Description

The present invention relates to a connector.

In recent years, as the connector has become smaller, the thickness of the electric wire connected to the connector has also become thinner, so that the flexibility of the electric wire has increased. Therefore, in this type of connector, when the electric wire is inserted into the connector, the electric wire is liable to be bent, which makes it difficult to attach the electric wire to the connector. In order to solve such a problem, in Patent Document 1, together with the crimp terminal, a finger hook portion for preventing the electric wire from bending is provided at the end of the electric wire. The finger hook portion of Patent Document 1 extends in a direction away from the crimp terminal and is arranged so as to overlap the electric wire.

The pair of wall portions has an inclined portion inclined so that the height in the third direction perpendicular to the first direction and the second direction becomes lower toward the detaching direction. ing.

Further, in the inclined portion of the pair of wall portions, the distance between the pair of wall portions is narrowed in the insertion direction in order to guide the end portion of the electric wire to the space between the pair of wall portions. It is preferable that the structure is as follows.

Further, the guide portion further has a bottom portion connecting the pair of wall portions in the third direction, and the bottom portion further toward the detachment direction from the end portion of the pair of wall portions on the detachment direction side. It is preferably extended.

Further, a terminal is attached to an end portion of the electric wire, the terminal has a protrusion protruding in a direction perpendicular to the axial direction of the electric wire, and the guide portion is the electric wire in the internal space. In order to prevent the end of the electric wire from rotating around an axis extending in the first direction when the end of the wire is inserted, a groove-like shape extending in the first direction is guided by the protrusion. It is preferable to further provide a terminal guide portion.

Hereinafter, the connector according to the embodiment of the present invention will be described with reference to the drawings. The embodiments shown below are merely examples, and the connector of the present invention is not limited to the following embodiments. In the attached drawings, parts having the same function are designated by the same reference numerals.

As an example thereof is shown in FIG. 1, the connector 1 of the present embodiment is a connector that is electrically connected to the end WE of the electric wire W, and has an accommodating portion 2 that accommodates the end WE of the electric wire W. It is provided with a guide portion 3 for guiding the end portion WE of the electric wire W to the opening 2a of the accommodating portion 2. The connector 1 has a housing, and a housing portion 2 and a guide portion 3 are provided in a part of the housing. Although not shown, the housing of the connector 1 further has a fitting portion into which a connection target such as a mating connector is fitted. The shape and structure of the housing of the connector 1 are not particularly limited. The material of the housing of the connector 1 is, for example, an engineering plastic such as PBT (polybutylene terephthalate), but is not particularly limited as long as it has an insulating property and a strength capable of inserting the electric wire W.

As will be described later, the connector 1 is electrically connected to the electric wire W by inserting the end portion WE of the electric wire W into the accommodating portion 2 through the guide portion 3. By electrically connecting the connector 1 and the electric wire W, a connector structure including the connector 1 and the electric wire W can be obtained. The other connection partner of the connector 1 is not shown, but if the connector 1 is one of the male and female connectors (for example, a female connector), the connection partner is the other of the male and female connectors (for example, a male connector). The connector 1 is preferably used for a display device such as a liquid crystal display or an organic EL display, or an electronic device such as a mobile device such as a mobile phone or a tablet terminal, which is particularly required to be miniaturized. Is not particularly limited.

In the present specification, the direction in which the electric wire W is inserted into the connector 1 is referred to as an insertion direction D11, the direction in which the electric wire W is withdrawn from the connector 1 is referred to as a detachment direction D12, and both the insertion direction D11 and the detachment direction D12 are collectively referred to. It is called the first direction D1. Further, one direction perpendicular to the first direction D1 is referred to as a second direction D2. In the present embodiment, the second direction D2 is the direction in which the pair of wall portions 31 of the guide portions 3 face each other. Further, the direction perpendicular to both the first direction D1 and the second direction D2 is referred to as a third direction D3. In the present embodiment, the third direction D3 is the height direction of the wall portion 31 of the guide portion 3. Further, in the present specification, when the terms "upper" and "lower" such as "upper" and "lower" are used, the direction in which the guide portion 3 opens along the third direction D3 is referred to as "up". , The opposite is called "bottom".

