Technical Field
[0001] This disclosure relates to connectors for high voltage applications. Background Technology
[0002] In high-voltage connectors used in hybrid vehicles, electric vehicles, etc., high-voltage connectors with cylindrical terminals embedded in the flat counterparty terminals are widely used in order to achieve a stable connection with the flat counterparty terminals formed by busbars or the like. For example, Patent Document 1 shows a high-voltage connector with cylindrical female terminals that connect to the flat machine-side terminals that serve as counterparty terminals.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2014-86152 Summary of the Invention
[0006] The problem that the invention aims to solve
[0007] However, because the machines connected by high-voltage connectors are relatively large, deviations in the position of the counterpart terminal can sometimes occur due to tolerances on the machine side, making it difficult to connect the high-voltage connector to the counterpart terminal. Therefore, the high-voltage connector described in Patent Document 1 employs a structure in which a flexible conductor is used to connect the female terminal to the wire, and the female terminal is held in the connector housing in a way that allows it to shift. Thus, even if a deviation occurs in the position of the counterpart terminal, the deformation of the flexible conductor can shift the position of the female terminal, thereby ensuring reliable contact between the counterpart terminal and the female terminal.
[0008] However, in high-voltage connectors with cylindrical female terminals, such as those in Patent Document 1, a simplified shape is desired to achieve lower costs. Additionally, reducing the storage space of the terminals is also required to meet miniaturization requirements. Furthermore, simplifying the structure by crimping the cylindrical female terminal to a flexible conductor made of a braided conductive wire is technically significant for reducing the number of components and facilitating manufacturing. Additionally, suppressing the increased resistance at the connection between the female terminal and the flexible conductor is also required to improve conductivity and suppress heat generation.
[0009] Therefore, a novel high-voltage connector is disclosed: it achieves stable connection with the other terminal through a simple structure with few components, and also achieves improved conductivity and reduced heat generation.
[0010] Solution for solving the problem
[0011] The high-voltage connector disclosed herein includes: a terminal part having a flat terminal body portion that overlaps with a flat mating terminal in the thickness direction; and an elastic contact portion integrally disposed with the terminal body portion, at least a portion of which is inclined toward the overlapping side that overlaps with the mating terminal. The terminal part has a fixing portion that is fixed to a connector housing having a terminal insertion hole through which the terminal body portion is inserted. The fixing portion is provided with a compression rib that protrudes from one of the opposing inner surfaces of the terminal insertion hole toward the other. The terminal body portion is positioned between the compression rib and the other opposing inner surface.
[0012] Furthermore, the high-voltage connector disclosed herein includes: a terminal part having a flat terminal body portion that overlaps with a flat mating terminal in the thickness direction; and a resilient contact portion integrally disposed with the terminal body portion, at least a portion of which is inclined toward the overlapping side that overlaps with the mating terminal. The terminal part has a fixing portion that is fixed to a connector housing having a terminal insertion hole through which the terminal body portion is inserted. The terminal part is housed in the connector housing such that the thickness direction of the terminal body portion is the vertical direction of the terminal insertion hole. The terminal insertion hole has a flat rectangle and has a pair of partition plates located at the center in the vertical direction and protruding inward from both sides. The space above the pair of partition plates portion forms a mating terminal insertion portion, and the space below the pair of partition plates portion forms a terminal body portion housing portion. Between the opposing surfaces of the pair of partition plates portion, the resilient contact portion is protrudingly disposed so as to be able to contact the mating terminal.

[0038] <Description of embodiments of this disclosure>
[0039] First, embodiments of this disclosure will be described and illustrated.
[0040] The high-voltage connector disclosed herein
[0041] (1) Includes: a terminal part having a flat terminal body portion that overlaps with a flat counterpart terminal in the thickness direction; and an elastic contact portion integrally disposed with the terminal body portion, at least a portion of which is inclined toward the overlapping side that overlaps with the counterpart terminal, the terminal part having a fixing portion fixed to a connector housing having a terminal insertion hole through which the terminal body portion is inserted, and having a compression rib protruding from one of the opposing inner surfaces of the terminal insertion hole toward the other, the terminal body portion being positioned between the compression rib and the other opposing inner surface.
[0042] In addition, the high-voltage connector disclosed herein,
[0043] (2) Includes: a terminal part having a flat terminal body portion that overlaps with a flat counterpart terminal in the thickness direction; and an elastic contact portion integrally disposed with the terminal body portion, at least a portion of which is inclined toward the overlapping side that overlaps with the counterpart terminal. The terminal part has a fixing portion that is fixed to a connector housing having a terminal insertion hole through which the terminal body portion is inserted. The terminal part is housed in the connector housing such that the thickness direction of the terminal body portion is the vertical direction of the terminal insertion hole. The terminal insertion hole has a flat rectangle and has a pair of partition plates that are located in the center of the vertical direction and protrude inward from both sides. The empty space above the pair of partition plates is formed as a counterpart terminal insertion portion, and the empty space below the pair of partition plates is formed as a terminal body portion housing portion. Between the opposing surfaces of the pair of partition plates, the elastic contact portion is arranged to protrude in a manner that allows it to contact the counterpart terminal.
[0044] According to the high-voltage connector disclosed herein, by forming the terminal body portion constituting the terminal component into a flat plate shape, the shape is simplified compared to conventional cylindrical female terminals used for connecting to flat female terminals, thus achieving cost reduction. Furthermore, the storage space required to house the terminal body portion can be reduced, enabling miniaturization of the high-voltage connector.
[0045] When the terminal body portion connected to the flat counterpart terminal is flat, poor contact between the terminal body portion and the counterpart terminal can easily occur. However, in the high-voltage connector of this disclosure, a resilient contact portion provided on the terminal body portion can maintain stable contact with the counterpart terminal. That is, the resilient contact portion has a portion that is inclined in the direction of the thickness of the terminal body portion toward the counterpart terminal, and this inclined portion can elastically deform in the direction of the thickness of the terminal body portion by changing the inclination angle. Therefore, by pressing the resilient contact portion against the counterpart terminal, the positional deviation of the counterpart terminal is absorbed by the elastic deformation of the resilient contact portion, and a stable contact state between the counterpart terminal and the resilient contact portion can be achieved.
