Description

  The present invention relates to a connector for electrically connecting a discrete wire to a circuit board.

  Conventionally, a male terminal having a tab-shaped contact piece at the tip is attached to the end of the discrete wire, and the male terminal is stored in each terminal storage chamber of a female connector housing having a plurality of terminal storage chambers in parallel. A female connector is formed by mounting a male connector housing containing female terminals on a printed circuit board to form a male connector, and these connectors are coupled to each other via both terminals. In general, a connector that electrically connects a discrete wire to a circuit on a printed circuit board is known.

  In this type of connector, for example, various in-vehicle electrical devices are required to further reduce the size of the connector because of a demand for space saving.

  In order to reduce the pitch of the terminal arrangement, the terminals themselves have been downsized. However, as the downsizing progresses, there are cases where it is difficult to reduce the pitch due to the wire diameter of the discrete wire. . That is, as for a terminal (in the case of a male terminal) attached to a discrete wire, for example, as shown in FIG. 13, a pair of wire barrels 52 and a pair of insulation barrels 54 are arranged behind a tab-shaped contact piece 51. The insulation barrel 54 is configured to be crimped (clamped) to the conductor portion 50a with the wire barrel 52 exposed at the end of the discrete wire, and to the covering portion behind the conductor barrel 50a. Since the barrel 54 is crimped so as to hold the discrete wire 50 from the outside of the coating to such an extent that it can bear a part of the tensile force acting on the discrete wire 50, as shown in FIG. Wide w) is larger than the diameter of the discrete wire 50. Therefore, even if the terminal itself is reduced in size, there are cases where it is difficult to proceed with the narrowing of the pitch due to the restriction of the crimp width w.

  It is conceivable to crimp the insulation barrel 54 so that the crimping width (crimp wide w) is reduced. In this case, the discrete wire 50 is deformed in the crimping height (crimp height h) direction. Since the insulation barrel 54 is easily opened, there is a problem that it is difficult to properly press-bond the insulation barrel 54 to the discrete wire 50.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the size of a connector by more effectively achieving the above-described narrowing of the terminal arrangement.

In order to solve the above-described problems, a connector according to claim 1 of the present invention is configured such that a plurality of first terminals mounted on the end of the discrete wire are arranged in the housing by crimping an insulation barrel to the discrete wire. A first connector housed in a closed state and a second connector housed in a housing with a second terminal that can contact the first terminal, and the terminals of each connector by fitting the housings together In the connectors that contact each other, the insulation barrel was crimped to the discrete wire so that the crimp wide (crimp molding width) of the insulation barrel was flatter than the crimp height (crimp molding height). In the state, the first terminal is attached to the discrete wire, and adjacent terminals are connected to the insulator. Deployment barrel is housed each first terminal to the first connector housing so as to be aligned in the direction of the crimp height of said first connector housing, while holding the discrete lines of said first terminal The first terminal can be accommodated in any posture of the side facing the one side in the terminal arrangement direction or the posture facing the opposite side, and the first terminal is a housing in any of the above postures. A contact portion with respect to the second terminal is formed so as to be able to come into contact with the second terminal even when housed therein .

According to this connector, since the first terminal is housed in the housing in a state where the first terminals are arranged in the direction of the crimp height of the insulation barrel as described above for the first connector holding the discrete wire. The insulation barrel is crimped to the discrete wire so that the crimp width of the insulation barrel is not limited by the crimp width of the insulation barrel and the crimp width is flatter than the crimp height. Therefore, the occupied space in the terminal arrangement direction of the crimping portion is reduced. Therefore, the pitch of the terminal arrangement can be effectively reduced. In addition, since the insulation barrel is pressure-bonded to the discrete wire so that the crimp width is in a flat state larger than the crimp height, the insulation barrel can be appropriately pressure-bonded to the discrete wire. In addition, since the degree of freedom in the storage direction of the first terminal with respect to the housing of the first connector is improved, it is possible to effectively prevent erroneous work while improving the assembly workability of the first connector.

  For the first connector, the insulation barrel is connected to the discrete wire in a flat state where the crimp width of the insulation barrel is larger than the crimp height and the crimp height is smaller than the wire diameter of the discrete wire. It is preferable that it is crimped | bonded with respect to (Claim 2).

  According to this configuration, the pressure-bonded portion of the insulation barrel is in a flat state smaller than the wire diameter of the discrete wire, so that the pitch can be reduced more effectively.

In this case, in the case where a tab-shaped contact piece is provided as the contact portion at the tip of the first terminal, the tab-shaped contact piece is arranged in a direction orthogonal to the terminal arrangement direction in a state where the first terminal is housed in the housing. It may have a pair of unit contact pieces parallel to each other (claim 3 ).

