Description

Technical Field

[0001] The present application relates to an aging test system for a power connector assembly and a display screen. Background Art

[0002] Patent document with publication number CN116581608A discloses a power connector assembly that can be used in a display screen aging test system, which can ensure the stability of power connection. However, in the patent document, the plugging and separation of the first connector and the second connector of the assembly are performed by directly grasping one of the connectors manually. Such operation requires the operator to exert a relatively large force, so the plugging and separation of the assembly becomes more difficult and also increases the risk of electric shock. In particular, when such a power connector assembly is constructed as a heavy-load and high-current structure for use in a large-scale aging test system, the aforementioned problem will become more prominent. Summary of the invention

[0003] In order to solve at least one of the above problems, the present application proposes an aging test system for a power connector assembly and a display screen.

[0008] a first power connector detachably fixed to the second receiving cavity of the cover and having a first power terminal;

[0009] a second power connector detachably fixed to the base and having a second power terminal;

[0010] a manual actuator mounted to the base and connected to the slide, and configured to:

[0011] When the cover is assembled to the slide, the manual actuator is manually operated to drive the slide to move forward in the first direction by manual force, thereby causing the first power connector to be plugged into the second power connector and the first power terminal to be connected to the second power terminal;

[0012] The manual actuator is manually operated to drive the slide to move in the negative direction of the first direction by manual force, thereby separating the first power connector from the second power connector and separating the first power terminal from the second power terminal.

[0013] In some possible embodiments, the manual actuator is configured such that, when the first power terminal is connected to the second power terminal, if a negative force in the first direction is directly applied to the first power connector, the manual actuator prevents the first power connector from moving in the negative direction of the first direction.

[0032] a first signal connector detachably fixed to the cover and having a first signal terminal;

[0033] a second signal connector detachably fixed to the base and having a second signal terminal;

[0034] When the first power terminal is connected to the second power terminal, the first signal terminal is connected to the second signal terminal;

[0035] When the first power terminal is separated from the second power terminal, the first signal terminal is separated from the second signal terminal.

[0036] In some possible implementations, the first accommodating cavity has a fourth opening facing a third direction, the fourth opening is continuous with the first opening, and the third direction is respectively perpendicular to the first direction and the second direction;

[0073] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described below in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, rather than all the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application. It can be understood that, in the absence of conflict, some technical means of the various embodiments described herein can be replaced or combined with each other.

[0074] In the description of the specification and claims of this application, if there are terms such as "first", "second", etc., they are only used to distinguish the objects described and do not have any order or technical meaning. Therefore, the objects defined as "first", "second", etc. may explicitly or implicitly include one or more of the objects. In addition, "one" or "an" and similar words do not indicate a quantitative limitation, but indicate the existence of at least one.

[0075] Figures 1 to 7The power connector assembly provided by an embodiment of the present application is shown. The power connector assembly is a heavy-duty power connector assembly that can carry a large current. The power connector assembly can be applied to a display screen aging test system. The display screen aging test system includes an aging furnace that can provide an aging test environment and a trolley that can be moved in and out of the aging furnace. A DC power source is arranged in the aging furnace. The trolley is provided with an image generator (Pattern Generator, PG) for providing a point screen signal for the tested display screen and a bearing structure for carrying the tested display screen. A part of the power connector assembly (the second power connector 5 described later) has been pre-set in the aging furnace and connected to the power source, and another part of the power connector assembly (the first power connector 4 described later) has been pre-set on the trolley and connected to the image generator. During operation, multiple tested display screens can be positioned and placed on the bearing structure of the trolley, and each tested display screen can be connected to the image signal generator by using a cable, and then the above two parts of the power connector assembly are plugged into each other, so that the power provided by the power source can be transmitted to the image generator via the power connector assembly, thereby realizing the point screen display of each tested display screen.

[0076] For the convenience of explanation, a first direction DR1, a second direction DR2, and a third direction DR3 that are perpendicular to each other are defined, and the direction indicated by the arrow is defined as a positive direction, and the direction opposite to the arrow direction is defined as a negative direction.

[0077] 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.

[0078] The slide 2 is disposed on the base 1 in a manner capable of reciprocating along the first direction DR1, and has a first accommodating cavity 21, and two guide ribs 22 formed on two opposite inner walls of the first accommodating cavity 21 and extending in the second direction DR2. The first accommodating cavity 21 has a first opening 21a facing the positive direction of the first direction DR1 and a second opening 21b facing the negative direction of the second direction DR2.

