Description

Technical Field

[0001] This disclosure relates to connector assemblies. Background Technology

[0002] Conventionally, vehicles such as hybrid vehicles and electric vehicles include onboard devices such as high-voltage batteries and inverters. These onboard devices are connected to each other via wiring harnesses and connector assemblies. Each connector assembly includes a first connector and a second connector that can connect to the first connector. The first connector has a first housing and a first terminal. The second connector has a second housing that can be fitted with the first housing by relative movement along a first axis, and a second terminal that can connect to the first terminal. As such a first connector, there is a connector with a terminal position guaranteeing member (see, for example, Patent Document 1). The terminal position guaranteeing member can be assembled into a guarantee position within the housing, for example, when the first terminal is in its normal position within the first housing. The first housing has a housing opening that allows the terminal position guaranteeing member to be assembled into the guarantee position from a direction orthogonal to the first axis. The terminal position guaranteeing member maintains the first terminal in its normal position when assembled into the guarantee position through the housing opening.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2002-329548 Summary of the Invention The problem that the invention aims to solve

[0004] However, especially in wiring harnesses connected to high-voltage batteries, electromagnetic shielding components such as braided members are needed to suppress electromagnetic wave radiation. In such cases, electromagnetic wave radiation also needs to be suppressed in connector assemblies. Therefore, for example, it is considered to provide a first electromagnetic shielding component that covers the area around the first terminal in the first housing. However, in the first housing described above, an opening is also required in the first electromagnetic shielding component, corresponding to the housing opening. Therefore, electromagnetic waves may radiate from the opening in the connector assembly.

[0009] [Description of embodiments of this disclosure] First, embodiments of this disclosure will be described. The connector assembly disclosed herein, [1] A first connector and a second connector capable of being connected to the first connector are provided. The first connector has: a first housing; a first terminal held within the first housing; a first electromagnetic shielding member held within the first housing and covering the area around the first terminal; and a terminal position guaranteeing member capable of being assembled into a guaranteed position within the first housing when the first terminal is in its normal position within the first housing. The second connector has: a second housing capable of being connected to the first housing by relative movement along a first axis. The first housing has a housing opening for assembling the terminal position guaranteeing member into the guaranteed position from a direction intersecting the first axis, and a shielding opening for assembling the terminal position guaranteeing member into the guaranteed position from a direction intersecting the first axis, and a closure portion for sealing the shielding opening.

[0010] According to this structure, with the first terminal in its normal position within the first housing, the terminal position guaranteeing member can be assembled to the guaranteeing position via the housing opening and the shielding opening from a direction intersecting the first axis. This ensures the first terminal is in its normal position. Furthermore, electromagnetic wave radiation from the first connector is suppressed by the first electromagnetic shielding member. Electromagnetic wave radiation from the second connector is suppressed by the second electromagnetic shielding member. Moreover, when the second connector is connected to the first connector, the shielding opening of the first electromagnetic shielding member is sealed by the closing portion of the second electromagnetic shielding member, thus also suppressing electromagnetic wave radiation from the shielding opening.

[0011] [2] Preferably, the first housing has: a terminal holding portion for holding the first terminal; and a wall portion disposed on the outside of the terminal holding portion, forming the housing opening portion, wherein the terminal holding portion and the wall portion are integrally formed.

[0012] According to this structure, the terminal holding portion holding the first terminal and the wall portion provided outside the terminal holding portion and forming a housing opening are integrally molded, thus reducing the number of components constituting the first housing. Furthermore, when the terminal holding portion and the wall portion are separate, it is possible to configure the structure so that the housing opening and shielding opening are not provided. For example, the wall portion can be assembled into the terminal holding portion after the terminal position guaranteeing member is assembled into the guaranteeing position. In contrast, in this structure, the terminal holding portion and the wall portion are integrally molded, resulting in a reduction in the number of components and also suppressing electromagnetic wave radiation from the shielding opening.

[0013] [3] Preferably, the wall portion has: a first wall portion having the first electromagnetic shielding member held on the inner side and having a first opening portion as the housing opening portion; and a second wall portion disposed on the outer side of the first wall portion and having a second opening portion as the housing opening portion, the second housing having a sealing wall portion inserted between the first wall portion and the second wall portion to prevent liquid from seeping into the first opening portion from the outside.

