Description

  The present invention relates to an electrical connector, and more particularly, to an electrical connector that can be easily and smoothly fitted or detached from one connector with a stable force.

  A power circuit breaker will be described as an example of an electrical connector. The power circuit breaker is used, for example, in an electric vehicle to maintain work safety by opening a circuit of a power source as a battery when maintaining an electric system or the like. As a conventional lever fitting type power circuit breaker, there is one disclosed in Patent Document 1, for example.

  The lever fitting type power circuit breaker disclosed in this document is provided with terminals for making electrical contact and separation by moving the two connector housings close to or away from each other, and the lever is movably movable in one connector housing. The lever is provided with a cam groove, and the other connector housing is provided with a cam pin. Then, the cam groove and the cam pin are engaged. When one connector housing is set to the connector temporary fitting position where the cam pin is engaged with the cam groove with respect to the other connector housing, and the lever is pushed down in this state, the cam pin is guided by the cam groove. The two connector housings move relatively close to each other so that the terminals are in contact with each other. On the other hand, when the lever is pushed up and returned to the original position, the cam pin is guided in the opposite direction by the cam groove, so that the two connector housings move relatively apart, and the terminals are separated from each other and are not in contact with each other. (See Patent Document 1, Claim 1 and FIGS. 10, 11, 16, 17 and the like).

JP 2002-343169 A

  In the power supply circuit breaker described above, the cam pin is guided along the cam groove to convert the acting force due to the vertical movement of the lever into the acting force of the proximity and separation of the two connector housings. Here, the cam groove is not linear but bent. Therefore, for example, in the operation of separating two connector housings, that is, when trying to remove the other connector housing from one connector housing, if the lever is pushed up with a certain force, it may not be able to be removed successfully. It was.

  In other words, there is a place where the cam pin does not slide smoothly while the cam pin slides along the bent cam groove, and if the cam pin comes in that place, the lever must be pushed up with a greater force and a relatively large force. , Can not be removed. In this case, if too much force is applied to the lever in order to remove it, there is a concern that the engagement state between the cam groove and the cam pin is changed, and consequently the engagement state between the two connector housings is also affected. Therefore, it is preferable that the other connector housing can be smoothly removed from one connector housing with a constant force without applying a large force during the removal process. This is true not only for the power supply circuit breaker but also for general electrical connectors.

  Also, in the case of the operation of fitting two connector housings, if the cam pin is moved in the bent cam groove, it is difficult to slide with a stable force, and it is necessary to apply a relatively large force locally. . And since the apparatus of patent document 1 is a structure which a cam pin moves in a cam groove, there was also a possibility that a cam pin or a cam groove might be damaged when a big force was applied to a lever too much at the time of insertion or extraction.

  In view of the above problems, an object of the present invention is to provide an electrical connector that can be easily fitted or detached smoothly from one connector to the other with a stable force.

  In the lever type electrical connector as in the prior art, the cam pin is inevitably guided along the cam groove. In this case, in order to remove the other connector housing from one connector housing, the cam groove is inevitably required. Must be bent. Therefore, this type of electrical connector cannot solve the above problem. Therefore, the present inventors convert the acting force due to the vertical movement of the lever into the acting force of the proximity and separation of the two connector housings with a completely new configuration different from the type in which the cam pin is guided along the cam groove. As a result of intensive studies, it has been found that the following configuration allows the lever to be pushed up or down with a stable force to be smoothly removed or inserted, thereby completing the present invention.

(Embodiment 1)
The electrical connector 100 of this embodiment shown in FIG. 1 has a plug connector 10 (FIG. 2) and a receptacle connector 20 (FIG. 3) as main components.

  As shown in FIG. 2, the plug connector 10 includes a first terminal 11 and a first housing 13 having a convex portion 12 that surrounds the first terminal 11. The first terminal 11 is made of metal, and in FIG. 2, one first terminal 11 is provided in each of two spaces partitioned inside the convex portion 12. The first housing 13 is made of an electrically insulating member and is typically made of resin. When the electrical connector 100 is a power circuit breaker, the fuse 15 is accommodated in the first housing 13 as shown in FIG. The fuse 15 is electrically connected to the first terminal 11.

