Description

Technical Field

[0001] The present invention relates to a shielded connector. Background Art

[0002] Conventionally, a shielded connector that uses a metal inner case and outer case for shielding has been known (for example, refer to Patent Document 1 below).

[0003] Conventional shielded connectors, for example, as Figure 19 and Figure 20 shown, include a rear case (5: cover case) that contacts both the front case (4: inner case) and the outer case (7: outer case). Further, in this conventional example, there is a structure in which the bent piece (51) of the rear case (5) contacts the side surface of the front case (4) from the outside, and the spring piece (55) of the rear case (5) contacts the side surface of the outer case (7) from the inside.

[0004] It should be noted that the reference numerals related to the description of the prior art documents are distinguished from the embodiments of the present invention by enclosing them in parentheses.

[0006] Patent Documents

[0007] Patent Document 1: Japanese Patent Application Laid-Open No. 2005-38725

[0008] However, in the structure of the conventional shielded connector disclosed in Patent Document 1 above, the ground conduction path from the front case (4) to the outer case (7) detours through the entire lengths of the bent piece (51) and the spring piece (55), so the ground conduction path is long, and there is a problem of low shielding performance. In addition, in the structure of the conventional example, the bent piece (51) and the spring piece (55) are arranged side by side on the side surface of the rear case (5), so the occupied area of the bent piece (51) and the spring piece (55) on the side surface of the rear case (5) is large, and there is also a structural problem that it is difficult to increase the number of the bent piece (51) and the spring piece (55) to enhance the shielding performance. Summary of the Invention

[0009] Problems to be Solved by the Invention

[0010] Accordingly, an object of the present invention is to provide a shielded connector having higher shielding performance than the prior art.

[0011] Means for Solving the Problems

[0012] The shielded connector of the present invention includes: a metal inner shell disposed in the inner housing; a metal outer shell disposed in the outer housing; and a metal cover shell that contacts both the inner shell and the outer shell. It is characterized in that the inner shell, the outer shell, and the cover shell each have contact joint portions, and the joint portion of the cover shell is inserted between the joint portion of the inner shell and the joint portion of the outer shell.

[0013] That is, in the shielded connector of the present invention, the joint portion of the cover shell is inserted between the joint portion of the inner shell and the joint portion of the outer shell. Therefore, the joint portions of the three components all overlap at the same position, and the path length of the ground conduction path is shortened because it is in the thickness direction of the joint portion, and the occupied area of the joint portion can also be reduced.

[0014] In addition, in the shielded connector of the present invention, it may be that each joint portion included in the inner shell, the outer shell, and the cover shell is formed by any one of three shape portions: an elastic spring plate-shaped portion, a protrusion-shaped portion protruding toward the contact side, and a flat plate-shaped portion in a flat plate shape. The joint portion of the cover shell is inserted between the joint portion of the inner shell and the joint portion of the outer shell.

[0015] In addition, in the shielded connector of the present invention, it may be that either the joint portion of the inner shell or the joint portion of the outer shell is an elastic spring plate-shaped portion, the other of the joint portion of the inner shell and the joint portion of the outer shell is a protrusion-shaped portion protruding toward the contact side, and the joint portion of the cover shell is a flat plate-shaped portion in a flat plate shape.

[0016] In addition, in the shielded connector of the present invention, it may be that the joint portions of both the joint portion of the inner shell and the joint portion of the outer shell are elastic spring plate-shaped portions, and the joint portion of the cover shell is a flat plate-shaped portion in a flat plate shape.

[0017] In addition, in the shielded connector of the present invention, it may be that the joint portions of both the joint portion of the inner shell and the joint portion of the outer shell are flat plate-shaped portions in a flat plate shape, and the joint portion of the cover shell is an elastic spring plate-shaped portion.

[0018] In addition, in the shielded connector of the present invention, it may be that either the joint portion of the inner shell or the joint portion of the outer shell is an elastic spring plate-shaped portion, the other of the joint portion of the inner shell and the joint portion of the outer shell is a flat plate-shaped portion in a flat plate shape, and the joint portion of the cover shell is a protrusion-shaped portion protruding toward the contact side.

