Description

  The present invention relates to an electrical connector provided with a lever that assists in fitting with a mating connector.

In recent years, electrical connectors used in the field of automobiles have become increasingly multipolar, and electrical connectors formed in multiple poles require a large force when mating and unmating the connectors. For this reason, a lever-type connector that assists in mating and unmating with the mating connector using the boosting effect of the lever is used (for example, Patent Document 1). The lever-type connector has a lever supported by a connector housing fitted with a mating connector. A typical lever is a U-shaped member having a pair of lever bodies and a connecting portion that connects the lever bodies to each other.
The lever-type connector is fitted to the mating connector by rotating the lever from the fitting start position to the fitting completion position. Before fitting with the mating connector, the terminal to which the electric wire is connected is inserted into each cavity formed in the connector housing. At that time, among the fitting start position and the fitting completion position, the lever (particularly the connecting portion) is placed and inserted so that the insertion of the terminal is not hindered.

JP 2005-317384 A

In addition to the miniaturization of the connector itself, the space allowed around it has become smaller year by year. This is because, for example, when another device is in the vicinity of the connector, or when the connector is fitted in a state of being close to each other with respect to a plurality of connector housings (fitting gaps) of the mating connector. This becomes prominent when close to the connector. The lever-type connector of Patent Document 1 is employed when the lever in the fitting completion position protrudes largely around the connector housing, so that the space occupied by the connector is large and equipment or other connectors are close to each other. Have difficulty. In order to reduce the occupied space, it is necessary to determine the fitting start position and the fitting completion position of the lever so that the lever does not protrude around the connector housing. In this case, however, the lever, particularly the connecting portion, may cover a part of the terminal insertion surface in which an opening leading to the cavity is formed. Then, the lever prevents the terminal from being inserted into the cavity.
The present invention has been made based on such a problem, and an object of the present invention is to provide a lever-type connector that can suppress a space occupied by the lever without hindering insertion of a terminal.

The lever-type connector of the present invention made for such a purpose includes a connector housing that holds a plurality of terminals to which electric wires are respectively connected, and is pivotally supported by the connector housing, and is fitted from a fitting start position to a fitting completion position. And a lever that is fitted in the mating connector by being rotated in the range of the matching angle.
The connector housing includes a plurality of cavities that respectively hold the terminals.
The lever is rotatable to the terminal insertion position outside the fitting angle range.
The lever at the fitting start position is on an extension of at least a part of the axes of the plurality of cavities, is located on the opening side where the terminal is inserted in the cavity, and the lever at the terminal insertion position is It is retracted from the axis of multiple cavities.

In general, a connector is fitted with a mating connector after a terminal insertion operation for holding the terminal in the connector housing. This terminal insertion operation is performed in a state in which the connector is separated from the mating connector (distant location). That is, before the fitting operation, the lever may protrude greatly from the connector housing.
Therefore, in the present invention, a terminal insertion position different from the fitting start position and the fitting completion position related to the fitting work is provided as the lever position. As described above, since the terminal insertion work is performed in a state of being separated from the mating connector, the terminal insertion position is such that the lever protrudes from the connector housing and interferes with the adjacent connector and surrounding members during the fitting work. Can be provided at any position. Therefore, if the terminal insertion position is set so that the lever does not cover the terminal insertion surface, the lever does not hinder the insertion of the terminal.
When the terminal insertion work is completed, the fitting work is performed after rotating the lever to the fitting start position. By setting the fitting start position and the fitting completion position so that the lever does not protrude around the connector housing, the space occupied by the lever-type connector can be suppressed.
As described above, the space occupied by the lever can be suppressed without hindering insertion of the terminal.
The connector housing in the present invention includes a wire cover.

In the lever-type connector of the present invention, it is preferable that the terminal insertion position, the fitting start position, and the fitting completion position are arranged in this order.
By doing so, the lever can be rotated in one direction through the terminal insertion operation and the fitting operation, so that the operability of the lever is excellent.

