Description

The present invention relates to a connector comprising a housing and terminals housed in a terminal storage chamber of the housing.

Conventionally, a connector in which terminals are housed in a terminal storage chamber of a housing has been proposed. For example, one of the conventional connectors is provided with a locking piece (so-called lance) for locking the terminal inserted in the terminal accommodating chamber at the regular insertion position in the housing, and the terminal is locked with this locking piece. , The terminal is fixed in the terminal accommodating chamber (see, for example, Patent Document 1).

Japanese Patent No. 3468351

By the way, the terminal housed in the housing of the connector has a shape and a structure designed to make an appropriate electrical connection with the terminal on the other side to be connected. In other words, the housing has a different shape and structure for each terminal used so that it can properly accommodate terminals having such various shapes and structures. As an example, a connector used for an automobile wire harness generally has a housing having a special shape and structure that differs depending on the specifications of the mating connector and the mating terminal to be connected, even if the connector has the same purpose. Designed to be. However, from the viewpoint of reducing the complexity of connector management and manufacturing cost, it is desirable to standardize the shape and structure of the housing as much as possible.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector having a housing capable of appropriately accommodating terminals having various shapes and structures in the housing.

In order to achieve the above-mentioned object, the connector according to the present invention is characterized by the following [1] to [3].
[1]
A connector comprising a housing having a terminal accommodating chamber and terminals accommodating in the terminal accommodating chamber.
The housing is
It has an elastically deformable pressing portion that extends from the inner wall surface of the terminal accommodating chamber toward the inside of the terminal accommodating chamber and presses and contacts the terminal.
The terminal is
In a state of being pressed by the pressing portion and held in the pressing direction, the terminal accommodating chamber is accommodated.
Must be a connector.
[2]
The connector according to the above [1].
The housing has a locking piece that locks the terminal to the regular insertion position.
When the terminal is in the regular insertion position, it can be assembled to the housing without interfering with the locking piece, and when the terminal is in the middle insertion position until reaching the regular insertion position, the locking piece can be assembled. Further equipped with a front holder that interferes with and hinders assembly to the housing.
The front holder is
It has a holding portion that is arranged so as to sandwich the pressing portion with the terminal when assembled to the housing.
Must be a connector.
[3]
In the connector described in [2] above,
The front holder is
It has a protrusion that protrudes from the inner wall surface of the front holder facing the pressing portion toward the terminal and comes into contact with the terminal.
Must be a connector.

According to the connector having the configuration of [1] above, the terminal accommodating chamber of the housing has an elastically deformable pressing portion that extends from the inner wall surface of the terminal accommodating chamber toward the inside of the terminal accommodating chamber and presses and contacts the terminal. , Will be provided. The terminal is accommodated in the terminal accommodating chamber in a state of being pressed by the pressing portion and held in the pressing direction. Therefore, even if terminals of various shapes (for example, the dimensions in the direction of being sandwiched between one inner wall surface and the other inner wall surface are different) are inserted into the terminal accommodating chamber, the pressing portion is elastic while pressing and contacting the terminals. By deforming the terminal, it is possible to suppress the positional deviation (so-called rattling) of the terminal in the terminal accommodating chamber. That is, the housing can be shared regardless of the shape of the terminal or the like. Therefore, the connector of this configuration can appropriately accommodate terminals having various shapes and structures in the housing.

The above-mentioned pressing portion may have, for example, a cantilever-like shape extending from one inner wall surface of the terminal accommodating chamber, or a double-sided beam-like shape extending from the inner wall surface thereof. It may have other elastically deformable shapes.

According to the connector having the configuration of [2] above, when the front holder is assembled to the housing, the pressing portion is sandwiched between the holding portion of the front holder and the terminal. Therefore, for example, even when an unintended external force is applied to the terminal when the connector is used (for example, when a peripheral component comes into contact with an electric wire extending from the terminal), the pressing portion is deformed in a direction away from the terminal. Is suppressed by the holding part. As a result, the state in which the terminals are properly accommodated in the terminal accommodating chamber is maintained, and unintended misalignment of the terminals and the like are suppressed.

