Abstract

PURPOSE: To heighten the mounting workability of a clamp to a shielded wire, and prevent a contact fault between a braid portion and a shielding sleeve. CONSTITUTION: A shielded wire W is passed through a through hole 46, shielding layer Wb is positioned between both pressing clamp portions 42, 42, and the same is mounted in the shielding sleeve 30 so that protrusion pieces 44, 44 are engaged with a guide slope 32. Thereby, both pressing clamp portions 42, 42 sandwich the shielding layer Wb elastically so that the shielding layer Wb and the shielding sleeve 30 are connected via a clamp 40 so as to be electrically conductive. Since such labor as fitting the clamp 40 tightly to the shielded wire W or folding back the shielding layer Wb is not required, fitting workability is high. Since the clamp 40 touches the shielding layer Wb and the shielding sleeve 30 elastically, no chance of any contact fault between the shielding layer Wb and the shielding sleeve 30 is allowed.

On the other hand, the shielded electric wire W has an inner coating W
Peel off c to crimp male terminal metal fitting We onto exposed core wire Wd,
It is fixed by means such as soldering and the outer coating W
A is peeled off to expose the shield layer Wb, and a tape Wf is wound around the end of the shield layer Wb so that the shield layer Wb does not come apart. Furthermore, the outer coating W
A waterproof rubber stopper Wg and a retainer Wh for retaining the rubber stopper Wg are fitted in a.

The shielded electric wire W is inserted into the through hole 46 from the rear of the clamp 40 so that the end surface of the outer covering portion Wa abuts against the rear end surface of the holder 45. As a result, the male terminal metal fitting We largely projects toward the front of the clamp 40, and the shield layer Wb projects forward from the through hole 46 and is located between the clamping portions 42, 42.
When inserting the shielded electric wire W, the through hole 46 has a larger diameter than the shield layer Wb, and both the pinching portions 42, 4 are inserted.
Since the wire 2 is located outside the through hole 46, the shielded wire W does not interfere with the edge of the through hole 46 and the pinching portions 42, 42, and the insertion work can be performed smoothly.

Then, the shield wire W and the clamp 4
0 is released by the protruding pieces 44, 44 of the clamp 40.
The outer covering portion Wa of the shielded electric wire W is grasped and pushed in the direction corresponding to the above, and is inserted into the cavity 24. As the insertion of the shielded wire W proceeds, the pair of protruding pieces 44, 44

In this state, since the protruding piece 44 reaches the parallel holding portion 33 at the inner end of the guide slope 32, the elastic restoring force of the clamp body 41 causes the clamp 40 to move backward with respect to the shielded wire W. There is no danger of slipping.

As described above, in this embodiment, the clamp 4
Since the shield layer Wb only needs to be arranged between the pair of pinching portions 42, 42 when the 0 is assembled to the shielded wire W, the clamp 40 can be closely fitted to the shielded wire W or the shield layer Wb can be fitted to the shielded wire W as in the conventional case. This eliminates the troublesome work of folding back Wb and is excellent in workability. Moreover,
The clamp 40 has a shield layer Wb due to its elastic restoring force.
And the shield cylinder 30 are elastically pressed against each other, a high contact pressure is ensured at these contact portions, and a poor contact between the shield layer Wb and the shield cylinder 30. Will not occur.

In the above operation, before the shielded electric wire W is attached to the housing 21, the shield tube 30 is previously attached.
Although the assembly is carried out by the procedure in which the is mounted on the housing 21, the assembly can be carried out by the following procedure.

