Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a 14-pin connector for a charging pile module. Background Technology

[0002] A connector, also known as an electrical connector, is an electronic component used to connect or disconnect electrical circuits. It is widely used in various electrical equipment and systems and is a key interface component to ensure circuit continuity, signal transmission, or energy transfer. Its working principle is essentially to make two or more independent electrical circuits conduct through "plugging and unplugging" or "fixed connection" to achieve efficient transmission of current and signals. When it is necessary to disconnect, the circuit can be quickly cut off by separating the mating part of the connector without damaging the original circuit structure. In charging pile modules, connectors can quickly connect power cables to the internal circuits of the module and can be repeatedly plugged and unplugged, which is convenient for later maintenance and replacement.

[0003] However, existing connectors have the following problems when in use:

[0004] Some products have a disorganized internal terminal layout, which can easily cause signal interference and lead to poor transmission stability. They also lack an effective positioning and error prevention structure, which can easily lead to reverse insertion or misalignment during docking, resulting in circuit failure. Furthermore, the terminal connections are not stable enough and may fall off after long-term use or when subjected to vibration. At the same time, the assembly process of some products is cumbersome and the protection performance is limited, making it difficult to fully meet the high requirements of charging pile modules for connection reliability, safety and assembly efficiency.

[0005] This utility model can ensure efficient and stable transmission of electrical energy and signals by standardizing the terminal layout and reducing transmission interference. It also has the functions of preventing errors, preventing interference and preventing detachment, simplifying the assembly process and improving assembly efficiency. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a 14PIN connector for charging pile modules.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a 14PIN connector for a charging pile module, comprising: a lower cover, an upper cover at the upper end of the lower cover, a connecting terminal and a pin terminal embedded between the lower cover and the upper cover, a plurality of connecting tubes fixedly installed at the upper end of the lower cover, the connecting terminals being embedded inside the connecting tubes, a connecting block being fixedly installed on the outermost side of the connecting tube, the pin terminal being embedded inside the connecting block, and a crown spring being fixedly installed inside each connecting tube, the crown spring being matched with the connecting terminal.

[0008] A further preferred embodiment: positioning holes are provided on both the left and right sides of the upper end of the lower cover, and the connecting tube and the connecting block are located between the two positioning holes, with a total of six connecting tubes.

[0009] A further preferred embodiment: The connecting block 1 has a sleeve fixedly installed inside, the number of sleeves is eight, and they are matched with the pin terminals, with the pin terminals embedded inside the sleeves.

[0010] A further preferred embodiment: A lower cover terminal block is embedded in the bottom of the lower cover. The bottom of the lower cover terminal block has a first connection hole and a second connection hole. The number of first connection holes is the same as the number of sleeves, and the first connection holes are nested on the surface of the sleeves. The number of second connection holes is the same as the number of connecting tubes, and they are nested on the surface of the connecting tubes.

[0011] A further preferred embodiment: positioning claws are fixedly installed on both the left and right sides of the front of the top cover, and a top cover terminal block is snapped onto the upper end of the top cover. The front of the top cover terminal block has six through holes, and the through holes are matched with the connecting terminals.

[0012] A further preferred embodiment: A connecting block two is fixedly installed on the right end of the upper cover terminal block, the connecting block two is matched with the pin terminal, and the front of the pin terminal is embedded inside the connecting block two.

[0013] A further preferred embodiment: the upper end of the cover has six through holes, which are matched with connecting terminals. The outermost side of the through holes has eight insertion holes, which are matched with pin terminals.

[0014] A further preferred embodiment: the socket, connecting block two, and connecting block one are all located on the same side.

