Description

  The present invention relates to a connector, and more particularly to a connector provided with an electric wire holding member for holding an electric wire connected to a terminal accommodated in a connector housing.

  Conventionally, many electronic devices are mounted on automobiles, and wire harnesses for transmitting electric power, electric signals, and the like are connected to these electronic devices. This wire harness has a plurality of electric wires and connectors attached to the ends of these electric wires. The connector has a terminal connected to the terminal of each electric wire and a housing in which a housing portion for these terminals is formed.

  As shown in FIG. 10, in this type of connector, an opening end 83 of the terminal accommodating portion 82 is formed on the housing end surface 81 on the back side of the housing 80. A plate-like member 85 is formed in the longitudinal direction of the terminal 84, and the end of the electric wire 86 is crimped to the plate-like member 85. The terminal 84 to which the electric wire 86 is connected is inserted into the terminal accommodating portion 82 from the open end 83 and is prevented from being detached by the lance 87 of the terminal accommodating portion 82, and the back surface of the plate-like member 85 is the inner wall surface 88 of the terminal accommodating portion 82. Contained in contact with. The electric wires 86 drawn out from the respective open ends 83 are bent in a predetermined direction and are bundled into one electric wire bundle 90 by a binding tool 89 such as an adhesive tape.

  The electric wire bundle 90 is routed to an electric wire holding member 92 that is located on the housing end surface 81 side of the housing 80 and extends from the side surface portion 91 of the housing 80 in a direction substantially orthogonal to the terminal accommodating portion 82. The wire bundle 90 routed to the wire holding member 92 is wound around and fixed to the wire holding member 92 by a binding tool (not shown) (see, for example, Patent Document 1).

JP 2004-349023 A

  By the way, in this type of connector, in order to reduce the size of the connector, the distance between the wiring surface of the electric wire holding member and the housing end surface is set small. For this reason, the electric wire extracted from the open end of the connector is greatly curved during wiring. The stress generated in the electric wire by this bending acts as an external force on the connection portion between the electric wire and the terminal.

  In the case of the terminal accommodating portion 82 in FIG. 10, an inner wall surface 88 that supports the terminal 84 in the longitudinal direction is provided on the side opposite to the electric wire holding member 92 (right side in FIG. 10). For this reason, for example, when the electric wire 86 is greatly curved as indicated by a dotted line, the terminal 84 is pressed against the inner side of the terminal accommodating portion 82, that is, the electric wire holding member 92 side by the stress generated in the electric wire 86. For this reason, there is a possibility that the terminal 84 may be inclined or loose.

  Further, when the terminal 84 is pressed against the electric wire 86 in this way, an external force in a direction of pulling away from the plate-like member 85 acts on the electric wire 86 crimped to the terminal 84. For this reason, an excessive load (stress) is concentrated on a part of the electric wire 86, which may damage the electric wire 86.

  This invention is made | formed in view of such a problem, and makes it a subject to suppress that a load concentrates on an electric wire while hold | maintaining a terminal stably.

  In order to solve the above problems, a connector according to the present invention includes a housing in which a terminal accommodating portion for accommodating a terminal to which an electric wire is connected is formed, and a housing end surface on which an open end of the terminal accommodating portion is located. And a wire holding member that is formed so as to protrude from the side surface portion in a direction crossing the terminal accommodating portion, and the terminal is a contact point that contacts the mating terminal on one end side in the longitudinal direction of the plate-like member to which the electric wire is crimped and connected. And a terminal housing portion is formed with an inner wall surface that is in contact with the back surface of the plate-like member opposite to the electric wire, and the inner wall surface is positioned on the electric wire holding member side. .

  According to this, even if an external force due to the bent electric wire acts on the terminal and the terminal is pressed against the electric wire holding member, the inner wall surface in contact with the plate-like member is provided on the electric wire holding member side of the terminal. The terminal can be stably held by the inner wall surface. Further, even if an external force due to the bent electric wire acts on the terminal, the load is concentrated on the electric wire because only the external force in the direction of pressing the plate member acts on the electric wire crimped to the terminal. Can be suppressed.

