[0054] Figure 4 to Figure 10 A first embodiment of the invention is illustrated. The connector 1A according to this first embodiment is a high voltage female connector type shielded connector connected to an inverter case (not shown). The connector 1A is attached to the inverter by fitting to a terminal block (not shown) provided inside the inverter. It should be noted that, Figure 10 With Figure 9 (longitudinal section view) the corresponding perspective view, and in Figure 10 In , in order to explain the structures of the lock portions 35 to 38 , 52 to 55 in an easy-to-understand manner, the connector housing 3 , the shield case 4 , the protector 5 , and the like are partially cut away.

[0055] like Figure 4 and Figure 5 As shown, the connector 1A includes: a substantially cylindrical connector housing 3 accommodating a pair of left and right terminals 2; a shield 4 arranged on the outer periphery of the connector housing 3; and a protector 5 arranged to cover ...

[0075] Figures 11A to 14C A second embodiment of the invention is illustrated. like Figure 12A , 12B and Figure 13 As shown, the connector 1B of the second embodiment includes a terminal 2 and a connector housing 3 for accommodating the terminal 2 .

[0076] Similar to the first embodiment explained above, the connector housing 3 is provided with terminal accommodating chambers (not shown) and wire lead-out holes (not shown). A part of the wire lead-out hole is formed as a holder accommodating chamber (not shown). Terminals 2 connected to electric wires 21 are housed in the terminal housing chamber. A rubber stopper 33 attached to the electric wire 21 is accommodated in the electric wire drawing hole. A rear holder 32B as an electric wire holder attached to the electric wire 21 is accommodated in the holder accommodating chamber.

[0077] like Figure 13 , Figure 14A , Figure 14B and Figure 14CSpecifically, similarly to the first embodiment described above, th...

Abstract

This connector is provided with: a connector housing (3) having a holder housing chamber (31c); and a rear holder (32A), with an electrical wire (21) inserted into an electrical wire insertion hole (39) thereof, housed within the a holder housing chamber (31c). The outside diameter dimension (D1) of the electrical wire (21) is larger than the inside diameter dimension (D2) of the electrical wire insertion hole (39) of the rear holder (32A), and the outside diameter dimension (D3) of the rear holder (32A) with the electrical wire (21) housed within the electrical wire insertion hole (39) is smaller than the inside diameter dimension (D4) of the holder housing chamber (31c) of the connector housing (3).

Description

technical field [0001] The present invention relates to a connector having a wire holder for holding wires in a connection housing. Background technique [0002] In the past, a connector has been proposed that has a wire holder for holding the wire in the connector housing. figure 1 , Figure 2A and Figure 2B A first conventional example of such a connector is shown. exist figure 1 , Figure 2A and Figure 2B Among them, the connector 100 includes: a connector housing 102 that accommodates the terminals 101 ; and a shield case 102A arranged to surround a part of the outer circumference of the connector housing 102 . The connector housing 102 is provided with a cylindrical portion 103 protruding rearward from the cylindrical portion of the shield case 102A. A rear holder (wire holder) 104 is attached to the rear end of the cylindrical portion 103 . A protrusion 105 extending in the outer diameter direction is provided on the tip outer periphery of the cylindrical por...
