Description

Technology Field

[0001] The present invention relates to a pin block unit for a camera module inspection device, and more specifically, to a pin block unit for a camera module inspection device that can improve the accuracy of inspection by fixing a plurality of wire pins to both sides of a core block, enabling the upper and lower ends of the wire pins to move elastically independently, and separating a portion of the wire pins from both sides of the core block to disperse the impact generated when the upper and lower ends of the wire pins come into contact with a PCB and a connector module, thereby enabling stable electrical characteristic inspection. Background Technology

[0003] In recent years, portable devices such as mobile phones have evolved alongside technological advancements to be used for multi-convergence purposes, extending beyond simple telephone functions to include music, movies, TV, and games. The camera module is considered the most representative component driving this multi-convergence trend. These camera modules are shifting toward high-resolution displays exceeding a certain pixel count, while simultaneously evolving to implement various additional features such as autofocus (AF) and optical zoom.

[0004] Compact Camera Modules (CCMs) are typically applied to various IT devices, including smartphones and portable mobile communication devices. Recently, however, the release of devices equipped with small camera modules is gradually increasing to meet the diverse tastes of consumers.

[0005] Figure 1 is a diagram schematically showing the configuration of a conventional camera module inspection device.

[0006] Referring to FIG. 1, the connector (31) of the camera module is positioned upward and is electrically separated from the main board (12). The sub-board (21) provided in the cover jig (20) performs the function of electrically connecting the connector (31) and the main board (12).

[0007] That is, the sub-board (21) provided in the cover jig (20) includes a first pogo pin (21a) and a second pogo pin (21b) exposed downward, and when the cover jig (20) moves downward and is closely coupled with the guide jig (10), these first and second pogo pins (21a, 21b) are respectively connected to the upper part of the connector (31) mounted on the guide jig (10) and the upper part of the main board (12) provided in the guide jig (10).

[0008] Figure 1 shows the position and electrical connection relationship between the connector (31) of the camera module, the sub-board (21), and the main board (12).

[0009] In a pogo pin jig inspection device for a camera module in which the connector is positioned upward, as shown in FIG. 1, basically at least one main board and one sub-board, or at least two sub-boards and one main board are required.

[0010] Therefore, at least two PCB boards are required, which increases the overall volume of the jig, and if the connector consists of 24 pins, a total of 48 pins are required, which not only increases the cost of pogo pins but also causes the problem of increased noise in signal processing.

[0011] Typically, a conventional pogo pin consists of a pin body, a spring inserted into the pin body, and a contact end coupled to the upper part of the pin body so as to be vertically movable and capable of elastic movement by the spring. Here, the contact end is the part that contacts the measurement terminal to be measured and directly receives the measurement signal.

[0012] As such, conventional pogo pins are composed of multiple parts, such as a pin body, a spring, and a contact end, and have a structure in which contact resistance increases above a certain level.

[0013] Accordingly, conventionally, there is a problem in which noise exceeding a certain level is generated during the process of transmitting electrical signals input or measured from the contact terminal to the sub-substrate through the pin body, and furthermore, the transmission speed of electrical signals, such as measured image signals, slows down beyond a certain level.

[0014] Therefore, conventionally, when performing novel inspections using pogo pins, the aforementioned problems lead to a decrease in inspection accuracy. Prior art literature

[0092] The above measuring pins (500) are formed with the same shape as each other and are arranged to correspond to each other on both sides of the pin block body (200), and can be arranged in the same number as each other.

[0093] The above configurations are explained.

[0094] Pin block body (100)

[0095] Referring to FIGS. 2 to 4, the pin block body (200) according to the present invention comprises a first pin block body (210) in the shape of a square block and a second pin block body (220) formed integrally at the bottom of the first pin block body (210) and formed such that its width gradually narrows along the downward direction.

[0096] The upper part of the first pin block body (210) forms a first width, and the lower part of the second pin block body (220) forms a second width that is narrower than the first width.

[0097] An installation groove (210a) is formed along the front and rear sides at the upper center of the first pin block body (210). The installation groove (210a) forms a first depth.

[0098] An upper elastic body (300) in the shape of a square block is placed in the above-mentioned installation groove (210a).

[0099] The upper elastic body (300) has a certain thickness. The bottom surface of the upper elastic body (300) can be fixed by being adhered to an adhesive layer (not shown) formed in the installation groove (210a).