[0019] Also, in the shielded connector of the present invention, it is possible that the spring plate-shaped portion is a spring piece in the shape of a cantilever beam extending from the rear to the front of the shielded connector, the flat plate-shaped portion is a flat plate extending from the rear to the front of the shielded connector, and the contact portion of the cover is inserted from the rear of the shielded connector between the contact portion of the inner housing and the contact portion of the outer housing.

[0020] In addition, in the shielded connector of the present invention, it is possible that the inner housing has: two side surfaces, each of which has at least one contact portion; and a top surface, which has at least one contact portion, the outer housing has: two side surfaces, each of which has at least one contact portion; and a top surface or a rear surface, which has at least one contact portion, and the cover has: two side surfaces, each of which has at least one contact portion; and a top surface, which has at least one contact portion.

[0021] Also, in the shielded connector of the present invention, it is possible that the outer housing has a rear surface, which has at least one contact portion and covers the upper half of the outer housing, and the cover has a rear surface covering the lower half of the outer housing.

[0022] Advantages of the Invention

[0023] According to the present invention, it is possible to obtain a shielded connector with improved shielding performance by shortening the path length of the ground conduction path. In addition, in the shielded connector according to the present invention, the occupied area of the contact portion is small, so it is easy to increase the number of contact portions to enhance the shielding performance.

[0085] Hereinafter, preferred implementation manners for implementing the present invention will be described with reference to the drawings. It should be noted that the following implementation manners do not limit the invention in each technical solution, and in addition, the combinations of the features described in the implementation manners are not necessarily all essential for the solution of the invention.

[0086] As Figure 10 shown, the shielded connector 10 of the present implementation manner includes, as main structural members: a resin-made outer housing 110; a metal-made outer shell 210 provided on the outer housing 110; an inner terminal portion 310 provided on the outer housing 110; and a metal-made cover shell 410 disposed in a manner of covering the inner terminal portion 310 on the outer housing 110 where the inner terminal portion 310 is provided.

[0087] In addition, as Figure 11 shown, the inner terminal portion 310 of the present implementation manner includes: a resin-made inner housing 320; a metal-made inner shell 330 provided on the outer side of the inner housing 320; and a metal terminal 340 inserted and provided inside the inner housing 320.

[0088] In the shielded connector 10 of the present embodiment, as Figures 6 to 9 shown, by including a metal outer shell 210 provided on the outer housing 110, and a metal cover 410 that contacts both the inner shell 330 and the outer shell 210, the function of the shielded connector 10 having shielding performance is exhibited.

[0089] Referring to Figures 1 to 5 , the shielded connector 10 of the present embodiment electrically connects the shielded connector 10 of the present embodiment and the corresponding-side connector by inserting a corresponding-side connector (not shown) into an opening that opens on the front side. In addition, the shielded connector 10 of the present embodiment can be connected to circuit wiring formed on the substrate surface, for example, by fixing the bottom surface side of the shielded connector 10 to the upper surface of a substrate (not shown).

[0090] It should be noted that, in the present embodiment, for convenience of explanation, a first direction, a second direction, and a third direction are defined. In the present embodiment, the first direction is the front-rear direction. In the figure, the front-rear direction is represented as the X direction. In particular, the front is set as the +X direction, and the rear is set as the -X direction. In addition, in the present embodiment, the second direction is the left-right direction. In the figure, the left-right direction is represented as the Y direction. In particular, the right is set as the +Y direction, and the left is set as the -Y direction. And, in the present embodiment, the third direction is the up-down direction. In the figure, the up-down direction is represented as the Z direction. In particular, the upper side is set as the +Z direction, and the lower side is set as the -Z direction.

[0091] As Figure 10 shown, the outer housing 110 of the present embodiment is a resin member having an opening that penetrates in a direction parallel to the first direction, i.e., the X direction. By inserting the inner terminal portion 310 from the rear to the front of the outer housing 110, the inner terminal portion 310 can be provided inside the opening of the outer housing 110. In addition, by inserting the outer shell 210 from the upper side to the lower side of the outer housing 110, the outer shell 210 can be provided so as to cover the upper side and the upper half of the back surface of the outer housing 110. Further, by inserting the cover 410 from the rear to the front of the outer housing 110, the cover 410 can be provided so as to cover the back side of the inner terminal portion 310 and the lower half of the back surface of the outer housing 110 (also refer to Figures 1 to 5 ).

[0092] As Figure 12 shown, the outer shell 210 of the present embodiment has two side surfaces 211, one top surface 212, and one rear surface 213.