  Here, the electric wire holding member is covered with a cylindrical corrugated tube in a state where the electric wires are arranged in the longitudinal direction, and the inner peripheral surface of the corrugated tube has an annular crest and an annular trough as axes. The electric wire holding member is formed alternately in the direction, and the cross section perpendicular to the longitudinal direction is formed in a semicircular arc shape, and at its tip part, a locking projection protruding from both side edges in the width direction is provided. The protrusion is formed so as to be engageable with a valley portion of the corrugated tube.

  According to this, the corrugated tube can be locked to the electric wire holding member by engaging the locking protrusion with the valley of the inner peripheral surface of the corrugated tube. Therefore, in the operation of fixing the corrugated tube to the electric wire holding member (the operation of winding the tape around the outer peripheral surface of the corrugated tube), it is possible to prevent the corrugated tube from being displaced and the corrugated tube from falling off the electric wire holding member. Moreover, since the cross section of the electric wire holding member is formed in a semicircular arc shape and abuts with the inner peripheral surface of the corrugated tube in the circumferential direction, the work of winding the tape around the outer peripheral surface of the corrugated tube can be performed efficiently.

  Further, in this case, the locking projection is formed with a slope portion that narrows the leading end side from which the locking projection protrudes on the side surface opposite to the housing.

  According to this, when the electric wire holding member is inserted into the corrugated tube, the inclined surface portion of the locking projection can be brought into contact with the inner peripheral surface of the corrugated tube. The corrugated tube can be prevented from being damaged by the projections coming into strong contact with the inner peripheral surface of the corrugated tube.

  Further, a stepped portion is provided on the peripheral edge of the housing end surface, and when the stepped portion is positioned below the opening end, a first inclined surface is formed on the side surface located above the stepped portion. The first inclined surface is inclined downward toward one end of the inclined surface.

  According to this, when water droplets adhere to the housing end surface due to condensation or the like, the water droplets that have flowed down to the step portion along the housing end surface flow down along the first inclined surface and are drained from one end. Thereby, since it can suppress that a water droplet accumulates on a housing end surface, it can prevent that a water droplet penetrate | invades into a housing from an opening end, and can prevent the short circuit between terminals.

  Further, the electric wire holding member is formed to have a base end portion raised from the end surface of the housing and a wiring portion extending from the base end portion in a direction intersecting the terminal accommodating portion, and the wiring portion is horizontally disposed. When facing in the direction, a second inclined surface is formed on the side surface located above the base end, and the second inclined surface is inclined downward toward one end of the inclined surface.

  According to this, since the water droplet adhering to the end surface of the housing can be drained along the second inclined surface, similarly to the first inclined surface, a short circuit between the terminals can be prevented.

  ADVANTAGE OF THE INVENTION According to this invention, while holding a terminal more stably, it can suppress that a load concentrates on an electric wire.

It is ensured that the female connector 11 and the male connector 12 are properly fitted to each other by attaching the CPA 16.

  FIG. 2 shows an appearance of the female connector 11 as seen from the back (rear). The housing end surface 18 is formed with a plurality of opening ends 26 that serve as entrances and exits of the female terminal accommodating portion 20, and the electric wires 14 connected to the female terminals 15 are drawn out from the opening ends 26. On the peripheral edge of the housing end surface 18, a stepped portion 27 and finger contact portions 28 and 29 are formed so as to protrude. The stepped portion 27 has a trapezoidal cross section and is provided on the upper end of the housing end surface 18. A plurality of opening ends 26 are formed in the stepped portion 27. The finger contact portions 28 and 29 are provided along the left and right side edge portions of the housing end surface 18 and are formed so as to protrude from the side surface portion 30 of the female housing 13.

