It is to be understood that some of the technical means of the various embodiments described herein may be interchanged or combined without conflict.
In the description of the present specification and claims, the terms "first," "second," and the like, if any, are used merely to distinguish between the described objects and do not have any sequential or technical meaning. Thus, an object defining "first," "second," etc. may explicitly or implicitly include one or more such objects. Also, the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one.
Fig. 1 to 7 show a power connector assembly according to an embodiment of the present application, which is a heavy-duty power connector assembly capable of carrying a large current, and which can be applied to a display burn-in test system including a burn-in oven capable of providing a burn-in test environment and a cart capable of being moved in and out of the burn-in oven, a dc power source being provided in the burn-in oven, an image generator (Pattern Generator, PG) for providing a dot screen signal to a display under test being provided on the cart, and a carrying structure for carrying the display under test being provided on the cart, a part of the power connector assembly (a second power connector 5 described later) having been previously provided in the burn-in oven and having been connected to the power source, and another part of the power connector assembly (a first power connector 4 described later) having been previously provided on the cart and having been connected to the image generator. When in operation, a plurality of tested display screens can be positioned and placed on the bearing structure of the trolley, each tested display screen is connected to the image signal generator by using a cable, and then the two parts of the power connector assembly are mutually spliced, so that the power provided by the power source can be transmitted to the image generator through the power connector assembly, and further the point screen display of each tested display screen is realized.
For convenience of explanation, the first direction DR1, the second direction DR2, and the third direction DR3 are defined to be perpendicular to each other, and the direction indicated by the arrow is defined as positive direction, and the direction opposite to the arrow direction is defined as negative direction.
The power connector assembly comprises a base 1, a slide 2, a cover 3, a first power connector 4, a second power connector 5 and a manual actuator.
The slider 2 is provided on the base 1 so as to be reciprocally movable in the first direction DR1, and has a first accommodation chamber 21, and two guide ribs 22 formed on opposite inner walls of the first accommodation chamber 21 and extending in the second direction DR 2. The first accommodation chamber 21 has a first opening 21a in a positive direction toward the first direction DR1 and a second opening 21b in a negative direction toward the second direction DR 2.
The cover 3 has two guide grooves 32 formed on opposite sides of the cover 3 and extending in the second direction DR2, and a second accommodation chamber 31 disposed between the two guide grooves 32. The second accommodation chamber 31 has a third opening 31a facing the forward direction of the first direction DR 1. The cover 3 is configured to be able to be fitted to the slider 2 in the positive direction of the second direction DR2 and to be separated from the slider 2 in the negative direction of the second direction DR2 by the engagement of the guide groove 32 with the guide rib 22. Wherein, when the cover 3 is assembled to the slider 2, the cover 3 and the slider 2 are relatively fixed in the first direction DR1 by the engagement of the guide groove 32 and the guide rib 22, and the first opening 21a and the third opening 31a overlap in the first direction DR1, that is, the first opening 21a and the third opening 31a overlap (e.g., partially overlap) each other as viewed in the first direction DR 1.
The first power connector 4 is detachably fixed to the second accommodation chamber 31 of the cover 3, and has a first power terminal 41. The second power connector 5 is detachably fixed to the base 1, and has a second power terminal 51. In some embodiments, the first power connector 4 may be detachably fixed to the second receiving cavity 31 of the cover 3 using a screw, and the second power connector 5 may be detachably fixed to the base 1 using a screw. In this way, when the first power connector 4 or the second power connector 5 is damaged, it is only necessary to detach and replace it from the cover 3 or the base 1, and the cover 3, the base 1, the slider 2, and other components function as both the insertion and separation tool of the first power connector 4 and the second power connector 5 and as an integral part of the connector assembly. Further, the first and second power connectors 4 and 5 and the first and second signal connectors 7 and 8 described later may be standard parts purchased in the market, and the cover 3, the base 1, the slider 2, and the like may be made of a material having high structural strength.
A manual actuator is mounted to the base 1 and connected to the carriage 2, the manual actuator 6 being configured to:
With the cap 3 fitted to the slider 2, the slider 2 is driven to move in the forward direction of the first direction DR1 by manual force by manually operating the manual actuator 6, and thereby the first power connector 4 is brought into engagement with the second power connector 5, the first power terminal 41 is brought into engagement with the second power terminal 51, and
By manually operating the manual actuator 6, the slider 2 is driven to move in the negative direction of the first direction DR1 by the manual force, and thereby the first power connector 4 is separated from the second power connector 5, and the first power terminal 41 is separated from the second power terminal 51.