The accommodating portion 2 extends in the first direction D1 and includes an internal space 2s in which the end portion WE of the electric wire W is arranged. The end portion of the internal space 2s on the detachment direction D12 side has an opening 2a into which the end portion WE of the electric wire W is inserted toward the internal space 2s, and the internal space 2s extends from the opening 2a in the insertion direction D11. ing. In the present embodiment, the internal space 2s is a space on the insertion direction D11 side of the space between the pair of wall portions 31 of the guide portion 3. Further, the opening 2a is an entrance of the internal space 2s located at the end of the internal space 2s on the departure direction D12 side, and in the present embodiment, the space between the internal space 2s and the pair of wall portions 31 of the guide portion 3. It is a boundary part with 3s.

In the present embodiment, as shown in FIG. 1, the number of the accommodating portions 2 is a plurality (two), and the accommodating portions 2 are in the second direction D2 in which the wall portions 31 of the guide portions 3 face each other. It is provided in parallel with. The number of accommodating portions 2 is not particularly limited, and is provided according to the number of electric wires W connected to the connector 1. Therefore, the number of the accommodating portions 2 may be one.

In the present embodiment, as shown in FIG. 1, the internal space 2s of the accommodating portion 2 is defined by a plurality of accommodating wall portions 21, 22, 23, 24. Specifically, the accommodating portions 2 include first and second accommodating wall portions 21 and 22 provided apart from each other in the third direction D3, and third and fourth accommodating walls separated from each other in the second direction D2. It has portions 23 and 24, and a rectangular parallelepiped internal space 2s is defined by the first to fourth accommodating wall portions 21 to 24. The cross-sectional shape of the internal space 2s (cross-sectional shape perpendicular to the first direction D1) is not particularly limited, and may be substantially rectangular or substantially circular as in the present embodiment. Further, the length of the accommodating portion 2 in the first direction D1 is at least an example of an electrical connection portion of the end portion WE of the electric wire W (for example, FIG. 1 shows an example) from the viewpoint of ensuring sufficient insulation. It is preferably longer than the exposed portion of the lead wire W1, the terminal W3 whose example is shown in FIG. 8), but it may be changed as appropriate according to other specifications required for the connector 1.

The accommodating portion 2 has a locking portion (not shown) such as a claw that locks the end portion WE of the electric wire W inserted into the internal space 2s at a predetermined position to prevent the electric wire W from coming off. You may be doing it. Further, the accommodating portion 2 has an opening (not shown) at an end portion (end portion on the insertion direction D11 side) opposite to the opening 2a provided on the detachment direction D12 side of the first direction D1. The terminal or the like of the mating connector is inserted into the accommodating portion 2 through the opening on the insertion direction D11 side, and the connector 1 and the mating connector to be connected are connected.

As an example thereof is shown in FIG. 1, the guide portion 3 is provided on the detaching direction D12 side with respect to the accommodating portion 2, and a pair of guide portions 3 are arranged apart from each other with the space 3s in the second direction D2. It has a wall portion 31. In the present embodiment, the guide portion 3 further has a bottom portion 32 connecting the pair of wall portions 31 in the third direction D3. The "wall portion" referred to here is a portion that guides the end portion WE of the electric wire W to the opening 2a of the accommodating portion 2 in the second direction D2. The "bottom" is a portion below the third direction D3 that guides the end WE of the electric wire W to the opening 2a of the accommodating portion 2. As an example of the guide portion 3 is shown in FIG. 4, from the viewpoint of miniaturization of the connector 1, the position of the end portion of the guide portion 3 on the detachment direction D12 side is the end of the entire connector 1 on the detachment direction D12 side. It is preferably formed so as to coincide with the position of the portion 1a. However, as an example is shown in FIG. 5A, the end of the electric wire W is such that the connector 1 has a bottom portion 32 extending further toward the detachment direction D12 from the end portion of the pair of wall portions 31 on the detachment direction D12 side. When inserting the portion WE, the end portion of the guide portion 3 and the end portion 1a of the connector 1 may not be aligned if there is no obstacle. When the guide portion 3 has a bottom portion 32 extending in the detaching direction D12, the end portion WE can be easily inserted into the space 3s between the pair of wall portions 31 by aligning the end portion WE with the bottom portion 32. ..