According to the connector having the configuration of [3] above, a protrusion is provided on the inner wall surface of the front holder so as to face the pressing portion of the housing and come into contact with the terminal housed in the terminal storage chamber. As a result, the terminal and the protrusion come into contact with each other with a higher contact pressure than when the terminal simply contacts the inner wall surface of the front holder or the terminal accommodating chamber. As a result, the positional deviation of the terminals is suppressed more firmly.

According to the present invention, it is possible to provide a connector having a housing capable of appropriately accommodating terminals having various shapes and structures in the housing.

The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through the embodiments described below (hereinafter referred to as "embodiments") with reference to the accompanying drawings. ..

<Embodiment>
Hereinafter, the connector 1 according to the embodiment of the present invention shown in FIGS. 1 and 2 will be described with reference to the drawings. Hereinafter, for convenience of explanation, as shown in FIG. 1, "front-back direction", "width direction", "vertical direction", "front", "rear", "top" and "bottom" are used. Define. The "front-back direction", "width direction", and "vertical direction" are orthogonal to each other. The front-rear direction coincides with the mating direction of the connector 1 and the mating connector 5 (see FIG. 1), and the front side (left side in FIG. 1) of the mating direction in which the mating connector 5 fits is the front side. The back side (right side in FIG. 1) in the opposite fitting direction is the rear side.

As shown in FIG. 3, the connector 1 includes a housing 2, a terminal 3 housed in the housing 2 from the rear side, and a front holder 4 mounted on the housing 2 from the front side. Hereinafter, the configurations of the components constituting the connector 1 will be described in order.

First, the terminal 3 will be described. As shown in FIG. 3, in this example, as the terminal 3 housed in the housing 2, there are two types of metal terminals (female terminals), the first terminal 3A and the second terminal 3B. Each of the first terminal 3A and the second terminal 3B has a shape extending in the front-rear direction, and has a rectangular box-shaped box portion 21 extending in the front-rear direction and a crimping portion 22 located on the rear side of the box portion 21. Have one. A mating terminal (male terminal) 43 (see FIG. 1) extending in the front-rear direction of the mating connector 5 is inserted into the box portion 21. A terminal of an electric wire (not shown) is crimped and fixed to the crimping portion 22.

The first terminal 3A and the second terminal 3B have different overall shapes including the height of the box portion 21. The height of the box portion 21 is between the bottom surface (lower end surface, flat surface) of the box portion 21 and the uppermost position of the box portion 21 (the protruding end of the protrusion if the upper surface of the box portion 21 has a protrusion). The vertical distance of. In this example, the height of the box portion 21 of the second terminal 3B is larger than the height of the box portion 21 of the first terminal 3A. Hereinafter, when it is not necessary to distinguish between the first terminal 3A and the second terminal 3B, the first terminal 3A and the second terminal 3B are collectively referred to as the terminal 3.

Next, the housing 2 will be described. As shown in FIG. 3, the resin housing 2 includes a housing body 11 having a substantially rectangular tubular shape. By inserting the housing body 11 into the rectangular tubular hood portion 42 (see FIG. 1) of the mating side housing 41 of the mating side connector 5, the housing 2 and the mating side housing 41 (that is, the connector 1 and the mating side) are inserted. It is designed to fit (with the side connector 5).

As shown in FIGS. 3 and 4, a plurality of terminal accommodating chambers 12 for accommodating the terminals 3 are formed inside the housing main body 11 so as to extend in the front-rear direction. In this example, a plurality of terminal accommodating chambers 12 are provided so as to be arranged in two upper and lower stages in the width direction. Each terminal accommodating chamber 12 is a space extending in the front-rear direction and having a substantially rectangular cross section.

The terminal 3 is inserted into the terminal accommodating chamber 12 from the rear side (see FIGS. 4 and 6). When the connector 1 and the mating connector 5 are fitted, the mating terminal 43 of the mating connector 5 is inserted into the box portion 21 of the terminal 3 housed in the terminal accommodating chamber 12, so that the terminal 3 and the mating side are inserted. The terminal 43 will be electrically connected.

