Description

  The present invention relates to a connector, a connector housing, and a method for manufacturing a connector that are used by being connected with, for example, a twisted electric wire.

  2. Description of the Related Art Conventionally, there has been provided a connector in which tips of a plurality of covered electric wires are accommodated in a connector housing. As a covered electric wire used for this connector, a wire using a twisted electric wire has been recently proposed. This twisted electric wire is obtained by twisting (twisting) two covered electric wires. Since the direction of the magnetic field generated from each covered electric wire is reversed due to the twist, the respective covered electric wires can cancel each other's generated magnetic field. Thereby, the twisted electric wire can reduce the influence of electromagnetic induction, and can also reduce crosstalk and external noise.

  Here, the tip end portions of the plurality of covered electric wires are inserted and fixed to the connector housing. In the case of a twisted electric wire, it is difficult to match the positions and directions of the terminals at the tip end portions of the plurality of twisted covered electric wires. Therefore, it is difficult to insert and fix the terminals at the tip end portions at the same time. For this reason, it is necessary to untwist the tip part to some extent and insert the terminals one by one. If it does so, the effect which cancels out the generated magnetic field will not be acquired or will reduce in the part which twisted back, and communication quality will fall.

  In order to prevent this, a terminal processing structure in which an electric wire holding member is attached to a twisted-back portion of a twisted electric wire has been proposed (see Patent Document 1). This structure adjusts the distance between conductors by attaching an electric wire holding member to the untwisted portion so that the covered electric wires in the untwisted portion are brought close to each other. Thereby, it is supposed that impedance can be matched.

  However, according to this structure, there is a problem that a plurality of types of wire holding members must be prepared according to the thickness of each covered wire of the twisted wire. Moreover, since the distance between the conductors of the untwisted portion is adjusted by attaching the electric wire holding member, there is a problem that it takes time to install the electric wire holding member. Moreover, since the part which attaches an electric wire holding member becomes a part from which the covered electric wire has come out from the connector housing, there exists a problem that it is difficult to work. In particular, when a plurality of covered electric wires are attached to the connector housing, there is a problem in that an adjacent covered electric wire that does not require the attachment of the electric wire holding member interferes with the operation of attaching the electric wire holding member.

FIG. 4 is an explanatory diagram for explaining the external appearance of the twisted pair cable 4.

  As shown in FIG. 1, the connector 1 mainly includes a housing cover 2, a housing base 3, and a twisted pair cable 4. Among these, the housing cover 2 and the housing base 3 constitute a connector housing 10.

  As shown in FIG. 2, the housing cover 2 is formed in a substantially quadrangular prism shape that is hollow inside, and one (rear) of the internal storage space 17 is opened, and a plurality of insertion holes 13 are formed on the other (front). Is provided.

  On the upper surface of the housing cover 2, there are provided a guide rail 11 that guides the insertion direction when connecting to a male connector (not shown) and the like, and a retaining protrusion 12 that retains after insertion.

  In the storage space 17 of the housing cover 2, a retaining protrusion 21 is provided on the insertion hole 13 side of the lower surface. The retaining protrusion 21 protrudes to the inside of the storage space 17 (upward in the figure) and retracts when pressed to the outside of the storage space 17 (downward in the figure), and returns to the original position from the retracted position by the elastic force of the material. Energize in the return direction to try. The retaining protrusion 21 prevents the inserted twisted pair cable 4 from coming off.

In addition, a straight guide groove 25 is provided in the storage space 17 of the housing cover 2 from the vicinity of the center of the lower surface toward the opening 18. Further, in the housing space 17 of the housing cover 2, a retaining recess 23 is provided at both ends in the width direction near the opening 18. The retaining recess 23 prevents the inserted housing base 3 from coming off.
The opening 18 of the housing cover 2 is provided with an engagement recess 15 in which wall portions on both sides in the width direction are cut out in a concave shape.

As shown in FIG. 3, the housing base 3 is configured by projecting a plurality of partition plates 32 (32 a and 32 b) side by side on the upper surface of a substantially plate-like support base portion 31.
The partition plate 32 is formed of an external partition plate 32a having a high height on both sides in the width direction, and the other inner side is formed of an internal partition plate 32b having a slightly low height.

  These partition plates 32 are formed in a wall shape that is long in the connecting direction (front-rear direction) of the connector 1, and a plurality (in this example, five) are arranged in parallel at equal intervals in the width direction.