In the present embodiment, the guide portion 3 is formed continuously with the accommodating portion 2 in the first direction D1 as shown in FIG. 6, and the space 3s of the guide portion 3 is in the detaching direction from the opening 2a of the accommodating portion 2. It extends towards D12. However, the guide portion 3 may be discontinuous in the first direction D1 with respect to the accommodating portion 2 as long as the end portion WE of the electric wire W can be guided to the internal space 2s of the accommodating portion 2. For example, a gap may be formed in the first direction D1 between the pair of wall portions 31 of the guide portion 3 and the end faces of the accommodating portion 2, so that the guide portion 3 and the accommodating portion 2 are discontinuous. ..

The pair of wall portions 31 sandwich the end portion WE of the electric wire W in the second direction D2 before the end portion WE of the electric wire W is inserted into the internal space 2s of the accommodating portion 2, and the electric wire W heading toward the accommodating portion 2. The end WE of the is moved stably. The separation distance between the pair of wall portions 31 in the second direction D2 is not particularly limited, but is, for example, 0.5 mm to 2.5 mm, preferably 0.5 mm to 1.5 mm. The pair of wall portions 31 are open upward. Therefore, when the end WE of the electric wire W is inserted into the guide portion 3, the state of the end WE of the electric wire W can be visually observed, so that the operator does not forcibly insert the electric wire W into the accommodating portion 2. Prompted by. As a result, the bending of the electric wire W is suppressed. In the present embodiment, the pair of wall portions 31 are provided in a plate shape, but if they can be inserted by sandwiching the end portion WE of the electric wire W, a cylinder extending in the first direction D1 and opening above the third direction D3. The shape, such as the shape, is not particularly limited.

The wall portion 31 has an inclined portion 31a that is inclined so that the height in the third direction D3 becomes lower toward the detaching direction D12, as an example thereof is shown in FIGS. 1 and 6. By providing the inclined portion 31a on the wall portion 31, the operator can insert the end portion WE of the electric wire W into the accommodating portion 2 while keeping the finger F along the inclined portion 31a (see FIG. 9A). As a result, the electric wire W is prevented from bending. The prevention of bending of the electric wire W will be described in more detail later. The inclination angle θ of the inclined portion 31a with respect to the first direction D1 is not particularly limited as long as the operator's finger F (see FIG. 9A) can be aligned, but when the end portion WE of the electric wire W is inserted into the accommodating portion 2. From the viewpoint of preventing back bending, it is preferably 30 ° to 60 °, and more preferably 40 ° to 50 °. Further, the inclined portion 31a does not have to be an inclined portion that is linearly inclined at a constant angle as shown in FIG. 6, and may be curved and inclined as shown in FIGS. 7A and 7B. Good. For example, the inclined portion 31a may have a curved inclination in which the inclination angle θ of the inclined portion 31a gradually increases toward the separation direction D12, as shown in FIG. 7A. Further, the inclined portion 31a may have a curved inclination in which the inclination angle θ of the inclined portion 31a gradually decreases toward the separation direction D12, as shown in FIG. 7B.

The inclined portion 31a has a wall toward the insertion direction D11 in order to guide the end portion WE of the electric wire W to the space 3s between the pair of wall portions 31, as an example thereof is shown in FIGS. 1 and 4. It may have an auxiliary guide portion 31b in which the interval between the portions 31 is narrowed. The auxiliary guide portion 31b facilitates that the end portion WE of the electric wire W enters between the pair of wall portions 31 when the end portion WE of the electric wire W is inserted in the insertion direction D11 toward the guide portion 3. In the present embodiment, the auxiliary guide portion 31b is formed by an inclined plane as shown in FIGS. 1 and 4, but may be curved. Further, the auxiliary guide portion 31b may be formed on a part of the inner surface of the wall portion 31 as shown in FIGS. 1 and 4, and extends over the entire inner surface of the wall portion 31 as shown in FIG. 5B. May be formed. The auxiliary guide portion 31b may be formed not only on the wall portion 31 but also on the bottom portion 32.

The distance between the auxiliary guide portions 31b is short in the direction toward the bottom 32 in the third direction D3. As a result, the end WE of the electric wire W can be easily inserted between the pair of wall portions 31 from above toward the bottom portion 32.

