Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and in particular to a plug-in structure and device for EDP testing. Background Technology
[0002] With the development and iteration of display technology, large-size and full-screen laptops are the current mainstream trend.
[0003] During the EDP (Embedded DisplayPort) testing phase, tests are conducted by connecting the connectors to the interfaces on the PCB of the LCD module. Currently, to improve the screen-to-body ratio, the PCB of the laptop's LCD module needs to be folded to the back of the panel. Furthermore, to facilitate subsequent assembly, the orientation of the connector interfaces on the PCB is reversed compared to traditional solutions before folding. This changes the connection direction during testing, and using the connectors in the reverse direction can easily obstruct the panel, affecting optical inspection of the panel. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides a plug-in structure and apparatus for EDP testing.
[0005] In a first aspect, this application provides a plug-in structure for EDP testing, comprising:
[0006] Terminal assembly, including terminals for mating with a connector for a PCB and wires for connecting the terminals;
[0007] The base has a front and a back facing each other. The back of the base is provided with a groove for accommodating the wire, and the wire is led out from one side of the base in the left-right direction.
[0008] The terminal is disposed at the front end of the base in the insertion direction and located on the back of the base, and the insertion direction is perpendicular to the left-right direction.
[0009] In some embodiments, the base includes a first part and a second part arranged sequentially along the insertion direction, the thickness of the first part being greater than the thickness of the second part, the terminal being disposed on the first part, and the electrical plug of the terminal, which is electrically connected to the connector, extending out of the first part.
[0010] In some embodiments, the base further includes a third part with a thickness greater than that of the first part, the third part being located behind the first part in the insertion direction, and the third part having the groove.
[0011] In some embodiments, the wire groove has a first groove and a second groove that are connected to each other, the first groove extending along the insertion direction and the second groove extending along the left-right direction of the base.
[0012] In some embodiments, the first part is provided with positioning posts on both sides of the base in the left-right direction, the terminal abuts against the positioning posts in the insertion direction, and the terminal is disposed between the two positioning posts;
[0013] And / or, the base is provided with a positioning hole for positioning the position of the base, the positioning hole passing through the first part and the second part.
[0014] In some embodiments, a magnet is also included, which is disposed on the base and located on the back of the base, and the magnet is used to attract the placement platform to position the base.
[0015] In some embodiments, a binding element is also included;
[0016] The base is provided with a groove that connects to the wire channel. The groove extends along the left and right direction of the base, and the base is provided with through holes at both ends of the groove. The binding member passes through the two through holes to bind the wire.
[0017] In some embodiments, the wire is bonded to the base.
[0018] In some embodiments, the length of the base is 24.0mm-24.5mm in the insertion direction.
[0019] Secondly, this application provides an apparatus for EDP testing, including a clamping structure and a plugging structure for EDP testing provided in the first aspect. The clamping structure is used to clamp the base and move it first in a direction opposite to the plugging direction, and then move it in the plugging direction, so that the terminal is plugged into the connector.
[0020] The technical solution provided in this application has the following advantages compared with the prior art:
[0021] The plug structure for EDP testing, by setting a base and terminal assembly, with the terminal located on the back of the base and at the front end of the base in the plugging direction, ensures that the terminal is below the base during plugging. This reduces the overall length of the plug structure in the plugging direction. In addition, with the wire leading out from one side of the base in the left-right direction, the obstruction of the plug structure to the panel in the plugging direction can be reduced or even avoided, thereby reducing the impact on the optical inspection of the panel.

[0033] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0034] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.
[0035] Figure 1 A schematic diagram of the plug-in structure for EDP testing provided in this application embodiment (front of the base). Figure 2 A schematic diagram (reverse side of the base) of the plug-in structure for EDP testing provided in the embodiments of this application. Figure 3 This is a schematic diagram of the terminal assembly described in an embodiment of this application.
[0036] Reference Figures 1 to 3 The aforementioned plug-in structure for the EDP test structure includes a terminal assembly 1 and a base 2.
