Description

  The present invention relates to a wire relay connector having a pair of males and females of the same shape and the same size (hereinafter referred to as “male and female body”), which is mainly used for relaying electric wires such as relaying power lines.

  Wire relay connectors with different male and female shapes (gender and male variants) are widely used. However, if there are male and female connectors in the connection, males and females must be selected so as to match the shape of the mating connector to be connected, requiring unnecessary cost and assembly work.

  In addition, although it is not the relay connector of a power supply line like this invention, the shape of the hermaphroditic connector is described in the following patent documents 1 and 2 etc., for example.

Japanese Patent Laid-Open No. 9-147952 JP 2001-307846 A

  In the first place, it is considered that the reason why the conventional relay connector is a sexually different body is to avoid erroneous connection. However, in order to manufacture a male / female relay connector, at least two male and female outer frame molds and two male and female terminal (electrode) molds are required, which is costly.

  However, in order to avoid mistakes and nonconformities in connection, there are methods such as categorizing by changing the color of the relay connector, changing the shape of the part, and changing the diameter. Therefore, the relay connector does not necessarily have to be a male and female, but rather is conventional. It is thought that the relay connector is only for the reason that male and female varieties have been widely used for a long time.

  The problem to be solved by the present invention is to provide a male and female body, that is, a wire relay connector having the same shape and size.

In order to solve the above problems, an electric wire relay connector according to the present invention includes a substantially cylindrical outer cylindrical body 1 having the same male and female shape, and a terminal 4 for connecting an electric wire therein, and the outer cylindrical body 1 includes The lock portion 2 and the guard portion 3 are provided to face each other and protrude from the cylindrical body, and the guard portion is configured in a plate shape or a wave shape so as to guide the counterpart lock portion, and the lock portion The body part of the outer cylinder located at the rear is provided with a fitting part 9 into which the locking part on the other side is fitted when the male and female are coupled,
On the other hand, the internal terminal 4 is formed by bending a single metal plate, and two plate-like or corrugated projections 5 and 6 having different lengths are provided in parallel with each other, and the longer one is at the time of male-male coupling. The protrusions 5 are fitted into the spaces of the two protrusions on the other side, so that the terminals are electrically connected and fixed.

  In this case, when one terminal is provided inside the outer cylindrical body, a single-pole relay connector is provided, and when a plurality of terminals are provided, a multi-pole relay connector is provided. In the case of multipoles, the terminal is not hermaphroditic, but the outer cylinder is also included in the hermaphroditic in the present invention in the sense that there is no distinction between male and female.

  These relay connectors are applied to, for example, a relay portion of a power line. In the relay connector according to the present invention, each of the outer cylinder and the terminal is hermaphroditic (same type and same size), so that the mold can be shared and inventory management is facilitated.

  In order to prevent erroneous connection, it is preferable to give different coloring to the outer cylinder.

  Since the wire relay connector according to the present invention has the same male and female shape and size, the outer cylinder and the terminal mold can be shared by both male and female, and can be manufactured at a lower cost than conventional ones. The assembly work is also easy.

(First embodiment) -Single-pole wire relay connector-
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a plan view (partially sectional view) showing a state (coupled state) in which a pair of hermaphroditic connectors 10 are fitted to each other. The hermaphroditic connector literally has no distinction between a male body and a female body and each means an electrical connector of the same shape and size, but for convenience, the female body and the male body are distinguished. Therefore, in the drawings, the same reference numerals (numerals) are used for corresponding parts of males and females, but subscripts (A, a) are used for female bodies in order to distinguish whether each component is female or male. The male body is subscripted (B, b), and the outer insulator parts forming the outer shape of the connector are indicated by capital letters, such as A and B, and the inner terminal parts are indicated by a, b. It shall be expressed in lower case.

  As shown in FIG. 1, male and female outer cylinders 1A and 1B are made of cylindrical insulating members, and terminals 4a and 4b are inserted therein. As shown in this figure, the protruding portions of the respective connectors and terminals are fitted and fixed to the mating portions on the other side.

FIG. 2 is a plan view showing a state where the male and female connectors are separated. As shown in this figure, of the outer cylindrical body 1A (1B) of the female (male) connector, about two-thirds of the whole from the end is the cylindrical body, and the rest is the lock part 2A (2B) and the guard. The portions 3A (3B) are opposed to each other and partially protrude from the cylindrical body.
Note that the shape of the guard portion 3A (3B) may be, for example, a slightly wide plate shape or a wave shape. Moreover, it is good to set a lock | rock part to the width | variety of the grade which just fits into the groove | channel (9A (9B) in FIG. 3) of the other party outer cylinder.

