1 to 10, a connector assembly 10 according to an embodiment may include a mating structure 11 and a connector 100 fastenable to the mating structure 11. As shown in Fig.

The mating structure 11 can be formed in a product including electronic devices such as, for example, automobiles. The mating structure 11 may be formed at a portion where electrical connection is required. The mating structure 11 includes a first fixing means 11a capable of being fixed to the connector 100, an insertion wall 11b for accommodating at least a part of the connector 100, and a mating terminal 11c disposed therein . For example, the first fixing means 11a may be a protrusion formed on a side surface of the insertion wall 11b.

The connector 100 may be physically and electrically fastened to the mating structure 11. The connector 100 includes an outer housing 110, an inner housing 120, a connection terminal 130, a wire 140, a damper 150, a wire seal 170, a position assurance member 180, ).

The outer housing 110 can be fastened to the mating structure 11. The outer housing 110 includes an inner housing insertion space into which the inner housing 120 can be inserted, a first wire insertion hole 112 in communication with the inner housing insertion space and into which the wire 140 can be inserted, And a fastening protrusion 118 protruding toward the base 120. The wire 140 may pass through the first wire insertion hole 112 and be fastened to the inside of the outer housing 110. The outer housing 110 can be fastened to the mating structure 11 with the inner housing 120 fastened thereto. A detailed description of the fastening process will be given later.

The inner housing 120 is located inside the outer housing 110, and the connection terminal 130 can be inserted into the inner housing 120. The inner housing 120 includes a second wire insertion hole 122, an engagement portion 124, a mounting body 126, a fixed body 127, an insertion portion 128 (see Figs. 6 and 8), and a projection 129 , Figs. 6 and 8).

The second wire insertion hole 122 may be formed along the longitudinal direction of the inner housing 120. The wire 140 may pass through the first wire insertion hole 121 and the second wire insertion hole 122 and may be fastened to the inner side of the inner housing 120.

The mounting body 126 may be mounted on the inside of the mating structure 11. For example, the mounting body 126 may have a shape corresponding to the insertion wall 11b of the mating structure 11.

The fixed body 127 may be mounted on the inner side of the outer housing 110. The fixed body 127 may include a through hole 1271 formed under the protrusion 129.

The protruding portion 129 can contact the inner wall of the outer housing 110 when the fixed body 127 is mounted inside the outer housing 110. The projecting portion 129 can be elastically deformed toward the through hole 1271 by the inner wall of the outer housing 110. For example, the protrusion 129 may protrude from the outer circumferential surface of the fixed body 127 toward the outer housing 110, and while the fixed body 127 is mounted inside the outer housing 110, The height can be reduced. The resiliently deformed protrusion 129 can fix the fixed body 127 to the inner side of the outer housing 110. In other words, the inner housing 120 can be fixed to the inside of the outer housing 110 by the protrusion 129 without a separate damper.

A plurality of protrusions 129 may be formed along the outer circumferential surface of the fixed body 127. The protruding portions 129 are disposed on the upper surface and the lower surface of the fixed body 127 so as to prevent the fixed body 127 from shaking in the up and down directions. So that the fixed body 127 can be prevented from swaying in the lateral direction. The protrusion 129 may be formed in a direction parallel to the longitudinal direction of the fixed body 127.

The protruding portion 129 may have a shape that becomes narrower toward the outer housing 110. For example, the protruding portion 129 may have a cross-sectional area gradually narrower from the outer circumferential surface of the fixed body 127 toward the inner wall of the outer housing 110 vertically. For example, the cross-sectional shape of the protruding portion 12 may be a triangle having one vertex pointed to the outer housing 110 when cut in the direction perpendicular to the longitudinal direction of the protruding portion 129. According to this configuration, the inner housing 120 can be aligned inside the outer housing 110 without a separate intermediate member, and the contact area of the inner wall between the protruding portion 129 and the outer housing 110 is reduced, The vibration transmitted from the outer housing 110 to the inner housing 120 through the protrusion 129 can be reduced.

The through hole 1271 may be formed under the protrusion 129. The through holes 1271 may be formed in a direction parallel to the longitudinal direction of the fixed body 127. In other words, the through hole 1271 and the protruding portion 129 can be arranged side by side. The elasticity of the protruding portion 129 can be increased by the through hole 1271. The projecting portion 129 may be formed of the same material as the fixed body 127, for example.

