Description

  The present invention relates to an electrical connector having a lock mechanism.

As an electrical connector, a first connector mounted on a circuit board such as a printed wiring board, and a second connector provided at an end of the electric wire and detachably attached to the first connector are provided. There are electrical connectors.
As this type of electrical connector, there is a so-called vertical fitting type (top entry type) in which the second connector is mounted from a direction orthogonal to the mounting surface of the circuit board (see, for example, Patent Document 1).

There is also a so-called lateral fitting type (side entry type) in which the second connector is mounted from a direction parallel to the circuit board (see, for example, Patent Documents 2 and 3).
JP 2000-123912 A JP 2005-26156 A JP 2003-217739 A

In the vertical fitting type electrical connector, it is necessary to secure the stroke amount for fitting both connectors in the direction perpendicular to the mounting surface, so the height of both connectors in the fitted state should be reduced. Is difficult. That is, it is difficult to reduce the height.
In general, the lock arm of the strong lock mechanism extends along the fitting direction of both connectors, and the lock arm supported by the housing of the connector swings its force point, fulcrum, and action point in this order. It is arranged. For this reason, there exists a problem that a lock arm becomes long regarding the fitting direction of both connectors, and, as a result, an electrical connector enlarges.

In the vertical fitting type electrical connector, when the lock arm of the strong locking mechanism as described above is adopted, the height of the electrical connector is remarkably increased.
Further, in the case of a vertical fitting type electrical connector, when the holding force of both connectors is obtained by friction fitting between the housings of both connectors (that is, in the case of friction lock), the second connector is connected to the second connector. There is a problem that the load on the circuit board increases when the connector is attached to one connector. In addition, the friction lock may be unlocked or loosened when subjected to an impact or the like, and there is a problem in terms of reliability.

On the other hand, in the lateral fitting type, since the second connector is stroked in parallel with the circuit board, the substantial occupied area of the electrical connector on the circuit board is widened.
An object of the present invention is to provide an electrical connector that is highly reliable with respect to impact and the like and has a low height.

  In order to achieve the above object, the present invention includes a first connector fixed on a mounting surface and a second connector provided at an end of an electric wire, and the first connector includes the mounting surface. A first housing that defines an insertion recess that opens in a direction in which the connector is pulled out orthogonally, a plurality of first contacts that are held in the insertion recess by the first housing, and a first housing that A connector insertion direction that includes a slider slidably held in a lock position and a lock release position along a slide direction parallel to the mounting surface, and wherein the second connector is in a direction opposite to the connector removal direction A second housing inserted into the insertion recess along the second housing, and a second contact held by the second housing and connected to the first contact. The slider engages with a predetermined portion of the second housing as it slides to the lock position, thereby preventing the second housing from being pulled out from the insertion recess in the connector pull-out direction, and moving the slider to the lock release position. It includes a lock portion that allows the second housing to be removed from the insertion recess in the connector removal direction by releasing the engagement of the second housing with the predetermined portion along with the slide. Is.

  In the present invention, so-called vertical fitting is used, but since it is not a friction lock, a load on, for example, a circuit board as a mounting surface is small. In addition, since a strong lock is adopted, the lock will not be released even when subjected to an impact or the like, and the reliability is high. Moreover, since the lock part for the strong lock is provided in the slider which slides in a direction parallel to the mounting surface, the height of the electrical connector can be reduced.

  The first housing includes a pair of opposing side walls, and the slider extends in a direction orthogonal to the main body from both ends of the main body and along the corresponding side walls of the first housing. And a pair of slidable elastic arms (claim 2). In this case, since the elastic arm of the slider is disposed on the side wall of the second housing, the height of the first connector can be reduced.