[0100] Of course, a catch (not shown) may be formed at the bottom of the upper elastic body (300), and this catch may be configured to be fixed by engaging with a catch groove (not shown) formed in the installation groove (210a).

[0101] And the upper elastic body (300) has a thickness greater than the first depth. Accordingly, the upper end of the upper elastic body (300) protrudes above the installation groove (210a).

[0102] Second fixing grooves (212) are formed at intervals along the front and back on both upper sides of the first pin block body (210), bordered by the above-mentioned installation groove (210a).

[0103] In addition, first fixing grooves (211) are formed on both sides of the first pin block body (210) at the same spacing as the second fixing grooves (212).

[0104] Here, the first fixing grooves (211) are formed along the vertical direction, and the second fixing grooves (212) are formed along the horizontal direction. The second fixing grooves (212) are exposed to the installation groove (210a).

[0105] And, the second pin block body (220) is formed integrally at the bottom of the first pin block body (210).

[0106] The width of the second pin block body (220) is formed to gradually narrow along the downward side.

[0107] Inclined surfaces (S) are formed on both sides of the second pin block body (220).

[0108] The second width at the bottom of the second pin block body (220) is formed to be narrower than the first width at the top of the first pin block body (210).

[0109] A support groove (222) is formed at the bottom of the second pin block body (220).

[0110] A lower elastic body (400) in the shape of a square block is disposed in the support groove (222). The upper end of the lower elastic body (400) is fixedly installed by being fitted onto the upper surface of the support groove (222) using a separate adhesive or a fitting structure.

[0111] Here, the lower end of the lower elastic body (400) fixed to the support groove (222) may protrude downward from the lower end of the second pin block body (220).

[0113] Measuring pins (500)

[0114] The measuring pins according to the present invention are installed symmetrically on both sides of the pin block body described above.

[0115] The above-mentioned measuring pins are formed with the same shape. Accordingly, the configuration of a single measuring pin is described below as a representative example.

[0116] The above measuring pins (500) are positioned at corresponding locations along the central axis of the pin block body (200).

[0117] A certain area between the top and bottom of the above measuring pins (500) is fixed to both sides of the pin block body (200).

[0119] Each of the above-mentioned measuring pins (500) includes a vertical body (510) forming a vertical section along the top and bottom, an upper horizontal body (520) formed by bending at the top of the vertical body (510) and supporting at the top of the pin block body (200), an inclined body (530) inclined upward at the end of the upper horizontal body (520), and a lower horizontal body (540) formed by bending at the bottom of the vertical body (510) and supporting at the bottom of the pin block body (200).

[0120] The end of the above inclined body (530) is connected to the connection terminal of the PCB (10).

[0121] The end of the lower horizontal body (540) is connected to the connector (20) of the camera module.

[0122] In addition, a part of the inclined body (530) is elastically supported at the upper corner of the upper elastic body (300).

[0123] The lower horizontal body (540) above is elastically in contact with the lower end of the lower elastic body (400).

[0124] In addition, a lower inclined body (550) is further formed at the bottom of the vertical body (510) and connected to one end of the lower horizontal body (540).

[0125] The vertical body (510) is fixed to both sides of the first pin block body (210).

[0126] The lower inclined body (550) is spaced apart from both sides of the second pin block body (220).

[0127] The upper end of the above measuring pins (500) is elastically supported on both corners of the upper elastic body (300).

[0128] The lower end of the above measuring pins (500) is elastically supported at the lower end of the lower elastic body (400).

[0129] Here, the vertical body (510) is fitted and fixed into the first fixing groove (211) formed on both sides of the first pin block body (210).

[0130] The upper horizontal body (520) is fitted and fixed in the second fixing groove (212) formed at the upper end of the first pin block body (210).

[0131] A part of the lower horizontal body (540) is fitted and fixed into the third fixing groove formed at the bottom of the second pin block body (220).

[0132] A bending section (531) is formed at the top of the above-mentioned inclined body (530) so as to be bent downwardly.

[0133] The bent portion between the top of the inclined body (530) and the bent portion (531) is physically connected to the connection terminal of the PCB (10).

[0134] And the end of the lower horizontal body can be connected to a connector while elastically contacting the bottom of the lower elastic body.

