The housing includes a housing body 14 dividing an insertion recessed portion 13, an adsorbed portion 27 formed so as to bulge out from the housing body in a drawing direction X11, and a locked portion 32 formed on an outer surface 21a of a first side wall 21 on the drawing direction side of the housing body and united with a locking member 54 of a socket connector 3. The contact includes a contact body 37 disposed in the insertion recessed portion, and a lead portion 38.

Description

  The present invention relates to a surface mount type base connector and a connector unit including the same.

A surface mount type connector that supports automatic mounting is supplied to the market in a state of being accommodated in an embossed carrier tape, for example. The embossed carrier tape is composed of a band-shaped carrier tape main body in which a bathtub-shaped case portion that accommodates one surface-mounted connector one by one and a belt-shaped protective sheet that is peelably bonded to the carrier tape main body and covers the case portion. .
An automatic mounting machine for automatically mounting a surface mount connector on a wiring board includes a suction member (for example, an air nozzle) that sucks and holds the surface mount connector. This automatic mounting machine operates to sequentially feed the embossed carrier tape while peeling off the protective sheet, and to take out the surface-mounted connector in the case portion and place it at a predetermined position on the surface of the wiring board by the suction member.

In order to securely hold the surface-mounted connector by the suction member, it is necessary to provide a sufficiently large flat suction surface on the upper surface of the surface-mounted connector.
It has been proposed to provide this attracted surface on a attracted member that is detachably attached to the housing of the connector (see, for example, Patent Document 1).
The adsorbed member includes a main body portion having an adsorbed surface formed on an upper surface and a pair of pressing portions extending downward from the main body portion. The pair of pressing portions are disposed in the receiving space of the housing. The socket connector is inserted into the receiving space after the connector is mounted on the board. The pair of pressing portions are in frictional contact with the housing by pressing the side wall of the housing toward the outside of the housing in the receiving space. Thereby, the to-be-adsorbed member is attached to the housing. The attracted surface is disposed at the center of the insertion recess in plan view.

  When the attracted member is lifted, the connector housing is also lifted, so that the connector can be moved for automatic mounting. Moreover, since the attracted surface is disposed at the center of the connector (center of gravity of the housing), the load balance when the attracting member lifts the attracted member and the connector is good. Thereby, it can prevent that the to-be-adsorbed member and connector when it is lifted by the attracting member can be tilted with respect to the horizontal plane, and can transport these to-be-adsorbed member and connector in a stable posture. After the connector is fixed to the surface of the wiring board, the member to be sucked is removed from the housing of the connector by lifting the member to be sucked.

  However, in the above configuration, it is necessary to prepare a sucked member that is a separate member from the housing in order to surface-mount the connector on the substrate, which increases the number of parts and the manufacturing cost. Therefore, it is conceivable to omit the member to be attracted and provide the surface to be attracted on the housing itself. In this case, for example, it is conceivable to provide the attracted surface on the upper surface of the side wall defining the receiving space in the housing.

  However, when a suction surface is provided on the side wall of the receiving space in the connector, the suction surface is arranged at a position shifted from the center position of the housing in plan view. For this reason, the housing is adsorbed by the adsorbing member at a position shifted from the central position of the housing. In the case of such adsorption, the load balance of the housing when it is lifted by the adsorption member is poor, and the housing tends to tilt with respect to the adsorption member. As a result, the housing may not be accurately placed at a desired position on the substrate. In order to suppress such inclination, it is conceivable to increase the suction force between the suction member and the suction surface by increasing the area of the suction surface.

However, the surface-mount type connector is sometimes disposed in a narrow space such as the back side of the display panel of the liquid crystal display device, and is required to be downsized. An increase in the attracted surface is not preferable because it leads to an increase in the size of the connector.
SUMMARY OF THE INVENTION An object of the present invention is to provide a surface mount type base connector that can lift a connector in a balanced manner by a suction member without providing a separate member dedicated for suction during automatic mounting, and can be downsized. It is to be.

  Another object of the present invention is to provide a connector unit having such a base connector.