The lever-type connector of the present invention, the connector housing comprises a plurality of cavities for holding terminals, respectively, the lever in the terminal insertion position, it is retracted from the axis of the plurality of cavities.
According to the present invention, when trying to insert a terminal into the cavity along the axis of each cavity, the lever does not hinder the insertion, so that the terminal can be reliably inserted.
Furthermore, the lever-type connector of the present invention is fitted to the mating connector in a state adjacent to another lever-type connector, and the lever at the fitting start position is an extension of at least a part of the axes of the plurality of cavities. And it is preferable that it is located in the side of the opening in which the terminal in the said cavity is inserted.

  The present invention newly provides a terminal insertion position different from the fitting start position and the fitting completion position related to the fitting of the connector, thereby suppressing the space occupied by the lever without hindering the insertion of the terminal. be able to.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
The connector 10 of this embodiment shown in FIGS. 1 to 5 is a lever-type connector that is fitted and released from the mating connector housing 81 by operating the lever 60. As shown in FIG. 1, the connector housing of the connector 10 is fitted into each of two mating connector housings 81 provided side by side on the base 100 of the mating connector 80. At this time, the levers 60 of the adjacent connectors 10 are arranged 180 degrees symmetrically with the boundary portion 101 of the mating connector housings 81 and 81 interposed therebetween.
Hereinafter, in the connector 10, the side mated with the mating connector is defined as “front” and the opposite side is defined as “rear”.

<Overall configuration>
The connector 10 includes a substantially rectangular parallelepiped inner housing 20 that holds contacts (terminals) (not shown), a front housing 30 disposed on the front end side of the inner housing 20, and an outer housing 40 disposed around the inner housing 20. And a wire cover 50 disposed on the rear side of the inner housing 20. These members constitute the connector housing of the connector 10 and can be formed by injection molding a resin having insulating properties.
Further, the connector 10 includes a wire seal 70 and a seal ring 75, thereby preventing water from entering from the outside.

<Inner housing 20>
The inner housing 20 is provided with a plurality of cavities 21 that penetrate the inner housing 20 in the front-rear direction and accommodate contacts, and a receiving groove 22 that receives the mating connector housing 81.
Further, the inner housing 20 is provided with a peripheral wall 23 extending rearward at the peripheral edge of the rear end facing the outer housing 40, and a seal receiving recess (not shown) in which the inner side of the peripheral wall 23 stores the wire seal 70. (Omitted).

  Furthermore, the inner housing 20 includes a retainer receiving recess 26 into which a retainer 25 manufactured independently of the inner housing 20 is inserted. The retainer receiving recess 26 opens to the side surface of the inner housing 20, and the retainer 25 is retracted to a position where interference with the contact is avoided until the retainer 25 is inserted through the opening and the contact is inserted into the cavity 21. After the contact is inserted, when the retainer 25 is inserted all the way into the retainer receiving recess 26, it interferes with the contact and prevents the contact from being removed from the inner housing 20.

  Such an inner housing 20 includes a columnar fulcrum shaft 27 protruding from the outer peripheral surface 24. The fulcrum shaft 27 is coaxially provided on both sides in the direction crossing the outer peripheral surface 24. With the fulcrum shaft 27 as the center of rotation, the lever 60 is rotated from a fitting start position, which will be described later, toward the fitting completion position, whereby the mating with the mating connector housing 81 is performed. When the lever 60 is rotated from the position toward the mating start position, the mating with the mating connector housing 81 is released.

  The inner housing 20 includes a lock piece 28 and a lock hole 29 on both sides of the outer peripheral surface 24 in the direction orthogonal to the transverse direction. By inserting the lock piece 28 into the lock hole 461 of the outer housing 40, the inner housing 20 and the outer housing 40 are fixed to each other. The inner housing 20 and the front housing 30 are fixed to each other by inserting the lock piece 33 of the front housing 30 into the lock hole 29.

<Front housing 30>
The front housing 30 is formed with a guide port 31 which is formed in a tapered shape and guides the contact of the mating connector housing 81 to the cavity 21 of the inner housing 20.
Note that the front housing 30 is added to the inner housing 20 because the connector 10 of the present embodiment is small and it is difficult to create the guide port 31 at the end of the cavity 21. Such a front housing 30 should just be provided as needed.

