Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector that is easy to solder. Background Technology

[0002] Connectors are indispensable key components in electronic devices, primarily used to achieve electrical connections between circuits. They play a crucial role in signal transmission and power delivery within electronic systems. Their applications are extremely wide-ranging, from computers and communication equipment to high-end fields such as automotive electronics and aerospace. Almost every scenario involving electronic circuit connections relies on connectors. The core function of a connector is to establish a stable electrical connection path, ensuring the safe and reliable transmission of current or signals. It typically consists of contacts, insulators, a housing, and accessories, all working together to achieve the dual functions of mechanical connection and electrical conduction. In the context of the rapid development of modern electronic devices, connectors, as key components for achieving electrical connections, are widely used in many fields such as computers, communications, and automotive electronics. Their performance and quality directly affect the overall stability and reliability of electronic devices. In the connector manufacturing process, the soldering process is a crucial step in ensuring a stable connection between the connector and the circuit board. The quality of the solder directly affects whether the connector can properly perform its signal and power transmission functions.

[0003] Traditional connectors have a relatively mature technology system in solder design and manufacturing, which can meet the needs of some basic application scenarios. However, as electronic devices develop towards miniaturization, integration, and high performance, the performance requirements for connectors are becoming increasingly stringent, and existing connectors are gradually revealing many shortcomings in solder-related aspects.

[0004] In the testing phase, traditional connectors often use a single pin as an independent input or output point during loop testing. This testing mode requires a large number of input / output ports, which not only increases the complexity and cost of the testing equipment but also easily leads to signal interference, poor contact, and other problems due to the large number of ports, resulting in a high false judgment rate and affecting the accuracy and efficiency of the test results. In terms of inspection, the solder pins of some connectors are densely arranged on the solder plate. After being soldered to the PCB board, the solder joints block each other, making manual visual inspection extremely difficult and making it hard to quickly and accurately detect quality problems such as false soldering and missing soldering. Once there are undetected soldering defects, the products may cause equipment failure after entering the market, resulting in serious economic losses and damage to brand reputation. During the soldering process, due to the lack of precise control over the width of the solder pins and the overall dimensions of the product, solder bridging is prone to occur, causing short circuits between adjacent pins, damaging the electrical performance of the connector, reducing the product's pass rate and reliability, and also increasing the rework costs and time costs in the production process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Traditional connector soldering has the following defects: during testing, the single-pin mode requires a large number of ports, which is costly and prone to interference and misjudgment; during testing, the dense solder joints of the solder feet obscure the view, making it difficult to manually identify cold solder joints and missing solder joints; due to imprecise size control, soldering is prone to short circuits, resulting in low pass rate and high rework costs. This invention provides a connector that is easy to solder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a connector that is easy to solder, comprising a metal pin strip, wherein a two-piece molded body is snapped onto the outer surface of the metal pin strip, a contact pin is fixedly connected to the rear end of the two-piece molded body, a shell is fixedly connected to the outer surface of the two-piece molded body, a finished product is assembled onto the outer surface of the two-piece molded body, a solder pad is fixedly connected to the top of the finished product, and a PCB board is soldered to the bottom of the finished product.

[0007] In a preferred embodiment, the metal PIN strip is attached to the outer surface of the solder pad.

[0008] In a preferred embodiment, the outer shell is fitted onto the outer surface of the die-cast body and the contact PIN pin.

[0009] In one preferred embodiment, the two molded bodies and the contact pins are joined together to form a finished product.

[0010] In a preferred embodiment, the solder pad has several solder feet arranged horizontally, and the several solder pads are arranged in a single row.

[0011] In a preferred embodiment, the bottom of the finished product is soldered to the outer surface of the PCB board via a shell.

