Description

The present invention relates to a connector.

Connectors equipped with a housing having a locking mechanism have been proposed. The housing's locking mechanism has a cantilever-shaped locking arm and a release arm connected to the locking arm. The locking arm and release arm are connected by a connecting portion, and an operating portion is provided at the free end of the release arm. When the connector is mated with the mating connector, the locking arm engages with a protrusion on the mating housing that constitutes the mating connector, thereby maintaining the assembled state of the connector and mating connector. In other words, the mated state of the housing and mating housing is maintained. Furthermore, by operating the operating portion of the release arm in the mating release direction, the assembled state of the housing and mating housing is released, and the mated state of the housing and mating housing is released (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2015-195126

In the conventional connector described above, the protective wall of the housing is provided with a curl-prevention protrusion, and the release arm is provided with a locking protrusion. When the connector is handled, such as during transportation, an external force may be applied to the release arm's operating portion due to the wires pulled out of the connector getting caught on the release arm's operating portion, or a surrounding component coming into contact with the release arm's operating portion, causing the release arm's operating portion to lift in the opposite direction to the mating release direction (the direction toward the housing body), causing the release arm to curl up. Even in such cases, the curl-prevention protrusion engages (interferes with) the locking protrusion, preventing the release arm from curling up.

However, if an unintended, excessive external force is applied to the operating portion of the release arm, it is possible that the anti-turning protrusion and the locking protrusion will no longer be able to maintain their engaged (interfering) state due to factors such as deformation of at least one of the anti-turning protrusion and the locking protrusion. If the anti-turning protrusion and the locking protrusion are no longer able to maintain their engaged (interfering) state, stress will concentrate at the connection between the lock arm and the release arm, causing cracks or plastic deformation in the connection, which could impair the original function of the locking mechanism. For example, there is a concern that the locking mechanism may no longer be able to fully perform its function of maintaining the assembled state between the housing and the mating connector when the connector and the mating connector are mated, or its function of releasing the assembled state.

One of the objectives of the present invention is to provide a connector that prevents the function of the locking mechanism from being impaired even if an unintended excessive external force is applied to the locking mechanism.

To achieve the above-mentioned objectives, the connector of the present invention has the following features:

A connector including a housing having a housing main body that is to be assembled to a mating housing along a predetermined assembly direction, and a locking mechanism that can switch between maintaining and releasing the assembled state with the mating housing,
The locking mechanism is
a cantilevered lock arm extending from the housing body toward one side in the assembly direction, and a release arm connected to a tip end of the lock arm and extending along the lock arm toward the other side in the assembly direction,
The release arm
a lock arm having a pivot point portion facing the housing body, an operating portion located on the other side of the pivot point portion in the assembly direction, and a plurality of engaging portions located at different positions in the assembly direction, and configured so that movement of the operating portion in a direction approaching the housing body causes the release arm to pivot around the pivot point portion abutting against the housing body, and movement of the operating portion in a direction away from the housing body is restricted by interference between the plurality of engaging portions and the lock arm or a plurality of turn-up prevention portions of the housing body.
It is a connector.

In the connector of the present invention, when the operating portion of the release arm constituting the locking mechanism moves toward the housing body, the release arm swings around the swing fulcrum portion of the release arm. This swing displaces the locking arm connected to the release arm away from the housing body, releasing the assembled state (i.e., switching between maintaining and releasing the assembled state). In contrast, if an unintended, excessive external force is applied to the operating portion, and the operating portion attempts to move away from the housing body, the multiple engaging portions and the multiple turn-up prevention portions each engage (interfere). This prevents the release arm from moving in that direction (i.e., turning up), and by distributing the external force applied to the operating portion to multiple locations, it is possible to prevent the engagement (interference) between the engaging portion and the turn-up prevention protrusion from being lost even if an excessive external force is applied. Therefore, with a connector of this configuration, the function of the locking mechanism is prevented from being impaired even if an unintended, excessive external force is applied to the locking mechanism.

The present invention has been briefly described above. Furthermore, details of the present invention will become clearer by reading the detailed description of the invention (hereinafter referred to as "embodiments") described below with reference to the accompanying drawings.

<Embodiment>
A connector 2 according to an embodiment of the present invention will be described below with reference to the drawings. When the connector 2 is mated with a mating connector (not shown), the housing 1 is assembled to the mating housing (not shown). For ease of explanation, "front,""rear,""left,""right,""upper," and "lower" are defined below as shown in FIG. 1 and other figures. The "front-rear direction,""left-rightdirection," and "up-down direction" are mutually orthogonal. The front-rear direction coincides with the mating direction between the connector 2 and the mating connector (i.e., the assembly direction between the housing 1 and the mating housing). For each of the connector 2 and the mating connector, the mating direction in the front-rear direction is the front side, and the mating direction in the front-rear direction is the rear side.