  A storage space 38 for storing the tip of the twisted pair cable 4 is formed between the partition plates 32. The storage space 38 is open at the top and allows the crimp terminal 6 to be attached from top to bottom. The rear of the storage space 38 is also opened, and the covered electric wire 7 of the twisted pair cable 4 is configured to go out of the storage space 38. In addition, a positioning end surface 33 is provided at a lower portion in front of the storage space 38.

  Moreover, the partition plate 32 is divided | segmented in the center vicinity of a connection direction (front-back direction). Thus, there is no problem even if the mounting projection 35 provided in the vicinity of the dividing portion is deformed in the expanding direction (width direction).

  The external partition plate 32a is provided with an engagement projection 34 that projects in the width direction at one end. The engaging protrusion 34 engages with the engaging recess 15 of the housing cover 2 and locks the housing base 3 so as not to enter the housing cover 2 any more.

  In addition, a slit 34 a is provided at the bottom of the external partition plate 32 a near the engagement protrusion 34 so as not to contact the support base 31. Due to the slit 34a, an elastic retaining piece 37 is formed in the lower part of the external partition plate 32a near the engaging projection 34.

  The elastic retaining piece 37 is a substantially rod-shaped part in which the connecting direction front end (front front end) is connected to the support base 31, and a retaining protrusion 37 a is provided on the lower surface. The retaining protrusion 37a is convex downward, the front side is an inclined surface, and the rear side is a vertical surface. As a result, when the housing base 3 is inserted into the housing cover 2, the elastic retaining piece 37 is retracted upward without the retaining protrusion 37a being caught, and when the housing base 3 is inserted deeply, the elastic retaining member 37 is elastically removed by the elastic force of the material. The retaining piece 37 returns downward, and the retaining projection 37a engages with the retaining recess 23 (see FIG. 2) of the housing cover 2.

  The mounting projections 35 are provided symmetrically in the vicinity of the center in the connecting direction (front-rear direction) of each storage space 38. Further, the mounting protrusion 35 is provided at a position between the partition plates 32 arranged in the front-rear direction.

  Both the left and right protrusions 35 of this mounting protrusion 35 protrude upward, and a retaining protrusion 36 that protrudes inward is provided near the upper end. With this mounting projection 35, the crimp terminal 6 of the twisted pair cable 4 can be clamped and prevented from coming off.

  The twisted pair cable 4 is composed of two covered electric wires 5 with terminals. The coated electric wire 5 with a terminal is configured by connecting a crimp terminal 6 to the tip of the coated electric wire 7. The twisted pair cable 4 is configured by alternately twisting the covered electric wires 7 of the covered electric wires 5 with terminals in a spiral shape.

  As shown in FIG. 4A, the crimp terminal 6 of the coated electric wire 5 with a terminal is insulated from a box portion 51 formed in an inner hollow cylindrical shape on the distal end side, a wire barrel 56 that crimps a wire conductor 61, and insulation. It is mainly composed of an insulation barrel 58 for crimping the coating 62. The crimp terminal 6 is an open barrel type terminal that is three-dimensionally configured by punching and bending a copper alloy strip such as brass whose surface is tin-plated (Sn-plated).

  As shown in FIG. 4B, an engagement hole 53 is provided on the bottom surface of the box portion 51, and stabilizers 54 that protrude downward on both sides of the engagement hole 53 are formed symmetrically. . The stabilizer 54 is a plate-like protrusion that protrudes downward, and has a bottom that is horizontal, and both sides that are positioned forward and backward (right and left sides) are formed vertically.

  A contact piece 52 that contacts the inserted male terminal is provided at the front end of the bottom surface of the box portion 51. As shown in FIG. 4C, the contact piece 52 can be manufactured by bending a plate shape. The contact piece 52 bends from the front end of the bottom surface of the box portion 51 upward and backward, and then rises upward and backward from there. It is formed in a mountain shape that descends downward and rearward. The mountain-shaped apex 52a of the contact piece 52 is close to the ceiling surface of the box portion 51, and the end 52b, which is the rear end of the mountain-shaped, is positioned below the apex 52a and above the engagement hole 53. Yes.

