Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connector, and more particularly to a connector in which linear contacts and insulating linear bodies are alternately arranged.
[0002]
[Prior art]
Conventionally, as a connector in which linear contacts and insulating linear bodies are alternately arranged, a connector made of a woven body is known (see Patent Document 1 below).
[0003]
The woven fabric is formed by alternately weaving conductive yarns and second insulating yarns, which are weft yarns, into first insulating yarns, which are warp yarns.
[0004]
The first insulating yarn is made of a material such as a synthetic resin having elasticity. The conductive yarn is formed from a metal conductive material such as copper or stainless steel. The conductive yarn has a smaller diameter than the first insulating yarn. The second insulating yarn is formed from a material such as synthetic resin. The second insulating yarn has the same diameter as the conductive yarn or a slightly smaller diameter. The conductive yarn and the second insulating yarn are bonded to each other with an adhesive.
[0005]
The connector made of this woven body is disposed between the first printed circuit board and the second printed circuit board, and electrically connects both printed circuit boards. At this time, a connector made of a woven material is sandwiched between the two printed boards by locking means such as bolts.

[0019]
As shown in FIG. 1, the receptacle connector 10 includes an insulator 11, a linear contact 13, an insulating linear body 15, and a hold down 17.
[0020]
The insulator 11 is formed of an insulating material and has a casing shape with an upper surface opened, and has a bottom portion 111 and side wall portions 112, 112, 113, 113.
[0021]
Grooves 111a parallel to each other are formed on the bottom 111 (see FIG. 4). An accommodation recess 111b is formed in the bottom 111 so as to be adjacent to the groove 111a.
[0022]
The side wall portion 112 is adjacent to the groove 111a. A winding part 112 a is formed in the middle part of the side wall part 112. The winding part 112a is thinner than the both ends of the side wall part 112, and the cross-sectional shape is substantially U-shaped. A plurality of V-shaped positioning grooves (positioning portions) 112b are formed in the winding portion 112a from the inner surface to the outer surface of the winding portion 112a (see FIG. 6). Except for the portion formed in the upper part of the winding part 112a, the positioning groove 112b is substantially parallel to the fitting / removing direction a of the plug connector 30 with respect to the receptacle connector 10.
[0023]
Inclined surfaces 112 c and 113 c are formed on the upper surface of both end portions of the side wall portion 112 and the upper surface of the side wall portion 113 so that the plug connector 30 can be easily guided into the insulator 11.
[0024]
The linear contact 13 is a single-core thin wire and has conductivity.
[0025]
The insulating linear body 15 is made of an elastomer and has elasticity.
[0026]
The hold down 17 has a frame shape and is mounted on the outer peripheral surface of the insulator 11. The hold-down 17 presses the linear contact 13 and the insulating linear body 15 against the winding portion 112a, and prevents the linear contact 13 and the insulating linear body 15 from separating from the winding portion 112a. The hold down 17 has a hold down unit 17a. The hold-down part 17a is soldered to the pad 52 of the printed circuit board 50.
[0027]
Since the holddown 17 is made of metal, a strip-like insulating film is formed between the linear contact 13 and the insulating linear body 15 and the holddown 17 in order to insulate the linear contact 13 from the holddown 17. 19 is arranged.
[0028]
In assembling the receptacle connector 10, first, the linear contacts 13 and the insulating linear bodies 15 are arranged alternately adjacent to each other (see FIG. 3). In this state, one end of the linear contact 13 and the insulating linear body 15 is inserted into the groove 111a and fixed.
[0029]
Next, the linear contact 13 and the insulating linear body 15 are wound around the winding portion 112b with the inside of the positioning groove 112b. Thereafter, the hold down 17 is attached to the insulator 11 around which the linear contact 13 and the insulating linear body 15 are wound. At this time, the insulating film 19 is interposed between the linear contact 13 and the insulating linear body 15 and the hold down 17. If the hold down 17 is attached to the insulator 11 in this way, the linear contact 13 and the insulating linear body 15 are reliably held by the insulator 11 and the hold down 17.