  In other words, when the degree of freedom of the insertion posture of the first terminal with respect to the housing is increased as described above, for example, when the contact height position of the second terminal with respect to the first terminal is shifted from the center of the connector, Depending on the storage posture, there may be a case where a gap is generated between the first terminal and the second terminal, and the contact between the two terminals is not successful. In such a case, by providing the pair of unit contact pieces as the contact pieces as described above, the gap is eliminated and the first terminal is appropriately set even if the first terminal is housed in the housing in any posture. It is possible to make contact with the second terminal.

In this case, the tab-shaped contact piece is formed in a U-shaped cross section having the pair of unit contact pieces and a connecting portion for connecting the unit contact pieces in the arrangement direction thereof. The housing includes a restraining portion that is inserted between the pair of unit contact pieces in a state where the first terminal is accommodated and restrains the tab-like contact pieces in the arrangement direction of the unit contact pieces. Preferred (claim 4 ).

  According to this connector, it is possible to prevent the tab-like contact piece from floating when the connector is connected, and it is possible to improve the contact reliability between the first terminal and the second terminal.

In this case, the restraining portion is inserted between the pair of unit contact pieces from the tip side of the tab-like contact piece, so that the first terminal is accommodated in the housing of the first connector in any of the above postures. Even so, it is preferable that the tab-like contact piece is configured to be constrained in the arrangement direction of the unit contact pieces (claim 5 ).

  According to this configuration, even when the first terminal is housed in the housing in any of the above postures, it is possible to reliably prevent the tab-like contact piece from being lifted when the connector is connected.

According to the connectors according to claims 1 to 5 of the present invention, the terminal arrangement pitch setting of the first connector that holds the discrete wire is not subject to the restriction due to the crimp width of the insulation barrel as in the prior art. The array can be narrowed more effectively. Thus, downsizing of the entire connector in the terminal arrangement direction can be achieved through narrowing the pitch of the terminal arrangement of the first connector.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic perspective view for explaining an embodiment of a connector according to the present invention, in which a part of a terminal and the like is drawn out. In this figure, C2 is a board-side connector (second connector), which is fixed in a mounted state on the surface of the circuit board P. C1 is a wiring material side connector (first connector), and is configured to connect the discrete wire 5 to the circuit board P by being coupled to the board side connector C2.

  The board-side connector C2 has a connector housing 10 (hereinafter abbreviated as “housing 10”) that is elongated in the width direction and includes a fitting recess 10a for the wiring material-side connector C1.

  As shown in FIGS. 2 and 3, the housing 10 has a large number of terminal storage chambers 13 formed in parallel in the width direction (left and right direction in FIG. 2) and in two upper and lower stages. As shown in the figure, the upper and lower terminal storage chambers 13 are alternately provided in a state shifted from each other by a half pitch, whereby the terminal storage chambers 13 are arranged in a staggered pattern as a whole housing.

  Each terminal storage chamber 13 stores a terminal 12 (second terminal). The terminal 12 has a fork-like (U-shaped) connecting portion composed of a connecting bending piece 14a that can be bent and displaced in the vertical direction and a support portion 14b on the lower side thereof on the front side (the left end in FIG. 3). A female terminal having a leg portion 14c on the side is housed by being inserted into the terminal housing chamber 13 from the rear side of the housing 10, and the leg portion 14c is soldered to a fixing land of the circuit board P. By being attached, they are electrically connected to the circuit (pattern) on the substrate. In addition, the terminal 12 housed in the upper stage of the upper and lower terminal housing chambers 13 has a leg portion 14c that is longer than the lower part, so that it can be soldered to the circuit board P. It has become.

  Fixing brackets 15A and 15B for fixing the board-side connector C2 (housing 10) to the circuit board P are inserted into both ends of the housing 10 in the width direction.

  These fixing brackets 15A and 15B have legs 16 as shown in FIGS. 1, 2, and 4 (only the fixing bracket 15A is shown), and these legs 16 are soldered to the circuit board P. Thus, the housing 10 is fixed to the circuit board P.

  Each fixing bracket 15A, 15B has a hook 17a at its front end and is integrally formed with a locking piece 17 (see FIG. 4) which can be flexed and displaced in the width direction within the housing 10, and is fitted with a connector. At the same time, the engaging piece 17 is configured to be engaged with a housing 20 described later of the wiring member side connector C1 to lock both the connectors in the fitted state. That is, these fixing brackets 15A and 15B have a structure having a connector locking function.