  The female connector 11 is provided with an electric wire holding member 31 for holding the bundled electric wires 14 as will be described later. The electric wire holding member 31 is located on the housing end surface 18 side and is formed to protrude from the side surface portion 30 in a direction intersecting with the female terminal accommodating portion 20. In detail, the electric wire holding member 31 is connected to the housing end surface 18 and the side surface portion 30. The base end portion 32 rises obliquely backward from the base end portion 32 and the routing portion 33 extends from the base end portion 32 in a direction substantially orthogonal to the female terminal accommodating portion 20. The routing portion 33 is formed with a routing surface 34 for routing the electric wire 14.

  FIG. 3 shows a state in which the female terminal 15 is accommodated in the female terminal accommodating portion 20 of the female connector 11. The female terminal 15 includes a plate-like member 35 that extends in the longitudinal direction and on which the terminal portion of the electric wire 14 is placed, a first crimping portion 36 that crimps the covering portion of the electric wire 14, and a terminal of the electric wire 14. And a contact portion 39 that contacts the mating terminal (male terminal). The first crimping part 36 and the second crimping part 38 are each formed by a pair of crimping pieces extending from both side edges of the plate-like member 35 in the width direction. The contact portion 39 is provided at the longitudinal end portion of the plate-like member 35, and a pair of contact pieces extending from both side edges in the width direction of the plate-like member 35 are bent and the tips are overlapped to form a square tube It is formed in a shape. A space into which the male terminal is inserted is formed inside the contact portion 39, and the inserted male terminal is pressed by a spring mechanism, so that electrical connection between the terminals is possible.

  The female terminal accommodating portion 20 is formed inside the female sub-connector 19 and is a rectangular parallelepiped space that is open at both ends in the front-rear direction. The female terminal housing portion 20 is provided with a position regulating wall (not shown) that restricts further insertion when the tip of the female terminal 15 comes into contact when the female terminal 15 is inserted to a proper position. Further, the female terminal accommodating portion 20 extends into this space and engages with the contact portion 39 of the inserted female terminal 15 to prevent the female terminal 15 from coming out of the female terminal accommodating portion 20. 40 is formed.

  When the female terminal 15 is inserted into the female terminal accommodating portion 20 formed in this way, the female terminal 15 is a surface on which the electric wire 14 of the plate-like member 35 is placed (first crimping portion 36, second crimping portion). 37 and the surface on which the contact portion 39 is located) are inserted so as to face the surface 41 of the female terminal housing portion 20 that extends the lance 40. The female terminal 15 is inserted while being elastically deformed by pressing a lance 40 that extends into the insertion path of the female terminal 15, and when the contact portion 39 gets over the lance 40, the lance 40 that is elastically restored is the rear end of the contact portion 39. Is engaged. Accordingly, the position of the female terminal 15 in the front-rear direction is restricted, and the back surface of the plate-like member 35 (the surface on the back side of the surface on which the electric wire 14 is placed) is in contact with the inner wall surface 42 of the female terminal accommodating portion 20. It becomes a state.

  In this embodiment, all the inner wall surfaces 42 of each female terminal accommodating part 20 are located in the electric wire holding member 31 side (arrow of FIG. 3). In other words, in the female terminals 15 accommodated in the respective female terminal accommodating portions 20, the electric wires 14 are arranged on the side opposite to the electric wire holding member 31 with respect to the plate member 35. For example, referring to the example of FIG. 2, each female terminal accommodating portion 20 has a surface 41 formed on the upper side and an inner wall surface 42 formed on the lower side.

