  As described above, for example, a coating material for preventing corrosion is used for the connection terminals of the connector mounted on the printed board, and a film formation process (coating process) is performed by a PVD method (for example, sputtering). Generally, a coating process is performed only to the connection part fixed to a printed circuit board among connection terminals. On the other hand, the terminal portion of the connector that contacts the mating connector (mating terminal) is masked to prevent electrical contact failure.

  However, in the technique described in Patent Document 1 described above, it is necessary to remove the suction auxiliary tool after the connector is sucked and transported on the printed circuit board, and to perform a masking process for the terminal portion separately in order to perform the coating process. . Further, such masking processing has been performed by a technique in which an operator manually applies a masking tape. Furthermore, after the coating process, for example, an operator had to manually remove the masking tape. For this reason, there has been a problem that much labor and time are required for the coating process and the masking process. In addition, in order to accurately perform masking processing at an appropriate position of the connection terminal, there is a problem that skill of an operator is required.

That is, the taper surface 45 of each protrusion 42 is located above the taper surfaces 44 (44a, 44b).

  Next, a procedure for attaching the cover 1 to the plug connector 2, that is, a procedure for forming the plug connector 3 with a cover will be described. The forming operation of the plug connector with cover 3 is automatically or manually performed by a robot or an operator (hereinafter referred to as “operator etc.”). In the following description, it is assumed that the plurality of connection terminals 11 and the pair of connection fittings 12 are held by the housing 10 and the plug connector 2 is configured.

  First, as shown in FIG. 1, for example, an operator places the cover 1 over the plug connector 2. Subsequently, the cover 1 is moved downward with respect to the plug connector 2, and the plug connector 2 is fitted to the mask holding portion 31 of the cover 1. Specifically, the fitting convex portion 43 of the mask holding portion 31 is caused to enter the concave space 16 of the plug connector 2, and each housing side wall 14 and each housing end wall 15 of the plug connector 2 are connected to the mask holding portion 31. The container 41 is made to enter.

  At this time, when the plug connector 2 and the cover 1 are slightly displaced from front to back and from side to side, first, each housing end wall 15 (each connection fitting 12) of the plug connector 2 is formed in the accommodating portion 41. It abuts on the second tapered surface 44b. The plug connector 2 enters the accommodating portion 41 while being guided by the second tapered surfaces 44b. As the plug connector 2 advances, each housing side wall 14 (each connection terminal 11) of the plug connector 2 has a first tapered surface 44 a formed in the accommodating portion 41 and a convex portion formed in the fitting convex portion 43. Abuts against the tapered surface 46. The plug connector 2 further enters the accommodating portion 41 while being guided by the first tapered surfaces 44a and the convex side tapered surface 46.

  As the plug connector 2 further advances, the outer peripheral side surface of the plug connector 2 starts to slidably contact the plurality of protrusions 42 formed in the housing portion 41. Specifically, the four protrusions 42 formed on the center side in the left-right direction on both the front and rear inner surfaces of the housing part 41 are in contact with the housing side walls 14. Since these protrusions 42 are in sliding contact with the resin housing side wall 14 while avoiding the metal connection terminals 11, for example, the protrusions 42 are prevented from being scraped to prevent resin pieces (shavings) from being generated. be able to. Further, the four protrusions 42 formed on both the left and right direction inner sides of the housing part 41 and the four protrusions 42 formed on both the inner surfaces of the left and right direction are held by the housing end walls 15. The contact fitting 12 is in contact with the smooth side surface. It should be noted that the four protrusions 42 formed on both the left and right ends on both inner sides in the front-rear direction are in contact with the outer sides in the left-right direction avoiding the notches 12 a of the connection fitting 12. Since these protrusions 42 are in sliding contact with the smooth side surface of the connection fitting 12, it is possible to prevent the generation of resin pieces (shavings) as described above.

  As shown in FIG. 5, the upper end surface of each housing side wall 14 (each connection terminal 11) comes into contact with the lower surface of the mask body 32 (the top surface of the housing portion 41), so that the plug connector 2 with respect to the housing portion 41. Entry stops. As a result, the plug connector 2 is pressed into the mask holding portion 31 of the cover 1. That is, the cover-attached plug connector 3 is completed.