[0014] According to this structure, when the second connector is connected to the first connector, the sealing wall portion is inserted between the first wall portion and the second wall portion, thus preventing liquid from seeping into the first opening from the outside. Therefore, water immersion of the first terminal, the first electromagnetic shielding member, etc., can be prevented.

[0015] [4] Preferably, the terminal position guaranteeing member has a locking portion, and the first housing has: a formal locking portion, which locks the terminal position guaranteeing member by engaging with the locking portion when the terminal position guaranteeing member is disposed in the guaranteeing position; and a temporary locking portion, which locks the terminal position guaranteeing member by engaging with the locking portion when the terminal position guaranteeing member is disposed in a temporary locking position before reaching the guaranteeing position, wherein the terminal position guaranteeing member allows the first terminal to be assembled into the first housing when disposed in the temporary locking position.

[0016] According to this structure, when the terminal position guaranteeing member is positioned in the guaranteeing position, it is locked by engaging the locking portion with the permanent locking portion. Therefore, for example, movement of the terminal position guaranteeing member from the guaranteeing position can be prevented before the second housing and the first housing are fitted together. Furthermore, when the terminal position guaranteeing member is positioned in the temporary locking position, it is locked by engaging the locking portion with the temporary locking portion. And, the first terminal is allowed to be assembled into the first housing when the terminal position guaranteeing member is positioned in the temporary locking position. Therefore, for example, it is possible to... Before the first terminal is assembled into the first housing, the terminal position guaranteeing component is held in a temporary locking position. This makes component management of the terminal position guaranteeing component before the first terminal is assembled easier.

[0017] [5] Preferably, the terminal position guaranteeing member prevents the second housing from engaging with the first housing when it is configured in the temporary locking position. According to this structure, when the terminal position guaranteeing member is in a temporary locking position, the second housing is prevented from engaging with the first housing by the terminal position guaranteeing member. Therefore, misassembly of the first and second housings can be prevented before the terminal position guaranteeing member is in the guaranteeing position.

[0018] [6] Preferably, the second housing prevents the terminal position guaranteeing member disposed at the guaranteeing position from moving when it is engaged with the first housing. According to this structure, the terminal position guaranteeing member disposed in the guaranteed position is prevented from moving by the second housing when the second housing and the first housing are engaged. Therefore, when the second housing and the first housing are engaged, the first terminal can be maintained in its normal position within the first housing.

[0019] [Details of the embodiments of this disclosure] Specific examples of the connector assembly 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. Furthermore, the dimensional ratios of the various parts sometimes differ in the drawings. The terms "parallel," "orthogonal," and "circular" in this specification include not only cases where they are strictly parallel, orthogonal, or circular, but also cases where they are generally parallel, orthogonal, or circular to the extent that they achieve the desired effect in this embodiment. Moreover, the invention is not limited to these examples, but is intended, through the claims, to include all variations within the meaning and scope equivalent to the claims.

[0020] [Structure of Connector Assembly 11] like Figure 1 and Figure 2 As shown, connector assembly 11 includes a first connector 21 and a second connector 31. The second connector 31 can be connected to the first connector 21 by moving relative to the first connector 21 in a first direction X1 along the first axis X. Connector assembly 11 is provided in a vehicle. For example, the vehicle includes on-board equipment such as a high-voltage battery and an inverter, which are connected to each other via wire D. Connector assembly 11 is provided, for example, as a component for connecting the on-board equipment and wire D. Furthermore, the figure illustrates the first axis X, the second axis Y orthogonal to the first axis X, and the axis Y perpendicular to the first axis X. The third axis Z is orthogonal to the second axis Y. Additionally, the diagram illustrates the first direction X1 and the first opposite direction X2. The first direction X1 is along the first axis X, and the first opposite direction X2 is along the first axis X and is the opposite of the first direction X1.

[0021] [Structure of Connector 21] like Figures 2-5 As shown, the first connector 21 has a first housing 22 and a first terminal 23 held within the first housing 22. Additionally, as... Figure 2 , Figure 4 and Figure 5 As shown, the first connector 21 has a first electromagnetic shielding member 24 (see reference). Figure 7 The first electromagnetic shielding member 24 is held in the first housing 22 and covers the periphery of the first terminal 23 around the first axis X. In addition, the first connector 21 has a terminal position guarantee member 25, which can be assembled into a guarantee position within the first housing 22 when the first terminal 23 is in its normal position within the first housing 22.

