Description

connector {CONNECTOR}

The present invention relates to a connector, and more particularly, to a connector in which the insertion force of a terminal is reduced.

In general, there are many electronic devices in a vehicle, and these are electrically connected to other electronic devices or power sources through cables. In this case, when the cable is directly connected to an electronic device or other power source and device, the operation is complicated and takes a lot of time, so it is usually connected using a connector. Such a connector is typically composed of a terminal connected to the end of the cable, and a housing made of an insulating material to protect the terminal and prevent short circuit. The connector has a terminal installed inside the housing, and a wire is connected to the terminal so as to extend to the outside of the housing. Such a connector is coupled to a counterpart connector to perform electrical connection by electrically connecting each terminal.

Connectors are used in voltages of various strengths. Recently, since a high voltage is used to drive a motor in an electric vehicle or a hybrid vehicle, a high voltage connector is often used.

The wire used in the high voltage connector has a shield wire for grounding between the inner insulation layer surrounding the core wire and the outer insulation layer forming the exterior of the wire. When the terminal and the wire are connected, the shield wire should not be in electrical contact with the wire and should be electrically connected to the shield shell inside the connector.

To this end, the front end of the shield wire is compressed between the support ring and the crimp ring at the front end of the wire located adjacent to the terminal.

However, in the high voltage connector according to the prior art, the friction force between the shield shell and the crimp ring configured for grounding and the friction force between the shield shell and the terminal act simultaneously to increase the insertion force. In the process of inserting the terminal to which the wire is connected, a problem occurred that the terminal and the wire were damaged.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector in which the insertion force of a terminal connected to a wire which is inserted into a housing and connected to a shield shell and grounded wire is reduced.

According to a feature of the present invention for achieving the above object, the present invention has a terminal assembled at the tip, a wire in which a shield wire inside is folded outward and compressed by a crimping ring, and an insertion hole into which the terminal is inserted. A housing formed to pass through, a shield shell installed in close contact with the inner surface of the insertion hole and extending with an elastically deformable ground leg at a tip end thereof, coupled to the rear surface of the housing, and pressing the ground leg to make contact with the crimping ring It includes a rear holder.

A locking end is formed on the inner surface of the insertion hole of the housing in a direction in which the diameter of the insertion hole decreases.

An inner surface of the insertion hole of the housing has a predetermined width in the extending direction of the insertion hole, and a rotation preventing rib protrudes toward the center of the insertion hole.

A plurality of the anti-rotation ribs are arranged at an equal angle.

A cantilever-shaped lance having elasticity on the inner surface of the insertion hole of the housing protrudes toward the center of the insertion hole to fix the terminal.

The shield shell includes a shell body installed on the inner surface of the insertion hole, and a grounding leg extending from one end of the shell body and elastically deformed toward the center of the insertion hole.

The ground leg includes a first deformed portion extending from one end of the shell body toward the center of the insertion hole, and a contact portion is formed at a point where the first deformed portion meets the first deformed portion by bending in the opposite direction to the extending direction of the first deforming portion a second deformable portion and a pressing portion extending from the second deforming portion and having a pressing surface formed in a direction perpendicular to the insertion direction of the shield shell, wherein when the pressing portion is pressed by the rear holder, the contact portion is the Grounded in contact with the crimp ring.

The anti-rotation rib is fitted to the shell body to form an anti-rotation slit to prevent rotation of the shield shell.

A portion of the shell body is cut in the shell body, and the hooking piece is bent outwardly in a cantilever shape having elasticity.

Both ends are fixed to the shell body, and a contact piece is formed that protrudes convexly to the outside of the shell body and is in close contact with the inner surface of the insertion hole.

The rear holder includes a base having a wire hole through which the wire passes, a side wall protruding along an edge of the base and coupled to the outer surface of the housing, and a pressing protrusion protruding parallel to the side wall from the base, When the rear holder is coupled to the rear surface of the housing, when the pressing protrusion presses the pressing portion, the first deformable portion and the second deformable portion are deformed so that the contact portion and the crimp ring come into contact with each other.