  As described above, the plurality of protrusions 42 are brought into pressure contact with the housing 10 or the like in the housing portion 41, so that the mask portion 30 is positioned on the plug connector 2 (housing 10) via the mask holding portion 31. Held in. That is, the masking of each connection terminal 11 (each terminal part 20) by the mask part 30 can be completed only by relatively press-fitting the mask holding part 31 into the housing 10. Further, when the plug connector 2 is press-fitted into the accommodating portion 41, even if the plug connector 2 and the cover 1 are slightly displaced, they are guided by the tapered surfaces 44a, 44b, 46 so that the cover 1 is appropriately Moved to the correct position. Thereby, the press-fit of the plug connector 2 (housing 10) to the mask holding part 31 (accommodating part 41) can be smoothly performed.

  In this state, the outer terminal portion 22 of each terminal portion 20 faces into the accommodating portion 41 and is completely covered by the cover 1 (mask body 32). Moreover, the connection part 21 of each connection terminal 11 is extended toward the front-back direction outer side from each groove part 34 by planar view (refer FIG. 3). Each connection portion 21 is partially covered by the mask body 32 and part of the outside is exposed. The outer end portion of each connection portion 21 is located on the outer side in the front-rear direction than each convex portion 35. In the first embodiment, the distance from the outer surface of each groove 34 to the outer tip of the connecting portion 21 is set to 0.16 mm, for example. In addition, it is preferable that about half of the length of the connection part 21 is exposed.

  Further, the notch portion 12a of each connection fitting 12 faces the accommodating portion 41 and is completely covered by the cover 1 (mask end portion 33). And only the lower part is exposed rather than the notch part 12a of each connection metal fitting 12. As shown in FIG.

  Further, in this state, a gap G is formed between the lower surface of the mask body 32 and the upper surface of the connection portion 21 of each connection terminal 11 (see FIG. 5). An opening 47 is formed in (a part of) the gap G so as to expand outward in the incident direction of the coating material in the coating process performed by the PVD method. The openings 47 are respectively formed in a plurality of main body side openings 47a (see FIG. 5) constituted by the main body opening inclined surfaces 36 formed in the plurality of convex portions 35 and the pair of mask end portions 33, respectively. A pair of front and rear metal fitting side openings 47b (two sets on the left and right sides) (see FIG. 6) constituted by each connection inclined surface 37, each first opening inclined surface 38, and each second opening inclined surface 39. .

  The cover-attached plug connector 3 configured as described above is accommodated in a plurality of pockets 101 recessed in the embossed carrier tape 100 and sealed with a film 102, as shown in FIG. Each cover-attached plug connector 3 is packed in the embossed carrier tape 100 with the cover 1 facing the opening side of the pocket 101. The embossed carrier tape 100 that houses the plurality of plug connectors 3 with covers is shipped in a wound state.

  Next, the procedure for mounting the plug connector with cover 3 on the substrate S1 will be described. The wound embossed carrier tape 100 is rotatably mounted on a reel device (not shown).

  The embossed carrier tape 100 is fed out of the reel device with the opening of the pocket 101 facing upward. Note that the embossed carrier tape 100 is fed out while removing the film 102. The plug connector with cover 3 accommodated in the pocket 101 is sucked and conveyed onto the substrate S1 by a robot such as a chip mounter. Specifically, the robot sucks the suction surface 40 of the cover 1 using its own suction disk, takes out the plug connector 3 with cover from the pocket 101, and places the plug connector 3 with cover at a predetermined position on the substrate S1. Move to. The robot releases the suction after the plug connector with cover 3 is arranged at a predetermined position on the substrate S1.

  Cream solder is applied to a predetermined position on the substrate S1, and each connection terminal 11 and each connection fitting 12 of the plug connector 3 with cover are soldered on the substrate S1 by heating. Thereby, the plug connector 3 with the cover is mounted on the substrate S1 (see FIG. 4 and the like). In addition, since the connection part 21 of each connection terminal 11 is exposed from each groove part 34 of the mask part 30, the state mounted in board | substrate S1 can be confirmed visually or with an inspection camera. Thereby, it is possible to inspect for the presence or absence of attachment failure of the plug connector 2 on the substrate S1.

