Conventionally, in the connection of the core wire of the insulated wire, it is necessary to peel off the insulating clad layer around the core wire to expose the core wire. Therefore, the insulating clad is pierced by the crimping groove of the crimping plate portion, and the insulating clad layer is directly clamped. Electrical connectors for crimp contacts that are connected to their center cores are widely used. In the connection of the end of the covered electric wire to the circuit board of the printed circuit board or the like, the end of the covered wire is connected with the connector plug that supports the crimping contact to the insulating case, and then the connector plug is mounted. The connector sockets on the board are connected such that the core of the insulated wire is electrically connected to the pattern of the board.

Hereinafter, the connection structure 100 of the connector disclosed in Patent Document 1 in which the pressure contact is used in connection with the insulated wire will be described with reference to FIGS. 8 to 10. 8 is a perspective view of the connector plug 101 connecting the ends of the insulated wires 130. As shown in the drawing, in a plug housing 102 formed of a substantially rectangular parallelepiped synthetic resin, a set of wire housing chambers 103 are recessed. It is possible to accommodate the ends of the two insulated wires 130 from above, and at the same time on the rear end side thereof (the lower left side in the figure), a set of vertical grooves 104 are recessed to be inserted into the contact contacts of the connecting contacts 112 to be described later.

The 107 and the double-fork contact portion 109 are integrally formed by bending a conductive metal plate from the front. In a state in which the pressure contact head 105 is housed in the wire housing chamber 103, the double-fork contact portion 109 protrudes from the inner wall surface opposed to the vertical groove 104. The crimping plate portion 107 is orthogonal to the insulated wire 130 housed in the wire housing chamber 103, and a crimping groove 107a whose opening faces the circuit board 120 (upward in FIG. 9) is recessed in the center. The width of the crimping groove 107a between the set of holding pieces 107b is slightly shorter than the outer diameter of the unillustrated core wire 130b of the insulated wire 130, whereby the end of the insulated wire 130 is above the crimping groove 107a. At the time of press-fitting, the blade surface on the inner side of the crimping groove 107a pierces the insulating cladding 130a and a part of the core wire 130b, thereby electrically connecting the crimping contact 105 and the core wire 130b. Next, the crimping cylinder 106 is pressed along the insulating sheath 130a of the insulated wire 130, and is locked around the wire receiving chamber 103 by the locking piece 108, so that the end of the insulated wire 130 is passed from the pressing contact 105. The wire housing chamber 103 of the plug housing 102 is locked.

As shown in FIG. 10, the connector socket 110 mounted on the circuit board 120 is formed by a socket housing 111 formed by a fitting recess that can be fitted and connected to the connector plug 101, and erected by the socket housing 111. A set of conductive metal plates is formed by connecting the contacts 112. The lower end of the connection contact 112 is soldered to a diagram (not shown) of the circuit board 120. Further, in addition, the contact contact portion 112a standing upright in the fitting recess 112 above it is inserted into the vertical groove 104 on the side of the connector plug 101 when the connector plug 101 is inserted into the fitting recess 112, and The double-fork contact portion 109 projecting to both sides thereof is in contact. As a result, the core wire 130b of the insulated wire 130 is electrically connected to the pattern of the circuit board 120 via the crimp contact 105 and the connection contact 112.

The surface side of the circuit board 120 of 20 is described above.

The insulated wire 130 is composed of a core wire 130b formed of a single wire or a twisted wire formed of a conductive material, and an insulating cladding 130a which is coaxially coated on the core wire 130b. In the surrounding, the connector plug 10 is provided with a set of pressure contact heads 2, 2 electrically connected to a core wire 130b of each of the insulated wires 130; and a terminal portion of the holding insulated wire 130 and a set of pressure contact heads 2 A plug housing 11 made of insulating resin.

The pressure contact heads 2 and 2 are formed by pressing a conductive metal plate and forming a right angle with the rectangular plate-shaped contact plate portion 3 and the longitudinal ends of the contact plate portion 3 in parallel with each other. One of the pair of crimping plate portions 4 is integrally formed, as shown in FIG. 5, which is viewed from the vertical direction. Glyph. The crimping plate portion 4 is formed by continuously providing a pair of holding pieces 4b, 4b from the both sides of the connecting piece 4c toward the side opposite to the contact piece 3, and forming a crimping groove 4a inside thereof. The inner side surface and the top end surface of the pair of holding pieces 4b and 4b on the side of the pressure-bonding groove 4a are formed into a tapered surface to cut and pierce the blade surface of the insulating coating 130a of the insulated wire 130. In order to press the crimping plate portion 4 of the contact head 2, it can be pressed from the side of the insulated wire 130 and crimped onto the core wire 130b, and the length between the inner side faces of the pair of holding pieces 4b, 4b, that is, the crimping The width of the groove 4a is slightly shorter than the outer diameter of the core wire 130b of the insulated wire 130, and the length between the outer side faces, that is, the width of the crimping plate portion 4 is substantially equal to the outer diameter of the insulated wire 130.

