As in 1 shown, extends the Y -Axis of XYZ Coordinates in the same direction as the adjustment direction D1 the movement of a mating connector 600 in relation to a plug 500 if the mating connector 600 in the plug 500 fits. The Z Axis extends in the same direction as the thickness direction of a board 700 which is one of the elements on which the plug 500 can be attached. The X Axis extends in the direction perpendicular to both the Y -Axis direction as well Z -Axis direction is.

As in 1 is shown, a plug unit 10 For example, used for electrically connecting electronic circuit parts that are to be adapted to a car. The plug unit 10 includes a plug 500 according to the embodiment and a mating connector 600 ,

The plug 500 is a male plug attached to a circuit board 700 should be attached. The plug 500 includes a housing 510 , Connections 520 and a dust prevention cover 1 to prevent debris from attaching to the terminals 520 to adhere to that of a housing 510 of the plug 500 are unprotected.

As in 2 shown is the housing 510 an element formed of an insulating material, such as resin, approximately in the shape of a hollow quadrangular pillar, the axis of which is along the Y -Axis is aligned and a terminal receiving space 510a for picking up the mating connector 600 Are defined. brackets 510b . 510c are formed to stand out from the side walls of the housing 510 on the side where the connections 520 from the case 510 are unprotected to extend (+ Y Side), with the dust prevention cover 1 on the brackets 510b . 510c should be attached. The housing 510 includes locking parts 511 , Guide grooves 512 and mounting brackets 513 ,

The locking parts 511 are elements that are at the bottom edges 120a the counterpart 120 the dust prevention cover 1 lock when the dust prevention cover 1 on the plug 500 is appropriate. The locking parts 511 are each on the surfaces of the brackets 510b . 510c Made the dust-prevention cover 1 touch. In the illustrated example, one of the locking parts 511 on the surface of the holder 510b on the + X Side is formed and the other is on the surface of the bracket 510c on the - X Page formed.

As in 2 shown, are the guide grooves 512 on the surfaces of the brackets 510b . 510c formed opposite the surfaces where the locking parts 511 are formed in each case along the Z -Axis extend to serve as grooves in which guides 140 the dust prevention cover 1 fit. In the example shown is one of the guide grooves 512 on the surface of the holder 510b on the - X Side is formed and the other is on the surface of the bracket 510c on the + X Page formed.

The mounting brackets 513 are elements for fixing the plug 500 on the board 700 and consist of plates that are bent approximately at a right angle into an L-shape. In the in the 1 and 2 illustrated examples includes each mounting bracket 513 a plate parallel to the mounting surface (the surface on the + Z Side) of the board 700 is, and a plate parallel to the sides ( ZY Level) of the housing 510 is. The mounting brackets 513 are thereby on the housing 510 attached that in the grooves 510d are introduced on the outside surfaces of the housing 510 are formed. The plug 500 is on the board 700 fixed by soldering the mounting brackets 513 at mounting parts 702 the board 700 ,

The connections 520 are made of metal material. As in the section ( c ) from 7 represented, stand the tips 520a the connections 520 on the + Y Side and are from the rear end face of the housing 510 on the + Y Side unprotected. The tips 520a the connections 520 are by soldering to the contacts 701 the board 700 connected to the upper surface (+ Z Side) of the board 700 are unprotected. The tips 520b the connections 520 on the - Y Side stand in the terminal reception room 510a out.

As in the 1 and 2 shown is the dust prevention cover 1 over the tops 520a the connections 520 on the + Y Side of the plug 500 attached and covers the connection part where the connections 520 with the contacts 701 the board 700 (Element to which the plug is attached) are connected. As in 3 shown includes the dust prevention cover 1 a cover 100 , a sealer 200 and an overhang 300 , As in 4 shown are the cover 100 and the sealer 200 separate parts. The sealer 200 is a part of the cover 100 attached and can be removed from this. The cover 100 and the overhang 300 are integrally formed.

The cover 100 is made of insulating resin and integral with the overhang 300 formed by injection molding. The cover 100 includes a top plate 111 , side plates 112 and 113 with respective ends of the top plate 111 are connected and a front plate 114 with one end on the + Y side of the top plate 111 and with respective ends on the + Y side of the side plates 112 . 113 connected is.

