Description

The present invention provides, for example, an electric wire terminal housing structure comprising a terminal-attached electric wire with a terminal connected to the tip of the electric wire, and a housing for accommodating the terminal-equipped electric wire inside, and a wire terminal housing structure using the electric wire terminal housing structure. Regarding connectors.

For example, in connectors and the like, a storage structure is used that includes a terminal-equipped electric wire with a terminal connected to the tip of the electric wire, and a housing body that accommodates the terminal-equipped electric wire inside. In such a housing structure, the terminal is generally fixed at a position where the terminal contacts the connection target of the housing body, so that when the housing body and the connection target are connected, the connection target and the terminal are electrically connected. It has become.

In general, electric wires with terminals in which a terminal is connected to an exposed conductor with one end of the conductor covered with an insulation coating exposed from the insulation coating are further protected by covering the insulation coating with an outer layer. be. If only the terminal of such a wire with a terminal is fixed to the housing, there is a problem with the durability of the terminal connection part of the wire against tension, and there is also a risk that the terminal may come off from the housing due to tension. , there was a problem with the stability of the terminal connection. Therefore, the movement of the outer layer of the electric wire with respect to the housing is restricted.

For example, Patent Document 1 discloses that an electric wire attachment member including a holding part that holds the outer layer part of the electric wire and an extension part extending from the holding part is attached to the outer layer part of the electric wire, and the electric wire attachment member is attached to the outer layer part of the electric wire. A housing structure is disclosed in which the outer layer part is fixed to the housing body by locking the outer layer part to the housing body. In such a housing structure, the above-mentioned problem does not occur because the outer layer is fixed to the housing and its movement is restricted.

However, in the accommodation structure of Patent Document 1, the terminal and the wire attachment member, which are separate members, are not always provided in the same positional relationship. Therefore, the terminal may be twisted in the axial direction with respect to the wire attachment member rather than in an ideal position. In that case, when the terminal and the extension are fixed to the container, the terminal is fixed to the container with the electric wire exposed from the outer layer being twisted more than it should be.

In this case, there is a risk that a load will be applied to the wire due to unintended twisting of the wire. Further, for example, when the electric wire is a twisted electric wire, there is a possibility that various effects may occur, such as a possibility that the characteristic impedance of the electric wire is adversely affected by the twisting.

Additionally, in order to prevent unintentional twisting of the wires, it may be possible to align the connected terminals to a predetermined rotational position before attaching the wire attachment member, but this would require accurate alignment of the terminals. , leading to an increase in workload.

In view of the above-mentioned problems, the present invention provides an electric wire terminal housing structure that can prevent a load from acting on electric wires and realize a stable connection state through a terminal with a small amount of work, and a wire terminal housing structure that uses the electric wire terminal housing structure. The purpose is to provide connectors that are compatible with the market.

The present invention comprises a terminal-equipped electric wire with a terminal connected to the tip of the electric wire, and a container that houses the terminal-equipped electric wire inside, and the terminal-equipped electric wire has an outer layer part that sheathes the electric wire, and a container that houses the terminal-equipped electric wire. At the tip end side of the outer layer part, there is provided a retaining body that is attached to the electric wire and is configured of a covered electric wire exposed by peeling off the insulation coating and the terminal connected to the tip of the covered electric wire, and the detachment preventing body is attached to the electric wire. , a mounting part to be mounted on the outer layer part, and a mounting part disposed either before or after the mounting part in the axial direction of the electric wire, and in a cross direction intersecting the axial direction of the electric wire. and a protrusion protruding toward a side opposite to the side on which the electric wire is arranged , the housing body is provided with an electric wire accommodating part for accommodating the electric wire with a terminal, and the electric wire accommodating part is configured to accommodate the electric wire with a terminal. an outer layer part accommodating part for accommodating a part of the outer layer part, and a terminal fixing part for fixing the terminal, and the outer layer part accommodating part is provided with a protrusion part accommodating part for accommodating the protrusion part.