In this way, during the operation, the operator can manually hold the cover 3 to which the first power connector 4 has been attached, and apply a force to the cover 3 that presses against (i.e., toward the forward direction of the third direction DR 3) the slider 2 with the two guide grooves 32 of the cover 3 aligned with the two guide ribs 22 of the slider 2, respectively, so that the cover 3 and the slider 2 are assembled together by the cooperation of the guide grooves 32 and the guide ribs 22, with the first opening 21a and the third opening 31a overlapping in the first direction DR1, and the first power connector 4 and the second power connector 5 opposing each other in the first direction DR 1. Then, the manual actuator 6 is manually operated to drive the forward movement of the slider 2 in the first direction DR1 with a manual force, and thereby the first power connector 4 is plugged into the second power connector 5, and the first power terminal 41 is brought into contact with the second power terminal 51, thereby obtaining a power transmission path via the second power terminal 51 and the first power terminal 41. In addition, the manual actuator 6 may also be manually operated to drive the slider 2 to move in the negative direction of the first direction DR1 with a reverse manual force, and thereby separate the first power connector 4 from the second power connector 5, the first power terminal 41 from the second power terminal 51, and disconnect the power transmission path.
Also in the present embodiment, the manual actuator is further configured such that, in a case where the first power terminal 41 is in contact with the second power terminal 51 (as in fig. 5 and 6), if a negative force in the first direction DR1 is directly applied to the first power connector 4, the manual actuator prevents the first power connector 4 from moving in the negative direction of the first direction DR 1. In this way, it is possible to help maintain the stability of the insertion of the power connector assembly, and to avoid the occurrence of a spark phenomenon caused by the first power terminal 41 being accidentally loosened or separated from the second power terminal 51 in the energized operation state.
Specifically, the manual actuator includes a mount 63, a first link 61, a second link 62, and a flip handle 64.
The mount 63 has a guide hole 63a and a stopper surface 63b penetrating in the first direction DR 1.
The first link 61 is penetrated in the guide hole 63a and configured to reciprocate in the first direction DR1 under the guide of the guide hole 63 a. In addition, the first link 61 has a first end 61a connected to the slider 2 and a second end 61b opposite to the first end 61 a.
The second link 62 has a third end 62a and a fourth end 62b disposed opposite to each other, wherein the third end 62a is rotatably connected to the second end 61b of the first link 61 about the first axis AX 1. The first axis AX1 is a virtual axis, and is defined by a pin, not shown, connecting the second link 62 and the first link 61.
The flip handle 64 has a grip 641 to be gripped by an operator, a connecting portion 642 extending from the grip 641, the connecting portion 642 having a fifth end 642a near the grip 641, a sixth end 642b distant from the grip 641, and a restrained surface 64a, wherein the fifth end 642a is rotatably connected to the aforementioned fourth end 62b of the second link 62 about the second axis AX2, and the sixth end 642b is rotatably connected to the mount 63 about the third axis AX 3. In practice, the limiting surface 63b of the mounting base 63 contacts the limited surface 64a of the flip handle 64 to limit the rotational limit position of the flip handle 64 with respect to the mounting base 63.
In addition, the first axis AX1, the second axis AX2, and the third axis AX3 extend in the third direction DR3, and these three axes are virtual axes, and are defined by three pins, each of which is omitted from fig. 5.
When the flip handle 64 is rotated to the aforementioned limit position with respect to the mount 63, the flip handle 64 stops rotating due to the blocked surface 64a being blocked by the blocking surface 63b, at which time the first power connector 4 is plugged into the second power connector 5, the first power terminal 41 is brought into contact with the second power terminal 51, and the second axis AX2 is located on the forward side of the imaginary plane PL in the second direction DR2 (in other embodiments, the second axis AX2 extends in the imaginary plane PL), which is a plane defined by the first axis AX1 and the third axis AX 3. It will be appreciated that in this state, if a negative force in the first direction DR1 is directly applied to the first power connector 4, the force is transmitted to the flipping handle 64 and converted into a rotational force to rotate the flipping handle 64 clockwise in fig. 7 about the third axis AX3, but the stopper surface 63b of the mount 63 resists the aforementioned rotational force by being supported against the stopper surface 64a, thereby preventing the flipping handle 64 from rotating and thus preventing the first power connector 4 from moving in the negative direction of the first direction DR1, i.e., preventing the first power connector 4 from being separated from the second power connector. Therefore, if the first power connector 4 and the second power connector are switched from the plugged state to the disconnected state, the switching can be normally performed only by intentionally rotating the flip handle 64 by the operator (the flip handle 64 can be stabilized at the position shown in fig. 7 by the frictional force between the flip handle and the mount 63 without the action of external force), so that the unexpected loosening or disconnection of the first power terminal 41 and the second power terminal 51 can be avoided, and the sparking phenomenon can be suppressed.
In the present embodiment, the flip handle 64 is spaced from the slider 2 by a sufficient distance to obtain good electrical isolation, and the gripping portion 641 thereof is longer than the connecting portion 642, thereby making the operation of the operator more labor-saving.
The power connector assembly further includes a guide rail 10, a slider 20, and a handle 30.
The guide rail 10 is fixed to the base 1 and extends in the first direction DR 1. The slider 20 is fixed to the carriage 2 and is slidingly connected to the rail 10. In this way, by means of the slider 20 and the guide rail 10 cooperating with each other, it is possible to guide the slide 2 and thus the direction of insertion and separation of the first electrical connector into and from the second electrical connector, facilitating smooth mating and separation of the first electrical connector from the second electrical connector.