As shown in Figures 1 and 2, the connector 2 includes a housing 1, a packing 30 attached to the housing 1, and a front holder 40 attached to the housing 1. The configuration of the connector 2 is described below.

The housing 1 is a molded resin product, and as shown in Figure 2 and elsewhere, comprises a housing main body 10 and a locking mechanism 20, which are integrated into one unit. As shown in Figure 2, the housing main body 10 has a hood portion 11 that is a generally rectangular tube extending in the front-to-rear direction. The top of the hood portion 11 is open in the front-to-rear direction. A terminal accommodating portion 12 extending in the front-to-rear direction is provided integrally with the hood portion 11 within the hood portion 11. An annular recess 13 that opens forward and extends in the front-to-rear direction is defined between the inner peripheral surface of the hood portion 11 and the outer peripheral surface of the terminal accommodating portion 12. The housing 1 and the mating housing are assembled by inserting a tubular assembly portion (not shown) of the mating housing into the annular recess 13.

As shown in Figure 4, the interior of the terminal accommodating section 12 is provided with multiple terminal accommodating chambers 14 that penetrate in the front-to-rear direction and are aligned in the left-to-right and front-to-rear directions. A terminal (female terminal; not shown) connected to the end of the electric wire W is inserted into each terminal accommodating chamber 14 from the rear and accommodated therein. A cantilevered lance 15 that extends diagonally forward and downward toward the interior of the terminal accommodating chamber 14 is integrally provided at a predetermined position on the upper side of the inner wall of each terminal accommodating chamber 14. When the terminal is inserted, the lance 15 temporarily elastically deforms upward, allowing the terminal to be accommodated in the correct position in the terminal accommodating chamber 14. When the terminal is accommodated in the correct position, the lance 15 engages with a portion of the terminal, thereby preventing the terminal from slipping out rearward from the terminal accommodating chamber 14.

A rubber annular gasket 30 is attached to the outer peripheral surface of the terminal accommodating portion 12 at a predetermined position in the front-to-rear direction so that it adheres closely to the outer peripheral surface (see Figure 4, etc.). When the housing 1 is assembled with the mating housing, the gasket 30 adheres closely to the inner peripheral surface of the cylindrical assembly portion of the mating housing that is inserted into the annular recess 13, thereby providing a waterproof function that prevents water from entering or leaving the assembly area.

A resin front holder 40 is attached to the front end of the terminal accommodating section 12 (see Figures 1 and 4). When the front holder 40 is attached to the front end of the terminal accommodating section 12 in the correct position with the terminal accommodated in the terminal chamber 14, as shown in Figure 4, the detection plate 41 of the front holder 40 enters the space adjacent to the upper side of the lance 15 within the terminal accommodating chamber 14. As a result, unintended upward deformation of the lance 15 is prevented. This allows the front holder 40 to maintain engagement between the lance 15 and a portion of the terminal, firmly preventing the terminal from slipping out rearward from the terminal accommodating chamber 14 (a so-called double locking function). On the other hand, when an attempt is made to attach the front holder 40 to the front end of the terminal accommodating section 12 when the terminal is housed in a partially inserted position behind the normal position, the tip of the lance 15, which is elastically deformed upward due to pressure from the terminal, interferes with the detection plate 41, preventing the front holder 40 from being attached to the normal position at the front end of the terminal accommodating section 12. This allows the front holder 40 to function as a detector for detecting partially inserted terminals.

As shown in Figures 2 and 3, a pair of left and right protective walls 16 are integrally formed on the left and right edges of the upper opening of the hood portion 11, extending in the front-to-rear direction, protruding upward and extending in the front-to-rear direction. The pair of protective walls 16 function to protect the locking mechanism 20 located between them. The front ends of the pair of protective walls 16 are connected in the left-to-right direction by a connecting portion 17 that extends in the left-to-right direction.

A pair of first curl-up prevention portions 18 are provided on the left-right inner surfaces of the rear ends of the pair of protective walls 16 (see Figures 2, 3, and 7). In this example, each first curl-up prevention portion 18 is configured as a protrusion that protrudes inward in the left-right direction. The pair of first curl-up prevention portions 18 are arranged so that they can engage with a pair of first engagement portions 26 (described below) in the vertical direction (see Figure 6). The effect of providing the first curl-up prevention portions 18 and first engagement portions 26 in this manner will be described later.

