5 to 8, in the female connector 100, a female terminal 102 is disposed in an internal space. Specifically, the female connector 100 includes an outer housing 110 and first and second inner housings 120 and 130 . At this time, the outer housing 110 is formed of a metal material such as aluminum to shield electromagnetic waves or noise, while the first and second inner housings 120 and 130 are usually formed of a plastic material.

The outer housing 110 is formed such that the lower surface and one side of the outer housing 110 are open. And, the opened side becomes a passage into which the female terminal 102 to which the cable is connected is inserted. In addition, the fastening hole 150 is particularly formed on the upper surface of the outer housing 110 .

In addition, at least two or more protrusions 112 protruding in a vertical direction from an inner surface of the upper surface of the outer housing 110 and exposed through an opening on the lower surface of the outer housing 110 may be further formed. Protrusions 112 according to an embodiment of the present invention are arranged in pairs.

Further, the outer housing 110 has first and second ribs 114 and 116 protruding along the circumference of the rim of the lower surface. Here, the first rib 114 is located more inside of the outer housing 110 than the second rib 116 . As a result, a space having a predetermined width may be formed between the first and second ribs 114 and 116 .

In addition, an inner seal 118 may be further disposed on an 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 silicon.

Next, the first inner housing 120 is accommodated and coupled into the outer housing 110 . Also, a guide pattern portion 122 guiding the inserted female terminal 102 may be formed in the first inner housing 120 . At this time, the female terminal 102 is fixed to each end of the guide pattern part 122 .

To this end, a first protrusion 124 for engaging and fixing the female terminal 102 may be formed in the guide pattern portion 122 . At this time, the first protrusion 124 protrudes vertically outward from the first inner housing 120 to prevent the female terminal 102 from being moved in the direction opposite to insertion and being separated.

In addition, the first inner housing 120 is formed with through-holes through which each of the above-described protrusions 112 can pass.

Also, the second inner housing 130 covers the first inner housing 120 and serves to close the opening of the lower surface of the outer housing 110 . In addition, a second protrusion 134 for engaging and fixing the female terminal 102 may be formed in the second inner housing 130 in the same or similar shape as the first protrusion 124 .

That is, the second protrusion 134 protrudes vertically outward from the second inner housing 130 to prevent the female terminal 102 from being separated. Accordingly, when the second inner housing 130 is accommodated and coupled to the outer housing 110, the first protrusion 124 and the second protrusion 134 face each other.

As a result, when the second inner housing 130 is hermetically coupled while covering the first inner housing 120, the female terminal 102 can be simultaneously caught and fixed by the first and second protrusions 124 and 134. .

Meanwhile, like the first inner housing 120 , through holes through which the above-described protrusions 112 pass may be formed in the second inner housing 130 . As a result, the female connector 100 may have a structure in which the protrusions 112 protrude and are exposed through the through holes.
In addition, as shown in FIGS. 4 and 8 , the second inner housing 130 is formed such that the end of the second inner housing supports the lower surface of the inner seal 118 . As a result, even if the sealing force of the inner seal 118 is increased, it is possible to prevent the inner seal 118 from being separated during attachment and detachment from the male connector.

Referring to FIGS. 9 and 10 , the male connector 200 includes a male terminal 202 , a fastening protrusion 208 and a receiving groove 212 . The male terminal 202 protrudes upward from the upper surface of the male connector 200 and contacts the female terminal 102 . As a result, current can flow between the male and female connectors 100 and 200 . At this time, at least one male terminal 202 is disposed in correspondence with the number of female terminals 102 .

And, the male terminal is coupled to the female terminal so as to contact perpendicularly to the crimping direction of the cable connected to the female terminal by crimping. That is, the crimping direction of the female terminal and the cable and the coupling direction of the female terminal and the male terminal form an angle of 90 degrees. This is possible because the female connector 100 is disposed on the upper surface of the male connector 200 vertically downward from the upper side of the male connector 200 . In one embodiment of the present invention, when the female terminal 102 contacts the male terminal 202, the male terminal 202 is perpendicular to the cable connected to the female terminal 102.

In addition, when the female connector 100 and the male connector 200 are firmly fastened using the bolt assembly 300 disposed in the fastening hole 150, space usage in the height direction can be reduced by about 50% or more compared to the related art. .

At this time, the fastening protrusion 208 protrudes upward in parallel with the male terminal 202, and a screw thread is formed on 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 the female thread, and the thread of the bolt 302 of the bolt assembly 300 corresponds to the male thread.

However, it is preferable that the thread of the fastening protrusion 208 is not formed on the upper side of the inner circumferential surface. This is because the female connector 100 is merely disposed on the upper surface of the male connector 200, and the end of the threaded bolt 302 is fastened to the fastening protrusion 208 in the temporary installation state before fastening the bolt 302. ) to be accommodated in the inner space of (Temporary structure 1).

In addition, the accommodating groove 212 is formed on the upper surface of the male connector 200 and serves to accommodate the above-described protrusion 112 . For this reason, the accommodating groove 212 is formed on the male connector 200 corresponding to the position of the protrusion 112 formed on the female connector 100. (Temporary mounting structure 2)

In addition, third and fourth ribs 204 and 206 protruding along the circumference may be formed on the upper edge of the male connector 200 . The third and fourth ribs 204 and 206 correspond to the first and second ribs 114 and 116 described above to facilitate temporary coupling between the female connector 100 and the male connector 200. can guide you.

Specifically, according to one embodiment of the present invention, when the female connector 100 and the male connector 200 are temporarily coupled, the third rib 204 is between the first and second ribs 114 and 116. and the second rib 116 is accommodated between the third and fourth ribs 204 and 206. At this time, the third rib 204 is in close contact with the inner seal 118. (Temporary structure 3)

The provisional mounting structures 1 to 3 described above increase work convenience when the female connector 100 is arranged and coupled to the upper surface of the male connector 200 . This is because each structure can serve as a guide so that the work can be easily performed in the course of the operator's tentative coupling.

Also, when the female connector 100 and the male connector 200 are fastened together using the bolts 302, the temporary mounting structures 1 to 3 can improve work convenience. This is because each structure can prevent the female connector 100 or the male connector 200 from rotating clockwise when tightening the bolt 302 by applying torque to the bolt 302 .

In addition, each structure can prevent the female connector 100 or the male connector 200 from being displaced from each other when excessive torque is applied to the bolt 302, that is, when the female connector 100 or the male connector 200 is further rotated clockwise or counterclockwise due to the overtorque. because there is

In addition, torque is applied to the bolt 302 inserted into the female connector 100 so as to vertically fasten with the male connector 200. can

Therefore, the O-ring 304 and the D-ring 306 are further inserted into the bolt 302 to block some of the space and to make it waterproof. At this time, the O-ring 304 and the D-ring 306 may be formed of rubber or silicon material.

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 below the first groove.

Then, the O-ring 304 is inserted into the first groove, and the D-ring 306 is inserted 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 receives pressure while being pressed by the first groove and the inner circumferential surface of the fastening hole 150 to block a space through which water can penetrate.

On the other hand, since the D-ring 306 is only inserted into the outer circumferential surface of the bolt 302, the D-ring 306 has a D-ring groove 152 in the fastening hole 150 due to the thickness of the ring itself, in which the D-ring 306 can be seated. more formed In addition, the D-ring 306 can block the gap between the D-ring groove 152 and the inner circumferential surface of the fastening hole 150 to exhibit a waterproof function.
