[0012] Figure 1 This is an exploded perspective view of a connector according to one embodiment. Figure 2 This is a top view of a connector according to one embodiment. Figure 3 It is along Figure 2 A sectional view along line 3-3. Figure 4 It is along Figure 2 A sectional view along line 4-4. Detailed Implementation

[0013] [Description of embodiments of this disclosure] The embodiments of this disclosure are first described in detail. [1] The connector disclosed herein comprises: a plurality of terminals electrically connected to and arranged side-by-side with a counterpart terminal disposed on a machine; a resin housing holding the plurality of terminals; and a metal shielding shell covering the housing and fixed to the housing of the machine, the housing having: a cylindrical portion having an opening exposing the plurality of terminals; and a protrusion protruding from the cylindrical portion toward the outer periphery of the cylindrical portion, the shielding shell having: a surrounding portion surrounding the outer periphery of the cylindrical portion; a recess disposed in the surrounding portion opposite to the protrusion and engaging with the protrusion; and a fixing portion having a through hole for inserting a bolt for fixing the shielding shell and the housing, and fixed to the housing.

[0014] According to this structure, the shielding shell is positioned on the housing by engaging with the recess of the shielding shell and the protrusion of the housing. Thus, the fixing part of the shielding shell is positioned on the machine housing. Therefore, it is easy to fix the shielding shell to the housing by inserting bolts into the through hole of the fixing part. Therefore, it is possible to prevent a decrease in workability during the assembly of the shielding shell.

[0015] [2] Preferably, when the protrusion is designated as the first protrusion, the housing has a second protrusion that protrudes from the cylindrical portion toward the outer periphery of the cylindrical portion and extends in the axial direction of the cylindrical portion.

[0016] According to this structure, because the second protrusion extends in the axial direction of the cylindrical portion, the rigidity of the cylindrical portion is improved. Therefore, for example, the formation defects in the shell, such as shrinkage marks, can be suppressed, thus improving the dimensional accuracy of the opening in the cylindrical portion.

[0017] [3] Preferably, the surrounding portion extends in the arrangement direction of the plurality of terminals, and the fixing portion is disposed on both sides of the surrounding portion in the arrangement direction. According to this structure, the fixing parts are provided on both sides in the arrangement direction of the surrounding parts. Therefore, the shielding shell is fixed to the housing on both sides in the direction in which the surrounding parts extend. This makes it easy to ensure the distance between the fixing parts. Therefore, the shielding shell can be stably fixed to the housing.

[0018] [4] Preferably, the housing has a flange extending from the cylindrical portion toward the surrounding portion, the surrounding portion covering the flange from the side opposite to the housing in the axial direction of the cylindrical portion.

[0019] According to this structure, a flange is covered from the side opposite to the housing in the axial direction of the cylindrical portion using a surrounding portion. This facilitates the positioning of the shielding shell within the housing in the aforementioned axial direction. Therefore, it further reduces the decrease in workability during the assembly of the shielding shell.

[0020] [5] Preferably, the protrusion is connected to the flange and extends to the outer edge of the flange. Based on this structure, the strength of the flange can be increased by using protrusions.

[0021] [Details of the embodiments of this disclosure] Specific examples of the connectors of this disclosure are described below with reference to the accompanying drawings. In the drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. Additionally, the dimensional ratios of the various parts sometimes differ in the drawings. Furthermore, this disclosure is not limited to these examples, but is intended by the claims to include all variations within the scope of the claims and the like. The term "orthogonal" in this specification includes not only strictly orthogonal cases, but also cases that are substantially orthogonal to the extent that they achieve the desired effect in this embodiment.

[0022] (Structure of connector 10) like Figure 1 and Figure 2As shown, connector 10 is electrically connected to vehicle machinery such as electric motors and inverters. Connector 10 is mounted in the housing 100 of the machine, which has an opening 101.