[0136] As described above, the effect predicted through the structure in which the lower inclined body (550) of the measuring pins in the present invention is spaced apart from both sides of the second pin block body (220) is as follows.

[0137] It can maintain stable contact with the camera module connector.

[0138] The connector of the camera module generally contacts the end of the lower horizontal body (540) to transmit an electrical signal.

[0139] As the lower inclined body (550) is separated from the second pin block body (220), the pressure applied to the lower horizontal body (540) when the camera module is inserted is reduced.

[0140] This prevents the lower horizontal body (540) from being excessively compressed or deformed against the connector, thereby allowing stable and continuous contact to be maintained.

[0141] In addition, the present invention may facilitate the insertion and removal of camera modules.

[0142] When inserting or removing the camera module from the pin block unit, the spaced-apart space between the lower inclined body (550) and the second pin block body (220) acts as a kind of clearance.

[0143] The aforementioned clearance helps the camera module connector to smoothly contact and slide with the measurement pins, thereby facilitating the insertion and removal process.

[0144] In particular, even if there is a slight error in the size or shape of the camera module, this clearance enables insertion and removal without interference or damage to the measuring pins.

[0145] In addition, the present invention may improve the durability of the measuring pins.

[0146] By separating the lower inclined body (550) from the second pin block body (220), the lateral pressure or torsional stress applied to the measuring pins when inserting the camera module is reduced.

[0147] This can improve durability by reducing the possibility of deformation or breakage of the measuring pins and extend the lifespan of the pin block unit.

[0148] That is, the spacing structure of the lower inclined body (550) of the present invention can play an important role in enhancing the performance and reliability of the pin block unit by providing various advantages such as maintaining stable contact with the camera module, ease of insertion and separation, and improved durability of the measuring pins.

[0150] Next, the assembly process of the pin block unit according to the present invention is described.

At this time, the upper horizontal body (520), which is bent at the top of the vertical body (510), is fitted into and fixed in the second fixing groove (212). Here, the inclined body (530), which slopes upward from the end of the upper horizontal body (520), elastically contacts the other upper corner of the upper elastic body (300). Then, the end of the bent section (531), which is bent downward from the end of the inclined body (530), is in contact with the upper part of the upper elastic body (300) or is spaced upward at a certain height.

[0166] And the lower inclined body (550) formed at the bottom of the vertical body (510) is spaced apart from the inclined surface (S) formed on the right side of the second pin block body (220).

[0170] Accordingly, as shown in FIG. 10, the measuring pins (500) are installed symmetrically on both sides of the pin block body (200).

[0171] Each end of the bent portion (531) of the measuring pins (500) can be in contact with the upper surface of the upper elastic body (300). At the same time, each inclined body (530) of the measuring pins (500) is elastically supported on both upper corners of the upper elastic body (300).

[0172] Of course, guide grooves (not shown) capable of guiding the flow of the ends of the bent ends (531) may also be formed at the upper two corners of the upper elastic body (300).

[0173] Accordingly, the bent portion between the inclined body (530) and the bent end (531) of each of the measuring pins (500) can form a structure that can be elastically connected to the connection terminal of the PCB (10) along the upward direction.

[0174] The impact generated when the bent portion between the inclined body (530) and the bent end (531) of each of the measuring pins (500) is elastically connected to the connection terminal of the PCB (10) can be absorbed by the upper elastic body (300) in a state where the bent ends (531) are in contact with the upper surface of the upper elastic body (300). At the same time, because the inclined bodies (530) are elastically in contact with the upper two corners of the upper elastic body (300), deformation of the bent shape between the bent ends (531) and the inclined bodies (530) can be prevented.

[0175] In addition, since the end of the lower horizontal body (540) of each of the measuring pins (500) is in a state of elastic contact with the lower elastic body (400), the impact generated when they come into contact with the terminals (21) of the connector (20) can also be easily absorbed by the elasticity of the lower elastic body (400).

[0176] Here, a groove (not shown) is further formed at the bottom of the lower elastic body (400) so that the upper end portion of the lower horizontal body (540) of the measuring pins (500) can be inserted, thereby allowing for more stable shock absorption and prevention of posture distortion.

[0177] In addition, the effect predicted by the configuration in the present invention, in which the end of the bending section (531), which is bent downwardly at the end of the inclined body (530), contacts the upper part of the upper elastic body (300) or is spaced upward at a certain height, is as follows.

