Description

The present invention relates to a connector member capable of connecting wire harnesses used, for example, in automobiles.

Conventionally, electric wires with terminals have been used as power lines and signal lines in fields such as automobiles, office automation equipment, and home appliances. In particular, in the automobile field, vehicles are rapidly becoming more sophisticated and functional, and the number of various electrical devices and control devices installed in vehicles is increasing. Accordingly, the number of electric wires with terminals used is also on the rise, and wire harnesses in which multiple electric wires with terminals are bundled together are used.

Here, wire harnesses may be divided into sub-harnesses for each group of equipment. In this way, one wire harness can be manufactured more efficiently by dividing it into multiple sub-harnesses. In addition, the number and types of connectors, terminals, and wires are limited, making it easier to meet the application conditions of the manufacturing equipment.

In this case, with conventional connectors, manual post-fitting work is required in the wire harness assembly process, resulting in the use of many connectors with a small number of poles. For example, if there is a circuit that spans subs, post-fitting may be necessary (manual work in a post-process where the subs are joined together), and the more post-fitting there is, the more processing labor is required and the greater the risk of incorrect insertion. On the other hand, taking measures such as dividing the connector or dividing the circuit will lead to increased processing and parts costs and will also worsen the ease of fitting on the vehicle assembly line.

To improve the efficiency of such work by dividing into sub-sections, for example, a lever-type split connector has been proposed (Patent Document 1).

JP 2000-228247 A

However, conventional lever-type split connectors can only be divided into about three parts, making it difficult to accommodate more sub-connectors. In addition, each divided female connector is a predetermined size, which determines the number of sub-connectors, limiting the freedom to divide the connectors into sub-connectors and reducing versatility.

The present invention was made in consideration of these problems, and aims to provide a connector member that is highly versatile and has a high degree of freedom in subdivision.

To achieve the above-mentioned object, the first invention is a connector member comprising a first housing capable of receiving a plurality of male terminal-equipped electric wires, and a second housing capable of receiving a plurality of female terminal-equipped electric wires and connectable to the first housing, the first housing having a plurality of housing accommodating sections in which the second housings are accommodated, a plurality of the second housings can be connected to one of the first housings, and each of the plurality of housing accommodating sections has approximately the same shape.

The second invention is a connector member comprising a first housing capable of receiving a male bus bar member, and a second housing capable of receiving a plurality of female terminal-equipped electric wires and connectable to the first housing, the first housing having a plurality of housing accommodating sections, a plurality of the second housings connectable to one of the first housings, the bus bar member is arranged to straddle the plurality of housing accommodating sections, a portion of the bus bar member is cuttable, and the plurality of housing accommodating sections each have approximately the same shape.

In the first and second inventions, it is preferable that the second housings have the same shape, and that each of the second housings has a different mis-insertion prevention structure for each of the housing accommodation sections to be connected.

In this case, as the mis-insertion prevention structure, a protrusion may be formed on the outer periphery of the second housing, a groove may be formed on the inner surface of the housing accommodating portion, and the second housing having the protrusion of a shape corresponding to the shape of the groove formed on the inner surface of the housing accommodating portion may be accommodated in the housing accommodating portion.

In addition, as the mis-insertion prevention structure, a plurality of protrusions that can be folded individually are formed on the outer periphery of the second housing, and grooves of different shapes are formed on the inner surface of the housing accommodating portion, and by removing some of the protrusions from the plurality of second housings, it is possible to form different arrangements of the protrusions for each of the second housings, and the second housing having the protrusions that correspond to the shapes of the grooves formed on the inner surface of the housing accommodating portion may be accommodated in the housing accommodating portion.

In addition, as the mis-insertion prevention structure, a guide member having a protrusion on the outer periphery can be attached to the outside of the second housing, and grooves of different shapes are formed on the inner surface of the housing accommodating portion. By attaching different guide members to multiple second housings, it is possible to form different arrangements of the protrusions, and the second housing having the protrusions corresponding to the shapes of the grooves formed on the inner surface of the housing accommodating portion can be accommodated in the housing accommodating portion.