A waterproof seal for shielding the insertion hole is provided between the crimp ring and the rear holder.

A through hole is formed in the waterproof seal at a position corresponding to the pressing protrusion.

A contact protrusion in close contact with the outer surface of the pressing protrusion protrudes from the inside of the through hole of the waterproof seal.

In the connector according to the present invention, the following effects can be obtained.

According to the present invention, when the rear holder is coupled to the housing, the grounding leg formed on the shield shell in the housing is deformed by the pressing protrusion of the rear holder, and is contacted with the crimp ring to be grounded. In the process of inserting the terminal by this structure, the contact between the terminal and the shield shell is lost and frictional force is not generated, so that the insertion force of the terminal is reduced.

According to the present invention, an anti-rotation rib is formed in the housing, and an anti-rotation slit is formed in the shield shell installed in the housing, so that the anti-rotation rib and the anti-rotation slit are coupled, thereby preventing the shield shell from arbitrarily rotating inside the housing. Accordingly, the shield shell itself rotates and frictional heat generated by continuous contact with the terminal is reduced, thereby increasing the stability of the connector.

According to the present invention, a through hole is formed in the waterproof seal, and a contact protrusion is formed on the inner surface of the through hole to be in close contact with the outer surface of the pressing protrusion of the rear holder. The structure in which the pressure protrusion is formed on the rear holder reduces the insertion force between the housing and the terminal, while also performing a waterproof function.

First, a configuration of a connector constituting a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The terminal 15 to which the wire 10 is connected is inserted in the connector of this embodiment in one direction of the housing 20, and the terminal of the connector may protrude parallel to the direction in which the terminal 15 is inserted.

2 and 3, the wire 10 is formed around a center line 11 made of a conductor, an inner insulating layer 12 surrounding the center line 11, and the outside of the inner insulating layer 12 It is composed of a shield wire 13 and an external insulating layer 14 formed outside the shield wire 13 . Here, the shield wire 13 made of a conductive material blocks electromagnetic waves generated therein to prevent the electromagnetic waves from affecting nearby electronic devices.

The center line 11 is a passage through which current directly flows, the inner insulating layer 12 is positioned between the center line 11 and the shield line 13 to perform an insulating function, and the outer insulating layer 14 is the It functions as an insulation between the shield wire 13 and the outside. Accordingly, the center line 11 is made of a material having good electrical conductivity, and the inner insulating layer 12 and the outer insulating layer 14 are made of a material having good insulating properties. In particular, the shield wire 13 is provided to surround the outer surface of the inner insulating layer 12, and the shield wire 13 is made of a wire made of a conductive material in the form of a mesh, and performs a grounding role.

As can be seen in FIG. 3 , at the end of the wire 10 , a center line 11 , an inner insulating layer 12 , a shield wire 13 , and an outer insulating layer 14 are formed to be exposed in sequence, and a support ring 16 ) is inserted into the wire 10 so as to surround the outer insulating layer 14 . The shield wire 13 of the wire 10 is bent to cover the outer surface of the support ring 16, and the crimp ring 17 is seated thereon, so that the shield wire 13 is connected to the support ring 16 and the crimp ring. It is sandwiched between (17).

Meanwhile, a terminal 15 is coupled to the front end of the center line 11 .

The crimping ring 17 is formed to extend in the longitudinal direction of the wire 10 in a cylindrical shape made of a conductive material. The crimp ring 17 is fitted to the outer surface of the support ring 16 with the shield wire 13 interposed therebetween, and presses the shield wire 13 seated on the outer surface of the support ring 16 .

The wire 10 is provided with a waterproof seal 18 adjacent to the rear surface of the crimping ring 17 . The waterproof seal 18 shields the rear surface of the housing 20 into which the wire 10 is inserted to block the inflow of moisture and foreign substances from the outside.