The bottom portion 32 is arbitrarily provided in the guide portion 3, and connects the pair of wall portions 31 downward in the second direction D2. When the bottom portion 32 is provided, when the end portion WE of the electric wire W is inserted into the accommodating portion 2, the bottom portion 32 supports the end portion WE of the electric wire W from below the third direction D3. As a result, the bending of the electric wire W is further prevented.

The electric wire W inserted into the connector 1 is not particularly limited, but as an example thereof is shown in FIG. 1, for example, a conductive linear wire W1 and a direction in which the conductive wire W1 extends. On the other hand, it is composed of an insulating coating W2 that covers the conducting wire W1 in the circumferential direction. The electric wire W used in the present embodiment has flexibility, and its thickness is preferably relatively thin. Specifically, the diameter of the electric wire W (including the insulating coating W2) is, for example, 0.1 mm to 2.0 mm, preferably 0.1 mm to 1.0 mm, but is not particularly limited. The lead wire W1 is preferably a stranded wire generally having flexibility, but may be a single wire.

The end WE of the electric wire W is not particularly limited as long as the electric wire W can be electrically connected to the connector 1. For example, in the example shown in FIG. 1, the lead wire W1 is exposed at the end WE of the electric wire W by removing the insulating coating W2. Since the electric wire W becomes more flexible as it becomes thinner, when the electric wire W is relatively thin, the electric wire W tends to bend when it is inserted into the accommodating portion 2. Further, as an example thereof is shown in FIG. 8, the terminal W3 may be attached to the exposed lead wire (not shown in FIG. 8) at the end WE of the electric wire W. The terminal W3 is not particularly limited, but is, for example, a crimp terminal. Since the terminal W3 is generally made of bent metal, it has higher rigidity than the electric wire W. Therefore, when the end portion WE of the electric wire W is inserted, stress is likely to be concentrated on the boundary portion between the electric wire W composed of two members having different rigidity and the terminal W3, and the electric wire W is likely to be bent at this portion.

When the terminal W3 is used as the end WE of the electric wire W, the terminal W3 has a protrusion W31 protruding in a direction perpendicular to the axial direction of the electric wire W, and the guide portion 3 is an internal space of the accommodating portion 2. It is preferable to further include a groove-shaped terminal guide portion 33 extending in the first direction D1 to which the protrusion W31 is guided when the end portion WE of the electric wire W is inserted into the 2s. By doing so, it is possible to prevent the end WE of the electric wire W from rotating around the axis extending in the first direction D1, so that it becomes easier to guide the end WE to the internal space 2s of the accommodating portion 2. .. The terminal guide portion 33 can be provided at an arbitrary location of the guide portion 3 such as a pair of wall portions 31 or a bottom portion 32, depending on the installation location of the protrusion W31 of the terminal W3. As shown in FIG. 8, when the bottom portion 32 is provided so as to extend further toward the detachment direction D12 from the end portion of the pair of wall portions 31 on the detachment direction D12 side, the extending bottom portion 32 is provided. It is also preferable that the terminal guide portion 33 is also provided. By doing so, it is possible to prevent the end WE from rotating even before the end WE of the electric wire W is inserted into the pair of wall portions 31, so that the end WE can be accommodated in the internal space 2s of the accommodating portion 2. It will be easier to guide you to.

As an example is shown in FIG. 8, the connector 1 may be attached to a base material B such as a housing or a substrate. Depending on the external shape and / or size required for the connector 1 when the connector 1 is attached to the base material B, the connector 1 may have a stepped portion 1s exposed in the detaching direction D12. In the present embodiment, the step portion 1s is a surface that connects the upper surface of the accommodating portion 2 and the surface including the bottom portion 32 of the guide portion 3 and extends in the second direction D2 around the guide portion 3. In such a case, if the opening 2a of the accommodating portion 2 is provided in the step portion 1s and the guide portion 3 is provided so as to extend from the step portion 1s in the detaching direction D12 by using the step portion 1s, the shape of the connector 1 can be formed. The guide portion 3 can be provided in the connector 1 in a space-saving manner with almost no change in the dimensions.