A fixing portion 19 is integrally formed with the lower portion of the hood portion 11 (see Figures 2 and 4, etc.). A recess 19a that opens forward and extends in the fore-and-aft direction is defined between the fixing portion 19 and the lower portion of the hood portion 11 (see Figure 4). When the connector 2 is mounted on a vehicle, a vehicle-side stay (not shown) is inserted into the recess 19a, thereby securing the connector 2 to the vehicle.

The locking mechanism 20 is integrally formed on the upper surface 12a of the terminal accommodating portion 12 (see Figures 5 and 6) and is positioned between a pair of protective walls 16. The locking mechanism 20 has the function of maintaining the assembled state between the housing 1 and the mating housing, and the function of releasing that assembled state.

As shown in Figures 2 to 6, the locking mechanism 20 has a pair of left and right locking arms 21. Each locking arm 21 has a cantilevered shape that extends forward from the upper surface 12a of the terminal accommodating portion 12 and is elastically deformable in the vertical direction (see Figure 5). The front ends (front ends) of the pair of locking arms 21 are connected in the horizontal direction by a locking portion 22 (see Figure 3). The locking portion 22 engages with a locking protrusion (not shown) on the mating housing to maintain the assembled state between the housing 1 and the mating housing. A pair of left and right second curling prevention portions 27 are provided on the outer horizontal surfaces of the pair of locking arms 21 at approximately the center in the front-to-rear direction (see Figures 5 and 7). In this example, each second curling prevention portion 27 is composed of a protrusion that protrudes outward in the horizontal direction. The pair of second curling prevention portions 27 are positioned to be able to engage in the vertical direction with a pair of second engagement portions 28 (described later) (see Figure 5). The effect of providing the second curling prevention portion 27 and second engagement portion 28 will be described later.

A pair of left and right release arms 24 are integrally attached to the tips of the pair of locking arms 21 via a pair of left and right connecting portions 23 (see Figure 3) that protrude outward in the left-right direction from the tips. Each release arm 24 has a cantilever shape that extends rearward from the connecting portion 23 (see Figure 6). The pair of release arms 24 extend along the pair of locking arms 21 on the left-right outer sides of the pair of locking arms 21 (see Figure 3). The tips (rear ends) of the pair of release arms 24 are connected in the left-right direction by an operating portion 25 that extends in the left-right direction (see Figures 2 and 3, etc.).

Each release arm 24 has a downwardly protruding pivot point 24a at a midpoint in the front-rear direction forward of the operating portion 25 (see FIG. 6). In this example, the front-rear position of the pivot point 24a substantially coincides with the front-rear position of the base end 21a of the lock arm 21 (see FIG. 5) (see FIG. 6). A pair of left and right first engagement portions 26 are provided on the outer left-right surfaces of the pair of release arms 24 at a position rearward of the pivot point 24a, corresponding to the pair of first turn-up prevention portions 18 of the housing main body 10 (see FIGS. 6 and 7). In this example, each first engagement portion 26 is configured as a protrusion that protrudes outward in the left-right direction. As shown in FIGS. 6 and 7, when the lock mechanism 20 is in its normal state, the pair of first engagement portions 26 are located below the pair of first turn-up prevention portions 18 and are arranged vertically opposite the pair of first turn-up prevention portions 18 with a small gap between them.

A pair of left and right second engagement portions 28 are provided at the lower end of the inner left-right surfaces of the pair of release arms 24, at positions forward of the swing fulcrum portion 24a, corresponding to the second turn-up prevention portions 27 of the pair of locking arms 21 (see Figures 5 and 7). In this example, each second engagement portion 28 is configured as a protrusion that protrudes inward in the left-right direction. As shown in Figures 5 and 7, when the locking mechanism 20 is in its normal state, the pair of second engagement portions 28 are located below the pair of second turn-up prevention portions 27, and are arranged opposite the pair of second turn-up prevention portions 27 in the vertical direction with a small gap between them. The configuration of the connector 2 has been described above.

Next, we will explain the mating operation between the connector 2 and the mating connector. To mate the connector 2, equipped with the packing 30 and front holder 40, with the mating connector, first position the housing 1 and the mating housing so that they face each other in the front-to-rear direction. Next, bring the housing 1 and the mating housing close to each other so that the cylindrical assembly portion of the mating housing is inserted into the annular recess 13 of the housing 1 and the locking protrusion of the mating housing passes under the locking portion 22 of the housing 1. During this process, the locking portion 22, which has climbed onto the locking protrusion, temporarily moves upward while elastically deforming upward the pair of locking arms 21. Once the locking portion 22 climbs over the locking protrusion, the pair of locking arms 21 elastically return downward, returning the locking portion 22 to its original position. This completes the mating of the connector 2 and the mating connector. In this fully mated state, the locking protrusion and the locking portion 22 engage in the front-to-rear direction, making the connector 2 and the mating connector inseparable, and the fully mated state is maintained. In other words, the assembled state between housing 1 and the mating housing is maintained.