Referring to the waterproof seal 18 shown in FIG. 7 , a through hole 19 is formed in the waterproof seal 18 . In the through hole 19, a pressing protrusion 45 of the rear holder 40, which will be described later, passes through. On the inner surface of the through hole 19, a close contact protrusion 19' protrudes toward the center of the through hole 19 to completely block a gap that may occur between the waterproof seal 18 and the pressure protrusion 45. Make sure that the waterproof function is not deteriorated.

4, in the connector of the present invention, the housing 20 forms an exterior. An insertion hole 21 is formed in the housing 20 along the longitudinal direction. The insertion hole 21 is formed to pass through the housing 20 , and the terminal 15 is seated inside the insertion hole 21 .

A locking end 22 is formed inside the insertion hole 21 . The engaging end 22 protrudes in a direction in which the diameter of the insertion hole 21 decreases to form a stepped surface. The front end of the shield shell 30 inserted into the insertion hole 21 and installed inside the housing 20 is seated at the engaging end 22 . When the front end of the shield shell 30 is seated on the locking end 22 , the shield shell 30 is prevented from moving in the insertion direction of the shield shell 30 .

An anti-rotation rib 23 having a predetermined width in the longitudinal direction of the housing 20 protrudes toward the center of the insertion hole 21 on the inner surface of the insertion hole 21 . The anti-rotation rib 23 is disposed at an angle. The anti-rotation rib 23 prevents the shield shell 30 installed inside the housing 20 from being arbitrarily rotated. Accordingly, the shield shell 30 is prevented from moving in the insertion direction of the shield shell 30 by the engaging end 22 , and the central axis C is rotated by the rotation preventing rib 23 as a rotation axis. It is fixed in the insertion hole 21 so as to be prevented.

A cantilever-shaped lance 24 having elasticity is formed on the inner surface of the insertion hole 21 . The lance 24 is hung on one side of the terminal 15 so as to prevent the terminal 15 from moving in the longitudinal direction of the housing 20 .

5, the shield shell 30 serves to block noise such as a magnetic field or electromagnetic wave generated by a current flowing through the wire 10, and the shield wire 13 of the wire 10 and contacted and grounded. The shield shell 30 forms an exterior of the shell body 31 . The shield shell 30 is inserted into the insertion hole 21 of the housing 20 , and a part of the shield shell 30 comes into contact with the shield wire 13 of the wire 10 to form a grounding structure. The shell body 31 is formed in a substantially cylindrical shape by rolling a plate-shaped metal.

The anti-rotation slit 32 is formed in the shell body 31 to correspond to the anti-rotation rib 23 . The anti-rotation slit 32 is a slit formed in the shell body 31, into which the anti-rotation rib 23 is fitted. Therefore, like the anti-rotation rib 23, it may be formed at an equal angle. The anti-rotation slit 32 extends along the longitudinal direction of the shell body 31 from one end of the shell body 31 . However, it is formed shorter than the length of the shell body 31 and extends approximately to the midpoint of the shell body 31 . The length of the anti-rotation slit 32 may be variously changed according to the size of the housing 20 and the extension length of the anti-rotation rib 23 . At this time, since the anti-rotation slit 32 must be fitted into the anti-rotation rib 23, one end of the anti-rotation slit 32 must be in an open form.

A locking piece 33 is formed on the shell body 31 . The locking piece 33 is bent toward the outer surface by cutting a part of the shell body 31 . That is, the locking piece 33 protrudes to the outside of the shell body 31 in the shape of a plate-shaped cantilever having elasticity. When the shield shell 30 is inserted into the insertion hole 21 , the locking piece 33 protrudes in a direction opposite to the insertion direction of the shield shell 30 , and is located inside the insertion hole 21 . Because it is hung, the shield shell 30 is prevented from being separated in the opposite direction to the insertion direction.

A contact piece 34 is formed on the shell body 31 . The close contact piece 34 has both ends fixed to the shell body 31 , and a plurality of elastic pieces (reference numerals not shown) convexly protrude to the outside of the shell body 31 . The contact piece 34 is in close contact with the inside of the insertion hole 21 to generate a frictional force between the shell body 31 and the housing 20 . The close contact piece 34 reduces vibrations and minute movements that may occur in the shield shell 30 fixed in the insertion hole 21 .