The connection terminal 130 can be physically and electrically fastened to the mating terminal 11c when the connector 100 is fastened to the mating structure 11. The connection terminal 130 can fix the wire 140 in a form of wrapping the wire 140. The mating terminal 11c and the wire 140 can be connected via the connection terminal 130. [ The connection terminal 130 may be located inside the inner housing 120 through the second wire insertion hole 122.

The wire 140 may be connected to the connection terminal 130. One end of the wire 140 may be connected to the connection terminal 130 and the other end may extend outside the outer housing 110. A wire seal 170 that surrounds the wire 140 may be provided outside the wire 140.

The damper 150 can separate the inner housing 120 from the outer housing 110. [ According to the damper 150, the vibration transmitted from the outer housing 110 to the inner housing 120 can be blocked or reduced. The damper 150 includes a first damper 152 disposed between the inner housing 120 and the mating structure 11 and a second damper 152 disposed between the outer housing 110 and the inner housing 120 and the mating structure 11 A second damper 154 may be included.

The first damper 152 can be inserted outside the inner housing 120. The first damper 152 can prevent the inner housing 120 from swinging inside the mating structure 11. The first damper 152 may be an annular shape formed along the periphery of the inner housing 120. The first damper 152 can prevent water, dust, and the like from entering the external structure 11 and the inner housing 120 from the outside. In consideration of such a functional aspect, the first damper 152 may be referred to as a housing sealing member.

The second damper 154 may have an annular shape surrounding the inner housing 120. The second damper 154 can prevent water, dust, or the like from entering between the mating structure 11 and the outer housing 110. Dust and the like may be generated due to friction between the mating structure 11 and the outer housing 110. According to the second damper 154, Can be prevented from being introduced.

The second damper 154 includes a first portion 154a disposed between the mating structure 11 and the outer housing 110 and a second portion 154b fixed around the inner housing 120 . When the mating structure 11, the outer housing 110 and the inner housing 120 are completely fastened, the first portion 154a is compressed so that the strain of the first portion 154a is greater than the strain of the second portion 154b. Lt; / RTI > For example, the thickness of the first portion 154a may be greater than the thickness of the second portion 154b. Therefore, the vibration transmitted from the outer housing 110 to the second damper 154 is transmitted to the relative structure 11 through the first portion 154a and the vibration transmitted to the inner housing 120 through the second portion 154b. Can be sufficiently reduced.

The first portion 154a and the second portion 154b can be understood as the outer side and the inner side of the second damper 154, respectively. In other words, the outer side of the second damper 154 is pressed by the outer housing 110 and the mating structure 11, and the inner side of the second damper 154 is inserted into the groove formed around the inner housing 120 . The strain of the outside of the second damper 154 may be sufficiently higher than the strain of the inside of the second damper 154 in a state in which the relative structure 11, the outer housing 110 and the inner housing 120 are completely engaged have. The thickness of the outside of the second damper 154 may be thicker than the thickness of the inside.

The wire seal 170 may wrap the wire 140. For example, the wire seal 170 may be in the form of a tube surrounding the wire 140. The wire seal 170 may include a rib 171 provided at the front side and a fastening portion 172 provided at the rear side with respect to a direction in which the wire 140 is inserted into the inner housing 120.

The rib 171 contacts the inner wall of the inner housing 120 to prevent foreign matter from entering from the outside. For example, the ribs 171 may have an annular shape surrounding the outer circumferential surface of the wire 140, and a plurality of ribs 171 may be provided at predetermined intervals. The rib 171 is formed of an elastically deformable material so that when the wire seal 170 is inserted into the inner housing 120, the rib 171 is elastically deformed to fill the space between the inner housing 120 and the wire 140 have. The ribs 171 can have a shape that can be easily deformed. For example, the ribs 171 may have a shape in which the cross-sectional area decreases as the portion of the ribs 171 contacts the inner wall of the inner housing 120.

The fastening portion 172 is inserted between the periphery of the wire 140 and the inner wall of the outer housing 110 to securely fix the wire 140 to the first wire insertion hole 112 of the outer housing 110 have.

