Description

Technical Field

[0001] This invention relates to connector units. Background Technology

[0002] A rod-type connector is known in which the rod is rotatably supported on a connector body that holds terminals, and as the rod rotates, the other connector approaches the connector body and engages (see, for example, Patent Document 1).

[0003] Figure 7 This is a diagram showing a conventional rod connector 101. The rod connector 101 includes: a connector body 102 that engages with a counterpart connector (not shown); a rod 103; and a locking portion 103A disposed on the rod 103 and locking with the counterpart connector when the counterpart connector engages with the connector body 102.

[0004] The lever 103 is a gate-shaped structure having a pair of opposing arms 103B (only one of the arms is shown in the figure) and an operating part 103C connecting the pair of arms 103B. When the lever 103 rotates to engage the other connector with the connector body 102, a locking part 103A provided on one of the arms 103B engages the other connector, thereby maintaining the engagement state between the other connector and the connector body 102.

[0008] The technical problem that the invention aims to solve

[0009] However, when the lever 103 is gate-shaped, if the operator rotates the lever 103, it is considered that the force is not evenly applied to the pair of arms 103B, but rather the operation is performed from a biased position. Furthermore, in this case, the following situation exists: the operator's operating force is not evenly transmitted to the pair of arms 103B, the lever 103 deforms in a torsional manner, and before the opposite connector is locked by the locking part 103A of one of the arms 103B, the operating part 103C interferes with the opposite connector, preventing further insertion. Since the opposite connector is not locked by the locking part 103A, the mating state between the opposite connector and the connector body 102 cannot be maintained, resulting in a state with defects related to the mating of the opposite connector.

[0010] The purpose of this invention is to provide a connector unit that improves the efficiency of connector mating operations while suppressing adverse conditions related to mating with the other connector.

[0011] Technical means for solving problems

[0012] To solve the aforementioned problems and achieve the objective, the invention described in technical solution 1 is a connector unit comprising: a mating connector and a connector body capable of mutual engagement; and a rod supported on the connector body and rotatable relative to the connector body. The rod is configured to rotate to an initial position and a completed rotation position in which the mating connector approaches and engages with the connector body. The rod has: a pair of arm plates disposed opposite each other and clamping the connector body; and a connecting portion connecting the pair of arm plates to each other. 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 a facing surface that can face and abut against the mating connector in the completed rotation position. The facing surface is configured to have an inclination such that the root of the other of the pair of arm plates is located further away from the mating connector than the root of the first one.

[0021] Figure 7 This is a diagram showing an existing rod-type connector. Detailed Implementation

[0022] The following is based on Figures 1-6 The "connector unit 20" of the embodiment of the present invention will be described. Figure 1 This is an exploded perspective view showing the rod connector 1 that constitutes the connector unit 20 according to one embodiment of the present invention. Figure 2 This is a perspective view showing the rod connector 1 in its initial position 6A. Figure 3 This is a perspective view showing the rod connector 1 in the completed rotation position 6B. Figure 4 This is a side view showing the situation where the rod 6 is rotated so that the connector body 10 of the rod connector 1 is engaged with the other connector 11. Figure 5 This is a side view showing the state after the rod 6 continues to rotate and is located at the completed rotation position 6B, and the connector body 10 and the other connector 11 are engaged. Figure 6 (A) is Figure 5 The longitudinal sectional view of the connector body 10 and the other connector 11 shown is shown. Figure 6 (B) is an enlarged representation. Figure 6 A diagram of the main part of (A). Additionally, in Figures 4-6 In the original text, the cover 7 that constitutes the rod connector 1 is omitted.

[0023] Connector unit 20 includes: a mating connector 11 and a connector body 10 capable of interlocking, and a rod 6 axially supported on the connector body 10 and rotatable relative to the connector body 10, wherein the rod 6 is in the initial position 6A ( Figure 2 When the other connector 11 approaches the connector body 10, the rod 6 is rotated to position 6B after rotation is completed. Figure 3 As shown), the other connector 11 and the connector body 10 are thus fitted together. The connector body 10 and the rod 6 constitute the rod connector 1.

