Description

TECHNICAL FIELD [0001] The present invention relates to a high voltage connector and a fastening method thereof,

The present invention relates to a high-voltage connector, and more particularly, to a high-voltage connector and a fastening method thereof, which can electrically connect both ends of a wire by fastening a mail and a female connector within a limited space such as an engine room of an automobile.

In recent years, the proportion of wiring harnesses connecting these parts with each other has increased due to the increase of electrical components. However, these electric parts must be supplied with a predetermined voltage from a low voltage to a high voltage according to the purpose and function.

Therefore, the connector connected to each electric component is also divided into a low voltage connector and a high voltage connector and is used in parallel. In particular, a high voltage cable through which a high current flows is connected to a high voltage connector.

The operator rotates the lever portion 30 while slidably inserting the mail connector 10 into the female connector 20. When the mail connector 10 is completely engaged with the female connector 20, the lever portion 30 rotates and is disposed perpendicular to the engaging direction. As a result, the mail connector 10 and the female connector 20 are locked by the lever portion 30 and are not released.

However, the fastening method according to the conventional engaging direction requires a larger space in the height direction after fastening due to the presence of the lever portion 30. [ As a result, the high-voltage connector including the lever portion 30 which is subject to such a space restriction has a problem of being unsuitable for designing for a vehicle package. This is because, in the design of the vehicle package, the space in the width and width direction is relatively sufficient, and the reduction in the height direction is most important.

Further, the fastening structure using the lever portion 30 has a problem in that workability is deteriorated depending on the positions of the mail and the female connectors 10 and 20 when fastening or separating the fastening structure. In addition, there is a problem that the lever unit 30 is broken due to incomplete fastening or forcible fastening depending on the operator.

Further, since many parts are installed in a limited space in addition to the high voltage connector in the automobile, there is a problem that the high voltage connector is damaged due to interference or collision due to other peripheral parts due to vibrations or shocks generated during operation of the vehicle.

When torque is applied to the bolts 302 of the bolt assembly 300 which are inserted into the fastening holes 150 of the female connector 100, the female connector 100 is tightly fastened to the male connector 200 .

Fig. 5 is a perspective view of the female connector 100 of Fig. 2, Fig. 6 is a perspective view showing each manufacturing step of Fig. 5, Fig. 7 is an enlarged A- Fig.

Referring to FIGS. 5 to 8, the female connector 102 is disposed in the inner space of the female connector 100. Specifically, the female connector 100 includes an outer housing 110, and first and second inner housings 120 and 130. In this case, the outer housing 110 is formed of a metal such as aluminum for shielding electromagnetic waves and noise, and the first and second inner housings 120 and 130 are formed of a plastic material.

The outer housing 110 is formed to have a bottom surface and a side surface. The opening side is a passage through which the female terminal 102 to which the cable is connected is inserted. Further, the fastening hole 150 is formed on the upper surface of the outer housing 110.

The outer housing 110 may further include at least two protrusions 112 protruding from the inner surface of the upper surface thereof in the vertical direction and exposed through the opening of the lower surface of the outer housing 110. The projections 112 according to an embodiment of the present invention are arranged in a pair.

The outer housing 110 is formed with first and second ribs 114 and 116 protruding along the circumference of the rim. Here, the first ribs 114 are located on the inner side of the outer housing 110 as compared with the second ribs 116. As a result, a space having a constant width may be formed between the first and second ribs 114 and 116.

Further, an inner seal 118 may be disposed on the outer surface of the first rib 114. At this time, the inner seal 118 is preferably formed of an elastic material such as rubber or silicone.

Next, the first inner housing 120 is accommodated and coupled to the inside of the outer housing 110. The first inner housing 120 may have a guide pattern portion 122 for guiding the female terminal 102 inserted therein. At this time, the female terminal 102 is fixed to each end of the guide pattern portion 122.

To this end, the guide protrusion 122 may be provided with a first protrusion 124 for fastening the female terminal 102 thereto. At this time, the first step 124 protrudes from the first inner housing 120 in the vertical outward direction, thereby preventing the female terminal 102 from moving in the reverse direction of insertion.