[0037] The terminal assembly 1 includes terminals 11 for insertion into a connector on a PCB and wires 12 for connecting the terminals 11. The base 2 has opposing front and back sides. A wire groove 21 for accommodating the wires 12 is provided on the back side of the base 2, and the wires 12 extend from one side of the base 2 in the left-right direction. The terminals 11 are located at the front end of the base 2 in the insertion direction and on the back side of the base 2, with the insertion direction perpendicular to the left-right direction.
[0038] The insertion direction is as follows: Figure 2 The X direction indicated by the unidirectional arrow in the middle is reversed, while the left and right directions of base 2 are as follows. Figure 2 The Y direction is indicated by the double-headed arrow. The insertion direction specifically refers to the direction of movement of the base 2 when the terminal 11 is inserted into the connector. The opposite direction is the direction of movement of the base 2 when the terminal 11 is pulled out of the connector.
[0039] Understandably, the plug-in structure for EDP testing, by placing the terminal 11 at the front end of the base 2 in the plug-in direction and on the back of the base 2, helps to shorten the overall length of the plug-in structure in the plug-in direction. The wire 12 is led out from one side of the base 2 in the left-right direction, which avoids the wire 12 from blocking the panel when it is led out from the rear end of the base 2 in the plug-in direction. Thus, when the terminal 11 and the connector are plugged in, the obstruction of the plug-in structure on the panel can be reduced or even eliminated, thereby improving the problem of affecting the optical inspection of the panel.
[0040] In some embodiments, the length of the base 2 in the insertion direction is 24.0mm-24.5mm. Compared with the connectors in the prior art, the overall length is shortened by about 12mm, which can effectively reduce or even avoid the base 2 obstructing the panel when the terminal 11 is inserted into the connector. Of course, the length of the base 2 in the insertion direction can be set according to actual needs.
[0041] Furthermore, the width of base 2 in the left-right direction is 28mm-29mm. Of course, the width of base 2 in the left-right direction can also be set according to actual needs.
[0042] Figure 4 This is a schematic diagram of the structure of the base provided in an embodiment of this application. Figure 5 This is a bottom view of the base provided in an embodiment of this application. Figure 6 for Figure 5 Schematic sectional view along the AA direction.
[0043] Reference Figures 4 to 6 The base 2 includes a first part 2a and a second part 2b arranged sequentially along the insertion direction. The thickness of the first part 2a is greater than the thickness of the second part 2b. The terminal 11 is disposed in the first part 2a and the electrical plug 111 of the terminal 11, which is electrically connected to the connector, extends out of the first part 2a.
[0044] Understandably, the first part 2a and the second part 2b form a stepped structure. The electrical connector 111 of the terminal 11 extends out of the first part 2a, and a gap is formed between the electrical connector 111 and the second part 2b. This not only avoids the second part 2b from affecting the insertion of the electrical connector 111 and the connector, but also helps to reduce the length of the base 2 in the insertion direction.
[0045] It should be noted that, in the insertion direction, there is a preset distance between the front end face of the aforementioned electrical connector in the insertion direction and the front end face of the base 2 in the insertion direction. This preset distance is reasonably set so that the length of the base 2 is as small as possible, and the second part 2b does not affect the insertion of the electrical connector 111 and the connector.
[0046] Reference Figure 1 and Figure 4 In some embodiments, the base 2 is provided with a positioning hole 22 for positioning the position of the base 2, and the positioning hole 22 passes through the first part 2a and the second part 2b.
[0047] Understandably, by opening the positioning hole 22, the device used for EDP testing can position the base 2 through the positioning hole 22, thereby positioning the position of the base 2 before the terminal 11 and connector are inserted, ensuring that the terminal 11 and connector are aligned, and thus ensuring that the terminal 11 and connector are subsequently inserted into place.
[0048] Reference Figure 4 In some embodiments, the first part 2a is provided with positioning posts 2d on both sides of the base 2 in the left-right direction, and the terminal 11 abuts against the positioning posts 2d in the insertion direction and is disposed between the two positioning posts 2d.
