Description

  The present invention relates to a connector connection structure for connecting an insulated wire to a circuit board. More specifically, the present invention relates to a connector plug having a pressure contact connected to a core wire of an insulated wire and connected to a connector socket mounted on the circuit board. The present invention also relates to a connector connection structure for connecting a core wire of an insulated wire and a circuit board pattern.

  Conventionally, connecting the core wire of an insulated wire requires time and effort to peel off the insulation coating covering the periphery of the core wire so that the core wire is exposed. An electrical connector using a pressure contact for connection is widely used. To connect the end of a covered wire and a circuit board such as a printed wiring board, connect the end of the covered wire to a connector plug that supports a pressure contact on an insulating housing, and connect the connector plug to a connector socket mounted on the circuit board. The core wire of the insulated wire is electrically connected to the circuit board pattern.

  Hereinafter, a connector connection structure 100 described in Patent Document 1 using a pressure contact for connection with an insulated wire will be described with reference to FIGS. 8 to 10. FIG. 8 is a perspective view of the connector plug 101 to which the ends of the insulated wires 130 are connected. As shown in the figure, the ends of the two insulated wires 130 are respectively placed on the plug housing 102 made of a substantially rectangular parallelepiped synthetic resin. A set of longitudinal grooves 104 into which a contact contact portion 112a of a connection contact 112 (to be described later) is inserted is formed on the rear end side (diagonally left lower side in the figure). It is recessed.

  As shown in FIG. 9, the press contact 105 accommodated in the wire housing chamber 103 is formed in a bowl shape so as to receive the terminal of the insulated wire 130 from above, and from the front, the crimp barrel 106, the locking piece 108, the press contact is formed. The plate portion 107 and the bifurcated contact portion 109 are integrally formed by bending a conductive metal plate. In a state where the press contact 105 is accommodated in the electric wire accommodation chamber 103, the forked contact portion 109 protrudes from the inner wall surface facing the longitudinal groove 104. The pressure contact plate 107 is orthogonal to the insulated wire 130 accommodated in the wire accommodation chamber 103, and a pressure contact groove 107 a that opens in the direction of the circuit board 120 (upward in FIG. 9) is provided in the center. The width of the pressure contact groove 107a between the pair of sandwiching pieces 107b is slightly shorter than the outer diameter of the core wire 130b (not shown) of the insulated wire 130. With this, when the end of the insulated wire 130 is press-fitted from above the pressure contact groove 107a, the pressure contact groove The blade surface inside 107a pierces part of the insulation coating 130a and the core wire 130b, and the press contact 105 and the core wire 130b are electrically connected. Thereafter, the crimp barrel 106 is crimped along the insulation coating 130 a of the insulated wire 130, and the locking piece 108 is locked around the wire housing chamber 103, whereby the end of the insulated wire 130 is plugged via the pressure contact 105. The housing 102 is prevented from coming off from the wire housing chamber 103.

  As shown in FIG. 10, the connector socket 110 mounted on the circuit board 120 includes a socket housing 111 in which a fitting recess for fitting and connecting the connector plug 101 is formed, and an upright support on the socket housing 111. The connection contact 112 is composed of a pair of conductive metal plates. The lower end of the connection contact 112 is solder-connected to a pattern (not shown) of the circuit board 120, and the contact contact portion 112a that stands up in the fitting recess 112 above the connection contact 112 is when the connector plug 101 is inserted into the fitting recess 112. In addition, it is inserted into the longitudinal groove 104 on the connector plug 101 side and comes into contact with the bifurcated contact portion 109 protruding on both sides thereof. As a result, the core wire 130 b of the insulated wire 130 is electrically connected to the pattern of the circuit board 120 via the pressure contact 105 and the connection contact 112.

