Description

The present invention relates to a connector comprising a terminal fitting and a housing having a terminal accommodating chamber in which the terminal fitting is housed.

Conventionally, a connector has been proposed in which a terminal fitting (for example, a female terminal) having a box portion having a built-in terminal spring is housed in a housing. In this type of connector, in general, both terminal fittings are electrically connected by pressing a terminal spring against a terminal fitting (for example, a male terminal) on the other side.

For example, one of the conventional connectors has an opening (specifically, specifically,) in the cylinder wall of the box portion in order to prevent the tip portion of the terminal spring from interfering with the cylinder wall of the box portion when connecting both terminal fittings. A through hole) is provided. As a result, even if the terminal spring pressed against the mating terminal bends toward the cylinder wall, the tip of the terminal spring enters the opening of the cylinder wall, causing interference between the tip of the terminal spring and the cylinder wall. (See, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2006-156285

In the conventional connector described above, if an external force such as vibration is applied to the connector after connecting both terminal fittings, the tip of the terminal spring may sway in the opening (through hole) of the tubular wall of the box. .. In this case, the electrical connection between both terminal fittings may become unstable due to repeated contact and separation between the terminal spring and the terminal fitting on the other side. It is desirable to avoid such a phenomenon as much as possible from the viewpoint of properly maintaining the electrical connection between both terminal fittings.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector capable of appropriately maintaining an electrical connection between terminals even when an external force such as vibration is applied.

In order to achieve the above-mentioned object, the connector according to the present invention is characterized by the following [1] to [4].
[1]
A connector comprising a terminal fitting and a housing having a terminal accommodating chamber for accommodating the terminal fitting.
The terminal fitting
A tubular box that accepts the other terminal and
It has a terminal spring provided on the box portion so as to come into contact with the mating terminal.
The contact between the terminal spring and the mating terminal deforms the terminal spring so as to bend, and the contact portion, which is at least a part of the terminal spring, passes through an opening portion provided in the tubular wall of the box portion. It is configured to come into contact with the inner wall of the terminal containment chamber.
Must be a connector.

In the connector described in [1] above,
The terminal fitting
The contact portion is configured to make contact while being embedded in the inner wall of the terminal accommodating chamber.
Must be a connector.
[3]
In the connector described in [2] above,
The housing is
The inner wall of the terminal accommodating chamber has a press-fitting portion into which the contact portion of the terminal spring is press-fitted.
Must be a connector.
[4]
In the connector according to any one of the above [1] to [3].
The terminal spring
It has a curved surface that is curved so as to be convex toward the mating terminal, and is configured so that the terminal spring is deformed so as to bend upon contact between the curved surface and the mating terminal.
Must be a connector.

According to the connector having the configuration of [1] above, when the terminal fitting housed in the connector and the terminal fitting on the other side (hereinafter referred to as "the other side terminal") are electrically connected, the terminal spring of the terminal fitting and the other side are connected. It deforms so that the terminal spring bends when it comes into contact with the side terminal. Then, the contact portion (for example, the tip end portion of the terminal spring), which is at least a part of the terminal spring, comes into contact with the inner wall of the terminal accommodating chamber through the opening portion provided in the tubular wall of the box portion of the terminal fitting. As a result, as compared with the conventional connector described above, since the tip of the terminal spring is in contact with the inner wall of the terminal accommodating chamber, even if an external force such as vibration is applied to the connector, the terminal spring is suppressed from swinging. .. Therefore, the connector having this configuration can properly maintain the electrical connection between the terminals even when an external force such as vibration is applied, as compared with the conventional connector.

According to the connector having the configuration of [2] above, the contact portion (for example, the tip portion) of the terminal spring is embedded in the inner wall of the terminal accommodating chamber (in other words, the connector is stuck in the inner wall). Therefore, the swinging movement of the terminal spring can be suppressed more firmly than when the contact portion of the terminal spring simply contacts the inner wall of the terminal accommodating chamber. Further, in the connector of this configuration, the terminal spring is supported at a plurality of places (for example, a double-sided beam shape supported by a place embedded in the inner wall of the terminal accommodating chamber and the root of the terminal spring). Therefore, the terminal spring can be firmly pressed and contacted by the mating terminal. As a result, the electrical connection between the terminals can be maintained more appropriately.