  In order to achieve the above object, the invention according to claim 1 is a surface mount type base connector coupled to a socket connector having a lock member, and is opposed to a mounting board from a socket side that accepts the socket connector. An insulating housing that accepts the socket connector along a socket insertion direction toward the board side, and a plurality of conductive contacts that are held in the housing and are arranged in a contact arrangement direction orthogonal to the socket insertion direction. The housing has a rectangular parallelepiped housing body that opens to the socket side and defines an insertion recess into which the conductive portion of the socket connector is inserted along the socket insertion direction, and the socket insertion direction and the contact arrangement direction. The socket side of the housing body along a perpendicular extending direction A portion to be sucked that has a surface to be sucked and is perpendicular to the insertion direction of the socket; and a portion to be locked that is formed on the outer surface of the side wall of the housing body on the side of the protruding direction and is coupled to the lock member of the socket connector. The contact includes a contact portion that can contact the conductive portion of the socket connector, the contact main body disposed in the insertion recess, and extends from the contact main body in the protruding direction on the substrate side. And a lead portion having a connection end drawn in the protruding direction from the outer surface of the side wall of the housing body on the protruding direction side.

  According to the present invention, the suction surface is provided on the housing itself. Therefore, the base connector can be lifted and mounted on the surface of the mounting board by adsorbing the attracted surface with the adsorbing member. There is no need to attach a separate member dedicated to the suction member to the base connector, and the number of parts and the manufacturing cost can be reduced. Further, the connection ends of the attracted portion, the locked portion, and the lead portion are arranged close to the protruding direction side portion of the housing. Thereby, the center-of-gravity position of the base connector can be close to the attracted portion. Therefore, the base connector can be lifted in a well-balanced manner by attracting and lifting the attracted surface by the attracting member. Further, for example, when the connection ends of the attracted portion, the locked portion, and the lead portion are distributed and arranged in the overhanging direction side portion and the opposite side portion of the housing, the base connector in the direction parallel to the overhanging direction The thickness will increase. On the other hand, in this invention, as above-mentioned, the to-be-adsorbed part, the to-be-locked part, and the connection end of a lead part are arranged near the overhang | projection direction side part in a housing. Thereby, the thickness of the base connector in a direction parallel to the protruding direction can be reduced. As a result, it is possible to reduce the size of the base connector through thinning the base connector. Further, a space above the connection end of the lead portion drawn out in the protruding direction from the side wall on the protruding direction side of the housing body for connection with the mounting board is vacant. In this vacant space, the attracted part is arranged. Thus, the three-dimensional arrangement of the lead portion and the attracted portion can further reduce the thickness of the base connector in the direction parallel to the protruding direction.

According to a second aspect of the present invention, the locked portion has a first locked portion and a second locked portion that are spaced apart from each other in the contact arrangement direction, as viewed from the socket insertion direction. The base connector according to claim 1, wherein the attracted portion is disposed between the first and second locked portions.
According to the present invention, the load balance of the base connector in the contact arrangement direction can be improved by arranging the locked parts apart in the contact arrangement direction. As a result, it is not necessary to provide the housing only with a portion for adjusting the load balance, and the base connector can be downsized through the downsizing of the housing.

The invention according to claim 3 is the base connector according to claim 1 or 2, wherein the housing further includes a projecting wall projecting in the projecting direction from the housing body.
According to the present invention, the position of the center of gravity of the base connector can be brought closer to the protruding direction side (adsorbed member side) by the protruding wall. Thereby, the adsorbing member can lift the base connector in a more balanced manner. Moreover, a small protrusion (protrusion wall) may be provided in order to exert this balance improvement effect, and the base connector can be downsized. Further, even when the housing is inclined when the suction member places the base connector on the mounting surface of the mounting substrate, the inclination can be corrected by contact between the protruding wall and the mounting surface.

The invention according to claim 4 is the base connector according to claim 3, wherein the protruding wall includes a first protruding wall and a second protruding wall arranged at both ends of the housing body in the contact arrangement direction.
According to the present invention, the load balance of the base connector in the contact arrangement direction can be improved. In addition, in order to exert this balance improvement effect, a small protrusion (protrusion wall) may be provided at the end of the housing body, and the base connector can be downsized.

