Connectors and Connector Assemblies

Abstract

A connector and a connector assembly are provided, which can prevent the secondary contact from being engaged before a sliding operation and can reliably perform a rotation operation and a subsequent sliding operation. The secondary housing (13) slides up and down relative to the main housing (11). The secondary housing (13) is provided with a mis-engagement prevention portion (132) extending downward in a cantilever beam shape. Even when the secondary housing (13) is in a state of sliding downward at the beginning of engagement, the mis-engagement prevention portion (132) abuts against a mis-engagement prevention protrusion (213) of a housing (21) of a second connector (20), thereby staying at its height position. Thus, mis-engagement is prevented. After the rotation operation of the rod (15) is terminated, the rod (15) is slidably operated. At this time, the mis-engagement prevention portion (132) is bent and the abutment against the mis-engagement prevention protrusion (213) is disengaged, and the secondary contact engages.

Description

Technical Field

[0001] The present invention relates to a connector and a connector assembly which are installed as a part of an electric vehicle or a hybrid vehicle, for example, to relay electric current supplied from a power supply system. Background Art

[0002] In electric vehicles or hybrid vehicles, a connector device capable of flowing a large current such as 100 amperes is used. In maintenance and other scenarios, it is sometimes necessary to remove the mating (two) connectors in the connector device. In this case, in order to avoid electric shock, it is necessary to remove the connector after stopping the flow of the current that is flowing. Therefore, a structure that reliably stops the flow of current before removing the mating connector is required.

[0003] Patent document 1 discloses a connector device, which includes a rod that engages two connectors by rotating, or releases the engaged state of the connectors by rotating in the opposite direction. In addition to a main contact for passing a large current, the connector device also includes an auxiliary contact for detecting the engagement or removal of the connector. Moreover, the rod has a structure that slides in addition to rotating when the connector is engaged. The main contact is engaged by rotating the rod, and the auxiliary contact is engaged by sliding thereafter. The engagement of the connector is detected by the engagement of the auxiliary contact, and then a large current flows through the main contact. When releasing the engagement, the rod is first slid. As a result, the engagement of the auxiliary contact is disengaged, thereby cutting off the large current. Thereafter, the rod is rotated to remove the connector. With this structure, the connector is detached after the large current is reliably cut off.

[0007] [Problems to be solved by the invention]

[0008] In the above-mentioned connector device having a main contact and an auxiliary contact, after the main contact is engaged by the rotation operation of the rod, it is necessary to reliably engage the auxiliary contact by the sliding operation. Here, in the connector device having a main contact and an auxiliary contact, it is necessary to operate the main contact and the auxiliary contact separately. Therefore, due to the structure of the connector device, the following fault may occur: some erroneous or unexpected force acts, and the auxiliary contact engages before the connector is fully engaged, so that a large current begins to flow. In addition, after the rotation operation of the rod, a fault may occur in which the sliding operation cannot be performed.

[0009] An object of the present invention is to provide a connector and a connector assembly which can prevent the coupling of auxiliary contacts before the sliding operation of a lever and can reliably perform the rotation operation of the lever and the subsequent sliding operation.

[0010]

Solution to the problem

[0011] The connector of the present invention that achieves the above-mentioned object is mated with a mating connector in a predetermined mating direction, and is characterized by comprising:

[0012] main housing;

[0013] A first main contact member for conducting the main power source provided in the main housing;

[0014] A sub-housing supported by the main housing so as to be slidable in a mating direction of the connector and the mating connector;

[0015] A first auxiliary contact provided in the auxiliary housing for detecting the mating of the connector with the mating connector; and

[0016] an operating member rotatably and slidably supported by the main housing,

[0017] When the operating member is rotated from the first position to the second position, the main housing moves closer to the other connector.

[0018] When the operating member reaches the second posture, the first main contact is electrically connected to the second main contact for conducting the main power supply of the other connector.

[0019] When the operating member slides from the second posture in a direction different from the mating direction, the auxiliary housing further moves in the mating direction relative to the main housing, and the first auxiliary contact is connected to the second auxiliary contact for mating detection of the mating connector.

