DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector technology for a vehicle used in a narrow space such as an engine room of a vehicle, and more particularly, to a technology for drawing out a wiring connected to a connector in two different directions. The present invention relates to a technology that can be effectively used for a control device such as lock brake control in which wirings or pipes of different systems of hydraulic pressure and electricity (or electronic) coexist.

[0002]

BACKGROUND OF THE INVENTION An automobile requires driving means such as an engine for applying a rotational force to wheels and braking means for applying a braking force to wheels. The driving means and the braking means are controlled by electric / electronic control. Controlled. A control device for control involves a considerable number of wirings for receiving control signals and power input from outside. A connector is used to make an electrical connection to the control device through such wiring. One of the connectors is a male type and the other is a female type. The connector is composed of first and second connector members that are paired with each other, and the first connector member that is one of the two connector members is The second connector member, which is integrally supported on the housing side of the control device and forms a pair, is attached to and supported by the first connector member from outside the control device.

[0003] A control device for control is generally arranged in a narrow space such as an engine room or a trunk room. Therefore, in order to increase the degree of freedom in the layout of the device in relation to other devices such as an engine and a brake, it is effective to selectively extract wiring extending from the control device in two different directions. In order to realize the method, it is conceivable to devise a second connector member attached from the outside of the control device. That is, in order to bundle and bundle the wiring, the projecting piece provided at the outlet of the connector is provided not on the side of the block-shaped connector main body but on the side of the cover covering one surface of the connector main body. When a protruding piece is provided on the connector body side, the protruding piece limits the direction in which the wiring is drawn out in one direction. On the other hand, when the projecting piece is provided on one side of the cover having the wiring guide port, the wiring can be guided and drawn in two directions by selecting the direction of the wiring guide port.

[0004]

By the way, when a projecting piece is provided on the cover side, various studies have been made on the function of bundling and putting together wiring, and it has been found that the function is affected by the manner of attaching the cover to the connector body. . For example, if a cover is attached so as to cover over one surface of a block-shaped connector body where multiple wires stand up, all the wires are distributed inside the cover because the wires are distributed over the entire surface of the connector body. The work to put in is a little troublesome. When the cover is attached, not all of the wires are necessarily bundled together, and there is a possibility that some of the wires may come out of the cover. Therefore, it is necessary to assist a plurality of wires extending from the connector main body so as to be bundled with one hand.

The present invention has been made in view of the results of the above-described studies, and provides a connector technology which allows the wiring to be drawn out in two directions and allows the cover to be easily attached to the connector body. The purpose is to provide. Another object of the present invention is to provide a connector technology capable of naturally bundling a plurality of wirings with the attachment of a cover. Still other objects of the present invention will become apparent from the following description.

[0006]

An automotive connector according to the present invention has the following features in a second connector member attached from the outside of a control device. A cover has a wiring guide port on one side, and further, a protruding piece protruding from the main body portion of the cover on an upper portion of the cover on the side where the wiring guide port is provided, and by selecting the direction of the wiring guide port, The wiring can be guided and pulled out in two directions. The B cover can be attached to the connector body by sliding in a direction orthogonal to the direction connecting the fitting opening of the connector body and the wiring outlet.

Here, as means for attaching the cover to the connector body by sliding in a specific direction,
It is effective to provide guide grooves and / or rails on both sides of one surface of the connector body where the wiring outlets are arranged, and guide rails and / or grooves on both sides below the cover. The guide groove or rail preferably has an L-shaped cross section, and more preferably, a guide wall is provided so as to face the opening of the L-shaped groove, and the guide rail is formed by the grooved portion and the guide wall. It is good to pinch it. As a result, the cover can be more firmly attached to the connector main body, and the structure can be sufficiently resistant to vibrations and the like accompanying the traveling of the automobile.

Further, the projecting piece integral with the cover main body portion extends from the cover main body portion in the mounting direction of the cover, and collects wiring extending from the connector main body when the cover is mounted on the connector main body. To work. Therefore, it is preferable that the protruding piece has a shape in which the cross section is widened like a circular arc. Then, the wiring can be more securely bundled together with the attachment of the cover. Also. By providing a flange at the tip of the projecting piece, the projecting piece can be reinforced. The flange is a portion to which a finger is applied when attaching or detaching the cover, and also facilitates the work of attaching and detaching the cover.

The present invention can be widely applied as a connector technology for automobiles. In particular, wiring or piping of different systems of hydraulic and electric (or electronic) such as antilock brake control is used. It can be effectively used for control devices that coexist.

[0010]

1 and 2 show a control unit for controlling an antilock brake of an automobile to which the present invention is applied. The anti-lock brake control device generally includes a solenoid valve for filling and loosening, a hydraulic pump driven by a motor, etc., a fluid unit disposed between the master cylinder and the wheel cylinder, and an electronic circuit board. An electronic control unit for controlling the drive of the motor of the fluid unit and the opening and closing of the solenoid valve, and an input unit for supplying a control signal and power to the electronic control unit. The control unit 10 shown in the figure integrates a housing main body 24 of an electronic control unit 20 and an input section including an input connector member 30 with a pump housing 14 containing a plunger-type hydraulic pump driven by a motor 12. Attached.
Through such integration, it is possible to reduce the number of connecting portions of a harness, a connector, and the like, to reduce a mounting space of an automobile, to reduce an electrical connection portion, and to improve reliability (for example, Japanese Patent Application Laid-Open No. HEI 9-110572). 10-59152 and JP-A-11-297450).

The antilock brake control unit 10 has a male connector member 30 integrated with its housing, and the connector member (that is, the first connector member) 30 is a second connector member. The female connector members 50 fit together. The first and second connector members 30, 50 that fit into each other function as connectors for electrical connection.