[0093] Below the lower sides of the two side surfaces 211 that make up the outer shell 210, three legs 214, a total of six legs, are respectively formed on each side surface 211. By inserting and pressing the six legs 214 downward in the -Z direction from above the outer housing 110, the outer shell 210 is fixed relative to the outer housing 110. In addition, the six legs 214 can be used when fixing and connecting the bottom surface side of the shielded connector 10 to the upper surface of a substrate (not shown) or the like.

[0094] Spring plate-shaped portions 215, which are contact portions that come into contact with the cover 410, are formed below the rear side of each of the two side surfaces 211 and the lower side of one rear surface 213 that make up the outer shell 210. Among the two side surfaces 211, two spring plate-shaped portions 215 are formed on the right side surface 211R, and two spring plate-shaped portions 215 are formed on the left side surface 211L. In addition, two spring plate-shaped portions 215 are formed below the rear surface 213. That is, a total of six spring plate-shaped portions 215 are formed on the outer shell 210 of the present embodiment.

[0095] The six spring plate-shaped portions 215 formed on the outer shell 210 are formed as cantilever spring pieces that extend from the rear to the front of the shielded connector 10. More specifically, as Figures 6 to 9 , Figure 12 shown, among the two side surfaces 211, the root of a rectangular slice that extends rearward from the rear sides of the left and right side surfaces 211L and 211R is bent inwardly of the outer shell 210 so that the front end side of the slice faces forward and is substantially J-shaped in plan view, thereby forming the spring plate-shaped portion 215 of the present embodiment. In addition, in one rear surface 213, the root of a rectangular slice that extends downward from the lower side is bent inwardly of the outer shell 210 so that the front end side of the slice faces forward and is substantially J-shaped or substantially L-shaped in side view, thereby forming the spring plate-shaped portion 215 of the present embodiment. The spring plate-shaped portion 215 of the present embodiment has an outer shape that is substantially J-shaped or substantially L-shaped, so that the spring plate-shaped portion 215 as a contact portion can exert an elastic force.

[0096] As Figure 11As shown, the inner housing 320 that constitutes the inner terminal portion 310 of the present embodiment is a resin member having a substantially rectangular shape. By inserting the metal terminal 340 from the rear toward the front into the inner housing 320 of the present embodiment, the metal terminal 340 can be provided in the inner housing 320. The metal terminal 340 is a member used, for example, for connecting to circuit wirings formed on a substrate surface when the bottom surface side of the shielded connector 10 is fixedly connected to the upper surface of a substrate (not shown). In addition, by inserting the inner shell 330 from the front toward the rear into the inner housing 320 of the present embodiment, the inner shell 330 can be provided so as to cover the outer peripheral surface of the inner housing 320.

[0097] As Figure 11 and Figure 13 shown, the inner shell 330 of the present embodiment is a metal member having an opening that penetrates in a direction parallel to the first direction, i.e., the X direction. By inserting the inner shell 330 from the front toward the rear of the inner housing 320, the inner housing 320 can be provided inside the opening of the inner shell 330.

[0098] Protrusion-shaped portions 335 serving as contact portions that come into contact with the cover case 410 are formed on each of the left and right side surfaces 331 and one top surface 333 that constitute the inner shell 330. Among the two side surfaces 331, two protrusion-shaped portions 335 are formed on the right side surface 331R, and two protrusion-shaped portions 335 are formed on the left side surface 331L. In addition, two protrusion-shaped portions 335 are formed on the top surface 333. That is, a total of six protrusion-shaped portions 335 are formed on the inner shell 330 of the present embodiment.

[0099] The six protrusion-shaped portions 335 formed on the inner shell 330 are portions formed as protrusions that protrude toward the side where contact is made, i.e., the side that comes into contact with the cover case 410.

[0100] As Figure 10 and Figure 14 shown, the cover case 410 of the present embodiment has two side surfaces 411, one top surface 412, and one rear surface 413. Flat plate-shaped portions 415 serving as contact portions that come into contact with the inner shell 330 and the outer shell 210 are formed above and below each of the two side surfaces 411 and on the right and left sides of one top surface 412. Among the two side surfaces 411, two flat plate-shaped portions 415 are formed on the right side surface 411R, and two flat plate-shaped portions 415 are formed on the left side surface 411L. In addition, two flat plate-shaped portions 415 are formed on the top surface 412. That is, a total of six flat plate-shaped portions 415 are formed on the cover case 410 of the present embodiment.