  As shown in FIG. 3, the receptacle connector 20 accommodates the second terminal 21 and the second terminal 21, and the convex portion 12 is in electrical contact between the first terminal 11 and the second terminal 21. And a second housing 23 having a concave portion 22 that can be fitted with the second housing 23. The second terminals 21 are metal crimp-type contacts. In FIG. 3, two second terminals 21 are provided inside the concave portion 22. The second housing 23 is made of an electrically insulating member and is typically made of resin. When the electrical connector 100 is a power circuit breaker, the cable 26 extends from the second housing 23 as shown in FIG. The cable 26 is electrically connected to the second terminal 21.

  As shown in FIG. 1, the electrical connector 100 is inserted into or removed from the concave portion 22 by inserting or removing the convex portion 12, so that the plug connector 10 is fitted or detached from the receptacle connector 20. The terminals 11 and 21 are electrically contacted or separated. Therefore, the electrical connector 100 can function as a power circuit breaker that shuts off a power circuit (not shown) when the plug connector 10 and the receptacle connector 20 are disconnected.

  The characteristic configuration of the electrical connector 100 of the present embodiment includes a pair of protrusions 30a and 30b shown in FIGS. 1 and 3, a lever 40 shown in FIGS. 1 and 4, and a pair of rotational contacts shown in FIGS. The plug connector 10 can be fitted to or detached from the receptacle connector 20 by the interaction between the members 50 and 50.

  One of the first and second housings 13 and 23, in this embodiment, the second housing 23 on the receptacle connector 20 side, has a pair of projecting portions projecting outward on both side walls 24a and 24b, respectively. 30a, 30b.

  The other of the first and second housings 13 and 23, in this embodiment, the first housing 13 on the plug connector 10 side, includes a lever 40. The lever 40 includes a pair of intermediate support portions 41a and 41b, a pair of operation portions 46a and 46b located on one end side 42 of the intermediate support portion, and a first operation portion located on the other end side 43 of the intermediate support portion. 47. The pair of intermediate support portions 41 a and 41 b are rotatably attached to both side walls 14 a and 14 b of the first housing 13. The pair of operating portions 46a and 46b have first finger pieces 44a and 44b and second finger pieces 45a and 45b which are divided into two portions, and operate in cooperation with the second housing 23. The first operating portion 47 applies a force with the intermediate support portions 41a and 41b as rotation centers when the plug connector 10 is fitted to and detached from the receptacle connector 20. The lever 40 is typically made of resin.

  A pair of rotational contact members 50 and 50 are provided on the distal end side of the first finger pieces 44 a and 44 b of the lever 40. When the plug connector 10 is detached from the receptacle connector 20, the pair of rotary contact members 50 and 50 always maintain contact with the upper end surface 25 while sliding on the upper end surface 25 of the second housing. As can be seen from FIG. 1 (c), the first housing 13 is narrower than the second housing 23, so that the rotating contact member 50 can slide on the upper end surface 25 of the second housing 23. it can. The rotation contact member 50 is typically made of resin.

  The second finger pieces 45a and 45b of the lever 40 come into contact with the operated surfaces 31a and 31b of the projecting portions 30a and 30b of the second housing 23 when the plug connector 10 is fitted to the receptacle connector 20, and the lever operation is performed. It has action surfaces 49a and 49b that transmit the force acting on the portion 47 as a force in a direction in which the plug connector 10 is fitted to the receptacle connector 20. Specifically, the second finger piece 45 has a curved shape so as to cover the protruding portion 30 when fitted, and the second finger piece 45 and the protruding portion 30 slide while the second finger piece 45 is fitted. A force acts in the direction in which the piece 45 pushes the protrusion 30.