The counterparts 120 include vertically long openings (openings that are longer along the Z-axis), each in the side panels 112 . 113 are formed. The counterparts 120 are the parts with which the locking parts 511 of the plug 500 be locked as described later. As in 1 and sections (a) and (b) of 6 shown is the dust prevention cover 1 on the plug 500 fixed when the locking parts 511 of the plug 500 at the lower edges 120a the counterpart 120 be locked. As in 2 shown is the dust prevention cover 1 from the top in the adjustment direction A1 on the plug 500 placed. That is why the counterparts are included 120 vertically long openings.

As in the sections ( b ) and ( d ) from 5 is a concave part 131 which provides a space in which the sealer 200 fits, on the inner surface of the front plate 114 educated. The width (the length along the X Axis) of the concave part 131 is about the same as the width (the length along the X Axis) of the sealer 200 , As in the section ( b ) from 7 shown, the height (the length along the Z Axis) of the concave part 131 slightly smaller than the height (the length along the Z Axis) of the sealer 200 and the depth (the length along the Y Axis) of the concave part 131 is slightly smaller than the thickness (the length along the Y Axis) of the sealer 200 ,

As in the 4 and 5 shown, Fixierpinbohrungen four through holes, which are in the front plate 114 are formed. The fixing pins 220 of the sealer 200 be through the Fixierpinbohrungen 132 introduced as described later. The Fixierpinbohrungen 132 are at regular intervals along the X -Axis formed. As in 4 shown, the fixing pins 220 of the sealer 200 through the Fixierpinbohrungen 132 in the direction of the arrow D2 inserted and in the fixing pin holes 132 locked. The sealer 200 is thus on the cover 100 fixed.

As in the section ( b ) from 5 represented, are the guides 140 integral with the cover 100 formed and include a pair of elements that are along the adjustment direction A1 extend along which the cover 100 moves when the dust prevention cover 1 on the housing 510 attached, as in 2 specified. As in the section ( d ) from 5 presented, have the guides 140 a T-shaped cross-section. Every guide 140 is arranged so that the horizontal bar of the letter T parallel to the Y -Axis runs and one end of the horizontal bar of the letter T with the inside of the front plate 114 connected is. As in section (b) of 6 and the section ( b ) from 7 shown, pass sections of the guides 140 representing the vertical bar of the letter T match, respectively, in the pair of in 2 shown guide grooves 512 in the case 510 are formed when the dust prevention cover 1 on the plug 500 is appropriate.

The guides 140 are provided for the following reasons. As in the section ( b ) from 6 represented, are the guides 140 if the dust prevention cover 1 on the housing 510 of the plug 500 is attached, in the guide grooves 512 press-fitted. As in the section ( b ) from 7 This defines the location of the dust-avoidance cover 1 in relation to the housing 510 along the Y -Axis. The movements along the Y -Ache of the locking parts 511 in the section ( a ) from 6 are shown are thus limited, what the locking parts 511 confined to wobble. Furthermore, as in the section ( b ) from 6 shown, the movements along the X -Axis of dust prevention cover 1 attached to the case 510 is limited, which prevents the dust-preventing cover from wobbling.

As in 4 shown are four recesses 150 in the cover 100 educated.

The sealer 200 is at the cover 100 attached before the dust prevention cover 1 to the plug 500 is adjusted. The arrow D2 indicates the direction in which the sealer 200 is appropriate. The sealer 200 is an element that separates the space between the cover 100 and the board 700 sealed. The sealer comprises a body 210 and fixing pins 220 ,

As in the 4 and 8th represented, is the body 210 formed approximately in the shape of a rectangular column. As in the section ( b ) from 7 shown, touches the front surface 211 of the body 210 an area 131 of the concave part 131 the front plate 114 the cover 100 when the sealer 200 on the cover 100 is appropriate. The upper surface 213 touches a surface 131b of the concave part 131 the cover 100 if the dust prevention cover 1 to the plug 500 is adjusted. The lower surface 212 touches the board 700 if the dust prevention cover 1 to the plug 500 is adjusted.