[0023] The connector 10 has a plurality of terminals 20 arranged in parallel, a housing 40 holding the plurality of terminals 20, and a shielding shell 50 covering the housing 40. The connector 10, for example, has three terminals 20. Wires 30 are electrically connected to the terminals 20. The wires 30 extend from the housing 40.

[0024] From now on, the arrangement direction of the multiple terminals 20 will be called the X-axis direction, the direction of the wires 30 extending from the housing 40 will be called the Y-axis direction, and the direction orthogonal to both the X-axis and Y-axis directions will be called the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are orthogonal to each other.

[0025] (Structure of terminal 20) like Figure 3 As shown, terminal 20 has a wire connection portion 21 and a terminal connection portion 22. Terminal 20 is a single component in which the wire connection portion 21 and the terminal connection portion 22 are formed as one piece. Terminal 20 is formed of metal materials such as copper, copper alloy, aluminum, aluminum alloy, and stainless steel.

[0026] The wire 30 is electrically connected to the wire connection portion 21. Here, the wire 30 has a core wire 31 and an insulating covering portion 32 that encloses the core wire 31. The core wire 31 protrudes from the insulating covering portion 32 at the end of the wire 30. The core wire 31 protruding from the insulating covering portion 32 is electrically connected to the wire connection portion 21.

[0027] The terminal connection portion 22 is, for example, plate-shaped. The terminal connection portion 22 extends from the wire connection portion 21 in the Y-axis direction. An insertion hole 23 is provided in the terminal connection portion 22, which passes through the terminal connection portion 22 in the Z-axis direction. The terminal connection portion 22 is electrically connected to a metal counterpart terminal 110 provided inside the opening 101 of the housing 100 by means of a bolt 120 inserted into the insertion hole 23.

[0028] (Structure of shell 40) like Figure 1 As shown, the housing 40 has a holding portion 41 for holding a plurality of terminals 20, a cylindrical portion 42 in the shape of a cylinder, and a flange 45 extending from the cylindrical portion 42 toward the outer periphery of the cylindrical portion 42. The holding portion 41, the cylindrical portion 42, and the flange 45 are integrally formed. The housing 40 is formed, for example, of a resin material.

[0029] like Figure 3 As shown, the retaining portion 41 protrudes from the cylindrical portion 42 toward the outer periphery of the cylindrical portion 42 in the Y-axis direction. The retaining portion 41 retains the connection portion of the wire connection portion 21 and the wire 30. The plurality of terminals 20 connected to the wire 30 and the housing 40 are integrated by insert molding.

[0030] like Figure 1 and Figure 2 As shown, the cylindrical portion 42 extends in the X-axis direction. The cylindrical portion 42 has an opening 43 that extends through in the Z-axis direction. The opening 43 is an elongated oval shape that is longer in the X-axis direction.

[0031] The terminal connection portion 22 of each terminal 20 is exposed from the opening 43. When viewed from the Z-axis direction, the insertion hole 23 of the terminal 20 overlaps entirely with the opening 43. like Figure 1 As shown, an insertion part 44 is provided at one end of the cylindrical part 42 in the Z-axis direction, and the insertion part 44 is inserted into the opening 101 of the housing 100. An annular sealing member 60, made of an elastic material such as rubber, is provided on the outer peripheral surface of the insertion part 44. The insertion part 44 and the opening 101 of the housing 100 are sealed by the sealing member 60.

[0032] The flange 45 extends from the portion of the cylindrical portion 42 adjacent to the insertion portion 44 in the Z-axis direction, excluding the holding portion 41. The flange 45 extends toward the surrounding portion 52 of the shielding shell 50, which will be described later. The flange 45 is connected to the holding portion 41.

[0033] like Figure 2 As shown, the housing 40 has a plurality of first protrusions 46 and a plurality of second protrusions 47 protruding from the cylindrical portion 42 toward the outer periphery of the cylindrical portion 42. The housing 40 has three first protrusions 46 and six second protrusions 47. Both the first protrusions 46 and the second protrusions 47 are plate-shaped.