The predetermined portion of the first housing includes protrusions provided on a pair of side walls of the first housing, and the lock portion is provided on each elastic arm and is associated with a corresponding protrusion as the predetermined portion. In some cases, the projection includes a matable projection. In this case, the lock portion of each elastic arm is engaged with the protrusion on the corresponding side wall of the second housing, and the lock is achieved.
A guide plate for guiding the slide of the corresponding elastic arm may be provided on each side wall of the first housing. In this case, the slider can be smoothly slid.

The guide plate may include an upper guide plate that receives a removal load of the second connector via an elastic arm. In this case, it is possible to reliably prevent the second connector from being removed from the first connector.
The guide plate includes a lower guide plate facing the upper guide plate, and a guide groove for guiding the slide of the corresponding elastic arm may be defined between the upper guide plate and the lower guide plate ( Claim 6). In this case, the slider can be guided smoothly.

A guide groove for guiding the slide of the corresponding elastic arm may be defined between the upper guide plate and the mounting surface. In this case, the size of the first housing can be reduced by reducing the height of the first housing.
There may be a case where first and second stoppers each including a protrusion for restricting the slider to the locked position and the unlocked state are provided on each side wall of the first housing. In this case, the slider can be reliably restricted to the first and second positions.

  The first and second stoppers may be arranged with their positions shifted from each other with respect to a direction orthogonal to the sliding direction (claim 9). In this case, when the first housing is injection-molded with synthetic resin, the same side surfaces of the first stopper and the second stopper are punched in the same direction, for example, the sliding direction. Molding is also possible, increasing the degree of freedom in mold design.

  Each elastic arm includes a first engagement protrusion and a second engagement protrusion. The first engagement protrusion engages with the second stopper as the slider slides, thereby disengaging the slider. In some cases, the second engagement protrusion is engaged with the first stopper as the slider slides, thereby restricting the slider to the engagement position. In this case, the slider position can be reliably regulated by the engagement of the stoppers corresponding to the respective engaging protrusions.

The first engagement protrusion may also serve as the lock portion (claim 11). In this case, simplification of the structure can contribute to downsizing.
In some cases, the lock portion is disposed in the connector pull-out direction of the protrusion of the second housing. Thereby, a lock part can be latched by the said protrusion of the 2nd housing, and substantial lock can be achieved.

  The slider has a restricting plate as a lock portion extending in parallel with the mounting surface, and the restricting plate is formed on the upper surface as the predetermined portion of the second housing as the slider is displaced to the lock position. The engagement may prevent the second housing from being removed from the insertion recess (claim 13). In this case, since the second housing is prevented from being pulled out by the restricting plate, more reliable locking can be achieved.

When the second connector 5 is inserted into the insertion concave portion 8 of the first connector 3 along the connector insertion direction Y2, the second convex portion 54 passes through the notch 34 and the concave groove 35 of the side wall main body 31. The protrusion 55 is introduced into the guide groove 16 through the notch 34. The concave groove 35 is opened in the connector removal direction Y1.

  A first stopper 36 is formed on the bottom 16a of the guide groove 16 behind the concave groove 35 (second sliding direction Z2), and behind the first stopper 36 (second sliding direction Z2). A second stopper 37 is formed. Each of the stoppers 36 and 37 includes a protrusion protruding into the guide groove 16. On the bottom 16 a of the guide groove 16, an inclined engaging surface 44 is formed below the second stopper 37.

The first stopper 36 and the second stopper 37 are displaced (offset) from each other with respect to the direction orthogonal to the mounting surface 2a, that is, with respect to the connector removal direction Y1 (or the connector insertion direction Y2). . In the present embodiment, the first stopper 36 is disposed relatively lower, and the second stopper 37 is disposed relatively higher.
The rear surface of the first stopper 36 is formed as an inclined cam surface 36a that is inclined so that its height decreases as it goes rearward of the first housing 9 (second sliding direction Z2). That is, the inclined cam surface 36 a is open toward the rear of the first housing 9 (second sliding direction Z <b> 2) and is visible from the rear of the first housing 9.

