JP 2013-187004 A

  The conventional electric wire with a connector is connected to the mating connector by an operator picking the connector with a finger and moving the connector toward the mating connector. For this reason, depending on the position of the mating connector, it may be difficult to pick the connector and connect it to the mating connector. In this case, for example, the connector may be connected to the mating connector by pushing the proximal end side of the connector with a finger. In this case, it is difficult to sense that the connector and the mating connector are normally connected, which may result in poor connection.

  Therefore, an object of the present invention is to provide a connector that can satisfactorily connect to a mating connector.

  A first aspect is a connector that can be connected to a mating connector, and includes a connector housing in which a plurality of terminal accommodating chambers for accommodating terminal fittings attached to ends of insulated wires are formed, and an outer periphery of the connector housing And an upstanding portion having a thickness smaller than the width of the connector housing.

  A 2nd aspect is a connector of a 1st aspect, Comprising: The said standing part is extended from the front end side connected to the said other party connector of the said connector to the base end side opposite to it.

  A third aspect is the connector according to the first aspect or the second aspect, wherein the connector housing includes a connector housing portion in which the terminal accommodating chamber is formed, and insulation extending from the terminal accommodating chamber in the connector housing portion. A cover portion that covers an extension portion of the electric wire, and the upright portion is provided on the cover portion.

  A 4th aspect is an electric wire with a connector, Comprising: Any one connector of the 1st aspect to the 3rd aspect, and the electric wire with a terminal which has the said terminal metal fitting accommodated in the said terminal accommodating chamber.

  According to the connector of the first aspect, the connector housing can be connected to the mating connector with the upright portion interposed therebetween. Therefore, the connector can be easily connected to the mating connector arranged in a narrow space. Further, it can be detected through the upright portion that the connector is connected to the mating connector. For this reason, connector connection can be performed satisfactorily.

  According to the connector of the second aspect, since the upright portion extends in the moving direction of the connector, the connector can be connected to the mating connector by moving the connector in the extending direction with the upright portion sandwiched therebetween.

  Further, according to the connector of the third aspect, since the standing part is provided in the cover part away from the connector housing, even when the space around the connector housing is narrow, by grasping the standing part of the cover part The connector housing can be connected to the mating connector well.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the component described in this embodiment is an illustration to the last, and is not a thing of the meaning which limits the scope of the present invention only to them. In the drawings, the size and number of each part may be exaggerated or simplified as necessary for easy understanding.

<1. First Embodiment>
FIG.1 and FIG.2 is a schematic perspective view of the electric wire 10 with a connector of 1st Embodiment. FIG. 1 shows a state before the connector 20 of the electric wire with connector 10 is connected to the mating connector 90, and FIG. 2 shows a state where the connector 20 of the electric wire with connector 10 is connected to the mating connector 90.

<Electric wire with connector>
The electric wire with connector 10 includes a connector 20, an insulated electric wire 30, and a terminal fitting 40. The connector-attached electric wire 10 is used to electrically connect various electric devices mounted on a vehicle or the like in a state where the electric wire 10 with a connector is arranged at a location to be arranged such as a vehicle such as an automobile. The electric wire with connector 10 is particularly suitable for use in a space with little space such as in an engine room, but the application is not limited thereto.

<Connector>
The connector 20 is a member molded with an insulating material such as resin. Here, the connector 20 includes a connector housing 22 formed in a substantially rectangular parallelepiped shape, and an upright portion 24 formed in a plate shape standing on the upper surface of the connector housing 22.

<Connector housing>
The connector housing 22 has a plurality of terminal accommodating chambers (also referred to as “cavities”) 220 penetrating from the distal end side (side connected to the mating connector 90) to the proximal end side (opposite the distal end). (Eight in the illustrated example) are formed. The terminal accommodating chamber 220 is a space that accommodates the terminal fitting 40 attached to the distal end portion of the insulated wire 30 therein.

  As shown in FIG. 1, the connector 20 has a side (tip side) to which the connector housing 22 is connected facing the mating connector 90, and a direction in which the connector housing 22 approaches the mating connector 90 (connection direction). The connector housing 22 is connected to the mating connector 90 by moving to D1).