According to the connector having the configuration of [3] above, the contact portion (for example, the tip portion) of the terminal spring is press-fitted into the press-fitting portion (for example, the concave portion) provided in advance on the inner wall of the terminal accommodating chamber. Therefore, the contact portion can be embedded in the inner wall with a smaller force as compared with the case where the contact portion of the terminal spring is forcibly embedded (pierced) in the inner wall in which the press-fitting portion is not provided in advance. As a result, the force required to connect the terminal fitting and the mating terminal (so-called insertion force of the mating terminal) can be reduced, and the workability at the time of connecting the terminal fitting and the mating terminal can be improved.

According to the connector having the configuration of [4] above, when the terminal spring and the mating terminal are connected, the mating terminal comes into contact with the curved surface of the terminal spring. Therefore, for example, the mating terminal is more reliably guided to the normal position in the box portion of the terminal as compared with the case where the mating terminal comes into contact with the vicinity of the end surface of the tip of the terminal spring (for example, the punched surface by press working). You will get it. As a result, the reliability of the electrical connection between the terminals can be further improved.

As described above, according to the present invention, it is possible to provide a connector capable of properly maintaining an electrical connection between terminals even when an external force such as vibration is applied.

The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through the embodiments for carrying out the invention 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 will be described with reference to the drawings. As shown in FIG. 6A, the connector 1 includes a female terminal 10 and a female housing 30 accommodating the female terminal 10. By fitting the female housing 30 of the connector 1 and the male housing 50 of the mating connector 2, the electric wire W1 connected to the female terminal 10 housed in the female housing 30 and the male terminal housed in the male housing 50. The electric wires W2 connected to the 40 are electrically connected to each other.

Hereinafter, for convenience of explanation, as shown in FIGS. 1, 2 and 4, "front-back direction", "width direction", "vertical direction", "front", "rear", "top" and "bottom" are defined. .. The "front-back direction", "width direction", and "vertical direction" are orthogonal to each other. The front-rear direction is the mating direction between the female connector 1 (female housing 30) and the male connector 2 (male housing 50), the insertion direction of the female terminal 10 into the female housing 30, and the male terminal 40 into the male housing 50. It matches the insertion direction. For each of the connector 1 and the mating connector 2, the front side in the fitting direction in which the mating connector is fitted is the front side, and the back side in the opposite fitting direction is the rear side. Hereinafter, first, each member constituting the connector 1 will be described in order.

First, the female terminal 10 will be described. As shown in FIGS. 1 and 2, the metal female terminal 10 is formed into an elongated shape in the front-rear direction by performing a punching process, a bending process, or the like on one metal plate. In the substantially first half region of the female terminal 10, a square box portion 12 into which the male terminal 40 (specifically, the tab portion 41; see FIG. 4 (a) and the like) is inserted is formed from the opening 11 on the front surface. A barrel portion 13 for crimping the electric wire W1 is formed in a substantially latter half region of the female terminal 10.

The barrel portion 13 has a form in which a pair of front and rear crimping pieces 14 are raised from both side edges in the width direction of the bottom plate. The wire barrel 14A on the front side of the barrel portion 13 is adapted to crimp the core wire of the electric wire W1, and the insulation barrel 14B on the rear side of the barrel portion 13 is adapted to crimp the coating of the electric wire W1.

The box portion 12 has a bottom wall 15 that is elongated in the front-rear direction and is flush with the bottom plate of the barrel portion 13, a pair of side walls 16 that rise from both side edges in the width direction of the bottom wall 15, and a side wall 16 on one side in the width direction. It is composed of a ceiling wall 17 formed so as to extend from the upper end edge of the above surface to the other side in the width direction and face the bottom wall 15.

As shown in FIG. 2, the connecting portion 18 extending downward from the rear end portion of the ceiling wall 17 is arranged along the side wall 16 on the other side in the width direction, and the bottom wall 15 is arranged from the lower end edge of the connecting portion 18. A plate-shaped terminal spring 19 is arranged along the above.

The terminal spring 19 extends in a cantilever shape from the bottom wall 15 at the rear end of the box 12 toward the front (more accurately, forward and slightly upward) inside the box 12. The front end is a free end. The rear end portion of the terminal spring 19 is arranged so as to be overlapped with the bottom wall 15, and is referred to as a base end portion 20. The portion of the terminal spring 19 located substantially in the center in the front-rear direction functions as a fulcrum portion 22 in contact with the upwardly raised raised portion 21 provided on the bottom wall 15 of the box portion 12 (see also FIG. 3).