  Note that the locking pieces 17 of the fixing brackets 15A and 15B are offset vertically as shown in FIG. This is a contrivance for compactly fitting each of the fixing brackets 15A and 15B in the housing 10, thereby achieving space saving in the width direction of the board-side connector C2 as will be described later.

  On the other hand, the wiring member side connector C1 includes a connector housing 20 that is elongated in the width direction (hereinafter abbreviated as the housing 20), as shown in FIGS. A plurality of terminal storage chambers 22 are provided in the housing 20 in parallel in the width direction and in two upper and lower stages, and a terminal 5 (first terminal) attached to the tip of the discrete wire 3 is provided in each terminal storage chamber. 22.

  The terminal storage chambers 22 are alternately provided with the upper and lower ones being shifted by a half pitch in the width direction. As a result, the terminal storage chambers 22 are staggered as a whole as in the housing 10 of the board-side connector C2. It is an array.

  On the front side of the housing 20, that is, on the front end surface in the connector connecting direction, a pair of tongue-shaped terminal support portions 24 project from the upper and lower terminal storage chambers 22.

  These terminal support portions 24 support the later-described contact pieces 5b of the terminals 5 accommodated in the respective terminal storage chambers 22. On the upper surface side of each terminal support portion 24, as shown in FIG. 5 and FIG. A plurality of support grooves 26 that open upward and communicate with the inside of the terminal storage chamber 22 are juxtaposed in the width direction. In addition, a protrusion 27 for preventing the contact piece 5b of the terminal 5 from floating up is provided on the front end wall 26a of each support groove 26 so as to protrude rearward (leftward in FIG. 6).

  The discrete wire 3 is, for example, a single wire in which a coating (insulating layer) is formed on the outer periphery of a stranded wire, and the terminal 5 is attached to the tip thereof as described above.

  As shown in FIG. 7A, the terminal 5 is a male terminal provided with an electric wire holding portion 5a for holding the discrete wire 3 and a tab-like contact piece 5b provided on the tip side thereof.

  The electric wire holding part 5a is provided with a pair of wire barrels 32 and a pair of insulation barrels 34 that are arranged on both sides of the bottom plate 30 of the terminal 5 in the front-rear direction.

  The contact piece 5b includes a connecting portion 37 that extends in the front-rear direction continuously to the bottom plate 30, and a pair of unit contact pieces 36a that are elongated in parallel in the front-rear direction and are parallel to the barrels 32, 34. 36b and a U-shaped cross section. In addition, a hook 38 for locking the terminal 5 to the housing 20 is integrally formed at the base end of each unit contact piece 36a, 36b.

  As shown in the figure, the terminal 5 is attached to the discrete wire 3 by removing the coating at the end portion of the discrete wire 3 so that the conductor 3a is exposed to the outside, and the wire barrel 32 is attached to the portion of the conductor 3a. The insulation barrel 34 is respectively crimped to the covering portion on the rear side. Here, the wire barrel 32 is firmly crimped (clamped) so that the tip of the wire barrel 32 bites into the conductor 3a in order to ensure conduction performance and holding force. On the other hand, the insulation barrel 34 holds the discrete wire 3 from the outside of the covering portion so that the tips thereof face each other, and is crimped so that the crimped portion becomes flat. Specifically, as shown in FIG. 8A, the crimp width w (crimping molding width) is sufficiently larger than the crimp height h (crimping molding height), and the crimp height h is the diameter of the discrete wire 3. An insulation barrel 34 is pressure-bonded to the discrete wire 3 so as to be smaller than d (see FIG. 8B). Thereby, the whole electric wire holding part 5a including the discrete wire 3 is made flat.

  The terminals 5 attached to the distal ends of the discrete wires 3 are stored in the terminal storage chambers 22 as described above. The terminal 5 is stored in the terminal storage chamber 22 as shown in FIG. 7B. The terminal 5 faces sideways, that is, the crimp height h of the insulation barrel 34 is in the terminal storage chamber as shown in FIGS. In this state, the terminals 5 are turned sideways so as to face the arrangement direction (width direction) of the terminals 22, and the terminals 5 are inserted into the terminal storage chamber 22 from the rear of the housing 20 in this state. Specifically, while the terminal 5 is inserted into the terminal storage chamber 22, the tip (contact piece 5b) protrudes forward from the terminal storage chamber 22 and is inserted into the support groove 26 of the terminal support portion 24. The terminal 5 is inserted into the housing 20 until the tip comes into contact with the front end wall 26 a of the support groove 26. In this way, as shown in FIG. 6 (b), the protrusion 27 formed on the front end wall 26a of the support groove 26 is inserted between the unit contact pieces 36a, 36b of the contact piece 5b, and each unit. The hooks 38 formed on the contact pieces 36 a and 36 b engage with the outlet (front opening) edge of the terminal storage chamber 22. As a result, the contact piece 5 b of the terminal 5 is exposed to the outside, and the terminal 5 is housed and held in the housing 20 together with the discrete wire 3 in a state where the tip of the contact piece 5 b is restrained in the vertical direction by the protrusion 27.