To be more specific, even when the protrusion is accommodated in the protrusion accommodating part with the mounting part attached to the outer layer part of the electric wire, the protrusion accommodating part is smaller than the protrusion in the axial direction. Since it is formed widely, it is possible to allow the outer layer portion to be shifted around the axial direction. Therefore, even if the terminal is twisted around the axial direction with respect to the retaining body than the ideal position, the retaining body is shifted around the axial direction according to the twist of the terminal. The protrusion can be accommodated in the protrusion accommodating part. Thereby, unintended twisting of the electric wire exposed from the outer layer portion can be suppressed, and a load due to such twisting can be prevented from acting on the electric wire. Furthermore, it is no longer necessary to accurately attach the wire attachment member to the terminal, and the work can be done with the same precision as normal crimping work, leading to a reduction in the amount of work.

Further, by housing the protrusion in the protrusion accommodating portion, movement of the outer layer in the axial direction can be restricted. Therefore, it is possible to prevent a tensile load from acting on the terminal connection portion of the electric wire.

Therefore, according to the present invention, it is possible to prevent a load from acting on the electric wire, and to realize a stable connection state through the terminal with a small amount of work.

Further, the protruding portion is disposed either before or after the mounting portion in the axial direction.
As a result, the protrusion is disposed either in the front or rear of the mounting part in the axial direction, so that a force can be applied to the mounting part from one direction, such as by crimping, to the outer layer part. On the other hand, when the mounting portion is mounted, the protruding portion does not interfere and the mounting can be performed reliably. This makes it possible to further simplify the assembly process.

As an aspect of the present invention, the housing is configured by combining a first housing body and a second housing body, and the terminal-equipped electric wire and the retaining body are configured by combining the first housing body and the second housing body. The protrusion accommodating portion may be formed in an opposing portion of at least one of the first accommodating body and the second accommodating body.

The above-mentioned protrusion accommodating portion is formed in an opposing portion of at least one of the first accommodating body and the second accommodating body. In addition to the case where it is formed only on one side, it includes the case where it is formed on both sides, and the case where it is formed from one side to the other.

According to the present invention, the electric wire terminal housing structure is obtained by a simple method of arranging the electric wire with a terminal and the retaining body in one of the first housing body and the second housing body, and combining the other with one of the housing bodies. be able to. This makes it possible to further simplify the assembly process.

Moreover, as an aspect of the present invention, the mounting section may be configured with a crimping section that substantially surrounds the outer layer section.
The above-mentioned "substantially surrounding" means not only the case where the mounting part surrounds the entire circumference of the outer layer part but also the case where it surrounds only a part of the whole circumference.

According to this invention, the mounting part can be attached to the outer layer part by a simple method of crimping the mounting part to the outer layer part. This makes it possible to further simplify the assembly process.

Further, as an aspect of the present invention, the crimp portion may be a cylindrical or bent barrel.
According to the present invention, since the outer layer portion is substantially surrounded by a cylindrical or bent barrel suitable for crimping, the crimping portion can be efficiently crimped onto the outer layer portion. This makes it possible to further simplify the assembly process.

Moreover, as an aspect of the present invention, the mounting portion and the protruding portion may be formed of a bent plate material.
According to this invention, the mounting portion and the protruding portion can be obtained by a simple method of bending a plate material. Thereby, the retaining body can be configured efficiently.

Further, as an aspect of the present invention, the terminal-equipped electric wire is a terminal-equipped twisted pair electric wire in which the terminal is connected to each of a pair of twisted electric wires, and the mounting portion of the retainer is a jacket of the terminal-equipped twisted pair electric wire. It may be attached to.

According to the present invention, even in the case of the twisted pair electric wire with a terminal, a stable connection state can be realized through the terminal.

In detail, twisted pair wires are a pair of wires that are twisted to cancel out the direction of the nearby magnetic field, so if unintended twisting, unraveling, or loosening of the wire occurs, the characteristics of the wire may be affected. Impedance is adversely affected and a stable connection via the terminal is inhibited. On the other hand, the electric wire terminal housing structure can suppress unintentional twisting of the electric wire, so even in the case of the twisted pair electric wire with a terminal, a stable connection state can be realized through the terminal. Furthermore, it is no longer necessary to accurately attach the wire attachment member to the terminal, and the amount of work can be done with the same precision as normal crimping work, leading to a reduction in the amount of work.

Further, the present invention is characterized in that the housing body in the above-described electric wire terminal housing structure is a connector that is a connector housing.

