[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 7 and 8, a terminal of a shielded electric wire 1 is peeled so that a conductor 2, an insulator 3, and a shield layer 4 are exposed, and a terminal 6 is attached to the conductor 2. The terminal 6 is housed in a housing 7, the housing 7 is housed in a metal shell 8, the shield layer 4 is caulked by a front barrel 8 a of the metal shell 8, and the insulating sheath 5 is caulked by a rear barrel 8 b. There is a connector mounting structure for the shielded electric wire 1 in which the shell 8 is housed in the cover 9 (see Japanese Utility Model Publication No. 4-55428).

[0003]

However, when the housing 7 is accommodated in the metal shell 8, the terminal 7 is inserted from above while accommodating the terminal 6 in the rectangular cylindrical metal shell 8 in an oblique axial direction. Due to the structure, the assembling workability is poor and it is difficult to automate, and since the housing 7 needs to be formed with the cutout 8c in the metal shell 8 in order to be inserted from above, there is a problem that the high-frequency characteristics deteriorate. Was.

[0004] The present invention has been made to solve the above-mentioned conventional problems, and has as its object to provide a shielded wire connector mounting structure capable of improving the assemblability and high-frequency characteristics.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a terminal attached to a conductor of a terminal of a shielded electric wire is accommodated in a housing, and a metal shell for accommodating the housing has a divided upper surface. After the housing is housed from the upper opening, the upper opening is closed at the upper surface, and the shield layer and the insulating sheath at the end of the shielded electric wire are caulked with the barrel, and then housed in the cover. A connector mounting structure is provided.

According to the present invention, the terminal and the housing are inserted and housed from above by dividing the upper surface of the metal shell and housing the terminal together with the housing from the upper surface opening, and then closing the upper surface opening with the upper surface. become able to.

According to a second aspect of the present invention, a lock portion is formed on both sides of the upper surface opening of the metal shell and both sides of the upper surface portion so as to be engaged when the upper surface portion closes the upper surface opening. , The upper surface does not shift or fall off.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. Note that the same components and operations as those of the prior art are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIGS. 1 to 3 show a male terminal connector mounting structure of the shielded electric wire 1. FIG.

The terminal of the shielded electric wire 1 is peeled off so that the conductor 2, the insulator 3, and the shield layer 4 are exposed, and the male terminal 6A is attached to the conductor 2 by caulking as in the prior art. The male terminal 6A is housed in a rectangular synthetic resin housing 7 so as to penetrate therethrough.

On the other hand, a rectangular cylindrical metal shell 18 is provided,
The metal shell 18 has a bottom portion 18a and both side portions 18a.
Only the upper surface portion 18c is divided from b and 18b, and the entire upper surface opening 18d is closed by the upper surface portion 18c.

The upper surface 18c has two side surfaces 18b,
Both sides 18 respectively fitted to the outer surface of the upper part of 18b
lock projections 18 formed on both side portions 18b when they are fitted to the outer surfaces of the upper portions of both side portions 18b.
Lock holes 18g,... that engage with f,.

According to the above configuration, the male terminal 6A is attached to the conductor 2 of the shielded electric wire 1 by caulking.
Is housed in the housing 7, and the terminal 6A together with the housing 7 is passed through the upper opening 18d from which the upper surface 18c is removed.
Is accommodated in the metal shell 18.

In this state, the upper surface opening 18c
When d is closed, each lock hole 18g of the upper surface portion 18c engages with each lock protrusion 18f of the both side surface portions 18b, and the upper surface portion 1
8c is locked.

Further, the shield layer 4 is caulked by the front barrel 18h of the metal shell 18, and the insulating sheath 5 is caulked by the rear barrel 18i.

Thereafter, the metal shell 18 is housed in the cover 9 as in the prior art.

As described above, the terminal 6A and the housing 7
Can be inserted into the metal shell 18 from above and accommodated.
As compared with the conventional insertion from the axial direction, the assembling workability is improved and automation becomes easier.

Further, since the entire upper surface opening 18d of the metal shell 18 is closed by the upper surface portion 18c, the number of cut-out portions as in the prior art is reduced, so that high-frequency characteristics are improved.

Further, since the upper surface portion 18c can be locked by the side surface portions 18b of the upper surface opening 18d of the metal shell 18,
Since the upper surface portion 18c does not shift or drop off,
The assembling workability when the metal shell 18 is accommodated in the cover 9 is improved.

FIGS. 4 to 6 show a connector mounting structure for the female terminal of the shielded electric wire 1, which is basically the same as the connector mounting structure for the male terminal of FIGS. The female terminal 6 </ b> B is attached by caulking to the housing 2 and housed in the housing 7.

The two side portions 18e, 18e of the upper surface portion 18c of the metal shell 18 are engaged with lock holes 18g,... Formed in the both side surface portions 18b when fitted on the inner surfaces of the upper portions of the both side surface portions 18b, 18b. Lock projection 18f,
... are formed.

Then, the female terminal 6B is caulked and attached to the conductor 2 of the shielded electric wire 1, the female terminal 6B is housed in the housing 7, and then the terminal 6B is housed in the metal shell 18 together with the housing 7 from the upper opening 18d. In this state, when the upper surface opening 18d is closed by the upper surface portion 18c, the lock projections 18f of the upper surface portion 18c are engaged with the lock holes 18g of the both side surface portions 18b, and the upper surface portion 18c is locked.

After the shield layer 4 is caulked by the front barrel 18h of the metal shell 18 and the insulating sheath 5 is caulked by the rear barrel 18i, the metal shell 18
Is stored in the cover 9.

[0024]

As is clear from the above description, in the connector mounting structure of the shielded electric wire according to the present invention, the terminal is housed in the metal shell from the upper opening together with the housing, and then the upper opening is closed at the upper surface. Therefore, the workability of assembling the terminal and the housing is improved, so that the terminal can be easily automated, and the number of cut-out portions on the upper surface of the metal shell is reduced, so that the high-frequency characteristics are also improved.

Further, since the upper surface portion is locked when the upper surface opening of the metal shell is closed, the upper surface portion does not shift or drop off. The assembling workability at the time of accommodation is improved.