Further, the front surface of the second stopper 37 is formed as an inclined engaging surface 37b whose height increases as it goes in the first sliding direction Z1.

  Thus, the first and second stoppers 36 and 37 are displaced from each other with respect to the connector removal direction Y1 (the direction orthogonal to the slide direction Z2), and the first and second stoppers 36 and 37 The rear surface is formed on an inclined cam surface 36a and an inclined engaging surface 37a that both open in the same direction (second sliding direction Z2), so that the first housing 9 is made of synthetic resin. In the case of molding, the rear surfaces of the first and second stoppers 36 and 37 can be molded with a mold that slides in the same direction, which facilitates manufacture.

On the other hand, on the inner surface 15 a of each elastic arm 15 of the slider 7, a first engagement protrusion 38, a second engagement protrusion 39, a third engagement protrusion 40, and a fourth lock as a lock portion are provided. An engagement protrusion 41 and a fifth engagement protrusion 43 are formed.
The first engagement protrusion 38 and the second engagement protrusion 39 are displaced from each other in the direction orthogonal to the mounting surface 2a, that is, in the connector removal direction Y1 (or the connector insertion direction Y2) (offset). Have been). In the present embodiment, the first engagement protrusion 38 is disposed relatively higher, and the second engagement protrusion 39 is disposed relatively lower. Further, the third engagement protrusion 40 is disposed relatively higher, and the fourth engagement protrusion 41 and the fifth engagement protrusion 43 are disposed relatively lower.

  The rear surface of the first engagement protrusion 38 as the lock portion is formed as an inclined engagement surface 38a that is inclined so that its height increases as it goes in the second slide direction Z2. Further, the front surface of the second engagement protrusion 39 is formed as an inclined engagement surface 39a whose height decreases as it goes in the first sliding direction Z1. The front surface of the first engagement protrusion 38 is formed as an inclined cam surface 38b whose height decreases as it goes in the first sliding direction.

Further, when the slider 7 is at the lock position shown in FIG. 8 between the second engagement protrusion 39 and the fourth engagement protrusion 41, the engagement is performed to engage the first stopper 36 formed of the protrusion. A recess 42 is formed. The third engaging protrusion 40 has an inclined surface that engages with the inclined engaging surface 37a of the second stopper 37 when the slider 7 is in the locked position shown in FIG.
The fourth engagement protrusion 41 is formed so as to be continuous below the first engagement protrusion 38 (connector insertion direction Y2). The front surface of the fourth engagement protrusion 41 is formed continuously with the front surface of the first engagement protrusion 38, and is inclined cam surface 41a whose height decreases toward the front (first sliding direction Z1). Is formed. Further, the rear surface of the fourth engagement protrusion 41 is formed as an inclined cam surface 41b whose height decreases toward the rear (second slide direction Z2).

Next, with reference to FIG. 9 which is a schematic view, locking and unlocking of the connectors 3 and 5 in the mounted state by the sliding operation of the slider 7 will be described.
FIGS. 9A and 9B show an engagement / disengagement operation between the upper projections 38 and 40 of the slider 7 and the upper stopper 38 of the guide groove 16. FIGS. 9C to 9F show the engagement / disengagement operation between the lower protrusions 39 and 41 of the slider 7 and the lower stopper 36 and the like of the guide groove 16.

  FIGS. 9A and 9C show a state where the slider 7 is in the unlocked position. At this time, the slider 7 in the unlocking position is such that the first engagement protrusion 38 is retracted from the position above the protrusion 55 of the second connector 5, and the first engagement protrusion 38 and the protrusion 55 The engagement with the retaining engagement surface 55a is released. As a result, the second housing 17 is allowed to be removed from the insertion recess 8 in the connector insertion direction Y2.