[0015] Beneficial effects:

[0016] 1. The system is equipped with a connecting block, a connecting tube, and a crown spring. The connecting block allows for the centralized and orderly installation of the pin terminals, and works with the sleeve to ensure the stability of the pin terminal connection. The connecting tube provides an installation carrier for the connecting terminals, enabling their orderly arrangement. The crown spring, in conjunction with the connecting terminals, utilizes its elastic structure to enhance the contact reliability of the connecting terminals, prevent accidental removal, improve the stability and reliability of conductivity, reduce contact resistance, and ensure efficient current transmission. This, in turn, ensures the stable operation of the charging pile module and enhances the durability of the connector, allowing it to maintain good electrical performance even with frequent plugging and unplugging or long-term use, providing strong support for the reliable operation of the charging pile.

[0017] 2. By setting up an upper cover terminal block, a through hole one, and a connecting block two, the upper cover terminal block has a through hole one on the front that matches the connecting terminal, and a connecting block two on the right end that matches the pin terminal. This can protect the upper ends of the connecting terminal and the pin terminal. The independent internal chambers separate the connecting terminals from each other and prevent them from interfering with each other. This layout not only organizes the terminal structure but also reduces signal interference. At the same time, it facilitates the quick docking and assembly of the upper cover terminal block and the upper cover, improves the protection and assembly efficiency of the connector, and ensures the stability and reliability of the signal and power transmission of the charging pile module.

[0018] 3. By setting up positioning claws, it can play a positioning and error prevention role, assisting in achieving accurate docking during the connector docking process, effectively avoiding circuit failures caused by reverse insertion or misalignment, further ensuring the reliability and safety of the connection, and ensuring the stability of power and signal transmission of the charging pile module;

[0019] 4. In summary, this type of charging pile module uses a 14-pin connector, which includes a lower cover, a lower cover terminal block, a first connecting block, a crown spring, an upper cover, an upper cover terminal block, a second connecting block, and positioning claws. The interlocking structure of the lower and upper covers provides a stable mounting foundation for the internal terminals. The lower cover terminal block, through matching holes and precise nesting with connecting tubes and sleeves, enhances the stability of the bottom connection. The first and second connecting blocks are adapted to the corresponding pin terminals, and the connecting tube and crown spring provide limiting protection for the connecting terminals, achieving orderly arrangement and reliable connection of the terminals and reducing transmission interference. The independent chamber design of the upper cover terminal block separates the connecting terminals, providing both protection and anti-interference functions. The positioning claws ensure accurate docking and prevent malfunctions caused by reverse insertion or misalignment. The coordinated operation of these structures simplifies the assembly process, improves assembly efficiency, and enhances connection reliability and safety, ensuring efficient and stable transmission of power and signals from the charging pile module.

[0026] Please see Figure 1-4In this embodiment of the present invention, a 14-pin connector for a charging pile module includes: a lower cover 1, an upper cover 2 disposed on the upper end of the lower cover 1, a connecting terminal 3 and a pin terminal 4 embedded between the lower cover 1 and the upper cover 2, a plurality of connecting tubes 105 fixedly installed on the upper end of the lower cover 1, the connecting terminals 3 being embedded inside the connecting tubes 105, a connecting block 103 fixedly installed on the outermost side of the connecting tube 105, the pin terminal 4 being embedded inside the connecting block 103, and a crown spring 106 fixedly installed inside each connecting tube 105. The crown spring 106 is matched with the connecting terminal 3. Positioning holes 101 are provided on both the left and right sides of the upper end of the lower cover 1. The connecting tube 105 and the connecting block 103 are located between the two positioning holes 101. There are six connecting tubes 105. Eight sleeves 104 are fixedly installed inside the connecting block 103 and are matched with the pin terminal 4. The pin terminal 4 is embedded inside the sleeve 104. A lower cover terminal seat 102 is embedded in the bottom of the lower cover 1. The bottom of the lower cover terminal seat 102 has a connecting hole 107 and a connecting... Hole 2 108, the number of connecting holes 107 is the same as the number of sleeves 104, and connecting holes 107 are nested on the surface of sleeves 104. The number of connecting holes 2 108 is the same as the number of connecting tubes 105, and they are nested on the surface of connecting tubes 105. First, the crown spring 106 is embedded into the six connecting tubes 105 of the lower cover 1 respectively. Then, the pin terminal 4 and the connecting terminal 3 are connected to the upper cover 2. After the connection is completed, the bottom of the pin terminal 4 is aligned with the sleeve 104 in the connecting block 103 on the lower cover 1, and then it is inserted to ensure that the pin terminal and the sleeve are matched and connected. During the process, the bottom of the connecting terminal 3 is aligned with the connecting tube 105 of the lower cover 1, and then inserted downwards to connect the connecting terminal 3 with the crown spring 106. The crown spring 106 restricts the connecting terminal 3 from being pulled out. Then, the lower cover terminal seat 102 is embedded and installed at the bottom of the lower cover 1, so that the connecting hole 107 of the lower cover terminal seat is nested on the surface of the sleeve 104 and the connecting hole 108 is nested on the surface of the connecting tube 105, thus completing the assembly of the entire connector so as to connect to the corresponding interface of the charging pile module. Then, the entire connector is fixed by screws of the same specification through the positioning hole 101.