  As a result, when the male terminal is inserted from the insertion port 55 provided at the tip of the box portion 51, it contacts the apex 52a and presses downward, and the entire chevron portion of the contact piece 52 tilts and the end portion 52b. Goes down. And since it urges | biases to the direction returned by the elastic force of the contact piece 52, the vertex 52a of the contact piece 52 continues to contact a male type terminal, and the state which supplies electricity favorably is maintained.

The wire barrel 56 and the insulation barrel 58 are formed by bending a plate-like portion in which the bottom portion of the box portion 51 extends to the base side (the covered electric wire 7 side).
The wire barrel 56 is first formed into a U-shaped cross section, and is formed into an M-shape by bending both upper ends inward and downward with the wire conductor 61 housed inside the U-shape. Press 61 firmly and energize.

  The insulation barrel 58 is first formed into a U-shaped cross section, and is formed into an M-shape by bending both upper ends downward inward with the insulating coating 62 housed inside the U-shape. The cover 62 is firmly crimped.

  The covered electric wire 7 includes an electric wire conductor 61 that is a copper core wire in which copper strands are bundled, and an insulating coating 62 that covers the electric wire conductor 61 with an insulating resin.

  In this way, by fixing the wire conductor 61 of the distal end portion 7a of the covered electric wire 7 with the wire barrel 56 and energizing it, and fixing the insulating coating 62 of the distal end portion 7a with the insulation barrel 58, the distal end portion of the covered electric wire 7 The crimp terminal 6 is firmly crimped to 7a.

Next, a method for manufacturing the connector 1 using these housing cover 2, housing base 3, and twisted pair cable 4 will be described.
FIG. 5 shows a perspective view of a state in which the twisted pair cable 4 is attached to the housing base 3, FIG. 6 shows an explanatory view for explaining the structure at the time of attachment by a sectional view, and FIG. 7 shows the housing with the twisted pair cable 4. FIG. 8 shows a perspective view of the base 3 before being inserted into the housing cover 2, FIG. 8 shows a perspective view of the middle of insertion from the bottom side, and FIG. 9 shows a longitudinal sectional view of the completed connector 1.

  As shown in FIG. 5, first, an attachment step is executed in which each crimp terminal 6 of the twisted pair cable 4 is housed in two adjacent housing spaces 38 (see FIG. 3) and attached to the mounting protrusion 35. When attaching the crimp terminal 6, the vertical direction (attachment direction) that is perpendicular to the direction in which the male terminal is inserted into the crimp terminal 6 (longitudinal direction of the crimp terminal 6) with respect to the storage space 38 of the housing base 3. Attach to. Therefore, the two crimp terminals 6 can be attached to the housing base 3 without twisting back the covered wire 7 of the twisted pair cable 4.

  More specifically, as shown in FIG. 6A, a storage space 38 is formed between the mounting protrusions 35 arranged to face each other, and an open portion 38a is provided above the storage space 38. . When the crimp terminal 6 is pushed downward from the opening 38a as shown by an arrow, the mounting projection 35 is primarily deformed in the direction in which the attachment protrusion 35 spreads as shown in FIG. 6B. When the crimping terminal 6 is further pushed in from there, the mounting projection 35 is restored by its own elastic force as shown in FIG. 6C, and the wire barrel 56 of the crimping terminal 6 is prevented from coming off by the retaining projection 36. To do.

  At the time of this attachment, two crimp terminals 6 may be attached to the mounting projections 35 of the respective storage spaces 38 at the same time. However, if it is difficult to align two positions of the crimp terminals 6 in terms of work, they are crimped one by one. The terminal 6 may be attached to the mounting protrusion 35 of the storage space 38. Specifically, as shown in FIG. 3, each crimp terminal 6 of the twisted pair cable 4 is lightly placed on the two storage spaces 38, and the wire barrel 56 of one crimp terminal 6 is finely adjusted in the position direction. After that, it is pushed into the mounting projection 35 and attached to the snapping, and then the wire barrel 56 of the other crimp terminal 6 is finely adjusted in the position direction and then pushed into the mounting projection 35 and attached to the snapping to obtain the mounting state shown in FIG. Can do.