The front end portion (tip portion) of the terminal spring 19 functions as a contact portion 23 that will function as an electrical contact with the tab portion 41 of the male terminal 40. As shown in FIGS. 2 and 3, the contact portion 23 is a portion that is punched upward. Therefore, the upper surface of the contact portion 23 that comes into contact with the tab portion 41 of the male terminal 40 is a curved surface that is curved so as to be convex upward. The tip of the contact 23 extends downward (more accurately, downward and slightly forward), and the tip of the contact 23 has a pointed shape with a constricted tip.

As shown in FIG. 1, a locking piece 24 projecting to one side in the width direction is formed on the side edge of the base end portion 20 of the terminal spring 19. The locking piece 24 is tightly fitted into the locking hole 25 formed over the bottom wall 15 and the side wall 16 on one side in the width direction at the rear end of the box 12, so that the locking piece 24 of the base end 20 of the terminal spring 19 Positioning has been done. As shown in FIG. 1B, the locking piece 24 does not protrude outward (one side in the width direction) from the side wall 16 on one side in the width direction of the box portion 12.

As shown in FIG. 2, in the ceiling wall 17, the region (flat plate region) located above the contact portion 23 of the terminal spring 19 secures the contact pressure between the contact portion 23 and the tab portion 41 of the male terminal 40. It is a pressure receiving unit 27 for this purpose. In the ceiling wall 17, at the rear position of the pressure receiving portion 27, the female housing 30 is locked with a lance 33 (see FIG. 4A) described later, and the female terminal 10 is pulled out from the female housing 30 to the rear. A lance hole 28 is formed to prevent the above.

As shown in FIGS. 1B and 2, in the bottom wall 15, an opening portion 29 having a substantially rectangular shape is formed below the contact portion 23 of the terminal spring 19. When the terminal spring 19 bends and deforms downward due to the insertion of the female terminal 10 of the male terminal 40 into the box portion 12, the tip portion of the contact portion 23 passes through the opening portion 29 downward and the box portion. It protrudes downward from the outer surface (lower surface) of the bottom wall 15 of 12. The female terminal 10 has been described above.

Next, the female housing 30 will be described. As shown in FIG. 4A, the resin female housing 30 is formed with a terminal accommodating chamber 31 for accommodating the female terminal 10. The terminal accommodating chamber 31 penetrates in the front-rear direction, and the front end opening of the terminal accommodating chamber 31 functions as an insertion hole 32 through which the tab portion 41 of the male terminal 40 is inserted. The terminal accommodating chamber 31 is provided with a lance 33 for preventing the female terminal 10 accommodated in the terminal accommodating chamber 31 from coming off rearward so as to face the terminal accommodating chamber 31.

An electric wire W1 crimped by a pair of front and rear crimping pieces 14 is connected to the rear end side of the female terminal 10. The female terminal 10 to which the electric wire W1 is connected is inserted from the rear side of the terminal accommodating chamber 31 to the regular insertion position of the terminal accommodating chamber 31. When the female terminal 10 is inserted to the normal insertion position, the lance 33 engages with the lance hole 28 of the female terminal 10 to prevent the female terminal 10 from coming off rearward.

When the female terminal 10 is accommodated in the regular insertion position of the terminal accommodating chamber 31, as shown in FIG. 4B, the tip of the contact portion 23 of the terminal spring 19 accommodates the terminal via the opening portion 29. It faces the bottom wall 34 that partitions the chamber 31 in the vertical direction. Each member constituting the connector 1 has been described above.

Next, the male terminal 40 and the male housing 50 constituting the mating connector 2 will be described in order.

As shown in FIG. 4A, a rod-shaped tab portion 41 projecting forward is integrally provided at the front end portion of the metal male terminal 40. An electric wire W2 is connected to the rear end side of the male terminal 40. At a predetermined position of the male terminal 40, a lance 53 (see FIG. 4A) described later of the male housing 50 is locked to prevent the male terminal 40 from coming out of the male housing 50 to the rear. A stop 42 is formed.

