Description

Technical Field

[0002] As a modern and highly innovative interface technology, the application of TYPE-C connector in the field of electronic equipment has become increasingly widespread. Its unique setting and diverse functional characteristics make it stand out among many interface technologies and become the mainstream choice of electronic equipment interface. At present, in the production and assembly process of TYPE-C connector, direct welding is a common method. For example, the Chinese utility model patent disclosure specification CN220382360U discloses a Type-C connector that is resistant to bending and large shear force. However, this direct welding method still has some problems in practical applications. First, the direct welding method requires the terminal to be inserted into the hole of the PCB circuit pad, which will undoubtedly take up a large space. In some occasions with limited space, this method may be stretched and increase the difficulty of planning the PCB circuit pad. In addition, since the terminals need to be inserted into the circuit board one by one, the assembly process may become relatively time-consuming, which not only affects the production efficiency, but also increases the processing difficulty of the SMT process. In view of the above problems, how to reduce the planning difficulty of the PCB circuit pad and reduce the processing difficulty of the SMT process is still an important issue that technicians in this field need to pay attention to.

[0007] Furthermore, the utility model provides a TYPE-C connector, wherein a hook plate is sandwiched between the upper mounting seat and the lower mounting seat, the front half of the hook plate is sandwiched between the upper mounting seat and the lower mounting seat, and two hook bodies extending backwards are symmetrically provided on the left and right sides of the rear half of the hook plate, and hooks are provided on the opposite side ends of the two hook bodies.

[0008] Furthermore, the utility model provides a TYPE-C connector, wherein a hook plate is sandwiched between the upper mounting seat and the lower mounting seat, the middle part of the hook plate is sandwiched between the upper mounting seat and the lower mounting seat, two hook bodies extending backwards are symmetrically provided on the left and right sides of the rear half of the hook plate, and hooks are provided on the opposite side ends of the two hook bodies, and two positioning protrusions extending forwards are symmetrically provided on the left and right sides of the front half of the hook plate, and the positioning protrusions pass through the shell.

[0009] Furthermore, the utility model provides a TYPE-C connector, which also includes a fixing sleeve, which is fixed to the front half of the shell, and L-shaped connecting ear plates are symmetrically provided on the left and right sides of the fixing sleeve, and the front end surface of the connecting ear plate is flush with the front end surface of the flat welding part.

[0010] Furthermore, the utility model provides a TYPE-C connector, wherein an upper positioning protrusion extending upward is provided in the middle of the upper surface of the upper half mounting seat, and the upper half mounting seat is connected to an upper protective cover covering the head of the upper conductive terminal through the upper positioning protrusion, and the upper protective cover is fixed to the upper side of the rear half of the shell by a snap connection.

Sufficient spacing can ensure that the flat welding part can absorb enough solder on the PCB circuit pad and effectively avoid the problem of short circuit between the flat welding parts. In addition, the flat welding parts can be evenly distributed in a vertical plane, which can reduce the occupied space, make the circuit board more compact, and effectively reduce the difficulty of the SMT (surface mounting technology) process.

At the same time, since the welding quality has been significantly improved, the accuracy and stability of the circuit connection have also been greatly improved. In addition, the utility model also helps to reduce the difficulty of PCB circuit pad planning. In the traditional pad setting, the pad planning is often very difficult due to the small spacing between the soldering parts or the unreasonable layout. However, after adopting this flat soldering part setting, the pad planning becomes simpler and more flexible, which is conducive to improving production efficiency and reducing production costs.

[0020] A TYPE-C connector of the present invention is explained and illustrated in detail below in conjunction with the drawings in the specification.