[0178] It can achieve a stable connection with the PCB connection terminals and shock absorption.

[0179] By positioning the end of the bending section (531) in contact with or close to the upper part of the upper elastic body (300), the connection stability between the connection terminal of the PCB and the measurement pin can be increased.

[0180] In the event of an external shock or vibration, the upper elastic body (300) acts as a buffer to prevent the connection between the measurement pin and the PCB connection terminal from being severed or damaged.

[0181] In particular, when the bending end (531) comes into direct contact with the upper elastic body (300), the pressure applied to the measuring pin can be effectively dispersed, thereby further improving connection stability.

[0182] It is possible to ensure the flexibility of the measurement pins and prevent PCB damage.

[0183] When the bending section (531) is spaced a certain height away from the upper elastic body (300), it provides some flexibility to the measuring pin. This allows the measuring pin to bend or move to some extent when there is a slight error in the position of the connection terminal on the PCB or when external pressure is applied, thereby preventing damage to the PCB. In addition, the possibility of deformation or breakage of the measuring pin itself can be reduced.

[0184] In addition, ease of assembly and maintenance of the pin block unit can be achieved.

[0185] A structure in which the end of the bending section (531) contacts or is separated from the upper elastic body (300) can simplify the assembly and disassembly process of the measuring pin. During the process of inserting and fixing the measuring pin into the pin block body, there is no need to accurately align the position of the bending section (531) or go through a complex assembly procedure. This can increase the production efficiency of the pin block unit and facilitate maintenance.

[0186] That is, the end position of the bending section (531) can play an important role in improving the performance and reliability of the pin block unit in various aspects, such as stable connection with the PCB connection terminal, shock absorption, securing flexibility of the measuring pin, prevention of PCB damage, and ease of assembly and maintenance.

[0187] In addition, although not shown in the drawing, if the upper corners on both sides of the upper elastic body are formed into curved surfaces to contact the inclined bodies of the measuring pins, the following effect may be achieved.

[0188] It is possible to increase the contact area with the measuring pin and improve stability.

[0189] The curved shape increases the contact area between the inclined body of the measuring pin and the surface compared to a flat surface. This allows the measuring pin to be supported more stably by the upper elastic body, thereby increasing resistance to external shocks or vibrations. In particular, it can improve connection stability by preventing slippage or misalignment that may occur when the measuring pin is inserted or moved.

[0190] It is possible to achieve stress distribution and improved durability for the measuring pin.

[0191] The curved shape has the effect of distributing the pressure applied to the measuring pin over a wider area. This prevents stress from concentrating in specific areas, thereby reducing the possibility of deformation or breakage of the measuring pin. As a result, it can improve the durability of the measuring pin and extend the lifespan of the pin block unit.

[0192] It is possible to ensure the movement flexibility of the measuring pin.

[0193] The curved shape allows the measuring pin to move relatively freely while in contact with the upper elastic body. This enables the measuring pin to flexibly respond to positional errors in the PCB connection terminals or changes in external pressure, thereby preventing PCB damage or breakage of the measuring pin. In particular, it ensures that the measuring pin moves smoothly when inserting and removing the camera module.

[0194] The curved shape facilitates the insertion and securing process of the measuring pin. When inserting the measuring pin into the pin block body, the curve acts as a guide to accurately position the pin. Additionally, when removing the measuring pin, the curved shape smoothly guides the pin, allowing for removal without damage.

[0195] According to the above configuration and operation, the present invention fixes a plurality of wire pins to both sides of a core block, enables the upper and lower ends of the wire pins to move elastically independently, and separates a portion of the wire pins from both sides of the core block so that the shock generated when the upper and lower ends of the wire pins come into contact with a PCB and a connector module is dispersed, thereby enabling stable electrical characteristic testing and improving the accuracy of the test.

[0196] Although the present invention has been described above with reference to the illustrated drawings, the present invention is not limited by the embodiments and drawings disclosed in this specification, and it is obvious that various modifications can be made by a person skilled in the art within the scope of the technical concept of the present invention. Furthermore, even if the effects of the configuration of the present invention were not explicitly described while explaining the embodiments of the present invention above, it is natural to acknowledge that the effects predictable by said configuration should also be recognized.
