Description

Technical Field

[0001] The present invention relates to a connector unit.

Background Art

[0002] There is known a lever-type connector in which a lever is rotatably supported on a connector body holding terminals, and as the lever rotates, a mating connector is brought close to and fitted into the connector body (see, for example, Patent Document 1).

[0003] FIG. 7 is a diagram showing a conventional lever-type connector 101. This lever-type connector 101 includes a connector body 102 that mates with a mating connector (not shown), a lever 103, and a locking portion 103A provided on the lever 103 that locks the mating connector when the mating connector and the connector body 102 are mated.

[0004] The lever 103 has a U-shape having a pair of arm portions 103B facing each other (only one of the pair of arm portions is shown) and an operation portion 103C connecting the pair of arm portions 103B. When the lever 103 is rotated and the mating connector and the connector body 102 are mated, the locking portion 103A provided on one of the pair of arm portions 103B locks the mating connector, so that the mating state of the mating connector and the connector body 102 is maintained.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, if the lever 103 is gate-shaped, when an operator rotates the lever 103, it is possible that they may not grip it at a position where force is applied evenly to the pair of arm portions 103B, but rather at an uneven position. In such cases, the operator's force is not transmitted evenly to the pair of arm portions 103B, causing the lever 103 to deform in a twisting manner. As a result, the operating portion 103C may interfere with the mating connector before the mating connector is locked by the locking portion 103A provided on one of the pair of arm portions 103B, preventing further pushing. Consequently, the mating connector is not locked by the locking portion 103A, and the mating state between the mating connector and the connector body 102 is not maintained, resulting in a malfunction regarding mating with the mating connector.

[0007] The present invention aims to provide a connector unit that improves the work efficiency of connector mating operations and suppresses problems related to mating with mating connectors. [Means for solving the problem]

[0008] To solve the aforementioned problems and achieve the objective, the invention described in claim 1 is a connector unit comprising a mating connector and a connector body that can be mated with each other, and a lever that is pivotally supported on the connector body and rotated relative to the connector body, wherein the lever is rotatably provided in an initial position and a completed rotation position that brings the mating connector closer to the connector body for mating, the lever has a pair of arm plates that are provided opposite to each other and sandwich the connector body, and a connecting portion that connects the pair of arm plates, one of the pair of arm plates is provided with a locking portion that locks the mating connector in the completed rotation position, the connecting portion has an opposing surface that can abut against the mating connector in the completed rotation position, and the opposing surface is configured to have an inclination such that the base of one of the pair of arm plates is further from the mating connector than the base of the other arm plate. [Effects of the Invention]

[0009] According to the invention described in claim 1, it is possible to improve the work efficiency of the connector mating operation and to suppress problems related to mating with the mating connector. [Brief explanation of the drawing]

[Figure 7] This diagram shows a conventional lever-type connector. [Modes for carrying out the invention]

[0011] Hereinafter, a "connector unit 20" according to an embodiment of the present invention will be described with reference to Figures 1 to 6. Figure 1 is an exploded perspective view showing a lever-type connector 1 that constitutes a connector unit 20 according to one embodiment of the present invention. Figure 2 is a perspective view showing the lever-type connector 1 in its initial position 6A. Figure 3 is a perspective view showing the lever-type connector 1 in its completed rotation position 6B. Figure 4 is a side view showing the lever 6 being rotated to engage the connector body 10 and mating connector 11 of the lever-type connector 1. Figure 5 is a side view showing the lever 6 having rotated further to the completed rotation position 6B, with the connector body 10 and mating connector 11 engaged. In Figure 6, (A) is a vertical cross-sectional view of the connector body 10 and mating connector 11 shown in Figure 5, and (B) is an enlarged view of the main part of (A). Note that the cover 7 that constitutes the lever-type connector 1 is omitted in Figures 4 to 6.