[0049] Understandably, the positioning post 2d provides positioning and limiting for the installation of terminal 11, improving the accuracy of terminal 11 installation and preventing terminal 11 from tilting and affecting the insertion connection with the connector. Thus, when installing terminal 11, it is inserted between the two positioning posts 2d, and the terminal 11 abuts against the positioning post 2d in the insertion direction, indicating that terminal 11 is installed in place.
[0050] Terminal 11 can be optionally bonded to the base 2 by adhesive, meaning that terminal 11 is fixed to the base 2 with adhesive. In this case, no other additional structure is required, nor is it necessary to process holes or other structures on the base 2, making the operation simple. Of course, terminal 11 can also be fixed to the base 2 with screws, which facilitates the installation and removal of terminal 11.
[0051] Reference Figure 4 In some embodiments, the plug structure for EDP testing also includes a binding member (not shown in the figure). The base 2 is provided with a groove 23 that connects to the wire groove 21. The groove 23 extends in the left and right direction of the base 2, and the base 2 is provided with through holes 24 at both ends of the groove 23. The binding member passes through the two through holes 24 to bind the wire 12.
[0052] Understandably, the aforementioned wire 12 can be secured to the base 2 by a binding member, and the binding member can be accommodated within the groove 23, thereby concealing the binding member. The binding member can be either iron wire or cable ties; no specific limitation is made here.
[0053] Furthermore, the aforementioned groove 23 is located on the back of the base 2 to conceal the binding member on the front of the base 2. The front of the base 2 has a recessed groove 25 extending in the left-right direction of the base 2. The aforementioned two through holes 24 are located at the two ends of the recessed groove 25. Thus, when the binding member binds the wire 12, the binding member passes through the two through holes 24 and is located in the recessed groove 25 on the front of the base 2 and in the groove 23 on the back of the base 2. This prevents the binding member from protruding from the base 2, improving aesthetics and avoiding interference between the binding member and other structures (such as components on the PCB) during the movement of the base 2.
[0054] Reference Figure 4 In some embodiments, the base 2 has two extensions 2e extending outward on both sides in the left-right direction, and the two extensions 2e are spaced apart in the insertion direction. Thus, a clamping opening 26 is formed between the two extensions 2e for the clamping structure (not shown in the figure) to extend into, so that the base 2 has a clamping opening 26 on both sides in the left-right direction. This facilitates positioning and limiting the base 2 through the clamping opening 26 when the clamping structure clamps the base 2, and also enables the clamping structure to stably clamp the base 2.
[0055] It should be noted that the above-mentioned clamping structure clamps the base 2 in the left and right direction and extends into the clamping port 26, so as to stably clamp the base 2 and drive the entire plug-in structure to move.
[0056] Reference Figure 4 and Figure 6 In some embodiments, the base 2 further includes a third part 2c with a thickness greater than that of the first part 2a. The third part 2c is located on the rear side of the first part 2a in the insertion direction, and the third part 2c has a wire groove 21.
[0057] Understandably, the thickness of the third part 2c is set to be greater than the thickness of the first part 2a, so that it is convenient to open a groove 21 in the third part 2c to accommodate the wire 12. If the thickness of the third part 2c is less than the thickness of the first part 2a, opening a groove 21 in the third part 2c may not be able to fully accommodate 12, resulting in the wire 12 being exposed.
[0058] It should be noted that the first part 2a, the second part 2b, and the third part 2c that constitute the base 2 are integrally formed. For example, they can be plastic parts formed by injection molding, or they can be sheet metal parts formed by cutting.
[0059] Reference Figure 4 The aforementioned cable groove 21 has a first groove and a second groove that are connected. The first groove extends along the insertion direction, and the second groove extends along the left and right direction of the base 2. This allows the cable 12 to be led out from the left and right direction of the base 2, thus preventing the cable 12 from blocking the panel in the insertion direction.
[0060] The wire 12 can be bonded to the base 2, in which case the wire 12 is fixed in the wire groove 21 by adhesive, without the need for any other additional structures.
[0061] It should be noted that the depth of the above-mentioned groove 21 can be set to be equal to the thickness difference between the third part 2c and the first part 2a. In this way, the bottom surface of the groove 21 is flush with the back surface of the first part 2a, which facilitates the arrangement of the wire 12 and avoids the sharp corner of the step between the first part 2a and the groove 21 from squeezing the wire 12.