  Next, with reference to FIGS. 4 and 5, a procedure for arranging and fixing the electric wire 14 to the electric wire holding member 31 will be described. As shown in FIG. 4, the plurality of electric wires 14 extracted from each open end 26 are bent downward where the electric wire holding member 31 is positioned. As shown in FIG. 4A, these electric wires 14 are wound and fixed by a binding tool 43 such as an adhesive tape, and are bundled into one electric wire bundle 44. Subsequently, as illustrated in FIG. 4B, the wire bundle 44 is routed on the routing surface 34 of the wire holding member 31 that extends downward from the housing end surface 18. As shown in FIG. 5, the wire bundle 44 routed on the routing surface 34 is wound around the wire holding member 31 and fixed by a binding tool 45 such as an adhesive tape. Thereby, even if a tensile stress of the electric wire 14 is generated in each arrow direction in FIG. 5, the electric wire holding member 31 is elastically deformed so that the tension applied to the electric wire 14 is relaxed and applied to the crimping portion with the female terminal 15. Stress can be weakened.

  On the other hand, the female terminal 15 accommodated in the female terminal accommodating portion 20 is held in a state where the plate-like member 35 is in contact with the inner wall surface 42 of the female terminal accommodating portion 20 provided on the electric wire holding member 31 side in the longitudinal direction. . Therefore, for example, as shown by the dotted line in FIG. 5, even if the external force when the electric wire 14 is greatly curved, that is, the external force that presses the female terminal 15 against the electric wire holding member 31 side acts on the female terminal 15, Since the inner wall surface 42 located on the back side of the wire 35 is provided on the electric wire holding member 31 side, the external force applied to the female terminal 15 can be absorbed by the inner wall surface 42.

  Thus, in this embodiment, when the external force of the electric wire 14 acts on the female terminal 15, the female terminal 15 can be pressed against the inner wall surface 42 and can be held, so that the female terminal 15 can be prevented from tilting or rattling. Thus, the female terminal 15 can be stably held. Further, even if such external force due to the bending of the electric wire 14 acts on the crimping portion of the electric wire 14 (the crimping portion of the electric wire 14 and the first crimping portion 36 and the crimping portion of the conductor 37 and the second crimping portion 38). These electric wires 14 receive an external force not in a direction away from the plate-like member 35 but in a direction in which the plate-like member 35 is pressed, so that it is possible to suppress a load from being concentrated on a part of the electric wires 14. Therefore, since the stable contact state between the male terminal and the female terminal 15 can be maintained, the electrical reliability of the connector can be enhanced.

  Further, as shown in FIG. 5, the female connector 11 of the present embodiment has a proximal end portion 32 in which the wire holding member 31 rises obliquely from the side surface portion 30, and thus the routing surface 34 of the wire holding member 31. Can be easily provided at a desired distance from the open end 26 of the housing end surface 18. In the present embodiment, for example, the distance L1 in the front-rear direction between the housing end surface 18 and the routing surface 34 of the electric wire holding member 31 and the electric wire so that the external force applied to the female terminal 15 by bending the electric wire 14 is less than the setting. The distance L2 in the vertical direction between the inner wall surface 42 of the opening end 26 closest to the holding member 31 and the base portion 46 (boundary between the base end portion 32 and the routing portion 33) of the routing portion 33 of the wire holding member 31. Set at least one of them.

  According to this, since the excessive bending of the electric wire 14 can be prevented and the external force applied to the female terminal 15 by bending the electric wire 14 can be set below the set value, the female terminal 15 can be held more stably by the female terminal accommodating portion 20. And concentration of load on the electric wire 14 can be suppressed.

  Next, the configuration of the wire holding member 31 of the connector 11 will be described in detail. As shown in an enlarged view in FIG. 2, the electric wire holding member 31 has a semicircular arc cross section that is perpendicular to the longitudinal direction of the routing portion 33, and the longitudinal ends thereof are formed from both side edges in the width direction. Locking protrusions 47 that protrude from each other are provided. The locking projection 47 is formed to be continuous with the wiring portion 33 in a semicircular shape. The electric wire holding member 31 is covered with a resin corrugated tube, which will be described later, together with the electric wire bundle 44 arranged in the longitudinal direction.