The plug housing 11 is formed in a rectangular parallelepiped shape by an insulating resin, and has cylindrical electric wire housing chambers 12 and 12 which are respectively recessed at the ends of the front surface of the front surface of the two insulated wires 130. . The inner diameter of the wire housing chamber 12 is slightly longer than the outer diameter of the insulated wire 130, and the rear end thereof is closed by the rear wall of the plug housing 11. Therefore, the distal end portion of the insulated wire 130 inserted into the electric wire housing chamber 12 from the front direction is positioned in the electric wire housing chamber 12 in each direction except for the front in the extraction direction.

As shown in FIG. 5, the terminal accommodating portion 13 for accommodating the contact plate portion 3 of the pressure contact head 2 in the front-rear direction is recessed on the right and left side faces of the plug housing 11, and the front end and the rear of the terminal accommodating portion 13 are provided. The end is provided with a crimping guide hole 14 that communicates with the wire housing chamber 12 in a horizontal direction orthogonal to the left and right side surfaces. The pressure contact guide hole 14 is formed in a square hole shape in which the crimping plate portion 4 of the pressure contact head 2 is inserted, and the contact plate portion 3 of the pressure contact heads 2 and 2 is directed from the side surface to the terminal housing portion 13 by using a jig or the like. At the time of press-fitting, the crimping plate portion 4 protrudes into the electric wire housing chamber 12 through the crimping guide hole 14 that is orthogonal to the side surface of the plug housing 11. By In the press-fitting step, the blade surface of the holding piece 4b of the crimping plate portion 4 can cut and pierce the insulating clad 130a of the insulated wire 130 housed in the electric wire housing chamber 12, and the crimping groove 4a of the crimping plate portion 4 The pressure is crimped from the side of the core wire 130b.

Until the contact plate portion 3 of the pressure contact head 2 is completely housed in the terminal housing portion 13, when the crimping plate portion 4 is pressed in from the side surface, it is crimped onto the core wire 130b of the insulated wire 130 by the crimping groove 4a. The crimping contact 2 is electrically connected to the core wire 130b, and at the same time, the crimping contact 2 is crimped to the front and rear 2 of the insulated wire 130, so that 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 pressure contact head 2 is exposed to the side surface of the plug housing 11 in the front-rear direction.

In this manner, the crimping plate portion 4 of the pressure contact head 2 is pressed in the horizontal direction from the side surface of the plug housing 11, and the crimping groove 4a of the crimping plate portion 4 is crimped from the side surface of the core wire 130b of the insulated wire 130. In the present embodiment, the width of A in FIG. 11 is the width in the vertical direction, and the width of B is the width in the horizontal direction, so that the height in the vertical direction of the plug housing 11 can be lowered to a lower level than the outer diameter of the insulated wire 130. Long length.

Further, in the plug housing 11, when the connector plug 10 is inserted into the fitting recess 21a of the connector socket 20, the positioning projection 15 which is fitted to the positioning recess 24a at the front end of the plane of the fitting recess 21a is provided. At the center of the front end portion of the plane, the connector plug 10 is positioned at a substantially central position of the insertion fitting recess 21a.

The connector socket 20 includes a socket housing 21 and a pair of connection contacts 23, and the socket housing 21 has the fitting recess 21a into which the connector plug 10 that connects the two insulated wires 130 is inserted from the front. The pair of connection contacts 23 have contacts that protrude from the inner side surface opposite to the right and left of the fitting recess 21a into the fitting recess 21a As shown in FIG. 3, as shown in FIG. 3, the pressing contact head 2 exposed to both side faces of the plug housing 11 can be formed by setting the positioning projection 15 upward and inserting the connector plug 10 into the fitting recess 21a. The contact plate portions 3 are in elastic contact with the contact contact portions 23a, respectively.

As shown in FIG. 4, the socket housing 21 is formed by integrally molding the connecting frame portion 25 with an insulating synthetic resin and projecting the pair of arm portions 26 and 26 forward from both sides of the connecting frame portion 25. Glyph Word box 22, and coverage The metal cover 24 of the plane of the word frame 22 is formed by the surface of the circuit board 120 on which the connector socket 20 is mounted. The word frame body 22 and the metal cover 24 form a fitting recess 21a that opens toward the front.

The pair of arm portions 26 and 26 are formed by the contact receiving groove 26a of the support connecting contact 23 from the rear surface of the connecting frame portion 25 along the inner side surface of the arm portion 26, and the connecting frame portion 25 is recessed. There is a receiving groove 25a for allowing the stopper piece 24b of the metal cover 24 to be inserted into the vertical direction.

The metal cover 24 is formed to cover The frame 22 has a rectangular plate shape in plan view, and a stopper piece 24b is vertically disposed from the center of the rear end thereof in the vertical direction. The limiting piece 24b is inserted into the grounding pattern of the circuit board 120 at the lower end of the receiving groove 25a, whereby the limiting piece 24b can withstand the strong insertion force from the connector plug 10 even if the socket housing 21 receives strong insertion force from the connector plug 10. The insertion force is not transmitted to the welded portion 23c of the connection contact 23 which will be described later supported by the socket housing 21.