[0101] The six flat-shaped portions 415 formed on the housing 410 of the present embodiment as contact portions are portions of a plate member in a flat plate shape configured to extend forward from the rear of the shielded connector 10, and are inserted and sandwiched between the spring plate-shaped portion 215 and the protrusion-shaped portion 335, which are contact portions provided in the inner housing 330 and the outer housing 210 respectively, thereby achieving the contact state among the inner housing 330, the outer housing 210, and the housing 410. Additionally, at this time, through the combined action of the elastic force of the spring plate-shaped portion 215 and the protrusion shape of the protrusion-shaped portion 335, a reliable contact state among the inner housing 330, the outer housing 210, and the housing 410 is maintained.

[0102] And, referring to Figure 7 and Figure 9 it can be clearly seen that the positions where the spring plate-shaped portion 215 of the outer housing 210, the protrusion-shaped portion 335 of the inner housing 330, and the flat-shaped portion 415 of the housing 410 come into contact are configured to be close positions. According to this structure, by setting the ground conduction path in the thickness direction of the contact portion, the path length can be shortened to obtain a shielded connector with improved shielding performance. Additionally, according to the spring plate-shaped portion 215 of the outer housing 210, the protrusion-shaped portion 335 of the inner housing 330, and the flat-shaped portion 415 of the housing 410 constituting the present embodiment, the occupied area of the contact portion is small, so it is, for example, easy to increase the number of contact portions. Therefore, according to the present embodiment, it is easy to increase the contact portions to enhance the shielding performance.

[0103] Referring to Figure 2 and Figure 4 , on the back side of the shielded connector 10 of the present embodiment, the outer housing 210 is provided so as to cover the upper half of the back surface, and the housing 410 is arranged so as to cover the lower half of the back surface. Here, in order to enhance the shielding performance, no gap should be generated on the back side where multiple components are connected. Thus, in the present embodiment, shielding portions 216 are formed on the rear sides of the respective two side surfaces 211 and the lower side of one rear surface 213 constituting the outer housing 210 (also refer to Figure 12 ). By forming the shielding portions 216, the outer housing 210 and the housing 410 made of a metal material cover the back side of the shielded connector 10 without a gap, so the shielding performance of the shielded connector 10 of the present embodiment can be improved.

[0104] According to the shielded connector 10 of the present embodiment described using Figures 1 to 14 , since it has a structure with improved shielding performance, a shielded connector with improved anti-interference performance can be achieved.

[0105] In addition, in the present embodiment, although the structure is such that components composed of three metal materials, namely, the spring plate-shaped portion 215 of the outer shell 210, the protrusion-shaped portion 335 of the inner shell 330, and the flat plate-shaped portion 415 of the cover shell 410, are connected, the ground connection is a multi-point connection, thereby enabling the realization of a shielded connector with enhanced anti-interference performance.

[0106] Moreover, in the present embodiment, since the structure is such that the three contact portions, namely, the spring plate-shaped portion 215 of the outer shell 210, the protrusion-shaped portion 335 of the inner shell 330, and the flat plate-shaped portion 415 of the cover shell 410, are in contact at positions close to each other, the ground conduction path is in the thickness direction of the contact portions, and a shielded connector with improved shielding performance can be obtained by shortening the path length. It should be noted that this structure also contributes to the miniaturization of the shielded connector 10.

[0107] In addition, and according to the shielded connector 10 of the present embodiment, the occupied areas of the three contact portions, namely, the spring plate-shaped portion 215 of the outer shell 210, the protrusion-shaped portion 335 of the inner shell 330, and the flat plate-shaped portion 415 of the cover shell 410, are small, so it is easy to increase the number of contact portions and strengthen the shielding performance.

[0108] Next, a summary of the manufacturing process of the shielded connector 10 of the present embodiment will be described below.

[0109] As can be understood by referring to Figure 11 For the internal terminal portion 310 of the present embodiment, two metal terminals 340 are inserted along the first direction of the internal housing 320 from the rear toward the front +X direction, thereby disposing the metal terminals 340 in the internal housing 320, and the inner shell 330 is inserted along the first direction of the internal housing 320 from the front toward the rear -X direction, thereby disposing the inner shell 330 so as to cover the outer peripheral surface of the internal housing 320, and thus the assembly is completed.

