Description

Technical field

[0001] One technique revealed by this description relates to a connector. State of the art

[0002] A connector arrangement described in Japanese patent publication JP 2017-134969A is known, for example, as a conventional connector. This connector comprises a housing with a working cylindrical section formed into an elliptical shape slightly elongated in a forward-backward direction, and a terminal that is partially embedded in the housing by insertion or forming. The terminal includes a projecting section extending forward from an inner wall of the working cylindrical section, a coupling section extending downward from the front end of the projecting section, and a connecting section extending forward from a lower end portion of the coupling section.The connecting section is designed with an insertion hole that passes through in a vertical direction, and a bolt is or will be inserted into this insertion hole.

[0003] Furthermore, publication JP 2005 - 261 017 A discloses a busbar housing with a first busbar that is rigidly fixed, and a second busbar and a third busbar that are slidably attached to a first cover and a second cover.

[0004] US 2014 / 0015313A1 describes a power control unit (PCU) mounted on a hybrid vehicle that controls the electrical power used to propel the vehicle. The PCU comprises a housing with a top cover featuring an opening, a terminal block located within the housing opposite the opening, and a substrate within the housing on which an electronic component is mounted. The terminal block includes a wall. This wall is located between the substrate and the opening and extends toward the cover around the circumference of the opening. This configuration provides a power control unit that prevents the ingress of foreign objects while reducing size and cost. Summary of the invention: Technical problem

[0005] When the bolt is inserted into the insertion hole of the connecting section of the fitting and secured on a mating or aligned side, a stress is generated at an interface between the protruding section of the fitting and the inner wall of the working cylindrical section, and a load is applied to the inner wall of the working cylindrical section. In particular, if the fitting is a high-flow fitting, the plate thickness of the fitting is greater than that of general fittings. Thus, the stress applied to the interface between the protruding section of the fitting and the inner wall of the working cylindrical section increases further. Solution to the problem

[0006] A connector disclosed in this description is provided with a housing made of a resin or plastic, the housing comprising an opening open in a first direction, and a terminal made of a conductive metal, the terminal being partially embedded in the housing, the terminal comprising a base end section projecting from a first inner wall in the opening of the housing in a second direction towards a second inner wall facing the first inner wall, a connecting section extending in the second direction, the connecting section being connectable to a matching device, and a coupling section.The coupling section includes an end part of the base end section in the second direction and an end part of the connecting section in a direction opposite to the second direction, the base end section and the connecting section are arranged on different axes when viewed or considered in a third direction orthogonally to the first and second directions, and an entire length of the base end section is equal to or longer than a length in the first direction between the base end section and the connecting section.

[0007] The connecting or joining section is slightly displaced or shifted in a fixing direction when it is fixed and connected to the mating or matched device, for example, by a bolt or screw. The base end section is also displaced in the fixing direction over the coupling or joining section, thereby applying a stress or load to a boundary or intermediate surface between the base end section and the inner wall of the housing. At this time, since the total length of the base end section is equal to or greater than the length in the first direction between the base end section and the connecting section, there is a degree of displacement or shift of the base end section on the inner wall side.The side of the inner wall of the housing is smaller than that of the connecting section compared to the case where the entire length of the base end section is shorter than the length in the first direction between the base end section and the connecting section. In this way, the stress applied to the intermediate surface between the base end section and the inner wall of the housing is reduced. Furthermore, since the base end section is more easily deflected and the stress applied to the connecting section is distributed throughout the entire base end section due to its longer overall length, the stress applied to the intermediate surface between the base end section and the inner wall of the housing is reduced. Additionally, since the base end section and the connecting section are on different axes when viewed in the third direction, the stress on the intermediate surface between the base end section and the inner wall of the housing is reduced.Considering that the components are arranged and coupled by the coupling section, the connection as a whole has a cranked or cranked shape. In this way, any stress applied to the connecting section is distributed across both the base end section and the coupling section. This reduces the stress exerted on the intermediate surface or interface between the base end section and the inner wall of the housing. By forming the connection in such a cranked shape, the stress exerted on the intermediate surface between the base end section and the inner wall of the housing can be reduced within a limited space in the housing opening.

[0008] Furthermore, the base end section and the connecting section can be arranged on different or different axes when viewed in the first direction.

[0009] Since the base end section and the connecting section are arranged on different axes when viewed in the first direction, the length of the connecting section is greater compared to a configuration in which the base end section and the connecting section are arranged on the same axis when viewed in the first direction. In this way, the extent of any displacement of the base end section on the inner wall of the housing is smaller than that of the connecting section, and the stress exerted on the intermediate surface between the base end section and the inner wall of the housing is reduced.

