Description of the Related Art A receptacle connector mounted on a printed circuit board generally includes a housing having a plurality of mounting holes, and contacts fitted and mounted in the mounting holes of the housing. Then, the legs of the contacts protruding from the housing are fitted into through holes provided on the printed circuit board and soldered to be mounted on the printed circuit board.

触不良の原因をもたらす、という問題である。[0003] Such a receptacle connector has a problem that contact is hindered by a flux used for soldering. That is, when soldering the leg of the contact, the flux used for soldering rises along the contact in a capillary phenomenon, and as a result, the contact portion of the contact for electrical contact with the contact of the mating connector is formed. There is a problem that the flux is contaminated, or the flux penetrates between the mounting hole and the contact and changes the spring characteristic of the contact, thereby causing an electrical contact failure.

トまで侵入するのを防止する方法である。The simplest and most effective method for preventing the contact from being hindered by the flux is to form a mounting hole tightly with respect to the contact portion of the contact and to form the contact portion when the contact is fitted and mounted. This method makes the peripheral surface of the mounting hole tightly adhere to the inner surface of the mounting hole to prevent the flux from entering the contact.

きない。[0005] However, this method has a problem that it cannot be used when the contact portion has a contact structure such as a tuning fork shape. In other words, if the contact portion has a contact structure such as a tuning fork shape, it is not possible to provide an excessively large fitting resistance to the contact portion when fitting the contact into the mounting hole of the housing. For this reason, it is necessary to form the fitting loosely with respect to the contact, and it is not possible to secure sufficient adhesion to reliably prevent flux from entering.

ある。Therefore, for a contact having a contact portion that cannot be brought into close contact with the mounting hole, a certain gap is allowed between the mounting hole and the contact. A method of applying an inhibitor to the contact to prevent the contact from occurring, and a method of filling a gap between the contact and the mounting hole with an appropriate filler have been adopted. However, all of these methods increase the cost because the manufacturing process becomes complicated due to the addition of a process of applying an inhibitor or filling a filler, and the material cost increases. There is a problem.

Even when the contact has a contact structure such as a tuning fork, the contact is simply fitted into the mounting hole. It is an object of the present invention to provide a receptacle connector that can reliably prevent flux or the like from intruding simply by being attached.

And each of the contacts has a contact portion enabling electrical contact with a contact of a mating connector, and a leg portion extending from the contact portion. Is basically mounted on the circuit board via the legs. In addition to such a basic structure, the contact has a convex portion on one side surface of the leg portion, and when the contact is fitted into the mounting hole of the housing, the convex portion of the contact is attached to the mounting hole. And one end of the mounting hole is shielded from the invasion of flux or the like to the other end by the contact position of the projection.

なう必要がない。In such a receptacle connector according to the present invention, with respect to one side surface of the contact, the projection provided on the leg portion of the contact is in close contact with the inner surface of one side of the mounting hole in a press-contact manner. By acting as a “seki”, the other side surface of the contact receives the reaction force of pressing the convex portion against the inner surface of the mounting hole, and the other side surface becomes the other side surface of the mounting hole. By pressing against, it is possible to prevent flux and the like from entering. Therefore, it is possible to allow a gap between the contact portion and the mounting hole. For this reason, the contact portion can be fitted into the mounting hole without a large fitting resistance, and the above-described inhibitor is applied or the filler is filled to prevent intrusion of flux or the like. No need.

侵入を防止できる。[0010] In the receptacle connector as described above, it is more preferable that a concave portion is formed in the leg portion of the contact on the surface opposite to the convex portion forming surface so as to correspond to the convex portion. The concave portion provided in correspondence with the convex portion functions to more reliably prevent intrusion of flux or the like. That is, when the concave portion forming surface of the leg portion is pressed against the inner surface of the mounting hole under the reaction force of the pressing of the convex portion to the inner surface of the mounting hole, the housing is generally formed of a plastic having appropriate plasticity. Therefore, the inner surface of the mounting hole bulges so as to cut into the concave portion, thereby forming a liquid-tight structure between the concave portion and the inner surface of the mounting hole. It is possible to more reliably prevent the intrusion of flux or the like than in the case of just touching.

As a specific structure, as shown in an enlarged view in FIG. 6, a tuning fork-shaped contact portion 4 is provided at the distal end, and a leg 5 is provided at the proximal end. The leg 5 is provided with a tightened portion 6 having the same width as the maximum width portion of the contact portion 4 (the base end of the contact portion 4 corresponds to the portion in the illustrated example).
Protrusions 7 and depressions 8 having an appropriate area are provided. This convex part 7
The recess 8 is formed by press-molding from the side of the recess 8 to simultaneously form the recess of the recess 8 and the protrusion of the projection 7. The tightened portion 6 has a convex portion 7 and a concave portion 8.
Auxiliary recesses 9 and 9 are provided in notches on the respective surfaces intersecting with the formation surfaces, in correspondence with the formation positions.

The mounting hole 2 has a width slightly larger than the thickness of the contact 3, and has a slit shape having a length substantially equal to the width of the contact 3. The contact hole 11 is formed in a direction perpendicular to the elongated receiving hole 11 for receiving the contact. Therefore, the distal end side of the mounting hole 2 is in the position shown in FIG.
As shown in FIG. 5, a state is obtained in which a groove is formed in the inner wall of the receiving hole 11.

へ侵入するのを確実に防止できる。The relationship between the mounting hole 2 and the contact 3 fitted and mounted in the mounting hole 2 is shown in FIG. 4 and FIG. Since the width of the mounting hole 2 is larger than the thickness of the contact portion 4, the contact portion 4 has a slight gap with respect to the mounting hole 2.
Therefore, no fitting resistance needs to be given to the contact portion 4. On the other hand, with respect to the tightened portion 6, the convex portion 7 thereof comes into close contact with the inner surface on one side of the mounting hole 2 and at the same time receives the reaction force, the surface on the opposite side of the contact 3, that is, the concave portion. The surface on which the side 8 is formed comes into close contact with the inner surface on the other side of the mounting hole 2. And, due to such close contact, the protrusion 7
The inner wall of the mounting hole 2 is slightly protruded by the convex portion 7 at the portion corresponding to, and the inner wall of the mounting hole 2 slightly protrudes into the concave portion 8 at the portion corresponding to the concave portion 8. Such swelling also occurs in the auxiliary recesses 9 and 9. As a result, the contact 3 is brought into close contact with the mounting hole 2 in a highly liquid-tight state by the tightened portion 6, so that the flux or the like intrudes into the contact portion 4 without fail. Can be prevented.