[0046] Because the flexible contact portion and the terminal component are integrally formed, as described above, poor contact can be avoided through a simple structure with fewer components. Furthermore, since the flexible contact portion is an integral structure, localized increases in resistance at the connection point, such as when connecting two different components, are less likely to occur, resulting in excellent conductivity and suppressing heat generation during energization.
[0047] Furthermore, by fixing the terminal parts to the connector housing, vibration of the terminal body is reduced, and miniaturization is achieved by reducing the storage space required to house the terminal body.
[0048] In the high-voltage connector described in (1) above, the pressing ribs protruding from the opposing inner surfaces of the terminal insertion holes are appropriately pressed by the terminal body, thereby allowing for dimensional tolerances in the terminal insertion holes. Because the pressing ribs are provided protruding from either side of the opposing inner surfaces of the terminal insertion holes towards the other side, the terminal body is stably positioned by being pressed against the other opposing inner surface of the terminal insertion holes by the pressing ribs. By clamping and holding the terminal body between the pressing ribs and the other opposing inner surface of the terminal insertion holes, vibrations of the terminal body can be suppressed, and for example, the storage space of the terminal body can be reduced.
[0049] In the high-voltage connector described in (2) above, the terminal parts can be housed in the connector housing such that the vertical direction of the terminal insertion hole of the connector housing is the same as the thickness direction of the terminal body. Therefore, compared with the case where the vertical direction of the terminal insertion hole of the connector housing is the same as the width direction of the terminal body, it is advantageous to achieve a thinner connector housing.
[0050] In addition, by setting a simple structure with a pair of partition plates protruding inward from both sides of the terminal insertion hole, the main body of the terminal can be stored in a space-saving manner and kept in a state that can be connected to the other terminal.
[0051] (3) In (2) above, preferably, the terminal body portion of the terminal component extends along the axial direction of the terminal body portion receiving portion, and the fixing portion of the terminal component extends downward in the vertical direction from the base end of the terminal body portion, having a pressing rib provided on the lower surface of the pair of partition plates and protruding towards the lower inner surface of the terminal body portion receiving portion, the pressing rib pressing the top end portion of the terminal body portion towards the lower inner surface. The terminal component has a terminal body portion and a fixing portion extending downward from the base end of the terminal body portion, and has an L-shape. When the fixing portion is fixed to the connector housing, the top end portion of the terminal body portion of the L-shaped terminal component, located on the side opposite to the fixing portion, may float upward due to the fixing force of the fixing portion and the connector housing. However, by using the pressing rib provided on the upper inner surface of the terminal insertion hole, the top end portion of the terminal body portion can be pressed towards the lower inner surface. Therefore, the floating of the terminal body can be prevented, and the L-shaped terminal part can be stably positioned and held in the expected position relative to the connector housing through the cooperation of the fixing part and the pressing rib.
[0052] (4) Preferably, the resilient contact portion is provided on the terminal body by cutting and erecting it. By cutting and erecting a portion of the terminal body, the resilient contact portion can be easily provided integrally with the terminal body. In addition, it is also easy to provide an inclined portion on the resilient contact portion such that at least a portion of the resilient contact portion protrudes toward the other terminal side.
[0053] (5) In (4) above, preferably, the terminal body has a frame-shaped portion forming the outer peripheral end and an elastic contact portion disposed on the inner peripheral side of the frame-shaped portion through a slit. The elastic contact portion is a leaf spring-like structure that is integrally connected to the frame-shaped portion at its base end and is cut and erected in a cantilever beam shape toward the overlapping side that overlaps with the counterpart terminal, allowing it to elastically deform in the thickness direction. This allows for the provision of an elastic contact portion that is erected by cutting, with good yield and durability.
[0054] (6) In either (4) or (5) above, it is preferable that the elastic contact portion is provided with a first inclined portion that is inclined toward the top of the terminal body portion toward the overlapping side that overlaps with the other terminal, and a second inclined portion is provided in the elastic contact portion on the side closer to the top of the first inclined portion that is inclined toward the top of the terminal body portion toward the side opposite to the overlapping side that overlaps with the other terminal.
[0055] Accordingly, based on the elasticity of the first inclined portion, the elastic contact portion remains in contact with the counterpart terminal. Furthermore, by providing a second inclined portion closer to the tip than the first inclined portion, when the counterpart terminal is inserted from the tip side, the tip of the counterpart terminal contacts the second inclined portion. Thus, the counterpart terminal is guided along the second inclined portion without hooking, allowing it to be inserted into the appropriate position.
[0056] (7) In any of (1) to (3) above, it is preferable that the resilient contact portion is provided by folding back the top end of the terminal body portion. By folding back the top end of the terminal body portion, the resilient contact portion can be easily provided integrally with the terminal body portion. In addition, it is also easy to provide an inclined portion of the resilient contact portion such that at least a portion of the resilient contact portion protrudes towards the other terminal. Furthermore, by folding back the top end of the terminal body portion to form a curved shape, when the other terminal is inserted from the top end and overlaps with the resilient contact portion, the other terminal is less likely to hook onto the top end of the terminal body portion.
[0057] (8) In (7) above, preferably, the terminal body portion has a flat plate portion, a bent folded portion provided at the top of the flat plate portion, and an elastic contact portion extending from the folded portion toward the base end side. The elastic contact portion is integrally connected to the folded portion and is in the form of a leaf spring, inclined in a cantilever beam shape toward the overlapping side that overlaps with the opposite terminal, and capable of elastic deformation in the thickness direction. Thus, the elastic contact portion provided by the folded portion can be provided with good manufacturability.
[0058] (9) In either (7) or (8) above, it is preferable that the elastic contact portion is provided with a third inclined portion, the third inclined portion being inclined toward the base end of the terminal body portion which is the side opposite to the folded-back side of the elastic contact portion toward the overlapping side that overlaps with the other terminal, and the elastic contact portion having a fourth inclined portion on the side of the terminal body portion closer to the base end of the terminal body portion than the third inclined portion, which is inclined toward the base end of the terminal body portion toward the side opposite to the overlapping side that overlaps with the other terminal.