  Here, a method for fitting the plug connector 10 to the receptacle connector 20 will be described. From a detached state in which the plug connector 10 is completely separated from the receptacle connector 20, a state in which a part (specifically, a tip portion) of the convex portion 12 of the plug connector 10 is aligned and inserted into the concave portion 22 of the receptacle connector 20. In this specification, it is referred to as “temporary fitting state” and is shown in FIG. When the lever 40 is rotated from the operation start position P1 (FIG. 1 (a)) to the fitting completion position P2 (FIG. 1 (b)) in this temporary fitting state, the working surface 49 of the second finger piece 45 The contact portion of the protrusion 30 with the surface 31 to be acted on is the point of action, and the direction in which the convex portion 12 of the first housing 13 is inserted into the concave portion 22 of the second housing 23, that is, the plug connector 10 and the receptacle connector 20. A force in the direction in which they approach each other acts. As a result, the plug connector 10 is completely inserted into the receptacle connector 20 and becomes “fitted”. In the fitted state, the first and second terminals 11 and 21 are in electrical contact.

  Thus, the electrical connector 100 according to the present invention is fitted by the interaction between the second finger piece 45 of the lever and the protruding portion 50. For this reason, the fitting operation can be performed smoothly with a stable force, rather than moving the cam pin in the cam groove and fitting.

  Next, a method for detaching the plug connector 10 from the receptacle connector 20 will be described. When the lever 40 is rotated back from the fitting completion position P2 to the operation start position P1 in the fitting state (FIG. 1B), the rotation contact member 50 and the upper end face 25 of the second housing 23 are brought into contact with each other. A force in the direction in which the convex portion 12 of the first housing 13 is removed from the concave portion 22 of the second housing 23, that is, the direction in which the plug connector 10 and the receptacle connector 20 are separated from each other, is applied. As a result, the plug connector 10 is separated from the receptacle connector 20. Here, during this separation operation, the rotating contact member 50 always maintains contact with the upper end surface 25 while sliding on the upper end surface 25 of the second housing. That is, the contact portion moves on the upper end surface 25. As described above, since the rotation contact member 50 performs the separation operation while being in contact with and sliding with the upper end surface 25, the plug connector 10 can be reliably and smoothly removed from the receptacle connector 20 with a stable force.

  In this embodiment, as shown in FIG. 5, the rotation contact member 50 has a shape having three protrusions 53a, 53b, 53c extending in different radial directions from the center portion, and two protrusions out of the three protrusions. The end portions of the portions 53b and 53c are in contact with the upper end surface 25 of the second housing. Thus, it is preferable to contact the rotation contact member 50 with the upper end surface 25 at at least two points. When the rotating contact member 50 is in contact with the upper end surface 25 at the side, the friction coefficient between the rotating contact member 50 and the upper end surface 25 is increased, and there is a possibility that smooth sliding cannot be performed. On the other hand, in the point contact where the rotation contact member 50 contacts the upper end surface 25 only at one point, there is a possibility that stable sliding cannot be performed. If the contact is made at least at two points, a smooth and stable slide can be realized. If the rotation contact member 50 has protrusions 53a, 53b, and 53c extending in three directions from the central portion as in the present embodiment, the posture of the rotation contact member 50 when fitted from the detached state. Without considering the above, it is preferable that any two of the three protrusions inevitably come into contact with the upper end surface 25.

  The rotating contact member 50 may have an arcuate shape as shown in FIG. In this case, the both ends 52 a and 52 b of the arcuate rotary contact member 50 are brought into contact with the upper end surface 25 of the second housing 23.

  In the present embodiment, the projecting portion 30 is provided on the second housing 23 as one housing and the lever 40 is provided on the first housing 13 as the other housing. It goes without saying that the case where the first housing 13 and the other housing are the second housing 23 are also included in the present invention.

(Lock mechanism and fitting detection switch mechanism)
The electrical connector of this embodiment is
A locking mechanism for forming a locked state for maintaining the fitted state;
A fitting detection switch that can be turned on only in the locked state; and the first and second terminals are electrically connected only when the fitting detection switch is on.

