Description

[Detailed description of the invention] (Industrial application field) This invention is applicable to the attachment part of a cable clamp, especially a saddle-shaped cable that is made by combining two shells of approximately the same type and is installed in a connector hood or the like. This relates to the structure of the clamp attachment part.

(Prior art) Figure 5 shows the end of one shell 1 of a conventional connector hood, a cable clamp section at the cable outlet, and is a perspective view with the other shell and mounting screws removed. FIG. 6 shows a top view of the saddle-shaped cable clamp 2 attached with the mounting screw 3. As can be seen from the figure, the saddle-shaped cable clamp 2 has a U-shaped portion 21 that holds down an electric wire (not shown), and a tongue piece 23 having mounting holes 22 at both ends thereof is extended. Both mounting holes 22 are provided at positions perpendicular to the direction and symmetrical to each other with respect to the center line of the saddle-shaped cable clamp 2, and the corresponding portions of the shell 1 serve as entrances for the screw holes 11. There is a mounting surface 12.

(Problems that the invention attempts to solve) Recently, the cycle of new and old products has become faster and there has been a trend toward producing a wide variety of products in small quantities, making it difficult to achieve mass production effects. One of the countermeasures is to save on molds by standardizing parts.

Connector hoods and the like are often made of two shells put together, and if the mounting parts of parts such as cable clamps and the fastening parts of the shells are devised, they can be completely hermaphroditic, that is, molded using the same mold. It can be constructed by combining two shells. For the fastening parts of the shells, it is sufficient to provide through holes in the corresponding parts and counterbore the outward facing sides, but there are some conditions for the attachment part of the cable clamp, which will be explained next.

FIG. 7 shows a BB cross section in FIG. 6.

As can be seen from the figure, the mounting surface 12 on which the screw hole 11 is provided is set so that the thickness of the saddle-shaped cable clamp 2 and the height of the head 31 of the mounting screw 3 can be accommodated in between. Each must be moved back by a position. However, although the saddle-shaped cable clamp 2 requires a strong tightening force and the screw hole 11 also requires a suitable effective depth, recent connectors have become thinner and it is not possible to make the screw hole 11 deep. were becoming more common.

(Purpose of the invention) The purpose of the invention is to change the position of the screws for attaching parts such as cable clamps even in thin hermaphroditic shells so that when a pair of identical shells are combined, the screw hole positions do not face each other. and mounting surface 1
To provide a hermaphroditic thin shell having a structure in which the depth of the screw hole can be maximized without causing the screw hole 2 to retreat from the reference plane c.

(Structure of the invention) A preferred embodiment of this invention will be described based on the drawings. FIG. 1 is an exploded perspective view of one of the hermaphroditic thin shells 4, 4' forming the connector hood, a saddle-shaped cable clamp 5 and a mounting screw 6 attached thereto, and FIG. 2 shows a cable attached to the shell 4. A top view of the clamp 5 attached with the mounting screw 6 is shown. U-shaped portion 51 that holds the cable (not shown) of the saddle-shaped cable clamp 5
is perpendicular to the center line d of the shell 4 and is symmetrical, but the tongue piece 52 of the mounting portion is located at the center point e of the U-shaped portion 51 such that the left side is downward and the right side is upward in the figure.
They are unevenly distributed symmetrically to each other. A block 43 having a clamp mounting surface 41 and a screw hole 42 of the shell 4 is also arranged diagonally within the clamp area to correspond to the saddle-shaped cable clamp 5, but the other diagonal portion 43 is It has become a void. When the saddle-shaped cable clamp 5 is attached to one shell 4 attached with the mounting screw 6 and the other shell 4' of the same type facing each other, the other shell 4' is attached to the head 61 of the mounting screw 6. Since the gap parts face each other, they do not interfere with each other, and the second
As can be seen from the figure, if the side wall shape 44 of the block including the mounting surface 41 of the shell 4 and the shape 53 of the opposing part of the saddle-shaped cable clamp 5 are made as shown in the figure, not only the head 61 of the mounting screw 6 but also the saddle shape can be formed. It does not interfere with the cable clamp 5 either. FIG. 3 shows the cross section A-A in FIG. The depth of the screw hole 42 is made large without any retraction.

Furthermore, if the depth of the screw hole is required, it is also possible to make the mounting surface protrude from the reference surface c. A cross-sectional view similar to the previous one is shown in FIG. 4, but if the side wall shapes of the protruding parts of the shells 7 and 7' are matched to the cavity shape of the mating part, and the U-shaped part of the saddle-shaped cable clamp is made shallow, the cavity bottom surface 71 can be formed. The mounting surface 91 can be made to protrude to a region obtained by subtracting the plate thickness of the saddle-shaped cable clamp 8 and the head height of the mounting screw 9 from '' (b from the reference surface c).

(Effects of the invention) Although this invention is constructed as described above, the depth of the screw hole can be improved by appropriately unevenly distributing the shape of the saddle-shaped cable clamp and the position of the mounting screw even in the case of thin shells that are hermaphroditic. This makes it possible to determine the value extremely effectively.