[0021] First embodiment

[0022] like Figure 1-3As shown, the utility model discloses a TYPE-C connector, which includes a cylindrical shell 1. The cross-sectional shape of the shell 1 is in the shape of a runway, which can effectively resist external impact and extrusion, and ensure the stability and durability of the connector. A split upper half mounting seat 2 and a lower half mounting seat 3 are fixed in the front half of the shell 1. An upper conductive terminal 4 is provided in the upper half mounting seat 2, and a lower conductive terminal 5 is provided in the lower half mounting seat 3. The upper conductive terminal 4 and the lower conductive terminal 5 are made of high-quality materials and have good conductivity and corrosion resistance. The heads of the upper conductive terminal 4 and the lower conductive terminal 5 extend backward and are respectively distributed on the upper and lower sides of the rear half of the shell 1. This layout enables the connector to maintain a good contact effect when inserted and unplugged, ensuring the stability of signal transmission. It is worth mentioning that after the tails of the upper conductive terminal 4 and the lower conductive terminal 5 extend out of the housing 1, they are bent vertically upward or downward to form a flat welding portion 6 (that is, the parts of the tails of the upper conductive terminal 4 and the lower conductive terminal 5 extending out of the housing 1 have two bending methods, one is to bend vertically downward, and the other is to bend vertically upward. In actual application, they can be bent according to the actual planning of the PCB circuit board, and the bent parts form flat welding portions 6). These flat welding portions 6 form two rows, upper and lower, and each row has two adjacent flat welding portions 6 spaced apart. Such a setting ensures that the front end surfaces of each flat welding portion 6 are flush with each other, and that there is a sufficient spacing between each adjacent flat welding portion 6. Such a spacing setting can effectively avoid the problem of short circuit between the flat welding portions 6, while ensuring that the solder can evenly cover the welding portion, thereby improving the welding quality. In addition, the layout of the flat soldering portion 6 has many advantages: the flat soldering portion 6 can be evenly distributed in a vertical plane, thereby reducing the occupied space and making the circuit board more compact, which helps to reduce the difficulty of the SMT (surface mount technology) process and improve production efficiency; since the flat soldering portion 6 is reasonably laid out, positioning and mounting during the SMT process become easier, which not only improves production efficiency but also reduces production costs; in addition, this setting also helps to reduce the difficulty of PCB circuit pad planning. In traditional pad settings, due to the small spacing between the soldering portions or unreasonable layout, pad planning often brings great difficulties. After adopting this flat soldering portion 6 setting, pad planning becomes simpler and more flexible, which is conducive to improving production efficiency and reducing production costs; since the welding quality has been significantly improved, the accuracy and stability of the circuit connection have also been greatly improved, thereby improving the performance and reliability of the entire electronic equipment.

[0023] Based on the above embodiment, as an optimization scheme, the flat welding portion 6 located in the upper row is staggered with the adjacent flat welding portion 6 located in the lower row. This staggered distribution method can effectively avoid the problem of short circuit between the flat welding portions 6 between the upper row and the lower row. In practical applications, short circuits are often caused by the close distance between the welding portions or improper layout, and the staggered distribution can solve this problem to a certain extent. By staggering the flat welding portions 6 between the upper row and the lower row, it can be ensured that there is a sufficient spacing between them, thereby avoiding the risk of short circuit caused by contact between the welding portions. In addition to the staggered distribution, the lower half of the flat welding portion 6 that is bent vertically upward is embedded in the front end face of the upper half mounting seat 2, and the upper half of the flat welding portion 6 that is bent vertically downward is embedded in the front end face of the lower half mounting seat 3. This setting can not only fix the root of the flat welding portion 6, but also ensure that the front end face of the flat welding portion 6 is completely exposed as a welding surface. Specifically, this embedded setting can make the flat welding part 6 more stably fixed on the mounting base, reducing the risk of the welding part loosening or falling off due to vibration or external force. At the same time, by completely exposing the welding surface, it can ensure that the contact area between the welding surface and the PCB circuit pad is maximized during the welding process, thereby improving the welding quality and stability. In addition, this connection structure can also ensure the connection stability of the flat welding part 6 without affecting the welding of the flat welding part 6 and the PCB circuit pad. In practical applications, it is necessary to ensure that the connection between the welding part and the pad is both stable and reliable to ensure the normal operation of the entire circuit, and this embedded setting method can just meet this demand. It can not only fix the welding part, but also ensure that the welding surface is completely exposed, thereby achieving a balance between connection stability and welding reliability.