[0022] [Structure of the second connector 31] like Figure 2 and Figure 3 As shown, the second connector 31 has a second housing 32 and a second terminal 33. The second housing 32 can be engaged with the first housing 22 by moving relative to the first housing 22 in a first direction X1 along the first axis X. The second terminal 33 is held within the second housing 32 and can be connected to the first terminal 23. Additionally, as... Figure 2 As shown, the second connector 31 has a second electromagnetic shielding member 34 (see reference). Figure 12 The second electromagnetic shielding member 34 is held in the second housing 32 and covers the area around the second terminal 33 around the first axis X.

[0023] [Structure of the first shell 22] The first housing 22 is made of an insulating resin material. like Figure 3 As shown, the first housing 22 is formed in a square cylindrical shape and opens in the first opposite direction X2. Figure 4 As shown, the first housing 22 has a terminal holding portion 26 for holding the first terminal 23. The terminal holding portion 26 is provided on the first opposite direction X2 side of the first housing 22. The terminal holding portion 26 is formed into a square tube shape that extends along the first axis X. Two terminal holding portions 26 are arranged along the second axis Y.

[0024] Furthermore, the first housing 22 has a first wall portion 27 and a second wall portion 28 serving as wall portions on the outer side of the terminal holding portion 26. The first wall portion 27 covers the periphery of the terminal holding portion 26 around the first axis X. The first wall portion 27 covers both terminal holding portions 26 together. The terminal holding portion 26 is connected to the first wall portion 27 on the first direction X1 side. The second wall portion 28 The first wall portion 27 is covered around the first axis X. The second wall portion 28 is connected to the first wall portion 27 on the first direction X1 side. The terminal holding portion 26, the first wall portion 27 and the second wall portion 28 are integrally molded.

[0025] Additionally, each terminal holding portion 26 has an assembly opening 26a. The assembly opening 26a is provided on the outer wall 26b of the terminal holding portion 26 that intersects the second axis Y. The first wall portion 27 has a first opening 27a that serves as a housing opening. The first opening 27a is provided on two walls 27b of the first wall portion 27 that intersect the second axis Y. The second wall portion 28 has a second opening 28a that serves as a housing opening. The second opening 28a is provided on two walls 28b of the second wall portion 28 that intersect the second axis Y. The assembly openings 26a, the first opening 27a, and the second opening 28a are arranged along the second axis Y. Furthermore, a sealing rubber 29 is provided on the outer peripheral surface of the first wall portion 27 on the first direction X1 side.

[0026] [Structure of Terminal 23] like Figure 5 As shown, the first terminal 23 extends along the first axis X. The first terminal 23 is held inside the terminal holding portion 26. The first terminal 23 is inserted into the terminal holding portion 26 from the first direction X1 side towards the first opposite direction X2. The first terminal 23 has a necked-out portion (middle tapering portion) 23a in the middle portion along the first axis X. Compared with other portions, the width of the necked-out portion 23a in the second axis Y direction is smaller. The first terminal 23 has a female terminal portion 23b on the first opposite direction X2 side. Furthermore, in... Figure 2 , Figures 4-6 The cross-section of the female terminal portion 23b is schematically illustrated. The female terminal portion 23b also has a spear-shaped portion 23c. The spear-shaped portion 23c engages with the terminal holding portion 26 by extending in a manner that extends towards the first direction X1 and expands outward, thereby preventing the first terminal 23 from falling off the terminal holding portion 26. Furthermore, the first terminal 23 has a wire connecting portion 23d in the first direction X1. The wire connecting portion 23d is connected to the core wire D1 of the wire D. In addition, in... Figure 2 , Figures 4-6 The cross-section of wire D is schematically illustrated in the figure.

[0027] [Structure of the first electromagnetic shielding component 24] The first electromagnetic shielding component 24 is made of metal sheet. like Figure 4 and Figure 5 As shown, the first electromagnetic shielding member 24 is held on the inner peripheral surface of the first wall portion 27.