  Next, a coating process for preventing corrosion by the PVD method is performed on the component including the substrate S1 and the plug connector 3 with the cover mounted on the substrate S1. Here, for example, the coating process is performed by sputtering. First, the operator sets the substrate S1 on which the plug connector with cover 3 and the like are mounted on a sputtering apparatus (not shown). In the sputtering apparatus, since the ionized coating material jumps out with various directions, the coating process is performed while rotating the substrate S1 at various angles. For example, a thin film made of a coating material while rotating the substrate S1 (plug connector 3 with cover) in one direction (see the solid line arrow in FIGS. 4 and 5) around a rotation axis A (see FIG. 4) extending in the left-right direction. Is formed.

  By the way, paying attention to each connection terminal 11, this coating process is performed only on the lower part of each connection part 20 and each connection metal fitting 12 fixed to the board | substrate S1. The coating process is not performed on each terminal portion 20 and the notch portion 12a of each connection fitting 12 in order to appropriately ensure electrical connection with each socket-side terminal 51 and the like. In this respect, in the plug connector 3 with cover, since the terminal portion 20 of each connection terminal 11 and the notch portion 12a of each connection fitting 12 are covered with the cover 1, formation of a thin film with a coating material for each terminal portion 20 is performed. Is blocked.

  On the other hand, since a part of the connection part 21 of each connection terminal 11 is exposed to the outside from each groove part 34, the coating material is allowed to adhere to the exposed part of each connection part 21. That is, the ionized coating material passes through the groove portions 34 from above the mask body 32 (see the broken line arrows in FIG. 5) and adheres to the exposed portions of the connection portions 21 to form a thin film. In addition, since there is a slight gap between the left and right side surfaces of each connecting portion 21 and each groove portion 34 in plan view (see FIG. 3), the both right and left side surfaces of each connecting portion 21 are also appropriate. A thin film can be formed.

  Further, since gaps G are formed between the mask main body 32 and the respective connecting portions 21, ionized coating material flying with a predetermined direction can be transferred from the gap G to the inside of the mask main body 32. (See the dashed arrow in FIG. 5). Further, since the main body side opening 47a is formed in each convex portion 35, the ionized coating material incident obliquely toward the gap G can easily enter the inside of the mask main body 32 without being blocked. (See the broken line arrow in FIG. 5). Thereby, a thin film can be appropriately formed also in the part covered with the mask main body 32 of each connection part 21. FIG.

  Similarly, the ionized coating material can enter the inside of each mask end 33 from the gap G (see the dashed arrow in FIG. 6). In addition, since a pair of front and rear metal-side openings 47b are formed in each mask end portion 33, the ionized coating material incident obliquely toward the gap G is not obstructed and is not blocked. It is possible to enter inside (see broken line arrow in FIG. 6). Thereby, a thin film can be appropriately formed in the lower part of each connection fitting 12 covered with each mask end 33. Each metal part opening 47b also contributes to film formation of each connection part 21 located at both ends in the left-right direction.

  After the coating process is completed, the operator takes out the substrate S1 from the sputtering apparatus and removes the cover 1 from the plug connector 3 with a cover. At this time, an operator hooks a finger or a jig on the handle portion 33a formed on the pair of left and right mask ends of the cover 1 and removes the cover 1 upward. Thereby, the cover 1 can be easily removed from the plug connector 2. Thus, the coating process for the plug connector 2 mounted on the substrate S1 is completed.

  According to the cover 1 according to the first embodiment described above, the mask portion 30 is in a state in which a part of each connection portion 21 is exposed only by relatively press-fitting the mask holding portion 31 into the housing 10. It is hold | maintained at the housing 10 so that the terminal part 20 as an uncoated part may be covered. Thereby, the appropriate position of each connection terminal 11 can be masked easily and accurately. In addition, since the gap G is formed between the mask portion 30 and each connection portion 21, the coating material can be attached to the unexposed portions of each connection portion 21. Moreover, since each terminal part 20 is connected with each connection part 21 at a different angle (approximately 90 °) so as not to be parallel, the coating material that has passed through the gap G may adhere to each terminal part 20. Is prevented. Thereby, it is possible to coat substantially the entire side surface, upper surface, and end surface of each connection portion 21 while appropriately masking each terminal portion 20. Such a configuration of the cover 1 is particularly effective when performing film formation (surface modification) by sputtering, such as PVD processing. The coating process may be performed by a method such as plasma CVD (chemical vapor deposition).

