(See Publication No. 284). In other words, inside the connector housing 1, a plurality of terminal accommodating chambers 4 surrounded by orthogonal partition walls 2, 3, and 3 are formed. A notch 5.5 is formed which opens the terminal accommodating chamber 4 in the vertical direction and exposes the partition walls 3Y!! located on both sides, and the notch 5.5 has rヱ, The terminal fixing member 6.6 is detachably mounted. - The electric wire 7 is made of a core wire 8 made of a conductor and a skin 9 made of an insulator that covers the wire 8, and a wire 10 is attached to the end of the electric wire 7. Terminal 101
It has a linear pressure reservoir 12, and has an iron core/po crimping g112;! i
! A Shizuiko fitting part 13 is extended in the part. In this configuration, nine terminals 10 are crimped onto the ends of the wires 7 and inserted into the terminal accommodating chamber 4P'3, and then the terminal fixing members 6.6 are attached to the notches 5,5. Then, the terminal fixing member 6,
6 is located behind the terminal 10 and the skin crimping portion 11 and engages with the skin crimping portion 11, so that the terminal 10 is temporarily secured.

Problems to be Solved by the Invention However, in such a conventional structure, the terminal 1
The terminal 10 is configured such that the entire terminal 10 including the surface v15 of the skin 9 and the skin crimping part 11 is housed in the terminal accommodating part 4, including the skin crimping part 11'4. The diameter A of the core wire 8 is as shown in .

) Minimum margin clearance in storage chamber 4, thickness E of partition 3
In the case of 9, between both adjacent terminals 10 and 10, P≧
The minimum pitch P between the terminals is A+2CB+C+D)+E, so each terminal housing chamber 4 is also set to have a sufficient volume to satisfy the condition χ regarding the pitch PK.
There is a need. In order to meet the demand for more compact multiplex connectors, the connector housing 1
Even if an attempt is made to downsize the device, the minimum pitch P between the poles becomes the limit for miniaturization, and it is impossible to meet the requirement for downsizing.

The present invention has been made in consideration of such problems with the conventional equipment.By fixing the skin 9 outside the terminal accommodating chamber 4, P≧A+2CC10')1E can be paid. This structure reduces the interpole pitch PY by a width of 2B, thereby making it possible to downsize the connector housing 1 and providing a compact connector structure.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an electric wire consisting of a core wire and a skin that crushes the core wire in a plurality of terminal accommodating chambers formed in a connector housing. fixed to the end of r
In the structure, the terminal Y: V-notch is made in three layers and housed and fixed in the storage chamber, while the
A separate member is provided outside the 1f terminal accommodating portion to firmly hold the DU recording line skin and to be linked to the connector housing.

In the above structure, since the terminal (σ) is crimped to the core wire, the outer skin covering the core wire is not accommodated in each terminal chamber, and only the 73 wire and the terminal are crimped. The volume can be reduced by the thickness of the epidermis (1) to be removed.
- This makes it possible to downsize the connector housing, and also ensures that it is connected to the connector housing by a separate member on the skin surface.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to Figure WK. That is, as shown in FIG. 1, the connector housing 141'L, the upper and lower layers 15.16 and the left and right sides 1117.18
It is formed into a single shape with a ridge.

Inside this connector housing 140, a number a (in this embodiment, (4)
The terminal housing chamber 4 of ＠) is formed and the temperature is lowered.

As shown in FIG. 2, a retaining piece 21 is provided in the terminal accommodating chamber 4 in a diagonal manner. the left and right side walls 17;
A buried portion 22.23 is formed at the end of 18,
A pair of protrusions 24.2 are provided on the outer surface of the buried portion 22.23.
4 is formed 'rLC color. In addition, at the end edge of the horizontal bulkhead 20, there is a bridge section 25.2 extending over the extension section 22.23.
5 are formed in a parallel shape, and on the upper and lower surfaces K of the receiving caps 25, 25, there are curved recesses 2 corresponding to the respective terminal accommodating chambers 4.
6... is formed. On the other hand, the separate member 27 is approximately U-shaped, and the receiver on the connector housing 14 side is formed in a symmetrical shape with respect to the section 25.
．． 28 is provided, and the receiver is part 2B.