For example, the fastening portion 172 may be elastically deformed by contacting the inner wall of the inner housing 120 and the inner wall of the outer housing 110. For example, the front portion of the fastening portion 172 may be elastically deformed by contacting the inner wall of the inner housing 120, with the wire 140 inserted in the inner housing 120, 172 may contact the inner wall of the outer housing 110 and may be resiliently deformed. A portion contacting the inner housing 120 is referred to as a first contact portion 172a and a portion contacting the inner housing 110 is referred to as a second contact portion 172b.

The fastening portion 172 may include a shape having a larger cross-sectional area as the wire 140 extends outwardly of the outer housing 110. For example, the cross-sectional area of the second contact portion 172b may be larger than the cross-sectional area of the first contact portion 172a. A cross-sectional area of an end portion of the fastening portion 172 extending to the outside of the outer housing 110 may be larger than an area of the first wire insertion hole 112. For example, the second contact portion 172b may be larger than the area of the first wire insertion hole 112 of the outer housing 110 as a whole, and may be elastically deformed by being pressed by the inner wall of the outer housing 110. On the other hand, the cross-sectional area of the opposite end of the fastening portion 172 may be smaller than the area of the second wire insertion hole 122. For example, the front end of the first contact portion 172a may be smaller than the area of the second wire insertion hole 122 of the inner housing 120, and the first contact portion 172a may be easily located inside the inner housing 120 Lt; / RTI >

Since the wire seal 170 has a shape in which the sectional area becomes larger as the wire seal 170 moves backward, the strain of the second contact portion 172b is lower than the strain of the second contact portion 172b in a state where the wire 140 is fastened to the inner housing 120 and the outer housing 110 1 contact portion 172a. The wire seal 170 may be formed of the same material as the whole and the ratio of the deformation length to the initial length of the second contact portion 172b may be larger than the ratio of the deformation length to the initial length of the first contact portion 172a. The second contact portion 172b may be stiffer than the first contact portion 172a. In this case, the vibration transmitted from the outside to the wire 140 is transmitted from the outside to the inner housing 120 through the wire 140 by allowing the vibration to be mostly transmitted to the outer housing 110 through the second contact portion 172b Vibration can be reduced.

The position assurance member 180 is inserted into the engagement portion 124 of the inner housing 120 to prevent the connection terminal 130 from being detached from the inner housing 120. [

The fixing lever 190 can improve the coupling force between the outer housing 110 and the mating structure 11. [ The fixing lever 190 can be removed from the outer housing 110. The fixing lever 190 may include a hook 192 disposed on the opposite side of the first fixing means 11a with respect to the second fixing means 116 while being coupled to the outer housing 110. [ The fixing lever 190 can increase the coupling force between the outer housing 110 and the mating structure 11 by interfering with the separation of the second fixing means 116 from the first fixing means 11a.

Referring to FIGS. 8 and 9, the process of fastening the mating structure 11, the outer housing 110, and the inner housing 120 will be described.

The housing of any one of the outer housing 110 and the inner housing 120 includes a fastening protrusion 118 protruding toward the other housing and the other housing includes a fastening protrusion 118 And an inserting portion 128 for inserting the inserter. 8 illustrates an example in which the fastening protrusion 118 is formed in the outer housing 110 and the insertion portion 128 is formed in the inner housing 120. As shown in FIG.

The end of the fastening protrusion 118 may be disposed apart from the bottom surface of the insertion portion 128. [ The length of the insertion portion 128 may be longer than the length of the fastening protrusion 118 with respect to the direction in which the inner housing 120 is inserted into the outer housing 110. [ According to this structure, depending on the length of insertion of the inner housing 120 into the outer housing 110, the fastening protrusion 118 may interfere with the inner side wall of the insertion portion 128, Can be spaced apart from all the inner walls of the insert 128.

8, when the wire 140 to which the wire seal 170 is attached is inserted in a state where the outer housing 110 and the inner housing 120 are fastened together, the wire seal 170 is deformed by the shape of the wire seal 170, The fastening protrusion 118 can be interfered with the inner wall of the insertion portion 128 as the fastening protrusion 120 is pushed. The wire seal 170 is attached to the first wire insertion hole 112 by pressing the wire seal 170 with sufficient force in a state where the inner housing 120 is prevented from being separated from the outer housing 110. [ .