  FIG. 6 shows a cross section of the electric wire holding member 31 to which the corrugated tube 48 is attached. The corrugated tube 48 is formed in a cylindrical shape, and protects the electric wire bundle 44 from an external force or the like while ensuring the degree of freedom for arranging the electric wire bundle 44. The corrugated tube 48 is formed in a bellows shape with slits (not shown) extending between both ends of the cylindrical shape, and can be freely deformed. The entire length of the corrugated tube 48 is set longer than the dimension in the longitudinal direction of the routing portion 33 of the electric wire holding member 31. On the inner peripheral surface of the corrugated tube 48, annular crests 49 projecting inward and annular troughs 50 projecting outward are continuously formed alternately in the axial direction.

  As shown in an enlarged view in FIG. 6, the locking protrusion 47 of the electric wire holding member 31 is formed so as to be able to engage with the valley 50 of the corrugated tube 48 when the corrugated tube 48 is covered. Each locking projection 47 is formed with a chamfered slope 51 that narrows the protruding tip side of the locking projection 47 on the side surface (lower side surface) located on the opposite side of the female housing 13. In addition, the slope 51 is not provided on the side surface (upper side surface) on the female housing 13 side in each locking projection 47.

  Next, a procedure for attaching the corrugated tube 48 will be described. As shown in FIG. 7A, in a state where the wire bundle 44 is placed on the routing surface 34 of the wire holding member 31, the slit of the corrugated tube 48 is forcibly opened and the wire bundle 44 is opened from the opened slit. Insert into corrugated tube 48. Subsequently, the corrugated tube 48 is moved to the electric wire holding member 31 side, and the electric wire holding member 31 and the electric wire bundle 44 are covered with the corrugated tube 48. In this way, the corrugated tube 48 surrounding the electric wire holding member 31 in the longitudinal direction is engaged with the electric wire holding member 31 by engaging the locking protrusion 47 with the valley portion 50 on the inner peripheral surface (FIG. 6). . Then, as shown in FIG.7 (b), the outer peripheral surface of the corrugated tube 48 is wound with the binding tools 52, such as an adhesive tape. Thereby, the corrugated tube 48 is fixed to the electric wire holding member 31 in a state where the electric wire holding member 31 and the electric wire bundle 44 are accommodated.

  According to the present embodiment, since the corrugated tube 48 can be held by engaging the locking protrusion 47 with the valley 50 on the inner peripheral surface of the corrugated tube 48, when the binding tool 52 is wound around the corrugated tube 48. In addition, the corrugated tube 48 can be prevented from falling off the electric wire holding member 31, and the working efficiency when the binding tool 52 is wound around the corrugated tube 48 can be enhanced. Moreover, since the electric wire holding member 31 is formed in a semicircular cross-sectional shape and can be brought into contact with the inner peripheral surface of the corrugated tube 48 in the circumferential direction, it is possible to more effectively suppress the corrugated tube 48 from falling off, In addition, it is possible to increase the work efficiency by making it easier to wind the binding tool 52.

  In addition, according to the present embodiment, since the slope portion 51 is formed on the side surface below the locking projection 47, when the electric wire holding member 31 is inserted into the corrugated tube 48, the slope portion 51 is the corrugated tube 48. Makes smooth contact with the inner peripheral surface. Thereby, the wearability of the corrugated tube 48 can be improved and damage to the corrugated tube 48 can be prevented. In addition, since the inclined portion 51 is not formed on the side surface above the locking projection 47, the corrugated tube 48 does not easily come out of the electric wire holding member 31.

  Next, the configuration of the housing end surface 18 of the connector 11 will be described in detail. As shown in FIG. 8, on the periphery of the housing end surface 18, a plurality of step portions, that is, a step portion 27, and finger contact portions 28 and 29 are provided so as to surround a plurality of opening ends 26a formed on a flat surface. Projectingly. These step portions are conventionally provided on the housing end surface 18, the step portion 27 is a plate-like protrusion provided in accordance with the entire length of the female terminal 15, and the finger contact portions 28 and 29 are female connectors. This is a protrusion for holding the female connector 11 when the 11 is attached or detached. These step portions are formed integrally with the female housing 13 together with the housing end surface 18.