[0020] The first secondary contact has an erroneous mating prevention portion, which, when the connector slides in the mating direction relative to the main housing during incomplete mating before the connector is fully mated with the mating connector, abuts against the mating connector to prevent the first secondary contact from contacting the second secondary contact.

[0021] The incorrect fitting preventing portion releases the interference with the mating connector when the operating member slides from the second posture, thereby bringing the first sub-contact into conduction with the second sub-contact.

[0022] Here, in the connector of the present invention, the erroneous mating preventing portion may extend in the mating direction in a cantilever beam shape and have a front end portion that abuts against a housing of the mating connector.

[0023] The incorrect mating preventing portion is pushed in the mating direction by the sliding of the operating member from the second posture and is bent in a direction intersecting the mating direction, thereby releasing the interference of the front end portion with the housing of the mating connector.

[0024] In addition, the connector assembly of the present invention that achieves the above-mentioned object is a connector assembly comprising a first connector and a second connector that fit together, characterized in that:

[0025] The first connector comprises:

[0026] main housing;

[0027] A first main contact member for conducting the main power source provided in the main housing;

[0028] a first sub-housing supported by the main housing so as to be slidable in a mating direction in which the first connector and the second connector are mated;

[0029] a first auxiliary contact provided in the first auxiliary housing and used for detecting the mating of the first connector and the second connector; and

[0030] an operating member rotatably and slidably supported by the main housing,

[0031] The second connector comprises:

[0032] a second shell;

[0033] A second main contact for conducting the main power source provided in the second housing; and

[0034] a second pair of contacts for detecting the engagement of the first connector with the second connector,

[0035] When the operating member is rotated from the first position to the second position, the main housing moves closer to the second connector.

[0036] When the operating member reaches the second posture, the first main contact member and the second main contact member are connected.

[0037] When the operating member slides from the second posture in a direction different from the mating direction, the first sub-housing moves further in the mating direction relative to the main housing, and the first sub-contact is electrically connected to the second sub-contact.

[0038] The second housing has a second mis-mating prevention portion, which, when the first connector and the second connector are incompletely mated before the first connector is completely mated with the second connector, abuts against the first sub-housing when the first sub-housing slides relative to the main housing in the mating direction, thereby preventing the first sub-contact from contacting the second sub-contact.

[0039] The first auxiliary contact has a first mis-mating prevention portion, which, when the first auxiliary contact slides in the mating direction relative to the main housing during the incomplete mating, abuts against the second mis-mating prevention portion to prevent the first auxiliary contact from contacting the second auxiliary contact, and the abutment against the second mis-mating prevention portion is released by sliding the operating member from the second posture, thereby making the first auxiliary contact conductive with the second auxiliary contact.

[0040] [Effects of the Invention]

[0041] The connector and connector assembly of the present invention are provided with the above-mentioned mis-mating prevention structure. Therefore, according to the present invention, the auxiliary contact is prevented from being engaged before the sliding operation. In addition, according to the present invention, the rotation operation and the subsequent sliding operation can be reliably performed. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Hereinafter, embodiments of the present invention will be described.

[0054] Figure 1 1 is a perspective view of the appearance of the first connector 10 .

[0055] in addition, Figure 2 is an exploded perspective view of the first connector 10 .

[0056] The first connector 10 corresponds to an example of the connector of the present invention and an example of the first connector constituting the connector assembly of the present invention.

[0057] The first connector 10 includes a main housing 11 and a main contact 12. The main housing 11 includes an opening at least in a portion, and may also have a shape that is widely opened in the upper and lower parts. For example, a large current of 100 amperes flows through the main contact 12. The main contact 12 includes a fuse 121 for preventing an overcurrent exceeding its standard. The main housing 11 includes the main contact 12, which is configured, accommodated or fixed in the main housing 11, for example, through the opening. The main contact 12 corresponds to an example of the so-called first main contact in the present invention.