<Outer housing 40>
The outer housing 40 includes a seal pressing block 41 and a pair of regulating walls 42 and 42 that face each other outside the seal pressing block 41 and prevent the lever 60 from falling off the inner housing 20 during rotation. .

  The seal pressing block 41 includes a substantially rectangular plate-shaped pressing portion 410 that presses the plate-shaped wire seal 70 toward the inner housing 20 when the inner housing 20 and the outer housing 40 are assembled to each other. By being pressed by the pressing portion 410 in this way, the outer peripheral portion 71 of the wire seal 70 is in close contact with the inner peripheral portion of the seal housing recess, and the inner wall of the contact insertion hole 72 formed in the wire seal 70 is used as a contact. It closely adheres to the outer periphery of each connected electric wire 2 (wire). This prevents water from entering the inner housing 20.

  In the pressing portion 410, a plurality of contact insertion holes 44 are formed coaxially with the cavities 21. The electric wire 2 connected to each contact extends through the contact insertion hole 72 of the wire seal 70 and the contact insertion hole 44 of the pressing portion 410 toward the wire cover 50 behind the seal pressing block 41. ing. Here, the electric wire 2 is inserted from the contact insertion hole 44 toward the cavity 21. Therefore, the surface on the rear end side of the pressing portion 410 is a terminal insertion surface 410A into which the connector is inserted.

The seal pressing block 41 includes guides 45a, 45b, 45c, and 45d that rise rearward from the respective corners of the pressing portion 410. Each of the guides 45a to 45d has an L-shaped cross section. The wire cover 50 is attached to the outer housing 40 in a state of being disposed in a region surrounded by the four guides 45a to 45d.
Holding walls 46 and 46 are configured by connecting guides 45a and 45b and guides 45c and 45d adjacent to each other in the width direction of the pressing portion 410, respectively. Each holding wall 46 is formed with a lock hole 461 into which the lock piece 28 of the inner housing 20 is inserted. In addition, a lock hole 462 into which the lock protrusion 53 of the wire cover 50 is inserted is formed in one holding wall 46, and a guide hole (in which the guide piece 54 of the wire cover 50 is inserted is formed in the other holding wall 46. (Not shown) is formed.

The restricting walls 42 are provided on both sides of the seal pressing block 41 in the width direction. These restricting walls 42 and 42 cover substantially the entire area of both side surfaces of the seal pressing block 41 except for the guides 45a, 45b, 45c and 45d. A gap 48 for rotating the lever 60 within a predetermined operating angle range is provided between both side surfaces of the seal pressing block 41 and the regulation walls 42 and 42.
Further, both ends of the regulation walls 42, 42 in the longitudinal direction are connected to the seal pressing block 41 via connection walls 47a, 47b.
Such an outer housing 40 is disposed in front of the pressing portion 410, and the accommodating chamber 49 is surrounded by the regulating walls 42 and 42, the holding walls 46 and 46, and the connection walls 47a and 47b of the regulating walls 42 and 42, respectively. have. The accommodation chamber 49 accommodates the inner housing 20 and the rear end portion of the front housing 30.

<Wire cover 50>
The wire cover 50 covers the plurality of electric wires 2 that are respectively connected to contacts accommodated and held in the inner housing 20. The plurality of electric wires 2 are drawn out toward a lead-out port 52 provided at one end of the wire cover 50 and further drawn out to the outside.
The wire cover 50 is provided with a lock protrusion 53 and a guide piece 54. When the wire cover 50 is attached to the outer housing 40, the guide piece 54 and the guide hole of the outer housing 40 serve as a guide, and the lock protrusion 53 is inserted into the lock hole 462 of the outer housing 40. 50 and the outer housing 40 are fixed to each other.

Further, on the opposite side of the wire cover 50 from the outlet 52, there are a start position stopper 55 to which one side 601 of the lever body 61 is abutted, and a recess (not shown) formed in the back surface 611 of the lever body 61. A lock projection 57 to be inserted is provided. The start position stoppers 55 are provided on both sides of the wire cover 50 in the width direction. The lock protrusion 57 restricts the rotation of the lever 60 at the fitting start position toward the fitting completion position. The start position stopper 55 and the lock projection 57 define the fitting start position of the lever 60.
On the other hand, on the drawing port 52 side of the wire cover 50, a completion position stopper 58 to which the end of the connecting portion 62 of the lever 60 is abutted, and a lock member 56 that locks the connecting portion 62 of the lever 60 at the fitting completion position. And project. The lock member 56 restricts the rotation of the lever 60 in the fitting completion position toward the fitting start position. A fitting completion position is defined by the lock member 56 and the completion position stopper 58.