As the mis-insertion prevention structure, a retainer for fixing the plurality of female terminal-attached electric wires can be attached to the second housing, the retainer having a protrusion on the outer periphery, and grooves of different shapes are formed on the inner surface of the housing accommodating portion, and by attaching different retainers to the plurality of second housings, it is possible to form different arrangements of the protrusions, and the second housing having the protrusions corresponding to the shapes of the grooves formed on the inner surface of the housing accommodating portion can be accommodated in the housing accommodating portion.

According to the first invention, multiple second housings can be connected to the first housing, and the shapes of the housing receiving portions in which the second housings are received are all the same, so the components of the second housing can be shared and the required number of second housings can be connected to the first housing. This makes it possible to obtain a so-called wire-to-wire connector structure that is highly versatile and has a high degree of freedom in subdivision.

The second invention also provides a joint connector structure that has the same effect as the first invention and can electrically connect adjacent terminal-equipped electric wires to each other using a bus bar member.

In addition, in the first and second inventions, even if all the second housings have the same shape, if each second housing has a different anti-misinsertion structure for each housing accommodation section to which it is connected, it is possible to prevent erroneous insertion.

In addition, if grooves of different shapes are formed on the inner surface of each housing receiving section, and multiple protrusions that can be individually folded are formed on the outer periphery of the second housing as a structure to prevent incorrect insertion, only the second housing in which the grooves and protrusions match can be inserted into the target housing receiving section. This prevents the second housing from being inserted incorrectly. In this case, the same second housing can be shared, which helps prevent an increase in the number of different parts.

In addition, if grooves of different shapes are formed on the inner surface of each housing accommodating section, and a guide member with a protrusion on the outer periphery can be attached to the outside of the second housing as a structure to prevent incorrect insertion, then by replacing only the guide member, only the second housing in which the groove and protrusion positions match can be inserted into the target housing accommodating section. This prevents incorrect insertion of the second housing. In this case, the same second housing can be shared, which helps prevent an increase in the number of parts.

In addition, grooves of different shapes are formed on the inner surface of each housing accommodating section, and a retainer for fixing a female terminal-equipped wire can be attached to the second housing as a structure to prevent incorrect insertion. If the retainer has a protrusion on the outer periphery, then by replacing only the retainer, only the second housing in which the groove and protrusion positions match can be inserted into the target housing accommodating section. This prevents incorrect insertion of the second housing. In this case, the same second housing can be shared, which prevents an increase in the number of parts.

The present invention provides a connector member that is highly versatile and has a high degree of freedom in subdivision.

FIG. FIG. 11A and 11B are diagrams showing a method of attaching the guide member 19 to the second housing 5c. 13A to 13D are views showing a method of attaching the retainer 25 to the second housing 5d. 4A and 4B are diagrams showing a method of connecting a first housing 3a and a second housing 5. FIG.

Below, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a connector member 1. The connector member 1 is a so-called wire-to-wire connector that can connect wire harnesses together, and is composed of a first housing 3 to which multiple male terminal-equipped electric wires can be attached, and multiple second housings 5 to which multiple female terminal-equipped electric wires can be attached.

Multiple second housings 5 can be connected to the first housing 3. In other words, the connector member 1 is a member for connecting multiple electric wires with male terminals and multiple electric wires with female terminals together. In the following figures, unless otherwise specified, illustrations of electric wires with terminals are omitted.

The first housing 3 is provided with a plurality of housing accommodating sections 7. Each housing accommodating section 7 accommodates an individual second housing 5. In other words, as described above, a single first housing 3 can be connected to a plurality of second housings 5.

The housing accommodation sections 7 are partially partitioned by protrusions 8 formed on the top and bottom, and all housing accommodation sections 7 are continuous spaces except for the protrusions 8. The parallel direction of the second housing 5 is the width direction of the first housing 3 and the second housing 5, and the side-by-side direction of the terminal-equipped electric wires in the second housing 5 is the vertical direction of the first housing 3 and the second housing 5. Here, the multiple housing accommodation sections 7 are configured with approximately the same shape (same width). In other words, the spacing between the protrusions 8 that separate the housing accommodation sections 7 (at the end, the spacing between the protrusions 8 and the side wall) is all approximately the same. It is desirable that the multiple housing accommodation sections 7 are all configured with the same shape (same width).