[0110] Next, as can be understood by referring to Figure 10 The internal terminal portion 310 can be disposed inside the opening of the outer housing 110 by inserting the internal terminal portion 310 along the first direction of the outer housing 110 from the rear toward the front +X direction. In addition, the outer shell 210 can be disposed so as to cover the upper part and the upper half of the back surface of the outer housing 110 by inserting the outer shell 210 from above, which is the third direction of the outer housing 110, toward the lower direction -Z direction. Moreover, the cover shell 410 can be disposed so as to cover the back side of the internal terminal portion 310 and the lower half of the back surface of the outer housing 110 by inserting the cover shell 410 from the rear, which is the first direction of the outer housing 110, toward the front +X direction. Through such a manufacturing process, the shielded connector 10 of the present embodiment is completed.

[0111] As described above, the preferred embodiments of the present invention have been described, but the technical scope of the present invention is not limited to the scope described in the above embodiments. Various changes or improvements can be made to the above embodiments.

[0112] For example, in the above embodiment, regarding the combination of the contact portions, an example is shown which is composed of a combination of three contact portions: a spring plate-shaped portion 215 formed on the outer shell 210, a protrusion-shaped portion 335 formed on the inner shell 330, and a flat plate-shaped portion 415 formed on the cover shell 410. However, for the contact portions of the present invention, any one of the three shape portions, i.e., the spring plate-shaped portion 215, the protrusion-shaped portion 335, and the flat plate-shaped portion 415, can be arbitrarily selected, and all combinations of the same type or different types of contact portions can be selected.

[0113] For example, regarding the contact portions of the inner shell 330 and the outer shell 210, both contact portions can be set as spring plate-shaped portions, and the contact portion of the cover shell 410 can be set as a flat plate-shaped portion.

[0114] In addition, for example, in Figure 15 and Figure 16 In the shielded connector 50 of the first modified embodiment shown, a structural example is shown in which a flat plate-shaped portion 515 is formed on the outer shell 510, a flat plate-shaped portion 535 is formed on the inner shell 530, and a spring plate-shaped portion 555 is formed on the cover shell 550. And by inserting the spring plate-shaped portion 555, which is the contact portion of the cover shell 550, between the flat plate-shaped portion 535, which is the contact portion of the inner shell 530, and the flat plate-shaped portion 515, which is the contact portion of the outer shell 510, the elastic force of the spring plate-shaped portion 555 comes into play, maintaining a reliable contact state among the inner shell 530, the outer shell 510, and the cover shell 550. That is, even for the combination mode of the contact portions of the shielded connector 50 of the first modified embodiment, a shielded connector with the same shielding performance as the above embodiment can be realized.

[0115] In addition, in the above embodiment, regarding the structure on the back side of the shielded connector 10, the outer shell 210 is provided so as to cover the upper half of the back surface of the outer housing 110, and the cover shell 410 is provided so as to cover the lower half of the back surface of the outer housing 110. However, regarding the structure on the back side of the shielded connector of the present invention, various modified forms can be adopted.

[0116] For example, in Figure 17 and Figure 18In the shielded connector 60 of the second modified form shown, a modified form example is shown in which the entire back surface of the shielded connector 60 is covered by the housing 650. In the case of this second modified form, it is configured such that the outer shell 610 covers the left and right side surfaces and the top surface of the outer housing 110. Further, the contact portion on the top surface side of the inner shell 630 is formed as a spring plate-shaped portion 635, and on the top surface side of the shielded connector 60, the flat plate-shaped portion 655 of the housing 650 is inserted between the spring plate-shaped portion 215 of the outer shell 610 and the spring plate-shaped portion 635 of the inner shell 630, thereby maintaining a reliable contact state among the inner shell 630, the outer shell 610, and the housing 650.

[0117] It should be noted that, in Figures 15 to 18 components that are the same as or similar to the components described in the above-described present embodiment are denoted by the same reference numerals, and thus the description thereof is omitted.

[0118] As described above, various structural examples that the shielded connector of the present invention can adopt have been described. However, it is clearly understood from the description of the patent technical solution that modes in which such various changes or improvements are made can also be included in the technical scope of the present invention.