[0010] Furthermore, the connecting section can be plate-like and a connecting hole, which is to be connected to the matching device, can be provided in order to be open in a plate surface of the connecting section.

[0011] By providing or supplying the connecting hole in the connecting section, the connection to the matching or coordinated device can be secured by a bolt.

[0012] Furthermore, the connecting hole of the connecting section can be located closer to the second inner wall than to the first inner wall.

[0013] Since the connecting hole is positioned closer to the second inner wall than to the first inner wall, its location is further from the intermediate surface between the base end section and the inner wall of the housing when viewed from above. Consequently, the path along the connection from the connecting hole to this intermediate surface is longer compared to a configuration where the connecting hole is located near the first inner wall. This reduces the displacement of the base end section on the inner wall side of the housing compared to that of the connecting section, thus minimizing the stress exerted on the intermediate surface between the base end section and the inner wall. Effect of the invention

[0014] According to the connector disclosed in this description, it is possible to reduce the stress exerted or applied to the intermediate surface between the inner wall of the housing and the base end section of the connector. Brief description of the drawing Fig. 1 is a top view of a connector in one embodiment, Fig. Figure 2 is a front view of the connector. Fig. 3 is a section along AA in Fig. 1, and Fig. 4 is a section along BB in Fig. 1. embodiment of the invention<Ausführungsform>

[0015] One embodiment is described with reference to Fig. 1 to 4 described. A connector 10 of this embodiment is a connector which is to be connected to an inverter (hereinafter referred to as a “matching or matched device”) of a vehicle, and includes, as described in Fig. Figure 1 shows a mounting plate 12, which is to be mounted on one side of the vehicle, three terminals 14, which are made of a conductive metal and are to be connected to the matching device, and a housing 16, which is made of a resin or plastic and is integrally or integrally molded onto the mounting plate 12 and the terminals 14. In the following description, an upward direction (first direction), a forward direction (second direction), and a rightward direction (third direction) are based on directions which are in Fig. 1 to 4 are shown.

[0016] As this is in Fig. As shown in Figure 3, the housing 16 includes a tubular body section 18, a pair of protective walls 20, and wire-formed sections 22. As shown in Figure 3, the housing 16 comprises a tubular body section 18, a pair of protective walls 20, and wire-formed sections 22. Fig. As shown in Figure 1, three wire forming or casting sections 22 are provided. The body section 18 is provided with a first opening (opening) 24, which is open upwards, and the first opening 24 is designed to have an opening in the form of a long or oblong hole, which is long in a lateral direction in a top view, as shown in Figure 1. Fig. Figure 1 shows. Furthermore, a plate-like bottom wall 28 is provided in a bottom part of the body section 18, and a second opening 30 is provided to be open in the bottom wall 28.

[0017] As this is in Fig. As shown in Figure 2, the pair of protective walls 20 are plate-like and each is designed to project downwards from both left and right edges of the second opening 30. As shown in Fig. As shown in Figure 3, the protective walls 20 are positioned at locations that overlap parts of the connections 14 (parts of coupling sections 38 and connecting sections 36, which will be described later) that are exposed downwards from the second opening 30 of the body section 18 when viewed from the right. This prevents a sheet or plate of the vehicle from laterally contacting the connections 14 when the connector 10 is installed.

[0018] The three wire-formed sections 22 have a cylindrical shape, which is long in the forward-backward direction, and are each designed to project backward from the rear surface of the outer circumference of the body section 18, as shown in Fig. 1 and Fig. Figure 2 shows that the three wire forming sections 22 are arranged at predetermined intervals or distances in the lateral direction.

[0019] The mounting plate 12 is in the form of a plate made of metal, and a mounting plate-side opening 32 is provided to be open in a plate surface of the mounting plate 12, as shown in Fig. Figure 3 shows the opening edge of the opening 32 on the mounting plate side of the mounting plate 12. The opening edge is embedded in the body section 18, whereby the body section 18 is fixed to the mounting plate 12.

[0020] As this is in Fig. As shown in Figure 3, the connection 14 includes a plate-like base end section 34, which projects from an inner wall 26A on one side of a rear surface of the body section 18 in a direction towards an inner wall 26B on one side of a front surface, which is directed towards the inner wall 26A on the side of the rear surface (i.e. forward), the plate-like connecting or connecting section 36, which is long in the forward-backward direction and is to be connected to the mating device, and the plate-like coupling or coupling section 38, which couples a front end part of the base end section 34 and a rear end part of the connecting section 36.