[0059] Accordingly, the portion of the resilient contact portion that protrudes towards the overlapping side of the counterpart terminal is formed by a third inclined portion, maintaining the resilient contact portion in contact with the counterpart terminal. Furthermore, through the third inclined portion, when the counterpart terminal is inserted from the top side and overlaps with the resilient contact portion, the top of the counterpart terminal is guided to contact the third inclined portion, preventing the counterpart terminal from being hooked and smoothly inserted into the appropriate position. Moreover, because the fourth inclined portion is inclined towards the base end of the terminal body portion, approaching the terminal body portion, when the resilient contact portion elastically deforms, the fourth inclined portion abuts against the opposing terminal body portion, thereby limiting the amount of deformation of the folded-back portion, or in other words, the change in the angle of the third inclined portion. Therefore, excessive deformation of the folded-back portion can be prevented, avoiding damage such as plastic deformation of the folded-back portion. Furthermore, in the contact state between the resilient contact portion and the counterpart terminal, the end of the terminal body portion in the resilient contact portion, located at the base end, is positioned away from the counterpart terminal by the fourth inclined portion, preventing damage to the counterpart terminal caused by edge contact of the base end of the terminal body portion in the resilient contact portion.
[0060] (10) Preferably, the end of the wire is connected to the terminal part at the fixing part, and a fixing member is provided to fix the fixing part, the connector housing, and the end of the wire together. By setting the fixing position of the terminal part and the connector housing to be approximately the same as the fixing position of the terminal part and the wire, for example, when the input from the wire side is transmitted to the connector housing via the terminal part, the torque acting on the terminal part by the input is reduced. Therefore, it is easy to prevent vibration, misalignment, etc. of the terminal body in the terminal part.
[0061] (11) Preferably, the terminal part is connected to the end of the wire without the aid of a component capable of elastic deformation. This is because: by providing an elastic contact part in the terminal body, even if a component capable of elastic deformation, such as a braid, is not located between the terminal part and the end of the wire, a stable contact state between the terminal body and the other terminal can be achieved with a simple structure having a small number of parts.
[0062] (12) Preferably, the terminal body is surrounded by a shielding member. In high-voltage connectors, this enables miniaturization, stable connection with the other side connector, and further prevention of noise leakage.
[0063] <Details of the embodiments of this disclosure>
[0064] The following is a reference to the appendix. Figure 1 Specific examples of high-voltage connectors for this disclosure are described below. Furthermore, this disclosure is not limited to these examples, but is intended to include all modifications within the meaning and scope of the claims, as shown by the claims.
[0065] <Implementation Method 1>
[0066] The following is a reference. Figures 1 to 11 The following describes Embodiment 1 of this disclosure. The high-voltage connector 10, for example, is a high-voltage connector located on the machine side that connects to a counterpart connector 74 (described later) located on the power supply side in a high-voltage wiring (not shown) that supplies power from a battery or other power source to a machine such as an inverter or motor. Furthermore, the orientation of the high-voltage connector 10 when mounted in a vehicle is not limited; in the following description, "upward" will be referred to as... Figure 1 In the Z direction, the so-called forward direction is set as Figure 1 In the X direction, the so-called left side is set as Figure 1 The Y direction is explained in the figure. In addition, for multiple identical components, sometimes only some are labeled with reference numerals, while the reference numerals for other components are omitted.
[0067] <High Voltage Connector 10>
[0068] like Figures 1-4 As shown, the high-voltage connector 10 has a structure in which a pair of terminal parts 16, 16 are assembled on a connector housing 14 for mounting to a machine such as an inverter. Furthermore, for ease of viewing and understanding, in Figure 1 , 2 The rear of the box 12 is shown omitted. Figure 3 , 4 The illustration of the middle box 12 is omitted.
[0069] <Connector Housing 14>
[0070] The connector housing 14 is constructed, for example, by an inner member made of an electrically insulating synthetic resin or the like and an outer metal member embedded within the inner member. The connector housing 14 is generally formed as a bottomed, rounded-corner rectangular tube with an opening facing forward. The connector housing 14 has a flange-shaped mounting piece 18 extending outwards at its rear end. Bolt holes 20 are formed through the four corners of the mounting piece 18. A cylindrical shielding member 22 made of a conductive material such as metal is inserted into the inner periphery of the connector housing 14. Figure 5 As shown, a pair of terminal insertion holes 26, 26 extending through the front and rear directions are provided on the bottom surface 24 of the connector housing 14.
[0071] like Figure 1 As shown, the rear surface of the connector housing 14 overlaps with the housing 12, and the connector housing 14 is fixed to the housing 12 by bolts 28 inserted into bolt holes 20. Figure 3 , 4 As shown, an annular sealing rubber 30 is disposed between the rear surface of the connector housing 14 and the housing 12, and the overlapping surfaces of the connector housing 14 and the housing 12 are liquid-tightly sealed by the sealing rubber 30.
[0072] <Compression Rib 32>
[0073] like Figure 5 , 6 As shown, each terminal insertion hole 26 has a pressing rib 32a protruding from one of its opposing inner surfaces 31, 31, facing each other in the left-right direction, and a pressing rib 32b protruding from one of its opposing inner surfaces 33, 33, facing each other in the up-down direction. The pressing ribs 32 protrude in the left-right or up-down direction, forming a head-narrow shape that narrows towards the protruding tip. The pressing ribs 32a protruding in the left-right direction of the terminal insertion hole 26 are respectively provided at both ends of the terminal insertion hole 26 in the up-down direction.
[0074] <Terminal Component 16>
[0075] Terminal component 16 is formed of a conductive metallic material. For example... Figures 7-10As shown, the terminal part 16 includes a terminal body portion 34 formed in the shape of a flat plate. The terminal body portion 34 has a frame-shaped portion 36 forming the outer peripheral end and an elastic contact portion 38 provided with a slit 37 between the frame-shaped portion 36 and the inner peripheral side of the frame-shaped portion 36. The elastic contact portion 38 is formed by partially cutting and erecting the metal plate constituting the terminal body portion 34, and is integrally continuous with the frame-shaped portion 36 at the base end. The elastic contact portion 38 is formed into a leaf spring shape that can elastically deform in the plate thickness direction by being cut and erected at an angle in the overlapping side that overlaps with the counterpart terminal 76 described later, in the overlapping direction. Through elastic deformation, it is allowed to tilt relative to the frame-shaped portion 36 in the plate thickness direction. The slit 37 formed between the frame-shaped portion 36 and the elastic contact portion 38 extends in a way that surrounds the front side and the upper and lower sides of the elastic contact portion 38 in three directions. As a result, the elastic contact portion 38 provided by cutting and erecting can be provided with good yield and durability.