[0012] The connector unit 20 comprises a mating connector 11 and a connector body 10 that can be mated with each other, and a lever 6 that is pivotally supported on the connector body 10 and rotates relative to the connector body 10. When the lever 6 is in the initial position 6A (shown in Figure 2), the mating connector 11 is brought closer to the connector body 10, the lever 6 is rotated, and when the lever 6 is positioned in the completed rotation position 6B (shown in Figure 3), the mating connector 11 and the connector body 10 are mated. The connector body 10 and the lever 6 constitute a lever-type connector 1.

[0013] In this embodiment, arrows X, Y, and Z are in mutually orthogonal directions. The mating direction between the lever-type connector 1 and the mating connector 11 is defined as the Y direction (denoted as the front-rear direction Y), the rotation axis direction of the lever 6 is defined as the Z direction (denoted as the up-down direction Z), and the direction perpendicular to the Y and Z directions is defined as the X direction (denoted as the left-right direction X). In the front-rear direction Y, the Y1 direction (the side of the lever-type connector 1 to the mating connector 11) may be referred to as "forward," and the opposite Y2 direction may be referred to as "rearward." Also, in the up-down direction Z, the Z1 direction (the side of the first arm plate 61A) may be referred to as "upward," and the Z2 direction (the side of the second arm plate 61B) may be referred to as "downward."

[0014] As shown in FIGS. 4 to 6, the mating connector 11 includes a mating terminal 12 (shown in FIG.6(A)) and a mating housing 13 that houses the mating terminal 12.

[0015] As shown in FIG. 6, the mating housing 13 is made of, for example, a resin member and is formed in a rectangular tube shape with the Y direction as the extending direction (axial direction of the tube). As shown in FIG. 6, the mating housing 13 includes a mating wall portion 131 along the XZ plane and a hood portion 132 for fitting the lever-type connector 1 that is continuous with the mating wall portion 131.

[0016] As shown in FIGS. 4 and 5, in this hood portion 132, a connector width 13A into which the lever-type connector 1 to be described later is inserted is an end face along the XZ plane, and is configured to abut against a contact surface 620 of a lever 6 to be described later when the lever-type connector 1 reaches the rotation completion position 6B.

[0017] As shown in FIG. 6, on the mating upper wall 132A of the hood portion 132 along the XY plane, there are provided a guide protrusion (not shown) and an engaging protrusion 133. The guide protrusion is formed to protrude downward from the mating upper wall 132A toward Z2 and is inserted and guided into a cam groove 64 of a lever 6 in the lever-type connector 1.

[0018] The engaging protrusion 133 is formed to protrude downward toward Z2 and is engaged with a locking protrusion 66C of the lever-type connector 1 when the lever-type connector 1 reaches the rotation completion position 6B and the lever-type connector 1 and the mating connector 11 are fitted together.

[0019] The lever-type connector 1 shown in FIGS. 1 to 3 includes a connector body 10 having a plurality of female terminals 2 (shown in FIG. 1), an inner housing 3 (housing) that houses the plurality of female terminals 2, a front mask 5 (holder) that houses the inner housing 3, etc., a lever 6 that is pivotally supported by the inner housing 3 and is pivoted between an initial position 6A (shown in FIG. 2) and a rotation completion position 6B (shown in FIG. 3) where it is fitted to a mating connector 11, and a cover 7 that routes electric wires connected to the plurality of female terminals 2.

[0020] As shown in FIG. 1, the connector body 10 includes an inner housing 3 that houses a plurality of female terminals 2, a spacer 4 that is supported by the inner housing 3 and locks to the female terminals 2, and a front mask 5 that has a temporary locking receiving portion 57 and a main locking receiving portion 58 that are locked to a locking arm 65 of a lever 6 described later.

[0021] As shown in FIG. 1, the female terminal 2 is housed in a terminal housing chamber 30A of the inner housing 3 described later while being connected to the terminal of an electric wire (not shown). The electric wire connected to the female terminal 2 is drawn out rearward Y2 from each terminal housing chamber 30A, inserted through an electric wire insertion port 7a of the cover 7 described later, and led out to one side in the left-right direction X.

