Disclosure of Invention
Problems to be solved by the invention
In the two positioning pins of the connector disclosed in patent document 1, one of the two positioning pins has a circular cross section, and the other one has a shape that is longer in the front-rear direction than the width direction of the housing. Therefore, if a through hole long in the front-rear direction is formed in the circuit board and another square pin is inserted into the through hole, the positions where both side surfaces of the other square pin contact the inner side surfaces of the through hole in the width direction are stable. Therefore, positioning in the width direction can be performed with high accuracy. However, in the front-rear direction, the contact position is difficult to stabilize.
Accordingly, the present disclosure aims to improve reliability of positioning of a connector with respect to a circuit substrate.
Means for solving the problems
The connector of the present disclosure is provided to a circuit board, and the connector includes a housing having an opposing surface opposing the circuit board, a1 st protrusion protruding from the opposing surface, and a2 nd protrusion protruding from the opposing surface with a space from the 1 st protrusion, wherein the 1 st protrusion has a1 st positioning portion disposed in a1 st through hole of the circuit board, the 2 nd protrusion has a2 nd positioning portion disposed in a2 nd through hole of the circuit board, and when an X direction and a Y direction orthogonal to the X direction are set to a surface direction parallel to the opposing surface, the 1 st positioning portion has a shape longer in the X direction than the Y direction, and the 2 nd positioning portion has a shape longer in the Y direction than the X direction.
Effects of the invention
According to the present disclosure, the reliability of positioning of the connector with respect to the circuit substrate can be improved.

The connector has a1 st positioning portion long in the X direction and a2 nd positioning portion long in the Y direction. Therefore, the reliability of the positioning in the Y direction can be improved by the 1 st positioning portion, and the reliability of the positioning in the X direction can be improved by the 2 nd positioning portion. Therefore, according to the connector, the reliability of positioning with respect to the circuit board can be improved.
(2) Preferably, the mounting member is provided with a mounting portion for mounting the housing on the circuit board, the mounting portion is mounted on the housing, the insertion portion protrudes to the same side as the 1 st protrusion and the 2 nd protrusion, and the insertion portion has a joint portion arranged in the joint hole of the circuit board.
Even if the circuit board is deformed by bending by heating or the like at the time of reflow soldering, the joint portion can be displaced in the joint hole according to the deformation of the circuit board. Therefore, a large stress is not applied to the joint.
(3) Preferably, the case has a spacer portion that forms a gap between the opposing surface and the circuit board in a state of being mounted on the circuit board.
According to this connector, a gap is formed between the opposing surface of the housing and the circuit board in a state where the housing is mounted on the circuit board. Therefore, even if the circuit board is deformed by bending by heating or the like at the time of reflow soldering, the circuit board is not in contact with the opposing surface of the case, and is not subjected to a reaction force from the opposing surface side. As a result, the force for deforming the circuit board can be suppressed from being transmitted from the opposing surface of the case to the 1 st projection and the 2 nd projection, and no unnecessary stress can be generated in the 1 st projection and the 2 nd projection.

The 2 nd short side inner surface 85 forms the front and rear sides of the inner peripheral surface of the 2 nd through hole 82. The 2 nd short side inner surface 85 has a curved surface shape with a central portion extending outward in the front-rear direction. The 2 nd long side inner surface 86 forms the left and right sides of the inner peripheral surface of the 2 nd through hole 82. The 2 nd long side inner surface 86 is planar.
The circuit substrate 80 has an engagement hole 87 and a hole 88. The engagement portion 74 is disposed in the engagement hole 87. The substrate connection portion 22 of the terminal fitting 15 and the grounding portion 28 of the outer conductor 17 are disposed in the hole 88.