Next, with reference to FIGS. 9A and 9B, an example of the behavior of the electric wire W at the time of insertion into the connector 1 of the present embodiment and at the time of insertion into the connector 10 of the comparative example will be described. The following description of the behavior of the electric wire W is merely an example, and the behavior of the electric wire in the present invention is not limited by the following description.

As shown in FIG. 9B, in the connector 10 generally connected to the end WE of the electric wire W, the operator holds the electric wire with the finger F and moves from the insertion direction D11 to the accommodating portion 12 of the connector 10. Insert the end WE of the electric wire W. At that time, a gap G is generated between the operator's finger F and the end portion 10a of the connector 10 perpendicular to the insertion direction D11. As described above, as the connector 10 is miniaturized, the thickness of the electric wire W connected to the connector 10 is also reduced, so that the flexibility of the electric wire W is increased. Since there is nothing to support the electric wire W in this gap G, the force in the insertion direction D11 deviates to the second direction D2 and / or the third direction D3, and it is difficult to transmit the force to the electric wire W well. Therefore, the electric wire W is likely to bend in the second direction D2 and / or the third direction D3, and the electric wire W is likely to be bent. This makes it difficult to attach the electric wire W to the connector 10.

On the other hand, the connector 1 according to the present embodiment is a pair of wall portions 31 arranged apart from each other in the second direction D2 on the detaching direction D12 side of the accommodating portion 2, as an example thereof is shown in FIG. 9A. The pair of wall portions 31 has an inclined portion 31a that is inclined so that the height in the third direction D3 is low. Therefore, when the operator inserts the end portion WE of the electric wire W toward the internal space 2s of the accommodating portion 2 while holding the electric wire W with the finger F, one finger F is aligned with the inclined portion 31a. Can be placed. In this way, there is almost no gap between one finger F and the electric wire W, and the electric wire W follows the finger F. As a result, the electric wire W can be supported by the finger F, so that the electric wire W can be prevented from bending.

When inserting the electric wire W, the pair of wall portions 31 preferably support the electric wire W in the second direction D2, and the bottom portion 32 preferably supports the electric wire W from below the third direction D3. As a result, the force in the insertion direction D11 does not deviate to the second direction D2 and / or the third direction D3, and the force in the insertion direction D11 can be easily transmitted to the electric wire W. As a result, the bending of the electric wire W in both the second direction D2 and the third direction D3 is further prevented.

Further, in the connector 1 according to the present embodiment, as an example thereof is shown in FIG. 1 and the like, the auxiliary guide portion 31b is preferably provided so that the distance between the wall portions 31 becomes narrower toward the insertion direction D11. It is provided. When the auxiliary guide portion 31b is provided, when the end portion WE of the electric wire W is inserted into the internal space 2s of the accommodating portion 2 from the insertion direction D11, the end portion WE of the electric wire W is walled by the auxiliary guide portion 31b. It is easily guided to the space 3s between the portions 31. The end WE of the electric wire W can be inserted not only from the insertion direction D11 but also from above the third direction D3. When the end WE of the electric wire W is inserted from above, the auxiliary guide portion 31b is inclined along the finger F, so that the end WE of the electric wire W can be easily inserted into the guide portion 3. Further, since the pair of wall portions 31 are open upward, the state of the end portion WE of the electric wire W can be visually observed when the end portion WE of the electric wire W is inserted into the guide portion 3. Then, while visually observing the guide portion 3, the end portion WE of the electric wire W can be sandwiched between the pair of wall portions 31, and then inserted into the accommodating portion 2. As a result, the attention of the operator is drawn, and the bending of the electric wire W is further suppressed.

When the force in the insertion direction D11 is transmitted to the electric wire W, if the finger F is placed on the upper portion 1b of the connector 1 as shown in FIG. 9A, the finger F can be more easily aligned with the electric wire W. In the present embodiment, the accommodating portion 2 is provided at the upper end of the connector 1 (the end portion of the third direction D3), and the first accommodating wall portion 21 defining the internal space 2s of the accommodating portion 2 is formed in a plate shape. .. This makes it easier to align the finger F with the connector 1. The thickness 21t of the first accommodating wall portion 21 is not particularly limited, but is 0.1 mm to 1.0 mm, for example, considering the mechanical strength of the accommodating portion 2 to which the end WE of the electric wire W can be inserted. It is preferable to have.