[0076] At least a portion of the resilient contact portion 38 extends from the base end, i.e., the rear end, connected to the frame-shaped portion 36. Figure 10 The left end of the middle) faces the tip, which is the free end formed by passing through the slit 37, i.e., the front end ( Figure 10 (right end of the middle), in the left and right directions that represent the plate thickness direction ( Figure 9 The elastic contact portion 38 is inclined outward in the left-right direction relative to the frame portion 36, thus becoming the overlapping side of the opposite terminal 76 described later.
[0077] The top 40 of the resilient contact portion 38, where the protrusion from the frame-shaped portion 36 in the plate thickness direction becomes the largest, is located midway from the rear end toward the front end. The resilient contact portion 38 has a first inclined portion 42 that slopes in the plate thickness direction toward the overlapping side that overlaps with the counterpart terminal 76, and the amount of protrusion of the resilient contact portion 38 from the frame-shaped portion 36 in the plate thickness direction gradually increases from the rear end toward the top 40. Additionally, the resilient contact portion 38 has a second inclined portion 44 that slopes in the direction opposite to the overlapping side that overlaps with the counterpart terminal 76 from the top 40 toward the front end, and the amount of protrusion of the resilient contact portion 38 from the frame-shaped portion 36 in the plate thickness direction gradually decreases from the top 40 toward the front end. The top 40 of the resilient contact portion 38 is formed in a convex shape in a dotted manner, and the top 40 protrudes more significantly relative to the frame-shaped portion 36.
[0078] The frame-shaped portion 36 has a groove 46. The groove 46 is provided by opening on the upper or lower surface of the frame-shaped portion 36 and extends through the frame-shaped portion 36 in the left-right direction. The inner surface of the front side wall of the groove 46 is formed into a return structure that slopes forward as it leaves the opening in the up-down direction. The inner surface of the front side wall of the groove 46 may also be formed into a stepped shape, for example, in such a way that the portion closer to the opening is narrower than the portion farther from the opening.
[0079] A fixing part 48 and a wire connecting part 50 are provided on the rear side of the terminal body 34. The fixing part 48 is continuously provided with the rear end of the terminal body 34 and extends orthogonally to the terminal body 34, and has a bolt hole 52 that passes through in the front-rear direction. The wire connecting part 50 is continuously provided with the rear end of the fixing part 48 and extends orthogonally to both the terminal body 34 and the fixing part 48, and has a bolt hole 54 that passes through in the vertical direction.
[0080] Furthermore, the pair of terminal parts 16, 16 are symmetrical in the left-right direction, so by... Figures 7-10 The description focuses on one terminal part 16, thus omitting the description of the other terminal part 16. Furthermore, the groove 46 of one terminal part 16 is provided with an opening on the upper surface of the frame-like portion 36, and the groove 46 of the other terminal part 16 is provided with an opening on the lower surface of the frame-like portion 36. Therefore, it can be understood that the so-called pair of terminal parts 16, 16 are not strictly limited to mathematically symmetrical shapes; even if there are slight differences, they can still be considered symmetrical shapes.
[0081] like Figure 2 As shown, the terminal part 16 is fixed to the connector housing 14 by means of a fixing part 48 overlapping the rear surface of the connector housing 14 and a bolt 56 inserted into the bolt hole 52. Thus, by fixing the rear part of the terminal part 16 to the connector housing 14, the terminal body 34 is positioned within the connector housing 14, suppressing displacement such as vibration of the terminal body 34. Therefore, the surrounding space considering vibration of the terminal body 34 can be significantly narrowed compared to female terminals supported by conventional braids, enabling miniaturization of the high-voltage connector 10. Furthermore, the method of fixing the fixing part 48 to the connector housing 14 is not particularly limited.
[0082] The terminal body 34 of the terminal component 16 is inserted into the terminal insertion hole 26 provided in the connector housing 14, and the terminal body 34 protrudes forward from the inner periphery of the connector housing 14. Figure 5 , 6 As shown, a pressing rib 32, which protrudes from one opposing inner surface 31 of the terminal insertion hole 26 in a left-right direction, presses against the rear end portion of the terminal body portion 34 that is inserted into the terminal insertion hole 26. Thus, the rear end portion of the terminal body portion 34 is positioned between the pressing rib 32 and the other opposing inner surface 31 in the left-right direction. Furthermore, a pressing rib 32, which protrudes from one opposing inner surface 33 of the terminal insertion hole 26 in a vertical direction, presses against the rear end portion of the terminal body portion 34 that is inserted into the terminal insertion hole 26. Thus, the rear end portion of the terminal body portion 34 is positioned between the pressing rib 32 and the other opposing inner surface 33 in the vertical direction.
[0083] When the terminal body 34 is inserted into the terminal insertion hole 26, the compression rib 32 appropriately compresses it, thereby allowing for deviations in the position of the bolt 56 on the fastening part of the terminal part 16 and the terminal insertion hole 26, making it easy to assemble the terminal part 16 into the connector housing 14. In addition, the terminal body 34 is positioned further forward relative to the connector housing 14 in the left-right and up-down directions, further suppressing displacement of the terminal body 34, thus achieving space-saving storage and stabilizing the connection state with the other terminal 76.
[0084] The terminal body portion 34, which protrudes into the inner periphery of the connector housing 14, is surrounded by a shielding member 22 that covers the inner peripheral surface of the connector housing 14. Therefore, in the high-voltage connector 10 constituting high-voltage wiring, noise leakage can be prevented, and effects on surrounding circuits, for example, can be prevented.
[0085] <Anti-electric shock cover 58>
[0086] An anti-electric shock cover 58 is installed on the terminal body portion 34 protruding into the inner peripheral space of the connector housing 14. The anti-electric shock cover 58 is formed of an electrically insulating synthetic resin or the like and is installed on the top portion of the terminal body portion 34, forming a structure that covers the top surface and both vertically and horizontally sides of the terminal body portion 34. The anti-electric shock cover 58 is formed as an integral structure where the portions of a pair of terminal bodies 34, 34 are connected to each other, and can be installed together with terminal parts 16, 16. By configuring the anti-electric shock cover 58 to cover the front of the opposing space between the terminal bodies 34, 34, it prevents fingers and tools from being inserted into the opposing space between the terminal bodies 34, 34. Furthermore, the anti-electric shock cover 58 has a portion that covers the front of the opposing space between the terminal bodies 34, 34 and the connector housing 14, thus also preventing fingers and tools from being inserted into the opposing space between the terminal bodies 34, 34 and the connector housing 14. In addition, in Figure 3 For ease of viewing, the illustration of the anti-electric shock cover 58 is omitted.
