The present invention relates to a connector for connecting to a wire harness arranged in an automobile, and more particularly, to a joint connector for connecting a circuit in a connector connected to a terminal of each wire harness to establish a circuit connection. By using parts, the connector can be easily adapted to the shape and circuit connection form of the connector and provided at a low cost.
[0002]
[Prior art]
Conventionally, in this type of joint connector, as shown in FIGS. 19A and 19B, a dedicated joint bus bar 1 is formed by stamping a metal plate, and a joint pin 1b is connected to the connector 2 by a joint conducting portion 1a.

[Problems to be solved by the invention]
As described above, since the joint bus bar 1 is a dedicated part for each connector, if a circuit change occurs and the shape of the joint bus bar needs to be changed, a new mold must be manufactured, which increases the cost. It is a factor.
Further, when connecting the terminals of the upper and lower cavities, the joint pins need to have a wide surface (the plate surface direction) horizontal, so as shown in FIG. Although it is bent in the shape of a letter, if there are three or more steps in the same upper and lower rows, there is a problem that one metal plate cannot be bent and formed.
[0006]
The present invention has been made in view of the above-described problem, and instead of using a joint busbar as a dedicated part formed by using a mold, the existing general-purpose product is used to reduce the cost, and the wide surface of the joint pin is used. It is an object of the present invention to secure electrical connection reliability by making contact with a counterpart terminal and to easily cope with a change in circuit connection.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a method for punching a metal plate and then bending the metal plate to project a male crimp terminal in parallel with a band-shaped carrier at a fixed interval via a narrow cutting part. Using the terminal member that is installed and manufactured,
The terminal member is cut into a plurality of crimp terminals as a set at the cutting and dividing portion, the carrier is used as a joint conducting portion, the male terminal portion of the crimp terminal is used as a joint pin, and the length of the carrier is set. A joint terminal material is formed by twisting the cutting and splitting portion so that the wide surface of the joint pin is orthogonal to the direction and / or bending between adjacent crimp terminal protruding portions of the carrier. ,
For a connector in which a plurality of cavities are arranged in parallel in a plurality of upper and lower stages and a plurality of cavities are arranged in parallel in each stage, the joint pin is inserted and locked in the upper and lower cavities with the joint conductive portion of the joint terminal material in the up and down direction, A connector having a configuration in which a female terminal of a mating connector that fits into a female terminal is fitted with the joint pin, and the wide surface of the joint pin and the female terminal are brought into electrical contact.
[0008]
In the present invention, as described above, as a joint bus bar that is inserted and locked in the connector, a manufacturing part of a male crimp terminal that is crimp-connected to an existing wire terminal is used, and each crimp terminal is continuously connected in a manufacturing process. The carrier used is a joint conduction part, and each crimp terminal is used as a joint pin. If the carrier used as the joint conducting portion is cut at a required position, a required number of joint pins can be formed as a joint bus bar protruding from the joint conducting portion, and it is possible to easily follow a change in circuit configuration. As described above, since the joint bus bar is used by using the existing production parts widely used for the electric wire connection, the production cost of the joint bus bar can be significantly reduced.
[0009]
However, when the manufacturing part with the carrier for the crimp terminal is used as it is, as shown in FIGS. 20A and 20B, the joint pin 100 inserted into the upper and lower cavities of the connector 4 ′ has a wide surface S. In this case, the electrical contact pieces 3a 'of the mating terminal 3' come into contact with the narrow surface T in the plate thickness direction, resulting in poor electrical connection reliability.
Therefore, in the present invention, the cutting and dividing portion connecting each crimp terminal and the carrier is twisted so that when the carrier is arranged up and down, the wide surface of the joint pin is horizontal, and The terminals are brought into contact with the wide surface of the joint pins to improve the electrical connection reliability.
Alternatively, instead of twisting the part for cutting and splitting, bend the carrier side and place the carrier up and down so that the wide surface of the joint pin is horizontal, and the female terminal of the other party contacts the wide surface of the joint pin The electrical connection reliability. Furthermore, the wide surface of the joint pin is in a direction orthogonal to the length direction of the carrier by using the torsion of the cutting division portion and the bending of the carrier in combination, and the wide surface of the joint pin is horizontal when the carrier is arranged in the vertical direction. You may face it.
[0010]
Specifically, in the joint terminal material, the cut and divided portion is twisted by 90 degrees, and the wide surface of the joint pin is set in the horizontal direction with respect to the joint conducting portion to be vertically inserted into the connector. The connectors are inserted and locked in the cavities in the same upper and lower rows of a plurality of stages.
That is, when the crimp terminal is used for wire connection, a cut-and-divide portion that separates from the carrier is used, and this portion is twisted by 90 degrees, so that the width of the joint pin is increased with respect to the joint conduction portion formed by the vertical and vertical carriers. The plane is horizontal. Since the cut and divided portion is narrow, it can be easily twisted by 90 degrees.
[0011]
Instead of twisting the cutting and dividing portion, the carrier side may be bent.