Further, as shown in FIG. 9A, the inclined engaging surface 38a on the rear surface of the first engaging protrusion 38 is engaged with the inclined engaging surface 37b on the front surface of the second stopper 37, The movement of the slider 7 in the second sliding direction Z2 is restricted, and the slider 7 is restricted to the unlocking position.
As shown in FIG. 9D, in the middle of the stroke in which the slider 7 is slid along the first sliding direction Z1 from the unlocking position shown in FIG. 7 to the locking position shown in FIG. When the inclined cam surface 41a of the engagement protrusion 41 is engaged with the inclined surface 36a of the first stopper 36, each elastic arm 15 is once expanded outward, and then the fourth engagement. The protrusion 41 gets over the first stopper 36.

  As a result, as shown in FIG. 9E, the slider 7 reaches the lock position, and the first stopper 36 is engaged with the engagement recess 42. That is, the inclined cam surface 41 b of the fourth engagement protrusion 41 engages with the inclined cam surface 36 b of the first stopper 36 and the inclined engagement surface 39 a on the front surface of the second engagement protrusion 39. Engages with the inclined cam surface 41 a of the fourth engagement protrusion 41. Further, the lower fifth engagement protrusion 43 of the base end portion of the elastic arm 15 engages with the inclined engagement surface 44 of the guide groove 16 and, as shown in FIG. The third engagement protrusion 40 at the upper stage of the base end portion of the 15 engages with the inclined engagement surface 37a of the second stopper 37, whereby the slider 7 is restricted to the locked position.

On the other hand, in the locked position, as shown in FIG. 9B, the first engagement protrusion 38 is engaged with the retaining engagement surface 55a as the upper surface of the protrusion 55 of the second connector 5. As a result, the first engagement protrusion 38 functions as a lock portion that restricts the removal of the second housing 17 from the insertion recess 8 in the connector removal direction Y1.
Further, the third engagement protrusion 40 engages with the inclined cam surface 37 a on the rear surface of the second stopper 37. As a result, the movement of the slider 7 in the first sliding direction Z1 is restricted, and the slider 7 is restricted to the lock position.

  During the stroke in which the slider 7 is slid along the second sliding direction Z2 from the locked position to the unlocked position, the slider 7 engages with the front surface 36b of the first stopper 36 as shown in FIG. By the action of the inclined cam surface 41 b of the fourth engaging protrusion 41, each elastic arm 15 is once pushed outward, and then the fourth engaging protrusion 41 moves the first stopper 36. I will get over.

  According to the present embodiment, so-called vertical fitting is used, but since it is not friction lock, the load on the mounting surface 2a of the circuit board 2 is small. In addition, since a strong lock is adopted, the lock will not be released even when subjected to an impact or the like, and the reliability is high. Moreover, since each protrusion as a lock part for the strong lock is provided on the slider 7 that slides in a direction parallel to the mounting surface 2a, the height of the electrical connector 1 can be reduced.

Further, since the elastic arm 15 of the slider 7 is disposed on the side wall 13 of the second housing 17, the height of the first connector 3 can be reduced.
Each side wall 13 of the first housing 17 is provided with an upper guide plate 32 and a lower guide plate 33 for guiding the slide of the corresponding elastic arm 15, and the guide groove 16 between these guide plates 32, 33 is provided. Since the slider 7 is guided, the slider 7 can be smoothly slid.

Moreover, since the upper guide plate 32 receives the removal load of the second connector 5 via the elastic arm 15, the removal of the second connector 5 can be reliably prevented.
In addition, since each side wall 13 of the first housing 17 is provided with a first stopper 36 and a second stopper 37 made of protrusions for restricting the slider 7 to the locked position and the unlocked state, the slider 7 Can be reliably regulated to the first and second positions.