Hereinafter, a method of assembling the connector 10 and a method of mounting the connector on the circuit board 80 will be described. First, the pair of terminal members 15 are fitted into the 1 st fitting hole 25 of the dielectric body 16. Then, the pair of terminal members 15 mounted on the dielectric body 16 are disposed inside the outer conductor 17. Thus, the terminal module 12 is manufactured. The terminal module 12 is fitted into the 2 nd fitting hole 32 of the housing 11. The 1 st mounted portion 71 and the 2 nd mounted portion 72 of the mounting member 13 are mounted on the mounting portion 60 of the housing 11. More specifically, the 1 st mounted portion 71 and the 2 nd mounted portion 72 are press-fitted into the mounting groove 61 of the mounting portion 60 from above. Thus, the connector 10 is manufactured.
Solder paste is applied to the joint holes 87 and 88 of the circuit board 80 in advance. The 1 st projection 40 is inserted into the 1 st through hole 81. The 2 nd protrusion 50 is inserted into the 2 nd penetration hole 82. The insertion portion 73 of the fitting member 13 is inserted into the engagement hole 87. As shown in fig. 7 and 8, the connector 10 is mounted on a circuit board 80. The connector 10 is carried on the circuit board 80 in the following state.
As shown in fig. 7 and 9, the 1 st positioning portion 40B is disposed at the center in the 1 st through hole 81. The 1 st short side surfaces 42 on the left and right sides of the 1 st positioning portion 40B are opposed to the 1 st short side inner surface 83, and the 1 st long side surfaces 43 on the front and rear sides are opposed to the 1 st long side inner surface 84. There is no gap or little if any gap between the 1 st positioning portion 40B and the 1 st long side inner surface 84 on the front and rear sides. Therefore, the 1 st positioning portion 40B performs positioning in the front-rear direction. A gap in which the 1 st positioning portion 40B is displaceable is formed between the 1 st positioning portion 40B and the 1 st short side inner surfaces 83 on the left and right sides. Hereinafter, the left gap among the gaps is referred to as a1 st space 91, and the right gap is referred to as a2 nd space 92. The width of the 1 st space 91 and the 2 nd space 92 in the left-right direction is larger than the width of the gap between the 1 st positioning portion 40B and the 1 st long side inner surface 84 on the front-rear side in the front-rear direction.
As shown in fig. 7 to 9, the 2 nd positioning portion 50B is disposed at the center in the 2 nd through hole 82. The 2 nd short side surfaces 52 on the front and rear sides of the 2 nd positioning portion 50B are respectively opposed to the 2 nd short side inner surfaces 85, and the 2 nd long side surfaces 53 on the left and right sides are respectively opposed to the 2 nd long side inner surfaces 86. There is no gap or little if any gap between the 2 nd positioning portion 50B and the 2 nd long side inner surfaces 86 on the left and right sides. Therefore, the positioning in the left-right direction is performed by the 2 nd positioning portion 50B. A gap in which the 2 nd positioning portion 50B can be displaced is formed between the 2 nd positioning portion 50B and the 2 nd short side inner surfaces 85 on the front and rear sides. Hereinafter, the gap on the front side of the gap is referred to as a3 rd space 93, and the gap on the rear side is referred to as a4 th space 94. The width of the 3 rd space 93 and the 4 th space 94 in the front-rear direction is larger than the width of the gap between the 2 nd positioning portion 50B and the 2 nd long side inner surfaces 86 on the left and right sides in the left-right direction.
The 1 st short side surface side isolation portion 44, the 1 st long side surface side isolation portion 45, the 2 nd short side surface side isolation portion 54, the 2 nd long side surface side isolation portion 55, the 3 rd isolation portion 57, and the 4 th isolation portion 58 of the connector 10 are carried on the circuit board 80. Thereby, a gap is formed between the facing surface 33 and the circuit board 80.
The connector 10 carried on the circuit substrate 80 is subjected to a reflow process. Thus, the connector 10 is soldered to the circuit board 80, and the board-with-connector 100 including the connector 10 and the circuit board 80 is manufactured (see fig. 7 and 8).