  Further, according to the cover 1 according to the first embodiment, each connection portion 21 can be exposed from the mask portion 30 in the groove portion 34 that is recessed at a position corresponding to each connection portion 21. Thereby, each connection part 21 can be coated appropriately. Moreover, since the mask part 30 has the flat adsorption | suction surface 40 on the opposite side to the plug connector 2 side, the adsorption | suction surface 40 can be adsorb | sucked appropriately by the suction disk of a robot, for example. Thus, the plug connector 2 can be sucked and conveyed onto the substrate S1 through the cover 1. In addition, after the plug connector with cover 3 is arranged and mounted on the substrate S1, the process can be shifted to the coating process as it is. Thereby, the masking process process of the plug connector 2 (each terminal part 20) performed at the time of a coating process can be skipped.

Yes. In the suction surface 76, a substantially rectangular recess 76a that is long in the front-rear direction is recessed in the upper surface portion of each socket-side mask end portion 73 in order to prevent so-called shrinkage during integral molding.

  As shown in FIG. 9, the socket-side mask holding portion 71 includes a pair of convex wall portions 80 and a pair of fitting blocks 81 that can enter a socket-side concave space 56 (concave portion) formed in the socket-side housing 50. And a plurality of socket-side protrusions 82 formed on the side surfaces of the wall portions 80 and the fitting blocks 81 and press-contactable with the socket-side housing 50.

  Each wall portion 80 has a substantially plate shape elongated in the left-right direction, and is suspended from the lower surface of the socket-side mask main body 72. The wall portions 80 are provided in parallel in the front-rear direction so as to correspond to the socket-side concave space 56. Each wall portion 80 extends to a position below the central protrusion 62a (or the inner protrusion 63a) of the socket-side terminal portion 60 in a state where the socket-side cover 4 is covered with the socket connector 5. For example, the height of each wall 80 is formed to be approximately half the depth of the socket-side concave space 56 (see FIG. 12).

  Each fitting block 81 has a substantially rectangular parallelepiped shape that is long in the front-rear direction, and is suspended from the lower surface of the socket-side mask end 73. The lower end of each fitting block 81 is located below the lower end of each wall part 80 (refer FIG. 13). Each fitting block 81 has a gap between both end portions of each wall portion 80 in the left-right direction, and is formed between the central socket-side housing protruding wall 54b and each socket-side housing end wall 55. In order to correspond to the socket-side concave space 56, they are provided in parallel in the left-right direction. The pair of recesses 76a described above is formed so as to enter the fitting block 81 from the socket side mask end 73 side.

  The plurality of socket side protrusions 82 are provided so as to protrude from both side surfaces in the front-rear direction of each wall 80 and both side surfaces in the left-right direction of each fitting block 81. Four socket-side protrusions 82 are arranged at predetermined intervals on both side surfaces of each wall 80 in the front-rear direction, and each socket-side protrusion 82 extends from the lower surface of the socket-side mask body 72 to each wall. It is long in the vertical direction to the vicinity of the lower end of the portion 80. Two socket-side protrusions 82 are disposed in the front-rear direction on both side surfaces of each fitting block 81 in the front-rear direction, and each socket-side protrusion 82 is a block-side taper described later from the lower surface of the end body 74. The upper end of the surface 85 is long in the vertical direction. In addition, the lower end position of each socket side projection part 82 is formed so that it may become the same position, respectively.

  As shown in FIG. 9, a taper surface 83 for guiding the press-fitting of the housing 10 is respectively provided at the lower end of each wall 80 (the front end in the press-fitting direction of the socket connector 5) and the lower end of each socket-side protrusion 82. 84 is formed. Similarly, a block-side tapered surface 85 is also formed on the entire peripheral edge at the lower end of each fitting block 81.