According to a fifth aspect of the present invention, a lock member housing space for housing the lock member of the socket connector is formed by the side wall in the projecting direction of the housing body and the first and second projecting walls. The base connector according to claim 4.
According to this invention, the member which partitions the lock member accommodation space of the socket connector is arrange | positioned at the protrusion direction side of the base connector. Thereby, the position of the center of gravity of the base connector can be made closer to the attracted surface. Further, when the lock member of the socket connector is coupled to the base connector, the lock member is located in the accommodation space. Thereby, it can suppress that a locking member protrudes in an overhang direction with respect to a base connector. Therefore, it is possible to realize a reduction in size when viewed as a whole connector unit including a base connector and a socket connector. Furthermore, the connection end of the lead portion of the contact is positioned in the lock member accommodation space. Thereby, when the base connector and the socket connector are fitted, the lock member covers the connection end of the lead portion. Therefore, a lock member can be used as a member that protects the connection end of the lead portion.

Thereby, the center-of-gravity position of the base connector can be closer to the attracted surface while the base connector is thinned in the protruding direction. Further, the connection end of the lead portion can be protected by the end portion of the protruding wall.

According to a seventh aspect of the present invention, the projection wall includes a groove portion disposed behind the front end portion in the protruding direction and opened toward the downstream side in the socket insertion direction. It is a base connector as described in an item.
According to the present invention, the load balance of the base connector can be adjusted by the size of the groove, and as a result, the load balance of the base connector can be further improved. In addition, since this effect can be achieved without increasing the protruding wall, the base connector can be further downsized. Furthermore, the tip of the projection wall in the socket insertion direction can be arranged at a position far from the housing body in the protruding direction. This makes it possible to more reliably suppress the housing from falling when the suction member places the housing of the base connector on the mounting surface of the mounting board by the contact between the end of the protruding wall and the mounting surface.

The invention according to claim 8 is the base connector according to any one of claims 1 to 7, further comprising a reinforcing tab fixed to a side wall of the housing body on the upstream side in the protruding direction.

Thereby, the load balance of the base connector in a direction parallel to the overhang direction can be improved. Moreover, the reinforcement tab is arrange | positioned on the opposite side of the part in which the to-be-locked part and to-be-adsorbed part concentrate in the housing. As a result, the portion of the housing on the side of the protruding direction with respect to the insertion recess is not excessively enlarged, and as a result, the base connector can be reduced in size. Further, after the surface mounting in which the contact lead portion and the reinforcing tab are fixed to the mounting substrate, a tensile force may be generated from the socket connector lock member to the housing. This pulling force can be received in a well-balanced manner in the direction parallel to the extending direction (supporting two points) between the lead portion and the reinforcing tab. Thereby, it can suppress more reliably that a base connector peels from a mounting substrate.

  The lock member main body 65 is arranged side by side with the base end portion 55 in the front-rear direction X1. The fulcrum parts 63 and 64 are connected to the lock member main body 65. A knob 65 a is provided at the upper end of the lock member main body 65. The lock member 54 can be swung by picking the knob 65a with a finger or the like. Thereby, each arm part 66 and 67 is displaced to the front-back direction X1.

  As shown in FIG. 3A, FIG. 3B, and FIG. 3C, the first arm portion 66 is arranged side by side with the insertion convex portion 56 in the front-rear direction X1. A first claw portion 71 is formed at the distal end portion of the first arm portion 66. The first claw portion 71 is a bowl-shaped portion that protrudes from the first arm portion 66 toward the insertion convex portion 56. The first claw portion 71 extends across the entire left and right of the first arm portion 66.

  The second arm portion 67 is formed in a shape symmetrical to the first arm portion 66. That is, the second arm portion 67 is arranged side by side with the insertion convex portion 56 in the front-rear direction X1. A second claw portion 72 is formed at the distal end portion of the second arm portion 67. The second claw portion 72 is a hook-shaped portion that protrudes from the second arm portion 67 toward the insertion convex portion 56. The second claw portion 72 extends across the entire left and right of the second arm portion 67. The first claw portion 71 and the second claw portion 72 form a claw portion 70 as a lock portion.