[0087] <Wire 60>
[0088] like Figure 2As shown, a wire 60 is connected to the wire connection portion 50 of the terminal part 16. The wire 60 is an insulated wire with a conductive metal core surrounded by an electrically insulating synthetic resin or the like. A crimp terminal 62 is fixed to the end of the core exposed from the insulating cover of the wire 60 in a conductive state by means of tightening or the like. The crimp terminal 62 has a flat cylindrical wire fixing portion 64 and a plate-shaped connecting portion 66 protruding from the wire fixing portion 64, and a bolt hole 68 extending through in the thickness direction is formed in the plate-shaped connecting portion 66. The crimp terminal 62 is fixed to the wire connection portion 50 of the terminal part 16 by bolts 70 and nuts 72 inserted into the bolt holes 54 and 68. Thus, the wire 60 is connected to the terminal part 16 in a conductive state. The terminal part 16 is connected to the end of the wire 60 without the aid of a component that can elastically deform, such as a braid, and is fixedly positioned.
[0089] <Contact 74 on the opposite side>
[0090] The counterpart connector 74 has a pair of counterpart terminals 76, 76 (see reference). Figure 11 The opposite terminals 76 and 76 are flat and are arranged in a left-right direction, spaced apart from the terminal bodies 34 and 34.
[0091] <Connection between high-voltage connector 10 and the opposite connector 74>
[0092] like Figure 11 As shown, the high-voltage connector 10 is connected to the counterpart connector 74 by embedding the counterpart connector 74 into the inner circumference of the connector housing 14. The high-voltage connector 10 and the counterpart connector 74 are fixedly positioned relative to each other in the connected state. Furthermore, in the connected state, the terminal bodies 34, 34 of the high-voltage connector 10 and the counterpart terminals 76, 76 overlap each other in the thickness direction in a contact state. Additionally, in... Figure 11 In the diagram, for ease of viewing, the structures of the high-voltage connector 10 and the opposite connector 74 are shown schematically in a simplified manner.
[0093] That is, the elastic contact portion 38 of the terminal body portion 34 protrudes outward relative to the frame portion 36 in the left-right direction as the plate thickness direction, and the top 40 of the elastic contact portion 38 contacts the counterpart terminal 76, which overlaps with the outer surface of the terminal body portion 34 in the left-right direction. As a result, the elastic contact portion 38 of the terminal body portion 34 is pressed in by the counterpart terminal 76, elastically deforming in a manner that reduces the tilt angle relative to the frame portion 36. The degree of tilt of the elastic contact portion 38 relative to the frame portion 36 varies depending on the relative position of the terminal body portion 34 and the counterpart terminal 76 in the left-right direction. Therefore, even if there is an error in the relative position of the terminal body portion 34 and the counterpart terminal 76 in the left-right direction, a stable contact state between the terminal body portion 34 and the counterpart terminal 76 can be achieved by elastically pressing the elastic contact portion 38 of the terminal body portion 34 against the counterpart terminal 76. Furthermore, in Figure 11 In the middle, the elastic contact portion 38 of the terminal body portion 34, which is not in contact with the other terminal 76, is shown in a single state using a double-dotted line.
[0094] Thus, because the terminal body 34 is provided with an elastic contact portion 38 that allows for elastic deformation and displacement, a stable contact state between the terminal body 34 and the counterpart terminal 76 can be achieved with a simple structure having a small number of components. Furthermore, the elastic contact portion 38, which allows for elastic deformation and displacement, is integrally formed with the frame portion 36 by being cut upright, preventing any increase in resistance between the elastic contact portion 38 and the frame portion 36 due to the connection of the two components. Therefore, excellent conductivity can be achieved, and heat generation due to energization can also be reduced.
[0095] Furthermore, by providing the elastic contact portion 38 in the terminal body portion 34, the terminal body portion 34, which connects to the flat-shaped counterpart terminal 76, is not cylindrical like conventional female terminals, but rather flat. This simplifies the structure of the terminal body portion 34, enabling cost reduction of the terminal component 16, ease of manufacturing, and miniaturization of the high-voltage connector 10 by narrowing the storage space of the terminal component 16.
[0096] By providing the first inclined portion 42, the top 40 of the elastic contact portion 38 protrudes towards the opposite terminal 76 in the thickness direction compared to the frame portion 36. The opposite terminal 76 contacts the terminal body portion 34 at the elastic contact portion 38, thus stably achieving a connection between the opposite terminal 76 and the terminal body portion 34. Furthermore, by providing the second inclined portion 44 at the front of the elastic contact portion 38, when the opposite terminal 76 is inserted from the front to the rear of the terminal body portion 34, the opposite terminal 76 is guided along the surface of the second inclined portion 44. Therefore, the opposite terminal 76 is less likely to get stuck on the elastic contact portion 38, and the high-voltage connector 10 and the opposite-side connector 74 can be smoothly connected, with the opposite terminal 76 inserted into the appropriate connection position relative to the terminal body portion 34.
[0097] Because the elastic contact portion 38 of the terminal body 34 elastically contacts and conducts electricity relative to the counterpart terminal 76, it is not necessary to place an elastically deformable component such as a braid between the terminal part 16 and the wire 60 to allow displacement of the terminal part 16 relative to the wire 60. Therefore, a simple structure with fewer components can accommodate tolerances in the relative positions of the terminal body 34 and the counterpart terminal 76, and a stable connection between the terminal body 34 and the counterpart terminal 76 can be achieved with a simple structure.
[0098] <Implementation Method 2>
[0099] Figure 12 , Figure 13 Embodiment 2 of this disclosure is shown. The high-voltage connector 80 includes a pair of terminal parts 82, 82. In the following description, components and parts that are substantially the same as those in Embodiment 1 are labeled with the same reference numerals in the figures and are omitted from the description.