The second connector member 50 has a block-shaped connector main body 55 and a cover 52 covering one surface of the connector main body 55. 3 to 5 are perspective views showing the second connector member 50 in three states. 3 shows a state in which the cover 52 is removed from the connector main body 55, FIG. 4 shows a state in which the cover 52 is put on the connector main body 55 by about half, and FIG. 5 shows a state in which the cover 52 is put on the connector main body 55 completely. It is in a state where it is. The main body of the cover 52 and the connector main body 55 is a resin molded product, and there are a plurality of electrical connection terminals inside the block-shaped connector main body 55, and the lower surface 55 b of the block is a fitting opening for the first connector member 30. Yes, opposite top surface 55
In a, a plurality of wiring outlets 60 for drawing out the respective wirings 100 extending from the internal connection terminals are arranged in a plurality of rows.

The connector body 55 having the wiring outlet 60
The two walls 70, 72 stand symmetrically on both sides of the upper surface 55a. Each of the walls 70 and 72 on both sides extends substantially entirely from one end to the other end in the longitudinal direction of the upper surface 55 a so as to surround the wiring outlet 60. Outer wall 7
0 has a guide groove 80 which is thicker than the inner wall 72 and extends in the longitudinal direction. The inner wall 72 has a guide groove 80.
The guide groove 80 has an L-shaped cross-section because it runs in parallel to face the opening. A well-known lock member having a handle 57 is fitted in the connector body 55. With the lock member pulled out from the connector main body 55, the connector main body 55 is fitted into the other connector member 30 of the pair, and then the lock member is inserted inside the connector main body 55, so that the connector member 30 and the connector member 50 can be locked.

Next, attention is paid to the cover 52. Cover 52
The main body portion 520 has a cap shape having an internal space enough to accommodate a bundle of wirings 100 extending from the wiring outlet 60. The main body portion 520 has side walls 520a and 520b on both sides in the longitudinal direction, and the side walls 520a and 520b.
The upper lid 520p, the inclined lid 520q, and the vertical lid 520r are sequentially integrated on the upper part of the upper part in the form indicated by the name. Therefore, the surface on the side opposite to the vertical lid 520r is a square opening. The opening is a portion serving as the wiring guide port 90. As can be seen from the figures, especially FIGS. 4 and 5,
The wiring guide port 90 is a port for pulling out and guiding the wiring 100 extending from the upper surface 55a of the connector main body 55 to the outside. Therefore, the wiring 100 can be selectively pulled out in two directions by selectively tilting the wiring 100 to the left or right and selecting the direction of the wiring guide opening 90 to the left or right.

Below the side walls 520a and 520b of the cover 52, there is a flange 530 that extends perpendicularly to the side walls 520a and 520b and extends outward. Each of the flanges 530 on both sides, together with a part of the side walls 520a and 520b, forms a guide rail having an L-shaped cross section. Each flange 530 extends from one end to the other end of the side walls 520a, 520b, but the end 530s on the side of the vertical lid 520r stands vertically like the vertical lid 520r. This end 530
When the cover 52 slides and attaches to the connector main body 55 side, it hits the ends of the side walls 520a and 520b, and prohibits the cover 52 from moving any further. That is, the end 530s functions as a stopper when the cover 52 is attached. The vertical lid 520r has a cutout groove 85 into which the inner wall 72 of the upper surface 55a of the connector main body 55 enters. The portion of the inner wall 72 that fits into and engages with the notch groove 85 and the portion of the side walls 520a, 520b that are sandwiched between the inner and outer walls 72, 70 limit movement in the direction along the upper surface 55a of the connector body 55, Moreover, the cover 5 that fits into the groove 80 of the outer wall 70
The flange 530 on the second side is connected to the upper surface 55 of the connector body 55.
Limit the movement in the direction perpendicular to a. The cover 52 is firmly supported by the connector main body 55 due to the restriction from both directions perpendicular to each other. Note that there is also a portion in the middle of the flange 530 that is unevenly coupled to the portion on the connector body 55 side.
Is prevented from coming off in the longitudinal direction.

Furthermore, the wiring guide port 90 of the cover 52
Looking at the portion, there is a protruding piece 200 protruding from the main body portion 520 of the cover 52 so that the upper lid 520p is extended. The protruding piece 200 is in a positional relationship parallel to the upper surface 55a of the connector main body 55 like the upper lid 520p.
The cross section of the illustrated protruding piece 200 has an arc shape. The arc-shaped projecting piece 200 fits the guide rail on the cover 52 side from one end of the guide groove on the connector main body 55 side, and attaches the cover 52 to the connector main body 55 as shown in FIGS.
When sequentially mounted on the side, the raised wiring 100 can be bundled more reliably. However, the projecting piece 200 is not limited to such a shape. Basically, it protrudes from the main body 520 of the cover 52 and
It is only necessary to have a function of grouping zeros, and not only curved ones but also flat ones can be applied. This is because the cover 52 is connected to the upper surface 5 of the connector body 55.
5a is sequentially slid from one end to the other end so as to be attached to the connector main body 55 side, so that the protruding piece 2 integrated with the main body portion 520 of the cover 52 is formed.
This is because when the wiring 100 extending from the upper surface 55a of the connector main body 55 slides from one end of the upper surface 55a to the other end, the wiring 100 functions so as to be bundled little by little. In addition, since the reinforcing flange 200f is provided at the tip of the protruding piece 200, not only the mechanical strength of the entire protruding piece 200 is increased, but also the cover is provided by placing a finger on the reinforcing flange 200f. The work of attaching and detaching 52 can be performed more easily. After the cover 52 is attached, the reinforcing flange 200f and the main body 52 of the cover 52 are removed.
By winding a binding member such as a tape around the portion of the protruding piece 200 between 0 and 0, the wiring 100 can be securely bound.
