connector 200 are coupled with each other, the connecting means 160 protruding from the surface of the fastening portion 122 toward the mating connector 220, So that the electrical contact can be made without lifting the mating connector 200.

More specifically, as shown in FIGS. 4 and 5, the connecting means 160 protrudes toward the mating connector 200 and is formed of a conductive material such as metal.

In particular, the connecting means 160 may be formed by insert injection into the fastening portion 122. Since the connecting unit 160 is integrally formed with the coupling unit 122, it is possible to minimize the time required to form the coupling unit 160 in the coupling unit 122, thereby improving the working efficiency.

Referring again to FIG. 4, the connecting means 160 is formed to protrude from the surface of the fastening portion 122. That is, the connecting means 160 is curved on the upper side so that the upper side of the connecting means 160 is connected to the inner wall of the mating connector 200 when the connecting portion 122 is engaged with the mating connector 200 and is engaged Can be pressurized. As a result, the grounding portion (not shown) of the mating connector 200 and the connecting means 160 are brought into close contact with each other, thereby improving contact efficiency and improving electrical contact reliability.

FIG. 6 is a perspective view showing a second embodiment of the outer housing of FIG. 3, and FIG. 7 is a sectional view taken along the section line VII-VII of FIG.

Prior to the description of FIGS. 6 and 7, the same reference numerals as those shown in FIGS. 2 to 5 among the reference numerals shown in FIG. 6 and FIG. 7 are assumed to have the same configurations and will not be described in detail.

6 and 7, the connecting means 160 is inserted into the outer housing 120, and the outer housing 120 is inserted into the outer housing 120, And the connecting means 160 may be detachably formed in the insertion groove 124. The insertion groove 124 is formed in the insertion groove 124,

That is, when the outer housing 120 is formed, the insertion groove 124 is formed on the surface of the coupling portion 122. When the molding of the outer housing 120 is completed, the coupling means 160 is inserted into the insertion groove 124 do. As the connecting means 160 is mounted as a post-operation after the molding of the outer housing 120, if the connecting means 160 is broken and needs to be replaced, it is separated from the connecting portion 122 and the other connecting means is connected to the connecting portion 122 As shown in Fig.

It is necessary to prevent the connecting means 160 from being separated from the insertion groove 124 of the fastening portion 122 when the connecting means 160 is installed to the fastening portion 122 through the post work as described above.

The connecting means 160 may be elastically deformed when the insertion groove 124 is inserted into the insertion groove 124 and engage with the mating connector 200 when the mating connector 200 is engaged with the mating connector 200. [ And a fixing part 162 which is formed to extend outwardly from the elastic part 162 at both ends of the elastic part 162 and is inserted into the insertion groove 124 to fix the elastic part 162 164).

The elastic portion 162 may be formed in a manner similar to the embodiment in which the curved connecting means 160 protrudes from the surface of the fastening portion 122 when the connecting means 160 described above is inserted into the fastening portion 122 When the connecting means 160 is inserted into the insertion groove 124 of the coupling part 122, the elastic part 162 can correspond to the structure protruding from the insertion groove 124.

4 and 5, when the coupling unit 160 is pressed by the inner wall of the mating connector 200 when the coupling unit 122 of the embodiment of FIGS. 4 and 5 is engaged with and engaged with the mating connector 200, The elastic portion 162 is elastically deformed while being pressed by the coupling portion 122 when the coupling portion 122 is engaged with the mating connector 200 so that the mating connector 200 and the coupling means 160 are completely in close contact with each other, And electrical contact reliability can be improved.

The fixing portion 164 prevents the connecting means 160 inserted into the insertion groove 124 from being separated from the insertion groove 124. As described above, the elastic portion 162 is formed in the shape of a curved surface. At this time, the fixing portion 164 is formed at both ends of the elastic portion 162 in a planar shape in a direction parallel to the direction in which the coupling portion 122 is mounted to the mating connector 200, Similar structures and similar effects can be derived.

The fixing portion 164 may be formed in a direction parallel to the direction in which the high voltage connector 100 is coupled to the mating connector 200 at both ends of the elastic portion 162 (see the arrows in Fig. 2). That is, the connecting means 160 may be installed around the fastening portion 122. Since the connecting means 160 is installed along the forward and backward directions of the coupling portion 122, the insertion groove 124 formed in a direction parallel to the installation direction of the coupling means 160 is formed, It is possible to prevent the connecting means 160 from moving in the forward and backward directions of the outer housing 120. [

FIG. 8 is a perspective view showing a third embodiment of the outer housing of FIG. 3, and FIG. 9 is a sectional view taken along the section line IX-IX of FIG.

Prior to the description of Figs. 8 and 9, the same reference numerals as those shown in Figs. 2 to 7 among the reference numerals shown in Figs. 8 and 9 are assumed to be the same, and a detailed description thereof will be omitted.

8 and 9, the connecting unit 160 is a protrusion 166 formed integrally with the coupling unit 122 and protruding toward the mating connector 200. As shown in FIG.

The protruding portion 166 is formed integrally with the coupling portion 122 on the surface of the coupling portion 122 of the outer housing 120 when the outer housing 120 is formed. Accordingly, the protrusion 166 may be formed of a conductive resin having the same material as that of the outer housing 120. Therefore, even when the high voltage connector 100 and the mating connector 200 are coupled, it is difficult to perform the shielding function.

A plating layer 168 is formed on the surface of the protrusion 166 to allow the plating layer 168 to contact the inner surface of the mating connector 200 when the high voltage connector 100 and the mating connector 200 are coupled, When the connector 100 and the mating connector 200 are coupled to each other.

Also, as described above, the protrusion 166 may be formed of a plastic material, such as the outer housing 120, and may have a spherical shape, so that the protrusion 166 may have predetermined elasticity. When the high voltage connector 100 and the mating connector 200 are coupled to each other, the projecting portion 166 is pressed by the mating connector 200 so that a part of the surface of the projecting portion 166 is distorted, So that they can be engaged with each other.

The connecting means 160 may be formed on the surface of the coupling portion 122 of the outer housing 120. Preferably, at least one of the upper and lower surfaces of the coupling portion 122 is formed, May be formed at a plurality of positions in contact with the substrate 200.

The protruding height of the connecting means 160 with respect to the surface of the fastening portion 122 may be variously formed according to the reliability of electrical contact with the mating connector 200. [

The outer housing 120 of the high voltage connector 100 is formed of a conductive resin so that the outer housing 120 is shielded by the high voltage connector 100 when the high voltage connector 100 and the mating connector 200 are coupled, The electromagnetic wave can be shielded from the high-voltage connector by preventing the electromagnetic wave from leaking to the outside.

Since the outer housing 120 of the high voltage connector 100 itself serves as the shielding means when the high voltage connector 100 and the mating connector 200 are coupled to each other, no separate metal shielding means is required, The number of parts can be reduced. As a result, the manufacturing productivity of the high voltage connector 100 can be improved, and the occurrence of internal corrosion by the metal shielding means can be prevented.

In particular, when the high-voltage connector 100 and the mating connector 200 are coupled to each other, the noise generated in the connector can be grounded by providing connection means made of metal on the outer housing 120 of the high-voltage connector 100. Thus, the shielding performance of the high voltage connector can be kept constant.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