[0058] In addition, the first connector 10 includes a sub-shell 13 and a sub-contact 14. The sub-contact 14 is a circuit terminal for detecting mating. The sub-shell 13 includes the sub-contact 14, which is pressed into the sub-shell 13, for example. Here, the structure of the combined sub-shell 13 and the sub-contact 14 provided in the sub-shell 13 is referred to as a sub-connector 13A. The sub-connector 13A is arranged in the main shell 11 so as to slide freely up and down with the connector. The sub-shell 13 and the sub-contact 14 are respectively equivalent to one example of the first sub-shell and the first sub-contact in the present invention. In addition, in the description of the embodiment, for convenience, the side of the first connector 10 in the state where the first connector 10 and the second connector 20 are mated is referred to as the upper side, and the side of the second connector 20 is referred to as the lower side.

[0059] The first connector 10 also includes a rod 15. Figure 1As shown, the rod 15 is rotatably and slidably mounted on the main housing 11. For example, the rod 15 has two side surfaces connected by a handle, and is mounted in a manner that the two side surfaces span the main housing 11. The rod 15 can be rotated and slid by the operation of the user. On the rod 15, a rotating cam groove 151 and a sliding guide groove 152 are formed on at least one of the two side surfaces spanning the rod 15. In addition, a sliding cam groove 153 is formed on at least one of the two side surfaces of the rod 15 spanning the main housing 11, which allows the sub-housing 13 to slide through a sliding operation. A boss 111 is provided on the main housing 11, which serves as the central axis of rotation of the rod 15. As shown in FIG. Figure 1 As shown, the boss 111 enters the slide guide groove 152. The boss 111 becomes the central axis of rotation of the rod 15 and serves as a guide for the sliding of the rod 15. In addition, a slide cam pin 131 that enters the slide cam groove 153 is formed in the auxiliary housing 13. The rod 15 corresponds to an example of the so-called operating member in the present invention.

[0060] The first connector 10 may further include a cover 16. After the main contacts 12 and the sub-connector 13A are arranged in the main housing 11, the cover 16 is put on the main housing 11. When the cover 16 is put on the main housing 11, the first connector 10 becomes a connector having a mating opening opened on one side.

[0061] Figure 3 is a perspective view of the second connector 20 .

[0062] in addition, Figure 4 is an exploded perspective view of the second connector 20 .

[0063] The second connector 20 is an example of a so-called counterpart connector in the connector of the present invention, and corresponds to an example of a second connector constituting the connector assembly of the present invention.

[0064] The second connector 20 includes a housing 21. The housing 21 has a mating opening for mating with the first connector 10 and facing the mating opening of the first connector 10. For the mating state of the second connector 10 and the second connector 20, refer to Figure 7 (A) to Fig.11 (B) and the following description corresponding thereto. In addition, a cam pin 212 protrudes from the side surface of the housing 21, and the cam pin 212 enters the rotation cam groove 151 provided in the lever 15 of the first connector 10. The housing 21 corresponds to an example of the second housing in the present invention.

[0065] The second connector 20 is provided with a main contact 22. The main contact 22 is a circuit terminal through which a large current flows in conjunction with the main contact 12 of the first connector 10. The main contact 22 corresponds to an example of a second main contact in the present invention.

[0066] In addition, the second connector 20 is provided with an interlock harness 23. The interlock harness 23 is provided with a sub-connector 23A, which is composed of a sub-housing 231 and a sub-contact 232 provided inside the sub-housing 231. The sub-contact 232 in the sub-housing 231 constituting the sub-connector 23A is equivalent to an example of the so-called second sub-contact in the present invention. The sub-connector 23A is a connector for detecting mating, and can transmit mating and removal signals to a controller not shown in the figure through the interlock harness 23.

[0067] Furthermore, the second connector 20 includes a fuse holding spring 24. The fuse holding spring 24 is a component that holds the fuse 121 of the main contact 12 of the first connector 10 when the second connector 20 is mated with the first connector 10.

[0068] exist Figure 4 A screw 25 and a collar 26 for tightening the components are further shown, but their description is omitted.

[0069] Figure 5 (A) to (B) are an enlarged perspective view (A) and an enlarged side view (B) of the sub-housing 13 included in the first connector 10 .