Next, referring to Figures 8 and 9, the operation for separating the fully mated connector 2 from the mating connector will be described. To separate the connector 2 from the mating connector, the operating portion 25 of the locking mechanism 20 of the housing 1 is moved downward (toward the upper surface 12a of the terminal accommodating portion 12) (pressed downward). This causes the swing fulcrum portions 24a of the pair of release arms 24 to abut against the upper surface 12a of the terminal accommodating portion 12, and the pair of release arms 24 swing upward around the swing fulcrum portions 24a (see also the arrows in the figure). In conjunction with this swing of the release arms 24, the pair of locking arms 21 elastically deform upward, causing the locking portion 22 to move upward. This releases the longitudinal engagement between the locking protrusions and the locking portion 22, enabling the connector 2 and the mating connector to be separated. In other words, the assembled state of the housing 1 and the mating housing is released.

At this time, as shown in FIG. 8, the second curl-up prevention portion 27 is provided on the lock arm 21, and the second engagement portion 28 is provided on the release arm 24. As the release arm 24 swings, the lock arm 21 elastically deforms, causing both the second curl-up prevention portion 27 and the second engagement portion 28 to move upward. In other words, the second curl-up prevention portion 27 and the second engagement portion 28 do not engage (interfere) with each other when the assembled state is released. Furthermore, as shown in FIG. 9, the first curl-up prevention portion 18 is fixed to the protective wall 16 of the housing 1 and does not move, so the first engagement portion 26 moves downward, away from the first curl-up prevention portion 18. In other words, the first curl-up prevention portion 18 and the first engagement portion 26 do not engage (interfere) with each other when the assembled state is released.

Next, we will explain the effect of providing the locking mechanism 20 with the first engagement portion 26, first curl-up prevention portion 18, second engagement portion 28, and second curl-up prevention portion 27. When transporting the connector 2 or installing the wires W, for example, if an unintended excessive external force is applied to the operating portion 25 of the release arm 24 of the locking mechanism 20, causing the operating portion 25 to move in a direction away from the upper surface 12a of the terminal accommodating portion 12 (upward, i.e., in the opposite direction from the normal operating direction), as shown in FIG. 10, the second engagement portion 28 of the release arm 24 moves upward and engages (interferes with) the second curl-up prevention portion 27. Furthermore, as shown in FIG. 11, the first engagement portion 26 moves upward and engages (interferes with) the first curl-up prevention portion 18. As a result, further upward deformation (i.e., curling up) of the release arm 24 is restricted.

In this way, if an unintended excessive external force is applied to the operating portion 25 and causes it to move in a direction (upward) away from the upper surface 12a of the terminal accommodating portion 12, the first engagement portion 26 of the release arm 24 engages with the first curl-up prevention portion 18 of the housing main body 10, and the second engagement portion 28 of the release arm 24 engages with the second curl-up prevention portion 27 of the lock arm 21, thereby restricting the operating portion 25 of the release arm 24 from moving in that direction (upward).

As described above, in the connector 2 according to this embodiment, the locking arm 21 constituting the locking mechanism 20 of the housing 1 has a plurality (two) of engaging portions, each consisting of a first engaging portion 26 and a second engaging portion 28, and the release arm 24 has a plurality (two) of turning-over prevention portions, each consisting of a first turning-over prevention portion 18 and a second turning-over prevention portion 27. In other words, the number of engaging portions and turning-over prevention portions is increased compared to conventional connectors. Therefore, even if an unintended excessive external force is applied to the operating portion 25 of the release arm 24, the plurality of engaging portions (the first engaging portion 26 and the second engaging portion 28) engage (interfere) with the plurality of turning-over prevention portions (the first turning-over prevention portion 18 and the second turning-over prevention portion 27), dispersing the external force to multiple locations. This prevents the first engaging portion 26 and the second engaging portion 28 from being unable to maintain their engagement (interference) with the first turning-over prevention portion 18 and the second turning-over prevention portion 27. Therefore, in the connector 2 of this embodiment, the function of the locking mechanism 20 can be maintained even if an unintended excessive external force is applied to the locking mechanism 20.

<Other Aspects>
It should be noted that the present invention is not limited to the above-described 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 embodiments, and modifications, improvements, etc. are possible as appropriate. Furthermore, the material, shape, dimensions, number, location, etc. of each component in the above-described embodiments are arbitrary as long as they can achieve the present invention, and are not limited thereto.

