Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a high-speed connector with a hot air convection structure. Background Technology

[0002] The heat flow path refers to the trajectory of heat transfer from the heat source to the heat dissipation area in an electronic component. In the SMT (Surface Mount Technology) process, heat flow path management during the reflow soldering stage is particularly critical, directly determining the consistency of solder joint formation and the long-term reliability of the component. The heat flow path refers to the specific process by which hot air is transferred to the PCB surface and solder paste in the reflow oven. The uniformity and stability of the heat flow path are crucial for soldering quality. In practice, ensuring that temperature and airflow are evenly distributed to each solder joint is key to achieving high-quality soldering.

[0003] During the connector-PCB connection process, the connector's large plastic shell covers the PCB, and the bottom of the shell is closed, hindering the even heating of all connector pins and solder pads by hot air. This causes temperature differences between solder joints, resulting in incomplete melting of the solder paste, incomplete soldering, cold soldering, and affecting the consistency of the soldering. Therefore, it is urgent to optimize the hot air path to effectively reduce the problem of uneven heating in the heat flow path and avoid excessively high or low local temperatures of components, which can lead to soldering defects.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please refer to the attached document. Figures 1-9 This utility model proposes a high-speed connector with a hot air convection structure, including a plastic shell 100, a slot 200, and several sets of terminal assemblies 300. The plastic shell 100 includes a front end and a rear end, and a convection structure 110 is provided on the plastic shell 100, connecting the front end and the rear end of the plastic shell 100. The convection structure 110 includes a convection cavity 111 and several convection holes 112. The convection cavity 111 penetrates the plastic shell 100. The convection holes 112 are symmetrically arranged on both sides of the plastic shell 100, and a portion of the convection holes 112 are connected to the convection cavity 111. One part of the convection cavity 111 is connected to the other part of the convection hole 112, which is located at one end of the convection cavity 111. The top of the convection cavity 111 and the plastic shell 100 form a first slot 210. The bottom of the convection cavity 111 and the plastic shell 100 form a second slot 220. The plastic shell 100 is also provided with a limiting block 400 for fixing the terminal assembly 300 and providing support. The limiting block 400 is also provided with a limiting block 400 for hot air circulation. The convection cavity 111 and the convection hole 112 are respectively connected to the limiting block 400. The bottom of the plastic shell 100 is provided with a groove 120, which is connected to the limiting block 400.

[0018] Specifically, the large plastic shell 100 of the connector covers the PCB, and the bottom of the shell 100 is closed, forming a localized "thermal barrier" that hinders hot air from evenly heating all the connector pins and solder pads. This can lead to temperature differences at various solder joints, affecting soldering consistency. Optimizing the hot air path effectively reduces thermal stress and prevents component warping or cold solder joints.

[0019] In this embodiment, the plastic shell 100 is provided with a hot air convection structure 110, wherein the convection structure 110 includes a convection cavity 111 and a plurality of convection holes 112. The convection cavity 111 extends from the front end of the plastic shell 100 to the rear end of the plastic shell 100; the convection holes 112 are symmetrically arranged on both sides of the plastic shell 100, specifically located at the rear end of the plastic shell 100, and some of the convection holes 112 communicate with the convection cavity 111. The convection cavity 111 and the convection holes 112 allow hot air from the front end and sides of the plastic shell 100 to circulate. When heated by hot air convection from both the front and sides, the heat flux received by the soldering area of ​​the solder plate and the connector is more uniform, reducing local temperature differences (such as thermal gradients). The uniform temperature field allows the solder paste to reach the active temperature zone simultaneously and melt uniformly, thereby improving the solder joint quality.

