Description

  The present invention relates to a connector, and more particularly to a connector for holding a contact connected to a cable and a reduction in the height thereof.

  Conventionally, as this type of connector, a connector having the structure shown in FIGS. 9 and 10 has been proposed (see Patent Document 1). FIG. 9 is a perspective view of an example of a conventional connector, and FIG. 10 is a cross-sectional view of the connector of FIG. Referring to FIGS. 9 and 10, the connector 102 according to the prior art includes a cable support member 75 of the housing main body 73 that holds the cable 50, and a cable pressing member 74 that is rotatably provided on the housing main body 73 by a hinge 77. It has a structure with a cable in between. Then, the length m from the front end portion 73a of the housing main body 73 to the lower surface end portion 74a in contact with the cable 50 of the cable pressing member 74 is defined as the upper surface end portion 75a in contact with the cable 50 of the cable support member 75 from the front end portion 73a of the housing main body 73. The lower end 74a and the upper end 75a are not located on the same vertical line.

  FIG. 11 shows an example of a contact of a conventional connector. Referring to FIG. 11, the contact 60 includes a connection portion 62, a contact portion 61 provided at one end, a locking portion 65 protruding from the main body to be held in the housing, and a gripping portion for holding the cable 50. 63. The conductor portion of the cable 50 is connected to the connection portion 62 by crimping.

  In such a conventional contact, the gripping portion 63 of the contact 60 is in the same direction as the contact portion 61.

  As a method for holding the contact, there is a locking method such as lance, press-fitting, and sandwiching between two insulators.

  However, the connection part 62 of the contact 60 is on the same straight line as the contact part 61. In the case of an angle type connector, even if the cable is bent, the back H ′ is increased.

  Further, in the case of an angle connector in which the direction in which the cable and the contact are fitted intersects, it is necessary to take out the cable 50 in the vertical direction with respect to the contact part 61. There is a problem that it is difficult.

  In addition, when the contact 60 is sandwiched between two insulators, there is a disadvantage that the number of parts increases, such as using a retaining ring to fix and hold the insulator on the outer shell.

  Furthermore, the contact holding method using a lance for locking has a problem that the contact comes off due to the tilting state of the lance.

  As best shown in FIGS. 2 to 5, the insulator 30 includes a first insulator 31 and a second insulator 21. The first insulator 31 and the second insulator 21 are formed to be rotatable around a shaft 41. Here, in FIGS. 2 and 3, the first and second insulators 31 and 21 are in a closed state, that is, in a locked state. Moreover, in FIG.4 and FIG.5, it exists in the open state, ie, the state before the lock | rock, or the lock release.

  The first insulator 31 includes a B-shaped spring portion 33 on both sides of a free end and a lock hole 32 provided at the center thereof.

  The second insulator 21 has a trapezoidal cross section having a flat surface 22a, an inclined surface 22b, and an engagement surface 22c that are fitted in the lock hole 32 of the first insulator 31 in the locked state on both sides on the free end side. A protrusion 22 is provided.

  As best shown in FIG. 7 and FIG. 8, the first insulator 31 includes a pressing portion 36 having a triangular cross section, and a holding portion is provided on the side of the pressing portion 36 facing the second insulator 21. A pressing surface 37 is provided for pressing the contact 10 accommodated in the pressing member 25, and pressing protrusions 34 and 35 are provided at both ends of the pressing surface 37.

  On the other hand, the second insulator 31 includes a contact accommodating portion 25 in which the contact 10 is accommodated. As will be described in detail later, the contact accommodating portion 25 is formed with a contact portion accommodating portion 24 that accommodates the contact portion 1 of the contact 10 and a slope 28 that contacts the connection portion 2 of the contact 10. Further, a locking portion 27 for locking a protruding piece 5 of the contact 10 described later is provided on the wall portion on the shaft 41 side of the contact portion accommodating portion 24.

  When the contact 10 is received, the pressing protrusion 34 of the first insulator 31 holds the protruding piece 5 of the contact 10 in cooperation with the locking portion 34 of the second insulator 21 so as to be fixed and held.

  Referring to FIG. 6, the contact 10 includes a connection part 2, a contact part 1 projecting through the bending part 6 in a direction inclined with respect to the central axis of the connection part 2 at one end of the connection part 2, and a connection Provided at the other end of the part 2 is a gripping part 3 that holds the cable 50, a contact part 1, and a protruding piece 5 provided at a boundary part of the connection part 2. The cable 50 includes an insulation coating portion 51 and a conductor 52.

It becomes. However, the drawing shows the state before crimping.

  Since the connection part 2 provided with the grip part 3 is in the angle direction of the contact part 1, the height H 'can be lowered, that is, the height can be reduced.

  Further, by arranging the crimping portion (connecting portion 2 and gripping portion 3) of the contact 10 in the intersecting direction with respect to the contact portion 1, the height of the connector 101 can be reduced.

  Next, assembly of the connector according to the embodiment of the present invention will be described.

  As shown in FIG. 7, the contact 10 to which the cable 50 is connected is accommodated in the contact accommodating portion 25 as indicated by an arrow 29. At that time, the connection part 2 or the grip part 3 comes into contact with the inclined surface 28, and the protruding piece 5 comes into contact with the locking part 27.

  Next, the first insulator 31 is closed as indicated by the white arrow in FIG.

  The connection part 2 of the contact 10 is set in a crossing direction with respect to the contact part 1. Further, the contact 10 is sandwiched and held by locking the two insulators to the lock portion.

  Then, the contact portion 1 of the contact 10 and the connected cable 50 are held by the insulator 30 in a state bent to an angle.

  Since the contacts 10 are collectively held by the lock of the first and second insulators 31 and 21, it is not necessary to hold the contacts 10 one by one in the insulator, and parts for holding are unnecessary. In addition, the workability of the harness is improved.

  As described above, in the present invention, after the contact 10 is incorporated into the second insulator 21, the first insulator 31 is put on and locked to complete the mounting of the contact 10, so that the workability is good.

Moreover, against the direction to sandwich the contact 10 in the first and second insulators 31, 21, since the cable 50 is drawn out to the angle direction but also pulls the cable 50, the contact 10 is difficult to pull out, the holding force is strengthened .

  Further, since the connection portion 2 provided with the contact portion 1 and the grip portion 3 of the contact 10 is arranged in advance at an angle, a harness of an angle connector is possible without bending the cable (electric wire) 50, and workability is improved. Will improve. Further, since it is not necessary to bend the cable 50 in the harness, a load caused by bending the cable 50 on the crimping portion and the contact 10 is not applied.

  As described above, the contact of the present invention and the connector using the contact can be applied to a connector that holds the contact connected to the cable.