[0028] like Figure 7 As shown, the first electromagnetic shielding member 24 is generally formed in a square cylindrical shape. The first electromagnetic shielding member 24 has a first contact piece 24a and a second contact piece 24b on the first opposite direction X2 side. The first contact piece 24a is disposed in the first electromagnetic shielding member 24 and connects with the first contact piece 24b. Two walls 24c intersecting the third axis Z. A first contact piece 24a has a gap inside the first electromagnetic shielding member 24 and is folded back, allowing it to flex. Three first contact pieces 24a are arranged along the second axis Y. A second contact piece 24b is provided in the first electromagnetic shielding member 24 on two walls 24d intersecting the second axis Y. The second contact piece 24b extends along the first axis X by being punched around its periphery, allowing it to flex. Furthermore, a contact point protruding towards the inside of the first electromagnetic shielding member 24 is formed at the top of the second contact piece 24b. The first electromagnetic shielding member 24 has a shielding opening 24e. The shielding opening 24e is provided in the first electromagnetic shielding member 24 on two walls 24d intersecting the second axis Y. Figure 5 As shown, the shielding opening 24e, assembly opening 26a, first opening 27a, and second opening 28a are arranged along the second axis Y. Furthermore, the wire D has an inner covering, a braided member, and other electromagnetic shielding components, as well as an outer covering, on the outside of the core wire D1. The first electromagnetic shielding component 24 is electrically connected to the electromagnetic shielding component of the wire D in the first direction X1 (illustration omitted).

[0029] [Structure of terminal position guarantee component 25] The terminal position guarantee component 25 is made of resin material. like Figure 3 , Figure 8 and Figure 9 As shown, the terminal position guaranteeing member 25 is formed in a U-shape. The two ends of the U-shape of the terminal position guaranteeing member 25 can bend in a direction separating from each other. The terminal position guaranteeing member 25 has a locking portion 25a. The locking portion 25a decreases in width from both ends of the U-shape and extends further, extending further from its top end towards the opposite side. Additionally, the terminal position guaranteeing member 25 has a protrusion 25b that protrudes inward from the center of the U-shape.

[0030] like Figure 5 , Figure 8 and Figure 9As shown, the terminal position guaranteeing member 25 can be assembled to the terminal holding part 26 from the outside of the first housing 22. In detail, the terminal position guaranteeing member 25 can be assembled to the assembly opening 26a of the terminal holding part 26 from a direction intersecting the first axis X and along the second axis Y through the second opening 28a, the first opening 27a and the shielding opening 24e.

[0031] like Figure 9 As shown, the terminal holding part 26 has a formal locking part 26c. When the terminal position guaranteeing member 25 is positioned in the guaranteeing position, the formal locking part 26c engages with the locking part 25a to lock the terminal position guaranteeing member 25. Additionally, as... Figure 8 As shown, the terminal holding part 26 has a temporary locking part 26d. When the terminal position guaranteeing member 25 is positioned in a temporary locking position before reaching the guarantee position, the temporary locking part 26d engages with the locking part 25a to lock the terminal position guaranteeing member 25.

[0032] When the first terminal 23 is in its normal position within the first housing 22, the terminal position guaranteeing member 25 is inserted into the neck 23a of the first terminal 23 via the protrusion 25b, thereby assembling it into the guaranteed position. That is, as... Figure 5 and Figure 9 As shown, the terminal position guaranteeing member 25 is embedded in the neck 23a in the guaranteed position. Additionally, as... Figure 6 and Figure 8 As shown, when the terminal position securing member 25 is in the temporary locking position, the protrusion 25b does not enter the inside of the terminal holding portion 26, allowing the first terminal 23 to be assembled into the terminal holding portion 26. Furthermore, when the terminal position securing member 25 is in the temporary locking position, it is positioned between the terminal holding portion 26 and the first wall portion 27, thereby preventing the second housing 32 from engaging with the first housing 22.

[0033] In addition, such as Figure 10 and Figure 11 As shown, the locking portion 25a is positioned offset from the center of the terminal position guaranteeing member 25 along the first axis X. This prevents misassembly of the terminal position guaranteeing member 25. Specifically, when the terminal position guaranteeing member 25 is in a reverse orientation along one side and the other side along the third axis Z, the locking portion 25a collides with the engaging portion 26e provided on the terminal holding portion 26, preventing assembly to the terminal holding portion 26.