[0020] A convection cavity 111 is located in the middle of the plastic shell 100. The top of the convection cavity 111 and the plastic shell 100 form a first slot 210, and the bottom of the convection cavity 111 and the plastic shell 100 form a second slot 220. The first slot 210 and the second slot 220 are respectively used to place terminal assemblies 300. The terminal group 310 includes a first terminal group 311, a second terminal group 312, a third terminal group 313, and a fourth terminal group 314. Each terminal assembly 300 also includes a terminal and a fixing base 320. The terminal includes a signal terminal and a ground terminal, and several ground terminals are respectively provided with grounding plates 500. A limiting block 400 or a limiting boss is provided between the two terminal groups 310, mainly used to fix the terminal group 310 and provide support for the terminal group 310. The limiting block 400 is further provided with a limiting block 400 for hot air circulation. One side of the limiting block 400 is connected to the convection cavity 111 and the convection hole 112 respectively, and the other side is connected to the groove 120 provided at the bottom of the plastic shell 100. The groove 120 is recessed from the bottom of the plastic shell 100 toward the top of the plastic shell 100. The fixing seat 320 of the terminal assembly 300 and the end of the limiting block 400 near the bottom of the plastic shell 100 are flush with the bottom of the groove 120 at the bottom of the plastic shell 100. The end of the terminal connected to the solder plate is convex relative to the plane of the opening of the groove 120 of the plastic shell 100, so that the hot air can be blown more directly to the solder plate and the pin area of ​​the connector, which helps to make the heating of each solder point more uniform, thereby forming solder points with more consistent quality.

[0021] Please refer to Figure 5 The plastic housing 100 has track grooves 130 on both sides, the first slot 210 and the second slot 220 respectively, which provide guidance for the terminal assembly 300.

[0022] In specific implementation: Track grooves 130 are respectively provided on the left and right sides of the plastic shell 100 and inside the first slot 210 and the second slot 220. The fixing seat 320 on the terminal assembly 300 is respectively provided with sliders 321 corresponding to the track grooves 130. During assembly, the track grooves 130 serve as the assembly guide direction for the terminal assembly 300. The sliders 321 of the fixing seat 320 of the terminal assembly 300 cooperate with the track grooves 130 and move along the designated track grooves 130 to complete the assembly.

[0023] Please refer to Figure 1 , Figure 6 and Figure 8 The terminal assembly 300 includes a terminal group 310 and a fixing seat 320. The fixing seat 320 is arranged in a U-shape. The fixing seat 320 is provided with sliders 321 corresponding to the track groove 130, and is located at both ends and the middle of the fixing seat 320 respectively. The fixing seat 320 is also provided with a connecting block 322, which is located at one end of the fixing seat 320 near the bottom of the plastic shell 100. The limiting block 400 is provided with a connecting hole 420 corresponding to the connecting block 322, and the connecting block 322 cooperates with the connecting hole 420. The fixing seat 320 is also provided with a buckle 323 and several bosses 324. The buckle 323 is located at both ends of the fixing seat 320, and the bosses 324 protrude from the main body surface of the fixing seat 320, and the protrusion height is consistent.

[0024] In practical implementation: The terminal assembly 300 includes a terminal group 310 and a mounting base 320. The mounting base 320 is arranged in a U-shape, providing more contact points between the terminals and the mounting base 320, which helps ensure that the connector terminals are not easily detached when subjected to mechanical forces or temperature changes. The U-shaped structure can effectively reduce the transmission of vibration or impact forces to the terminals, helping to reduce poor contact caused by vibration. At the same time, the U-shaped structure can also increase the electromagnetic shielding effect between the connector terminals and the ground or other components, reducing the propagation of electromagnetic interference (EMI), which is particularly important for applications with high requirements for high-speed signal transmission or electromagnetic interference resistance.

[0025] Specifically, the sliders 321 on the fixing base 320 correspond to the track grooves 130 on both sides of the plastic shell 100 and in the first slot 210 and the second slot 220, respectively. During assembly, the track grooves 130 guide the fixing base 320, allowing it to mate with the plastic shell 100 along the preset track. Several connecting blocks 322 are also provided on opposite sides of the middle portion of the fixing base 320, specifically on opposite sides of the end of the fixing base 320 near the bottom of the plastic shell 100. The connecting blocks 322 protrude from the main surface of the fixing base 320 and are arranged opposite each other, i.e., one in front of the other. The limiting block 400 has connecting holes 420 corresponding to the connecting blocks 322. During assembly, the connecting blocks 322 of the fixing base 320 are all on the same straight line. The connecting blocks 322 of the fixing base 320 mate with the connecting blocks 322 of the limiting block 400, ensuring that the force path is designed on the same straight line. This straight force makes the connection between adjacent terminal assemblies 300 more stable.

[0026] In one embodiment, the I-shaped design simplifies the terminal manufacturing process, avoiding complex support structures or designs requiring multiple processing steps. Such designs are generally easier to mass-produce while reducing production costs.