A convex part 215 that in the + Y Direction protrudes, is at the lower section (- Z Side) of the front surface 211 of the body 210 of the sealer 200 educated. As in 4 and the sections ( a ) and ( b ) from 8th is the convex part 215 formed to run along the X -Axis to extend, to prevent the to the cover 100 adapted sealers 200 out of alignment. As in section (b) of 7 shown, pushes when the dust prevention cover 1 on the housing 510 of the plug 500 on the board 700 attached, the lower end (the end on the - Z Side) of the front panel 114 the convex part 215 in the - Z Direction (towards the circuit board 700 ). As a result, it prevents the cover from being hit 100 adapted sealers 200 out of alignment.

As in the section ( c ) from 8th is a convex part 216 on the lower surface 212 of the body 210 of the sealer 200 so provided that it from the bottom surface 212 protrudes downwards and down the X -Axis extends to prevent foreign objects from entering the dust-prevention cover 1 reach. If the dust prevention cover 1 to the plug 500 adjusted is the sealer 200 between the cover 100 and the board 700 wedged and compressed. The convex part 216 coming from the lower surface 212 protrudes, it allows the sealer 200 , the space between the cover 100 and the board 700 to seal without leaving a gap.

As in the 4 and 8th shown are fixing pins 220 for fixing the sealer 200 on the cover 100 on the front surface 211 of the body 210 of the sealer 200 educated. As in 4 shown, the fixing pins 220 through the Fixierpinbohrungen 132 the cover 100 in the direction of the arrow D2 inserted and in the fixing pin holes 132 locked.

As in the sections (a ) and ( b ) from 8th illustrated, includes each fixing pin 220 a conical section 221 which is formed approximately in a conical shape, an axial portion 222 that the conical section 221 and the body 210 combines. The diameter r1 the top of the conical section 221 is smaller than the diameter R the fixing pin hole 132 in the section ( a ) from 5 shown. Furthermore, the conical section has 221 , as in the sections ( a ) to ( c ) from 8th presented a tapered shape, giving it the fixation pin 220 allows smoothly into the Fixierpinbohrung 132 to be introduced.

The diameter r2 of the conical section 221 at the thickest portion of it is larger than the diameter R the fixing pin hole 132 , presented in the section ( a ) from 5 , This serves to prevent the fixation pin 220 from the Fixierpinbohrung 132 is pulled as soon as the fixing pins 220 in the Fixierpinbohrungen 132 be introduced from the top section thereof as in the 3 and 4 shown and the axial section 222 reaches the Fixierpinbohrungen 132 as in the section ( c ) from 7 shown.

The diameter r3 of the axial section 222 , presented in the section ( b ) from 8th , is slightly larger than the diameter R the fixing pin hole 132 , presented in the section ( a ) from 5 , As in the section ( c ) from 7 shown is the axial section 222 compressed when the axial section 222 through the fixing pin hole 132 is introduced, which prevents foreign bodies through the Fixierpinbohrung 132 in the dust prevention cover 1 reach.

As in the 3 and 4 shown, the overhang extends 300 from the top plate 111 the cover 100 in the - Y -Direction. As in 2 represented, is the overhang 300 an element that surrounds the boundary portion B between the cover 100 and the housing 510 of the plug 500 covers. As in the section ( c ) from 5 represented, is the overhang 300 formed so that it is not horizontal, but slightly down (into the - Z Direction) extends in relation to the horizontal direction. Further, the outer end portion of the overhang is 300 formed as a bendable free end.

As in the sections ( b ) and ( c ) from 7 represented, the overhang touches 300 if the dust prevention cover 1 on the housing 510 of the plug 500 attached, the upper surface of the housing 510 of the plug 500 , The overhang 300 which extends slightly downwards (into the Z Direction) in relation to the horizontal direction and which is bendable, enables the dust-preventing cover 1 , on the plug 500 to be attached, leaving no gap at the boundary between the cover 100 and the upper surface of the housing 510 leaves.

As in 1 shown, is the mating connector 600 a female plug, in the cable 601 are connected to female terminals (not shown). The mating connector 600 will be in the adjustment direction D 1 in the connection reception room 510a of the plug 500 introduced. The mating connector 600 fits in the plug 500 if a part of the mating connector 600 in the terminal receiving space 510a of the plug 500 is recorded.

It should be noted that the mating connector 600 can be structured in any way, as long as the mating connector 600 to the plug 500 fits. The female plug in 1 is shown only one example and the number of cables, the shape of the housing and the like, which refers to the mating connector 600 can be changed if necessary.