[0021] As this is in Fig. As shown in Figure 1, the three terminals 14 are arranged at predetermined intervals in the lateral direction. Although not shown, a portion of the terminal 14 behind the base end section 34 serves as a wire-connecting section, and this wire-connecting section is embedded in the body section 18. A core of a wire 42, extending in the forward-backward direction, is electrically connected to each of the wire-connecting sections of the three terminals 14. The front ends of the three wires 42 are each embedded in the three wire-forming sections 22, thus holding the three wires 42 in the housing 16.

[0022] As this is in Fig. As shown in Figure 3, an axis S1 of the base end section 34 of the connector 14 and an axis S2 of the connecting section 36 are arranged on different axes. When viewed from the right, the axis S2 of the connecting section 36 is located below the axis S1 of the base end section 34, and the connector 14 has an overall cranked shape. Furthermore, the front end of the base end section 34 and the rear end of the connecting section 36 are in the same position in the forward-backward direction, and the coupling section 38 is orthogonal to the base end section 34 and the connecting section 36, as shown in Figure 3. Fig. 3 is shown.

[0023] As this is in Fig. As shown in Figure 3, a length (total length) L1 in the forward-backward direction of the base end section 34 is equal to or longer than a vertical length L2 between the base end section 34 and the connecting section 36. In this embodiment, the length L1 is essentially equal to the length L2.

[0024] As this is in Fig. As shown in Figure 1, the axis S1 of the base end section 34 of the connection 14 and the axis S2 of the connecting section 36 are arranged on different axes in a top view. In this way, the coupling section 38 is bent in the lateral direction, as shown in Figure 1. Fig. 4 is shown.

[0025] As this is in Fig. As shown in Figure 1, a connecting hole 40, which is to be connected to the mating device, is provided to be open in the plate surface of the connecting section 36. The connecting hole 40 is located closer to the inner wall 26B on the front surface side than to the inner wall 26A on the rear surface side of the body section 18.

[0026] The functions of this embodiment are described next. When a bolt (not illustrated) is inserted into the connecting hole 40 of the connector 14 to connect the connecting section 36 of the connector 14 to the mating device, the connecting section 36 of the connector 14 is slightly displaced in a fixing direction (vertical direction) of the bolt. In this way, the base end section 34 is also displaced vertically over the coupling section 38. Furthermore, a stress is exerted on an intermediate surface or interface between the base end section 34 and the inner wall 26A of the body section 18 due to the vertical displacement of the base end section 34.At this time, since the length L1 of the base end section 34 is essentially equal to the length L2, the displacement of the base end section 34 on the side of the inner wall 26A is less than that of the connecting section 36 compared to the case where the length L1 of the base end section 34 is shorter than the length L2. In this way, the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A is reduced. Furthermore, since the length L1 of the base end section 34 is essentially equal to the length L2, the base end section 34 is deflected more easily, and the stress exerted on the connecting section 36 is distributed over the entire base end section 34 compared to the case where the length L1 is shorter than the length L2.This reduces the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A.

[0027] Furthermore, since the connection 14 has an overall crank shape and the stress applied to the connecting section 36 is distributed across each of the base end section 34 and the coupling section 38, the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A is reduced. By forming the connection in a crank shape in this way, the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A can be reduced within a confined space in the first opening 24 of the body section 18.

[0028] Furthermore, since the axis S1 of the base end section 34 of the connection 14 and the axis S2 of the connecting section 36 are arranged on different axes in a plan view, as shown in Fig. As shown in Figure 1, the vertical length of the coupling section 38 is longer compared to a configuration in which the axis S1 of the base end section 34 of the connection 14 and the axis S2 of the connecting section 36 are arranged on the same axis in a plan view. In this way, the displacement of the base end section 34 on the side of the inner wall 26A is suppressed, and the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A is reduced.

[0029] Furthermore, since the connecting hole 40 is located closer to the inner wall 26B on the front surface than to the inner wall 26A on the rear surface, the position of the connecting hole 40 is further separated from the intermediate surface between the base end section 34 and the inner wall 26A in a plan view. Consequently, the path along the connection from the connecting hole 40 to the intermediate surface between the base end section 34 and the inner wall 26A on the rear surface is longer compared to a configuration where the connecting hole 40 is located near the inner wall 26A. This suppresses the displacement of the base end section 34 on the inner wall 26A side and reduces the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A.