As shown in FIG. 1, the electric wire terminal housing structure 1 includes an electric wire 10 with a terminal, in which a terminal 12 is connected to the tip of the electric wire 11, and a retaining body 20 attached to the electric wire 10 with a terminal. 10 is provided. Then, the retaining body 20 is attached to the outer layer portion 13 of the electric wire 10 with a terminal. That is, the electric wire terminal housing structure 1 houses the electric wire 10 with a terminal, in which the terminal 12 is connected to the tip of the electric wire 11 and the retainer 20 is attached to the outer layer part 13, inside the housing body 30. .

As shown in FIG. 2, the terminal-equipped electric wire 10 is a terminal-equipped twisted pair in which a terminal 12 is electrically connected to an exposed conductor 11a exposed by peeling off the insulation coating on one end side of a pair of twisted electric wires 11, 11. It's an electric wire. In addition, the other end side of the electric wire 10 with a terminal is covered with the outer layer part 13 of the electric wires 11, 11 in a twisted state. Further, the shape of the terminal 12 is shown schematically.

In other words, the terminal-equipped electric wire 10 includes a pair of twisted electric wires 11, 11, which are covered with an outer layer portion 13 made of a jacket. The electric wires 11, 11 exposed from the outer layer portion 13 are untwisted, and a terminal 12 is electrically connected to the tip (exposed conductor 11a) of each electric wire 11.

As shown in FIGS. 3(a) and 3(b), the retaining body 20 includes a mounting portion 21 and a protruding portion 22.
The attachment part 21 is attached to the outer layer part 13 of the electric wire 11, and more specifically, the attachment part 21 is attached to the jacket as the outer layer part 13 of the terminal-equipped electric wire 10 made of a terminal-attached twisted pair electric wire. The protruding portion 22 is a portion that protrudes in a direction intersecting the axial direction L of the electric wire 11 . Note that the mounting portion 21 and the protruding portion 22 are made of bent plate material.

The mounting part 21 is composed of a crimping part that surrounds the outer layer part 13, and specifically, it is constructed so that the outer layer part 13 is surrounded by a bent barrel 21a. That is, by interposing the outer layer 13 between the opposing barrels 21a and press-bonding the barrel 21a to the outer layer 13, the barrel 21a surrounds the outer layer 13 as shown in FIG. 3(b). Then, the mounting part 21 is mounted to the outer layer part 13.

The protruding portion 22 protrudes toward the outside in the radial direction when the mounting portion 21 is mounted on the outer layer portion 13 in a direction intersecting the axial direction L. Further, it is arranged on the front side (front end side Lf) in the axial direction L with respect to the mounting portion 21 . Specifically, a plate extending from the mounting portion 21 toward the front in the axial direction L is bent in the cross direction, that is, toward the outside in the radial direction with respect to the axial direction L, so that the plate-shaped member along the axial direction L is bent in the radial direction. It is formed to protrude outward.

Next, the container 30 will be explained using FIGS. 4 to 6.
Hereinafter, when the electric wire 10 with a terminal to which the retainer 20 is attached is housed in the container 30, the direction along the axis of the electric wire 10 with a terminal will be referred to as the axial direction L. The side of the terminal-attached electric wire 10 on which the terminal 12 is arranged is called the front end side Lf, and the side opposite to the front end side Lf is called the rear end side Lb. Further, a direction perpendicular to the axial direction L and the vertical direction in FIGS. 1 and 4 is defined as a height direction H, and a direction perpendicular to both the axial direction L and the vertical direction is defined as a width direction W.

As shown in FIG. 4, the container 30 consists of two members, a first container 30A and a second container 30B, and is constructed by combining the first container 30A and the second container 30B. There is. The terminal-attached electric wire 10 and the retaining body 20 are housed in the opposing portions of the first housing body 30A and the second housing body 30B. Specifically, the first accommodating body 30A and the second accommodating body 30B are configured such that when they are combined, a space for accommodating the terminal-attached electric wire 10 and the retaining body 20 is formed in their opposing parts. ing.