First, the shield wire W is penetrated through the through hole 46 of the clamp 40, and the shield wire W is attached to the shield tube 30 before being attached to the housing 21. Also at this time, the protruding piece 4
When the guide slopes 4 and 44 are engaged with the guide slope 32, both clamping portions 4
2, 42 elastically sandwich the shield layer Wb, and the elastic force of the clamp 40 integrates the shield wire W, the clamp 40, and the shield tube 30. The integrated shield wire W, the clamp 40, and the shield cylinder 30 are provided with the mounting groove 31 of the shield cylinder 30 corresponding to the connecting portion 26 of the housing 21 and the protruding piece 44,
It suffices to position 44 in the direction corresponding to the escape groove 32 and insert it into the housing 21.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. The shielded connector of the present embodiment is the one in which the structure of the clamp in the above-described first embodiment is replaced with the structure of the guide slope of the shield tube. Since other configurations are the same as those in the first embodiment, the same reference numerals are given to the same configurations, and the structure,
The description of the action and effect is omitted.

The clamp 50 is the same holder 4 as in the first embodiment.

They cross and extend diagonally opposite to each other.

On the other hand, the shield cylinder 60 is formed with two guide slopes 62a, 62b having different depth dimensions by cutting forward from the rear end edge.
Of the guide slopes 62a and 62b, the longer one of the guide slopes 62a has a protruding piece 54 located on the front side.
In addition to the engagement of a, the projecting piece 54b located on the rear side is engaged with the guide slope 62b having the shorter depth.

When assembling the shielded wire W to the clamp 50, the protrusions 54a and 54b are pinched with fingers to narrow the gap between them, so that the pair of pinching portions 52a and 52b are widened against the elasticity. As a result, both clamping portions 52a,
The interval between 52b is larger than the outer diameter of the shield layer Wb. Then, the shield wire W is inserted through the through-hole 46 so that the shield layer Wb is located between the two pinching portions 52a and 52b.
, And then release the fingers from the protruding pieces 54a and 54b. Then, due to the elastic restoring force of the clamp body 51,
The two clamping portions 52, 52 are displaced so as to narrow the gap, and the shield layer Wb is elastically clamped, whereby the shield wire W and the clamp 50 are integrated and temporarily assembled.

When the shield wire W and the clamp 50, which are temporarily assembled and integrated as described above, are assembled to the shield tube 60, the pair of projecting pieces 54a and 54b engage with the corresponding guide slopes 62a and 62b. The projecting pieces 54a and 54b are elastically displaced so as to be separated from each other, and the contact pressure between the pair of pressing portions 52 and 52 on the shield layer Wb increases accordingly. When the projecting pieces 54a, 54b reach the holding portions 63a, 63b at the inner ends of the guide slopes 62a, 62b, the projecting pieces 54a, 54b
The removal of 54b from the guide slopes 32a, 32b is prevented, and thus the shielded electric wire W, the clamp 50, and the shield tube 60 are integrally assembled.

In this embodiment, as in the first embodiment, the workability of assembling is excellent and the contact failure is prevented. Further, when the shield wire W and the clamp 50 are assembled, the pinching portions 52a and 52b are shielded by the shield layer W.
Since the shield wire W and the clamp 50 are integrated by elastically sandwiching b, it is easy to handle and to assemble the shield tube 60 before the assembly to the shield tube 60. There are advantages.

Moreover, the electric wire W is connected to the through hole 5 of the clamp 50.
It is possible to widen the space between the pressing portions 52a and 52b by a simple operation of pinching the projecting pieces 54a and 54b with fingers when inserting them in 2, so that the temporary assembly is possible as described above. Clamping portions 52a, 52
Although b is elastically sandwiching the shield layer Wb, the workability of the insertion work is excellent.

It may be configured so as to be in contact with the shield layer Wb while being elastically sandwiched. By doing so, the clamp 40 is held in a state of being integrated with the shielded electric wire W as in the second embodiment, so that the handling before the attachment to the shield tube 30 is facilitated. Further, in this case, the holder 40 may not be used, and only the clamp body 41 may be assembled to the shielded wire W.

(2) In the second embodiment, the clamp body 51 is elastically sandwiched by the shield layer Wb so as to be integrated with the shielded electric wire W. Therefore, the holder 45 is used. Instead, only the clamp body 51 may be assembled to the shielded wire W.