[0030] As described above, according to this embodiment, the connecting section 36 of the connector 14 is slightly displaced or shifted in the fixing or fastening direction when it is fixed and connected to the mating or matched device, for example by a bolt. The base end section 34 is also displaced or shifted in the fixing direction over the coupling section 38, thereby applying or exerting a stress on the intermediate surface or interface between the base end section 34 and the inner wall 26A on the rear surface (inner wall) side of the housing 16. At this time,Since the length (total length) L1 of the base end section 34 is equal to or longer than the length L2 in the first direction between the base end section 34 and the connecting section 36, the displacement of the base end section 34 on the side of the inner wall 26A on the side of the rear surface (inner wall) of the housing 16 is smaller than that of the connecting section 36 compared to the case where the length (total length) L1 of the base end section 34 is shorter than the length L2 in the first direction between the base end section 34 and the connecting section 36. In this way, the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A on the side of the rear surface (inner wall) of the housing 16 is reduced.Furthermore, because the base end section 34 is more easily deflected and the stress applied to the connecting section 36 is distributed throughout the entire base end section 34 due to its longer length (total length) L1, the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A on the rear surface (inner wall) of the housing 16 is reduced. Additionally, because the base end section 34 and the connecting section 36 are arranged on different axes when viewed from the right and coupled by the coupling section 38, the connection 14 has an overall cranked or cranked shape. In this way, a stress exerted on the connecting section 36 is distributed across both the base end section 34 and the coupling section 38.This reduces the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A on the rear surface (inner wall) side of the housing 16. By forming the connection 14 into a crank shape in this way, the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A on the rear surface (inner wall) side of the housing 16 can be reduced in the confined space of the first opening 24 of the housing 16.

[0031] Furthermore, since the base end section 34 and the connecting section 36 are arranged on different axes when viewed in the first direction, the length of the coupling section 38 is longer compared to a configuration in which the base end section 34 and the connecting section 36 are arranged on the same axis when viewed in the first direction. In this way, the displacement of the base end section 34 on the side of the inner wall 26A on the rear surface (inner wall) of the housing 16 is smaller than that of the connecting section 36, and the stress exerted on the intermediate surface between the base end section 34 and the inner wall 26A on the rear surface (inner wall) of the housing 16 is reduced.

[0032] Furthermore, the connection 14 on the matching device can be fixed or fastened by the bolt by providing or supplying the connecting hole 40 in the connecting section 36.

[0033] Furthermore, since the connecting hole 40 is located closer to the inner wall (second inner wall) 26B on the front surface than to the inner wall (first inner wall) 26A on the rear surface, the position of the connecting hole 40 is further or more separated from the intermediate surface between the base end section 34 and the inner wall 26A on the rear surface (inner wall) of the housing 16 in a top view, and the path on the connection 14 from the connecting hole 40 to the intermediate surface between the base end section 34 and the inner wall 26A on the rear surface (inner wall) of the housing 16 is correspondingly longer compared to a configuration in which the connecting hole 40 is located near the inner wall (first inner wall) 26A on the rear surface.In this way, the displacement extent of the base end section 34 on the side of the inner wall 26A of the housing 16 is smaller than that of the connecting section 36, and the stress exerted or applied to the intermediate surface between the base end section 34 and the inner wall 26A on the side of the rear surface (inner wall) of the housing 16 is reduced. <Andere Ausführungsformen>

[0034] The technology disclosed by this description is not limited to the embodiment described and illustrated above. For example, the following different types are also included. (1) Although the length L1 of the base end section 34 is substantially equal to the length L2 in this embodiment, the length L1 may be longer than the length L2. (2) Although the axis S2 of the connecting section 36 is arranged below the axis S1 of the base end section 34 in this embodiment, the axis S2 may be arranged above the axis S1. (3) Although the front end of the base end section 34 and the rear end of the connecting section 36 are located in the same position in the forward-backward direction in this embodiment, these end sections may be located in different positions. For example, a rear end of a connecting section may be located behind a front end of a base end section, and the connection may have an overall Z shape. Furthermore, a rear end of a connecting section may be located in front of a front end of a base end section, and a coupling section may be inclined downwards from the front end of the base end section to the rear end of the connecting section. (4) Although three terminals 14 are provided in this embodiment, two or fewer or four or more terminals may be provided. (5) It should be noted that in this embodiment, the base end section may be a part which, for the sake of simplicity, projects from the first inner wall. Specifically, it is understood that the base end section may be appropriately located in an area where the stress or load exerted on an intermediate surface or interface between the base end section and the inner wall of the housing can be reduced.