The resin male housing 50 is formed with a terminal accommodating chamber 51 for accommodating the male terminal 40. The terminal accommodating chamber 51 penetrates in the front-rear direction. The male housing 50 is formed with a bottomed tubular hood portion 52 that opens forward adjacent to the front end of the terminal accommodating chamber 51. The internal space of the hood portion 52 has a shape that can be fitted with the female housing 30. The internal space of the hood portion 52 communicates with the terminal accommodating chamber 51 in the front-rear direction. The terminal accommodating chamber 51 is provided with a lance 53 for preventing the male terminal 40 accommodated in the terminal accommodating chamber 51 from coming off rearward so as to face the terminal accommodating chamber 51.

The male terminal 40 to which the electric wire W2 is connected is inserted from the rear side of the terminal accommodating chamber 51 to the regular insertion position of the terminal accommodating chamber 51. When the male terminal 40 is inserted to the normal insertion position, the lance 53 engages with the locking portion 42 of the male terminal 40 to prevent the male terminal 40 from coming off rearward.

In a state where the male terminal 40 is housed in the regular insertion position of the terminal storage chamber 51, as shown in FIG. 4A, the tab portion 41 of the male terminal 40 is inside the hood portion 52, and the hood portion 52 It protrudes forward from the bottom. Each member constituting the mating connector 2 has been described above.

Next, the fitting of the connector 1 and the mating connector 2 will be described. In order to fit the connector 1 and the mating connector 2, as shown in FIG. 4A, first, the female housing 30 of the connector 1 and the male housing 50 of the mating connector 2 are placed on the front end faces of each other. Are arranged so as to face each other. In this state, as shown in FIG. 4B, the terminal spring 19 of the female terminal 10 is not elastically deformed, so that the tip of the contact portion 23 of the terminal spring 19 is inside the box portion 12 (bottom wall 15). Located above).

Next, as shown in FIG. 5A, the female housing 30 is inserted into the hood portion 52 of the male housing 50. As a result, as shown in FIG. 5B, the tab portion 41 of the male terminal 40 inserts the insertion hole 32 of the female housing 30 and the opening 11 of the female terminal 10 into the pressure receiving portion 27 and the contact portion 23. Enter between. At this time, since the contact portion 23 has a curved surface that is convex toward the male terminal 40, when the male terminal 40 comes into contact with the vicinity of the end surface (for example, a punched surface) of the tip of the contact portion 23. By comparison, the male terminal 40 can be more reliably guided to the regular position in the box portion 12 of the female terminal 10.

As the insertion progresses and as shown in FIG. 6A, when the front end surface of the female housing 30 abuts on the bottom wall of the hood portion 52 of the male housing 50, the female housing 30 (connector 1) and the male housing 50 ( Mating with the mating connector 2) is completed.

In the mating completed state, as shown in FIG. 6B, the lower surface of the tab portion 41 that has entered between the pressure receiving portion 27 and the contact portion 23 presses the upper surface (curved surface) of the contact portion 23 downward. As a result, the terminal spring 19 bends and deforms downward with the fulcrum portion 22 in contact with the raised portion 21 as a fulcrum.

Due to the elastic restoring force of the terminal spring 19 bent and deformed in this way, the tab portion 41 of the male terminal 40 is sandwiched between the contact portion 23 and the pressure receiving portion 27, and the female terminal 10 (electric wire W1) and the male terminal 40 (electric wire W2) is electrically connected.

In the mating completed state, the tip of the contact portion 23 passes downward through the opening portion 29 as shown in FIGS. 6 (b) and 6 (c) due to the downward bending deformation of the terminal spring 19. Then, it projects downward from the outer surface (lower surface) of the bottom wall 15 of the box portion 12 and pierces the inner surface (upper surface) of the bottom wall 34 that partitions the terminal accommodating chamber 31. When the tip of the contact portion 23 pierces the bottom wall 34 in this way, the tip of the contact portion 23 is embedded in the bottom wall 34. That is, the terminal spring 19 has a double-sided beam-like shape. As a result, the contact portion 23 is suppressed from swinging even when an external force such as vibration is applied, and the elastic force exerted by the contact portion 23 on the tab portion 41 is increased. Therefore, the state in which the terminal spring 19 and the tab portion 41 are in contact with each other can be properly maintained.