[0034] [Structure of the second shell 32] The second housing 32 is made of an insulating resin material. like Figure 2As shown, the second housing 32 has a rectangular inner wall portion 35 that can be inserted between the terminal holding portion 26 and the first wall portion 27. The inner wall portion 35 is located between the terminal holding portion 26 and the first wall portion 27 when the second housing 32 and the first housing 22 are engaged. Furthermore, when the second housing 32 and the first housing 22 are engaged, the inner wall portion 35 prevents movement of the terminal position guaranteeing member 25, which covers the assembly opening 26a and is positioned in a guarantee position. Additionally, the second housing 32 has a rectangular sealing wall portion 36 that can be inserted between the first wall portion 27 and the second wall portion 28. The sealing wall portion 36 is located between the first wall portion 27 and the second wall portion 28 when the second housing 32 and the first housing 22 are engaged. Furthermore, when the second housing 32 and the first housing 22 are engaged, the sealing wall portion 36 is in close contact with the sealing rubber 29, preventing liquid from seeping into the first opening 27a from the outside.

[0035] [Structure of Terminal 2 33] like Figure 2 As shown, the second terminal 33 extends along the first axis X. The second terminal 33 has a male terminal portion 33a on the first direction X1 side. The male terminal portion 33a is inserted into and connected to the female terminal portion 23b when the second housing 32 is engaged with the first housing 22.

[0036] [Structure of the second electromagnetic shielding component 34] The second electromagnetic shielding component 34 is made of metal sheet. like Figure 2 As shown, the second electromagnetic shielding member 34 is held on the outer peripheral surface of the inner wall portion 35.

[0037] like Figure 12 As shown, the second electromagnetic shielding member 34 is integrally formed in a square cylindrical shape. The second electromagnetic shielding member 34 has a closed portion 34a. The closed portion 34a is formed by two walls 34b in the second electromagnetic shielding member 34 that intersect the second axis Y. The closed portion 34a seals the shielding opening 24e when the second housing 32 is engaged with the first housing 22. Furthermore, when the second housing 32 is engaged with the first housing 22, the second electromagnetic shielding member 34 is protected by the first contact piece 24a and the second contact piece 24b of the first electromagnetic shielding member 24 (see reference). Figure 7 Press to make contact and electrically connect with the first electromagnetic shielding component 24.

[0038] Next, the function of the connector assembly 11 configured as described above will be explained. For example... Figure 6 As shown, the first terminal 23 is inserted into the terminal holding portion 26 from the first direction X1 side to the first reverse direction X2, thereby assembling it into the first housing 22. Furthermore, when the first terminal 23 is positioned in its normal position within the first housing 22, as... Figure 5As shown, the terminal position securing member 25 is pressed into the securing position by a fixture or the like. Furthermore, as... Figure 2 As shown, when the second housing 32 is fitted with the first housing 22, the first terminal 23 and the second terminal 33 are electrically connected, and the first electromagnetic shielding member 24 and the second electromagnetic shielding member 34 are electrically connected.

[0039] Next, the effects of the above-described embodiments will be described. (1) When the first terminal 23 is in its normal position within the first housing 22, the terminal position guaranteeing member 25 can be assembled to the guaranteeing position from a direction intersecting the first axis X via the first opening 27a, the second opening 28a, and the shielding opening 24e. This ensures that the first terminal 23 is in its normal position. Furthermore, electromagnetic wave radiation from the first connector 21 is suppressed by the first electromagnetic shielding member 24. Electromagnetic wave radiation from the second connector 31 is suppressed by the second electromagnetic shielding member 34. Moreover, when the second connector 31 is connected to the first connector 21, the shielding opening 24e of the first electromagnetic shielding member 24 is sealed by the closing portion 34a of the second electromagnetic shielding member 34, thus also suppressing electromagnetic wave radiation from the shielding opening 24e.