As shown in FIG. 4, each terminal accommodating chamber 12 is provided with a lance 14, which is a cantilever-shaped locking piece, extending forward from the front end portion of the upper inner wall that partitions the terminal accommodating chamber 12. ing. The lance 14 extends diagonally from the upper inner wall surface 13 (plane extending in the front-rear direction) of the terminal accommodating chamber 12 toward the lower side (inside of the terminal accommodating chamber 12).

A gap 15 is secured above the lance 14. Therefore, the lance 14 can be elastically deformed upward so as to narrow the gap 15 from the normal posture (posture shown in FIG. 4) that is not elastically deformed. The lance 14 exerts a function of preventing the terminal 3 housed in the terminal storage chamber 12 from coming off to the rear side (details will be described later).

Further, as shown in FIG. 4, each terminal accommodating chamber 12 is provided with a cantilever-shaped elastic piece 17 extending forward from the front end portion of the lower inner wall that partitions the terminal accommodating chamber 12. .. The elastic piece 17 extends diagonally from the lower inner wall surface 16 (plane extending in the front-rear direction) of the terminal accommodating chamber 12 toward the upper side (inside of the terminal accommodating chamber 12). In this example, the position of the base end of the elastic piece 17 (that is, the position of the front end portion of the lower inner wall that partitions the terminal accommodating chamber 12) substantially coincides with the position of the tip end of the lance 14 in the front-rear direction.

The elastic piece 17 can be elastically deformed downward from a normal posture (posture shown in FIG. 4) that has not been elastically deformed. The elastic piece 17 exerts a function of upwardly pressing and holding the terminal 3 housed in the terminal storage chamber 12. The details of the function of the elastic piece 17 will be described later.

As shown in FIG. 3, a cantilever-shaped lock arm 18 is provided at the center of the upper end surface of the housing body 11 in the width direction so as to extend rearward. The lock arm 18 is provided with a lock protrusion 19. When the connector 1 and the mating connector 5 are fitted, the lock protrusion 19 engages with the lock portion (not shown) provided in the hood portion 42 of the mating housing 41, whereby the connector 1 and the mating connector 5 are engaged. It fulfills the function of maintaining the mating state with.

Next, the front holder 4 will be described. The front holder 4 is a member that is inserted into the housing body 11 from the front side and exerts a function of detecting an intermediate insertion of the terminal 3. As shown in FIG. 3, the resin front holder 4 has a substantially rectangular flat plate-shaped front wall portion 31 extending in the vertical direction and the width direction, and extending rearwardly and in the width direction from both ends in the width direction of the front wall portion 31. A pair of substantially rectangular flat plate-shaped side wall portions 32 facing each other are integrally provided.

The front holder 4 is further spaced vertically between the pair of side wall portions 32, as shown in FIG. 4, corresponding to a plurality of terminal accommodating chambers 12 arranged so as to be arranged in two upper and lower stages in the width direction. Two substantially rectangular flat plate-shaped detection portions 33 extending rearward from the front wall portion 31 so as to face each other are integrally provided. Hereinafter, when it is necessary to distinguish between the upper and lower detection units 33, the upper and lower detection units 33 are referred to as a detection unit 33a and a detection unit 33b, respectively.

As shown in FIGS. 3 and 4, the front wall portion 31 has a plurality of insertion holes penetrating in the front-rear direction corresponding to a plurality of terminal accommodating chambers 12 arranged so as to be arranged in the width direction in two stages above and below. 34 are formed so as to be lined up in the width direction in two upper and lower stages. When the connector 1 and the mating connector 5 are fitted, the mating terminal 43 (see FIG. 1) of the mating connector 5 is inserted into the insertion hole 34.

As shown in FIG. 3, locking projections 35 are formed on each of the pair of side wall portions 32. The pair of locking projections 35 temporarily lock the front holder 4 mounted on the housing body 11 in a temporary locking position (see FIGS. 4 to 7) in cooperation with the locking portion (not shown) of the housing body 11. And, it functions to selectively lock to the main locking position (see FIG. 2) behind the temporary locking position. As shown in FIG. 4, a protrusion 36 slightly protruding downward is formed on the lower surface of each detection unit 33. The action of the protrusion 36 will be described later. The configuration of each component constituting the connector 1 has been described above.