  The terminal storage chamber 22 of the housing 20 has a substantially symmetric cross-sectional shape in the vertical and horizontal directions, and the terminal 5 is in either the left or right orientation, that is, the holding surface side of the discrete wire 3 in the terminal 5 is the terminal storage chamber 22 ( The terminal 5 can be inserted even in the state where the support groove 26) faces either one side or the other side (left side or right side in FIGS. 9 and 10). Further, as shown in the figure, the terminal support portion 24 also appropriately restrains the displacement of the contact piece 5b in the vertical direction even when the terminal 5 is inserted into the terminal storage chamber 22 in any of the above directions. The protrusions 27 and the like are formed so that the height position of the unit contact pieces 36a, 36b located on the upper side can be kept constant. That is, even if the terminal 5 is inserted in any direction, the counterpart terminal 12 can reliably contact either one of the unit contact pieces 36a and 36b.

  As shown in FIGS. 1 and 5, locking portions 28 corresponding to the locking pieces 17 of the board-side connector C2 are integrally formed on both sides of the housing 20 in the width direction.

  In the configuration of the connectors C1 and C2 as described above, in order to connect both the connectors C1 and C2 and connect the discrete wire 3 to the circuit board P, as shown in FIGS. 11 (a) and 12 (b), The wiring material side connector C1 is opposed to the fitting concave portion 10a of the board side connector C2, and the both terminal support portions 24 of the wiring material side connector C1 are inserted into the fitting concave portion 10a from the distal end side. More specifically, of the upper and lower two-stage terminals 12 housed in the board-side connector C2, the upper terminal support portion of the wiring material-side connector C1 is interposed between the connecting flexure piece 14a of the upper terminal 12 and the support portion 14b. 24, the housings of both connectors C1 and C2 are fitted together while the lower terminal support portion 24 of the wiring material side connector C1 is inserted between the connecting flexure piece 14a and the support portion 14b of the terminal 12 at the lower stage. . In this way, as the housing 20 is inserted, the locking piece 17 of the board-side connector C2 is pushed outward and the connectors C1 and C2 are brought into a completely fitted state as shown in FIG. Thus, the hook 17a of the locking piece 17 engages with the locking portion 28 of the housing 20, and as a result, both the connectors C1 and C2 are locked in the fitted state. When the connectors C1 and C2 are in a completely fitted state in this way, as shown in FIG. 11B, the mating terminal 12 is connected to the contact piece 5b of the terminal 5 attached to each discrete wire 3. The connecting bending pieces 14a are in contact with each other, and more precisely, the connecting bending pieces 14a of the mating terminal 12 are in contact with the unit contact pieces 36a (or 36b) located on the upper side of the unit contact pieces 36a and 36b. As a result of this contact, each discrete line 3 is connected to the circuit on the circuit board P via the corresponding counterpart terminal 12.

  According to the configuration of the connector according to the present invention as described above, the crimp height h of the insulation barrel 34 is smaller than the crimp wide w (smaller than the diameter d of the discrete wire 3) as described above with respect to the wiring material side connector C1. ) The terminal 5 is mounted on the discrete wire 3 so as to be in a flat state, and further stored in the housing 20 in a state in which the terminal 5 is placed sideways so that the crimp height h of the insulation barrel 34 faces the direction in which the terminal storage chamber 22 is arranged. In other words, the wiring member side connector C1 is configured so that the terminal 5 is accommodated in the housing 20 in a state where the terminals 5 are arranged in the direction of the crimp height h of the insulation barrel 34. As a result, multiple terminals are stored side by side in the crimp-wide direction of the insulation barrel. There is an effect that conventional can effectively pitch the comparison when the terminal sequence this kind of connector that.