[0070] The auxiliary housing 13 is provided with a mis-mating prevention portion 132. The mis-mating prevention portion 132 extends in a cantilever beam shape in the direction of the mating between the first connector 10 and the second connector, and is provided with a slope 132a at the front end. In addition, the mating direction may also be the up-down direction. In addition, a convex portion 132b protruding laterally relative to the up-down direction is formed on the mis-mating prevention portion 132. The function of the mis-mating prevention portion 132 will be described later. The mis-mating prevention portion 132 is equivalent to an example of a so-called mis-mating prevention portion in the connector of the present invention, and an example of a so-called first mis-mating prevention portion in the connector assembly of the present invention. In addition, the slope 132a is equivalent to an example of a so-called front end portion in the present invention.

[0071] Figure 6 (A) to (C) are a plan view (A), a cross-sectional view (B), and an enlarged view (C) of a circle R portion of the cross-sectional view (B) of the housing 21 constituting the second connector 20 .

[0072] The housing 21 is provided with an erroneous fitting prevention protrusion 213 that protrudes upward. Figure 5The inclined surface 132a at the front end of the misfitting prevention portion 132 of the auxiliary housing 13 shown in the figure abuts against the top surface 213a formed on the inclined surface of the misfitting prevention protrusion 213, thereby preventing the auxiliary contact 14 of the first connector 10 and the auxiliary contact 232 of the second connector 20 from being coupled to each other. In addition, a recess 213b is formed on the side surface of the misfitting prevention protrusion 213. The misfitting prevention protrusion 213 is equivalent to an example of the second misfitting prevention portion in the present invention.

[0073] Next, the operation of the two connectors when they are mated is described. Figure 7 In the drawings after (A), the sub-contacts 14 and the sub-connector 23A of the second connector 20 are omitted in order to easily understand the present embodiment. The sub-housing 13 is necessary for explaining the present embodiment and is therefore not shown.

[0074] Figure 7 (A) to (B) are a side view (A) and a cross-sectional view (B) showing an initial state of fitting in which the first connector 10 is stacked on the second connector 20. Figure 7 (A) shows Figure 1 The side opposite to the side shown.

[0075] Here, the rod 15 is still in a state of being kept vertically upright, and is in a rotation starting position. Figure 7 As shown in (A), the cam pin 212 of the housing 21 of the second connector 20 enters the rotating cam groove 151. Figure 7 As shown in (B), the auxiliary housing 13 is located directly above the mis-mating prevention protrusion 213 provided on the housing 21 of the second connector 20. At this time, the auxiliary contact 14 of the first connector 10 is not engaged with the auxiliary contact 232 of the second connector 20. The auxiliary housing 13 is in a normal initial position before mating.

[0076] The Figure 7 The state of the first connector 10 and the second connector 20 shown in (A) and (B) is referred to as an initial state of normal mating.

[0077] Figure 8 (A) to (B) are a side view (A) and a cross-sectional view (B) showing an initial state of abnormal fitting of the first connector 10 and the second connector 20 when the sub-housing 13 is in a position deviated from the normal initial position (abnormal initial position).

[0078] As compared Figure 7 (A) and Figure 8 (A) then we can know: Figure 7 (A) Compared with Figure 8In (A), the slide cam pin 131 provided on the auxiliary housing 13 moves downward. Figure 7 (B) and Figure 8 (B) As can be seen, the sub-connector 13 moves downward. However, only the sub-housing 13 moves downward, and the elements other than the sub-connector 13 of the first connector 10 are moved downward. Figure 7 (A), (B) and Figure 8 (A) and (B) are at the same height.

[0079] For example, the lever 15 is in the rotation start position.

[0080] The auxiliary housing 13 is supported by the main housing 11 so as to slide freely up and down. Figure 7 The auxiliary housing 13 at the height shown in (A) and (B) may move downward until Figure 8 In the case of this embodiment, the structure is such that even if the auxiliary housing 13 moves to an abnormal initial position in the abnormal fitting initial state, the sliding action of the rod 15 is prevented (hereinafter, refer to Fig.10 (A) to Fig.11 (B) and their explanatory text) before the auxiliary contacts 14 and 232 are connected to each other (the first connector 10 and the second connector 20 are incorrectly mated). In addition, the auxiliary contacts 14 and 232 are always connected to each other by the sliding action of the lever 15.