[0022] The inner housing 3 is made of an insulating synthetic resin. As shown in FIGS. 1 and 6(A), the inner housing 3 has an upper surface 3A and a lower surface 3B along the XY plane, a front surface 3C, a rear surface 3D, left and right side surfaces 3E, 3F that are continuous with the upper and lower surfaces 3A, 3B, a plurality of terminal housing chambers 30A, and a spacer housing chamber 30B (shown in FIG. 6(A)). Rotation shafts 31 for pivotally supporting the lever 6 are provided on the upper surface 3A and the lower surface 3B, respectively. A spacer opening 30C (shown in FIG. 6(A)) into which a spacer 4 described later is inserted is formed on the lower surface 3B. Cover locking receiving portions 33 that are locked to housing locking portions 71 of the cover 7 described later and mask locking receiving portions 34 that are locked to housing locking portions 59 of the front mask 5 described later are provided on the left and right side surfaces 3E, 3F.

[0023] Multiple terminal housing chambers 30A are arranged in the vertical Z direction and the horizontal X direction. Each terminal housing chamber 30A is formed in the shape of a rectangular cylinder with the Y direction as the extending direction (axial direction of the cylinder) and houses each female terminal 2.

[0024] As shown in Figure 6(A), each terminal housing chamber 30A has openings at the front Y1 and rear Y2. The opening at the front Y1 (hereinafter sometimes referred to as the front opening 30f) allows the mating terminal 12 of the mating connector 11 to be inserted into the terminal housing chamber 30A, while the wire connected to the female terminal 2 is pulled out from the opening at the rear Y2 (hereinafter sometimes referred to as the rear opening 30b). In addition, a terminal lance (not shown) that locks onto the female terminal 2 is provided on the inner surface of each terminal housing chamber 30A. The female terminal 2 is double-locked by this terminal lance and the spacer 4, which will be described later, preventing the female terminal 2 from coming out of each terminal housing chamber 30A.

[0025] As shown in Figure 6(A), the spacer housing chamber 30B is part of the terminal housing chamber 30A and houses the spacer 4, which will be described later.

[0026] The pivot shaft 31 is provided on the upper surface 3A and the lower surface 3B, respectively, and is inserted through the bearing portions 63A and 63B of the lever 6, which will be described later, thereby supporting the lever 6.

[0027] As shown in Figure 6(A), the spacer 4 is housed in the spacer housing chamber 30B by being inserted into the spacer opening 30C formed on the lower surface 3B of the inner housing 3. The spacer 4 is provided to be displaceable between a temporary locking position and a permanent locking position. When the spacer 4 is in the temporary locking position, each female terminal 2 is inserted into each terminal housing chamber 30A and engaged with the lance, thereby temporarily locking each female terminal 2. By displacing the spacer 4 from the temporary locking position to the permanent locking position, each female terminal 2 engages with the spacer 4 and is secondaryly locked.

[0028] The front mask 5 is made of an insulating synthetic resin. As shown in Figure 1, the front mask 5 is formed in a box shape having an upper wall 51 and a lower wall 52 along the XY plane, a front wall 53 continuous with the upper and lower walls 51 and 52, left and right side walls 54, 54, and a receiving opening 55 for receiving the inner housing 3. It also includes a first exposed opening 56A that exposes the tip side of the lever 6, which will be described later, a temporary locking receiving portion 57 provided on the periphery of the first exposed opening 56A that is locked to the locking arm 65 provided on the lever 6 at an initial position 6A, a permanent locking receiving portion 58 that is locked to the locking arm 65 at a rotation completion position 6B, and a second exposed opening 56B that exposes the lock structure 66 provided on the lever 6.

[0029] The front wall 53 is provided with a communication hole 530 at a position that communicates with the front opening 30f of each terminal housing chamber 30A in the inner housing 3. The left and right side walls 54, 54 are provided with housing locking portions 59 that lock into the mask locking receiving portion 34 of the inner housing 3.