[0100] Terminal part 82, unlike terminal part 16 in Embodiment 1, is structured without the wire connection portion 50, and is composed of terminal body portion 34 and fixing portion 48. The fixing portion 48 of terminal part 82 overlaps with the rear surface of connector housing 14, and the plate-shaped connecting portion 66 of crimp terminal 62, provided at the end of wire 60, overlaps with the rear surface of fixing portion 48. Furthermore, bolts 56, serving as fixing members, are inserted into bolt holes 52 of terminal part 82 and bolt holes 68 of crimp terminal 62, and bolts 56 are screwed into nut portion 84 of connector housing 14. Thus, terminal part 82 and crimp terminal 62 fixed to wire 60 are fixed together in approximately the same position relative to connector housing 14. The fixing portion 48 of terminal part 82 and the plate-shaped connecting portion 66 of crimp terminal 62, fixed to connector housing 14 by bolts 56, overlap and contact each other, and terminal part 82 and wire 60 are electrically connected. Furthermore, the crimp terminal 62 can also be arranged between the connector housing 14 and the fixing portion 48 of the terminal part 82, in other words, in a manner that overlaps with the front surface of the fixing portion 48. The fixing member that fixes the terminal part 82 and the crimp terminal 62 provided on the wire 60 to the connector housing 14 is not limited to the bolt 56, but can also be made of, for example, a pin, a brazing alloy, etc.
[0101] According to this embodiment 2, since the wire 60 and the terminal part 82 are fixed together to the connector housing 14, the input from the wire 60 side to the terminal part 82 side is directly transmitted to the connector housing 14 and is received, and is not easily transmitted to the terminal body portion 34 of the terminal part 82. Furthermore, compared with the case where the fixed position of the terminal part 82 to the connector housing 14 is different from the fixed position of the wire 60 to the terminal part 82, the torque based on the input from the wire 60 is less likely to act on the terminal part 82, so vibration and misalignment of the terminal part 82 can be prevented.
[0102] <Implementation Method 3>
[0103] Figure 14 Embodiment 3 of this disclosure is shown. The high-voltage connector 90 includes a pair of terminal parts 92, 92. Furthermore, the pair of terminal parts 92, 92 are formed in a mutually symmetrical shape, so as in Embodiment 1, only one terminal part 92 will be described.
[0104] Terminal component 92 is formed of a conductive metallic material. For example... Figure 15 , Figure 16 As shown, the terminal part 92 includes a plate-shaped terminal body portion 94. A fixing portion 48 and a wire connection portion 50 are integrally provided on the base end side (rear side) of the terminal body portion 94. The terminal body portion 94 has a flat plate portion 96 extending forward from the fixing portion 48, and an elastic contact portion 98 extending from the top end of the flat plate portion 96. The flat plate portion 96 has a vertical direction ( Figure 15 The width dimension (in the Z direction and the opposite direction) changes in two stages, with the top side being narrower than the base side. Furthermore, the terminal part 92 can be obtained, for example, by stamping a sheet of conductive metal.
[0105] The resilient contact portion 98 is provided with a folded-back portion 100 that bends at the top of the flat plate portion 96, which serves as the top of the terminal body portion 94. This folded-back portion 100 is formed by the terminal body portion 94 folding back and extending towards the base end. Therefore, the terminal body portion 94 has a dual structure in which the resilient contact portion 98 and the flat plate portion 96 are separated and opposite each other in the thickness direction at their top portions. The resilient contact portion 98 is opposite the flat plate portion 96 in its top portion, which has a smaller width dimension in the vertical direction, and does not reach the base end portion, which has a larger width dimension in the vertical direction.
[0106] The base end of the resilient contact portion 98 is integrally connected to the folded-back portion 100, and the top end portion of the resilient contact portion 98 is formed as a third inclined portion 102. The third inclined portion 102 extends toward the base end of the terminal body portion 94 as a terminal to the other terminal 76 (see reference). Figure 16 The outer side of the overlapping side in the left and right directions ( Figure 15 The elastic contact portion 98 is inclined in the direction opposite to the Y direction. That is, the elastic contact portion 98 is inclined in a cantilever beam shape towards the overlapping side that overlaps with the opposite terminal 76, and is in the shape of a leaf spring that can elastically deform in the thickness direction of the plate. As a result, the elastic contact portion 98 provided by the folding-back arrangement can be provided with good manufacturability. As the top end portion of the elastic contact portion 98, which is composed of the third inclined portion 102, moves away from the folding-back portion 100 towards the base end side, the distance between the opposing portions of the flat plate portion 96 increases, and it protrudes more outward in the left and right directions towards the base end side.
[0107] The end portion of the terminal body portion 94 in the elastic contact portion 98 is formed as a fourth inclined portion 104 at the base end. The fourth inclined portion 104 extends inward in the left-right direction toward the base end of the terminal body portion 94, opposite to the overlapping side of the opposite terminal 76. Figure 15The fourth inclined portion 104 is inclined in the Y direction. The end portion of the terminal body portion 94 in the elastic contact portion 98, which is composed of the fourth inclined portion 104, approaches the flat plate portion 96 towards the base end of the terminal body portion 94. The distance between the opposing fourth inclined portion 104 and the flat plate portion 96 becomes minimal at the end portion of the terminal body portion 94 in the fourth inclined portion 104 at the base end. Therefore, the elastic contact portion 98 is composed of consecutive third inclined portions 102 and fourth inclined portions 104, and the amount of outward protrusion in the left-right direction at the boundary between the end portion of the terminal body portion 94 in the third inclined portion 102 and the end portion of the terminal body portion 94 in the fourth inclined portion 104 becomes maximum. The length of the fourth inclined portion 104 is shorter than the length of the third inclined portion 102, which can suppress deflection caused by bending in the thickness direction. Furthermore, Figure 16 The counterpart terminal 76 is virtually shown with a double-dotted line. Similar to Embodiment 1, the counterpart terminal 76 is inserted by pressing the elastic contact portion 98 inward in the left-right direction from the top side of the terminal body portion 94, and overlaps with the elastic contact portion 98 in a contact state.
[0108] The distance between the fourth inclined portion 104 and the flat portion 96 in the left-right direction is set according to the allowable angle change of the third inclined portion 102 when the elastic contact portion 98 and the counterpart terminal 76 are in contact. That is, when the elastic contact portion 98 is pressed inward in the left-right direction by the counterpart terminal 76, the base end of the fourth inclined portion 104 contacts the flat portion 96, thereby limiting the amount of displacement of the elastic contact portion 98 in the left-right inward direction and limiting the angle change of the third inclined portion 102. In addition, the base end of the fourth inclined portion 104 can be separated from or connected to the flat portion 96 when the elastic contact portion 98 is not in contact with the counterpart terminal 76.