The first housing body 30A is provided with a locking portion 31A that locks on a locked portion 32B provided on the second housing body 30B, and the second housing body 30B is provided with a locking portion 31A that locks on a locked portion 32B provided on the second housing body 30B. A locking portion 31B is provided that locks on a locked portion 32A provided at 30A. Thereby, by locking the respective locking parts 31A, 31B of the first housing body 30A and the second housing body 30B to the locked parts 32A, 32B of the other party, the first housing body 30A and the second housing body 30B is fixed in a combined state.

Further, the electric wire 10 with a terminal is inserted into the rear end side Lb of the first housing body 30A and the second housing body 30B in the axial direction L when the first housing body 30A and the second housing body 30B are combined. Insertion recesses 33A and 33B that function as insertion holes 33 are provided, respectively.

A terminal fixing portion 34 for fixing the terminal 12 is provided on the distal end side Lf in the axial direction L on the placement surface of the first housing body 30A on which the terminal-equipped electric wire 10 is placed. This terminal fixing part 34 is configured so that the tip of the terminal 12 is exposed to the outside when the electric wire 11 is fixed. Note that since the terminal-equipped electric wire 10 is composed of two electric wires 11 and has two terminals 12, two terminal fixing portions 34 are provided in the first housing 30A side by side in the width direction W.

Further, the mounting surface of the first container 30A is provided with an outer layer portion accommodating portion 35 for accommodating the outer layer portion 13 of the electric wire with terminal 10, and a protrusion portion accommodating portion 36 for accommodating the protrusion portion 22. . The outer layer portion accommodating portion 35 is constituted by an arcuate recess portion that is continuous with a part of the insertion recess portion 33A and extends in the axial direction L, and extends along the circumferential surface of the annular outer layer portion 13 and the mounting portion 21. There is.

The protrusion accommodating portion 36 is constituted by a rectangular recess recessed in the height direction H in order to accommodate the protrusion 22, and the length in the axial direction L and the depth in the height direction H are shown in FIG. As such, the length of the protrusion 22 in the axial direction L and the length of the protrusion in the radial direction are larger than that of the protrusion 22. By accommodating the protrusion 22 in such a protrusion accommodating portion 36, the movement of the protrusion 22 in the axial direction L is regulated. Prevents escape in direction L.

Furthermore, the protrusion accommodating portion 36 is formed wider than the protrusion 22 around the axial direction L. Specifically, the protrusion accommodating portion 36 is formed of a rectangular recess. As shown in FIG. 6, the width of the protrusion accommodating portion 36 in the width direction W is determined by the width of the terminal attached around the central axis of the terminal attached electric wire 10 when the terminal attached electric wire 10 to which the retaining body 20 is attached is placed. It is configured such that when the electric wire 10 is rotated, a region R1 through which the protrusion 22 passes is at least contained within the protrusion accommodating portion 36.

By configuring the protrusion part accommodating part 36 in this way, the electric wire 10 with a terminal can be shifted around the axial direction L while the protrusion part 22 is accommodated in the protrusion part accommodating part 36, as shown in FIG. It can be placed in the protrusion accommodating portion 36.

The second housing body 30B is a member that is combined with the first housing body 30A, and is formed in a box shape that is attached to the first housing body 30A and closes the housing space for the terminal-equipped electric wire 10 in the first housing body 30A. There is. Further, as shown in FIG. 4, the second container 30B is provided with a contact portion 37 that contacts the terminal fixing portion 34 and closes the terminal fixing portion 34 from above at a portion corresponding to the terminal fixing portion 34. There is.
Furthermore, the second container 30B has an outer layer container 38 which has the same shape as the outer layer container 35 and is formed of an arcuate recess extending in the axial direction L, and is provided at a location corresponding to the outer layer container 35. There is.

As a result, the terminal 12 comes into contact with the terminal fixing part 34 by combining the second housing body 30B from the mounting surface side of the first housing body 30A with respect to the first housing body 30A to which the electric wire 10 with a terminal is attached. The outer layer part 13 can be fixed and housed in the outer layer part 37, and the outer layer part 13 can be housed in the outer layer part accommodating part 35 and the outer layer part accommodating part 38. That is, in the container 30, the terminal fixing portion 34, the outer layer portion accommodating portions 35, 38, and the contact portion 37 constitute a wire accommodating portion that accommodates the terminal-attached electric wire 10. , an electric wire accommodating part and a protrusion accommodating part 36, which are constituted by outer layer part accommodating parts 35 and 38 and a contact part 37.