That is, when the carrier between the joint pins is bent in a Z-shape, the wide surface of the joint pin can be in the horizontal direction with respect to the above-described joint conducting portion inserted into the connector in the vertical direction. When the vertical portion is inclined by twisting in a Z shape, the joint pins can be inserted and locked in the cavities in the same upper and lower rows of a plurality of stages of the connector.
As described above, when the carrier side is twisted in a Z-shape, the adjacent joint pins can be positioned in the same vertical line. Also, vertical pitch adjustment between the joint pins can be performed.
[0012]
Further, instead of bending the carrier between adjacent joint pins into a Z-shape, the carrier may be bent in a step-like shape. In this case, since the joint pins are not in the same row in the upper and lower rows, the cavities in the plurality of stages of the connector into which the joint pins are inserted are the cavities in the vertically adjacent rows.
[0013]
In the case where the joint terminal material has a joint pin protruding only on one side from the joint conductive portion made of a carrier, the joint conductive portion is housed at one end of the connector housing the joint terminal material, and the other connector is connected to the other end. Are fitted and connected to the joint pin.
The joint terminal material has a joint pin protruding in both sides, or three directions, and further in four directions from a joint conduction portion made of a carrier, and is provided on both sides, three directions, or a connector for housing the joint terminal material. The mating connector may be fitted in four directions.
[0014]
When projecting joint pins on both sides from the joint conductive portion of the joint terminal material, a joint pin is formed by twisting the cutting and splitting portion by 90 degrees and then bending the carrier 90 degrees to one side and the other side by 90 degrees. With the joint pin provided, the joint pin is projected from both sides around the carrier,
A joint conductive part of the joint terminal material is vertically inserted into a center part of the connector, a wide surface of the joint pin protruding from both sides thereof is set in a horizontal direction, and a plurality of steps provided on both sides of a carrier insertion part of the connector are provided. To be inserted and locked in the cavity.
[0015]
According to the above configuration, the terminals in the connector of the wire harness terminal fitted from both sides to the connector accommodating the joint terminal material can be jointed, and diversification of circuit connection can be achieved.
When joint pins that are not bent after being twisted by 90 degrees are also used, a joint terminal material in which joint pins protrude in three directions around a joint conductive part made of a carrier can be used. It is also possible to provide a housing so that the male connector of the wire harness terminal can be fitted from three directions. Furthermore, when a joint pin which is twisted 90 degrees and then bent 180 degrees is also used, a joint terminal member having four joint pins projecting around the joint conductive portion made of a carrier may be provided.
[0016]
Further, a plurality of the above-mentioned joint terminal materials are provided, and the plurality of the joint terminal materials are formed from the above-mentioned terminal members having different crimp terminal sizes and projecting pitches with respect to the carrier. You may make it correspond with the terminal of a connector.
[0017]
The configuration of the mating connector to be fitted with the connector accommodating the joint terminal material is not limited, but includes a plurality of one-stage male connectors, and inserts and locks the plurality of male connectors with the joint terminal material. It is preferable that the female terminals are inserted and locked in the female connector, and the female terminals in a plurality of male connectors are jointed by the joint terminal material.
Also, the plurality of male connectors may be combined vertically and integrated, and then fitted into the female connector, or may be fitted separately to the connector accommodating and locking the joint terminal material. They may be locked together.
As described above, when the male connectors are combined into an integrated male connector in the up-down direction, the pitch in the up-down direction can be made large, and the pitch between the connectors can be made substantially the same as the pitch between the terminals. Therefore, the above-mentioned joint terminal members arranged in the up-down direction are suitably used for an integrated male connector.
In addition, even when the pitch between the connectors and the pitch between the terminals are not the same, the pitch of the connectors can be adjusted by changing the combination of various connectors. It is suitably used. Further, by arranging the joint terminal members in the vertical and vertical directions, it is not necessary to change the horizontal pitch of the male connector whose size is strictly controlled.
[0018]
In addition, when the circuit connection of the upper and lower stages is intended, and the circuit of the same stage is also connected, the carrier is bent at a required portion, leaving the portion for cutting and dividing or the portion where the carrier is not twisted, and the connector is bent. The joint pin composed of the crimp terminal of the untwisted portion may be inserted and locked in the same-stage cavity.
In this way, a joint terminal material capable of connecting circuits of cavities in a plurality of upper and lower stages and also in the same stage can be easily provided from existing crimp terminal manufacturing parts.

The joint pin 32a is horizontally oriented with the wide surface S of the joint pin 32a projecting while being shifted by one row.
[0036]
When the joint terminal material 32 is inserted and locked in the female connector 11, as shown in FIG. 11, the joint pins 32a are inserted and locked not in the same upper and lower row of terminal holes but sequentially in adjacent row of terminal holes. . Therefore, similarly to the terminals in the cavity of the mating connector, not the terminals in the same upper and lower rows but the adjacent terminals are sequentially joined by the joint terminal material 32.
If a joint terminal member 32 having a small number of joint pins is provided and inserted and locked in a vacant portion, the connector can be used effectively.
[0037]
12 and 13 show a fourth embodiment.
In the joint terminal material 35 of the fourth embodiment, similarly to the first embodiment, the cut-split portion 10c 'of the terminal member 10' is twisted by 90 degrees so that the wide surface 35a-1 of the joint pin 35a is oriented horizontally.

