Description

  The present invention relates to a jack connector into which a cable plug or the like is inserted, and more particularly, to a jack connector in which a soldered portion with a substrate is hardly broken even when an external force is applied to the inserted plug, and a portable terminal including the jack connector.

  As shown in FIG. 9, the jack connector has a structure in which a metal shell 11 covers a housing mold 13 around which terminals are held and fixed. In addition, as shown in FIG. 10, the housing mold 13 is fixed to the metal shell 11 by bending a part of the metal shell 11 to form the holding portion 12. One end side of the terminal 14 extends in parallel with the plug insertion direction to form a contact portion 14c, and is brought into contact with the terminal of the plug to realize electrical coupling. A tail portion 14 a is formed at the other end of the terminal 14, and this portion is soldered to the wiring pattern on the substrate 20. The housing mold 13 includes a flat plate portion 13a substantially parallel to the substrate 20, and the contact portion 14c of the terminal 14 is fixed to the flat plate portion 13a. Further, the metal shell 11 is fixed to the substrate 20 via a soldering piece 15 formed parallel to the substrate 20, a through-hole peg 16 formed vertically, and the like.

  Although the plug is inserted from the opening of the metal shell 11, in order to realize a reliable fitting, the insertion portion is set longer in the dimension of the insertion portion of the plug and the depth dimension inside the jack connector. It is common.

  For this reason, when the plug is inserted vigorously or when the plug receives a strong external force after being inserted (such as an impact due to dropping), the plug end surface hits the bottom surface of the housing 13 of the jack connector, and the housing from the metal shell 11 An attempt is made to push out the mold 13. The housing mold is fixed by a holding part 12 formed by bending a part of the metal shell 11, but if a strong force is applied, the holding part 12 itself is deformed and the housing mold 13 may come out of the metal shell 11. is there. As a result, stress is applied to the terminal 14 and the tail portion 14a, and solder peeling occurs.

  Although a method of increasing the strength of the holding unit 12 by increasing the number of holding units 12 or increasing the thickness or width of the holding unit 12 so that the housing mold 13 does not come out can be considered, it is necessary to reduce the size and weight. There is a limit in the connector to be used, and it is difficult to give the holding portion 12 sufficient strength.

As a technique related to increasing the strength of a connector, there is a “connector-integrated electronic device” disclosed in Patent Document 1. In the invention disclosed in Patent Document 1, when one end of a connector pin is not restrained by a case, when stress is generated due to contraction accompanying a temperature change, the stress applied to the connector pin is relieved.

  However, the invention disclosed in Patent Document 1 is a structure in which connector pins are arranged perpendicular to the substrate, and the connector pins are assumed to be straight rods. That is, the invention disclosed in Patent Document 1 cannot be applied to a jack connector having a structure in which a terminal is bent and arranged in parallel with a substrate as shown in FIG.

  The present invention has been made in view of the above problems, and is a jack connector in which a plug can be inserted / removed in parallel with an installed board, and a soldered portion with the board is not easily broken even if an external force acts on the inserted plug. And it aims at providing a portable terminal provided with this.

  In order to achieve the above object, the present invention provides, as a first aspect, a jack connector that is installed so that the plug insertion / extraction direction is parallel to the substrate, and a cylindrical shell having both ends opened, A housing mold having a flat plate portion fixed to one end portion of the shell and disposed substantially parallel to the substrate at a predetermined distance from the substrate, wherein the end surface of the plug inserted from the other end side of the shell hits the bottom surface; A terminal contact having a shape in which a contact portion on one end fixed to the flat plate portion of the mold and a fixing portion on the other end fixed to the substrate are bent at substantially right angles to the intermediate portion, respectively. The part penetrates the bottom surface of the housing mold and reaches one end of the shell, and is bent at the one end to be connected to the intermediate part. The intermediate part of the terminal is the housing molding only near the boundary with the contact part. Coming into contact with and provides a jack connector according to claim.

  Moreover, in order to achieve the said objective, this invention provides the portable terminal provided with the jack connector which concerns on the said 1st aspect of this invention as a 2nd aspect.

  According to the present invention, there is provided a jack connector capable of inserting and removing a plug in parallel with a board to be installed, and being hard to break a soldered portion with the board even if an external force is applied to the inserted plug, and a portable terminal equipped with the jack connector. Can be provided.

[First Embodiment]
A first embodiment in which the present invention is suitably implemented will be described.
In FIG. 1, the external appearance of the jack connector 100 which concerns on this embodiment is shown. FIG. 2 shows a cross section of the jack connector 100 according to the present embodiment.
The metal shell 1 has a cylindrical shape with both ends opened. A housing mold 3 molded of synthetic resin is inserted into one of the openings, and the metal shell 1 and the housing mold 3 are fixed by caulking by a holding portion 2 obtained by bending a part of the metal shell 1. The metal shell 1 is fixed to the substrate 20 by a known method (for example, a method using a soldering piece or a through-hole peg as shown in FIG. 9). The illustration of the structure is omitted.

  The terminal 4 is made of metal and is fixed by being press-fitted and held in a hole provided so as to penetrate the bottom surface of the housing mold 3 or integrally formed with the housing mold 3.