In the illustrated example, the first housing 3 has six housing accommodating sections 7, but the number of housing accommodating sections 7 (the number of connections of the second housing 5) is not particularly limited. In addition, the second housing 5 has four terminal accommodating sections (wires with female terminals) that can be connected in the vertical direction, but the number of wires with terminals that can be connected to one second housing 5 is not limited to the illustrated example.

2(a) and 2(b) are vertical cross-sectional views showing a method for connecting the first housing 3 and the second housing 5. As described above, a plurality of electric wires 9 with male terminals are arranged in the first housing 3, and male terminals protrude into the housing receiving portion 7. A plurality of electric wires 11 with female terminals are arranged in the second housing 5. The male terminals and female terminals are connected by inserting the second housing 5 into the housing receiving portion 7 of the first housing 3. In other words, the wire harnesses are connected to each other.

Figure 3(a) is a front view of the second housing 5 inserted into the first housing 3 (the illustration of the electric wires with terminals is omitted). As mentioned above, the size of the housing receptacles 7 is the same for all of the housings. In addition, all of the second housings 5 have approximately the same shape (same width). In other words, the same materials can be used for all of the second housings 5.

As shown in FIG. 3(b), a second housing 5a formed by connecting multiple second housings 5 may be used. The second housing 5a is formed by connecting, for example, a pair of second housings 5, and a groove is formed at the connecting portion to avoid the protrusion 8 that separates the housing accommodating portion 7 described above. In this way, it is also possible to use a second housing 5a formed by connecting multiple second housings 5.

As described above, the connector member 1 of this embodiment allows multiple second housings 5, etc. to be inserted into a first housing 3 having housing accommodating portions 7 of approximately the same shape, providing high versatility and a high degree of freedom in subdivision.

Next, we will explain the misinsertion prevention structure for preventing the second housing from being inserted incorrectly into each housing accommodating portion 7 of the first housing 3 for the connector member 1 of this embodiment. Note that the following explanation will be based on the second housing 5 having the same shape, but it can also be applied to the second housing 5a.

Figure 4 (a) shows the second housing 5b. The second housing 5b has a configuration substantially similar to that of the second housing 5, but differs in that each second housing 5b can be formed with a different mis-insertion prevention structure for each housing accommodation section 7 to be connected.

As shown in FIG. 4(a), in this embodiment, the mis-insertion prevention structure is protrusions 13 formed in multiple locations. In the illustrated example, four protrusions 13 are formed on the upper surface of the second housing 5b, spaced apart in the width direction. Note that the locations and number of the protrusions 13 are not limited to the illustrated example. For example, protrusions may be provided on the lower surface side as long as they are on the outer periphery of the second housing 5b, and the number of protrusions 13 may be three or less.

As shown in FIG. 4(b), all four protrusions can be easily removed by bending them individually. In the illustrated example, the protrusion 13 at the front is bent and removed. In this case, the remaining three protrusions 13 remain.

Figure 5 is a diagram showing the shape of the upper part of each housing accommodation section 7 of the first housing 3. Grooves 15 of different shapes are formed on the inner surface of the upper part of the housing accommodation section. In other words, the positions of the grooves 15 relative to the housing accommodation section 7 are different. It is to be noted that not only the arrangement of the grooves 15 but also the number of grooves 15 may be changed.

As described above, the second housing 5b has a plurality of protrusions 13 formed on the upper surface, and each of the protrusions 13 can be removed individually. Therefore, by removing some of the protrusions 13 from a plurality of second housings 5b, it is possible to form a different arrangement of the protrusions 13 for each of the second housings 5b. For example, by removing two of the four protrusions 13 and changing the position of the removed protrusions 13 for each of the second housings 5b, it is possible to change the arrangement of the protrusions 13 in six different ways.

If the number of housing accommodating portions 7 of the first housing 3 is greater, a greater number of configurations can be formed by adding not only the second housing 5b with two protrusions remaining, but also the second housing 5b with three protrusions remaining. Also, if the number of protrusions 13 initially formed is increased to five or more, it can be adapted to even more types.