  Even when attaching the crimp terminals 6 to the mounting protrusions 35 one by one in this way, unlike the conventional method of inserting a long distance in the longitudinal direction, it is sufficient to push in a short distance in the thickness direction of the crimp terminal 6. There is no need to twist back the coated wire 7. Therefore, as shown in the figure, the covered electric wire 7 can be attached in a state where the twist of the covered electric wire 7 starts immediately from the rear end of the internal partition plate 32b located between the two crimp terminals 6. Moreover, since it can be attached in this state without twisting back and re-adjusting, the twisted state, that is, the state in which the magnetic fields generated by the respective covered electric wires 7 can be canceled each other can be satisfactorily changed. Can keep.

  At the time of attachment, the crimp terminal 6 is fixed by being prevented from being detached by the retaining protrusion 36 by being fitted between the mounting protrusions 35 on which the wire barrel 56 is opposed. The position in the width direction of the crimp terminal 6 is regulated by the two mounting projections 35, and the position in the vertical direction is regulated by the retaining projection 36 so that the crimp terminal 6 does not come out upward.

  In particular, the height from the bottom surface of the storage space 38 to the retaining projection 36 is substantially the same as the height from the bottom surface of the wire barrel 56 to the contact portion with the retaining projection 36, thereby the crimp terminal 6. Is firmly fixed so that there is no vertical displacement. Further, in this state, the bottom surface of the box portion 51 and the bottom surface of the insulation barrel 58 are in contact with the bottom surface of the storage space 38, so that the crimp terminal 6 is firmly fixed without swinging with respect to the housing base 3.

  Moreover, since the space | interval of the adjacent partition plates 32 (32a, 32b) is formed to the extent which is substantially the same as the width | variety of the box part 51 of the crimp terminal 6, or the position of the left-right direction of the box part 51 is a partition. It is also restricted by the plate 32.

  Further, since the stabilizer 54 of the box portion 51 comes into contact with the positioning end surface 33 and is locked, the position of the crimp terminal 6 in the front-rear direction is fixed thereby.

  In addition, since the insulation barrel 58 and the distal end portion 7a of the covered electric wire 7 to which the insulation barrel 58 is crimped are sandwiched between the partition plates 32 at both ends in the width direction, the position is regulated so as not to move in the left-right direction. .

  In this way, the wire barrel 56 located near the center of the crimp terminal 6 is sandwiched by the mounting projections 35 and fixed so as not to move in the width direction and the mounting direction (vertical direction), and the bottom surface of the crimp terminal 6 (in particular, The crimp terminal 6 is prevented from swinging in the mounting direction (vertical direction) when the bottom surface of the box portion 51 and the bottom surface of the insulation barrel 58 are in contact with the top surface of the support base portion 31 (that is, the floor surface of the storage space 38). Further, both sides of the crimp terminal 6 (particularly both sides of the box portion 51 and both sides of the insulation barrel 58) are in contact with or close to the partition plate 32 so that they do not swing in the width direction. Since the stabilizer 54 of 6 is brought into contact with the positioning end surface 33 of the housing base 3 so as not to move in the front-rear direction, the crimp terminal 6 is It is firmly fixed to the housing base 3 also stable so as not to swing and to move shift direction.

  Next, a covering step for inserting the housing base 3 to which the twisted pair cable 4 is fixed in this way into the storage space 17 from the opening 18 of the housing cover 2 is executed as shown in FIG. At this time, since the width of the housing base 3 is the same as or slightly narrower than the width of the storage space 17 of the housing cover 2, the side surfaces of the left and right external partition plates 32 a are in contact with the side walls of the storage space 17 and inserted smoothly. Is done. Further, since the height of the housing base 3 (particularly the height of the external partition plate 32a) is the same as or slightly lower than the height of the storage space 17 of the housing cover 2, the bottom surface of the housing base 3 is the floor surface of the storage space 17. The upper surface of the housing base 3 (the upper surface of the external partition plate 32a) comes into contact with the ceiling surface of the storage space 17 and is smoothly inserted.

  At the time of insertion, as shown in FIG. 8, a guide rail 39 formed on the bottom surface of the housing base 3 so as to be long in the front-rear direction at the center position in the width direction is formed on the floor surface of the storage space 17 of the housing cover 2. Since it is guided by the guide groove 25, it can be inserted smoothly and prevented from being inserted upside down.

  When the housing base 3 is completely inserted into the housing space 17 of the housing cover 2, the engaging protrusion 34 of the housing base 3 comes into contact with the engaging recess 15 of the housing cover 2 and is locked so that it cannot be inserted any more. Is done.