  As shown in FIG. 11, the conventional connector connection structure 100 described in Patent Document 1 press-fits the end of the insulated wire 130 from above perpendicular to the circuit board 120 into a pressure contact groove 107 a that opens above the pressure contact plate portion 107. The inner blade surface of the pressure contact groove 107 a is pressed against the core wire 130 b of the insulated wire 130. Thus, when press-fitting the press contact plate portion 107 to the insulated wire 130 in the vertical direction, the horizontal width A parallel to the circuit board 120 of the press contact plate portion 107 is set to a length substantially equal to the outer diameter of the insulated wire 130. In contrast, the vertical width B perpendicular to the circuit board 120 is such that a pair of sandwiching pieces 107b is attached to the sandwiching pieces 107b having a length substantially equal to the outer diameter of the insulated wire 130 on both sides of the press contact groove 107a. The length of the connecting piece 107c to be connected is a length obtained by adding the plate width Bα, and the vertical width B is longer than the horizontal width A.

  Thus, the press contact 105 for press-fitting the press contact plate portion 107 in the vertical direction orthogonal to the circuit board 120 becomes higher in the same direction. As a result, the connector plug 101 and the connector plug 101 that accommodate the press contact 105 are provided.

In the device, the connector socket 110 mounted on the circuit board 120 is also required to be as low as possible, but for the reasons described above, the height is limited to 0.9 mm to 1.2 mm. The height could not be reduced below.

Further, in the conventional connector connection structure 100, the bifurcated contact portion 109 of the press contact 105 protrudes further from the end of the insulated wire 130 in the insertion direction of the connector plug 101, and the connector socket 110 disposed further rearward thereof. Since the structure is brought into contact with the contact contact portion 112a, as shown in FIG. 10, the total length along the insertion direction of the connector plug 110 and the connector socket 110 to which the connector plug 101 is connected becomes long, and the mounting area on the circuit board 120 Has become a limitation of high-density mounting.

Since the contact 2 and the core wire 130b are electrically connected and the press contact 2 is press-contacted at two places before and after the insulated wire 130, the insulated wire 130 is firmly fixed to the plug housing 11. Further, as shown in FIG. 3, the contact plate portion 3 of the press contact 2 is exposed on the side surface of the plug housing 11 along the front-rear direction.

  In this embodiment, the pressure contact plate portion 4 of the pressure contact 2 is pushed in from the side surface of the plug housing 11 in the horizontal direction, and the pressure contact groove 4a of the pressure contact plate portion 4 is pressed from the side of the core wire 130b of the insulated wire 130. 11, the width of A is the vertical width and the width of B is the horizontal width, and the height of the plug housing 11 in the vertical direction can be lowered to a length slightly longer than the outer diameter of the insulated wire 130.

  The connector socket 20 includes a socket housing 21 having the fitting recess 21a into which the connector plug 10 to which two insulated wires 130 are connected from the front is inserted, and a fitting recess from the inner side facing the right and left of the fitting recess 21a. When the connector plug 10 is inserted into the fitting recess 21a with the positioning projections 15 facing upward as shown in FIG. The contact plate portions 3 of the press contact 2 exposed on both side surfaces of the housing 11 are in elastic contact with the contact contact portions 23a.

  As shown in FIG. 4, the socket housing 21 is formed by integrally forming a connecting frame portion 25 and a pair of arm portions 26 and 26 protruding forward from both sides of the connecting frame portion 25 with an insulating synthetic resin. The U-shaped frame body 22 formed in a U-shape and a metal cover 24 covering the plane of the U-shaped frame body 22, the surface of the circuit board 120 on which the connector socket 20 is mounted, and the U-shaped frame body 22. The metal cover 24 forms a fitting recess 21a that opens forward.

  In the pair of arm portions 26, 26, a contact receiving groove 26 a that supports the connection contact 23 is formed along the inner surface of the arm portion 26 from the rear surface of the connecting frame portion 25.

  Further, in front of the left and right sides of the rectangular plate shape of the metal cover 24, leg pieces 24c whose lower ends are soldered to the ground pattern of the circuit board 120 along the outer surface of the arm portion 26 of the U-shaped frame body 22 are provided. It is installed vertically. Since the pair of leg pieces 24c are respectively fixed to the circuit board 120 outside the left and right arm portions 26, even if the connector plug 10 is inserted obliquely with respect to the fitting recess 21a, The arm plug 26 guides the connector plug 10 to the fitting recess 21a along the front-rear direction without bending outward. Therefore, there is no need to provide positioning means for positioning with respect to the circuit board 120 mounted on the U-shaped frame body 22 side, and the U-shaped frame body 22 formed of insulating synthetic resin can be formed in a simple and small shape.