Next, a procedure for assembling the connector 1 will be described. First, the front holder 4 is inserted into the inside of the housing body 11 from the front side through the front end opening of the housing body 11 of the housing 2, and is locked to the temporary locking position as shown in FIG.

When the front holder 4 is in the temporary locking position, the rear end portion of the detection unit 33a is located in front of the gap 15 corresponding to the lance 14 of the upper terminal accommodating chamber 12, and the rear end portion of the detection unit 33b is the lower stage. It is located in front of the gap 15 corresponding to the lance 14 of the terminal accommodating chamber 12. The detection unit 33b is located below the elastic piece 17 of the upper terminal accommodating chamber 12. The protrusion 36 of the detection unit 33a is arranged so as to face the elastic piece 17 of the upper terminal storage chamber 12 in the vertical direction, and the protrusion 36 of the detection unit 33b is arranged with the elastic piece 17 of the lower terminal storage chamber 12. They are arranged so as to face each other in the vertical direction. In this example, the vertical distance between the protrusions 36 facing each other in the vertical direction and the tip of the elastic piece 17 is slightly smaller than the height of the box portion 21 of the first terminal 3A.

Next, the terminal 3 is housed in the housing 2. Hereinafter, a case where the first terminal 3A as the terminal 3 is accommodated in the terminal accommodating chamber 12 in the upper stage of the housing 2 will be described with reference to FIGS. 4 and 5.

As shown in FIG. 4, the first terminal 3A to which the electric wire (not shown) is connected to the crimping portion 22 is inserted into the upper terminal accommodating chamber 12 from the rear side. The inserted first terminal 3A moves forward toward the normal insertion position while rubbing the bottom surface of the box portion 21 against the lower inner wall surface 16 of the terminal accommodating chamber 12. When the first terminal 3A is in the middle insertion position up to the normal insertion position (specifically, when the box portion 21 is below the lance 14), the box portion 21 pushes the lance 14 upward. Then, the lance 14 is maintained in an elastically deformed posture (that is, a state in which the gap 15 is narrowed).

As shown in FIG. 5, when the first terminal 3A reaches the normal insertion position (when the box portion 21 passes under the lance 14), the lance 14 is at the corner of the first terminal 3A (specifically, when the lance 14 passes under the lance 14). , The rear upper corner portion of the box portion 21), the lance 14 elastically returns downward and is maintained in a normal posture (posture shown in FIG. 5). As a result, the lance 14 exerts a function of preventing the first terminal 3A from coming off to the rear side by locking the corner portion of the first terminal 3A.

In the process of moving the first terminal 3A from the midway insertion position to the normal insertion position in this way, the first terminal 3A moves forward while pushing the elastic piece 17 downward. As a result, when the first terminal 3A is in the normal insertion position, as shown in FIG. 5, the elastic piece 17 is maintained in a state of being elastically deformed downward, and the first terminal 3A is elastically restored by its own elastic restoring force. The box portion 21 of the above is pressed upward toward the protrusion 36. Since the height of the box portion 21 of the first terminal 3A is smaller than that of the second terminal 3B, the amount of elastic deformation downward of the elastic piece 17 in this state is relatively small. In this example, the elastic piece 17 extends diagonally forward from the lower inner wall surface 16 of the terminal accommodating chamber 12 toward the upper side (inside of the terminal accommodating chamber 12) (see FIG. 5).

As a result, the box portion 21 of the first terminal 3A is held in a state of being sandwiched in the vertical direction by the elastic piece 17 and the protrusion 36 of the detection portion 33a, so that the first terminal 3A in the terminal accommodating chamber 12 is held. Positional deviation (so-called rattling) can be suppressed. Further, as compared with the case where the protrusion 36 does not exist on the lower surface of the detection unit 33a (that is, the upper surface of the box portion 21 of the first terminal 3A simply contacts the lower surface (flat surface) of the detection unit 33a), the box portion 21 The contact pressure reaching the contact point between the protrusion 36 and the protrusion 36 is increased. As a result, the positional deviation of the first terminal 3A is more firmly suppressed.