[0079] 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 accommodating cavity 31 disposed between the two guide grooves 32. The second accommodating cavity 31 has a third opening 31a facing the positive direction of the first direction DR1. The cover 3 is configured to be assembled to the slide 2 in the positive direction of the second direction DR2 and to be removed from the slide 2 in the negative direction of the second direction DR2 through the cooperation between the guide grooves 32 and the guide ribs 22. When the cover 3 is assembled to the slide 2, the cover 3 and the slide 2 are relatively fixed in the first direction DR1 through the cooperation between the guide grooves 32 and the guide ribs 22, and the first opening 21a and the third opening 31a overlap in the first direction DR1, that is, when viewed along the first direction DR1, the first opening 21a and the third opening 31a overlap each other (for example, partially overlap).

[0080] The first power connector 4 is detachably fixed to the second accommodating cavity 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 can be detachably fixed to the second accommodating cavity 31 of the cover 3 by screws, and the second power connector 5 can be detachably fixed to the base 1 by screws. In this way, when the first power connector 4 or the second power connector 5 is damaged, it only needs to be detached from the cover 3 or the base 1 and replaced with a new one. The cover 3, the base 1 and the slide 2 and other components not only serve as the plug-in and separation tools of the first power connector 4 and the second power connector 5, but also function as components of the connector assembly. In addition, the first power connector 4 and the second power connector 5 and the first signal connector 7 and the second signal connector 8 described later can be standard parts purchased in the market, and the cover 3, the base 1 and the slide 2 and other components can be made of materials with high structural strength.

[0081] The manual actuator is mounted to the base 1 and connected to the slide 2. The manual brake 6 is configured as follows:

[0082] When the cover 3 is assembled to the slide 2, the manual actuator 6 is manually operated to drive the slide 2 to move in the positive direction of the first direction DR1 by manual force, thereby making the first power connector 4 plug into the second power connector 5, and the first power terminal 41 is connected to the second power terminal 51; and,

[0083] By manually operating the manual actuator 6 , the slide 2 is driven to move in the negative direction of the first direction DR1 by manual force, thereby separating the first power connector 4 from the second power connector 5 , and separating the first power terminal 41 from the second power terminal 51 .

[0084] In this way, during the operation, the operator can manually hold the cover 3 with the first power connector 4 installed, and apply a force to the cover 3 to press the slide 2 (that is, toward the positive direction of the third direction DR3) when the two guide grooves 32 of the cover 3 are respectively aligned with the two guide ribs 22 of the slide 2, so that the cover 3 and the slide 2 are assembled together by means of the cooperation between the guide grooves 32 and the guide ribs 22, at which time the first opening 21a and the third opening 31a overlap in the first direction DR1, and the first power connector 4 and the second power connector 5 are opposite to each other in the first direction DR1. Then, the manual actuator 6 is manually operated to drive the slide 2 to move in the positive direction of the first direction DR1 by manual force, so that the first power connector 4 and the second power connector 5 are plugged in, and the first power terminal 41 and the second power terminal 51 are connected, so as to obtain a power transmission path through the second power terminal 51 and the first power terminal 41. In addition, the manual actuator 6 can also be manually operated to utilize reverse manual force to drive the slide 2 to move in the negative direction of the first direction DR1, thereby separating the first power connector 4 from the second power connector 5, and separating the first power terminal 41 from the second power terminal 51, thereby disconnecting the power transmission path.

[0085] In this embodiment, the manual actuator is further configured as follows: when the first power terminal 41 is connected to the second power terminal 51 (such as Figure 5 and Figure 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 DR1. In this way, it helps to maintain the plugging stability of the power connector assembly, and avoids the first power terminal 41 and the second power terminal 51 from accidentally loosening or separating and thus causing sparks in the power-on working state.

[0086] Specifically, the manual actuator includes a mounting seat 63 , a first connecting rod 61 , a second connecting rod 62 and a flip handle 64 .

[0087] The mounting seat 63 has a guide hole 63 a and a limiting surface 63 b that penetrate in the first direction DR1 .

[0088] The first link 61 is inserted into the guide hole 63a and is configured to reciprocate in the first direction DR1 under the guidance of the guide hole 63a. In addition, the first link 61 has a first end 61a connected to the slide 2 and a second end 61b opposite to the first end 61a.