[0024] In this embodiment, arrows X, Y, and Z are set as mutually orthogonal directions. The mating direction of the rod connector 1 and the counterpart connector 11 is set as the Y direction (denoted as the front-back direction Y), the rotation axis direction of the rod 6 is set as the Z direction (denoted as the up-down direction Z), and the direction orthogonal to the Y and Z directions is set as the X direction (denoted as the left-right direction X). Sometimes, the Y1 direction (the side of the counterpart connector 11 of the rod connector 1) in the front-back direction Y is denoted as "front", and the opposite Y2 direction is denoted as "rear". In addition, sometimes the Z1 direction (the side of the first arm plate 61A) in the up-down direction Z is denoted as "up", and the Z2 direction (the side of the second arm plate 61B) is denoted as "down".

[0025] like Figures 4-6 As shown, the counterpart connector 11 has a counterpart terminal 12 ( Figure 6 (A) shown) and the counterpart housing 13 that houses the counterpart terminal 12.

[0026] like Figure 6 As shown, the outer casing 13 is, for example, made of resin components and formed into a square tube shape with the Y direction as its extending direction (axial direction of the tube). Figure 6 As shown, the counterpart housing 13 is configured to have: a counterpart wall portion 131 along the XZ plane; and a cover portion 132 for continuous engagement with the counterpart wall portion 131 to fit the rod connector 1.

[0027] like Figure 4 , Figure 5 As shown, in the cover 132, the connector port 13A for the rod connector 1 (described later) to be inserted is an end face along the XZ plane, and is configured to abut against the contact surface 620 of the rod 6 (described later) when the rod connector 1 reaches the rotation completion position 6B.

[0028] like Figure 6 As shown, guide protrusions and engaging protrusions 133 (not shown) are provided on the opposite upper wall 132A along the XY plane in the cover portion 132. The guide protrusions protrude downward Z2 from the opposite upper wall 132A and is guided into the cam groove 64 of the rod 6 in the rod connector 1 (described later).

[0029] The engaging protrusion 133 protrudes downwards towards Z2 and engages with the locking protrusion 66C of the rod connector 1 when the rod connector 1 reaches the rotation completion position 6B and the rod connector 1 is engaged with the counterpart connector 11.

[0030] Figures 1-3 The rod connector 1 shown includes: a connector body 10 having a plurality of female terminals 2 ( Figure 1 As shown), an inner housing 3 (shell) housing the plurality of female terminals 2, a front protective cover 5 (retainer) housing the inner housing 3, etc.; a rod 6, which is axially supported on the inner housing 3, and in the initial position 6A ( Figure 2 (as shown) and the rotation completion position 6B where it engages with the other connector 11 (as shown) Figure 3 (as shown) rotates between; and cover 7, which routes the wires connected to the plurality of female terminals 2.

[0031] like Figure 1As shown, 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 locked to the female terminals 2; and a front protective cover 5 that has a temporary locking receiving portion 57 and a formal locking receiving portion 58, which are locked to the locking arm 65 of the rod 6 described later.

[0032] like Figure 1 As shown, the female terminal 2 is housed in the terminal housing chamber 30A of the inner housing 3, which is connected to the end of the wire (not shown). The wire connected to the female terminal 2 is led out from each terminal housing chamber 30A to the rear Y2, inserted into the wire insertion port 7a of the cover 7, which is described later, and led out to the left-right X side.

