In the state where 1Y is positioned below, as shown by the arrow A, the liquid resins 9X and 9Y are potted from the holes 51X and 51Y of the covers 50X and 50Y. Therefore, there is a structural limitation that the members 10X and 10Y that receive the potted resins 9X and 9Y must be disposed on the side where the connectors 1X and 1Y are located with respect to the substrates 8X and 8Y.

  In view of the above problems, an object of the present invention is to use a connector with excellent productivity and to seal a connector pin protruding from the connector housing toward the board with a small amount of resin in the connector.

Therefore, connector productivity is high. Even if there are a plurality of connector pins, the guide grooves in which the first extending portions of the connector pins are accommodated are also arranged in parallel at positions shifted in the arrangement direction. For this reason, since each lower end part of a some guide groove can be immersed in liquid resin, the connector pin sealing part can be formed in each of a some guide groove using the capillary phenomenon of liquid resin. it can.

  Such a connector manufacturing method has the following configuration. That is, a bent portion that is bent at an intermediate position in the length direction, a first extended portion that extends on one end side from the bent portion, and a second extended portion that extends on the other end side from the bent portion.

For this reason, after inserting the metal pin extending in a straight line into the pin insertion hole, the connector pin can be formed by bending one end side into the guide groove from the middle part of the metal pin. Accordingly, it is not necessary to mold the connector pins bent in advance in the mold, so that the connector productivity is high. In addition, since the first extending portion of the connector pin is disposed in the guide groove, the liquid crystal is in a liquid state up to the lower end portion where the one end side of the connector pin is positioned in the guide groove in a state where the substrate is positioned below the connector. When immersed in the resin, the liquid resin crawls up into the guide groove by capillary action. Therefore, at the time of sealing, the connector pin sealing portion that covers the second extending portion can be formed without immersing the entire second extending portion in the resin. Therefore, the amount of sealing resin is small.

  As shown in FIGS. 1, 2, 3, and 4, the connector 1 includes a plurality of connector pins 3 having one end 36 connected to the substrate 8, and a resin-made holding the connector pins 3. And a connector housing 2. In this embodiment, the connector 1 is configured as a female connector 1. For this reason, the other end side 37 of the connector pin 3 connected to the outside is located in the recess 26 formed in the connector housing 2. On the lower surface of the connector housing 2, a positioning projection 29 that fits into the hole of the substrate 8 is formed.

  In the connector 1 configured as described above, the connector pin 3 includes a bent portion 33 that is bent at an angle of 90 degrees at an intermediate position in the length direction, and a first portion that extends vertically on one end side from the bent portion 33. An extending portion 31 and a second extending portion 32 extending in the horizontal direction on the other end side from the bent portion 33 are provided.

The guide groove 21 extends in the vertical direction along the outer surface of the connector housing 2, and the pin insertion hole 22 extends in the horizontal direction so as to penetrate the connector housing 2. Accordingly, the entire pin insertion hole 22 is completely covered with the resin constituting the connector housing 2, while the guide groove 21 is in an open state with a part in the circumferential direction as a groove opening. In this embodiment, the guide groove 21 is formed in a rectangular cross section including a groove bottom portion 210 and a pair of side surface portions 211 facing each other, and a portion facing the groove bottom portion 210 is in an open state as a groove opening (FIG. 4 ( a)).

  In the connector 1 of this embodiment, a part of the guide groove 21 is formed horizontally so as to accommodate the bent portion 33 of the connector pin 3 and the second extending portion 32 in the vicinity of the bent portion 33. The guide groove 21 and the pin insertion hole 22 are connected. In the connector housing 2 configured as described above, the guide groove 21 that accommodates the first extending portion 31 of the connector pin 3 is completely open at the groove opening, but is positioned in the vicinity of the bent portion 33 in the connector pin 3. The portion that accommodates the second extending portion 32 is covered with a hook-like cover portion 27 at a portion corresponding to the groove opening (see FIGS. 1B and 4F). However, in the connector housing 2, a sufficient gap 25 is provided between the bowl-shaped cover portion 27 and the second extending portion 32 located in the vicinity of the bent portion 33 in the connector pin 3.