  When inserted up to this state, the retaining protrusion 37 a provided on the elastic retaining piece 37 of the housing base 3 enters the retaining recess 23 of the housing cover 2. Then, as shown in the longitudinal sectional view of FIG. 9, the vertical surface provided behind the retaining protrusion 37 a comes into contact with the retaining locking surface 23 a of the retaining recess 23 and is securely retained.

  Further, when inserted to the back in this way, the retaining hole 53 provided in the engagement hole 53 provided in the crimp terminal 6 of the twisted pair cable 4 so as to protrude from the floor surface of the storage space 17 of the housing cover 2 is provided. The upper end of the protrusion 21 enters and the crimp terminal 6 is fixed. Thereby, the crimp terminal 6 is directly fixed to the housing cover 2, and the strength can be increased, and the positional accuracy of the insertion port 55 of the crimp terminal 6 with respect to the insertion hole 13 of the housing cover 2 can be stabilized.

  More specifically, when the male terminal is inserted in the direction indicated by the arrow Y, it strikes the contact piece 52 of the crimp terminal 6 and is pressed in the direction in which the twisted pair cable 4 and the housing base 3 are extracted. At this time, if there is no retaining protrusion 21, the stabilizer 54 of the crimp terminal 6 is locked while pressing the positioning end surface 33 of the housing base 3, and the retaining protrusion 37 a of the housing base 3 is fixed to the retaining locking face 23 a. It is locked while being pressed and is prevented from coming off only by this structure. Then, the pressing force applied to the crimp terminal 6 is received by the housing cover 2 via the housing base 3, and there is a possibility that a force is applied in various directions during that time, leading to a failure. Further, since the distance from the contact piece 52 to which the crimp terminal 6 is pressed to the retaining locking surface 23a of the housing cover 2 is long, it may cause deformation or the like therebetween.

  On the other hand, by directly fixing the crimp terminal 6 to the housing cover 2 by the retaining protrusion 21, the force applied to the crimp terminal 6 by the insertion of the male terminal can be directly received by the housing cover 2. In addition, since the crimping terminal 6 is fixed by the retaining protrusion 21 provided at a position very close to the contact piece 52 to be pressed, it is possible to prevent deformation and malfunction due to force applied in various directions. .

  With the above-described configuration and manufacturing method, the crimp terminal 6 of the twisted pair cable 4 can be easily fixed to the housing base 3, and deterioration in communication quality can be prevented. That is, since the crimp terminal 6 can be attached to the housing base 3 in the thickness direction, it can be attached without twisting back where twisting is indispensable if it is inserted in the longitudinal direction as in the prior art. .

  Further, since the mounting protrusions 35 are arranged side by side, the crimp terminals 6 of the twisted pair cable 4 can be attached in the thickness direction while being in a side-by-side state, and it is possible to easily realize the attachment without twisting back the covered electric wire.

  Further, since the mounting protrusion 35 regulates the position of the crimp terminal 6 in the width direction, it is possible to easily attach and position the crimp terminal 6 in the vertical direction that is the thickness direction. In particular, since the wire barrel 56 of the crimp terminal 6 is clamped by the mounting protrusion 35, the crimp terminal 6 can be attached to the housing base 3 with a fitting type, and both the ease of work and the stability of the attachment after the fitting are achieved. be able to.

  Further, since the mounting protrusion 35 has elasticity, various types of twisted pair cables 4 having different thicknesses of the wire barrel 56 depending on the thickness of the covered electric wire 7 can be attached to the same housing base 3.

  Further, since the attachment protrusion 35 is provided with the retaining protrusion 36, when the crimp terminals 6 of the twisted pair cable 4 are attached to the attachment protrusion 35 one by one, they are attached first during the subsequent operation of attaching the crimp terminals 6. It is possible to prevent the crimp terminal 6 from coming out of the mounting protrusion 35 and to facilitate the mounting operation.

  In addition, the longitudinal position of the crimp terminal 6 is regulated by the engagement hole 53 of the crimp terminal 6 and the retaining protrusion 21 of the housing base 3, the stabilizer 54 of the crimp terminal 6, and the internal partition plate 32b of the housing base 3. When the mating male terminal is inserted and connected, the position of the crimp terminal 6 can be prevented from shifting in the longitudinal direction.