[0024] Based on the above embodiment, as an optimization scheme, a hook plate 7 is sandwiched between the upper half mounting seat 2 and the lower half mounting seat 3, and the front half of the hook plate 7 is hidden between the upper half mounting seat 2 and the lower half mounting seat 3, forming a stable support structure. Two hook bodies 71 extending backward are symmetrically arranged on the left and right sides of the rear half of the hook plate 7, and a hook 72 is arranged at the end of the opposite side of each hook body 71. The hook 72 is used to combine with the notch on the side of the socket (the socket of the female seat), thereby ensuring that the connector can be firmly fixed on the socket and is not easy to loosen, which not only improves the stability of the connection, but also greatly enhances the safety of use. It is worth mentioning that the hook body 71 is not a simple rigid structure, but has a certain elastic force. When it is slightly vibrated or moved, the hook body 71 can automatically adjust its position to maintain a stable connection state, thereby avoiding loosening or falling off of the connection caused by vibration or movement. This setting not only ensures the stability of the connection, but also improves the convenience of use. In addition, the setting of the hook 72 also fully considers practicality and durability, and is preferably made of wear-resistant and corrosion-resistant materials to ensure the long service life of the connector. At the same time, the hook body 71 has a certain elastic force, which not only ensures the firmness of the connection, but also avoids damage caused by excessive force. More importantly, the setting of the hook 72 allows multiple connection and disassembly operations, so that users can replace or adjust the connector at any time as needed without worrying about interface damage or affecting service life. This flexibility and convenience greatly improves the practicality of the connector.

[0025] Based on the above embodiment, as an optimization scheme, a fixing sleeve 11 is further included. The fixing sleeve 11 is sleeved and fixed on the front half of the housing 1. L-shaped connecting ear plates 111 are symmetrically provided on the left and right sides of the fixing sleeve 11. The fixing sleeve 11 is used to fix the housing 1 on the PCB circuit board, which greatly simplifies the installation steps and improves the work efficiency. The fixing sleeve 11 can be firmly fixed on the PCB circuit board through the tight fit between the connecting ear plate 111 and the PCB circuit board, so that the housing 1 can be firmly fixed on the PCB circuit board, and it is not easy to loosen or shift. The front end surface of the connecting ear plate 111 is flush with the front end surface of the flat welding part 6. Therefore, when performing the welding operation, the connecting ear plate 111 will not suspend the flat welding part 6, thereby avoiding interference and inconvenience during the welding process. In actual operation, the existence of the connecting ear plate 111 does not cause any hindrance to the welding operation, but can provide better support and stability, making the welding process smoother and more efficient.

[0026] Based on the above embodiment, as an optimization scheme, an upper positioning protrusion 21 extending upward is provided in the middle of the upper surface of the upper half mounting seat 2. The upper positioning protrusion 21 not only plays a positioning role, but also serves as a connecting component, and is connected to the upper protective cover 8 covering the head of the upper conductive terminal 4. The upper protective cover 8 is firmly fixed to the inner upper side of the rear half of the shell 1 by a snap connection, which effectively enhances the overall structural stability of the connector. An upper snap 81 is provided on the upper surface of the front half of the upper protective cover 8, and the upper snap 81 matches the upper card groove 12 provided on the upper wall of the front half of the shell 1, making the installation of the upper protective cover 8 more convenient and stable. In addition, an upper receiving groove 22 is also provided on the lower surface of the upper protective cover 8, and the head of the upper conductive terminal 4 is cleverly placed therein, thereby achieving effective protection of the conductive terminal. Three upper connecting snaps 23 are provided inside the upper protective cover 8, and the ends of the upper connecting snaps 23 adopt a U-shaped structure. This arrangement not only enhances the strength of the snaps, but also makes the snaps more firm and reliable when fixed. The main function of the upper connection buckle 23 is to limit and fix, so as to prevent the connector from being loosened due to a slight external force when in use. Only when the external force exceeds the limit value can the connector be pulled out, thereby ensuring the safety of the connector. Corresponding to the upper half mounting seat 2 is the lower half mounting seat 3. The middle part of the lower surface of the lower half mounting seat 3 is provided with a lower positioning protrusion extending downward, and the lower positioning protrusion plays the same role as the upper positioning protrusion 21 of the upper half mounting seat 2. The lower half mounting seat 3 is connected to the lower protective cover 9 covering the head of the lower conductive terminal 5 through the lower positioning protrusion. The lower protective cover 9 is also fixed to the lower side of the rear half of the shell 1 by a buckle connection, ensuring the stability and reliability of the lower half. The lower surface of the front half of the lower protective cover 9 is provided with a lower buckle 91, which matches the lower card slot 13 provided on the lower peripheral wall of the front half of the shell 1, so that the installation of the lower protective cover 9 is also simple and firm. The upper surface of the lower protective cover 9 is provided with a lower receiving groove 92, in which the head of the lower conductive terminal 5 is placed, thereby achieving effective protection for the lower conductive terminal 5. Similar to the upper protective cover 8, three lower connecting buckles 93 are also provided inside the lower protective cover 9. The end of the lower connecting buckle 93 adopts an inverted U-shaped structure. This arrangement not only ensures the strength of the buckle, but also makes the buckle more stable when fixed. The lower connecting buckle 93 also plays a role of limiting and fixing, ensuring the stability and safety of the connector when in use. Through the arrangement of the upper protective cover 8 and the lower protective cover 9, not only can the head of the conductive terminal be effectively shielded, but also the contact reliability of the connector can be improved. At the same time, the arrangement of the upper connecting buckle 23 and the lower connecting buckle 93 makes it difficult for the connector to loosen when subjected to external force, thereby ensuring the stable transmission of the connector.In addition, by providing the upper connecting buckle 23 and the lower connecting buckle 93, the connector has an excellent tactile function. When inserting, due to the existence of the upper connecting buckle 23 and the lower connecting buckle 93, an obvious sense of paragraph will be generated, which helps the user to confirm that the wire has been correctly inserted and inserted into place during blind operation. This setting not only improves the user experience, but also enhances the safety and reliability of the equipment.