[0034] The first protrusion 46 is provided at the end of the cylindrical portion 42 in the Y-axis direction opposite to the retaining portion 41, and at both ends of the cylindrical portion 42 in the X-axis direction. The first protrusion 46 is connected to the flange 45.

[0035] like Figure 1 As shown, the first protrusion 46 extends to the outer edge 45a of the flange 45. The amount by which the first protrusion 46 protrudes from the cylindrical portion 42 is the same as the amount by which the flange 45 protrudes from the cylindrical portion 42.

[0036] The length of the first protrusion 46 in the Z-axis direction is less than the length of the cylindrical portion 42 in the Z-axis direction from the flange 45 to the edge of the opening 43. In the following description, the circumferential direction of the cylindrical portion 42 will be referred to simply as the circumferential direction. One second protrusion 47 is provided on each side of the first protrusion 46 in the circumferential direction. The first protrusion 46 and the second protrusion 47 are each spaced apart from each other in the circumferential direction. The second protrusion 47 is connected to the flange 45.

[0037] The second protrusion 47 extends to the middle portion of the flange 45 in the extending direction. Therefore, the amount by which the second protrusion 47 protrudes from the cylindrical portion 42 is less than the amount by which the first protrusion 46 protrudes from the cylindrical portion 42.

[0038] The second protrusion 47 extends to the edge of the opening 43 in the axial direction of the cylindrical portion 42, i.e., the Z-axis direction. Therefore, the length of the second protrusion 47 in the Z-axis direction is the same as the length of the cylindrical portion 42 in the Z-axis direction from the flange 45 to the edge of the opening 43. The second protrusion 47 is connected to the cylindrical portion 42 throughout the entire Z-axis direction.

[0039] (Structure of shielding shell 50) like Figure 1 and Figure 2 As shown, the shielding shell 50 has: a mounting portion 51 that covers a portion of the retaining portion 41 and is fitted with a shielding member (not shown); a surrounding portion 52 that surrounds the outer periphery of the cylindrical portion 42; and two fixing portions 55 that are fixed to the housing 100. The mounting portion 51, the surrounding portion 52, and the fixing portions 55 are integrated. The shielding shell 50 is formed, for example, by a metal material such as aluminum alloy.

[0040] The assembly part 51 covers the part of the retaining part 41 on the side opposite to the housing 100 in the Z-axis direction and the two sides in the X-axis direction. The surrounding portion 52 extends in the X-axis direction. The surrounding portion 52 has an opening 53 for the insertion of the cylindrical portion 42. The opening 53 is an elongated oval shape that extends in the X-axis direction. The opening 53 is larger than the outer diameter of the cylindrical portion 42.

[0041] The surrounding portion 52 has a peripheral wall 52a that surrounds the outer periphery of the cylindrical portion 42 and the flange 45, and a top wall 52b that extends inward from the peripheral wall 52a throughout the entire periphery of the peripheral wall 52a. like Figure 4 As shown, the top wall 52b surrounds the outer periphery of the portion of the cylindrical portion 42 that is opposite to the insertion portion 44, separated by the flange 45. The top wall 52b covers the outer edge 45a of the flange 45 from the side opposite to the housing 100 in the Z-axis direction. That is, when viewed from the Z-axis direction, the top wall 52b and the flange 45 overlap.

[0042] like Figure 1 and Figure 2 As shown, the surrounding portion 52 has three recesses 54 that engage with the protruding end of the first protrusion 46. Each recess 54 is provided in the top wall 52b at a portion opposite to the first protrusion 46 in the protruding direction. The recess 54 is recessed in the protruding direction of the first protrusion 46 to a peripheral side beyond the outer edge 45a of the flange 45. Furthermore, a gap is provided between the top wall 52b and the second protrusion 47.

[0043] The operation of engaging the recess 54 with the first protrusion 46 can be performed on the housing 40 after the terminal 20 and the counterpart terminal 110 are connected, or on the housing 40 before the terminal 20 and the counterpart terminal 110 are connected.