Further, as shown in FIG. 5, the detection unit 33b is arranged so as to sandwich the elastic piece 17 with the box portion 21 of the first terminal 3A. As a result, even when an unintended external force is applied to the first terminal 3A (for example, when a peripheral component comes into contact with an electric wire extending from the first terminal 3A), the elastic piece 17 faces downward (first). Deformation in the direction away from the terminal 3A) is suppressed by the detection unit 33b. As a result, the state in which the first terminal 3A is properly accommodated in the terminal accommodating chamber 12 is maintained.

In this way, when the first terminal 3A is accommodated in the regular insertion position of the upper terminal accommodating chamber 12, the first terminal 3A is vertically sandwiched by the upper elastic piece 17 and the protrusion 36 of the detection portion 33a. It is held in the same state as it was. Similarly, when the first terminal 3A is housed in the regular insertion position of the lower terminal storage chamber 12, the first terminal 3A is vertically sandwiched by the lower elastic piece 17 and the protrusion 36 of the detection unit 33b. It is held in a state of being. As a result, the positional deviation of the first terminal 3A in the lower terminal accommodating chamber 12 can be suppressed as in the case where the first terminal 3A is accommodated in the upper terminal accommodating chamber 12.

As described above, the case where the first terminal 3A is accommodated in the terminal accommodating chamber 12 as the terminal 3 has been described with reference to FIGS. 4 and 5. Next, a case where the second terminal 3B is accommodated as the terminal 3 in the terminal accommodating chamber 12 of the housing 2 will be described with reference to FIGS. 6 and 7.

Like the first terminal 3A, the second terminal 3B is also inserted into the terminal accommodating chamber 12 from the rear side as shown in FIG. 6, and as shown in FIG. 7, the elastic piece 17 and the detection unit are inserted at the normal insertion position. It is held in a state of being sandwiched in the vertical direction by the protrusion 36 of 33.

The height of the box portion 21 of the second terminal 3B is larger than that of the first terminal 3A. Therefore, the amount of downward elastic deformation of the elastic piece 17 when the second terminal 3B is accommodated (see FIG. 7) is the downward elasticity of the elastic piece 17 when the first terminal 3A is accommodated. It is larger than the amount of deformation (see FIG. 5). In this example, the elastic piece 17 extends forward along the lower inner wall surface 16 of the terminal accommodating chamber 12 substantially parallel to the front-rear direction (see FIG. 7).

In this way, regardless of which of the two types of terminals 3 having different heights of the box portion 21 is inserted into the terminal accommodating chamber 12, the amount of elastic deformation downward of the elastic piece 17 depends on the height of the box portion 21. By automatically adjusting the terminal 3, the terminal 3 can be held in a state of being sandwiched in the vertical direction by the elastic piece 17 and the protrusion 36 of the detection unit 33.

In this way, a desired number of terminals 3 (first terminal 3A or second terminal 3B) are sequentially inserted into the corresponding terminal accommodating chambers 12 of the housing 2 and accommodated in the regular insertion positions. When the desired number of terminals 3 have been accommodated in the regular insertion positions, the front holder 4 in the temporary locking position is pushed backward with respect to the housing 2 toward the main locking position.

Here, when all the terminals 3 inserted into the terminal accommodating chamber 12 are normally in the normal insertion positions, all the lances 14 of the plurality of terminal accommodating chambers 12 are in the normal posture (postures shown in FIGS. 5 and 7). ) Is maintained. Therefore, the rear ends of the two upper and lower detection units 33 of the front holder 4 can enter the gaps 15 of the upper and lower two stages without interfering with the lances 14 of the upper and lower stages. Therefore, in this case, the rear end portions of the upper and lower detection units 33 each enter the upper and lower two-stage gaps 15, so that the front holder 4 moves from the temporary locking position to the main locking position and is finally locked. Locked at position (see Figure 2). This completes the assembly of the connector 1.

In the state where the front holder 4 is in the main locking position, the detection unit 33 has entered the gap 15, so that the movement of the lance 14 to the upper side (the side away from the terminal 3) is restricted. As a result, so-called double locking is achieved with respect to the locking between the lance 14 and the terminal 3, and the terminal 3 can be more reliably prevented from coming off to the rear side. Even when the front holder 4 is in the main locking position, the terminal 3 accommodated in the regular insertion position of the terminal accommodating chamber 12 is vertically sandwiched by the elastic piece 17 and the protrusion 36 of the detection unit 33. It is held in a state of being.