9, when the mating structure 11 and the outer housing 110 are fastened together, the mating structure 11 and the outer housing 110 are separated from each other by the mating structure 11, The housing 120 is pushed out. The inner housing 120 is pushed into the outer housing 110 so that the portions 118 and 128 that fasten the outer housing 110 and the inner housing 120 are connected to each other as shown in the enlarged view of FIG. The inner housing 120 is in a floating state with respect to the outer housing 110 except for a contact point between the protruding portion 129 of the inner housing 120 and the inner wall of the outer housing 110 .

Also, the wire seal 170 is pressed in the direction in which the inner housing 120 moves, and as a result, the strain of the second contact portion 172b of the wire seal 170 can be increased. That is, the rigidity of the second abutting portion 172b can be increased, the vibration transmitted to the outer housing 110 is increased, and the vibration transmitted to the inner housing 120 is reduced can do.

10, a vibration path that is transmitted along the wire 140 from the outside in a state where the connector 100 and the mating structure 11 are fully engaged will be described.

The vibration transmitted from the outside along the wire 140 is transmitted along the outer housing 110 through the second contact portion 172b of the fastening portion 172 fixed to the wire 140 with a sufficient coupling force, 110 to the mating structure 11. On the other hand, according to the protrusion 129, the vibration transmitted from the outer housing 110 to the inner housing 120 can be reduced.

According to such a vibration path, the influence of the vibration on the connection terminal 130 disposed inside the connector 100 can be drastically reduced. Therefore, the connection terminal 130 can exhibit a normal function even in a high-vibration state such as a space where the engine is installed, so that the stability of the product can be improved and the life cycle can be increased.

11 is a perspective view of an inner housing according to an embodiment.

11, the inner housing 220 includes a second wire insertion hole 222, an engagement portion 224, a mounting body 226, a fixed body 227, an insertion portion 228, a protrusion portion 229, And a separation groove 225. [

The protrusion 229 may include a first sub-protrusion 229a and a second sub-protrusion 229b that are spaced apart in the longitudinal direction of the fixed body 227.

The first sub protruding portion 229a and the second sub protruding portion 229b can be elastically deformed by contacting the inner wall of the outer housing 110 (see FIG. 1).

The separation groove 225 may be formed between the first sub-projection 229a and the second sub-projection 229b. At a portion where the separation groove 225 is formed, the fixed body 227 may be spaced apart from the outer housing 110. The separation groove 225 can increase the elasticity of the first sub protruding portion 229a and the second sub protruding portion 229b. Since the separation groove 225 can reduce the contact area of the inner housing 220 with the outer housing 110, it is possible to reduce the vibration transmitted from the outer housing 110 to the inner housing 220 have.

FIG. 12A is a side view of the wire seal according to an embodiment, FIG. 12B is a sectional view of the wire seal according to an embodiment, and FIG. 12C is a view showing a stress distribution diagram of the wire seal shown in FIGS. 12A and 12B.

12A to 12C, the wire seal 270 has ribs 271 provided on the front side in the direction in which the wire 140 (see FIG. 1) is inserted into the inner housing 120 (see FIG. 1) And a separating part 273 disposed between the rib 271 and the fastening part 272. The fastening part 272 is provided with a fastening part 272, The fastening portion 272 may include a first contact portion 272a and a second contact portion 272b.

For example, the maximum diameter of the separating portion 273 may be smaller than the inner diameter of the second wire insertion hole 122 (see FIG. 1) of the inner housing 120. According to this structure, the separating portion 273 can be separated from the inner wall of the inner housing 120 with the connector assembly fully engaged.

For example, the separator 273 may include a first vibration isolation groove 273a formed in a portion adjacent to the rib 271, a second vibration isolation groove 273b formed in a portion adjacent to the coupling portion 272, And a separation body 273c formed between the first vibration isolation groove 273a and the second vibration isolation groove 273b. For example, the width of the first and second vibration isolation grooves 273a and 273b may be smaller than the width of the separation body 273c. According to this structure, it is possible to suppress transmission of vibration between the rib 271 that performs the waterproof function and the coupling portion 272 that performs the function of fixing the wire. Specifically, the vibration at the first contact portion 272a can be reduced again in the process of passing through the second vibration isolation groove 273b, and after being partially absorbed by the separation body 273c, the vibration of the first vibration isolation groove 273a ) Can be reduced again in the course of passing. The above vibration blocking effect can also be confirmed through the stress distribution diagram of FIG. 12C.