[0044] like Figure 3 As shown, with the shielding shell 50 fixed to the housing 100, the top wall 52b of the surrounding part 52 is flush with the first protrusion 46. like Figure 1 As shown, the fixing part 55 is provided on both sides of the surrounding part 52 in the X-axis direction. The fixing part 55 protrudes from the top wall 52b in the X-axis direction. The fixing part 55 has a through hole 56 for inserting a bolt 130. By screwing the bolt 130 inserted into the through hole 56 into the threaded hole 102 provided in the housing 100, the shielding shell 50 is fixed to the housing 100.

[0045] The function of this embodiment will be explained. The shielding shell 50 is positioned on the housing 40 by engaging with the recess 54 of the shielding shell 50 and the first protrusion 46 of the housing 40. Thus, the fixing part 55 of the shielding shell 50 is positioned on the machine housing 100.

[0046] The effects of this implementation method will be explained. (1) The connector 10 includes: a plurality of terminals 20 arranged side by side; a resin housing 40 holding the plurality of terminals 20; and a metal shielding shell 50 covering the housing 40 and fixed to the machine housing 100. The housing 40 has: a cylindrical portion 42 having an opening 43 exposing the plurality of terminals 20; and a first protrusion 46 protruding from the cylindrical portion 42 toward the outer periphery of the cylindrical portion 42. The shielding shell 50 has: a surrounding portion 52 surrounding the outer periphery of the cylindrical portion 42; a recess 54 provided in the surrounding portion 52 opposite to the first protrusion 46 and engaging with the first protrusion 46; and a fixing portion 55 having a through hole 56 for inserting a bolt 130 and fixed to the housing 100.

[0047] With this structure, the operation of fixing the shielding shell 50 to the housing 100 by inserting the bolt 130 into the through hole 56 of the fixing part 55 becomes easier because it achieves the aforementioned function. Therefore, the workability reduction during the assembly of the shielding shell 50 can be suppressed.

[0048] (2) The housing 40 has a second protrusion 47, which protrudes from the cylindrical portion 42 toward the outer periphery of the cylindrical portion 42 and extends in the Z-axis direction. With this structure, the rigidity of the cylindrical portion 42 is increased because the second protrusion 47 extends in the Z-axis direction. As a result, for example, the occurrence of forming defects such as shrinkage marks in the shell 40 can be suppressed, thus improving the dimensional accuracy of the opening 43 of the cylindrical portion 42.

[0049] (3) The surrounding portion 52 extends in the X-axis direction. The fixing portion 55 is provided on both sides of the surrounding portion 52 in the X-axis direction. With this structure, the fixing parts 55 are provided on both sides in the X-axis direction surrounding the part 52. Therefore, the shielding shell 50 is fixed to the housing 100 on both sides in the direction extending around the part 52. As a result, the distance between the fixing parts 55 can be easily ensured. Therefore, the shielding shell 50 can be stably fixed to the housing 100.

[0050] (4) The housing 40 has a flange 45 extending from the cylindrical portion 42 toward the surrounding portion 52. The top wall 52b of the surrounding portion 52 covers the flange 45 in the Z-axis direction from the side opposite to the housing 100.

[0051] With this structure, the flange 45 is covered in the Z-axis direction from the side opposite to the housing 100 by the top wall 52b of the surrounding part 52. This makes it easy to position the shielding shell 50 onto the housing 40 in the Z-axis direction. Therefore, it further reduces the decrease in workability during the assembly of the shielding shell 50.

[0052] (5) The first protrusion 46 is connected to the flange 45 and extends to the outer edge 45a of the flange 45. With this structure, the strength of the flange 45 can be increased by utilizing the first protrusion 46.

[0053] <Variation Example> This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other within the scope of technical inconsistency.