<Lever 60>
The lever 60 extends from the base end 61a to the tip end 61b, has a lever body 61 facing each other, and a connecting portion 62 that connects the tip ends 61b of the lever body 61, and is formed in a substantially U shape.
Near the base end 61a of the lever body 61, a fulcrum hole 63 into which the fulcrum shaft 27 of the inner housing 20 is inserted is formed. A guide groove 64 for guiding the fulcrum shaft 27 to the fulcrum hole 63 is formed on the back surface 611 of the lever main body 61 so as to communicate with the fulcrum hole 63.
A cam groove 65 is formed on the back surface 611 of the lever body 61 closer to the base end 61 a than the fulcrum hole 63. The mating connector housing 81 is provided with a cam pin (not shown) guided along the cam groove 65. When the lever 60 is rotated, the connector is directed toward the mating connector housing 81 by the action of the cam groove 65 and the cam pin. 10 is pushed.

  On the back surface of the connecting portion 62, a locked portion 66 that protrudes when the thickness of the other portion is reduced is formed. When the lever 60 is tilted until the end of the connecting portion 62 is abutted against the completion position stopper 58, the locked portion 66 gets over the lock member 56 of the wire cover 50, and thereby the fitting start position side of the lever 60 is reached. Rotation to is restricted.

  The lever 60 is engaged with the connector 10 and the mating connector housing 81 by being rotated from the fitting start position to the fitting completion position. 3, 4, and 5 show the connector 10 when the lever 60 is in the mating start position, in the mating completion position, and in the terminal insertion position, respectively. 3 and 4, illustration of the wire cover 50 is omitted, and in each of FIGS. 3 to 5, the wire 2 connected to the contact is omitted. Is omitted.

When the lever 60 is in the fitting start position, the connecting portion 62 faces the terminal insertion surface 410A of the outer housing 40 from the rear, and covers a part of the terminal insertion surface 410A (FIG. 3).
On the other hand, when the lever 60 is in the fitting completion position, the connecting portion 62 does not face the terminal insertion surface 410A of the outer housing 40, and there is nothing that blocks the terminal insertion surface 410A (FIG. 4).

As shown in FIG. 5, the rotation angle from the fitting start position Pst to the fitting completion position Pfn is the fitting angle of the lever 60 when the connector 10 and the mating connector housing 81 are fitted or released. Within the range Rco, the lever 60 is rotatable to the terminal insertion position Pin located on the fitting start position Pst side with respect to the fitting angle range Rco. That is, the operation angle range Rro of the lever 60 is from the terminal insertion position Pin to the fitting completion position Pfn.
The three positions of the lever 60 are arranged in the order of the terminal insertion position Pin, the fitting start position Pst, and the fitting completion position Pfn in the counterclockwise direction in FIG.
The terminal insertion position Pin is defined by the side surface 601 of the lever 60 being abutted against the connection wall 47a.

  At the terminal insertion position Pin, the contact to which the electric wire 2 is connected is inserted from the contact insertion hole 44 opened on the terminal insertion surface 410A. At this time, the lever 60 is rotated to a position substantially parallel to the terminal insertion surface 410A, and the connecting portion 62 is disposed outside the holding wall 46 of the outer housing 40. Some of them are not covered with the connecting portion 62. The electric wire 2 connected to the contact held in the cavity 21 is drawn out from the terminal insertion position Pin side forming one end of the operation angle range Rro toward the fitting completion position Pfn on the other end side.

<Wire seal 70>
The wire seal 70 is usually made of elastomer (Elastic Polymer), but the material is not limited as long as it is a material that can exhibit a waterproof function. In the wire seal 70, a plurality of contact insertion holes 72 are formed coaxially with the cavity 21, respectively.