[0030] The first exposed opening 56A is formed by cutting out the upper wall 51 and the front wall 53, and is configured to expose the entrance to the cam groove 64 of the lever 6 (described later) and the locking arm 65. A temporary locking receiving portion 57 is provided on the periphery of this first exposed opening 56A, which is to be locked by the locking arm 65 of the lever 6.

[0031] The temporary locking receiver 57 is located Y2 rearward from the front end of the front mask 5 and is configured to include a plane that encompasses the left-right direction X and the up-down direction Z.

[0032] The locking receiver 58 is located at one end in the left-right direction X and at the rear end of the front mask 5, and is provided on the periphery of a rectangular opening that allows the locking arm 65 of the lever 6, which will be described later, to be exposed.

[0033] The second exposed opening 56B is located on the other end in the left-right direction X (opposite the main locking receiving portion 58, with the first exposed opening 56A in between), and is constructed by cutting out the upper wall 51 and the front wall 53, extending rearward X2 to expose the locking structure 66 of the lever 6, which will be described later.

[0034] The lever 6 is made of an insulating synthetic resin. As shown in Figure 1, the lever 6 is configured in a gate-like (C-shape) configuration and comprises a first arm plate 61A (one of a pair of arm plates) and a second arm plate 61B (the other of a pair of arm plates) which are provided facing each other and sandwich the inner housing 3 between them, and a connecting part 62 which connects the first arm plate 61A and the second arm plate 61B.

[0035] The first arm plate 61A is formed in a plate shape and extends along the XY plane (i.e., in the same direction as the upper surface 3A of the inner housing 3 and the upper wall 51 of the front mask 5).

[0036] The first arm plate 61A is provided with a bearing portion 63A that fits onto the pivot shaft 31 of the inner housing 3, a cam groove 64 through which the guide projection of the mating connector 11 is inserted, a locking arm 65 that locks onto the front mask 5, and a locking structure 66 that engages with the engaging projection 133 of the mating connector 11.

[0037] The first bearing portion 63A is formed as a through-hole, through which the pivot shaft 31 of the inner housing 3 is inserted. As a result, the lever 6 is pivotally supported relative to the inner housing 3 with the pivot shaft 31 and the bearing portion 63A (63B) as its center. Note that the bearing portion 63A does not have to be a through-hole, and may be formed as a recess on the inner surface of the first arm plate 61A. Alternatively, the bearing portion 63A of the first arm plate 61A may be formed as a convex shape, and the pivot shaft 31 of the inner housing 3 may be formed as a through-hole or as a recess.

[0038] The cam groove 64 is formed in the first arm plate 61A in the shape of a concave slit, through which the guide projection of the mating connector is inserted, and is configured to have a shape (track) that brings the guide projection closer to the first bearing portion 63A when the lever 6 is rotated.

[0039] As shown in Figures 1 and 2, the locking arm 65 is provided at the end of the first arm plate 61A that is away from the connecting portion 62. This locking arm 65 is composed of a cantilever-shaped arm 65A that can bend in the vertical direction Z, and a locking projection 65B that protrudes upward Z1 (opposite side from the second arm plate 61B) from the free end of the arm 65A.

[0040] As shown in Figure 1, the arm 65A is formed by forming a slit S in the first arm plate 61A. The slit S is formed by cutting out the edge of the first arm plate 61A away from the connecting portion 62, and extends linearly toward the connecting portion 62.

[0041] As shown in Figures 2 and 3, the locking structure 66 is provided at the end of the first arm plate 61A near the connecting portion 62, and when the lever 6 is in the rotation completion position 6B, as shown in Figure 6, it engages with the engaging projection 133 of the mating connector 11, thereby maintaining the mated state between the connector body 10 and the mating connector 11.

[0042] As shown in Figure 2, the locking structure 66 comprises a lever arm 66B provided between a pair of slit portions 66A, 66A in the first arm plate 61A, and a locking projection 66C provided on the lever arm 66B and capable of engaging with the engaging projection 133 of the mating connector 11. The pair of slit portions 66A, 66A are formed by cutting out the rear end of the first arm plate 61A and extending forward Y1 when the lever 6 is in the rotation completion position 6B. The locking projection 66C is provided between the pair of slit portions 66A, 66A and is provided projecting upward Z1 at the midpoint in the front-rear direction Y.

