FIG. 1 is a perspective view showing a press-connecting connector according to an embodiment of the present invention, and shows a state in which a trunk wire 11 and a branch wire 12 that are press-connecting wires 10 are press-connected in a casing 20. .

In FIG. 5, a casing 20 includes a housing 30 as a housing base portion shown in FIGS. 2 and 3, and FIG.
As shown in FIG. 5, the housing 30 is composed of a cover 40 as a cover body capable of covering the upper surface and both side surfaces of the housing 30.
Is pulled out from both side surfaces in the longitudinal direction and held. In the present embodiment, four sets of the pressure contact electric wires 10 can be laterally arranged and held, but the number of the pressure contact electric wires 10 to be pressure connected can be appropriately increased or decreased.

The housing 30 supports the four press contact blades 50 in a staggered arrangement. The press contact blade 50 is formed by forming a slit-shaped notch 51 from the end of the flat metal plate in the lateral direction toward the longitudinal axial direction, and the housing 30 is pressed against the upper surface of the flat plate substrate 31. Four pairs of opposing support walls 32 capable of supporting and holding both sides of the blade 50
(32a, 32b, 32c, 32d) are stood in a staggered arrangement. Each support wall pair 32 is formed with support grooves 33, 33 corresponding to the thickness of the press contact blades 50 on the opposite surfaces, and when the flat plate substrate 31 is placed downward, the support contact grooves 50 are formed from above the support groove 33, 33. It can be inserted and supported through the top opening. It should be noted that the mounting table 34 (34a, 34b, 34c, 3) whose upper surface has an arcuate recess so that the pressure contact electric wire can be mounted in front of and behind the opening in each pair of support walls 32.
4d) is formed, and the support walls 32 are arranged in a staggered manner, so that the mounting bases 34 that are adjacent to each other in the lateral direction are also alternately arranged with long ones and short ones.

In this embodiment, the press contact blade 50 is formed by forming the slit-shaped notch 51 on the flat metal plate, but as the press contact blade 50, various conventional press contact blades may be adopted. it can. Further, FIG. 4 shows a pressure contact blade in which both ends of the metal strip are made different in length and folded back in a U shape in the same direction, and notches are formed in the length direction from both ends. The press-connecting electric wires 10 are arranged in two stages vertically while being pressed against the individual press-contact blade portions, and can be accommodated compactly.

On the cover 40 side, the support wall recesses 4 are provided at positions facing the support wall pairs 32 and the mounting table 34.
1 and a mounting table recess 42 are formed, and the support wall pair 32
Due to the formation of the mounting table 34 in the front and rear, these recesses 41, 42 are continuous in the front and rear, and four continuous groove-shaped portions are formed corresponding to the four pairs of support walls 32. Here, the support wall recess 41 can be supported so as not to open to both sides when the support wall pair 32 is inserted, and the mounting table recess 42 is provided when the mounting table 34 is inserted. A through hole for inserting the press-connecting electric wire 10 can be formed between them.

In this embodiment, the pressure contact blades 5 adjacent to each other are used.
It is arranged in a staggered pattern in which 0s are alternately shifted back and forth, but it suffices if the adjacent pressure contact blades are not aligned in the lateral direction.
For example, they can be arranged in three steps such as front, middle, and rear. Support wall pairs 32a at both ends,
Since 32d is obliquely displaced from the pair of inner support walls 32b and 32c, the pair of outermost support walls 32a and 32d are arranged.
There is a vacant portion outside the mounting tables 34a and 34d that are in series with d. Therefore, wedge-shaped lock protrusions 35, 35 are formed on the outer surfaces of the respective mounting tables 34a, 34d, and in the cover 40 from the upper surface to both side surfaces of the mounting tables 34a, 34d, the outer surfaces of the mounting tables 34a, 34d are covered. The facing portions are plate-like arms 43, 43, and claw portions 43a, 43a capable of engaging with the lock projections 35, 35 are formed at the lower ends thereof.

In this embodiment, the mounting tables 34a, 34a, 3

Besides, various configurations can be easily adopted. Next, the operation of this embodiment having the above configuration will be described. In the housing 30, the support groove 33 formed in each support wall pair 32,
The press-connecting blade 50 is press-fitted from above to the 33, and is mounted on the cover 40 so as to extend over the support wall recess 41 and the mounting table recess 42 that communicate with each other in the front and rear.
The trunk line electric wire 11 and the branch line electric wire 12 are stacked and inserted in two stages. Here, the main wire 11 is the recess 4
In many cases, the wires 1 and 42 pass through, but since the branch line electric wire 12 is branched from the main line electric wire 11, it is often led out to only one side. In this case, the branch wire 12 is disposed so as to cross at least the support wall recess 41.

When the above preparations are completed, the housing 30 and the cover 40 are faced to each other and combined. On the cover 40 side, the trunk line electric wire 11 and the branch line electric wire 12 are accommodated in a double stack in the support wall recess 41, and are supported in the support wall recess 32 between the support wall pair 32. Since the pressure contact blade 50 is pushed in, the notch 51 formed in the same pressure contact blade 50 is pushed in while cutting through the coating of both electric wires 11 and 12, and pressure contact is made. The pressure contact state between the pressure contact blade 50 and these electric wires 11 and 12 is shown in FIG. Here, the press-contact blades 50 themselves are wider than the press-connecting electric wires 10, but are arranged in a staggered arrangement, so that the intervals between the press-connecting electric wires 10 are narrowed and the widthwise direction is very compact.

On the other hand, at both ends of the housing 30, the arms 43, 43 of the cover 40 are pushed in so as to cover the outer surfaces of the mounting tables 34a, 34d, and the claws 43a, 43a formed on the inner side of the tips are locked by the locking projections 35, 35. Get over 35 and lock. The arms 43, 43 also utilize the vacant portions caused by the staggered arrangement, which contributes to narrowing the overall width. In the present embodiment, the number of the pressure contact blades 50 is an even number, and the vacant portions at both ends are formed at the target positions. Is improving.

As described above, since the press-contact blades 50 are arranged in a staggered manner and held in the housing 30, and the lock mechanism for the cover 40 and the housing 30 is formed in the vacant portions on both ends generated by the staggered arrangement, the width is narrow as a whole. Can be made into a compact shape.