And the electrical connector of this embodiment is
The lock mechanism includes a first lock portion provided in the one housing, and a second lock portion provided in a first operation portion of the lever and engaged with the first lock portion, and the lever When the second locking portion provided in the first operating portion of the lever is engaged with the first locking portion, the locked state is established.
The fitting detection switch includes a first detection part provided in the one housing and a second detection part provided in the first operation part of the lever and forming an electrical contact with the first detection part. When the lever is rotated to the fitting completion position, the second detection unit provided in the first operation unit of the lever presses or contacts the first detection unit, thereby forming the electrical contact. Then, the fitting detection switch is turned on.

  First, a lock mechanism for forming a lock state for maintaining the fitted state and a method for achieving this lock state in the present embodiment will be described. The lock mechanism includes a first lock portion 71 (FIG. 3) provided in the second housing 23 and a second lock portion 705 provided in the first operation portion 47 of the lever 40. The second lock portion 705 is configured to be engageable with the first lock portion 71. Therefore, when the lever 40 is rotated to the fitting completion position P2, the second lock portion 705 provided in the first operation portion 47 of the lever 40 is engaged with the first lock portion 71, so that the lock described above is performed. It becomes a state. As an example of such an embodiment, in this embodiment, as shown in FIG. 3, the first lock portion 71 is a claw member protruding from the upper surface side of the second housing 23, and the claw member is bifurcated. Each of the divided tips has first and second claws 701 and 702 having thick portions 703 and 704. The second lock portion 705 is a first through hole provided in the first operation portion 47 of the lever 40. Then, as shown in FIGS. 1A to 1B, when the lever 40 is rotated to the fitting completion position P2, the claw member 71 is fitted into the first through hole 705, and the first The second claws 701 and 702 press against the inner wall of the first through-hole 705, and the thick portions 703 and 704 protrude from the upper surface of the lever 40 to fix the lever 40, thereby rotating the lever 40 in the reverse direction. A locked state is formed by suppressing. Thus, in this embodiment, the claw member is provided on the receptacle connector 20 side, the lever is lowered to the mating completion position, the mating state is formed, and at the same time, the locked state is realized.

  Next, a fitting detection switch that can be turned on only in the locked state and a method for achieving the on state of the fitting detection switch will be described. In the present embodiment, the first and second terminals 11 and 21 are electrically connected only when the fitting detection switch is on. For this reason, in the case of the power circuit breaker, the circuit is closed only when the fitting detection switch is on.

  The fitting detection switch includes a first detection unit 81 (FIG. 3) provided in the second housing 23 and a second detection unit 80 (FIGS. 1 and 6) provided in the first operation unit 47 of the lever 40. Composed. The second detection unit 80 forms an electrical contact with the first detection unit 81. Therefore, after rotating the lever 40 to the fitting completion position P2, the second detection unit 80 provided in the first operation unit 47 of the lever 40 presses or contacts the first detection unit 81, so that the electrical contact And the fitting detection switch is turned on. As an example of such an embodiment, in the present embodiment, as shown in FIGS. 1 and 3, the first detection unit 81 has a configuration in which a fourth terminal 803 is disposed in the recess. Moreover, the 2nd detection part 80 is a switching member which has the 3rd terminal 801, as shown in FIG.1 and FIG.6, and it can slide to the 2nd hole 802 provided in the operation part 47 of the lever 40. FIG. It is attached. Therefore, as shown in FIGS. 1 (b) to 1 (c), the switching member 80 is slid from the initial position (position of FIG. 1 (b)) to the pushed-in position (position of FIG. 1 (c)) in the locked state. By doing so, the switching member 80 is inserted into the recess constituting the first detection unit 81. As a result, the third terminal 801 comes into contact with the fourth terminal 803, and the fitting detection switch is turned on. The third terminal 801 and the fourth terminal 803 are typically made of metal. The main body of the switching member 80 is typically made of resin.