[0043] As shown in Figure 1, the second arm plate 61B is provided with a second bearing portion 63B that fits onto the pivot shaft 31 of the inner housing 3.

[0044] As shown in Figures 3 and 5, the connecting portion 62 is configured as a plate shape with its longitudinal direction being the direction in which the first arm plate 61A and the second arm plate 61B face each other (up and down direction Z), and includes a contact surface 620 (opposing surface) that can contact the connector opening 13A of the mating connector 11 when the lever 6 is in the rotation completion position 6B, and an operating portion 621 that is positioned opposite the contact surface 620.

[0045] The base 62A (sometimes referred to as "one base") of the first arm plate 61A is continuously provided at one end of the contact surface 620, and the base 62B (sometimes referred to as "the other base") of the second arm plate 61B is continuously provided at the other end of the contact surface 620. The contact surface 620 extends away from the tip, sandwiching the bases 62A and 62B of the pair of arm plates 61A and 61B.

[0046] Furthermore, the contact surface 620 is configured with an inclination such that, when the lever 6 is in the rotation completion position 6B, the base 62B of the second arm plate 61B is further from the mating connector 11 than the base 62A of the first arm plate 61A. As a result, as shown in Figure 4, even if the operator fitting the connector body 10 and the mating connector 11 presses the operating part 621 of the lever 6 at a position F close to the base 62B of the second arm plate 61B, it is possible to prevent the base 62B of the second arm plate 61B from coming into contact with the connector opening 13A of the mating connector 11 before the locking projection 66C of the lever 6 engages with the engaging projection 133 of the mating connector 11.

[0047] The cover 7 is made of an insulating synthetic resin. As shown in Figures 1 and 2, the cover 7 has a wire insertion opening 7a and a mounting opening 7b for the inner housing 3, and comprises a cover body 70 that covers the rear surface Y2 of the inner housing 3, and a housing locking portion 71 provided on the cover body 70 that locks into the cover locking receiving portion 33 of the inner housing 3.

[0048] Next, the assembly procedure for lever-type connector 1 will be explained.

[0049] First, the inner housing 3 is brought close to the first arm plate 61A and the second arm plate 61B of the lever 6, and the inner housing 3 is sandwiched between the first arm plate 61A and the second arm plate 61B. As a result, the bearing portions 63A and 63B are pivotally supported on each pivot shaft 31, and the lever 6 is pivotally supported on the inner housing 3. In this way, the inner housing 3 with the lever 6 is assembled.

[0050] Next, the inner housing 3 with the lever 6 is brought close to the housing opening 55 of the front mask 5 and inserted. This connects the front opening 30f of each terminal housing chamber 30A in the inner housing 3 with the communication hole 530, and the mask locking receiving portion 34 of the inner housing 3 locks into the housing locking portion 59 of the front mask 5. The lever 6 is also positioned at the rotation completion position 6B, where the locking projection 65B locks into the main locking receiving portion 58 of the front mask 5. In this way, the inner housing 3 with the lever 6 is housed in the front mask 5.

[0051] Next, the spacer 4 is positioned in the temporary locking position of the inner housing 3, and the female terminals 2 connected to the electric wires are inserted into the terminal housing chamber 30A of the inner housing 3 from the rear opening 30b toward the front Y1. This locks the female terminals 2 into the terminal lances. After this, the spacer 4 is displaced from the temporary locking position to the permanent locking position. As a result, each female terminal 2 is double-locked by the terminal lance and the spacer 4, preventing the female terminals 2 from coming out of each terminal housing chamber 30A. At this time, the electric wires connected to the female terminals 2 are pulled out from the inner housing 3.