  The lock member 54 has an adsorbed part receiving part 73 formed by the lock member main body 65, the first arm part 66 and the second arm part 67. A receiving portion 74 is formed at the upper end portion of the attracted portion receiving portion 73, that is, at the lower end portion of the lock member main body 65. The receiving portion 74 is disposed between the first claw portion 71 and the second claw portion 72 when viewed from the socket insertion direction Z11.

As shown in FIG. 1, the length L1 from the lower end surface 55b of the base end portion 55 of the socket housing main body 53 to the claw portion 70 in the socket insertion direction Z11 is the upper surface 21b of the first side wall 21 of the base connector 2. To approximately the length L2 from the locked portion 32 to the locked portion 32.
As shown in FIG. 5, the base connector 2 is supplied to the market while being accommodated in the embossed carrier tape 100. The embossed carrier tape 100 includes a carrier tape main body 101 and a protective sheet 102 that is detachably attached to the carrier tape main body 101.

The carrier tape main body 101 is a band-shaped body in which bathtub-shaped case portions 103 for accommodating the base connectors 2 one by one are continuously formed at intervals along the longitudinal direction. The base connector 2 is accommodated in the case portion 103 of the carrier tape body 101 in the same posture as the mounting state of the base connector 2 when the mounting substrate 4 is horizontally disposed.
That is, when the carrier tape 100 is horizontally extended so that the protective sheet 102 is positioned upward, the attracted surface 27 a of the base connector 2 faces upward from the upper opening of the case portion 103. It is accommodated in the part 103.

An automatic mounting machine for automatically mounting the base connector 2 on the mounting substrate 4 winds the embossed carrier tape 100 from the reel and sequentially feeds the protective sheet 102 in synchronism with the operation and timing of the progressive mechanism. And a protective sheet take-up mechanism.
The progressive feed mechanism horizontally extends the embossed carrier tape 100 so that the protective sheet 102 is on the upper side. In this state, the protective sheet 102 is wound up by the protective sheet winding mechanism. As a result, the protective sheet 102 is peeled off from the carrier tape main body 101, and the attracted surface 27 a of the base connector 2 is exposed upward from the upper opening of the case portion 103.

The exposed suction surface 27a is sucked and held by the suction member 104 of the automatic mounting machine. The adsorption member 104 is coupled to an adsorption member drive mechanism for moving the adsorption member 104 back and forth, right and left, and up and down, and this adsorption member drive mechanism is controlled by a control unit (an apparatus including a microcomputer).
The suction member drive mechanism is controlled by the control unit to move the suction member 104 to the case portion 103 guided to a predetermined suction position and suck and hold the base connector 2 accommodated in the case portion 103. Let Then, the suction member driving mechanism moves the suction member 104 upward and takes out the base connector 2 from the case portion 103. The adsorbing member 104 directly adsorbs and holds the adsorbed surface 27a of the base connector 2 by air suction.

Thereafter, as shown in FIG. 6, the suction member drive mechanism moves the suction member 104 to the wiring board placement portion 105, and at a predetermined position on the mounting substrate 4 placed in advance on the wiring board placement portion 105. The base connector 2 is conveyed.
When the suction member 104 places the base connector 2 on the mounting substrate 4, the housing 11 of the base connector 2 may be inclined as shown in FIG. However, this inclination is suppressed by the protruding wall 15 (the lower end portion 34c of the protruding wall 34, etc.). Therefore, the base connector 2 can be accurately placed at the regular position on the mounting substrate 4.

Thereafter, the suction of the attracted surface 27a by the attracting member 104 is released, so that the base connector 2 is mounted at a normal position on the mounting substrate 4 as shown in FIG. 2C.
Cream solder (not shown) is disposed in advance on the land on the mounting substrate 4. The base connector 2 is mounted so that the connection end 38a of the lead portion 38 of the contact 12 and the reinforcing tabs 46 and 47 are in contact with the cream solder. By passing the mounting substrate 4 in this state through the reflow bath, the cream solder is melted. Further, the solder is cured through a subsequent cooling step, whereby permanent contact between the contact 12 and the reinforcing tabs 46 and 47 and the mounting substrate 4 is achieved.