<Action / effect>
As described above, according to the connector 1 according to the embodiment of the present invention, when the female terminal 10 housed in the female housing 30 of the connector 1 and the male terminal 40 are electrically connected, the terminal spring 19 and the male terminal of the female terminal 10 are connected. The terminal spring 19 is deformed so as to bend in contact with the tab portion 41 of the 40. Then, the tip of the contact portion 23 of the terminal spring 19 comes into contact with the bottom wall 34 of the terminal accommodating chamber 31 through the opening portion 29 provided in the bottom wall 15 of the box portion 12 of the female terminal 10. As a result, the tip of the contact portion 23 of the terminal spring 19 is in contact with the bottom wall 34 of the terminal accommodating chamber 31 as compared with the case where the tip of the terminal spring can be freely displaced as in the conventional connector described above. The displacement of the terminal spring 19 with respect to an external force such as vibration is suppressed. Therefore, the connector 1 can properly maintain the electrical connection between the terminals even when an external force such as vibration is applied in the state where the mating with the mating connector 2 is completed.

Further, according to the connector 1, in the state where the mating with the mating connector 2 is completed, the tip end portion of the contact portion 23 of the terminal spring 19 is embedded in the bottom wall 34 of the terminal accommodating chamber 31 (pierced state). Become. Therefore, the electrical connection between the terminals can be reliably maintained as compared with the case where the tip end portion of the contact portion 23 simply contacts the bottom wall 34. Further, since the terminal spring 19 has a double-sided beam shape, the elastic force exerted by the terminal spring 19 on the tab portion 41 of the male terminal 40 is increased, and the terminal spring 19 and the male terminal 40 are in contact with each other. It can be maintained more properly.

Further, according to the connector 1, the upper surface of the contact portion 23 that comes into contact with the tab portion 41 of the terminal spring 19 is a curved surface that is curved so as to be convex upward. As a result, the upper surface of the contact portion 23 can reliably guide the tab portion 41 of the male terminal 40 at the normal position (between the contact portion 23 and the pressure receiving portion 27), and the tab portion 41 mistakenly guides the tab portion 41 to the contact portion 23 and the bottom wall. It is possible to suppress the entry between the 15 and the like.

<Other forms>
The present invention is not limited to each of the above embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

In the above embodiment, when the fitting is completed, the tip of the contact portion 23 of the terminal spring 19 is pierced into the bottom wall 34 of the terminal accommodating chamber 31 so that the terminal spring 19 is embedded in the bottom wall 34. On the other hand, as shown in FIG. 7, a recess 35 is formed in the bottom wall 34, and the tip of the contact portion 23 of the terminal spring 19 is press-fitted into the recess 35 of the bottom wall 34 in the fitting completed state. Then, it may be configured so as to be embedded in the bottom wall 34. As a result, as compared with the above embodiment in which the tip of the contact portion 23 of the terminal spring 19 is forcibly pierced into the bottom wall 34 having no recess 35, the tip of the contact portion 23 of the terminal spring 19 can be more easily inserted into the terminal accommodating chamber 31. It can be embedded in the bottom wall 34. Therefore, the insertion force (and by extension, the fitting force between the connectors 1 and 2) when the male terminal 40 is inserted into the female terminal 10 can be reduced, and the connector 1 can be easily fitted to the mating connector 2. ..

Further, in the mating completed state, the tip end portion of the contact portion 23 may be in pressure contact with the bottom wall 34 without sticking to the bottom wall 34 of the terminal accommodating chamber 31 (without being embedded in the bottom wall 34). Even with this, compared to the case where the tip of the contact portion 23 does not contact the bottom wall 34 (when the tip of the terminal spring 19 can be freely displaced), vibration is caused by the frictional force generated at the contact portion. The displacement of the terminal spring 19 with respect to an external force such as the above can be suppressed. In this case, the tip of the contact portion 23 does not have to have a sharp shape and can be a flat surface.

Further, in the above embodiment, the tip end portion of the contact portion 23 of the terminal spring 19 comes into contact with (specifically, embedded) the bottom wall 34 of the terminal accommodating chamber 31. However, it is not always the tip of the contact portion 23 that comes into contact with the bottom wall 34 of the terminal accommodating chamber 31, and from the viewpoint of suppressing the swinging movement of the terminal spring 19 due to an external force or the like among the terminal springs 19. An appropriate location may come into contact with the bottom wall 34 of the terminal accommodating chamber 31. That is, at least a part of the terminal spring 19 may function as a contact portion that contacts the bottom wall 34 of the terminal accommodating chamber 31.