  That is, in the conventional connector, the insulation barrel of the terminal is crimped so as to be held from the outer side of the sheath while maintaining the cross-sectional shape of the discrete wire, so that the crimp width ( In other words, it is difficult to effectively reduce the pitch because it is restricted by the wire diameter of the discrete wire 3, but in the wiring material-side connector C 1, the terminals 5 are arranged in the direction of the crimp height h of the insulation barrel 34. Therefore, there is no restriction due to the crimp width w when setting the pitch between terminals. In addition, the insulation barrel 34 is crimped to the discrete wire 3 in a flat state in which the crimp height h is smaller than the crimp wide w, specifically smaller than the wire diameter of the discrete wire 3. The occupied space in the terminal arrangement direction of the crimp portion is reduced. Therefore, it is possible to effectively reduce the pitch of the terminal arrangement. In addition, since the insulation barrel 34 is crimped so that the crimp width w is flatter than the crimp height h, the insulation barrel 34 is also properly crimped to the discrete wire 3.

  Therefore, if the same number of discrete wires 3 are held, the terminal arrangement can be made narrower than the conventional connector of this type, and accordingly, the wiring material side connector C1 and the board side connector C2 are correspondingly reduced. Can be miniaturized.

  Further, in this wiring material side connector C1, as shown in FIGS. 9 and 10, the terminal 5 is in any direction left and right, that is, the holding surface side of the discrete wire 3 of the terminal 5 is the terminal storage chamber 22 (support groove). 26), the terminal 5 can be stored in the terminal storage chamber 22 regardless of whether it is facing one side or the other side of the arrangement direction, and the vertical displacement of the contact piece 5b is appropriately restrained to Since the housing 20 is formed so that the height position of the contact piece 36a, 36b located on the upper side can be kept constant, that is, the terminal 5 can be properly brought into contact with the terminal 12, the wiring member When the side connector C1 is assembled, the workability can be improved and the occurrence of erroneous work can be effectively prevented.

  Further, by utilizing the fact that the contact piece 5b of the terminal 5 has a U-shaped cross section provided with the pair of unit contact pieces 36a and 36b as described above, a projection 27 is provided on the terminal support portion 24 and this is used as a unit. Since the contact piece 5b is constrained in the vertical direction by being inserted between the contact pieces 36a and 36b to prevent the contact piece 5b from being lifted, the connecting flexible piece 14a of the mating terminal 12 The contact piece 5b can be smoothly and reliably inserted between the support part 14b and the contact piece 5b can be brought into contact with the connecting bending piece 14a. Therefore, the contact reliability between the terminals can be improved.

  The board-side connector C2 has the following effects. That is, in the board-side connector C2, the locking pieces 17 are provided on the fixing brackets 15A and 15B, respectively, and these locking pieces 17 are configured to be engaged with the housing 20 of the wiring material-side connector C1. In this embodiment, as shown in FIG. 2, as a result of the respective locking pieces 17 being offset vertically, there is an effect that space saving of the board-side connector C2 is achieved. More specifically, in the housing 10 of the board-side connector C2, as shown in the figure, the arrangement of the upper terminal storage chambers 13 is shifted to the left with respect to the arrangement of the lower terminal storage chambers 13, and this shift Accordingly, the locking piece 17 of the lower terminal storage chamber 13 is provided in the left fixing bracket 15A, and the locking piece 17 of the upper terminal storage chamber 13 is provided in the locking piece 17 of the right fixing bracket 15B. Is provided. That is, due to the lateral displacement of the terminal storage chamber 13 as described above, the upper terminal storage chamber 13 is arranged at the right end of the housing 10, and the lower terminal storage chamber 13 is arranged at the left end of the housing 10. Each has a dead space. Therefore, in the wiring material side connector C1, the locking piece 17 is provided in each of the fixing brackets 15A and 15B so that the locking piece 17 is positioned in the dead space, thereby sufficiently securing the bending allowance of the locking piece 17. However, both the fixing brackets 15A and 15B can be accommodated in the housing in a compact manner. Therefore, space saving of the board side connector C2 is achieved in this respect.

  The board-side connector C2 and the wiring material-side connector C1 described above are examples of the embodiment of the connector according to the present invention, and specific configurations thereof can be appropriately changed without departing from the gist of the present invention. is there.

  For example, in the above embodiment, the present invention is applied as a connector configuration when the discrete wire 3 is connected to the circuit board P. Of course, the present invention may also be applied as a connector configuration for connecting discrete wires. it can.

  Further, in the above embodiment, the terminal 5 of the wiring material side connector C1 has a configuration in which the pair of unit contact pieces 36a and 36b are provided on the contact piece 5b. Of course, the shape of the contact piece 5b is this. In other words, the shape may be any shape as long as the contact piece 5b can properly contact the counterpart terminal 12 regardless of the orientation of the terminal 5 stored in the terminal storage chamber 22. Good.