<Seal ring 75>
The seal ring 75 is disposed inside the receiving groove 22 of the inner housing 20 and stops water between the outer wall of the mating connector housing 81 and the inner wall of the receiving groove. Further, the seal ring 75 is pressed between the front end of the inner housing 20 and the rear end of the front housing 30 by inserting the lock piece 33 of the front housing 30 into the lock hole 29 of the inner housing 20. And the front housing 30 are also stopped.

Next, an operation of inserting a contact (terminal) into the cavity 21 of the connector 10 whose configuration has been described above and assembling the contact and the electric wire 2 to the connector 10 will be described.
As shown in FIG. 6A, in a state where the lever 60 is disposed at the terminal insertion position, the contact is inserted into the cavity 21 from the contact insertion hole 44 opened in the terminal insertion surface 410A and held. At this time, since the terminal insertion surface 410A is widely open to the outside without being covered with the connecting portion 62, the contact can be easily inserted. When the retainer 25 is pushed from the outside of the outer housing 40 after inserting the contact into each cavity 21, the contact is locked to the retainer 25.
Next, after directing the electric wire 2 connected to each contact toward the mating completion position, the lever 60 is temporarily moved to the inverted position past the mating start position as shown in FIG. By rotating counterclockwise, the wire cover 50 is inserted between the connecting portion 62 and the lever main bodies 61 and 61 and attached to the outer housing 40. This is because if the wire cover 50 is mounted while the lever 60 is in the terminal insertion position, the start position stopper 55 is obstructed and the lever 60 cannot be rotated to the fitting start position. Then, as shown in FIG. 6C, when the side surface 601 of the lever main body 61 is rotated clockwise until it abuts against the start position stopper 55, the lever 60 reaches the fitting start position and the back surface 611 of the lever 60. By inserting the lock convex portion 57 into the concave portion, the lever 60 is disposed at the fitting start position.

When the assembly work of the contact and the electric wire 2 is completed as described above, the process proceeds to the assembly work with the mating connector 80. The operations up to this point can be performed at a location away from the mating connector 80.
When the connector 10 is fitted to the mating connector 80, the mating connector cam pin is inserted into the cam groove 65 of the lever 60 by abutting the mating surfaces of the connector 10 and the mating connector housing 81.
Subsequently, when the lever 60 is rotated from the fitting start position toward the fitting completion position, the connector 10 is pushed into the mating connector housing 81 by the action of the cam groove 65 and the cam pin. If the lever 60 is rotated as it is until the end of the connecting portion 62 hits the completion position stopper 58, the locked portion 66 of the connecting portion 62 gets over the lock member 56, and the lever 60 reaches the fitting completion position. An electrical connector is configured by performing the fitting and assembling work of the connector 10 as described above to each of the mating connector housings 81 arranged on the base 100.

Here, a typical lever-type connector has two positions, a fitting start position and a fitting completion position, as lever locking positions, and is rotatable between these two positions. .
Then, in the configuration in which the two connectors 10 and 10 are arranged close to each other as shown in FIG. 1, the lever 60 starts to be fitted at a position beyond the start position stopper 55 so that the connecting portion 62 does not hinder terminal insertion. When the position is provided, the lever 60 interferes with the lever 60 of the adjacent connector 10 during the fitting. Further, when the lever 60 is tilted beyond the fitting completion position shown in FIG. 4 so as not to hinder terminal insertion, interference with the adjacent connector 10 can be avoided, but a space occupied by the lever 60 is necessary around it. become.

  Also, unlike FIG. 1, when a plurality of connectors 10 are arranged close to each other with the levers 60 in the same direction, workability is reduced. In other words, if the mating start position or mating completion position is set at a position where the terminal can be easily inserted, the lever 60 protrudes toward the adjacent connector 10 at the time of mating, so the connector disposed on one end side of the connector 10 row. In order from 10, the mating with the mating connector housing 81 must be performed, and workability is lowered in this respect.

  For the reasons described above, when there are only two locking positions of the lever 60, that is, the fitting start position and the fitting completion position, it is easy to insert the terminal, and the workability is improved. The occupied space cannot be reduced.