In this way, by arranging the protrusions 13 differently for each of the multiple second housings 5b, only the second housings 5b having protrusions 13 arranged in a manner that corresponds to the shape of the grooves 15 formed on the inner surface of each housing accommodating portion 7 can be accommodated in that housing accommodating portion 7. This makes it possible to prevent erroneous insertion of the second housings 5b. Note that even if the arrangement of the protrusions 13 as a structure for preventing erroneous insertion differs for each second housing 5b, in the present invention, they are considered to have the same shape as long as the size (width and height) of the rest of the main body is the same.

In addition, when a second housing 5b of the same shape is used, if the second housing 5b has a structure to prevent incorrect insertion, it is possible to prevent the first housing 3 from being inserted into the housing accommodation portion 7 in the wrong position.

In addition, as a structure to prevent erroneous insertion, by arranging multiple protrusions 13 that can be folded individually on the outer circumferential surface of the second housing 5b, the second housing 5b can be handled as a common part during manufacturing and handling. Even in this case, by changing the protrusions 13 to be folded and removed (protrusions 13 that are not folded and are left) for each second housing 5b, it is possible to make it possible to insert only into housing accommodating sections 7 that have grooves 15 in the corresponding positions.

In the above embodiment, an example in which the protrusion 13 is removed by bending it has been described, but the protrusion 13 may be deformed rather than being completely removed. For example, as an insertion prevention structure, protrusions 13 that can be individually deformed may be formed on the outer periphery of the second housing 5b, and the protrusions 13 may be deformed for multiple second housings 5b to give each second housing 5b a different protrusion 13 shape. Even in this case, a second housing 5b having a protrusion 13 with a shape corresponding to the shape of the groove 15 formed on the inner surface of the housing accommodating portion 7 can be accommodated in the housing accommodating portion 7.

Next, a second embodiment of the mis-insertion prevention structure will be described. Figure 6 shows a second housing 5c having a mis-insertion prevention structure. In the following description, components having the same functions as those in the first embodiment are given the same reference numerals as in Figures 1 to 5, and duplicated descriptions will be omitted.

The second housing 5c has a similar configuration to the second housing 5b, but differs in that it uses a guide member 19. The guide member 19 has a guide protrusion 23 on the underside. The upper surface of the second housing 5c is formed with a guide groove 17 into which the guide protrusion 23 can be slidably inserted. In other words, the guide member 19, which is a structure to prevent erroneous insertion, can be attached to the upper part of the second housing 5c.

A number of protrusions 21 are formed on the top surface of the guide member 19. In this way, it is possible to attach the guide member 19 having the protrusions 21 on its outer periphery to the outside of the second housing 5c, so that the protrusions 21 can be arranged on the top surface of each of the second housings 5c.

As described above, grooves 15 of different shapes are formed on the inner surface of the upper part of the housing accommodating portion 7. By attaching different types of guide members 19 (different arrangements of protrusions 21) to multiple second housings 5c, it is possible to form different arrangements of protrusions 21 for each second housing 5c. In other words, a second housing 5c having protrusions 21 that correspond to the shape (arrangement) of the grooves 15 formed on the inner surface of the housing accommodating portion 7 can be accommodated in the housing accommodating portion 7.

In the above description, an example in which two protrusions 21 are arranged on each guide member 19 has been shown, but the number of protrusions 21 is not particularly limited. For example, only one protrusion 21 may be arranged on each guide member 19. Even with a single protrusion 21, by slightly shifting the arrangement together with the corresponding groove 15, only the second housing 5c whose positions match each other can be inserted into the target housing accommodating section 7.

In addition to the arrangement of the protrusions 21, the thickness and height of the protrusions 21 may be changed for each guide member 19. The arrangement of the protrusions 21 and the depth of the grooves 15 in the connection direction between the second housing 5c and the first housing 3 can also be used to prevent erroneous insertion.

According to the second embodiment, it is possible to obtain the same effect as the first embodiment. In the second embodiment, the second housings 5c can all be made of a common material, but multiple types of guide members 19 are required. However, since only multiple types of guide members 19, which are small components, need to be used, storage and handling are easier than when multiple types of second housings 5c are used.

Next, a third embodiment of the mis-insertion prevention structure will be described. Figure 7 shows a second housing 5d having a mis-insertion prevention structure. The second housing 5d has a structure similar to the second housing 5, but differs in that it uses a retainer 25.