  One end side of the terminal 4 extends in parallel with the plug insertion direction to form a contact portion 4c, and is brought into contact with the terminal of the plug to realize electrical coupling. The other end side is bent toward the substrate 20 when protruding from the housing mold 3 to form an intermediate portion 4b. In the vicinity of the bent portion, the terminal 4 is in contact with the housing mold 3 to suppress the deflection of the terminal 4.

  The housing mold 3 includes a flat plate portion 3a substantially parallel to the substrate 20, and the contact portion 4c of the terminal 4 is fixed to the flat plate portion 3a. In addition, the housing mold 3 is provided with a recess so that the terminal 4 does not come into contact with a portion closer to the substrate 20 than the bent portion, thereby forming a gap 5. The terminal 4 reaching the surface of the substrate 20 is bent in parallel with the substrate surface to increase the soldering area to form a tail portion 4a, and the tail portion 4a is soldered to a wiring pattern on the substrate 20. The That is, the terminal 4 has a shape in which the contact portion 4c on one end side and the tail portion 4a on the other end side of the intermediate portion 4b are bent substantially at right angles to the intermediate portion 4b.

  As shown in FIG. 3, the jack connector 100 is mounted on the portable terminal 200 for inserting a charging plug.

  When the plug is inserted into the jack connector 100, the end surface of the plug 30 and the bottom surface of the housing mold 3 come into contact as shown in FIG. When a strong external force is applied to the plug 30 by dropping or the like in a state where the end surface of the plug 30 and the bottom surface of the housing mold 3 are in contact with each other, the force is transmitted to the bottom surface of the housing mold 3. As a result, the housing mold 3 tries to move in a direction in which an external force is applied, but its movement is restricted by the holding portion 2 formed on the metal shell 1. However, when a force exceeding the load bearing strength of the holding portion 2 is applied, the holding portion 2 is deformed without being able to endure, and the housing mold 3 moves as the holding portion 2 is deformed, and the terminal 4 is also deformed accordingly. .

In the jack connector having the structure shown in FIG. 10, since the entire portion (intermediate portion) 14b of the terminal 14 perpendicular to the substrate 20 is in contact with the housing mold 13, when the housing mold 13 moves, the terminal 14 Will follow the movement. That is, the stress generated by the force for moving the terminal 14 is directly transmitted to the tail portion 14a.
On the other hand, in this embodiment, the intermediate portion 4b of the terminal 4 is in contact with the housing mold 3 only in a part (only in the vicinity of the bent part), and the other part is not in contact. Further, since the terminal 4 is made of a metal material, it has a certain degree of springiness. For this reason, even if the housing mold 3 starts to move, the terminal 4 is only partly deformed to change the bending angle, and does not move. For this reason, the stress generated by the force for moving the terminal 4 is hardly transmitted to the tail portion 4a.

  That is, as shown in FIG. 2, since there is a gap 5 between the terminal 4 and the housing mold 3, when the housing mold 3 moves out of the metal shell 1, it is bent into a crank shape. The terminal 4 is deformed into a Z shape. Therefore, the stress applied to the soldering surface of the tail portion 4a is reduced.

  Thus, the jack connector according to the present embodiment is less likely to break the soldered portion with the board even when an external force is applied to the inserted plug.

[Second Embodiment]
A second embodiment in which the present invention is suitably implemented will be described.
FIG. 5 shows a configuration of a jack connector 100 according to the second embodiment in which the present invention is preferably implemented. The structure is substantially the same as that of the first embodiment, except that the tail portion 4a is bent in the opposite direction. That is, in the first embodiment, the tail portion 4a is bent in the plug insertion direction, but in the present embodiment, the tail portion 4a is bent in the plug extraction direction. For this reason, when the housing mold 3 comes out of the metal shell 1 and the terminal 4 starts to deform, the structure of the first embodiment is deformed so that the angle formed by the intermediate portion 4b and the tail portion 4a is smaller than 90 degrees. On the other hand, in this embodiment, it deform | transforms so that the angle which the intermediate part 4b and the tail part 4a make may become large.

  The deformation resistance when the intermediate portion 4b and the tail portion 4a are deformed to be small is larger than the deformation resistance when the angle between the intermediate portion 4b and the tail portion 4a is largely deformed. Therefore, as shown in FIG. 6A, even in the case of the configuration of the first embodiment, even when an external force of a magnitude that causes the tail portion 4a to peel from the substrate 20 without the terminal 4 being deformed acts. As shown in (b), the terminal 4 can be reliably deformed in the configuration of the present embodiment. Thereby, it can prevent that the tail part 4a peels from the board | substrate 20. FIG.

  Further, since the tail portion 4a does not protrude from the metal shell 1, the area required for mounting the jack connector 100 can be reduced as compared with the first embodiment.

  Similar to the jack connector according to the first embodiment, the jack connector according to the present embodiment is less likely to break the soldered portion with the board even if an external force acts on the inserted plug.

Each of the above embodiments is an example of a preferred embodiment of the present invention, and the present invention is not limited to these.
For example, in the above-described embodiment, the configuration in which the holding portion 2 is formed by bending the end portion of the metal shell 1 has been described as an example. However, as shown in FIG. The holding part 2 may be formed by being bent. Further, instead of forming the holding portion by bending the metal shell 1, the housing mold 3 may be fixed to the metal shell by penetrating the metal shell 1 and embedding the pins 8 or the like as shown in FIG. good.
As described above, the present invention can be variously modified.