[0109] However, the fourth inclined portion 104 is not necessary; for example, the entire elastic contact portion may be constructed using the third inclined portion 102. Alternatively, a portion substantially parallel to the flat plate portion 96 may be provided on the base end side of the terminal body portion 94 in the third inclined portion 102 to increase the contact area between the elastic contact portion and the counterpart terminal 76.
[0110] According to the high-voltage connector 90 equipped with terminal parts 92, 92 configured in this embodiment, a stable contact state with the other terminal 76 can be obtained by utilizing the elastic contact part 98 with a simple structure formed by folding back.
[0111] Furthermore, by providing a bent, folded-back portion 100 at the top of the terminal body portion 94, when the other terminal 76 is inserted from the top side relative to the terminal body portion 94, the other terminal 76 is less likely to get stuck at the top of the terminal body portion 94 and is smoothly guided towards the overlapping side that overlaps with the elastic contact portion 98. Moreover, the top of the elastic contact portion 98, which is continuous with the folded-back portion 100, is formed as a third inclined portion 102, and the width dimension of the terminal body portion 94 in the left-right direction decreases towards the top of the portion where the elastic contact portion 98 is formed. As a result, it is possible to prevent the other terminal 76 from getting stuck when inserted from the top side, and a stable contact state with the other terminal 76 can be achieved.
[0112] The resilient contact portion 98 is inclined toward the overlapping side of the third inclined portion 102 toward the base end of the terminal body portion 94, and protrudes toward the opposite terminal 76. Therefore, when the opposite terminal 76 is inserted from the top end side of the terminal body portion 94 and overlaps with it, the resilient contact portion 98 protruding toward the opposite terminal 76 makes stable contact with the opposite terminal 76.
[0113] Furthermore, by having the base end of the terminal body portion 94 in the fourth inclined portion 104 contact the flat plate portion 96, the amount of approach displacement of the elastic contact portion 98 toward the flat plate portion 96, which occurs with the change in the tilt angle of the third inclined portion 102, is limited. Therefore, excessive deformation of the folded-back portion 100 and plastic deformation of the folded-back portion 100 can be prevented. As a result, even if, for example, the high-voltage connector 90 and the counterpart connector (not shown) are repeatedly connected and disconnected, the contact state between the elastic contact portion 98 of the terminal body portion 94 and the counterpart terminal 76 remains stable.
[0114] Furthermore, the edge of the base end of the terminal body portion 94 in the elastic contact portion 98 is moved away from the contact position with the counterpart terminal 76 in the overlapping direction due to the fourth inclined portion 104. As a result, damage such as scratches to the counterpart terminal 76 caused by contact of the edge of the base end of the terminal body portion 94 in the elastic contact portion 98 can be avoided.
[0115] <Implementation Method 4>
[0116] Figure 17 Embodiment 4 of this disclosure is shown. The high-voltage connector 110 includes a pair of terminal parts 112, 112.
[0117] Terminal part 112, unlike terminal part 92 in Embodiment 3, is structured without the wire connection portion 50, and is composed of terminal body portion 94 and fixing portion 48. The fixing portion 48 of terminal part 112 overlaps with the rear surface of connector housing 14, and the plate-shaped connecting portion 66 of crimp terminal 62 provided at the end of wire 60 overlaps with the rear surface of fixing portion 48. Furthermore, bolts 56, serving as fixing members, are inserted into bolt holes 52 of terminal part 112 and bolt holes 68 of crimp terminal 62, and bolts 56 are screwed into nut portion 84 of connector housing 14. Thus, terminal part 112 and crimp terminal 62 fixed to wire 60 are fixed together in approximately the same position relative to connector housing 14. The fixing portion 48 of terminal part 112 and the plate-shaped connecting portion 66 of crimp terminal 62, fixed to connector housing 14 by bolts 56, contact and overlap each other, and terminal part 112 and wire 60 are electrically connected. In addition, the crimp terminal 62 can also be configured such that it is located between the connector housing 14 and the fixing part 48 of the terminal part 112, in other words, it can be configured to overlap with the front surface of the fixing part 48.
[0118] According to this embodiment 4, the input from the wire 60 side to the terminal part 112 side is directly transmitted to the connector housing 14 and is received, and is not easily transmitted to the terminal body 94 of the terminal part 112. In addition, since the torque from the input from the wire 60 is not easily applied to the terminal part 112, vibration and misalignment of the terminal part 112 can be prevented.
[0119] <Implementation Method 5>
[0120] Figures 18-23 Embodiment 5 of this disclosure is shown. The high-voltage connector 114 has a structure in which a pair of terminal parts 118, 118 are assembled in a connector housing 116 fixed to a machine (not shown). In the following description, components and parts that are substantially the same as those in Embodiment 1 are labeled with the same reference numerals in the figures and are omitted from the description.
[0121] <Connector Housing 116>
[0122] The connector housing 116 is formed, for example, of an electrically insulating synthetic resin. The connector housing 116 is formed into a rectangular cylindrical shape, bent into an L-shape and opening towards the front and bottom. A flat partition 124 is provided in the front cylindrical portion 120 of the connector housing 116, which extends in the front-rear direction (opposite to the X direction) and divides the interior of the front cylindrical portion 120 in the left-right direction (Y direction and opposite to Y direction) to form a pair of flat rectangular terminal insertion holes 122, 122. Each terminal insertion hole 122 has a pair of partition plates 126, 126, located in the central portion in the vertical direction and protruding inward from both sides. The space above the pair of partition plates 126, 126 forms a counterpart terminal insertion portion 128 for inserting the counterpart terminal 76, and the space below the pair of partition plates 126, 126 forms a terminal body storage portion 130 for storing the terminal body portion 34. For example… Figure 20 As shown, between the opposing surfaces of a pair of partition plates 126, 126, the resilient contact portion 38 is protruding in a manner that allows it to contact the opposite terminal 76. Additionally, for example... Figure 21 As shown, each of the pair of partition plates 126 has a head-shaped pressing rib 132 provided on its lower surface. The pressing rib 132 protrudes toward the lower inner surface of the terminal body receiving portion 130 and extends from the front end toward the rear.