Here, since the terminal insertion work of the connector 10 is performed at a place away from the mating connector 80, the lever 60 may protrude largely outside the connector 10 before the fitting work.
Therefore, in the connector 10 of this embodiment, a terminal insertion position different from the fitting start position and the fitting completion position related to the fitting work is provided. Since the terminal insertion position is set so that the lever 60 (the connecting portion 62) does not cover the terminal insertion surface 410A, the lever 60 does not hinder insertion of the terminal.
When the terminal insertion work is finished, the lever 60 is rotated to the fitting start position and then the fitting work is performed. At the fitting start position, the connecting portion 62 faces the terminal insertion surface 410A, and at the fitting completion position, the connecting portion 62 faces the wire cover 50. That is, the lever 60 does not protrude around the connector 10 at the fitting start position and the fitting completion position.
As described above, the space occupied by the connector 10 can be suppressed without the lever 60 hindering the insertion of the terminal or the workability.

In this embodiment, as shown in the schematic diagram of FIG. 8A, the terminal insertion position Pin, the fitting start position Pst, and the fitting completion position Pfn are arranged in the counterclockwise order, and the electric wire 2 is Although it is pulled out from the terminal insertion position Pin side toward the fitting completion position Pfn side, the relationship between the terminal insertion position and the direction in which the electric wire is pulled out in the present invention is not limited to this, and it may be as shown in FIG. Good. In FIG. 8B, the fitting start position Pst, the fitting completion position Pfn, and the terminal insertion position Pin are arranged in the counterclockwise order, and the electric wire 2 is arranged from the terminal insertion position Pin side to the fitting start position Pst. It is pulled out toward the side.
8A and 8B, the lever position side (terminal insertion position Pin side) that forms one end of the operating angle range Rro to the other end side (FIG. 8A shows the fitting completion position Pfn side, 8 (B), since the electric wire 2 is drawn out toward the fitting start position Pst side), after completing the terminal insertion operation at the terminal insertion position, the electric wire 2 is pulled out in a predetermined direction and the lever 60 is fitted. When rotating toward the start position, the electric wire 2 and the connecting portion 62 of the lever 60 do not interfere with each other. That is, the lever 60 is preferable because it does not hinder the work of pulling out the electric wire 2 in a predetermined direction and the trouble of passing the electric wire 2 between the connecting portion 62 and the lever main bodies 61 and 61 does not occur. In particular, in the configuration of FIG. 8A, it is only necessary to rotate the lever 60 in one direction (counterclockwise) through the terminal insertion work and the fitting work, and the fitting from the terminal insertion position Pin as shown in FIG. Since it is not necessary to return the lever 60 that has been rotated to the fitting start position Pst via the fitting completion position Pfn to the fitting completion position Pfn, the operation of the lever 60 becomes smooth.

In addition to those described above, the configurations described in the above embodiments can be selected or modified as appropriate to other configurations without departing from the gist of the present invention.
The wire cover 50 of the above embodiment is provided with the start position stopper 55, but this is not essential. As shown in FIG. 7, the fitting start position can be defined only by the lock projection 57. In this configuration, the wire cover 50 is attached to the outer housing 40 when the lever 60 is in the terminal insertion position, and then the lever 60 is moved to the terminal insertion position without going through the inverted position of FIG. Directly to the fitting start position. This is because the start position stopper 55 that prevents the rotation of the lever 60 is not provided.

  The terminal insertion position is not limited to the position exemplified in the above embodiment, and is appropriately designed according to the specific structure of the lever-type connector. Although FIG. 5 shows the terminal insertion position where the lever 60 is substantially parallel to the terminal insertion surface 410A, a terminal insertion position where the lever 50 is raised closer to the fitting start position may be set. As in FIG. 5, as long as the lever 60 is retracted from the axis of each contact insertion hole 44 provided coaxially with the cavity 21, the contact is surely inserted into the cavity 21 along the axis of the contact insertion hole 44. Can be inserted.

  In the above embodiment, the connector 10 including the wire cover 50 is shown. However, the present invention is not limited to this, and the present invention can also be applied to a connector not including the wire cover. The shaft support portion of the lever and the lock portion for locking the lever may be provided in either the wire cover or the connector housing.