[0033] The inner shell 3 is made of insulating synthetic resin. For example... Figure 1 , Figure 6 As shown in (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, and left and right side surfaces 3E and 3F that are continuous with the upper and lower surfaces 3A and 3B; a plurality of terminal receiving chambers 30A; and a spacer receiving chamber 30B. Figure 6 As shown in (A). Rotating shafts 31 for axial support of rod 6 are respectively provided on the upper surface 3A and the lower surface 3B. A spacer opening 30C for insertion of the spacer 4 (described later) is formed on the lower surface 3B. Figure 6 As shown in (A). On the left and right sides 3E and 3F, there are: a cover locking receiving part 33 that locks with the housing locking part 71 of the cover 7 (described later) and a protective cover locking receiving part 34 that locks with the housing locking part 59 of the front protective cover 5 (described later).

[0034] Multiple terminal receiving chambers 30A are arranged in the vertical direction Z and the horizontal direction X. Each terminal receiving chamber 30A is formed into a square tube shape with the Y direction as the extending direction (axial direction of the tube), and houses each female terminal 2.

[0035] like Figure 6 As shown in (A), each terminal receiving chamber 30A has openings at the front Y1 and the rear Y2. The opening at the front Y1 (hereinafter, sometimes referred to as the front side opening 30f) allows the counterpart terminal 12 of the counterpart connector 11 to be inserted into the terminal receiving chamber 30A, and the wire connected to the female terminal 2 is led out from the opening at the rear Y2 (hereinafter, sometimes referred to as the rear side opening 30b). In addition, a terminal spear-shaped member (not shown) that engages with the female terminal 2 is provided on the inner surface of each terminal receiving chamber 30A. The female terminal 2 is doubly engaged by the terminal spear-shaped member and the spacer 4 described later, thereby preventing the female terminal 2 from disengaging from each terminal receiving chamber 30A.

[0036] like Figure 6As shown in (A), the spacer housing 30B is part of the terminal housing 30A and houses the spacer 4, which will be described later.

[0037] Rotating shafts 31 are respectively provided on the upper surface 3A and the lower surface 3B, and are configured to provide shaft support for the rod 6 by means of bearing portions 63A and 63B inserted into the rod 6 described later.

[0038] like Figure 6 As shown in (A), the spacer 4 is received in the spacer receiving 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 configured to be movable 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 its respective terminal receiving chamber 30A, causing each female terminal 2 to engage with the spear-shaped member, thereby locking each female terminal 2 for the first time. By moving the spacer 4 from the temporary locking position to the permanent locking position, each female terminal 2 engages with the spacer 4 for the second time and is locked.

[0039] The front protective cover 5 is made of insulating synthetic resin. For example... Figure 1 As shown, the front protective cover 5 is box-shaped and includes: an upper wall 51 and a lower wall 52 along the XY plane; a front wall 53 and left and right side walls 54 and 55 that are continuous with the upper and lower walls 51 and 52; and a receiving opening 55 that receives the inner housing 3. The front protective cover 5 also includes: a first exposed opening 56A that exposes the end side of the rod 6 (described later); a temporary locking receiving part 57 that is disposed around the periphery of the first exposed opening 56A and engages with the locking arm 65 disposed on the rod 6 in the initial position 6A; a permanent locking receiving part 58 that engages with the locking arm 65 in the rotation completed position 6B; and a second exposed opening 56B that exposes the locking structure 66 disposed on the rod 6.

[0040] A connecting hole 530 is provided on the front wall 53 at a position where it communicates with the front side opening 30f of each terminal receiving chamber 30A in the inner housing 3. A housing locking part 59 is provided on the left and right side walls 54, 54, which locks into the protective cover locking receiving part 34 of the inner housing 3.

[0041] The first exposed opening 56A is formed by cutting into the upper wall 51 and the front wall 53, thereby exposing the inlet of the cam groove 64 of the rod 6 (described later) and the locking arm 65. A temporary locking receiving part 57 is provided around the periphery of the first exposed opening 56A to lock the locking arm 65 of the rod 6.

[0042] The temporary locking bearing part 57 is located at a position Y2 further back than the front end of the front protective cover 5, and is configured to include a plane including the left-right direction X and the up-down direction Z.