At least one ground leg 35 is formed at the front end of the shell body 31 . The ground leg 35 is formed at the front end opposite to the side where the anti-rotation slit 32 is formed. The ground leg 35 is formed by bending a cantilever-shaped metal plate to have elasticity. The ground leg 35 may be formed of the same material as the shell body 31 and may be formed integrally with the shell body 31 or may be formed separately and fixed to the shell body 31 .

5 and 9 , the ground leg 35 includes a pressing part 35a, a contact part 35b, and a deformable part. The pressing part (35a) is formed at the farthest position from the shell body (31), and is pressed by the rear holder (40) coupled to the housing (20). It is preferable that the pressing portion 35a has a surface on which a force acts so as to be easily pressed by the rear holder 40 in a direction perpendicular to the longitudinal direction of the housing 20 .

As shown in FIG. 9 , the contact part 35b contacts the crimp ring 17 and is grounded. The contact portion (35b) is bent to face the central axis (C) of the shell body (31). The contact portion 35b is moved in a direction toward the central axis C by the force applied to the pressing portion 35a. The contact portion 35b becomes an inflection point of the deformable portion.

The deformable part connects the contact part 35b and the pressing part 35a, and transmits the force applied to the pressing part 35a over the entire ground leg 35 . The deformable portion includes a first deformable portion 35c and a second deformable portion 35d.

The first deformable portion 35c connects the shell body 31 and the contact portion 35b. The first deformable portion 35c supports the weight of the ground leg 35 and moves the contact portion 35b together with the second deformable portion 35d in the central axis line C direction. The distance between the contact part 35b and the crimping ring 17 is adjusted according to the length of the extension of the first deformable part 35c.

The second deformable portion 35d connects the contact portion 35b and the pressing portion 35a. The second deformable portion 35d is elastically deformed by the force applied to the pressing portion 35a to move the contact portion 35b in the central axis line C direction.

Referring to FIG. 2 , the rear holder 40 is coupled to the rear surface of the housing 20 . The rear holder 40 is finally coupled to the housing 20 to which the terminal 15 to which the wire 10 is coupled and the shield shell 30 are coupled to secure the terminal 15 and the shield shell 30 to the terminal 15 and the shield shell 30. It is completely fixed inside the housing (20). Also, referring to FIG. 9 , the connector of the present invention is grounded by contacting the shield shell 30 with the crimping ring 17 as the rear holder 40 is coupled to the housing 20 .

In this embodiment, the ground leg 35 is composed of one contact portion 35b and two deformable portions, but is not limited thereto, and may be implemented in variously changed shapes, for example, two or more contact portions ( 35b) and three or more deformable parts.

Referring to FIG. 6 , the rear holder 40 is made of a resin material and includes a base 41 and a side wall 43 . The base 41 has a flat plate shape and shields the rear surface of the housing 20 . A wire hole 42 is formed in the base 41 . The wire 10 is passed through the wire hole 42 .

The rear holder 40 shown in FIG. 6 is manufactured in two pieces having the same shape and is coupled to each insertion hole 21 . The rear holder 40 may be manufactured in a single piece and may be manufactured in a shape that simultaneously shields the plurality of insertion holes 21 .

A side wall 43 is formed along an edge of the base 41 . Since the side wall 43 is formed to surround a portion of the outer surface of the housing 20 , the rear holder 40 is coupled to surround the rear surface of the housing 20 . A fixing portion 44 is formed on the sidewall 43 so that a portion of the sidewall 43 is caught on the outer surface of the housing 20 . The fixing part 44 may be formed in a snap-fit structure and be fixed by being hooked on the outer surface of the housing 20 .

A pressing protrusion 45 protrudes from the base 41 along the edge of the wire hole 42 . The pressing protrusions 45 protrude parallel to the coupling direction of the rear holder 40 , and are formed in numbers corresponding to positions corresponding to the ground legs 35 of the shield shell 30 . The pressing protrusion 45 presses the ground leg 35 of the shield shell 30 while the rear holder 40 is coupled to the housing 20 .