A retainer 25 for fixing a plurality of female terminal-equipped electric wires 11 (see FIG. 2) can be attached to the second housing 5d. The retainer 25 has a protrusion 27 on the outer periphery. For example, the protrusion 27 is formed at a portion that contacts the upper portion of the second housing 5d. In other words, since the retainer 25, which has a structure for preventing erroneous insertion, can be attached to the second housing 5d, the protrusion 27 can be disposed on the upper surface of each of the second housings 5d.

As described above, grooves 15 of different shapes are formed on the inner surface of the upper part of the housing accommodating portion 7. By attaching different types of retainers 25 (different arrangements of protrusions 27) to multiple second housings 5d, it is possible to form different arrangements of protrusions 27 for each second housing 5d. In other words, a second housing 5d having protrusions 27 that correspond to the shape (arrangement) of the grooves 15 formed on the inner surface of the housing accommodating portion 7 can be accommodated in the housing accommodating portion 7.

In the above description, an example in which two protrusions 27 are arranged on each retainer 25 is shown, but as in the second embodiment, the number of protrusions 27 is not particularly limited. In addition, the size of the protrusions 27 may be changed.

According to the third embodiment, it is possible to obtain the same effect as the second embodiment. As in the second embodiment, the second housings 5d can all be made of the same material, but multiple types of retainers 25 are required. However, since only multiple types of retainers 25, which are small materials, need to be used, storage and handling are easier than when multiple types of second housings 5d are used.

In each of the above-described embodiments, the connector member is an intermediate connector (a so-called wire-to-wire connector) for connecting wire harnesses, but the connector member of the present invention can also be used as a so-called joint connector that can electrically connect adjacent terminal-equipped wires.

Figure 8 (a) is a cross-sectional view in the width direction showing the connector member 1a. The connector member 1a is composed of a first housing 3a to which a male bus bar member 29 can be attached, and a second housing 5 to which multiple electric wires with female terminals 11 can be attached. The second housing 5 can be connected to the first housing 3a. Note that the second housings 5a to 5d can also be applied.

The first housing 3a is provided with a plurality of housing accommodation sections 7 in which the second housing 5 is accommodated. Therefore, a single first housing 3 can be connected to a plurality of second housings 5. As described above, the housing accommodation sections 7 are partially partitioned by the protrusions 8 formed on the top and bottom, and all of the housing accommodation sections 7 are continuous spaces except for the protrusions 8. Here, the multiple housing accommodation sections 7 are configured with approximately the same shape (size). In other words, the spacing between the protrusions 8 that separate the housing accommodation sections 7 (at the ends, the spacing between the protrusions 8 and the side wall) is all approximately the same. Even in this case, it is desirable that the multiple housing accommodation sections 7 are all configured with the same shape (width).

The busbar member 29 is arranged so as to straddle multiple housing accommodating sections 7. For example, as shown in the figure, the busbar member 29 is arranged so as to straddle the entire width direction, and a portion of the busbar member 29 can be cut off. For example, the first housing 3a has a recess or hole formed between adjacent housing accommodating sections 7, and the busbar member 29 can be cut at that portion. Therefore, the busbar member 29 can be cut off at the cutting portion 31, and arranged so as to straddle adjacent housing accommodating sections 7 at a portion other than the cutting portion 31.

A part of the bus bar member 29 protrudes into the housing accommodating portion 7 to become a male terminal. That is, as shown in FIG. 8(b), when the second housing 5 is inserted into the first housing 3a, the female terminal of the electric wire with female terminal 11 and the bus bar member 29 are connected. At this time, the male terminals of some adjacent bus bar members 29 are connected to each other, so that the desired adjacent electric wires with female terminals 11 can be connected to each other.

In addition, by forming the above-mentioned mis-insertion prevention structure on the second housing 5 and forming a groove 15 at the desired position on the first housing 3a, the correct second housing can be inserted into the specified housing accommodating portion 7 for the connector member 1a as well.

As described above, the connector member 1a can be used as a joint connector. The busbar member 29 may be capable of conducting electrical wires 11 with female terminals not only in the width direction but also in the vertical direction.

Although the embodiment of the present invention has been described above with reference to the attached drawings, the technical scope of the present invention is not limited to the above-mentioned embodiment. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally fall within the technical scope of the present invention.