Next, an operation for attaching the socket connector 3 to the base connector 2 will be described.
As shown in FIG. 7A, when attaching the socket connector 3 to the base connector 2, first, the socket housing body 53 of the socket connector 3 is disposed above the insertion recess 13 of the base connector 2. Then, the lock member 54 is positioned above the lock member accommodation space 35. In this state, the insertion convex portion 56 of the socket connector 3 is displaced along the socket insertion direction Z11 and inserted into the insertion concave portion 13 of the base connector 2.

Then, as shown in FIG. 7B, the conductive portion 52 of the socket connector 3 contacts the corresponding contact 12 of the base connector 2. As a result, an electric path is formed between the mounting substrate 4 and the covered electric wire 5 via the contact 12 and the conductive portion 52.
At this time, when the first claw portion 71 of the lock member 54 comes into contact with the first inclined portion 28 of the first overhang portion 25, the lock member 54 swings. At this time, although not shown, the second claw portion 72 is in contact with the second inclined portion 30 of the second overhang portion 26.

  When the socket connector 3 is further inserted in the socket insertion direction Z11, the entire insertion convex portion 56 fits into the insertion concave portion 13 as shown in FIG. Thereby, the elastic piece part 60b and the side surface 60f of the conductive part 52 of the socket connector 3 and the convex part 41a and the one edge part 42a of the corresponding contact 12 of the base connector 2 contact. At this time, the first claw portion 71 of the lock member 54 gets over the first overhanging portion 25 and is coupled to the first locked portion 29 of the first overhanging portion 25. Although not shown, at the same time, the second claw portion 72 of the lock member 54 gets over the second overhanging portion 26 and is coupled to the second locked portion 31 of the second overhanging portion 26.

  Thereby, the locked state in which the socket connector 3 is locked to the base connector 2 is achieved. At this time, as shown in FIG. 8A, the receiving portion 74 of the lock member 54 is in direct contact with the attracted surface 27 a of the base connector 2. Since the receiving portion 74 and the attracted surface 27a are exposed in the extending direction X11 in the fitted state of both the connectors 2 and 3, the contact state of the receiving portion 74 and the attracted surface 27a is visually observed from the front. Can be confirmed.

At this time, since the claw portion 70 (the first claw portion 71 and the second claw portion 72) of the lock member 54 is disposed in the lock member accommodating space 35, the connection between the claw portion 70 and the locked portion 32 is established. Inadvertent release can be prevented.
Assume that the socket connector 3 is inserted into the base connector 2 while being tilted and the connectors 2 and 3 are not fitted (half-fitted state). In this case, as shown in FIG. 8B, the receiving part 74 is lifted with respect to the attracted surface 27 a of the base connector 2 and is not in contact with the receiving part 74. Thereby, it can be visually confirmed that the socket connector 3 is not fitted to the base connector 2.

When removing the socket connector 3 from the base connector 2, as shown in FIG.7 (b), the knob | pick part 65a of the lock member 54 is pushed back with a finger | toe. As a result, the lock member 54 rotates about the fulcrum portions 63 and 64, and the claw portion 70 is lifted in the protruding direction X <b> 11, which is a direction away from the housing 11, and the engaged state with the locked portion 32 is established. Canceled.
In this state, when the operator pulls out the socket connector 3 in the direction opposite to the socket insertion direction Z11 (upward), the insertion convex portion 56 of the socket connector 3 is separated from the insertion concave portion 13, and the socket connector 3 is removed from the base connector 2. Can be pulled out.

  As described above, according to this embodiment, the suction surface 27a is provided on the housing 11 of the base connector 2 itself. Therefore, the base connector 2 can be lifted and mounted on the mounting surface 4 a of the mounting substrate 4 by sucking the attracted surface 27 a with the attracting member 104. There is no need to attach a separate member dedicated to the suction member 104 to the base connector 2, and the number of parts and the manufacturing cost can be reduced.

  Further, the connection end 38 a of the attracted portion 27, the locked portion 32, and the lead portion 38 are arranged close to the protruding direction X 11 side portion of the housing 11. Thereby, the center-of-gravity position G1 of the base connector 2 can be close to the attracted portion 27. Accordingly, the base member 2 can be lifted in a balanced manner by the suction member 104 attracting and lifting the attracted surface 27a.