Next, an example of a process for assembling the wire terminal housing structure 1 configured as described above will be briefly described based on FIGS. 7 and 8. Here, FIGS. 7 and 8 are explanatory diagrams showing the process of assembling the wire terminal housing structure 1.

First, as shown in FIG. 7(a), the attachment part 21 of the retaining body 20 is attached to the outer layer part 13 of the electric wire 10 with a terminal by crimping. Then, as shown in FIG. 7(b), the outer layer part 13 of the terminal-equipped electric wire 10 is cut away from the attachment part 21 on the tip side Lf, the electric wires 11, 11 are exposed, and the tip of each exposed electric wire 11 is Connect terminal 12.

Subsequently, as shown in FIG. 7(c), each terminal 12 is attached to each terminal fixing part 34 of the first container 30A, and further, with the protrusion part 22 accommodated in the protrusion part accommodation part 36, the outer layer part The outer layer portion 13 of the electric wire 10 with a terminal is housed in the housing portion 35 . Then, as shown in FIG. 8(a), the second container 30B is combined with the first container 30A containing the terminal-attached electric wire 10, and as shown in FIG. 8(b), the terminal is attached to the container 30. It is assumed that the attached electric wire 10 is accommodated.
This completes the assembly of the wire terminal housing structure 1.

The electric wire terminal housing structure 1 configured in this manner can prevent a load from acting on the electric wires 11 and realize a stable connection state via the terminals 12.
To explain in detail, even when the protrusion 22 is accommodated in the protrusion accommodating part 36 with the outer layer part 13 of the electric wire 11 attached to the attachment part 21, the protrusion accommodating part 36 does not fit the protrusion 22 around the axial direction L. Since it is formed wider, it allows the outer layer portion 13 to be shifted and arranged around the axial direction L. Therefore, even if the terminal 12 is twisted around the axial direction L with respect to the retainer 20 than the ideal position, the retainer 20 can be shifted around the axial direction L according to the twist of the terminal 12. In this state, the protrusion 22 can be accommodated in the protrusion accommodating portion 36. Thereby, unintended twisting of the electric wire 11 exposed from the outer layer portion 13 can be suppressed, and a load due to such twisting can be prevented from acting on the electric wire 11.

Furthermore, by housing the protrusion 22 in the protrusion accommodating portion 36, movement of the outer layer portion 13 in the axial direction L can be restricted. Therefore, it is possible to prevent a tensile load from acting on the connection portion of the terminal 12 in the electric wire 11. Therefore, a load can be prevented from acting on the electric wire 11, and a stable connection state can be achieved via the terminal 12.

Moreover, since the container 30 is composed of the first container 30A and the second container 30B, the terminal-equipped electric wire 10 and the retainer 20 are arranged in one of the first container 30A and the second container 30B. The electric wire terminal housing structure 1 can be obtained by a simple method of combining the other with the one. This makes it possible to further simplify the assembly process.

Furthermore, since the mounting part 21 is composed of a crimping part that crimps the outer layer part 13, the mounting part 21 can be mounted to the outer layer part 13 by a simple method of crimping the mounting part 21 to the outer layer part 13. I can do it. Further, since the outer layer portion 13 is substantially surrounded by the barrel 21a suitable for crimping, the mounting portion 21 can be efficiently crimped to the outer layer portion 13. This makes it possible to further simplify the assembly process.

Moreover, since the mounting part 21 and the protruding part 22 are made of a bent plate material, the mounting part 21 and the protruding part 22 can be obtained by a simple method of bending the plate material. Thereby, the retaining body 20 can be configured efficiently.

Furthermore, since the protruding portion 22 is disposed on the distal end side Lf in the axial direction L with respect to the mounting portion 21, a force is applied to the mounting portion 21 from one direction and the mounting portion 21 is moved against the outer layer portion 13. At the time of mounting, the mounting portion 21 can be reliably mounted without the protrusion 22 interfering with the mounting. This makes it possible to further simplify the assembly process.