  As shown in FIG. 13, since the lower end part of each wall part 80 has a substantially semicircular cross section, the wall side taper surface 83 of each wall part 80 is formed as a substantially circumferential surface. The wall side tapered surface 83 may be formed as a flat surface. The taper surface 84 of each socket-side protrusion 82 is formed on the upper side (base end side) of the lower end portion (front end portion in the press-fitting direction) of each wall portion 80. That is, the taper surface 84 of each socket-side protrusion 82 is located above the wall-side taper surface 83.

  Next, a procedure for attaching the socket side cover 4 to the socket connector 5, that is, a procedure for forming the socket connector 6 with a cover will be described.

  First, as shown in FIG. 8, for example, the worker or the like faces the socket-side cover 4 above the socket connector 5 and moves the socket-side cover 4 downward with respect to the socket connector 5. The wall portions 80 and the fitting blocks 81 of the socket-side mask holding portion 71 are caused to enter the socket-side concave space 56 of the socket connector 5, and the socket-side housing protruding wall 54 b of the socket connector 5 is connected to the wall portions 80 and 80. A central space surrounded by each fitting block 81 is entered.

  At this time, when the socket connector 5 and the socket-side cover 4 are slightly displaced from front to back and left and right, first, the block-side taper surface 85 of each fitting block 81 is inserted into the socket of each socket-side housing end wall 55. The socket side cover 4 abuts on the side taper surface 55 b and enters the socket side concave space 56 while being guided by the taper surfaces 55 and 85. As the socket-side cover 4 advances, each wall portion 80 is guided by its own wall-side tapered surface 83 and enters the substantially U-shaped socket-side terminal portion 60.

  When the socket-side cover 4 further advances, the inner peripheral side surface of the socket connector 5 starts to slidably contact the plurality of socket-side protrusions 82 formed on each wall 80 and each fitting block 81. Specifically, the four socket-side protrusions 82 (two sets of front and rear) formed on the outer side in the front-rear direction of each wall 80 are in contact with the inner side surfaces of the pair of front and rear socket-side housing side walls 54a. Similarly, the four socket-side protrusions 82 (two sets of front and rear) formed on the inner side in the front-rear direction of each wall 80 are in contact with both side surfaces of the socket-side housing protruding wall 54b in the front-rear direction. That is, each socket-side protrusion 82 formed on each wall 80 comes into pressure contact with each socket-side housing side wall 54 a and socket-side housing protruding wall 54 b exposed between the socket-side terminal 51 and the socket-side terminal 51. Further, the two socket side projections 82 (two sets of left and right) formed on the outer side in the left and right direction of each fitting block 81 are in contact with the inner side surfaces of the pair of left and right socket side housing end walls 55. Similarly, the two socket-side protrusions 82 (two sets of left and right) formed on the inner side in the left-right direction of each fitting block 81 are in contact with the left and right side surfaces of the socket-side housing protruding wall 54b. As described above, since each socket-side protrusion 82 is in sliding contact with the resin-made socket-side housing 50, for example, generation of resin pieces (shavings) of the socket-side protrusion 82 can be prevented.

  11 and FIG. 12, the upper end surfaces of the socket side housing side walls 54a and the socket side housing protruding walls 54b abut against the lower surface of the socket side mask body 72, and The end surface comes into contact with the lower surface of the end main body 74 of the socket side mask end 73, so that the entry of the socket side cover 4 into the socket side concave space 56 is stopped. As a result, the socket connector 5 is pressed into the socket-side mask holding portion 71 of the socket-side cover 4. That is, the socket connector 6 with a cover is completed. The pair of left and right vertical wall portions 75 respectively cover the upper part of the outer side surface in the left-right direction of the socket-side housing end wall 55.

  Thus, the masking of the socket side terminal 51 by the socket side mask part 70 can be completed only by relatively press-fitting the socket side mask holding part 71 into the socket side housing 50. Further, when the socket-side mask holding portion 71 is press-fitted into the socket-side housing 50, even if the socket connector 5 and the socket-side cover 4 are slightly displaced, they are guided by the tapered surfaces 83 and 84, The socket side cover 4 is moved to an appropriate position. Thereby, the socket side mask holding part 71 can be smoothly pressed into the socket side concave space 56 of the socket side housing 50.