[0027] The mounting base 320 is also provided with several bosses 324. These bosses 324 protrude at the same height relative to the main surface of the mounting base 320 and are linearly arranged. The bosses 324 directly contact the plastic shell 100 or the clamp to form a controlled height reference surface, ensuring that the terminals are located in the same plane. The presence of the bosses 324 enhances the overall mechanical strength, compressive strength, and long-term stability of the connector.

[0028] Please refer to Figure 1 , Figure 6 , Figure 9 and Figure 10 A grounding plate 500 is provided on a plurality of grounding terminals of terminal group 310; a plurality of grounding terminals located in the first slot 210 and the second slot 220 are also provided with grounding plates 500; an extension 600 is provided on the grounding plate 500, and a placement slot 325 for placing the extension 600 is provided on the fixing base 320.

[0029] In specific implementation: the terminal assembly 300 includes a first terminal group 311, a second terminal group 312, a third terminal group 313, and a fourth terminal group 314; each terminal group 310 has a corresponding grounding piece 500 on its grounding terminal, part of which is located on the terminal mounting base 320, and the other part is fixed to the head of the terminal (i.e., on several grounding terminals located in the first slot 210 and the second slot 220) by spot welding. The distribution of the grounding pieces 500 can effectively control electromagnetic resonance and ensure signal integrity. The grounding piece 500 located at the head of the terminal inserts a low-impedance grounding reference point between the signal terminals, providing a preferred path for the return current of the high-speed signal, greatly reducing the loop area formed by the signal and the return path. The reduction in loop area directly reduces the magnetic field strength generated by the signal, thereby significantly reducing inductive crosstalk. At the same time, the grounding piece 500 located at the head of the terminal can provide a low-impedance path to guide and dissipate the oscillation energy, fundamentally suppressing the maintenance of resonance. A portion of the grounding piece 500 mounted on the mounting base 320 has several through holes corresponding to the bosses 324 of the mounting base 320. When the grounding piece 500 is placed on the mounting base 320 of the terminal, the bosses 324 on the mounting base 320 penetrate the grounding piece 500. Simultaneously, the extension 600 on the grounding piece 500 is located within the placement groove 325 of the mounting base 320, thereby ensuring that the relative position of the grounding piece 500 and the terminal remains stable, preventing displacement of their relative positions due to manufacturing errors or mechanical impacts. It also prevents impedance instability caused by changes in the distance between the signal terminal and the grounding piece 500.

[0030] Please refer to Figure 1 and Figure 7 The mounting base 320 has an air groove 326 at one end near the slot. The air groove 326 extends into the interior of the mounting base 320 until it abuts against the terminal group 310.

[0031] In a specific implementation: the terminal assembly 300 includes a first terminal group 311, a second terminal group 312, a third terminal group 313, and a fourth terminal group 314; the first terminal group 311 cooperates with the second terminal group 312 and is inserted into the second slot 220, and the third terminal group 313 and the fourth terminal group 314 cooperate and are inserted into the first slot 210. Air grooves 326 are respectively provided on the two sides of the fixing base 320 that cooperate with the first terminal group 311 and the second terminal group 312, and air grooves 326 are also respectively provided on the two sides of the fixing base 320 that cooperate with the third terminal group 313 and the fourth terminal group 314. The air grooves 326 extend inwards towards the fixing base 320 and abut against terminals that are injection-molded into the fixing base 320 via inserts. An air groove 326 is provided on the terminal holder 320, which is equivalent to introducing a low dielectric constant air region into the plastic dielectric. Since the capacitance is proportional to the dielectric constant, introducing air next to the terminal reduces the effective dielectric constant of this region, thereby increasing the characteristic impedance of this region and making the impedance curve inside the connector flatter and closer to the target impedance value. The air groove 326 can also serve as dielectric isolation, increasing the effective dielectric distance between adjacent terminals or forming a physical barrier, reducing electric field coupling between them, and suppressing high-frequency resonance.

[0032] Please refer to Figures 5-7 The plastic shell 100 is provided with a locking hole 140, and the fixing base 320 is provided with a buckle 323 corresponding to the locking hole 140.