For example, the thickness of the base connector in the front-rear direction parallel to the overhanging direction when the connection ends of the attracted part, the locked part and the lead part are distributed in the overhanging direction side part and the opposite side part of the housing. Will become thicker.
On the other hand, in this embodiment, as described above, the attracted portion 27, the locked portion 32, and the connection end 38a of the lead portion 38 are arranged close to the protruding direction X11 side portion of the housing 11. Thereby, the thickness of the base connector 2 in the front-back direction X1 parallel to the protruding direction X11 can be reduced. As a result, the base connector 2 can be reduced in size through the thinning of the base connector 2.

  Further, a space above the connection end 38 of the lead portion 38 drawn out in the extending direction X11 from the first side wall 21 of the housing body 14 for connection with the mounting substrate 4 is vacant. The attracted part 27 is arranged in this vacant space. Thus, the three-dimensional arrangement of the lead portion 38 and the attracted portion 27 can further reduce the thickness of the base connector 2 in the front-rear direction X1 parallel to the protruding direction X11.

  Further, the suctioned portion 27 is disposed between the first and second locked portions 29 and 31 when viewed from the socket insertion direction Z11. That is, the load balance of the base connector 2 in the left-right direction Y1 can be improved by arranging the first and second locked parts 29, 31 apart in the left-right direction Y1. As a result, it is not necessary to provide the housing 11 with a portion only for improving the load balance in the left-right direction Y1, and the base connector 2 can be downsized through the downsizing of the housing 11.

  Furthermore, the center of gravity position G1 of the base connector 2 can be brought closer to the projecting direction X11 side (the attracted part 27 side) by the first and second projecting walls 33 and 34. Thereby, the adsorption member 104 can lift the base connector 2 in a more balanced manner. And in order to exhibit this balance improvement effect, it is sufficient to provide small protrusions (protrusion walls 33 and 34), and the base connector 2 can be miniaturized. Furthermore, when the suction member 104 places the base connector 2 on the mounting surface 4a of the mounting substrate 4, even if the housing 11 is inclined, the lower ends 33c and 34c of the protruding walls 33 and 34, the mounting surface 4a, This inclination can be corrected by contact of.

In addition, by providing the projecting walls 33 and 34 at the left and right ends of the housing body 14, the load balance of the base connector 2 in the left-right direction Y1 can be improved. In addition, small projections (projection walls 33 and 34) may be provided on the left and right ends of the housing body 14 in order to exhibit this balance improvement effect, and the base connector 2 can be downsized.
Further, the first side wall 21 and the projecting walls 33 and 34 as members that divide the lock member accommodation space 35 are arranged on the side of the base connector 2 in the extending direction X11. Thereby, the gravity center position G1 of the base connector 2 can be made closer to the attracted surface 27a. Further, when the lock member 54 of the socket connector 3 is coupled to the locked portion 32 of the base connector 2, the claw portion 70 of the lock member 54 is located in the lock member accommodation space 35. Thereby, it can suppress that the locking member 54 protrudes with respect to the base connector 2 in the protrusion direction X11. Accordingly, it is possible to realize a reduction in size when viewed as a whole of the connector unit 1 including the base connector 2 and the socket connector 3.

Further, the connection end 38 a of the lead portion 38 of the contact 12 is positioned in the lock member accommodation space 35. Thereby, when the base connector 2 and the socket connector 3 are fitted, the lock member 54 covers the connection end 38a of the lead portion 38 from above. Therefore, the lock member 54 can be used as a member that protects the connection end 38 a of the lead portion 38.
Further, the lower end portions 33b, 34b of the projection walls 33, 34 are aligned with the connection end 38a of the lead portion 38 in the socket insertion direction Z11. In this way, by extending the protruding walls 33 and 34 in the socket insertion direction Z11, the mass of the protruding walls 33 and 34 is increased while reducing the amount of protruding the protruding walls 33 and 34 in the protruding direction X11. be able to. Thereby, the position of the center of gravity of the base connector 2 can be closer to the attracted surface 27a while making the base connector 2 thin in the extending direction X11. Further, the connection end 38a of the lead portion 38 can be protected from the left and right by the lower end portions 33b, 34b of the projection walls 33, 34.