  Thus, the lower part of the fitting recess 21a is covered with the surface of the circuit board 120 on which the connector socket 20 is mounted, and the upper part is covered with a metal plate that is thin and has a predetermined strength. The mounting height can be lowered to, for example, 0.6 mm, which is slightly longer than the height of the connector plug 10, that is, the outer diameter of the insulated wire 130. Further, since the metal cover 24 covering the flat side of the fitting recess 21a is connected to the ground pattern and grounded, the pressure contact 2 of the connector plug 10 and the connection contact 23 of the connector socket 20 exposed in the fitting recess 21a are grounded. The upper part is shielded.

  The connection contact 23 is formed by pressing a conductive metal plate material so that the elongated plate-like fixed piece 23b and the front end side of the fixed piece 23b are U-shaped inside (the connection contact 23 is supported by the contact receiving groove 26a). The contact contact portion 23a folded back to the inner side of the fitting recess 21a), and a solder connection portion 23c horizontally provided continuously from the lower surface of the rear end portion of the fixed piece 23b to the outer side opposite to the contact contact portion 23.

In this state, the contact contact portion 23a protrudes into the fitting recess 21a at the front, and the solder connection portion 23c protrudes outward along the bottom surface of the U-shaped frame body 22 at the rear. A signal pattern is formed on the surface of the circuit board 120 facing the pair of solder connection portions 23c, and the stopper piece 24b and the pair of leg pieces 24c of the metal cover 24 are soldered to the ground pattern, and the solder connection portion 23c. Is soldered to the signal pattern, and the connector socket 20 is mounted on the circuit board 120.

  As shown in FIG. 3, the connector plug 10 to which the two insulated wires 130 are connected is inserted from the front into the fitting recess 21a of the connector socket 20 mounted on the circuit board 120 as described above. The connector plug 10 and the connector socket 20 are connected by inserting the positioning protrusion 15 of the connector plug 10 into the positioning recess 24a of the metal cover 24 to the position shown in FIG. 1, and in this connected state, as shown in FIG. Further, the contact contact portions 23a of the connection contacts 23 projecting from both side surfaces of the fitting recess 21a are in elastic contact with the contact plate portions 3 of the press contact 2 exposed on both side surfaces of the plug housing 11, respectively. 130 core wires 130 b are electrically connected to corresponding signal patterns on the circuit board 120.

  Since the pressure contact 2 of the connector plug 10 and the connection contact 23 of the connector socket 20 are the sides in the fitting recess 21a orthogonal to the front-rear direction, which is the insertion direction of the connector plug 10, they are located behind the fitting recess 21a. It is not necessary to arrange the connection contact 23 and the pressure contact 2 and the length of the connector plug 10 and the connector socket 20 in the front-rear direction can be shortened.

  However, if the purpose is only to reduce the height of the connector plug 10 or the connector socket 20 in the vertical direction perpendicular to the circuit board 120, the press contact 2 of the connector plug 10 and the connection contact 23 of the connector socket 20 are fitted together. It is good also as a structure connected behind the recessed part 21a.

  Moreover, in the above-described embodiment, the direction in which the terminal portion of the insulated wire 130 is inserted into the wire housing chamber 12 and the direction in which the connector plug 10 is inserted into the fitting recess 21a are matched, but are orthogonal to the circuit board 120. The connector plug 10 has a structure in which the press contact 2 is pressed against the core wire 130b of the insulated wire 130 from the side surface of the plug housing 11 inserted along the left and right inner surfaces of the fitting recess 21a. May be inserted from the vertical direction of the fitting recess 21a.

  In addition, the pressure contact plate portion 4 having a pair of pressure contact grooves 4a formed in the front and rear is formed on one pressure contact 2 and is press-connected at two different points in the longitudinal direction of the insulated wire 130.