  In the connector 1 configured as described above, the groove bottom portion 210 of the guide groove 21 located inside the bent portion 33 of the connector pin 3 has an angular shape, and the corner portion 214 is formed by bending the connector pin 3. It becomes a fulcrum when doing (refer FIG.4 (f)). The connector pin 3 is bent at 90 ° at the bent portion 33, but the groove bottom portion 210 located inside the bent portion 33 of the connector pin 3 in the guide groove 21 of the connector housing 2 is The angled portion 214 is inclined with respect to the extending portion 31 by an angle Θ, and the corner portion 214 has an acute angle. For this reason, the first extending portion 31 of the connector pin 3 and the groove bottom portion 210 that accommodates the first extending portion 31 in the guide groove 21 form an angle of (90−Θ) ° throughout. . Therefore, a gap is formed between the first extending portion 31 of the connector pin 3 and the groove bottom portion 210 that accommodates the first extending portion 31 in the guide groove 21, and as the gap goes downward, It has spread. The angle Θ is usually set to 5 to 10 °.

  In the connector 1 of the present embodiment, the connector pins 3 are arranged in a row so that a plurality of the connector pins 3 are arranged in parallel in the horizontal direction (arrangement direction) orthogonal to the extending direction of the connector pins 3. The book connector pins 3 are arranged at positions shifted from each other. For this reason, a plurality of pin insertion holes 22 and guide grooves 21 are formed in the connector housing 2. The plurality of pin insertion holes 22 are also arranged in one row so as to be parallel in parallel in the arrangement direction of the connector pins 3, and the plurality of guide grooves 21 are also arranged in parallel so as to be parallel in the arrangement direction of the connector pins 3. Is formed. For this reason, the plurality of pin insertion holes 22 are formed at positions shifted from each other in the parallel direction, and the plurality of guide grooves 21 are also formed at positions shifted from each other in the parallel direction.

(Sealing structure and sealing method for the substrate 8)
In the manufacturing method of the connector-equipped pump device 100 according to the present embodiment, the one end side 36 of the connector pin 3 passes through the hole formed in the substrate 8 as shown in FIG. Connected by soldering. The substrate 8 is sealed with a sealing resin 9 formed by solidifying a liquid resin potted inside the partition wall 769 of the bearing holder 76.

  In this resin sealing step, when resin is potted, in this embodiment, as shown in FIG. 4 (f), the board 8 is positioned below the connector 1 and the connector pin 3 is inserted in the guide groove 21. On the other hand, the liquid sealing resin 9 is immersed to the lower end where the end side 36 is located. As a result, the liquid resin crawls up into the guide groove 21 due to a capillary phenomenon between the first extending portion 31 of the connector pin 3 and the guide groove 21. Accordingly, when the liquid resin is solidified, the sealing resin 9 is transferred to the substrate 8, the one end side 36 of the connector pin 3, and the one end side 36 of the connector pin 3 in the guide groove 21 as shown in FIG. The connector pin seal has a board sealing portion 91 in which the lower end portion where the pin is located is embedded, and extends into the guide groove 21 from the board sealing portion 91 to cover the first extension portion 31 of the connector pin 3 thinly. A stop portion 92 is provided.

  Further, a part of the guide groove 21 accommodates a bent portion 33 of the connector pin 3 and a portion located in the vicinity of the bent portion 33 in the second extending portion 32, and the capillary phenomenon also occurs in this portion. As a result, the liquid resin crawls up. Therefore, the connector pin sealing portion 92 also covers the bent portion 33 of the connector pin 3 and the portion located in the vicinity of the bent portion 33 in the second extending portion 32.

  Further, since the guide groove 21 is connected to the pin insertion hole 22, the liquid resin crawls up to the pin insertion hole 22 by a capillary phenomenon. Therefore, the connector pin sealing portion 92 also covers the portion located in the pin insertion hole 22 in the connector pin 3. However, the pin insertion hole 22 is reduced in diameter by a tapered portion 220 formed at an intermediate position, as will be described later. For this reason, the rising of the liquid resin due to the capillary phenomenon is prevented by the tapered portion 220. Therefore, the connector pin sealing portion 92 also covers the portion located in the pin insertion hole 22 in the connector pin 3, but the connector pin sealing portion 92 covers the connector pin 3 in the pin insertion hole 22. It is a part of the length direction of the connector pin 3.

  Furthermore, in the pump device 100 with a connector of this embodiment, the connector 1 includes a plurality of connector pins 3, but the plurality of connector pins 3 are shifted in the arrangement direction. For this reason, since the guide grooves 21 provided for the plurality of connector pins 3 are also shifted in the arrangement direction, all of the plurality of guide grooves 21 extend to the lower end side of the connector housing 2. Therefore, when the lower end side of the connector housing 2 is immersed in the liquid resin, the liquid resin creeps up in any of the plurality of guide grooves 21. Therefore, all of the plurality of connector pins 3 are covered with the connector pin sealing portion 92.