28 is also formed with a similar curved recess 29, and engagement holes 30 that can be engaged with the projections 24 and 24 are formed on both sides of the separate member 27. On the other hand, as shown in FIG. 3, one bale 7 is composed of a core wire 8 and a skin 9 covering the core wire 8. A terminal 31 is attached to the end of the wire 7, and the terminal 31 is attached to the core wire 8 (/J) and the 5 total crimp 1 (S12) and the core wire crimp portion 12.
tLfc quasi-terminal fitting part 13 extending to the end of the tLfc? In FIG. 2, numeral 32 is a through hole formed on the back surface of the connector housing 14cv into which a male t''L'fc is inserted.

In this actual example regarding the above r4 bottom, terminal 31 is $3
As shown in the figure, the core wire crimping part IZY core is crimped with 8 degrees of crimp and attached in advance at ℃. When the terminal 31' is inserted into the terminal housing 4, the retaining piece 21 engages with the edge of the semi-terminal fitting 513 and is held firmly as shown in FIG. After that, the separate member 27Y7 is fitted to the side of the extending portion 23, and the retaining hole 30 is engaged with the protrusion 24, so that the separate member 27 is fixed to the connector housing 14 as shown in FIG. At the same time, the skin 9 is sandwiched between the receiving portions 25 and 28 and linked to the connector housing 14.

In such a state, the skin is 91 mm and the terminal accommodation difference is 4 C1.
) Since it is located outside, as shown in Fig. 5, the diameter of the core wire 8 is A2, the thickness of the skin 9 is B, the terminal 31G/J board thickness C1, the terminal 31 C1) the minimum margin in the storage chamber 4. If the partition wall 190) has a thickness E of 9, the pitch P between both terminals 31 and 31 only needs to satisfy the condition P≧person+2(C+D) 10g. Therefore, the pole pitch P k'
L, as shown in the figure, the minimum adjacent X-rays 7, 7Q)
It becomes possible to reduce the size until the skins 9, 9 are brought into close contact with each other, thereby making it possible to reduce the terminal accommodating difference 4U) volume tg. Therefore, as the volume of each terminal accommodation gap 4 is reduced, the connector housing 14 is made smaller, and it becomes possible to meet the requirements for miniaturization of multi-pole connectors.

Is Fig. 6 another embodiment of the present invention? In this embodiment, the separate member 27Y is rotatably attached to the connector housing 14 via a separate member 27Y and a hinge plate 33Y, which is oT-safe. By rotating, the engagement hole 30 engages with the protrusion 24, and when the terminal 31g is fixed to the housing 14, the work can be done more easily and quickly. In the embodiment, the protrusion 24 is formed on the connector housing 14 and the engagement hole 3nf is formed on the separate member 27, but it is also possible to have the opposite configuration.Detailed Description of the Invention As described above, in the present invention, only the terminal ya1' wire is crimped and housed and fixed in the quadruple accommodating chamber P'3, while the outer skin of the wire is fixed to the outside of the selector accommodating chamber and connected to the connector housing. I decided to install the parts.

Therefore, the outer skin for installing the core wire in the terminal housing MP'3 is not accommodated, and v? Terminals crimped only to wires and dt 7J wires are accommodated. Therefore, the thickness of the epidermis,
It is possible to reduce the volume of the terminal housing difference, and to minimize the difference between adjacent t! Q) It is possible to reduce the pitch between the rods until the skin comrades are satisfied. This makes it possible to downsize the CV9 connector housing, meeting the need for compactness in multi-pole connectors, and also reduces the size of the terminals themselves since there is no need to remove the outer skin of the terminals and apply pressure. Moreover, since the outer skin of the T-wire is connected to the connector housing with a separate valve, the wire may be pulled due to external force, and the terminal may be pulled out of the connector housing. This can also be reliably prevented.