<Standing part>
The standing portion 24 is a portion formed so as to stand up from the outer peripheral surface of the connector housing 22. In this example, the standing part 24 is formed in a plate shape. “Plate-like” refers to a shape having a pair of main surfaces that are wider than the side surfaces and face each other. Here, the standing part 24 is formed in a rectangular parallelepiped shape, and a pair of opposing main surfaces 24S and 24S (widest surface) are flat surfaces and are congruent rectangles. In addition, it is not essential that a pair of main surface is a plane. For example, a concave surface may be used. It is not essential that the pair of main surfaces 24S, 24S in the standing portion 24 is congruent.

  The standing portion 24 extends from the distal end side (side connected to the mating connector 90) of the connector housing 22 to the base end side (side from which the insulated wire 30 extends). In this example, the upright portion 24 extends in parallel to the connection direction D1, and the pair of main surfaces 24S and 24S are parallel to the connection direction D1. However, it is not essential that the standing portion 24 extends in parallel with the connection direction D1. That is, it is only necessary to extend in a direction (combining direction) in which the connection direction D1 and the direction orthogonal to the connecting direction D1 are combined.

  The thickness Th <b> 1 of the upright portion 24 is smaller than the width W <b> 1 of the connector housing 22. In other words, when the upright portion 24 is projected onto the connector housing 22, the projected image of the upright portion 24 is smaller than the connector housing 22.

  Even when it is difficult to grasp the connector housing 22 from both sides when the mating connector 90 is provided in a narrow space and other members are arranged on both sides of the connector housing 22, It becomes possible to pick up the standing part 24. Therefore, it becomes easy to connect the connector housing 22 to the mating connector 90.

  Although not shown, the connector housing 22 and the mating connector 90 have a locking structure. The locking structure is composed of, for example, a locking claw and a locking part that is hooked by the locking claw. When the locking claw is caught by the locking portion, the connector housing 22 and the mating connector 90 are connected in a state of being prevented from coming off from each other. When the locking claw is caught by the locking portion, the operator can detect it through the standing portion 24. Therefore, the connector housing 22 and the mating connector 90 can be connected well.

<Insulated wire>
The insulated wire 30 includes a core wire (not shown) and an insulating coating 32 surrounding the core wire. The core wire of the insulated wire 30 is a conductive member, and is specifically formed of copper, copper alloy, aluminum, or aluminum alloy. The insulation coating 32 of the insulated wire 30 is formed of a non-conductive flexible synthetic resin material such as vinyl chloride (PVC), polyethylene (PE), or cross-linked polyethylene (XLPE).

  The tip of the insulated wire 30 is processed in a state in which the insulation coating 32 has been peeled off from around the core wire of a certain length in advance, that is, a state where the core wire of a certain length extends from the insulation coating 32. . A core wire extending from the insulating coating 32 is connected to the terminal fitting 40.

<Terminal fitting>
The terminal fitting 40 is mechanically and electrically connected to the core wire of the insulated wire 30. The connection between the terminal fitting 40 and the core wire of the insulated wire 30 is realized by crimping, ultrasonic welding, resistance welding, or soldering.

  The terminal fitting 40 is made of a copper alloy member such as copper or brass, or a tin alloy in which tin (Sn) plating or tin (Ag), copper (Cu), bismuth (Bi) or the like is added to these members. The conductive member is plated.

  The distal end portion of the terminal fitting 40 is a contact portion that is electrically connected to the counterpart terminal. In this example, the contact portion has a cylindrical female terminal shape, but may have a tab-shaped or pin-shaped male terminal shape.

  Each of the terminal fittings 40 attached to the end portions of the plurality of insulated wires 30 is inserted into each of the terminal accommodating chambers 220 of the connector housing 22 from the proximal end side, and is locked and fixed inside each of the terminal accommodating chambers 220. In this state, each insulated wire 30 extends to the proximal end side of the connector housing 22.

  The plurality of insulated wires 30 are bound by a binding tool 50. In this example, the binding tool 50 is an adhesive tape that is spirally wound around the plurality of insulated wires 30, but may be a binding band.