In the stage before the reflow process, the circuit board 80 is not fixed in the vertical direction with respect to the connector 10. Therefore, when the reflow process is performed on the circuit board 80, there is a possibility that the circuit board may warp in the up-down direction due to heating as shown in fig. 10 to 13. When the circuit board 80 is warped, the 1 st positioning portion 40B and the 2 nd positioning portion 50B may be deformed by an external force from the circuit board 80 that is bent and deformed. However, a1 st space 91 and a 2 nd space 92 are formed between the 1 st positioning portion 40B and the 1 st short side inner surfaces 83 on the left and right sides.
Even if the left and right central portions of the circuit board 80 are deformed so as to be bent upward as shown in fig. 10 and 11, the 1 st positioning portion 40B moves in the 1 st space 91 or the 2 nd space 92, so that it is possible to avoid receiving an external force in the left and right direction from the circuit board 80. In addition, even if an external force in the left-right direction from the circuit board 80 is applied to the 2 nd positioning portion 50B, the 2 nd long side surface 53 of the 2 nd positioning portion 50B and the 2 nd long side inner surface 86 are in contact in the front-rear long region, and thus the stress is dispersed.
As shown in fig. 12 and 13, even if the front-rear central portion of the circuit board 80 is deformed so as to be bent upward, the 2 nd positioning portion 50B moves in the 3 rd space 93 or the 4 th space 94, and thus, it is possible to avoid receiving an external force in the front-rear direction from the circuit board 80. Even if an external force is applied to the 1 st positioning portion 40B in the front-rear direction from the circuit board 80, the 1 st long side surface 43 of the 1 st positioning portion 40B and the 1 st long side inner surface 84 are in contact in the left-right long region, so that the stress is dispersed.
Further, gaps are formed between the opposing surface 33 and the circuit board 80 by the 1 st short-side surface-side isolation portion 44, the 1 st long-side surface-side isolation portion 45, the 2 nd short-side surface-side isolation portion 54, the 2 nd long-side surface-side isolation portion 55, the 3 rd isolation portion 57, and the 4 th isolation portion 58. Therefore, even if the circuit board 80 is deformed by bending due to overheating or the like at the time of reflow soldering, the circuit board can be prevented from being brought into contact with the opposing surface 33 of the case 11 and receiving a reaction force from the opposing surface 33. As a result, the force for deforming the circuit board 80 can be suppressed from being transmitted from the facing surface 33 of the housing 11 to the 1 st positioning portion 40B and the 2 nd positioning portion 50B, and no unnecessary stress can be generated in the 1 st positioning portion 40B and the 2 nd positioning portion 50B.
After the reflow process, the solder is cured, the joint 74 is fixed in the joint hole 87, and the substrate connection portion 22 and the ground portion 28 are fixed in the holes 88.
As described above, the connector 10 of embodiment 1 has the 1 st positioning portion 40B long in the left-right direction and the 2 nd positioning portion 50B long in the front-rear direction. Therefore, the reliability of positioning in the front-rear direction can be improved by the 1 st positioning portion 40B, and the reliability of positioning in the left-right direction can be improved by the 2 nd positioning portion 50B. Therefore, according to the connector 10, the reliability of positioning with respect to the circuit board 80 can be improved.
Even if the circuit board 80 is deformed by bending by heating or the like at the time of reflow soldering, the joint 74 can be displaced in the joint hole 87 according to the deformation of the circuit board 80. Therefore, a large stress is not applied to the joint 74.
The 1 st short side isolation portion 44, the 1 st long side isolation portion 45, the 2 nd short side isolation portion 54, the 2 nd long side isolation portion 55, the 3 rd isolation portion 57, and the 4 th isolation portion 58 of the connector 10 are carried on the circuit board. Therefore, a gap is formed between the opposing surface 33 of the case 11 and the circuit board 80. Even if the circuit board 80 is deformed by bending by heating or the like during reflow, the circuit board 80 is not in contact with the opposing surface 33 of the case 11, and is not subjected to a reaction force from the opposing surface 33 side. As a result, the force for deforming the circuit board 80 can be suppressed from being transmitted from the facing surface 33 of the housing 11 to the 1 st positioning portion 40B and the 2 nd positioning portion 50B, and no unnecessary stress can be generated in the 1 st positioning portion 40B and the 2 nd positioning portion 50B.