[0027] In this embodiment of the utility model, positioning claws 201 are fixedly installed on both the left and right sides of the front of the upper cover 2. They mainly play the role of positioning and error prevention. In addition to assisting in the accurate docking of the connector, they can also effectively prevent circuit failures caused by reverse insertion or misalignment, and further ensure the reliability and safety of the connection.

[0028] In this embodiment of the utility model, the upper end of the upper cover 2 is snapped with an upper cover terminal base 202. The upper cover terminal base 202 has six through holes 203 on its front side, and the through holes 203 are matched with the connecting terminals 3. A connecting block 204 is fixedly installed on the right end of the upper cover terminal base 202, and the connecting block 204 is matched with the pin terminal 4. The front of the pin terminal 4 is embedded in the connecting block 204. The upper end of the upper cover 2 has six through holes 205, and the through holes 205 are matched with the connecting terminals 3. Eight insertion holes 206 are opened on the outermost side of the through holes 205, and the insertion holes 206 are matched with the pin terminals 4. When the connecting terminals 3 and the pin terminals 4 are connected to the upper cover 2, the connecting terminals 3 and the pin terminals 4 are first aligned with the through holes 205 and the insertion holes 206 on the upper end of the upper cover 2, respectively, and then the connecting terminals 3 and the pin terminals 4 are connected. Insert the connector 4 downwards in sequence, so that the connecting terminal 3 and the pin terminal 4 pass through the through hole 205 and the insertion hole 206. At this time, the connecting terminal 3 and the pin terminal 4 are both located inside the upper cover 2. The upper cover 2 is hollow. After the connecting terminal 3 and the pin terminal 4 are connected to the upper cover 2, align the upper cover terminal seat 202 with the upper end of the upper cover 2 and push it in from front to back. Align the through hole 203 and the connecting block 204 on the front of the upper cover terminal seat 202 with the connecting terminal 3 and the pin terminal 4 respectively. After pushing in, the upper cover terminal seat 202 will protect the upper end of the connecting terminal 3 and the pin terminal 4 and nest it on its surface. The upper cover terminal seat 202 is an independent chamber. Each connecting terminal 3 is separated from each other, so that the connecting terminals 3 are independent and do not interfere with each other. After the upper cover terminal seat 202 is connected to the upper cover 2, move the entire upper cover 2 downwards and connect it with the lower cover 1.

[0029] In this embodiment of the utility model, the socket 206, the second connecting block 204, and the first connecting block 103 are all located on the same side. By concentrating multiple components connected to the pin terminals on the same side, the structural layout of the connector is simplified, and alignment and connection operations during production and assembly are facilitated. The layout on the same side allows the pin terminals to have a more regular path when transmitting power or signals, reducing interference, improving the stability and reliability of the connection, and ensuring that the power or signal of the charging pile module can be transmitted efficiently.