[0027] Second embodiment

[0028] like Figure 4 Combined with Figure 5 As shown, the difference from the first embodiment is that: a hook plate 7 is sandwiched between the upper half mounting seat 2 and the lower half mounting seat 3, and the middle part of the hook plate 7 is hidden between the upper half mounting seat 2 and the lower half mounting seat 3, forming a stable support structure. Two hook bodies 71 extending backward are symmetrically arranged on the left and right sides of the rear half of the hook plate 7, and a hook 72 is arranged at the end of the opposite side of each hook body 71. The hook 72 is used to combine with the notch on the side of the socket (the socket of the female seat), thereby ensuring that the connector can be firmly fixed on the socket and is not easy to loosen, which not only improves the stability of the connection, but also greatly enhances the safety of use. Two unique positioning protrusions 73 are symmetrically arranged on the left and right sides of the front half of the hook plate 7, and the two positioning protrusions 73 pass through the housing 1. Through the two positioning protrusions 73, the connector can be accurately and accurately positioned with the PCB circuit board, laying a solid foundation for subsequent connection and welding work. The shape and size of the positioning protrusion 73 ensure that it can match the corresponding interface on the PCB circuit board. When the connector contacts the PCB, the positioning protrusion 73 will first contact its interface to achieve preliminary fixation and positioning. This pre-positioning method not only makes the connection more stable, but also greatly simplifies the subsequent welding steps. With the presence of the positioning protrusion 73, the alignment between the connector and the PCB is more accurate, thereby reducing the error and rework rate during the welding process. This not only improves production efficiency, but also reduces production costs, bringing tangible economic benefits to the enterprise.

[0029] It should be noted that a general TYPE-C connector (male socket) has two symmetrical rows of terminals, the upper row of terminals includes 12 terminals A1-A12, and the lower row of terminals includes 12 terminals B1-B12. The terminals A1-A12 are GND, SSTXp1, SSTXn1, VBUS, CC1, Dp1, Dn1, SBU1, VBUS, SSRXn2, SSRXp2 and GND, respectively, and the terminals B1-B12 are GND, SSRXp1, SSRXn1, VBUS, SBU2, Dn2, Dp2, CC2, VBUS, SSTXn2, SSTXp2 and GND, respectively. In the first embodiment and the second embodiment, the number of the upper conductive terminals 4 and the lower conductive terminals 5 can be set according to actual needs. The attached figure shows a schematic diagram of the structure of the 9-terminal layout, which includes terminals B11, A7, A5, A3, A1 and terminals B10, A9, A6, A2. Of course, it is understandable that it can be set to other numbers while meeting the setting function, such as setting it to 5 terminals (that is, only including some core pins, such as the positive and negative poles of power supply and the positive and negative poles of data, to achieve basic power supply and data transmission functions) etc.