[0043] The formal locking bearing part 58 is located at one end and the rear end of the front protective cover 5 in the left-right direction X, and is provided at the periphery of the rectangular opening that allows the locking arm 65 of the rod 6 (described later) to be exposed.

[0044] The second exposed opening 56B is provided on the other end side in the left-right direction X (opposite to the formal locking bearing part 58, separated from the first exposed opening 56A), and is constructed by cutting the upper wall 51 and the front wall 53, and is configured to extend rearward X2 in such a way that the locking structure 66 of the rod 6 described later is exposed.

[0045] Rod 6 is made of insulating synthetic resin. For example... Figure 1 As shown, the rod 6 is configured as a gate (C-shaped) and includes: 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 arranged opposite each other and clamp the inner housing 3 between them; and a connecting part 62, which connects the first arm plate 61A and the second arm plate 61B.

[0046] The first arm plate 61A 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 protective cover 5) and is formed into a plate shape.

[0047] The first arm plate 61A is provided with: a bearing part 63A that engages with the rotation shaft 31 of the inner housing 3, a cam groove 64 through which the guide protrusion of the other connector 11 is inserted, a locking arm 65 that is locked to the front protective cover 5, and a locking structure 66 that engages with the engaging protrusion 133 of the other connector 11.

[0048] The first bearing portion 63A is formed as a through hole, through which the rotation shaft 31 of the inner housing 3 is inserted. Thus, the rod 6 is axially supported and can rotate relative to the inner housing 3 about the rotation shaft 31 and the bearing portion 63A (63B). Alternatively, the bearing portion 63A may not be a through hole, or it may be formed as a concave shape 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 rotation shaft 31 of the inner housing 3 may be formed as a through hole or a concave shape.

[0049] The cam groove 64 is configured such that the first arm plate 61A is formed into a slit with a concave cross section for the guide protrusion of the opposite connector to pass through, and has a shape (track) that allows the guide protrusion to approach the first bearing portion 63A when the rod 6 rotates.

[0050] like Figure 1 , Figure 2As shown, a locking arm 65 is disposed at the end of the first arm plate 61A away from the connecting portion 62. The locking arm 65 is configured to have: a cantilever beam-shaped arm 65A that can flex in the vertical direction Z; and a locking protrusion 65B that protrudes upward Z1 (on the side opposite to the second arm plate 61B) from the free end of the arm 65A.

[0051] like Figure 1 As shown, arm 65A is formed by forming a slit S in the first arm plate 61A. The slit S is formed by cutting an end edge of the first arm plate 61A away from the connecting portion 62, and extends in a straight line toward the connecting portion 62.

[0052] like Figure 2 , Figure 3 As shown, the locking structure 66 is provided at the end of the first arm plate 61A near the connecting portion 62, and is configured such that when the rod 6 is in the completed rotation position 6B, as... Figure 6 As shown, the connector body 10 and the other connector 11 are engaged by engaging with the engagement protrusion 133 of the other connector 11, thereby maintaining the mating state between the connector body 10 and the other connector 11.

[0053] like Figure 2 As shown, the locking structure 66 comprises: a lever arm 66B disposed between a pair of slits 66A, 66A of the first arm plate 61A; and a locking protrusion 66C disposed on the lever arm 66B and capable of engaging with the engaging protrusion 133 of the opposite connector 11. The pair of slits 66A, 66A are formed by cutting the rear end of the first arm plate 61A and extending it forward Y1 when the lever 6 is in the rotated position 6B. The locking protrusion 66C is disposed between the pair of slits 66A, 66A and protrudes upward Z1 from the middle of the front-rear direction Y.

[0054] like Figure 1 As shown, a second bearing portion 63B is provided on the second arm plate 61B, which engages with the rotation shaft 31 of the inner housing 3.