[0052] Next, the mounting opening 7b of the cover 7 is brought close to the inner housing 3 with the lever 6, and the wires pulled out from the inner housing 3 are inserted into the wire insertion opening 7a of the cover 7. This locks the cover locking receiver 33 with the housing locking part 71. In this way, the cover 7 is assembled to the inner housing 3 with the lever 6. At this time, the wires pulled out from the inner housing 3 are led out to one side in the left-right direction X.

[0053] Next, the lever 6 is rotated from the completed rotation position 6B to the initial position 6A. The locking arm 65 is released from the main locking receiving portion 58 on the front mask 5, and the lever 6 becomes rotatable. As it rotates further, the locking arm 65 locks onto the temporary locking receiving portion 57 of the front mask 5, as shown in Figure 2. In this state, the locking arm 65 is locked onto the temporary locking receiving portion 57, which restricts the rotation of the lever 6 and holds it in the initial position 6A. With the lever 6 positioned in the initial position 6A in this way, the assembly of the lever-type connector 1 is completed.

[0054] Next, when mating the connector body 10 of the lever-type connector 1 with the mating connector 11, with the lever 6 of the lever-type connector 1 in its initial position 6A, the connector body 10 is brought close to the hood portion 132 of the mating connector 11 and inserted. This causes the guide projection of the mating connector 11 to pass through the cam groove 64 of the lever 6, and the guide projection is positioned near the entrance of the cam groove 64.

[0055] Next, the operating part 621 of the lever 6 is pressed to rotate the lever 6. As the pressing (rotation) progresses, the lever-type connector 1 is displaced from its initial position 6A. As the pressing progresses, the lock projection 66C of the lock structure 66 comes into contact with the engagement projection 133 of the mating connector 11, and the lever arm 66B of the lock structure 66 bends downward Z2, pushing the lock projection 66C downward Z2 of the engagement projection 133. As the pressing progresses further, the lock projection 66C overcomes the engagement projection 133. Once the lock projection 66C overcomes the engagement projection 133, the lever arm 66B elastically returns to its original shape. With the lock projection 66C positioned in front Y1 of the engagement projection 133, the lock projection 66C engages with the engagement projection 133 (as shown in Figures 6(A) and 6(B)). Almost simultaneously, the guide projection is positioned at the far end of the cam groove 64, and the lever 6 reaches the rotation completion position 6B where the locking arm 65 is locked into the locking receiving portion 58, thereby mating the connector body 10 with the mating connector 11. The mating state between the connector body 10 and the mating connector 11 is maintained by the lock projection 66C being engaged with the engagement projection 133.

[0056] Here, when an operator who is mating the connector body 10 with the mating connector 11 presses the operating part 621 of the lever 6 and rotates the lever 6, as shown in Figure 4, even if the operator presses the operating part 621 of the lever 6 at a position F close to the base 62B of the second arm plate 61B, the contact surface 620 is configured with an inclination such that the base 62B of the second arm plate 61B is further from the connector opening 13A of the mating connector 11 than the base 62A of the first arm plate 61A. As a result, the operating part 621 is pushed in along the inclination of the contact surface 620 so as to approach the connector opening 13A of the mating connector 11.

[0057] This allows the locking projection 66C of the lever 6 to engage with the engaging projection 133 of the mating connector 11 before the base 62B of the second arm plate 61B on the contact surface 620 interferes with the connector opening 13A of the mating connector 11. In other words, the lever 6 can prevent the base 62B of the second arm plate 61B from interfering with the connector opening 13A of the mating connector 11 before the locking projection 66C of the lever 6 engages with the engaging projection 133 of the mating connector 11.

[0058] According to this, the locking projection 66C of the lever 6 will be reliably engaged with the engaging projection 133 of the mating connector 11, and a mating guarantee state will be achieved in which the mated state between the connector body 10 and the mating connector 11 is maintained. In this way, the contact surface 620 is configured with an inclination such that the base 62B of the second arm plate 61B is further away from the mating connector 11 than the base 62A of the first arm plate 61A, thereby improving the work efficiency of the connector mating operation and suppressing problems related to mating with the mating connector 11.