[0123] A cutout 138 is formed on the rear wall 136 of the rear cylindrical portion 134 of the connector housing 116, which opens downwards, covering the entire surface except for the lower end. A nut portion 84 (see reference) is provided on the rear surface of the front wall 140 of the rear cylindrical portion 134 of the connector housing 116, which opens rearwards in the central portion for engaging a bolt 142. Figure 22 Furthermore, for ease of understanding, bolt 142 is shown with an imaginary line.
[0124] <Terminal Parts 118>
[0125] like Figure 23 As shown, the terminal part 118, compared to the terminal part 16 of Embodiment 1, is structured without the wire connection portion 50, and is constituted by the terminal body portion 34 and the fixing portion 48. Figure 22As shown, the fixing portion 48 of the terminal part 118 extends downward in the vertical direction from the base end of the terminal body portion 34 and overlaps with the rear surface of the front wall portion 140 of the connector housing 116. Furthermore, the plate-shaped connecting portion 66 of the crimp terminal 62 provided at the end of the wire 60 overlaps with the rear surface of the fixing portion 48. A bolt 142, serving as a fixing member, is inserted into the bolt hole 52 of the terminal part 118 and the bolt hole 68 of the crimp terminal 62, and the bolt 142 is screwed into the nut portion 84 of the connector housing 116. Thus, the terminal part 118 and the crimp terminal 62 fixed to the wire 60 are fixed together in approximately the same position relative to the connector housing 116. The fixing portion 48 of the terminal part 118 and the plate-shaped connecting portion 66 of the crimp terminal 62, which are bolted to the connector housing 116, contact and overlap each other, and the terminal part 118 and the wire 60 are electrically connected.
[0126] Thus, the terminal body portion 34 of the terminal part 118 extends along the axial direction (X direction) of the terminal body portion receiving portion 130, and the terminal part 118 is housed in the connector housing 116 such that the thickness direction of the terminal body portion 34 is aligned with the vertical direction of the terminal insertion hole 122. In addition, the pressing rib 132 presses the top end of the terminal body portion 34 toward the lower inner surface of the terminal body portion receiving portion 130.
[0127] According to this embodiment 5, the terminal component 118 is housed in the connector housing 116 such that the thickness direction of the terminal body 34 aligns with the vertical direction of the terminal insertion hole 122. Therefore, compared to the case where the vertical direction of the terminal insertion hole 122 of the connector housing 116 aligns with the width direction of the terminal body 34, a thinner connector housing 116 can be advantageously achieved. Furthermore, by providing a simple structure with a pair of partition plates 126, 126 protruding inward from both sides of the terminal insertion hole 122, the terminal body 34 and the counterpart connector 74 can be space-savingly housed and maintained in a connectable state. Moreover, since the high-voltage connector 114 has a pair of terminal components 118, 118, it can advantageously engage and connect with a counterpart terminal having terminals arranged side-by-side at a certain distance in the width direction.
[0128] Furthermore, according to this embodiment, the top end of the terminal body portion 34, which is provided on the side opposite to the fixing portion 48 of the L-shaped terminal part 118, may float upwards due to the fixing portion 48 and the connector housing 116. However, by using the pressing rib 132 provided on the lower surface of the partition plate portion 126 of the terminal insertion hole 122 of the connector housing 116, the top end of the terminal body portion 34 can be pressed towards the lower inner surface. Therefore, the floating of the top end of the terminal body portion 34 can be prevented, thereby stably positioning and holding the L-shaped terminal part 118 relative to the connector housing 116 in the desired position.
[0129] <Other Implementation Methods>
[0130] The technology described in this specification is not limited to the embodiments described above and the accompanying drawings. For example, the following embodiments are also included in the technical scope of the technology described in this specification.
[0131] (1) In Embodiment 1, a high-voltage connector 10 having a pair of terminal parts 16, 16 is shown. However, in a high-voltage connector, the number of terminal parts can be one or more than three. In addition, when a pair or more than three terminal parts are provided, the shape, size, etc. of those terminal parts can be different from each other. For example, the terminal part 16 of Embodiment 1 and the terminal part 92 of Embodiment 3 can also be used in combination.
[0132] (2) In Embodiment 1, the elastic contact portion 38 is formed by cutting and erecting it with the rear end of the terminal body portion 34 as the base. However, for example, the elastic contact portion 38 can also be formed by cutting and erecting it with the front end of the terminal body portion 34 as the base. In short, the free end of the elastic contact portion 38 can be located on either the top end side or the base end side of the terminal body portion 34. When it is located on the base end side of the terminal body portion 34, it is easier to avoid hooking or jamming caused by collision with the other terminal 76.
[0133] (3) The elastic contact portion 38 may not necessarily be provided in the middle part of the terminal body portion. For example, it may be provided at the end in the width direction of the terminal body portion (the vertical direction of embodiments 1 to 4 and the horizontal direction of embodiment 5).
[0134] (4) Multiple resilient contact portions 38 may also be provided on a single terminal body portion 34. In this case, the shapes, sizes, etc. of the multiple resilient contact portions 38 may also be different from each other.
[0135] (5) The elastic contact portion 38 does not need to be tilted as a whole relative to the frame portion 36. For example, it may have a portion that extends approximately parallel to the frame portion 36.
[0136] (6) In Embodiment 1, the high-voltage connector 10 and the counterpart connector 74 are connected, so that the counterpart terminals 76, 76 overlap with the outer surfaces of the terminal bodies 34, 34 in the left-right direction. However, for example, the counterpart terminals 76, 76 may be inserted between the opposing terminals 34, 34 in the left-right direction, and the counterpart terminals 76, 76 overlap with the inner surfaces of the terminal bodies 34, 34. In this case, the elastic contact portion 38 of Embodiment 1 is cut and erected relative to the frame portion 36 in a manner that protrudes inward in a direction opposite to that of Embodiment 1 in the plate thickness direction. In short, the inclined portion of the elastic contact portion is inclined in a manner that protrudes towards the overlapping side of the counterpart terminal 76.
[0137] (7) In embodiment 1, the high voltage connector 10 and the counterpart connector 74 are inserted into the inner periphery of the high voltage connector 10 and connected thereto. However, for example, the high voltage connector 10 may also be inserted into the inner periphery of the counterpart connector 74 and connected thereto.
[0138] (8) In embodiment 5, similar to embodiment 1, a compression rib 32 may be provided on the base end side of the terminal body receiving portion 130. As a result, the terminal body portion 34 is more stably received and held within the terminal body receiving portion 130.