  The step portion 27 is formed so that the cross section protrudes in a substantially trapezoidal shape, and a plurality of opening ends 26b are formed. In FIG. 8, an inclined surface 53 that is inclined at an acute angle with respect to the vertical direction is formed on the inward side surface of the step portion 27 (the side surface facing the plurality of opening ends 26a). The inclined surface 53 is provided across both ends of the side surface located above the stepped portion 27 when the stepped portion 27 is positioned below the plurality of opening ends 26a, and is inclined downward toward one end. Is done.

  The finger contact portion 28 is formed so as to protrude in a substantially triangular shape having a narrow cross section, and is positioned below the plurality of opening ends 26a. On the side surface (the side surface facing the plurality of opening ends 26 a) located above the finger contact portion 28, two inclined surfaces 54 and 55 that are inclined downward toward both ends thereof are formed.

  Further, the finger contact portion 29 is formed so as to protrude in a substantially triangular shape having a narrow cross section, and is positioned above the plurality of opening ends 26a. Two inclined surfaces 56 and 57 that are inclined upward toward both ends thereof are formed on the side surface (the side surface facing the plurality of opening ends 26a) located below the finger contact portion 28.

  When these step portions are positioned below the plurality of opening ends 26a, the side surfaces positioned above the step portions are inclined toward the at least one of both ends (first inclined surfaces). have. Further, the housing end surface 18 has a flat surface surrounded by these step portions. For this reason, when a water droplet adheres to the housing end surface 18 due to condensation or the like, the water droplet flows down along the housing end surface 18 by its own weight. And the water droplet which flowed down to the inclined surface of the step part located below is drained from one end side along the inclined surface of the step part. According to this, water adhering to the housing end surface 18 can be removed naturally, and it is possible to prevent water from accumulating on the housing end surface 18. Can be surely prevented.

  Further, the following structure may be employed together with the stepped portion or instead of the stepped portion. As shown in FIG. 8, the electric wire holding member 31 has an inclined surface 58 (second surface) on the side surface located above the base end portion 32 rising from the housing end surface 18 when the longitudinal direction of the routing portion 33 is oriented in the horizontal direction. Are formed). The inclined surface 58 is formed to be inclined downward toward one end thereof. The electric wire holding member 31 is also formed with a similar inclined surface 58 on the side surface located below the base end portion 32.

  According to this, for example, when the electric wire holding member 31 is arranged in the horizontal direction, water droplets adhering to the housing end surface 18 flow down to the inclined surface 58 due to their own weight, and are drained from one end side along the inclined surface 58. The Even if comprised in this way, since it can prevent that water accumulates on the housing end surface 18 similarly to said step part, the short circuit of the female terminals 15 can be prevented.

  FIG. 9 shows the flow of water on the housing end surface 18 on which the inclined surfaces 53 to 58 are formed. (A) and (b) of a figure have the relationship rotated 180 degreeC mutually, and the arrow shows the flow direction of water. Even when the housing end surface 18 is inverted in the vertical direction as described above, the water that has flowed down the housing end surface 18 flows along the inclined surfaces 53 to 58, and outside the housing end surface 18 (the side surface portion 30 and the like). Drained.

  As shown in FIG. 9, in addition to the inclined surface 53, the stepped portion 27 may be formed with inclined surfaces 59 and 60 having acute angles with respect to the horizontal direction on the side surfaces respectively connected to both ends of the inclined surface 53. Good.

  As mentioned above, although embodiment of this invention has been explained in full detail with drawing, said embodiment is only an illustration of this invention and this invention is not limited only to the structure of said embodiment. . Needless to say, even if there is a design change within a range not departing from the gist of the present invention, it is included in the present invention.

  For example, in the embodiment described above, the example in which the present invention is applied to the female connector 11 has been described, but the same configuration may be applied to the male connector 12.