In addition, in front of the left and right sides of the rectangular plate shape of the metal cover 24, along The outer side surface of the arm portion 26 of the word frame 22 is vertically provided with a leg piece 24c whose lower end is soldered to the ground pattern of the circuit board 120. Since the pair of leg pieces 24c are respectively fixed to the circuit board 120 on the outer side of the right and left arm portions 26, the arm portion 26 can be warped without being bent outward even if the connector plug 10 is obliquely inserted or inserted into the fitting recess portion 21a. The connector plug 10 is guided to the fitting recess 21a in the front-rear direction. Thus, for The circuit board 120 mounted on the side of the word frame 22 is formed of an insulating synthetic resin without providing a positioning means for positioning the same. The word frame 22 is formed into a simple and small shape.

Thus, the connector socket can be covered by covering the lower surface of the fitting recess 21a with the surface of the circuit board 120 on which the connector socket 20 is mounted, and covering the upper portion thereof with a metal plate capable of obtaining a predetermined strength with a thin wall. The mounting height on the circuit board of 20 is lowered to a height higher than the height of the connector plug 10, that is, a length slightly longer than the outer diameter of the insulated wire 130, and can be lowered to 0.6 mm. Further, since the metal cover 24 covering the planar side of the fitting recess 21a is grounded in connection with the ground pattern, the contact contact of the crimping contact 2 or the connector socket 20 of the connector plug 10 exposed in the fitting recess 21a is touched. The top of the head 23 can be shielded.

The connecting contact 23 is formed by pressing a conductive metal plate material such that the front end sides of the elongated plate-shaped fixing piece 23b and the fixing piece 23b are U-shaped toward the inner side (the connecting contact 23 is supported by the contact receiving groove 26a). In the state of the fitting recess 21a, the contact contact portion 23a which is folded back, and the welded portion 23c which is horizontally continuously provided from the lower surface of the rear end portion of the fixing piece 23b to the outer side of the opposite side of the contact contact portion 23 are integrated. Forming.

As shown in FIG. 6, the connection contact 23 is inserted from the rear of the contact housing groove 26a and mounted along the inner side surface of the arm portion 26, as shown in FIG. In the state of the word frame 22, the contact contact portion 23a protrudes inward from the fitting recess 21a, and the welded portion 23c is parallel along the rear side. The bottom surface of the word frame 22 protrudes outward. A signal pattern is formed on the surface of the circuit board 120 facing the pair of soldering portions 23c, and the limiting piece 24b of the metal cover 24 and the pair of leg pieces 24c are soldered to the ground pattern, and the soldering portion 23c is soldered. On the signal pattern, the connector socket 20 can be mounted on the circuit board 120.

As shown in FIG. 3, the fitting recess 21a of the connector socket 20 to which the circuit board 120 is mounted is inserted into the connector plug 10 to which the two insulated wires 130 are connected. Until the positioning recess 24a of the metal cover 24 is inserted into the position where the positioning protrusion 15 of the connector plug 10 of FIG. 1 is in a gap fit, the connector plug 10 is connected to the connector socket 20, in the connected state, as shown in FIG. As shown, the contact contact portion 23a of the connection contact 23 projecting from both side faces of the fitting recess 21a is in elastic contact with the contact plate portion 3 of the pressure contact head 2 exposed on both side faces of the plug housing 11, 2 The core wire 130b of the root insulated wire 130 is electrically connected to a corresponding signal pattern of the circuit board 120.

Since the contact contact 2 of the connector plug 10 and the connection contact 23 of the connector socket 20 are located in the insertion direction of the connector plug 10, that is, the side in the fitting recess 21a orthogonal to the front-rear direction, it is not required to be embedded. The connection contact 23 or the pressure contact head 2 is disposed behind the recessed portion 21a, so that the lengths of the connector plug 10 and the connector socket 20 in the front-rear direction can be shortened.

However, the pressure contact head 2 and the connector socket 20 of the connector plug 10 may be employed for the purpose of lowering the height in the vertical direction orthogonal to the connector plug 10 or the circuit board 120 of the connector socket 20. The connection of the connection contacts 23 is formed in the rear of the fitting recess 21a.

Further, in the above-described embodiment, the end portion of the insulated wire 130 is inserted into the wire housing chamber 12, and the connector plug 10 is inserted into the fitting recess 21a. The alignment is the same as that of the side surface of the plug housing 11 inserted from the left and right inner side surfaces of the fitting recess 21a orthogonal to the circuit board 120, and the crimping contact 2 is crimped to the insulated wire 130 orthogonally to the side surface. In the structure of the core wire 130b, the connector plug 10 may be inserted from the vertical direction of the fitting recess 21a.

Further, although the crimping plate portion 4 in which the pair of crimping grooves 4a are formed in the front and rear is formed on one of the press contact heads 2, and the crimping is connected to two places different in the longitudinal direction of the insulated wire 130, It is also possible to form one or three or more crimping grooves 4a.

Further, although the above-described embodiment has been described with the example in which the two insulated wires 130 are connected to the connector plug 10, the connector plug 10 in which only one insulated wire 130 is connected may be used.