[0030]
Finally, the other end of the linear contact 13 is bent so as to face the conductor pattern 51 of the printed circuit board 50.
[0031]
The receptacle connector 10 assembled as described above is mounted on the printed circuit board 50 by reflow soldering. At the time of this reflow soldering, the linear contact 13 is soldered to the conductor pattern 51, and the holddown portion 17 a of the holddown 17 is soldered to the pad 52 of the printed circuit board 50. The receptacle connector 10 is securely fixed to the printed circuit board 50 by soldering the hold-down portion 17a to the pad 52.
[0032]
Next, the plug connector 30 that is the mating connector of the receptacle connector 10 will be described.
[0033]
As shown in FIG. 1, the plug connector 30 includes an insulator 31, a linear contact 33, and an insulating linear body 35.
[0034]
The insulator 31 is formed of an insulating material and has a casing shape with an upper surface opened, and has a bottom portion 311 and side wall portions 312, 312, 313, and 313.
[0035]
The bottom 311 abuts against the bottom 111 of the receptacle connector 10 when the plug connector 30 is fitted to the receptacle connector 10 (see FIG. 2). Grooves 311a parallel to each other are formed in the bottom 311 (see FIG. 4).
[0036]
The side wall portion 312 is adjacent to the groove 311a. The cross-sectional shape of the side wall 312 is U-shaped. When the plug connector 30 is fitted to the receptacle connector 10, the side wall 312 faces the side wall 112 (see FIG. 2). A plurality of V-shaped positioning grooves (positioning portions) 312b are formed in the side wall portion 312 from the inner surface to the outer surface of the side wall portion 312 (see FIG. 6). Except for the portion formed in the upper portion of the side wall portion 312, the positioning groove 312 b is parallel to the fitting / removing direction a of the plug connector 30 with respect to the receptacle connector 10. The arrangement pitch of the positioning grooves 312b is equal to the arrangement pitch of the positioning grooves 112b. However, when the plug connector 30 is fitted to the receptacle connector 10, the positioning groove 312b is displaced in the arrangement pitch direction by a length that is half the arrangement pitch with respect to the positioning groove 112b (see FIG. 6).
[0037]
When the plug connector 30 is fitted to the receptacle connector 10, the side wall portion 313 faces the side wall portion 113 (see FIG. 5).
[0038]
The linear contact 33 is a single-core thin wire and has conductivity.
[0039]
The insulating linear body 35 is made of an elastomer and has elasticity.
[0040]
In assembling the plug connector 30, first, the linear contacts 33 and the insulating linear bodies 35 are arranged alternately adjacent to each other (see FIG. 3). In this state, one end of the linear contact 33 and the insulating linear body 35 is inserted into the groove 311a and fixed. Next, the linear contact 33 and the insulating linear body 35 are wound around the side wall portion 312 with the inside of the positioning groove 312b. Finally, the other end of the linear contact 33 is bent so as to face the conductor pattern (not shown) of the printed circuit board 70.
[0041]
The plug connector 30 assembled as described above is mounted on the printed circuit board 70 by reflow soldering. At the time of this reflow soldering, the linear contact 33 is soldered to the conductor pattern of the printed circuit board 70.
[0042]
In order to electrically connect the printed circuit board 50 and the printed circuit board 70, it is only necessary to fit the plug connector 30 into the receptacle connector 10 as shown in FIG. 2 from the state shown in FIG. There is no need to lock the substrates 50 and 70 with locking means.