[0089] The second link 62 has a third end 62a and a fourth end 62b opposite to each other, wherein the third end 62a is connected to the second end 61b of the first link 61 in a manner rotatable about the first axis AX1. The first axis AX1 is a virtual axis defined by a pin connecting the second link 62 and the first link 61 and not shown in the figure.

[0090] The flip handle 64 has a gripping portion 641 for the operator to grip, a connecting portion 642 extending from the gripping portion 641, the connecting portion 642 having a fifth end 642a close to the gripping portion 641, a sixth end 642b away from the gripping portion 641, and a limited surface 64a, wherein the fifth end 642a is connected to the aforementioned fourth end 62b of the second connecting rod 62 in a manner that can rotate around the second axis AX2, and the sixth end 642b is connected to the mounting seat 63 in a manner that can rotate around the third axis AX3. In implementation, the aforementioned limited surface 63b of the mounting seat 63 limits the extreme position of the flip handle 64 relative to the mounting seat 63 by contacting the limited surface 64a of the flip handle 64.

[0091] In addition, the first axis AX1, the second axis AX2 and the third axis AX3 all extend along the third direction DR3, and these three axes are all imaginary axes, respectively. Figure 5 The three pins whose reference numerals are omitted are defined in FIG.

[0092] When the flip handle 64 rotates to the aforementioned limit position relative to the mounting seat 63, the flip handle 64 stops rotating because the limiting surface 64a is blocked by the limiting surface 63b. At this time, the first power connector 4 is plugged into the second power connector 5, the first power terminal 41 is connected to the second power terminal 51, and the second axis AX2 is located on the positive side of the imaginary plane PL along the second direction DR2 (in other embodiments, the second axis AX2 extends in the imaginary plane PL), and the imaginary plane PL is a plane defined by the first axis AX1 and the third axis AX3. It can be understood that in this state, if a negative force in the first direction DR1 is directly applied to the first power connector 4, the force will be transmitted to the flip handle 64 and converted into an action to make the flip handle 64 turn in the positive direction. Figure 7 However, the limiting surface 63b of the mounting seat 63 will resist the aforementioned rotational force by supporting the limited surface 64a in the opposite direction, thereby preventing the rotation of the flip handle 64, and thus preventing the first power connector 4 from moving in the negative direction of the first direction DR1, that is, preventing the first power connector 4 from separating 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 separated state, it can usually only be achieved by the operator consciously rotating the flip handle 64 (in the absence of external force, the flip handle 64 can be stabilized in the state by the friction between it and the mounting seat 63). Figure 7 This can prevent the first power terminal 41 and the second power terminal 51 from accidentally loosening or separating, thereby suppressing sparking.

[0093] In this embodiment, the flip handle 64 is spaced a sufficient distance from the slide seat 2 to obtain good electrical isolation, and the length of the gripping portion 641 thereof is greater than the connecting portion 642 , thereby making the operation of the operator more labor-saving.

[0094] The power connector assembly further includes a guide rail 10 , a slider 20 and a handle 30 .

[0095] The guide rail 10 is fixed to the base 1 and extends along the first direction DR1. The slider 20 is fixed to the slide 2 and is slidably connected to the guide rail 10. In this way, the slide 20 and the guide rail 10 that cooperate with each other can guide the slide 2 and thereby guide the first electrical connector to the insertion and separation direction of the second electrical connector, which helps the first electrical connector and the second electrical connector to be smoothly connected and separated.

[0096] The handle 30 is fixed to the cover 3 and is configured to be suitable for applying force in the second direction DR2. With such a design of the handle 30, an operator can easily install the cover 3 with the first power connector 4 installed on the slide 2 along the second direction DR2.

[0097] The power connector assembly also includes a first signal connector 7 and a second signal connector 8. The first signal connector 7 is detachably fixed to the cover 3 via screws, and has a first signal terminal 71. The second signal connector 8 is detachably fixed to the base 1 via screws, 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 can not only transmit electricity of, for example, 220V and heavy-load currents of up to tens of amperes between the aging furnace and the trolley, but also transmit data signals between the two.

[0098] In some embodiments, the first signal terminal 71 and the second signal terminal 72 are pluggable network cable terminals to transmit network signals between the aging furnace and the trolley in a wired manner.