[0081] Next, the operator should keep the auxiliary housing 13 moving downward until Figure 8 The operation of each component when the first connector 10 and the second connector 20 are fitted together in the state not in the normal initial position shown in (A) and (B) will be described.

[0082] Fig. 9 (A) to (B) are a side view (A) and a cross-sectional view (B) showing a state in the middle of fitting.

[0083] In this Fig. 9 From (A) to (B), the lever 15 is rotated halfway. At this time, the cam pin 212 entering the cam groove 151 is pushed downward as the cam groove 151 is rotated, and the main housing 11 of the first connector 10 moves closer to the mating completion position relative to the second connector 20 (i.e., moves downward in the figure). The main contact 12 (see Figure 1 ) also moves downward together with the main housing 11. Furthermore, the auxiliary housing 13 also moves downward together with the main housing 11. Figure 8 (A) and Fig. 9(A), the relative position of the slide cam pin 131 of the auxiliary housing 13 with respect to the main housing 11 is the same. It can be seen from this that the auxiliary housing 13 moves downward together with the main housing 11.

[0084] If the rod 15 is rotated from the rotation start position until the Fig. 9 (A) and (B) are the angles shown. Fig. 9 As shown in (B), the inclined surface 132a (see Figure 5 ) comes into contact with the top surface 213a of the mis-fitting prevention protrusion 213 (see Figure 6 (C)) status.

[0085] Fig.10 (A) and (B) are a side view (A) and a cross-sectional view (B) showing a state where the lever is rotated to the rotation end position.

[0086] If Fig. 9 (A) and (B) are compared, the main housing 11 is in a position further down toward the second connector 20 along with the shape of the rotating cam groove 151. Fig.10 As shown in (B), regarding the auxiliary housing 13, the erroneous fitting preventing portion 132 abuts against the erroneous fitting preventing protrusion 213, and stays in contact with the auxiliary housing 13. Fig. 9 (B) The same height position. If the erroneous mating prevention portion 132 and the erroneous mating prevention protrusion 213 are not formed, Fig. 9 (B) The state advances to Fig.10 In the state (B), the auxiliary housing 13 moves further downward together with the main housing 11. That is, there is a risk that the lever 15 slides normally and the auxiliary contacts 14 and 232 are mistakenly detected as being engaged with each other. In the case of this embodiment, the auxiliary housing 13 stays at a height position where the mis-engagement prevention portion 132 abuts against the mis-engagement prevention protrusion 213, so there is no risk of mis-detection. In this way, the auxiliary housing 13 is moved downward when the lever 15 moves from the main housing 11. Fig. 9 Move the angles shown in (A) and (B) until Fig.10 During the final angles shown in (A) and (B), the height position of the auxiliary housing 13 is stationary. Fig.10 (A) and (B) show the final angles, the auxiliary housing 13 becomes the same as that in the initial state of engagement. Figure 7 (A) and (B) are the same as the normal initial position. Fig.10 At the final angles shown in (A) and (B), the slide cam pin 131 enters the slide cam groove 153 .

[0087] Afterwards, if Fig.10(A) Slide the operating rod 15 in a direction different from the direction in which the two connectors are mated, as in the direction of arrow A shown in FIG. 1. For example, slide the rod 15 in a direction intersecting the mating direction. During this sliding operation, the cam pin 212 entering the rotating cam groove 151 moves approximately horizontally relative to the rod 15 in the horizontally extending portion of the rotating cam groove 151. In addition, the sliding guide groove 152 also extends horizontally, and the boss 111 entering the sliding guide groove 152 also moves approximately horizontally relative to the rod 15. That is, the height of the main housing 11 is hardly changed by the sliding of the rod 15 in the direction of arrow A, and remains at approximately the same height as before the sliding.

[0088] On the other hand, the slide cam groove 153 extends obliquely downward. The slide cam pin 131 of the auxiliary housing 13 enters the slide cam groove 153. Therefore, if the rod 15 is slid in the direction of the arrow A, the auxiliary housing 13 moves further downward.