Further, the terminal-equipped electric wire 10 made of a terminal-equipped twisted pair electric wire can realize a stable connection state via the terminal 12 by the electric wire terminal housing structure 1 configured as described above.
To explain in detail, the electric wire 10 with a terminal, which is a twisted pair electric wire, has a pair of electric wires 11 twisted in order to cancel the directions of nearby magnetic fields. Therefore, if the pair of electric wires 11 are unintentionally twisted, unraveled, or loosened, the characteristic impedance of the electric wires 11 is adversely affected, and a stable connection state via the terminals 12 is inhibited. On the other hand, since the wire end housing structure 1 can suppress unintended twisting of the wire 11, a stable connection state of the terminal-equipped wire 10 can be realized via the terminal 12.

For example, in the above description, the terminal-equipped electric wire 10 is constituted by a terminal-equipped twisted pair electric wire, and the outer layer portion 13 is constituted by a jacket of the terminal-equipped twisted-pair electric wire, but the invention is not necessarily limited to this. For example, any type of terminal-attached electric wire 10 may be used, and any type of outer layer portion 13 may be used.

For example, in the above description, the mounting part 21 is configured to surround the outer layer part 13 by the bent barrel 21a, but the mounting part 21 is not necessarily limited to this, and any structure that can be mounted to the outer layer part 13 may be used. For example, the mounting portion 21 may have any configuration.

For example, the attachment part 21 does not need to be configured as a crimp part, and may be attached to the outer layer part 13 in another manner. When the mounting part 21 is configured as a crimping part, the mounting part 21 only needs to substantially surround the outer layer part 13, and the mounting part 21 does not necessarily have to surround the entire circumference of the outer layer part 13. Good too. In addition, when the mounting part 21 is configured as a crimping part, the mounting part 21 may be formed in a cylindrical shape and surrounding the outer layer part 13, as long as it can be crimped to the mounting part 21. It can be changed as appropriate.

Furthermore, in the above description, the protruding portion 22 protrudes radially outward in the axial direction L and is disposed on the front side in the axial direction L with respect to the mounting portion 21, but this is not necessarily the case. For example, the protrusion 22 may protrude in any direction as long as it protrudes in a direction intersecting the axial direction L of the electric wire 10 with a terminal. Further, the protruding portion 22 may be arranged on the rear side of the mounting portion 21 in the axial direction L, or may be provided at a position overlapping the mounting portion 21 in the axial direction L. Further, the specific shape thereof may be changed as appropriate as long as it protrudes in a direction intersecting the axial direction L of the electric wire 10 with a terminal.

In the above description, the mounting part 21 and the protruding part 22 are made of bent plate materials, but the mounting part 21 and the protruding part 22 may be formed by other methods such as casting. .

In the above description, the container 30 is composed of the first container 30A and the second container 30B, but it is not necessarily limited to this, and the container 30 may be composed of one member, or three It may be constructed from the above members.

The configuration of each part of the container 30 is not limited to that shown in the above description, and may be changed as appropriate. For example, the outer layer accommodating parts 35 and 38 may be changed as appropriate as long as they accommodate the electric wire 10 with a terminal, and the protrusion accommodating part 36 can also be changed so that the protrusion 22 can escape in the axial direction L. As long as it is wider than the protrusion 22 around the axial direction L, it may be changed as appropriate.

Specifically, the protrusion accommodating portion 36 is not limited to being formed in the first accommodating body 30A, but may be formed in the second accommodating body 30B, or may be formed in the first accommodating body 30A and the second accommodating body 30B. It may be formed in both. In that case, it may be provided continuously from the first container 30A to the second container 30B.

Further, if the width and shape of the protrusion housing portion 36 in the width direction W is wider than the protrusion 22 around the axial direction L, when the terminal-equipped electric wire 10 rotates around the axial direction L, The width and shape may be such that the protrusion 22 comes into contact with the inner wall surface of the protrusion accommodating portion 36 and the rotation of the terminal-attached electric wire 10 is restricted.

In addition, there are various uses for the electric wire terminal housing structure 1, and for example, the housing body 30 in the electric wire terminal housing structure 1 may be a connector configured with a connector housing. Thereby, it is possible to efficiently obtain a connector that can prevent a load from acting on the electric wire 11 and realize a stable connection state via the terminal 12 with a small amount of work.