[0043]
When the linear contact 33 and the insulating linear body 35 wound around the side wall portion 312 of the plug connector 30 are inserted into the receiving recess 111b of the receptacle connector 10, the linear contacts 13 and 33 are as shown in FIG. Are respectively sandwiched between the insulating linear bodies 15 and 35, pressed by the elastic forces Fr1, Fr2, Fp1, and Fp2 of the insulating linear bodies 15 and 35, and the reaction forces Rr and Rp of the elastic forces Fr2 and Fp2. Occurs. As shown in FIG. 8, a force represented by a vector V is generated in the linear contact 13, and in the x direction (a virtual straight line connecting the central axis of the linear contact 13 and the central axis of the linear contact 33 in the shortest direction). The component force Vx in the parallel direction is the contact force of the linear contact 13 with respect to the linear contact 33. The component force Vy in the y direction (the direction perpendicular to the x direction and the central axis) of the force represented by the vector V is a force that presses the linear contact 13 against the side wall portion 112. A force represented by the vector V ′ is also generated in the linear contact 33. It can be divided into component force Vx ′ and component force Vy ′. The force represented by the vector V ′ has the same magnitude as the force represented by the vector V and has the opposite direction. The component force Vx ′ has the same magnitude as the component force Vx and has the opposite direction, and becomes a contact force of the linear contact 33 to the linear contact 13. Similarly, the component force Vy ′ has the same magnitude as the component force Vy and has the opposite direction, and becomes a force for pressing the linear contact 33 against the side wall portion 312.
[0044]
As described above, according to this embodiment, when the insulator 31 of the plug connector 30 is fitted to the insulator 11 of the receptacle connector 10, the linear contacts 13 and 33 are connected to each other by the elastic force of the insulating linear bodies 15 and 35. Since the contact state is maintained, a locking means for obtaining a high contact force is unnecessary, and the printed circuit boards 50 and 70 can be easily connected to each other.
[0045]
As described above, in the receptacle connector 10, the positioning groove 112 b for positioning the linear contact 13 and the insulating linear body 15 is formed in the insulator 11. In the plug connector 30, the linear contact 33 and the insulating linear body 35 are formed. Since the positioning groove 312b is formed in the insulator 31, the positions of the linear contacts 13, 33 and the insulating linear bodies 15, 35 are greatly displaced when the plug connector 30 is fitted to the receptacle connector 10. Absent. Therefore, when the plug connector 30 is fitted to the receptacle connector 10, the linear contacts 13 and 33 are reliably in contact with each other, so that the reliability is high.
[0046]
As described above, since the receptacle connector 10 includes the hold-down 17 having the hold-down portion 17a, the receptacle connector 10 can be securely fixed to the printed circuit board 50. Further, when the insulator 31 of the plug connector 30 is fitted to the insulator 11 of the receptacle connector 10, the deformation of the insulator 11 is suppressed by the hold down 17, so that the strength of the insulator 11 can be increased.
[0047]
In this embodiment, the positioning grooves 112b and 312b are substantially parallel to the fitting / removing direction a, but it is not always necessary to configure in this manner.
[0048]
Further, although the positioning grooves 112b and 312b are employed as positioning portions for positioning the linear contacts 13 and 33 and the insulating linear bodies 15 and 35, respectively, the positioning portions are not limited to the positioning grooves 112b and 312b.
[0049]
Note that the plug connector 30 in which the linear contacts 33 and the insulating linear members 35 are arranged alternately and adjacent to each other as the mating connector of the receptacle connector 10 is employed, but the mating connector of the receptacle connector 10 is a plug. Not only the connector 30 but also a general plug connector (not shown) in which pin contacts are arranged on an insulator can be adopted.
[0050]
Further, the mating connector of the plug connector 30 is not limited to the receptacle connector 10, and a general receptacle connector (not shown) may be employed.
[0051]

As described above, according to the connector of the first aspect of the present invention, when the insulator is fitted to the insulator of the mating connector, the linear contact contacts the contact of the mating connector by the elastic force of the insulating linear body. Therefore, the locking means for obtaining a high contact force is unnecessary, and two connection objects can be easily connected to each other.
[0052]
According to the connector of the first aspect of the present invention, since the positions of the linear contact and the insulating linear body are not greatly shifted, the linear contact can be reliably brought into contact with the contact of the mating connector.
[0053]
