Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of stackable connection type connector module, especially a kind of stackable connection type connector module for connecting multiple connectors by freely stacking multiple modules. BACKGROUND

[0002] The stackable module connector is a connector solution designed for high performance and flexible applications. Its modular structure and high scalability make it particularly suitable for high-precision connection needs of printers, copiers and other automated equipment. Especially in industrial printers, the stackable module connector can achieve efficient connection between multiple nozzle modules, sensors and control modules, meeting the needs of large-format printing, precision label printing and high-demand application scenarios such as printed electronics. It can flexibly integrate various functional modules inside, including nozzle drive modules, environmental sensing modules, data processing modules, power distribution modules and high-speed data interfaces, which not only support stable transmission of data and power, but also ensure efficient system operation. Modular design makes it highly configurable and maintainable, simplifying assembly and replacement processes and reducing operating costs. In addition, its compact structure and excellent anti-interference performance can provide stable and reliable connections in limited space and high-precision demanding environments, making it an indispensable key technology component in modern industrial equipment.

[0003] The structure of the stackable connector module of the prior art usually uses a pair of corresponding male and female connectors for docking and achieves multiple module connector concatenation through board-to-board connection. Specifically, each module needs to weld male and female connectors on the two printed circuit boards on its upper and lower sides, and then concatenate them with board-to-board connectors. However, this design has many challenges and limitations in multi-module connection applications, including complex connector structure, the need for precise manufacturing and assembly, which also leads to increased module thickness and size. Multiple board-to-board concatenations increase the risk of signal attenuation and poor contact, reducing connection reliability. In addition, the installation and maintenance process is complicated, difficult to replace when damaged, and the need for materials and process steps increases, resulting in relatively high costs. In the case of increased module quantity, the circuit design is likely to become too complex, limiting the scalability of the system. Therefore, this technology cannot effectively meet the requirements of high performance and ease of use for multi-module connector structure.

[0004] Therefore, the utility model provides a kind of stackable connection type connector module to solve the problems of complex structure, difficult installation and maintenance and insufficient connection reliability in the prior art. SUMMARY

[0005] The utility model discloses a stackable connector module. The stackable connector module includes a combination of a housing and a connector. The circuit board is connected to the connector and disposed in the housing. The connector includes first and second contact members arranged in an alternating manner and welded on the same side of the circuit board.

The inclined surfaces can reduce the impact when the connector module is connected. The stackable connector module includes a combination of a track groove, a guide block, a recess, and a protrusion. The combination can increase the smoothness of the assembly of the connector module and avoid shaking. In addition, the height of the exposed second contact member, the protrusion, and the guide block can effectively protect the contact members and the connector from damage caused by impact during connection. Therefore, the stackable connector module can be flexibly connected and stacked with other stackable connector modules.

Figure 3 is an exploded schematic view of the stackable connector module 1000 of an embodiment of the present application. The stackable connector module 1000 of the present application is used to connect a circuit board 2000. The stackable connector module 1000 comprises a housing 1 and a connector 2. In detail, the connector 2 is connected to the circuit board 2000, and the housing 1 clamps the circuit board 2000 and allows the connector 2 and the circuit board 2000 to be disposed therein. In addition, the stackable connector module 1000 of the present application can be stacked with other stackable connector modules 1000 on the upper and lower sides of the housing 1, respectively.

[0069] Next, the housing 1 will be described first, and Figure 5The housing 1 comprises a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are respectively arranged on opposite sides of the circuit board 2000, and the first housing 11 is partially connected to the second housing 12, in other words, the unconnected part is used to sandwich the circuit board 2000.

In detail, the first housing 11 further has a first opening 111, a recess 112, two first track grooves 113, and two first guide blocks 114. The first opening 111 and the recess 112 are formed on the same side of the first housing 11, and the recess 112 is arranged adjacent to the first opening 111. Each of the first track grooves 113 and the first guide blocks 114 is arranged on the left and right sides of the first housing 11, and the first track grooves 113 are formed adjacent to the first guide blocks 114.

It should be noted that the combined structure of the stackable connector module 1000 of the utility model takes two stackable connector modules 1000 as an example, and the number thereof can be adjusted to at most eight structures according to actual connection requirements, which is not limited herein.

[0071] Next, the connector 2 will be described in detail, please refer to Figure 4 , Figure 6 and Figure 7The connector 2 comprises a connector body 21, a plurality of first contacts 22 and a plurality of second contacts 23. The first contacts 22 and the second contacts 23 are arranged adjacently and staggeredly along a first direction D1 on the same side of the connector body 21. In detail, the connector body 21 further comprises a plurality of first slots 211, a plurality of second slots 212, a first eave 213 and a second eave 214. The first slots 211 and the second slots 212 are formed on the same side of the connector body 21 along the first direction D1, and the first slots 211 and the second slots 212 are arranged adjacently and staggeredly, in other words, the upper row is the first slots 211 and the lower row is the second slots 212, and the first slots 211 and the second slots 212 are staggered for corresponding the first contacts 22 and the second contacts 23. In addition, the first eave 213 and the second eave 214 are formed on opposite ends of the connector body 21, the first eave 213 is formed on one end of the connector body 21 close to the first housing 11, and the second eave 214 is formed on one end of the connector body 21 close to the second housing 12. The first eave 213 and the second eave 214 can be tightly engaged with the corresponding holes on the first housing 11 and the second housing 12, respectively. In this embodiment, when the connector 2 is arranged in the first accommodating space S1, the opposite ends of the connector body 21 are accommodated in the first opening 111 of the first housing 11 and the second opening 121 of the second housing 12, respectively, and the first eave 213 and the second eave 214 of the connector body 21 abut against the first opening 111 and the second opening 121, respectively, thereby limiting and fixing the connector 2 in the housing 1. At this time, one end of the first contact 22 is exposed from the first opening 111, and one end of the second contact 23 is exposed from the second opening 121. The exposed first contacts 22 and the exposed second contacts 23 are respectively connected in series with the second contacts 23 and the first contacts 22 of other stackable connector modules 1000.