[0012] In a preferred embodiment, the metal pin strip is not connected to the PCB board.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the finished product assembly can be tested for continuity by treating the metal pin strip as a single input or output point, thus reducing the number of input or output points and consequently reducing the false positive rate. The solder pads of this product are arranged in rows of single pins, allowing for better visual inspection after the PCB is soldered. When false soldering occurs, it can be effectively corrected manually, thereby reducing the product defect rate and improving production efficiency. To prevent solder bridging between pins during soldering, the total width of the solder pad pins is strictly controlled within a reasonable range, and the total width of the product is also set within an appropriate range.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a connector that is easy to solder, including a metal pin strip 11, a double-molded body 12 is snapped onto the outer surface of the metal pin strip 11, a contact pin 13 is fixedly connected to the rear end of the double-molded body 12, a shell 14 is fixedly connected to the outer surface of the double-molded body 12, a finished product 15 is assembled and connected to the outer surface of the double-molded body 12, a solder pad 16 is fixedly connected to the top of the finished product 15, and a PCB board 17 is soldered to the bottom of the finished product 15. The metal pin strip 11 is attached to the outer surface of the solder pad 16, the shell 14 is sleeved on the outer surfaces of the double-molded body 12 and the contact pin 13, the double-molded body 12 and the contact pin 13 are spliced ​​to form the finished product 15, a plurality of solder pads 16 are arranged horizontally, the plurality of solder pads 16 are arranged in a single row, the bottom of the finished product 15 is soldered to the outer surface of the PCB board 17 through the shell 14, and the metal pin strip 11 is not connected to the PCB board 17.

[0024] In this embodiment, an innovative solution using metal pin strips 11 as the overall input or output point is adopted in the 15-group circuit testing stage of the finished product. This simplifies the traditional testing architecture. Compared with the cumbersome method of requiring multiple ports for independent testing of single pins, the integrated testing significantly reduces the number of input and output points. This design optimization reduces misjudgments caused by poor port contact and signal interference, making the testing process more stable and reliable, and significantly improving testing efficiency and accuracy. The solder pads 16 of the product adopt a single-row single-pin arrangement, which greatly facilitates manual quality inspection. On the soldered PCB board, the solder joints are clear and independent, and quality inspectors can quickly find common defects such as cold solder joints and missing solder joints by visual inspection. Compared with the traditional dense arrangement of solder joints, the single-row single-pin layout significantly improves the efficiency of manual visual inspection and the accuracy of defect identification. Once a false soldering problem is detected, maintenance personnel can quickly locate and repair it, avoiding a complex desoldering process, effectively shortening rework time, and improving production efficiency and yield. To ensure that no solder bridging occurs between the pins during the soldering process, the total width of the solder pins is strictly controlled within a reasonable range, and the total width of the product is also set within an appropriate range. This size design ensures sufficient safety spacing between each pin while also taking into account the miniaturization requirements of the product. Through precise mold design, strict production process control, and welding equipment, solder bridging can be effectively avoided, ensuring the compactness and reliability of the product structure while meeting the electrical performance requirements of the product.

[0025] Working principle:

[0026] like Figures 1-4 As shown, the metal pin strip 11 engages with the secondary molding body 12, and the rear end of the secondary molding body 12 is fixed with the contact pin 13. Simultaneously, the outer shell 14 is fixed to the outer surface of the secondary molding body 12 and assembled with the finished product 15. The finished product 15 has solder pads 16 at its top and a PCB board 17 soldered to its bottom. The outer shell 14 is fitted onto the outer surfaces of the secondary molding body 12 and the contact pin 13. The secondary molding body 12 and the contact pin 13 are joined to form the finished product 15. The metal pin strip 11 adheres to the outer surface of the solder pads 16, and the finished product 15 is soldered to the PCB board 17 via the outer shell 14. During testing... The metal pin strip 11 serves as the overall input / output point, replacing the traditional single-pin multi-port testing, reducing the number of ports, lowering false positives, and improving testing stability and efficiency. The solder pads 16 adopt a single-row, single-pin layout, with clear and independent solder joints, facilitating visual inspection by quality inspectors to detect cold solder joints and missing solder joints. Repair and resoldering can be done quickly, shortening rework time and improving production efficiency and yield. During the soldering process, the width of the solder pad pins and the total width of the product are strictly controlled. With the help of precision molds, production processes, and soldering equipment, the pin spacing is guaranteed to avoid solder bridging, balancing product miniaturization with electrical performance and structural reliability.