[0055] like Figure 3 , Figure 5 As shown, the connecting part 62 includes an abutment surface 620 (opposing surface) that can abut against the connector opening 13A of the other connector 11 when the rod 6 is in the rotated completed position 6B, and an operation part 621 located opposite to the abutment surface 620, and is configured as a plate with the long side direction of the direction opposite to the first arm plate 61A and the second arm plate 61B (vertical direction Z).

[0056] The root portion 62A of the first arm plate 61A (sometimes referred to as "one root") is continuously provided at one end of the abutment surface 620, and the root portion 62B of the second arm plate 61B (sometimes referred to as "another root") is continuously provided at the other end of the abutment surface 620. In addition, the abutment surface 620 extends away from the end of the abutment surface 62A, 62B of the pair of arm plates 61A, 61B.

[0057] Furthermore, the contact surface 620 is configured to have the following inclination: when the rod 6 is in the completed rotation position 6B, the root 62B of the second arm plate 61B is located further away from the counterpart connector 11 than the root 62A of the first arm plate 61A. Thus, as... Figure 4 As shown, even when the connector body 10 is engaged with the other connector 11, the position F of the operator pressing part 621 of the lever 6 near the root 62B of the second arm plate 61B can prevent the root 62B of the second arm plate 61B from abutting against the connector port 13A of the other connector 11 before the locking protrusion 66C of the lever 6 engages with the engaging protrusion 133 of the other connector 11.

[0058] The cover 7 is made of insulating synthetic resin. For example... Figure 1 , Figure 2 As shown, the cover 7 includes: a cover body 70 having an electrical wire insertion port 7a and an installation port 7b relative to the inner housing 3, and covering the rear Y2 surface of the inner housing 3; and a housing locking portion 71 disposed on the cover body 70 and locking with the cover locking receiving portion 33 of the inner housing 3.

[0059] Next, the assembly sequence of rod connector 1 will be explained.

[0060] First, the inner housing 3 is brought close to the first arm plate 61A and the second arm plate 61B of the rod 6, and the inner housing 3 is clamped by the first arm plate 61A and the second arm plate 61B. Thus, the bearing portions 63A and 63B are axially supported on each of the rotation shafts 31, and the rod 6 is axially supported on the inner housing 3 in a rotatable manner. In this way, the inner housing 3 with the rod 6 is assembled.

[0061] Next, the inner housing 3 with rod 6 is brought close to and inserted into the receiving opening 55 of the front protective cover 5. As a result, the front openings 30f of each terminal receiving chamber 30A in the inner housing 3 communicate with the communicating holes 530, and the protective cover retaining portion 34 of the inner housing 3 is engaged with the housing retaining portion 59 of the front protective cover 5. Furthermore, the rod 6 is in the rotation completion position 6B where the retaining protrusion 65B is engaged with the formal retaining portion 58 of the front protective cover 5. Thus, the inner housing 3 with rod 6 is received within the front protective cover 5.

[0062] Then, the spacer 4 is positioned in the temporary locking position of the inner housing 3, and the female terminal 2, which is connected to the wire, is inserted from the rear side opening 30b towards the front Y1 into the terminal receiving chamber 30A of the inner housing 3. Thus, the female terminal 2 is locked to the terminal spear-shaped member. Afterward, the spacer 4 moves from the temporary locking position to the permanent locking position. Thus, each female terminal 2 is doubly locked by the terminal spear-shaped member and the spacer 4, thereby preventing the female terminal 2 from disengaging from each terminal receiving chamber 30A. At this time, the wire connected to the female terminal 2 is led out from the inner housing 3.

[0063] Next, the mounting opening 7b of the cover 7 is brought close to the inner housing 3 of the rod 6, and the wire leading from the inner housing 3 is inserted into the wire insertion opening 7a of the cover 7. As a result, the cover locking support 33 is locked by the housing locking part 71. Thus, the cover 7 is assembled into the inner housing 3 of the rod 6. At this time, the wire leading from the inner housing 3 is led out to the left-right direction X.