For example, in the above embodiment, the first curl-up prevention portion 18 that engages with the first engagement portion 26 is provided on the housing main body 10, and the second curl-up prevention portion 27 that engages with the second engagement portion 28 is provided on the lock arm 21. Alternatively, the first curl-up prevention portion 18 that engages with the first engagement portion 26 may be provided on the housing main body 10, and the second curl-up prevention portion 27 that engages with the second engagement portion 28 may also be provided on the housing main body 10. In this case, a pair of left and right second curl-up prevention portions 27 that protrude inward in the left-right direction are provided on the inner left-right surfaces of the pair of protective walls 16 forward of the first curl-up prevention portions 18, and a pair of left and right second engagement portions 28 that correspond to the pair of second curl-up prevention portions 27 are provided on the outer left-right surfaces of the pair of release arms 24.

Here, the features of the above-described embodiment of the connector 2 according to the present invention are briefly summarized and listed below in [1] to [4].

[1]
A connector (2) comprising a housing (1) having a housing main body (10) to be assembled to a mating housing along a predetermined assembly direction, and a locking mechanism (20) capable of switching between maintaining and releasing the assembled state with the mating housing,
The locking mechanism (20)
The housing (10) has a cantilever-shaped lock arm (21) extending from the housing main body (10) toward one side in the assembly direction, and a release arm (24) connected to a tip end of the lock arm (21) and extending along the lock arm (21) toward the other side in the assembly direction,
The release arm (24)
The locking arm (21) has a swing fulcrum (24a) facing the housing body (10), an operating part (25) located on the other side of the swing fulcrum (24a) in the assembly direction, and a plurality of engagement parts (26, 28) located at different positions in the assembly direction, and is configured so that movement of the operating part (25) in a direction approaching the housing body (10) swings the release arm (24) around the swing fulcrum (24a) abutting against the housing body (10), and movement of the operating part (25) in a direction away from the housing body (10) is restricted by interference between the plurality of engagement parts (26, 28) and a plurality of turn-up prevention parts (18, 27) of the locking arm (21) or the housing body (10).
Housing (1).

In the connector with the configuration [1] above, when the operating portion of the release arm constituting the locking mechanism moves toward the housing body, the release arm swings around the swing fulcrum of the release arm. This swing displaces the locking arm connected to the release arm away from the housing body, releasing the assembled state (i.e., switching between maintaining and releasing the assembled state). In contrast, if an unintended, excessive external force is applied to the operating portion, and the operating portion attempts to move away from the housing body, the multiple engaging portions and the multiple turn-up prevention portions each engage (interfere). This prevents the release arm from moving in that direction (i.e., turning up), and by distributing the external force applied to the operating portion to multiple locations, it is possible to prevent the engagement (interference) between the engaging portion and the turn-up prevention protrusion from being lost even if an excessive external force is applied. Therefore, with a connector with this configuration, the function of the locking mechanism is prevented from being impaired even if an unintended, excessive external force is applied to the locking mechanism.

In the connector (2) described in the above [1],
The plurality of engaging portions include:
a first engaging portion (26) disposed on the other side of the swing fulcrum portion (24a) in the assembly direction;
a second engaging portion (28) disposed on one side of the swing fulcrum portion (24a) in the assembly direction,
Connector (2).

With the connector having the configuration [2] above, when an external force acting in a direction away from the housing body acts on the operating portion of the release arm, the first engagement portion engages with the turn-up prevention portion on the other side of the swing fulcrum in the assembly direction (i.e., the side closer to the operating portion of the release arm), preventing the release arm from moving in that direction. Furthermore, the second engagement portion engages with the turn-up prevention portion on one side of the swing fulcrum in the assembly direction (i.e., the side closer to the tip of the release arm), preventing the release arm from moving in that direction. This makes it possible to resist unintended, excessive external forces while appropriately dispersing them throughout the entire locking mechanism.

[3]
In the connector (2) described in [2] above,
The plurality of curling prevention portions include:
The housing body (10) has a first curl-up prevention portion (18) that engages with the first engagement portion (26),
The lock arm (21) has a second curl-up prevention portion (27) that engages with the second engagement portion (28).
Connector (2).

In the connector (2) described in [2] above,
The plurality of curling prevention portions include:
The housing body (10) has a first curl-up prevention portion (18) that engages with the first engagement portion (26),
The housing body (10) has a second curl-up prevention portion that engages with the second engagement portion (28).
Connector (2).

The housings configured as described above in [3] and [4] specifically prevent unintended movement of the release arm using the multiple engagement portions and multiple turn-over prevention portions described above.