Next, the assembly process of the connector constituting the preferred embodiment of the present invention will be described.

2 and 3, the end of the wire 10 is formed such that the center line 11, the inner insulation layer 12, the shield wire 13, and the outer insulation layer 14 are sequentially exposed, and a support ring (16) is fitted to the wire (10) so as to surround the outer insulating layer (14). The shield wire 13 of the wire 10 is bent to cover the outer surface of the support ring 16, and the crimp ring 17 is seated thereon, so that the shield wire 13 is connected to the support ring 16 and the crimp ring. It is sandwiched between (17). When the coupling of the support ring 16 and the crimping ring 17 is completed, the terminal 15 is coupled to the center line 11 . When the wire 10 is coupled to the terminal 15 , the rear holder 40 is first coupled to the wire 10 and then pushed to the middle, and the waterproof seal 18 is adjacent to the crimping ring 17 . ) are combined. Accordingly, the terminal 15, the crimping ring 17, the waterproof seal 18, and the rear holder 40 are sequentially positioned on the wire 10 from the tip. The assembly of the wire assembly (not shown) is completed by the above process.

The shield shell 30 is inserted into the insertion hole 21 of the housing 20 . The shield shell 30 is inserted into the insertion hole 21 after the front end on which the anti-rotation slit 32 is formed faces the insertion hole 21 . In the shield shell 30 inserted into the insertion hole 21, the front end of the shell body 31 is caught by the locking end 22, and movement in the insertion direction is stopped, and the rotation prevention rib 23 is rotated. It is coupled to the prevention slit 32 to prevent the shield shell 30 from rotating with the central axis C as the rotation axis.

On the other hand, although not shown, the locking piece 33 formed in the shell body 31 is hooked on the inner surface of the insertion hole 21 to prevent the shield shell 30 from escaping from the insertion hole 21 . and the close contact piece 34 is in close contact with the inner surface of the insertion hole 21 to prevent a minute movement that may occur in the shield shell 30, so that the shield shell 30 is placed on the inner surface of the insertion hole 21. completely fixed

In the process of inserting the wire assembly into the housing 20, as shown in FIG. 7, the ground leg 35 and the crimp ring 17 of the shield shell 30 are inserted with a predetermined distance apart. . Accordingly, the insertion force is reduced as much as the frictional force that would have acted when the contact portion 35b of the grounding leg 35 and the crimping ring 17 were in contact with each other, so that the relatively stable coupling of the housing 20 and the wire assembly is possible. there is At this time, since the contact portion 35b and the crimp ring 17 are spaced apart from each other by a predetermined distance, they are not grounded.

Referring to FIG. 8 , the rear holder 40 on the outer surface of the wire 10 is coupled to the rear surface of the housing 20 . The pressing protrusion 45 of the rear holder 40 passes through the through hole 19 of the waterproof seal 18 and moves toward the pressing portion 35a of the ground leg 35 . At this time, until the tip of the pressing protrusion 45 and the pressing portion 35a come into contact with each other, the contact portion 35b and the crimping ring 17 are spaced apart from each other by a predetermined distance, so the grounding state is maintained.

When the rear holder 40 is completely coupled to the rear surface of the housing 20 , the pressing protrusion 45 presses the pressing portion 35a. As shown in FIG. 9, when the pressing part 35a is pressed by the pressing protrusion 45, the contact part 35b moves toward the central axis C and comes into contact with the crimp ring 17, so it is grounded. do.

Specifically, since the first deformable part 35c and the second deformable part 35d extend toward the central axis C, when the pressing part 35a receives a pressing force, the first deformable part 35c) And the second deformable portion (35d) is deformed to be biased toward the central axis (C), the contact portion (35b) is moved toward the central axis (C). That is, in the connector of this embodiment, after the installation of the wire assembly is completed, the rear holder 40 is coupled to the housing 20 and at the same time the shield shell 30 and the crimp ring 17 are in contact and are grounded. The insertion force is reduced.