  In addition, the load balance of the base connector 2 can be adjusted by setting the size of the groove portions 33c, 34c of the projection walls 33, 34. As a result, the load balance of the base connector 2 can be further improved. Moreover, since this effect can be achieved without increasing the protruding walls 33 and 34, the base connector 2 can be further downsized. Furthermore, the tip end portion in the socket insertion direction Z11 of the projecting walls 33 and 34 can be arranged at a position far from the housing body 14 in the protruding direction X11. As a result, the housing member 11 falls when the suction member 104 places the housing 11 of the base connector 2 on the mounting surface 4a of the mounting substrate 4. The lower end portions 33c and 34c of the protruding walls 33 and 34 and the mounting surface 4a It can be surely suppressed by contact.

Further, the grooves 33c and 34c can also be used as grooves held by a rail for conveying the housing body 14 in a single product state when the base connector 2 is manufactured. Thereby, the alignment of the housing main body 14 when assembling the contacts 12 to the housing main body 14 can be automated.
Further, reinforcing tabs 46 and 47 are fixed to the second side wall 22 of the housing body 14. As described above, a member having a certain amount of weight is also arranged in a portion of the housing main body 14 on the side opposite to the protruding direction X11. Thereby, the load balance of the base connector 2 in the front-back direction X1 parallel to the overhang direction X11 can be improved. In addition, a reinforcing tab is disposed on the opposite side of the housing 11 where the locked end 32, the attracted portion 27, and the connecting end 38a of the lead portion 38 are concentrated. Thereby, the part of the extending direction X11 side with respect to the insertion recessed part 13 among the housings 11 does not enlarge too much, As a result, size reduction of the base connector 2 can be achieved.

  Further, after surface mounting in which the lead portion 38 of the contact 12 and the reinforcing tabs 46 and 47 are fixed to the mounting substrate 4, a tensile force may act on the housing 11 of the base connector 2 from the lock member 54 of the socket connector 3. is there. This pulling force can be received in a balanced manner at both ends of the base connector 2 in the front-rear direction X1 parallel to the protruding direction X11 by the lead portion 38 and the reinforcing tabs 46, 47. Thereby, it can suppress more reliably that the base connector 2 peels from the mounting substrate 4. FIG.

  Further, when the insertion convex portion 56 of the socket connector 3 is inserted into the insertion concave portion 13 of the base connector 2, the claw portion 70 of the lock member 54 is coupled to the locked portion 32, and the receiving portion of the lock member 54 is covered. It is received by the suction part 27. Therefore, by confirming that the receiving portion 74 of the lock member 54 is received by the attracted portion 27, it is easy and sure that the claw portion 70 and the locked portion 32 are completely coupled. I can confirm.

In addition, the receiving part 74 comes into direct contact with the attracted part 27. Thereby, it can confirm more easily and reliably that the coupling | bonding of the nail | claw part 70 and the to-be-locked part 32 is completed by the direct contact of the receiving part 74 and the to-be-adsorbed part 27. FIG.
Further, the receiving portion 74 is exposed in the protruding direction X11 in the fitted state between the socket connector 3 and the base connector 2. Thereby, it can confirm easily that the fitting of the socket connector 3 and the base connector 2 was completed by visually observing the receiving part 74 exposed to the protrusion direction X11.

In addition, when the coupling between the first claw portion 71 and the first locked portion 29 and the coupling between the second claw portion 72 and the second locked portion 31 are completed, the receiving portion 74 becomes the attracted portion 27. To come into contact. Thereby, it can be confirmed by the receiving part 74 that both the two claw parts 71 and 72 are in the locked state.
The present invention is not limited to the contents of the above embodiments, and various modifications can be made within the scope of the claims.

For example, although the first arm portion 66 and the second arm portion 67 of the lock member have been described as being connected via the lock member main body 65, the present invention is not limited to this. For example, a portion that directly connects the first arm portion 66 and the second arm portion 67 may be provided. This directly connected portion is formed in a shape that avoids the attracted portion 27 of the base connector 2.
In addition, various design changes can be made within the scope of matters described in the claims.