<Effect>
According to the connector 20, the pair of main surfaces 24 </ b> S of the standing portion 24 can be picked from both sides by an operator, for example, with fingers. Therefore, even if the mating connector 90 is arranged in a narrow space in the vehicle, the connector 20 can be easily connected by grasping the upright portion 24.

  The connector housing 22 can be connected to the mating connector 90 by grasping the upright portion 24, so that it can be sensed that the connection state has been reached. Thereby, the connection of the connector 20 to the mating connector 90 can be performed satisfactorily.

<2. Second Embodiment>
Next, a second embodiment will be described. In the following description, elements having the same functions as the elements already described may be denoted by the same reference numerals or symbols added with alphabetic characters, and detailed description may be omitted.

  FIG. 3 is a schematic plan view of the connector-attached electric wire 10a of the second embodiment. 4 and 5 are schematic side views of the connector-attached electric wire 10a of the second embodiment. FIG. 3 is a view in which the cover portion 26 of the connector 20a is partially cut away. 4 is a view of the electric wire with connector 10a as viewed from the side where the through hole 260 of the cover portion 26 is provided, and FIG. 5 is a side opposite to the side where the through hole 260 is provided with the electric wire with connector 10a. It is the figure seen from.

  The electric wire with connector 10a includes a connector 20a. The connector 20a includes a connector housing 22a and a cover portion 26 that can be connected to the base end side of the connector housing 22a. A standing portion 24 is provided on a part of the outer peripheral surface of the cover portion 26.

  The cover portion 26 can be attached to and detached from the proximal end portion of the connector housing 22a. Specifically, a portion of the cover portion 26 that is attached to the proximal end side of the connector housing 22a forms a substantially rectangular frame portion. The cover portion 26 is attached to the connector housing 22a by press-fitting the frame portion to the outside of the protruding piece 222 protruding from the inside of the connector housing 22a.

  A through hole 260 is formed in the cover portion 26. The plurality of insulated wires 30 extending from the connector housing 22 a extend from the inside of the cover portion 26 to the outside of the cover portion 26 through the through holes 260. The through-hole 260 is provided in the side wall which forms one side of the substantially rectangular frame part with which the cover part 26 is mounted | worn with the base end side of the connector housing 22a. The plurality of insulated wires 30 are bent in the cover portion 26 and led out to the outside of the cover portion 26 through the through holes 260. That is, the cover part 26 is a member that covers the periphery of the bent portions of the plurality of insulated wires 30.

<Effect>
Also in the electric wire 10a with a connector, the standing part 24 is provided in the cover part 26 of the connector 20a. For this reason, the operator can pick up the standing portion 24 and connect the connector 20a to the mating connector 90. Therefore, even if the mating connector 90 is arranged in a narrow space, the connector 20a can be easily connected to the mating connector 90.

  A standing portion 24 is formed on the cover portion 26. For this reason, the connector housing 22a can be held via the upright portion 24 at a position away from the mating connector 90, and the connector housing 22a can be moved toward the mating connector 90. Therefore, even when the space around the mating connector 90 is narrow, the connector 20a can be satisfactorily connected to the mating connector 90.

  In addition, it is not essential that the standing part 24 is provided in the cover part 26. For example, the standing part 24 may be provided in the connector housing 22a.

<3. Third Embodiment>
FIG. 6 is a schematic perspective view of the connector-attached electric wire 10b of the third embodiment. The connector-attached electric wire 10b has substantially the same configuration as the connector-attached electric wire 10, but the upright portion 24 extends in a direction orthogonal to the connection direction D1. When connecting the connector-attached electric wire 10b to the mating connector 90, the operator pushes the connector housing 22 in the connection direction D1 by pushing the back surface of the standing portion 24 (the main surface 24S facing the base end side of the connector housing 22) with a finger. Can be moved to. Thus, the connector-attached electric wire 10b can be satisfactorily connected to the mating connector 90. When the connector-attached electric wire 10b is removed from the mating connector 90, the operator pushes the connector housing 22 against the mating connector by pressing the front surface of the standing portion 24 (the main surface 24S facing the tip side of the connector housing 22) with a finger. 90 can be removed.

  Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention. The configurations described in the above embodiments and modifications can be appropriately combined or omitted as long as they do not contradict each other.