The board 700 is a printed circuit board that has a front surface on the + Z Page, on the contacts 701 and mounting parts 702 unprotected, and a rear surface on which no contacts 701 are arranged. The plug 500 is on the board 700 appropriate.

An example method of producing the dust-preventing cover 1 is described.

First, a worker to make the dust-preventing cover prepares an integrally molded product of the cover 100 and the overhang 300 as in 4 presented before. This integrally molded product is manufactured by injection molding. The sealer 200 is also prepared.

The sealer 200 will be in the direction of the arrow D2 to the integrally molded product of the cover 100 and the overhang 300 moved towards and against the inner surface of the front plate 114 pressed. At this time, the fixing pins 220 in the Fixierpinbohrungen 132 introduced. If the fixing pins 220 through the Fixierpinbohrungen 132 are introduced, the arrangement of the dust prevention cover 1 of the integrally molded product and the sealer 200 completely as in 3 shown.

The dust prevention cover 1 is on the plug 500 attached in the following way. Like from the 1 and 2 can be seen, are the mounting brackets 513 and the connections 520 on the plug 500 attached, the mounting brackets 513 are to the attachment parts 702 on the board 700 soldered and the connections 520 are in advance to the contacts 701 on the board 700 soldered. In this state, the dust-preventing cover becomes 1 from the top along the adjustment direction A1 on the plug 500 placed as in 2 shown. At this time, the dust prevention cover becomes 1 along the adjustment direction A1 moved and on the plug 500 placed while the relative positions of the counterparts 120 and the locking parts 511 on the X -Axis and on the Y -Axis adapted to the locking parts 511 to allow in the openings of the counterparts 120 to fit like in 2 shown. While the dust prevention cover 1 is moved along, the inner surfaces of the side plates 112 and 113 the dust prevention cover 1 along the slopes of the locking parts 511 guided and, if the dust prevention cover 1 is moved to a certain position, the locking parts 511 on the lower edges 120a locked as in the 1 and 6 shown. The dust prevention cover 1 becomes so on the plug 500 attached as in 1 shown.

If the dust prevention cover 1 on the plug 500 is attached and the locking parts 511 with the counterparts 120 becomes the sealer 200 thereby on the board 700 pressed, as in the sections ( b ) and ( c ) from 7 shown. This will prevent foreign objects from entering the dust prevention cover from the outside 1 reach. This concludes the description of the dust prevention cover 1 according to the present embodiment.

As described above, according to the present embodiment, foreign objects become an overhang 300 who is the border section B between the cover 100 and the housing 510 covers, is provided and the overhang 300 bends when he gets the case 510 touched, while limited, at the border section B between the cover 100 and the housing 510 get in.

Further, the dust prevention cover includes 1 according to the present embodiment, a sealer 200 that the space between the cover 100 and the board 700 sealed. This sealer 200 fills the gap between the cover 100 and the board 700 whereby foreign matter is confined therein into the dust-preventing cover 1 to get.

Furthermore, the sealer 200 , according to the present embodiment, against the board 700 pressed and compressed by locking the locking parts 511 of the housing 510 with the counterparts 120 the dust prevention cover 1 , This further increases the beneficial effects of restricting foreign bodies therein into the dust-preventing cover 1 to get.

Further, according to the present embodiment, the guides fit 140 the cover 100 in the guide grooves 512 of the housing 510 , As described above, this limits the dust prevention cover 1 to run out of alignment when attached to the case 510 is appropriate. It is thus prevented that the dust prevention cover 1 wobbles. Furthermore, this also limits the on the housing 510 attached dust prevention cover 1 in being lifted by the reaction force, by bending the overhang 300 that's the case 510 touched, caused.

The embodiment of the present disclosure has been described, but the present disclosure is not limited to the embodiment described above.