[0099] Furthermore, the first accommodating cavity 21 further has a fourth opening 21c facing the third direction DR3, which is continuous with the first opening 21a. When the cover 3 is assembled to the slide 2, the first signal connector 7 is exposed from the fourth opening 21c. In this way, the first signal connector 7 does not interfere with the assembly of the cover 3 to the slide 2.

[0100] The base 1 also has a third accommodating cavity 11, which has a fifth opening 11a facing the negative direction of the first direction DR1 and a sixth opening 11b facing the negative direction of the second direction DR2, and the second power connector 5 is detachably fixed to the third accommodating cavity 11. The second signal connector 8 is arranged outside the third accommodating cavity 11. In this way, the third accommodating cavity 11 arranged on the base 1 can better protect and position the second power connector 5, and the sixth opening 11b of the third accommodating cavity 11 can be smoothly led out for the cable connected to the second power connector 5.

[0101] Next, see Figures 8 to 9 , Figures 8 to 9 Another embodiment of the present invention provides a power connector assembly having a Figures 1 to 7 For similar structures of power connector components, please refer to the previous Figures 1 to 7 The description of the embodiment shown in the figure is understood, and for the sake of simplicity, the same or similar components are given the same or similar reference numerals, and the repeated detailed description of the same parts is omitted. Figures 1 to 7 The differences between the illustrated embodiments.

[0102] exist Figures 8 to 9 In the illustrated embodiment, the flip handle 64 and the mounting seat 63 are not provided with a limited surface 64a and a limited surface 63b for limiting the extreme position of the flip handle 64, but a first plug hole 61c and a second plug hole 61d are provided on the first connecting rod 61, which are separated from each other in the first direction DR1, and a latch pin 9 included in the manual actuator and an elastic member not shown in the figure are also provided, the first plug hole 61c and the second plug hole 61d both extend in the third direction DR3, and the second plug hole 61d is located on the positive side of the first plug hole 61c along the first direction DR1, Figure 8 and Fig. 9 In the figure, the second plug hole 61d is not visible due to being blocked, but in order to allow the reader to understand the present technology more clearly, a dotted line is used to indicate the position and figure mark of the second plug hole 61d. The plug 9 is mounted to the mounting seat 63 in a manner that it can move along the third direction DR3, and the plug 9 has an insertion position inserted into the first plug hole 61c or the second plug hole 61d and a withdrawal position away from the first plug hole 61c and the second plug hole 61d. The elastic member applies an elastic force along the third direction DR3 to the plug 9 to bias the plug 9 toward the insertion position. The elastic member can be a coil spring connected between the plug 9 and the mounting seat 63.

[0103] In actual application, when 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 socket 61c on the first connecting rod 61 is just at the position of the pin 9, and the pin 9 is automatically inserted into the first socket 61c under the force of the elastic component, so that the first power connector 4 and the second power connector 5 are stabilized in the plugged state. If a negative force in the first direction DR1 is directly applied to the first power connector 4 at this time, the manual actuator, more specifically the plug 9 and the first socket 61c that are plugged into each other will prevent the first power connector 4 from leaving the second power connector 5.

[0104] If the first power connector 4 and the second power connector 5 need to be separated, the operator can pull the latch 9 outward to make the latch 9 overcome the elastic force of the elastic member and leave the first socket 61c, and then rotate the flip handle 64 to move the first connecting rod 61 in the negative direction of the first direction DR1, thereby driving the first power connector 4 to separate from the second power connector 5. In the process of rotating the flip handle 64, since the latch 9 and the first socket 61c are misaligned with each other in the first direction DR1, the operator can release the latch 9 without maintaining the external pulling force on the latch 9. When the rod 61 moves to the position where the second socket 61d thereon is located at the pin 9, the pin 9 is automatically inserted into the second socket 61d under the force of the elastic member, thereby stabilizing the first power connector 4 in a position separated from the second power connector 5. If a positive force in the first direction DR1 is directly applied to the first power connector 4 at this time, the manual actuator, to be more specific, the pin 9 and the second socket 61d that are engaged with each other will prevent the first power connector 4 from moving in the first direction DR1. Thus, accidental movement of the first power connector 4 (slide 2) can be avoided.

[0105] In addition, a pull ring 91 is arranged at the outer end of the latch 9 to facilitate the operator to pull the latch 9 from the insertion position to the removal position.