The handle 30 is fixed to the cover 3 and is configured to apply a force in the second direction DR 2. By such a handle 30 design, an operator can easily mount the cover 3 with the first power connector 4 mounted thereto on the slider 2 in the second direction DR 2.
The power connector assembly further comprises a first signal connector 7 and a second signal connector 8. The first signal connector 7 is detachably fixed to the cover 3 via a screw, and has a first signal terminal 71. The second signal connector 8 is detachably fixed to the base 1 via a screw, and has a second signal terminal 72. When the first power terminal 41 is connected to the second power terminal 51, the first signal terminal 71 is also connected to the second signal terminal 72. When the first power terminal 41 is separated from the second power terminal 51, the first signal terminal 71 is also separated from the second signal terminal 72. In this way, the power connector assembly is not only capable of transferring power, e.g., 220V, and heavy load currents up to tens of amps between the burn-in oven and the trolley, but is also capable of transferring data signals between the two.
In some embodiments, the first signal terminal 71 and the second signal terminal 72 are pluggable network cable terminals to pass network signals in a wired manner between the burn-in oven and the trolley.
And, the first accommodation chamber 21 further has a fourth opening 21c facing the third direction DR3, the fourth opening 21c being continuous with the aforementioned first opening 21a, and the first signal connector 7 being exposed from the fourth opening 21c when the cover 3 is fitted to the slider 2. In this way, the first signal connector 7 does not interfere with the fitting of the cover 3 to the slide 2.
The base 1 also has a third housing chamber 11, the third housing chamber 11 having a fifth opening 11a facing in a negative direction of the first direction DR1 and a sixth opening 11b facing in a negative direction of the second direction DR2, the second power connector 5 being detachably fixed to the third housing chamber 11. The second signal connector 8 is arranged outside the third accommodation chamber 11. In this way, the third accommodation chamber 11 provided on the base 1 can better protect and position the second power connector 5, and the sixth opening 11b of the third accommodation chamber 11 can smoothly lead out the cable connected to the second power connector 5.

Hereinafter, differences between the present embodiment and the embodiment shown in fig. 1 to 7 will be described with emphasis.
In the embodiment shown in fig. 8 to 9, the turn handle 64 and the mount 63 are not provided with the limited surface 64a and the limited surface 63b for limiting the limit position of the turn handle 64, but a first insertion hole 61c and a second insertion hole 61d spaced apart from each other in the first direction DR1 are provided on the first link 61, and a latch 9 included in a manual actuator and an elastic member not shown are also provided, the first insertion hole 61c and the second insertion hole 61d each extending in the third direction DR3, and the second insertion hole 61d being located on the forward side of the first insertion hole 61c in the first direction DR1, and the second insertion hole 61d being invisible due to being blocked in fig. 8 and 9, but for the sake of the reader more clearly understanding the present technique, a broken line lead is used to indicate the position and reference numeral of the second insertion hole 61 d. The plug 9 is mounted to the mount 63 so as to be movable in the third direction DR3, and the plug 9 has an insertion position into which the first insertion hole 61c or the second insertion hole 61d is inserted and a release position from which the first insertion hole 61c and the second insertion hole 61d are released. The elastic member applies an elastic force in the third direction DR3 to the plug pin 9 to bias the plug pin 9 toward the insertion position. The resilient member may be a coil spring connected between the latch 9 and the mounting 63.
In practical use, in the case where the first power connector 4 is plugged into the second power connector 5 and the first power terminal 41 is connected to the second power terminal 51, the first insertion hole 61c on the first link 61 is just at the plug 9, and the plug 9 is automatically inserted into the first insertion hole 61c under the force of the elastic member, so that the first power connector 4 and the second power connector 5 are stabilized in the plugged state, and in case where a negative force in the first direction DR1 is directly applied to the first power connector 4, the manual actuator, in more detail, the plug 9 and the first insertion hole 61c that are plugged into each other may prevent the first power connector 4 from leaving the second power connector 5.
If the first power connector 4 and the second power connector 5 are to be separated, the operator can pull the latch 9 outwards to make the latch 9 separate from the first jack 61c against the elastic force of the elastic member, then rotate the flip handle 64 to make the first link 61 move in the negative direction of the first direction DR1, and further drive the first power connector 4 to separate from the second power connector 5, and during this rotation of the flip handle 64, since the latch 9 and the first jack 61c are dislocated from each other in the first direction DR1, the operator can release the latch 9 without maintaining the external pulling force on the latch 9, and when the second jack 61d on which the first link 61 moves is located at the latch 9, the latch 9 is automatically inserted into the second jack 61d under the force of the elastic member, so that the first power connector 4 is stabilized in the position separated from the second power connector 5, in case that the positive force in the first direction DR1 is directly applied to the first power connector 4, the manual actuator, in more detail, is the mutually inserted 9 and the second jack 61d, can prevent the first power connector 4 from moving in the positive direction DR1, thereby preventing the accidental movement of the first power connector 4 (first slider 2).
In addition, a pull ring 91 is provided at the outer end of the plug 9 to facilitate the operator pulling the plug 9 from the insertion position to the removal position.