  In particular, since the first stopper 36 and the second stopper 37 are arranged so as to be shifted from each other in the direction orthogonal to the sliding directions Z1 and Z2, there are the following advantages. That is, when the first housing 17 is injection-molded with a synthetic resin, the inclined surface 36a on the rear surface of the first stopper 36 and the inclined cam surface 37a on the rear surface of the second stopper 37 in the molding die 2 in the same direction, which is the sliding direction Z2. Further, in the molding die, the front surface 36b of the first stock 36 and the inclined engaging surface 37b on the front surface of the second stopper 37 can be molded in the same direction as the first sliding direction Z1. Is possible. Therefore, the degree of freedom in mold design is increased.

Further, the inclination direction of the inclined engaging surfaces 37b and 38a that are engaged with each other when unlocking can be inclined in a direction that can prevent the movement of the slider 7 in the second sliding direction Z2. It is possible to achieve reliable retaining.
Further, the first engagement protrusion 38 of each elastic arm 15 is engaged with the second stopper 37 to restrict the slider 7 to the disengagement position, and the second engagement protrusion 39 of each elastic arm 15 is Since the slider 7 is restricted to the engagement position by engaging the first stopper 36, the position of the slider 7 can be reliably regulated.

In addition, since the first engagement protrusion 38 as the lock portion is arranged in the connector removal direction Y1 of the protrusion 55 as the predetermined portion of the second housing 17, the substantial lock can be achieved. Can do.
Further, the first engagement protrusion 38 of the elastic arm 15 engages with a protrusion 55 as a predetermined portion of the second housing 17 of the second connector 5 to prevent the second housing 17 from being pulled out. Since the portion is also used, the simplification of the structure can contribute to the miniaturization of the electrical connector 1. However, apart from the first engaging protrusion 38, the elastic arm 15 may be provided with a protrusion dedicated to the lock portion.

10 and 11 show another embodiment of the present invention. The feature of this embodiment is that it is a lock portion, for example, having a rectangular shape extending in a direction parallel to the elastic arm 15 (corresponding to a direction parallel to the mounting surface 2a) from the upper surface 14a of the main body 14 of the slider 7A. The restriction plate 45 is provided.
The restricting plate 45 is engaged with the upper surface 17a as a predetermined portion of the second housing 17 of the second connector 5 as the slider 7A is displaced from the unlocked position of FIG. 10 to the locked position of FIG. This prevents the second housing 17 from being pulled out from the insertion recess 8 in the connector pulling-out direction Y1.

According to the present embodiment, since the second housing 17 is prevented from being pulled out by the restriction plate 45, more reliable locking can be achieved. However, it is possible to achieve locking only with the restriction plate 45.
The present invention is not limited to the above-described embodiments. For example, in each of the above-described embodiments, as shown in FIG. 12 (a), the upper guide plate 32 and the lower guide plate 33 are interposed. The elastic arm 15 is guided by the formed guide groove 16, but as shown in FIG. 12B, the formed guide plate 33 is abolished and formed between the upper guide plate 32 and the circuit board 2. The elastic arm 15 may be guided by the guide groove 16.

Further, as shown in FIG. 12C, the upper guide plate 32 can be eliminated, or as shown in FIG. 12D, both the upper guide plate 32 and the lower guide plate 33 can be eliminated. .
Further, regarding the layout of the first stopper 36 formed at the bottom of the guide groove 16, the type I disposed at the lower stage of the guide groove 16, the type II disposed at the middle stage of the guide groove 16, and the guide groove 16 Examples include Type III disposed in the upper stage, Type IV disposed in a pair in the upper and lower stages of the guide groove 16, and Type V disposed over the entire width of the guide groove 16 from the upper stage to the lower stage.

  Further, regarding the layout of the second stopper 37 formed at the bottom of the guide groove 16, the type a disposed at the upper stage of the guide groove 16, the type b disposed at the middle stage of the guide groove 16, and the guide groove 16. Examples include a type c in which a pair is disposed at the upper and lower stages, a type d that is disposed at the lower stage of the guide groove 16, and a type e that is disposed across the entire width from the upper stage to the lower stage of the guide groove 16.