[0062] Reference Figure 5 and Figure 6 In some embodiments, the plug structure for EDP testing also includes a magnet 3, which is disposed on the base 2 and located on the back of the base 2. The magnet 3 is used to attract the placement stage (not shown in the figure) to position the base 2.
[0063] Understandably, by setting the magnet 3, after the terminal 11 is disengaged from the connector, the base 2 can be placed on the placement platform, and the positioning and fixing of the base 2 are achieved by the magnet 3 adsorbing the placement platform. That is to say, the base 2 is normally fixed on the placement platform by the magnet 3 adsorbing it. When testing is required, the clamping structure clamps the base 2, causing the base 2 to detach from the placement platform. At this time, the clamping structure needs to overcome the adsorption force of the magnet 3.
[0064] Reference Figure 5 and Figure 6 The magnet 3 is located in the first part 2a of the base 2, which ensures that the magnet 3 does not extend beyond the third part 2c or extends beyond the third part 2c by a small distance, which helps to reduce the overall thickness of the plug-in structure.
[0065] In addition, there are two magnets 3, and the two magnets 3 are symmetrically arranged on the base 2, so that the base 2 is balanced in the left and right directions, which is conducive to the balance and fixation of the base 2.
[0066] Reference Figures 1 to 6 A plug-in structure for EDP testing is provided, including a terminal assembly 1 and a base 2.
[0067] The terminal assembly 1 includes terminals 11 for insertion into a connector on a PCB and wires 12 for connecting the terminals 11. The base 2 has opposing front and back sides. A wire groove 21 for accommodating the wires 12 is provided on the back side of the base 2, and the wires 12 extend from one side of the base 2 in the left-right direction. The terminals 11 are located at the front end of the base 2 in the insertion direction and on the back side of the base 2, with the insertion direction perpendicular to the left-right direction.
[0068] In the insertion direction, the length of base 2 is 24.0mm-24.5mm.
[0069] The base 2 includes a first part 2a and a second part 2b arranged sequentially along the insertion direction. The thickness of the first part 2a is greater than the thickness of the second part 2b. The terminal 11 is disposed in the first part 2a and the electrical plug 111 of the terminal 11, which is electrically connected to the connector, extends out of the first part 2a.
[0070] The base 2 has a positioning hole 22 for positioning the base 2, which passes through the first part 2a and the second part 2b. The first part 2a has positioning posts 2d on both sides of the base 2 in the left-right direction. The terminal 11 abuts against the positioning posts 2d in the insertion direction and is located between the two positioning posts 2d.
[0071] The base 2 also includes a third part 2c with a thickness greater than that of the first part 2a. The third part 2c is located behind the first part 2a in the insertion direction, and a wire groove 21 is provided in the third part 2c. The wire groove 21 has a first groove and a second groove that are connected to each other. The first groove extends along the insertion direction, and the second groove extends along the left and right direction of the base 2. The wire 12 is selected to be bonded to the base 2 by adhesive. In this way, the wire 12 is fixed in the wire groove 21 by adhesive, without the need for any other additional structures.
[0072] The base 2 has two extensions 2e extending outward on both sides in the left and right directions. The two extensions 2e are spaced apart in the insertion direction, so that a clamping opening 26 is formed between the two extensions 2e for the clamping structure to extend into.
[0073] The plug structure for EDP testing also includes a magnet 3, which is disposed on the first part 2a of the base 2 and located on the back of the base 2. The magnet 3 is used to attract the placement platform to position the base 2.
[0074] This application also provides an apparatus for EDP testing, including a clamping structure (not shown in the figure) and a plug-in structure for EDP testing provided in the above embodiments. The clamping structure is used to clamp the base 2, which moves first in the opposite direction to the plug-in direction and then in the plug-in direction, so that the terminal 11 is plugged into the connector.
[0075] The apparatus for EDP testing also includes a platform (not shown) for supporting the base 2. That is, after the test is completed, the base 2 is placed on the platform and secured by magnets 3 on the base 2.