[0040] (2) The terminal holding portion 26, the first wall portion 27, and the second wall portion 28 are integrally molded, thus reducing the number of components constituting the first housing 22. Furthermore, in the terminal holding portion... When the terminal holding portion 26, the first wall portion 27, and the second wall portion 28 are separate components, the first opening portion 27a, the second opening portion 28a, and the shielding opening portion 24e can be omitted. For example, the first wall portion 27 and the second wall portion 28 can be assembled on the terminal holding portion 26 after the terminal position guaranteeing member 25 is assembled into the guaranteeing position. In contrast, in this embodiment, the terminal holding portion 26, the first wall portion 27, and the second wall portion 28 are integrally molded, which reduces the number of parts and also suppresses electromagnetic waves from the shielding opening portion 24e.

[0041] (3) With the second connector 31 connected to the first connector 21, the sealing wall 36 is inserted between the first wall 27 and the second wall 28, thus preventing liquid from entering the first opening 27a from the outside. Therefore, the first terminal 23, the first electromagnetic shielding member 24, etc., can be prevented from being immersed in water.

[0042] (4) When the terminal position guaranteeing member 25 is positioned in the guaranteeing position, it engages with the regular locking part 26c via the locking part 25a, thereby locking with the terminal holding part 26 (see reference). Figure 9Therefore, for example, movement of the terminal position guaranteeing member 25 from the guaranteeing position can be suppressed before the second housing 32 and the first housing 22 are engaged. Furthermore, when the terminal position guaranteeing member 25 is positioned in the temporary locking position, it engages with the temporary locking portion 26d via the locking portion 25a, thereby locking it with the terminal holding portion 26 (see reference). Figure 8 Furthermore, the first terminal 23 is allowed to be assembled into the first housing 22 with the terminal position guaranteeing member 25 in a temporary locking position. Therefore, for example, the terminal position guaranteeing member 25 can be held in a temporary locking position before the first terminal 23 is assembled into the first housing 22. As a result, component management of the terminal position guaranteeing member 25 before the first terminal 23 is assembled becomes easier.

[0043] (5) When the terminal position guarantee member 25 is in the temporary locking position, the second housing 32 is prevented from engaging with the first housing 22 by the terminal position guarantee member 25. Therefore, the first housing 22 and the second housing 32 can be prevented from being misassembled before the terminal position guarantee member 25 is in the guarantee position.

[0044] (6) The terminal position guaranteeing member 25, which is positioned in the guarantee position, is prevented from moving by the second housing 32 when the second housing 32 is engaged with the first housing 22. Therefore, when the second housing 32 is engaged with the first housing 22, the first terminal 23 can be maintained in the normal position within the first housing 22.

[0045] This embodiment can be implemented with the following modifications. This embodiment and the following variations can be combined with each other within the scope of technical inconsistency. In the above embodiment, the first housing 22 is configured to have a first wall portion 27 and a second wall portion 28 as wall portions, but it is not limited to this, for example, it may be configured to have only one wall portion. In addition, the second housing 32 is configured to have a sealing wall portion 36, but in the case where the first housing 22 has only one wall portion, it may be configured not to have a sealing wall portion 36.

[0046] In the above embodiment, the first housing 22 has a formal locking portion 26c and a temporary locking portion 26d, but it is not limited thereto, for example, it may be configured not to have a temporary locking portion 26d.

[0047] • In the above embodiment, the terminal position guarantee member 25 prevents the second housing 32 from engaging with the first housing 22 when it is configured in a temporary locking position. However, it is not limited to this and may also be configured not to prevent the engagement of the second housing 32.

[0048] • In the above embodiment, the second housing 32 prevents the movement of the terminal position guaranteeing member 25 disposed in the guarantee position when it is engaged with the first housing 22. However, it is not limited to this and may also be configured not to prevent the movement of the terminal position guaranteeing member 25.

[0049] In the above embodiment, the terminal position guaranteeing member 25 is configured to be provided for each of the first terminals 23. However, it is not limited to this and can also be configured to ensure that multiple first terminals 23 are in a normal position using a single terminal position guaranteeing member. For example, it can also be configured such that the first housing 22 has a housing opening that opens in the direction along the third axis Z, through which a single terminal position guaranteeing member can be assembled to a guarantee position that can engage with multiple first terminals 23. Furthermore, in this case, the shielding opening is also configured to open in the direction along the third axis Z.

[0050] In the above embodiment, the first connector 21 has two first terminals 23 and the second connector 31 has two second terminals 33, but the number of first terminals 23 and second terminals 33 can also be changed to one or more other numbers.