[0033] In practical implementation: the rear end of the plastic shell 100 is provided with several locking holes 140, specifically located in the track grooves 130 on both sides of the plastic shell 100. The locking holes 140 are mainly located at the top and bottom of the plastic shell 100. The fixing seat 320 of the fourth terminal group 314 is provided with a buckle 323 corresponding to the locking holes 140. The buckle 323 protrudes from the side of the fixing seat 320 near the plastic shell 100, and the buckle 323 has a slope facing the front end of the plastic shell 100. During assembly, the fixing seat 320 moves along the track groove 130 into the plastic shell 100 until the buckle 323 on the fixing seat 320 of the fourth terminal group 314 engages with the locking holes 140 at the rear end of the plastic shell 100. The buckle 323 makes the connection between the terminal assembly 300 and the plastic shell 100 more secure.

[0034] Please refer to Figure 1 and Figure 5 The convection cavity 111 is provided with a support structure 1111, which is arranged in a cross shape and divides the convection cavity 111 into a grid shape.

[0035] In practical implementation: a cross-shaped support structure 1111 is provided inside the convection cavity 111 to distribute the force and reduce the risk of deformation of the convection cavity 111. At the same time, it also increases the strength and reliability of the connector slot 200, preventing permanent deformation of the connector slot 200 during disassembly or under stress.

[0036] Please refer to Figures 5-6 The convection structure 110 is integrally formed with the plastic shell 100, and the slider 321, the boss 324 and the buckle 323 are integrally formed with the fixed base 320 respectively.

[0037] In practical implementation: The convection structure 110, integrally molded on the plastic shell 100, forms a complete continuum, providing not only high structural strength but also better resistance to external impacts and vibrations. In high-vibration application environments, the seamless, integrally molded convection structure 110 will not loosen, thus protecting the terminal assembly 300 inside the plastic shell 100 and ensuring the stability of the connector. Compared to traditional multi-part assembly requiring the production of multiple parts, the slider 321, boss 324, and undercut 323 are integrally molded with the fixing base 320, simplifying the assembly process and significantly improving production efficiency. Simultaneously, it reduces assembly labor and lowers overall manufacturing costs.

[0038] The specific process is as follows: The plastic shell 100 is formed with a convection cavity 111, a track groove 130, a locking hole 140, and several convection holes 112. A support structure 1111 is also formed within the convection cavity 111 to enhance the strength and reliability of the connector slot 200. The fixing base 320 is formed with a slider 321, a boss 324, and a buckle 323. The track groove 130 of the plastic shell 100 corresponds to the slider 321 on the fixing base 320. The locking hole 140 formed by the plastic shell 100 corresponds to the buckle 323 formed by the fixing base 320. The boss 324 formed by the fixing base 320 protrudes relative to the body of the fixing base 320, and the protrusion height is consistent. A plurality of terminals and mounting bases 320 are injection molded into a terminal assembly 300, including a first terminal group 311, a second terminal group 312, a third terminal group 313, and a fourth terminal group 314. The first terminal group 311, the second terminal group 312, the third terminal group 313, and the fourth terminal group 314 are bent to obtain an assembly. The assembly includes a first assembly, a second assembly, a third assembly, and a fourth assembly. The first assembly and the second assembly mate with each other. The sliders 321 on the terminal mounting bases 320 of the first assembly and the second assembly follow the track grooves of the plastic housing 100. Assembly is performed at 130, so that the first and second components are respectively inserted into the second slot 220 formed by the plastic shell 100 and the convection cavity 111; the third and fourth components cooperate, and the sliders 321 on the terminal fixing bases 320 of the third and fourth components and the buckles 323 on the fourth component are assembled along the track groove 130 of the plastic shell 100, so that the third and fourth components are inserted into the first slot 210 formed by the plastic shell 100 and the convection cavity 111. At the same time, the buckles 323 on the fourth component engage with the locking holes 140 on the plastic shell 100.

[0039] Please refer to Figure 1 and Figure 2 The steps of assembling the fittings with the plastic shell 100 include: installing the first fitting and the second fitting together and inserting them into the second slot 220; installing the third fitting and the fourth fitting together and inserting them into the first slot 210.

[0040] In practical implementation, during the assembly of the fittings and the plastic shell 100, the fittings are equipped with limiting blocks 400. Specifically, the limiting blocks 400 separate the second, third, and fourth fittings, and each limiting block 400 is connected to two adjacent fittings. The limiting blocks 400 are spaced apart in the fittings, and the connecting block 322 of the fixing seat 320 of the fittings and the limiting blocks 400 are all on the same straight line, so that the force path of the fittings and the limiting blocks 400 is designed to be on the same straight line. The straight force makes the connection between the terminal assemblies 300 and the terminal assemblies 300 more stable.