[0089] Fig.11 (A) and (B) are a side view (A) and a cross-sectional view (B) showing a state where the rod is slid in the direction of arrow A.

[0090] like Fig.11 As shown in (B), the auxiliary housing 13 is in contact with Fig.10 (B) Compared to a further down position.

[0091] If from Fig.10 In the state shown in (A) and (B), the rod 15 is slid in the direction of arrow A. Once the misfitting prevention portion 132 of the auxiliary housing 13 is bent in a direction intersecting the fitting direction, the interference with the misfitting prevention protrusion 213 is disengaged. At this time, the misfitting prevention portion 132 of the auxiliary housing 13 can also be bent in the lateral direction. Moreover, the rod 15 is further slid in the direction of arrow A and moves downward, and finally the convex portion 132b (refer to Figure 5 ) enters the recessed portion 213b on the side of the mis-fitting prevention protrusion 213 (see Figure 6 ).

[0092] Thus, the present embodiment includes the erroneous fitting stopper 132 and the erroneous fitting preventing protrusion 213, thereby preventing erroneous fitting. In addition, in the present embodiment, the lever 15 is correctly operated regardless of the height position of the auxiliary housing 13 in the initial fitting state.

[0093] When removing the connector from the mating state, the operation is performed in the opposite direction to the above-mentioned mating operation. That is, first, the rod 15 is moved to Fig.11 (A) Slide in the direction of arrow B. Then, only the auxiliary housing 13 is lifted until Fig.10The position shown. At this stage, the sub-connectors 13A and 23A are disengaged from each other, and the disassembly operation is detected. To cut off the large current passing through the main contacts 12 and 22, a certain amount of time is required from the detection of the disassembly operation (although a short time). In this embodiment, the main contacts 12 and 22 are disengaged by the rotation operation after the sliding operation of the rod 15. Even if the rotation operation is performed next after the sliding operation, it is sufficient to ensure a certain amount of time for cutting off the large current.

[0094] After the lever 15 is slid in the direction of arrow B, the lever 15 is moved from Fig.11 (A) The posture shown is facing Figure 7 The first connector 10 can be detached from the second connector 20 by rotating the first connector 10 in the posture shown in (A).

When the operating member slides from the second posture in a direction different from the mating direction, the first sub-housing further moves in the mating direction relative to the main housing, and the first sub-contact is electrically connected to the second sub-contact. The second housing has a second mis-mating prevention portion, which, when the first connector and the second connector are incompletely mated before the first connector is completely mated with the second connector, abuts against the first sub-housing when the first sub-housing slides relative to the main housing in the mating direction, thereby preventing the first sub-contact from contacting the second sub-contact. The first secondary contact has a first mis-mating preventing portion, which abuts against the second mis-mating preventing portion to prevent the first secondary contact from contacting the second secondary contact when the first secondary contact slides relative to the main housing in the mating direction during the incomplete mating, and the abutment against the second mis-mating preventing portion is released by the sliding of the operating member from the second posture, thereby causing the first secondary contact to be conductively connected to the second secondary contact. The second mis-mating preventing portion (213) extends in a cantilever beam shape in a mating direction between the second connector (20) and the first connector (10). The first mis-mating preventing portion (132) extends in a cantilever beam shape in a mating direction of the first connector (10) and the second connector (20).

2. The connector assembly according to claim 1, characterized in that: The first mis-fitting prevention portion has a front end portion that abuts against the second connector as a mating connector. The first incorrect fitting preventing portion is pushed in the fitting direction by the sliding of the operating member from the second posture and is bent in a direction intersecting the fitting direction, thereby releasing interference with the second housing of the second connector.

3. The connector assembly according to claim 1 or claim 2, characterized in that: The first mis-fitting prevention portion has a first convex portion (132b) having a first inclined surface (132a) protruding in the transverse direction at the front end portion. The second mis-fitting prevention portion has a second convex portion (213b) having a second inclined surface (213a) protruding in the transverse direction at the front end portion. The first inclined surface (132a) abuts against the second inclined surface (213a), thereby preventing the first secondary contact piece (14) of the first connector (10) from being combined with the second secondary contact piece (232) of the second connector (20).