[0072] As mentioned above, Figure 4 and Figure 6As shown, each of the first contact members 22 further comprises a first fixed segment 221, a first extending segment 222 and a first contact segment 223 connected in sequence. Each of the second contact members 23 further comprises a second fixed segment 231, a second extending segment 232 and a second contact segment 233 connected in sequence. The first extending segment 222 is connected between the first fixed segment 221 and the first contact segment 223. The second extending segment 232 is connected between the second fixed segment 231 and the second contact segment 233. The first fixed segment 221 and the second fixed segment 231 are fixed on the same side of the circuit board 2000 by soldering, wherein the first fixed segment 221 is soldered and fixed at a position of the circuit board 2000 relatively far away from the connector body 21, and the second fixed segment 231 is soldered and fixed at a position of the circuit board 2000 relatively close to the connector body 21. On the other hand, the first extending segment 222 and the first contact segment 223 are correspondingly accommodated in the first embedding groove 211, and the second extending segment 232 and the second contact segment 233 are correspondingly accommodated in the second embedding groove 212. The first contact segment 223 is exposed out of the first opening 111, and the second contact segment 233 is exposed out of the second opening 121, so as to electrically connect the first contact member 22 with the second contact member 23 of another stackable connecting connector module 1000. Similarly, the second contact member 23 can be electrically connected with the first contact member 22 of another stackable connecting connector module 1000. In detail, the first contact segment 223 has a bevel portion 2231 and a flat portion 2232 connected in sequence, and the second contact segment 233 has a curved portion 2331 and a limiting portion 2332 connected in sequence. When different stackable connecting connector modules 1000 are connected, first, the local second contact segment 233 enters the recessed portion 112 of another stackable connecting connector module 1000, and the protruding curved portion 2331 first contacts the bevel portion 2231 of the first contact segment 223 and then abuts against the flat portion 2232, as shown. The bevel portion of the curved portion 2331 of the second contact segment 233 and the bevel portion 2231 of the first contact segment 223 are arranged to guide the mutual interference of the first contact segment 223 and the second contact segment 233, so as to reduce the impact degree and increase the smoothness when the connector modules are connected, and damage is less likely to occur. Figure 13 The bevel portion of the curved portion 2331 of the second contact segment 233 and the bevel portion 2231 of the first contact segment 223 are arranged to guide the mutual interference of the first contact segment 223 and the second contact segment 233, so as to reduce the impact degree and increase the smoothness when the connector modules are connected, and damage is less likely to occur.

[0073] In the embodiment, the limiting portion 2332 of the second contact segment 233 has a T-shaped structure, so as to correspondingly limit the second contact member 23 in the second embedding groove 212, and the contact member is less likely to fall off when the connector modules are connected in the transverse direction.

[0074] It should be noted that the protrusion 122 of the second housing 12 has a first width W1, and each of the second guide blocks 124 of the second housing 12 has a second width W2. In the embodiment, the first width W1 is smaller than the second width W2, as shown. Figure 11In other words, when different connector modules are assembled, the protrusion 122 does not exceed the second guide block 124, so that the friction damage caused by the assembly of the rail groove and the guide block can be avoided. In addition, the exposed second contact 23 does not exceed the protrusion 122, and the recess 112 can be used to protect the protrusion 122 and the second contact 23 from collision damage during assembly. When the stackable connection connector module 1000 is assembled with another stackable connection connector module 1000, the second contact 23 of the other stackable connection connector module 1000 partially extends into the recess 112 of the first housing 11 of the stackable connection connector module 1000 and does not interfere with the first housing 11 of the stackable connection connector module 1000. With the engagement of different stackable connection connector modules 1000, the protrusion 122 of the second housing 12 is engaged in the recess 112 of the first housing 11 of the other stackable connection connector module 1000.

[0075] In summary, the stackable connection connector module of the present application comprises a housing and a connector structure, wherein the circuit board is connected in the middle of the connector and is covered by the housing, and the circuit board is clamped therein. The connector comprises first and second contacts arranged in an upper and lower staggered manner, and part of the contacts are exposed at the opening of the housing and are designed with a beveled structure. This beveled design can guide each other when the modules are engaged, reducing the degree of impact and improving the durability of use. In addition, the stackable connection connector module of the present application significantly enhances the smoothness of the connector module assembly through the cooperation of the rail groove and the guide block, and the combination of the recess and the protrusion. At the same time, the height of the exposed second contact part does not exceed the height of the protrusion on the same side, and the height of the protrusion also does not exceed the first guide block. Such double design can effectively protect the contacts and the connector from damage due to impact during the connection process. Accordingly, the stackable connection connector module of the present application has the function of flexibly stacking and connecting other stackable connection connector modules on both sides thereof, further enhancing its application flexibility and practicality.