Modified Example 1

In the embodiment described above, an example in which the outer end of the overhang 300 passing the boundary section B between the cover 100 and the housing 510 of the plug 500 covering, is flat as in the 2 and 3 described. The outer end of the overhang 300 may have any shape as long as it is a shape restricting foreign matters therein at the boundary portion B between the cover 100 and the housing 510 get in. A dust prevention cover 2 according to Modified Example 1, in which the overhang 300 is formed differently, with reference to the 9 to 12 described. The dust prevention cover 2 according to Modified Example 1 comprises a sealer 201 that is integral with a cover 101 is shaped. In the following description of the modified example 1 For example, characteristics similar to those of the embodiment will not be described, and characteristics different from those of the embodiment will be mainly described. 12 Fig. 10 is a cross-sectional view of the male connector and the dust-preventing cover 2 along a line in the same position as the CC Line in the section ( a ) from 7 ,

As in the 9 and 10 shown includes the dust prevention cover 2 a cover 101 , a sealer 201 and an overhang 301 , The sealer 201 is about the same position relative to the cover 101 arranged as in the embodiment. However, in Modified Example 1, the cover 101 and the sealer 201 an insert molded product integrally molded by insert molding, as in FIGS 9 and 10 shown. Therefore, the sealer 201 not from the cover 101 be solved.

As in 11 shown is no Fixierpinbohrung in the front plate 114 the cover 101 formed, in contrast to the embodiment. A lower section (- Z Side) of the front panel 114 the cover 101 is cut off at about the same width as that of the sealer 201 and at such a height that cutting the recesses 150 not impaired. At a point where the sealer 201 is to be provided is a basis 134 formed to be a plate-shaped member extending from the lower end of the front plate 114 extends. The sealer 201 is by introduction molding at this base 134 educated. There are also four drill holes 134a in the base 134 provided. The material of the sealer 201 fills the punctures 134a during insertion. This prevents the sealer 201 from the cover 101 drops.

Furthermore, as in 9 represented, a convex part 310 to serve as a fitted part, at the outer end of the overhang 301 formed on the -Z side, in contrast to the embodiment. It also fits as in 12 represented, a concave part 514 which is to serve as a fitting part in which the convex part 310 fits, on the case 510 formed at the point where the outer end of the overhang 301 the housing 510 touched. This property prevents the overhang 301 out of alignment when the dust prevention cover 2 on the housing 510 is appropriate. Further, the convex part 310 , for the overhang 301 is provided, the contact between the convex part 310 and the housing 510 Safely determine what foreign matter is confined to, at the boundary between the housing 510 and the outer end portion of the overhang 301 get in. It should be noted that, even if no concave part 514 on the housing 510 is provided with a convex part 310 provided overhang 301 the beneficial effects of confining foreign bodies therein, at the boundary between the housing 510 and the outer end portion of the overhang 301 get in, produced.

As described above in Modified Example 1, the convex part prevents 310 which is at the outer end of the overhang 301 the cover 101 is provided and in the concave part 514 fits in the case 510 is formed, that the overhang 301 goes out of alignment when the dust prevention cover 2 on the housing 510 is attached, and confines foreign matter therein, at the boundary between the housing 510 and the outer end portion of the overhang 301 enter.

It also fills, as in 12 shown, the sealer 201 the dust prevention cover 2 the gap between the cover 101 and the board 700 Also in the present Modified Example 1, whereby foreign matters are restricted therein, into the dust-preventing cover 2 enter. Therefore, Modified Example 1 also produces similar advantageous effects as in the embodiment.

Furthermore, the dust prevention cover has 2 a more compact structure than in the embodiment, since the cover 101 and the sealer 201 are integrally formed to be an insert-molded product in Modified Example 1.

Modified Example 2

In Modified Example 1 described above, an example was described in which a convex part 310 which is to serve as a fitted part at the outer end of the overhang 301 is formed and a concave part 514 which is to serve as a fitting part in which the convex part 310 fits, on the case 510 formed at the point where the outer end of the overhang 301 the housing 510 touched. The fitted part attached to the overhang 301 is formed and the fitting part attached to the housing 510 can be formed, as long as the shapes match each other. A concave part to serve as a fitted part may be at the outer end of the overhang 301 may be formed on the housing and a convex part, which is to serve as a matching part 510 be formed. Furthermore, a convex-concave part on the overhang 300 be formed and a convex-concave part can be attached to the housing 510 be formed to that on the overhang 300 formed convex-concave part to fit.

The foregoing describes some exemplary embodiments, those skilled in the art will recognize that changes may be made in form and detail without departing from the broader spirit and scope of the invention. Accordingly, the specification and the drawings are to be considered as illustrative and not restrictive. Therefore, this detailed description is not to be taken in a limiting sense, and the scope of the invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.

This application claims the advantage of Japanese Patent Application No. 2018-056078 , filed March 23, 2018, the entire disclosure of which is incorporated herein by reference.