[0064] Then, the lever 6 is rotated from the completed rotation position 6B to the initial position 6A. The locking arm 65 of the lever 6 is released from the locking bearing part 58 in the front protective cover 5, and the lever 6 becomes rotatable, allowing for further rotation, as... Figure 2 As shown, the locking arm 65 is engaged with the temporary locking support 57 of the front protective cover 5. In this state, the locking arm 65 is engaged with the temporary locking support 57, thereby maintaining the rod 6 in the initial position 6A where the rotation is restricted. Thus, the rod 6 is positioned in the initial position 6A, and the assembly of the rod connector 1 is completed.

[0065] Next, with the connector body 10 of the rod connector 1 engaged with the counterpart connector 11, and the rod 6 of the rod connector 1 in the initial position 6A, the connector body 10 is inserted close to the cover 132 of the counterpart connector 11. As a result, the guide protrusion of the counterpart connector 11 is inserted into the cam groove 64 of the rod 6, and the guide protrusion is positioned near the entrance of the cam groove 64.

[0066] Next, press the operating part 621 of the lever 6 to rotate the lever 6. During pressing (rotation), the lever connector 1 moves from its initial position 6A. When pressed, the locking protrusion 66C of the locking structure 66 abuts against the engaging protrusion 133 of the opposite connector 11, and the lever arm 66B of the locking structure 66 flexes downwards Z2, pressing the locking protrusion 66C downwards Z2 towards the engaging protrusion 133. As the pressing continues, the locking protrusion 66C passes over the engaging protrusion 133. When the locking protrusion 66C passes over the engaging protrusion 133, the lever arm 66B elastically returns to its original shape. By positioning the locking protrusion 66C on the Y1 side in front of the engaging protrusion 133, the locking protrusion 66C engages with the engaging protrusion 133. Figure 6(As shown in (A) and (B)). Approximately simultaneously, the guide protrusion is located at the inner end of the cam groove 64, the rod 6 reaches the locking arm 65 and locks into the rotation completion position 6B of the formal locking bearing 58, and the connector body 10 and the counterpart connector 11 are engaged. The engagement state of the connector body 10 and the counterpart connector 11 is maintained by engaging the locking protrusion 66C with the engaging protrusion 133.

[0067] Here, when the operator presses the operating part 621 of the lever 6 to rotate the lever 6, thereby engaging the connector body 10 with the other connector 11, as... Figure 4 As shown, even at position F near the root 62B of the second arm plate 61B in the operation section 621 of the pressing rod 6, the abutment surface 620 is configured such that the root 62B of the second arm plate 61B is located at a position farther from the connector port 13A of the counterpart connector 11 than the root 62A of the first arm plate 61A. As a result, the operation section 621 is pressed in along the inclination of the abutment surface 620 to approach the connector port 13A of the counterpart connector 11.

[0068] Therefore, the locking protrusion 66C of the lever 6 can engage with the engaging protrusion 133 of the opposite connector 11 before the root 62B of the second arm plate 61B in the abutment surface 620 interferes with the connector opening 13A of the opposite connector 11. In other words, the lever 6 can prevent the root 62B of the second arm plate 61B from interfering with the connector port 13A of the opposite connector 11 before the locking protrusion 66C of the lever 6 engages with the engaging protrusion 133 of the opposite connector 11.

[0069] Therefore, the locking protrusion 66C of the lever 6 reliably engages with the engaging protrusion 133 of the counterpart connector 11, thus ensuring a secure engagement state that maintains the mating state between the connector body 10 and the counterpart connector 11. In this way, the abutment surface 620 is configured such that the root 62B of the second arm plate 61B is located at a position further away from the counterpart connector 11 than the root 62A of the first arm plate 61A, thereby improving the efficiency of the connector mating operation and suppressing adverse conditions related to the mating of the counterpart connector 11.