[0054] • The first protrusion 46 may also not be connected to the flange 45. In this case, a gap is created between the first protrusion 46 and the flange 45 in the Z-axis direction. • The first protrusion 46 may not extend to the outer edge 45a of the flange 45. That is, the first protrusion 46 may extend to the middle portion in the extending direction of the flange 45. In this case, the flange 45 protrudes outward from the peripheral side beyond the first protrusion 46. Even with such a structure, the strength of the flange 45 can be increased by utilizing the first protrusion 46.

[0055] • The first protrusion 46 may also extend outward from the outer edge 45a of the flange 45. Even with this structure, the top wall 52b of the surrounding portion 52 covers the flange 45 in the Z-axis direction, thus preventing the cylindrical portion 42 inserted into the opening 53 of the surrounding portion 52 from disengaging from the surrounding portion 52. Therefore, this operation can be performed appropriately, especially in the operation of pre-assembling the shielding shell 50 for the housing 40 before assembly to the housing 100.

[0056] • The top wall 52b can be omitted from the surrounding portion 52. That is, the surrounding portion 52 may not cover the flange 45 in the Z-axis direction. • The flange 45 can be omitted from the housing 40.

[0057] The shielding shell 50 may have one fixing part 55 or more than three fixing parts 55. • The positions of each fixing part 55 can be appropriately changed. For example, the fixing part 55 may protrude only in the X-axis direction or in the Y-axis direction.

[0058] • The number of the second protrusion 47 can be appropriately changed. The second protrusion 47 may also protrude until it contacts the top wall 52b of the surrounding portion 52. In this case, in addition to the first protrusion 46, the second protrusion 47 can also be used to position the shielding shell 50 and the housing 40.

[0059] • The second protrusion 47 may not extend to the edge of the opening 43 in the Z-axis direction. That is, the length of the second protrusion 47 in the Z-axis direction may be less than the length of the cylindrical portion 42 from the flange 45 to the edge of the opening 43 in the Z-axis direction.

[0060] • The second protrusion 47 can be omitted from the shell 40. • The length of the first protrusion 46 in the Z-axis direction can also be the same as the length of the second protrusion 47 in the Z-axis direction. In this case, the first protrusion 46 protrudes from the top wall 52b of the surrounding portion 52.

[0061] • The number of the first protrusion 46 can be appropriately changed. • The opening 53 can be omitted from the shielding shell 50. In this case, the shielding shell 50 covers the opening 43 of the shell 40.

[0062] The connector 10 disclosed herein can also be applied, for example, to a connector having a male terminal that is inserted into a female terminal provided on a machine. ·like Figure 4 As shown, it is also possible that when the shielding shell 50 is assembled in the housing 100, the flange 45 and the top wall 52b of the surrounding part 52 do not directly contact each other.

[0063] • With the shielding shell 50 assembled in the housing 100, the first protrusion 46 and the recess 54 should overlap at least partially in the Z-axis direction. • The opening 43 of the cylindrical portion 42 in the embodiment is sometimes referred to as the service port, which is used to access the connection portion between the terminal 20 and the counterpart terminal 110. The second protrusion 47 in the embodiment is sometimes referred to as a reinforcing plate, which strengthens the cylindrical portion 42 in a way that reduces deformation of the opening 43, particularly the opening edge of the cylindrical portion 42. For example... Figure 1 , 3As shown in example 4, the second protrusion 47 in this embodiment can also extend from the flange 45 to the opening edge of the cylindrical portion 42. The second protrusion 47 in this embodiment helps to reduce the variation of the extension angle of the cylindrical portion 42 relative to the flange 45 from a predetermined angle that can be a right angle.

[0064] The combination of the first protrusion 46 of the housing 40 and the recess 54 of the shielding shell 50 in the embodiment is sometimes referred to as a positioning mating pair, which is used to position the housing 40 on the shielding shell 50. The first protrusion 46 in the embodiment is sometimes referred to as a positioning plate. The recess 54 in the embodiment is sometimes referred to as a positioning slit.