The first inner housing 120 is formed with through-holes through which the protrusions 112 can pass, respectively.

The second inner housing 130 functions to seal the lower opening of the outer housing 110 while covering the first inner housing 120. The second inner housing 130 may have a second jaw 134 for locking and fixing the female terminal 102 to the same or similar shape as the first jaw 124.

That is, the second jaw 134 protrudes in the vertical outer direction from the second inner housing 130 to prevent the female terminal 102 from being detached. Accordingly, when the second inner housing 130 is received and coupled to the outer housing 110, the first jaw 124 and the second jaw 134 are opposed to each other.

As a result, when the second inner housing 130 covers and hermetically closes the first inner housing 120, the male terminal 102 can be simultaneously hooked on the first and second jaws 124 and 134 .

The mail terminal 202 protrudes upward from the upper surface of the mail connector 200 and comes into contact with the mail terminal 102. As a result, a current can flow between the mail and the mail connector 100 (200). At this time, at least one or more mail terminals 202 are formed corresponding to the number of the mail terminals 102.

The male terminal is connected to the female terminal so as to be in contact with the crimping direction of the cable to be crimped and connected to the female terminal. That is, the direction in which the female terminal and cable are pressed and the direction in which the female terminal and the male terminal are joined form an angle of 90 degrees. This is possible because the female connector 100 is disposed on the upper surface of the mail connector 200 vertically downward from the upper side of the mail connector 200. The mail terminal 202 becomes perpendicular to the cable connected to the mail terminal 102 when the mail terminal 102 comes into contact with the mail terminal 202 in the embodiment of the present invention.

When the male connector 100 and the male connector 200 are tightly fastened using the bolt assembly 300 disposed in the fastening hole 150, the use of space can be reduced by about 50% .

At this time, the fastening protrusion 208 protrudes in the upward direction in parallel with the mail terminal 202, and a thread is formed at the lower side of the inner circumferential surface corresponding to the fastening hole 150. Here, the thread formed on the fastening protrusion 208 corresponds to a female thread, and the thread of the bolt 302 of the bolt assembly 300 corresponds to a male thread.

However, it is preferable that the thread of the fastening protrusion 208 is not formed on the upper side of the inner peripheral surface. This is because the female connector 100 is merely disposed on the upper surface of the mail connector 200 and the end of the threaded bolt 302 is fastened to the fastening protrusion 208 (The mounting structure 1)

The receiving groove 212 is formed on the upper surface of the mail connector 200 and functions to receive the projection 112 described above. For this reason, the receiving groove 212 is formed in the mail connector 200 corresponding to the position of the protrusion 112 formed in the female connector 100. (Mounting structure 2)

In addition, third and fourth ribs 204 and 206 protruding along the circumference may be formed on the upper surface of the mail connector 200. The third and fourth ribs 204 and 206 can be more easily inserted and fixed between the female connector 100 and the male connector 200 in correspondence with the first and second ribs 114 and 116 .

Therefore, the bolt 302 may be further inserted with the O-ring 304 and the dering 306 to shield a part of the space and waterproof it. At this time, the O-ring 304 and the dringing 306 may be formed of rubber, silicone, or the like.

To this end, first and second grooves are formed on the outer circumferential surface of the bolt 302. Here, the second groove is a groove disposed in a downward direction of the first groove.

Then, the O-ring 304 is fitted into the first groove, and the dering 306 is sandwiched between the head of the bolt 302 and the O-ring 304. Specifically, when the bolt 302 is inserted into the fastening hole 150, the O-ring 304 is pressed by the first groove and the inner circumferential surface of the fastening hole 150 to block a space in which water can penetrate.

On the other hand, since the dering ring 306 is fitted only on the outer circumferential surface of the bolt 302, the dering ring 306 has a dering groove 152 in which the dering ring 306 can be seated in the fastening hole 150 due to the thickness of the ring itself Lt; / RTI > The dingling 306 can block the gap between the dingling groove 152 and the inner circumferential surface of the fastening hole 150 to exhibit a waterproof function.