  Since the outer cylinder is made of, for example, resin, the lock portion is elastic and has a restoring force in the elastic limit range. On the other hand, the center portion of the cylinder is provided with a groove for guiding the lock portion 2A (2B) and a fitting portion (9A (9B) in FIG. 3) for fitting the lock portion of the mating connector when coupled. It is provided in a part of the body part, and the vicinity of the end part of the cylindrical body is a part for connecting the electric wire to the terminal, so that the diameter is slightly smaller than that of the central body part.

The terminal 4a (4b) inserted into the male and female outer cylinders 1A (1B) is formed by bending one terminal plate, and is connected to a terminal connecting portion 7a (for connecting an electric wire exposed from the covering of the electric wire). 7b), a wire fixing portion 8a (8b) for fixing the electric wire from above the coating, a body portion in which a flat plate is folded in two to provide a parallel space inside, and plate-like protruding portions having different lengths 5a (5b) and 6a (6b).
In addition, you may make the shape of protrusion part 5a (5b), 6a (6b) into a wave shape instead of plate shape. Further, in order to guide both connectors to each other and make it easy to couple them together, the distal ends of the lock portions 2A (2B), the guard portions 3A (3B), the protruding portions 5a (5b), and 6a (6b) are shown in the figure. You may comprise so that an inward taper as shown by 2 grade | etc., May be provided.

  3A and 3B are overall perspective views of each connector, and the internal terminals are indicated by broken lines. As shown in these drawings, the lock portion 2A (2B) is provided with a claw-like barb at the rod-shaped tip and is elastic. Therefore, when the male and female outer cylinders are joined, the lock portion 2A (2B) Is a mechanism that snaps into the mating portion 9B (9A) on the other side.

  On the other hand, the plate-like protrusions 5a (5b) and 6a (6b) having different lengths are provided in parallel with each other, and the longer protrusions 5a (5b) are connected to each other on the other side. By fitting into the space of the protruding portion, the terminals are electrically connected to each other and are also physically coupled and fixed.

  4A is a front view showing a state (coupled state) in which a pair of hermaphroditic connectors 10 are fitted to each other, and FIG. 4B shows a cross-sectional view taken along line AA of FIG. 4A. ing. Further, FIG. 5 shows a cross-sectional view taken along line BB of FIG. In particular, FIG. 4 (b) well represents the state of coupling of the outer cylinder and the terminal.

6 (a) to 6 (c) are views showing a male-female connection state of terminals inside the hermaphroditic connector, FIG. 6 (a) is a perspective view, FIG. 6 (b) is a side view, and FIG. 6 (c). Is a bottom view.
As described above, the terminal 4a (4b) has plate-like protrusions 5a (5b) and 6a (6b) of different lengths provided in parallel to each other, and the longer protrusion 5a (5b) is mutually connected. Since it fits and is fixed in the space of the protrusion part of the other party, it does not appear in FIG. 6 (a) thru | or (c).

The rear end portion is provided with a terminal connecting portion 7a (7b) that is electrically connected by peeling off the coating of the electric wire, and an electric wire fixing portion 8a (8b) for fixing the electric wire from above the coating.
FIG. 7 shows a state in which the electric wire is connected to the terminal 4a (4b).

  As described above, according to the present invention, since the male and female connectors have the same shape, one outer cylinder and one terminal mold are sufficient. Therefore, the manufacturing cost can be greatly reduced, and inventory management becomes easy.

  In addition, when using as a relay connector of the power supply line to an electric circuit, you must avoid the mistake of a connection of a positive electrode and a negative electrode. One solution is to color the outer cylinder of the connector (for example, the positive electrode is red and the negative electrode is black). Alternatively, the same terminal may be used and outer cylinders having different diameters may be used. For example, the diameter of the negative electrode may be slightly larger than the diameter of the positive electrode to prevent erroneous connection. In this case, since the same terminal is used, a common mold can be used, so only two types of outer cylinder molds are required.

(Second embodiment) -Multipole wire relay connector-
If the shape of the outer cylinder is changed and a plurality of terminals are arranged in the same male and female outer cylinder in which multipolar terminals are accommodated, not only a single-pole relay connector but also a multipolar relay connector is possible. At this time, in order to prevent erroneous connection, the outer cylinder may be color-coded and the size may be changed.

  In addition, when the wire relay connector according to the present invention is applied to a bundle of a plurality of wires, the appearance of the main body part of the hermaphroditic relay connector of the present invention is decorated to the extent that the function of the hermaphrodite is not impaired to identify each wire. You may make it distinguish by applying (this is true without distinguishing between single pole and multipole).

  Since the wire relay connector according to the present invention is the same type and the same size without discrimination between males and females, it can be manufactured at a low cost because the mold can be made common, and the burden of inventory management is reduced. Is extremely large.