(Manufacturing method of connector 1)
In order to manufacture the connector 1 of this embodiment, first, the connector housing 2 provided with the pin insertion holes 22 and the guide grooves 21 is molded with resin. On the other hand, as a metal pin for configuring the connector pin 3, a metal pin extending in a straight line is prepared.

  Then, after inserting a metal pin extending linearly into the pin insertion hole 22, the connector pin 3 is formed by bending one end side 36 into the guide groove 21 from the middle part of the metal pin at 90 °.

  When performing such bending, the corner portion 214 of the guide groove 21 located inside the bent portion 33 of the connector pin 3 is bent at an acute angle. For this reason, if the metal pin is bent at an angle deeper than 90 °, even if the first extending portion 31 attempts to return to its shape by the springback, the first extending portion 31 and the second extending portion 32 are used. The angle formed by can be 90 °.

  In addition, when the metal pin is bent, the connector housing 2 has a wide gap 25 around the bent portion 33. Therefore, a tool such as a jig for bending the metal pin or a tool such as a chuck is used for bending the metal pin. Can be inserted deeply.

  Furthermore, in this embodiment, even if there are a plurality of connector pins 3, the connector pins 3 are displaced in the arrangement direction. For this reason, when the connector pin 3 is bent, the other connector pins 3 do not get in the way.

  In adopting such a manufacturing method, in this embodiment, as shown in FIG. 4 (f), of the both ends of the pin insertion hole 22, the end on the side where the guide groove 21 is located is set to the outer diameter of the metal pin. The taper surface 220 is formed so as to be narrower than the pin insertion hole 22 in the middle of the pin insertion hole 22. Therefore, as indicated by the arrow B, it is easy to insert the metal pin into the pin insertion hole 22, and high accuracy can be obtained at the protruding position of the other end 37 of the metal pin.

  In addition, a metal pin in which a plurality of metal pins are connected via a narrow diameter portion is used, and before the metal pin is inserted into the pin insertion hole 22 or after being inserted into the pin insertion hole 22, If the pins are divided, the productivity of the connector 1 can be increased.

(Main effects of this form)
As described above, in the connector-equipped pump device 100 and the manufacturing method thereof according to the present embodiment, the connector 1 includes the bent portion 33 where the connector pin 3 is bent at an intermediate position in the length direction, and one end side from the bent portion 33. 36, and a second extending portion 32 extending on the other end side 37 from the bent portion 33, and the connector housing 2 has the second extending portion 32 inserted therein. A pin insertion hole 22 and a guide groove 21 in which the first extending portion 31 is accommodated are provided. For this reason, after inserting the linearly extending metal pin into the pin insertion hole 22, the connector pin 3 can be formed by bending one end side 36 into the guide groove 21 from the middle part of the metal pin. . Accordingly, it is not necessary to mold the connector pins 3 bent in advance in the mold, so that the productivity of the connector 1 is high.

  Further, since the first extending portion 31 of the connector pin 3 is disposed in the guide groove 21, one end side of the connector pin 3 in the guide groove 21 with the substrate 8 positioned below the connector 1. When immersed in the liquid resin up to the lower end where the 36 is located, the liquid resin crawls up into the guide groove 21 by capillary action. Therefore, at the time of sealing, the connector pin sealing portion 92 covering the second extending portion 32 can be formed without immersing the entire second extending portion 32 in the resin. Therefore, the amount of the sealing resin 9 can be small.

  In the connector 1 of this embodiment and the manufacturing method thereof, even if there are a plurality of connector pins 3, the connector pins 3 are displaced in the arrangement direction. Therefore, when the connector pins 3 are bent, other connector pins 3 does not get in the way. Therefore, the productivity of the connector 1 is high.

  Even if there are a plurality of connector pins 3, the guide grooves 21 in which the first extending portions 31 of the connector pins 3 are accommodated are also arranged in parallel at positions shifted in the arrangement direction. For this reason, since each lower end part of the some guide groove 21 can be immersed in liquid resin, the connector pin sealing part 92 is formed in each of the some guide groove 21 using the capillary phenomenon of liquid resin. can do.