The joint pin formed by twisting 90 degrees may be left without being bent, and may be projected in three directions from the joint conductive portion together with the joint pin bent at ± 90 degrees and projected on both sides. .
Further, as shown in FIG. 14, the joint pin 48a may be projected in four directions including bending the joint pin 180 degrees.
When the joint pins protrude in these three or four directions, a female connector for housing the joint terminal material may be provided with a connector housing part projecting in three or four directions.
[0041]
15 and 16 show a fifth embodiment.
The fifth embodiment is adapted to a case where a wire harness terminal connector is composed of a hybrid male connector accommodating female terminals having different terminal sizes.
That is, when the diameter of the electric wire connecting the female terminals is different, the female terminal size is different. Therefore, it is necessary to change the size of the joint pin of the joint terminal material to be fitted and connected to the female terminal.
[0042]
Therefore, as the terminal member 10 ′, the joint terminal materials 45 and 46 are respectively formed from the plurality of terminal members 10 ′ and 10 ″ having different crimp terminal sizes in the same manner as in the second embodiment. If the size of the crimping terminal is different between 45 and 46, the projecting pitch from the carrier is also different. Therefore, the bending degree of the joint conductive portions 45b and 46b made of the carrier is adjusted so that the joint pins 45a and 46a are connected at the same pitch. It protrudes from the parts 45b and 46b.
[0043]
When the joint terminal members 45, 46 having different sizes of the above-mentioned joint pins 45a, 46a are vertically inserted into and locked in the female connector 48, the joint pins 45a, 46a having different sizes in the cavities arranged in the horizontal direction in the same stage. Can be projected, and electrical connection can be achieved in correspondence with the female connector of the hybrid.
[0044]
17 and 18 show a sixth embodiment.
In the sixth embodiment, a female terminal inserted into a plurality of cavities in the same stage and a female terminal inserted into a plurality of cavities in a plurality of upper and lower stages are joined by one joint terminal member 50.
In the joint terminal material 50, the joint conductive portion 50b made of a carrier is bent into an L shape, and the joint pin 50a-1 protruding from the horizontal joint conductive portion 50b-1 does not twist the cut and split portion, and the terminal is not twisted. While the member is kept in a manufactured state, the joint pins 50a-2 connected to the female terminals in the same row in a plurality of stages are twisted by 90 degrees as in the first embodiment.
Therefore, the wide surface of each of the joint pins 50a-1 and 50a-2 is horizontal.
[0045]
In the female connector 52 accommodating the joint terminal material 50, a partition wall having an L-shaped insertion opening 52a is provided in the joint terminal material accommodating portion, and the L-shaped joint terminal material 50 is inserted from the insertion opening 52a. Then, the joint pins 50a are protruded from the connector housing portion side in an L-shaped arrangement, and are electrically connected to female terminals (not shown) of the mating connector.
With the above configuration, not only the female terminals in the upper and lower stages but also the female terminals in the same stage can be jointed.
[0046]
In addition, by refracting the joint conductive portion made of the carrier not only to the above-mentioned L shape but also to the required shape, the required number of female terminals in which each stage is arranged in multiple poles in a plurality of upper and lower stages is required. Female terminals can be jointed with a joint terminal material.
[0047]
【The invention's effect】
As is apparent from the above description, according to the present invention, as a joint terminal material to be inserted and locked in a connector, a manufacturing part of a male crimp terminal that is crimp-connected to an existing wire terminal is used and manufactured. Since the carrier that connects each crimp terminal in the process is a joint conducting part and each crimp terminal is used as a joint pin as it is, if the carrier is cut at the required position, the required number of joint pins protrude from the joint conducting part It is possible to easily follow a change in a circuit form in which a terminal to be jointed is changed. In addition, since the joint bus bar is used by using existing production parts that are widely used for electric wire connection, labor for producing a dedicated joint bus bar product can be omitted, and the production cost can be significantly reduced.
[0048]
And, when the terminal member manufactured for the crimp terminal to be connected to the electric wire is used as a joint terminal material, the carrier is bent at a position between the joint pins by twisting at the cutting division portion, or Since the wide surface of the pin is oriented in the direction perpendicular to the joint conductive part made of the carrier, when the joint conductive part is arranged vertically and vertically, the wide surface of the joint pin can be oriented horizontally and the mating connector A large area can be brought into contact with the electric contact piece of the female terminal. Therefore, the reliability of the electrical connection with the counterpart terminal can be increased while the joint terminal material is formed using the existing terminal member.
[0049]
Further, in the case where the joint conductive portion formed of the carrier is bent, there is an advantage that the adjustment corresponding to the mating connector can be easily performed, for example, the pitch between the joint pins can be adjusted by changing the bending angle.
In particular, when the joint terminal material is arranged vertically and vertically, the pitch between the connectors and the pitch between the joint pins of the joint terminal material are matched when connecting the connectors to the terminals in an integrated connector that connects multiple connectors vertically This is advantageous in that it is not necessary to change the pitch in the lateral direction in which the dimensional control of the connector is strict.