  In this state, the horizontal portion 65 of each socket side terminal 51 is covered with the socket side mask main body 72, and the vertical portion 66 and the fixing portion 67 of each socket side terminal 51 are exposed to the outside (FIGS. 10 and 10). 11). Further, the pair of front and rear rectangular metal fittings 68 of each socket side metal fitting 52 are respectively exposed to the outside in the front and rear direction from the rectangular holding portion 58a of the socket side housing end wall 55 (see FIG. 11). Since the socket side terminal 51 is held one step down from the surface of the socket side housing side wall 54a, the socket side terminal 51 is interposed between the lower surface of the socket side mask body 72 and the upper surface of the horizontal portion 65 of each socket side connection portion 61. A slight gap C is formed (see FIG. 12).

  The cover-attached socket connector 6 configured as described above is packed in the embossed carrier tape 100 in the same manner as the cover-attached plug connector 3 according to the first embodiment. And the socket connector 6 with a cover is mounted in the board | substrate S2 in the procedure similar to the plug connector 3 with a cover which concerns on 1st Embodiment (refer FIG. 11 etc.). The description of the procedure for mounting the socket connector with cover 6 on the substrate S2 is omitted.

  In addition, the coating process (for example, sputtering) is performed on the board S2 and the socket connector 6 with the cover mounted on the board S2, similarly to the plug connector 3 with the cover according to the first embodiment. For example, thin film formation is performed while rotating the substrate S1 and the like in one direction (see solid line arrows in FIGS. 11 and 12) around a rotation axis A ′ (see FIG. 11) extending in the left-right direction. Considering the socket connector 6 with cover, since the socket side terminal portion 60 of each socket side terminal 51 and the contact portion 68a of each socket side metal fitting 52 are covered with the socket side cover 4, each socket side terminal portion 60 and Formation of a thin film by the coating material on each contact portion 68a is prevented.

  On the other hand, in the socket side connection portion 61 of each socket side terminal 51, the vertical portion 66 and the fixing portion 67 are exposed to the outside, so that a thin film made of a coating material is formed on each vertical portion 66 and the fixing portion 67. Is done. Similarly, a thin film made of a coating material is also formed on the pair of front and rear rectangular metal fittings 68 of each socket-side metal fitting 52. Note that the ionized coating material flying with a predetermined direction may enter the inside of the socket side mask body 72 from the gap C (see the broken line arrow in FIG. 12). For this reason, a thin film is also formed on each horizontal portion 65 covered with the socket-side mask body 72.

  Note that the ionized coating material that has entered the inside of the socket-side mask main body 72 from the gap C abuts on each wall portion 80 that extends downward from the central protrusion 62a (see FIG. 12). Thereby, it can prevent effectively that the coating material which has passed the gap | interval C adheres to the center terminal part 62 of each socket side terminal part 60, for example.

  After the coating process is completed, the operator takes out the substrate S2 from the sputtering apparatus and hooks a finger or a jig on the handle portion 75b formed on the vertical wall portion 75 of the pair of left and right socket side mask ends 73, Remove the cover 1 upward. Thus, the coating process for the socket connector 5 mounted on the substrate S2 is completed.

  According to the socket side cover 4 according to the second embodiment described above, the same effects as those of the cover 1 according to the first embodiment described above can be obtained.

  In addition, although the socket side cover 4 (socket side mask part 70) which concerns on 2nd Embodiment was formed slightly narrowly in the front-back direction rather than the socket side housing 50, this invention is not limited to this. For example, the front-rear width of the socket-side cover 4 may be set so as to cover each fixing portion 67 when viewed from above with the socket-side cover 4 attached to the socket connector 5. In this case, similarly to the plurality of grooves 34 described in the first embodiment, it is preferable to form a plurality of grooves (not shown) on both side surfaces in the front-rear direction of the socket-side mask main body 72. In this case, the lower portion of the socket-side mask main body 72 in the front-rear direction outer side surface (convex portion between adjacent groove portions) may be chamfered and inclined.

  In addition, although each handle part 33a, 75b was dented in the left-right direction both outer side surface of the mask parts 30 and 70, you may provide so that it may protrude outside. Moreover, you may provide in the front-back direction both outer side surface of the mask parts 30 and 70. FIG.