On the other hand, when a part of the terminals 3 inserted into the terminal accommodating chamber 12 is in the mid-insertion position, the terminal accommodating chamber 12 accommodating the terminal 3 in the mid-insertion position (hereinafter referred to as the mid-insertion terminal accommodating chamber 12). ) Is maintained in an elastically deformed posture (a state in which the gap 15 is narrowed) on the upper side. Therefore, the tip of the lance 14 of the mid-insertion terminal accommodating chamber 12 interferes with the rear end of the corresponding detection unit 33, and the corresponding detection unit 33 corresponds to the lance 14 of the mid-insertion terminal accommodating chamber 12. It becomes impossible to enter. As a result, the front holder 4 cannot move from the temporary locking position to the main locking position. As described above, since the front holder 4 cannot move from the temporary locking position to the main locking position, it is possible to detect the midway insertion of the terminal 3.

The assembled connector 1 is fitted with the mating connector 5 as shown in FIG. When the mating of the connector 1 and the mating connector 5 is completed, the lock protrusion 19 of the housing 2 and the lock portion (not shown) of the mating housing 41 engage with each other to engage the connector 1 and the mating connector 5. The mating state with is maintained. In addition, the terminal 3 and the mating terminal 43 are electrically connected by inserting the mating terminal 43 of the mating connector 5 into the box portion 21 of the terminal 3 housed in the terminal accommodating chamber 12. ..

<Action / effect>
As described above, according to the connector 1 according to the present embodiment, the terminal accommodating chamber 12 of the housing 2 extends from the lower inner wall surface 16 of the terminal accommodating chamber 12 toward the inside of the terminal accommodating chamber 12 and presses against the terminal 3. An elastic piece 17 that is elastically deformable is provided. The terminal 3 is accommodated in the terminal accommodating chamber 12 in a state of being pressed by the elastic piece 17 and held in the vertical direction (pressing direction). Therefore, even if two types of terminals 3 (first terminal 3A and second terminal 3B) having different heights of the box portion 21 are inserted into the terminal accommodating chamber 12, the elastic piece 17 is elastic while pressing and contacting the terminal 3. By transforming to, it is possible to suppress the positional deviation (so-called rattling) of the terminal 3 in the terminal accommodating chamber 12. That is, the housing 2 can be shared regardless of the shape of the terminal 3 or the like. Therefore, the connector 1 according to the present embodiment can appropriately accommodate the terminal 3 having various shapes and structures in the housing 2.

Further, according to the connector 1 according to the present embodiment, when the front holder 4 is assembled to the housing 2, the elastic piece 17 is sandwiched between the detection unit 33 of the front holder 4 and the terminal 3. Therefore, for example, even when an unintended external force is applied to the terminal 3 when the connector 1 is used (for example, when a peripheral component comes into contact with an electric wire extending from the terminal 3), the elastic piece 17 is separated from the terminal 3. The detection unit 33 suppresses the deformation in the upward direction (upward). As a result, the state in which the terminal 3 is properly accommodated in the terminal accommodating chamber 12 is maintained, and unintended misalignment of the terminal 3 is suppressed.

Further, according to the connector 1 according to the present embodiment, a protrusion protruding from the lower surface of the detection unit 33 of the front holder 4 so as to face the elastic piece 17 of the housing 2 and contacting the terminal 3 housed in the terminal storage chamber 12. A portion 36 is provided. As a result, the contact pressure extending to the contact point between the terminal 3 and the protrusion 36 is increased as compared with the case where the terminal 3 simply comes into surface contact with the inner wall surface of the front holder 4 or the terminal accommodating chamber 12. As a result, the positional deviation of the terminal 3 is suppressed more firmly.

In the above embodiment, the front holder 4 is included in the component of the connector 1. On the other hand, the front holder 4 may be omitted. Further, in the above embodiment, two types of terminals 3 (first terminal 3A and second terminal 3B) having different heights of the box portion 21 are inserted into the terminal accommodating chamber 12. On the other hand, three or more types of terminals 3 having different heights of the box portion 21 may be inserted into the terminal accommodating chamber 12.
