Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and specifically relates to an improved electrical connector. Background Technology

[0002] A pluggable electrical connector is a device that achieves electrical connection by plugging and unplugging a connector into a socket. This type of connector plays a crucial role in electronic equipment, facilitating connections and communication between devices. Existing pluggable electrical connectors typically have terminals embedded in the connector, and corresponding inserts or pins embedded in the socket. For the terminals in the connector, the operator usually inserts the terminal and hears a "click," indicating that the terminal is properly engaged with the connector. However, in actual installation, due to differences in operator experience, external noise levels, or factors such as mood or fatigue, misjudgment by sound can occur. Since most operators are unfamiliar with the internal structure of the connector, they may misjudge the connection, sometimes not actually engaging, or requiring two or more clicks as the terminal is inserted. This leads to a certain probability of misjudging the connection by sound alone. Such misjudgments can result in potential problems such as terminals accidentally dislodging, circuit malfunctions, equipment damage, or even electric shock.

[0003] Meanwhile, some existing connector structures have recessed grooves on both edges to prevent reverse insertion when mating with the connector socket. These grooves allow the user to observe the fit of the two edge terminals within the connector. However, in most cases, multiple terminals are installed within the connector, meaning the user or operator can only check the two edge terminals during installation. Therefore, there is an urgent need for a pluggable electrical connector that ensures a secure connection between the terminals and the connector, and guarantees against reverse insertion after installation. Utility Model Content

[0004] The purpose of this utility model is to provide a reasonably structured electrical connector with an observation window that allows users to directly observe the installation status of the terminals, thereby promptly correcting any improper terminal installation and ensuring the reliability of the terminal installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an improved electrical connector, including a plug and terminals. The plug has multiple terminal mounting cavities and a plug interface communicating with each terminal mounting cavity. The terminals are installed in the terminal mounting cavities and have a snap-fit ​​part that is positioned and connected to the plug. There are multiple terminals. The surface of the plug also has an observation window corresponding to each terminal mounting cavity. The observation windows are communicating with the terminal mounting cavities and are arranged in a row. The snap-fit ​​part on the terminal is opposite to the position of the observation window. The plug has a locking part formed on its exterior for locking and engaging with a plug socket.

[0007] Preferably, the observation window is a through groove on the connector relative to the arrangement position of the terminals. The through groove is connected to the terminal mounting cavity. An abutment block is formed in the through groove. The abutment block abuts against the snap-fit ​​part to position the terminal in the connector.

[0008] Preferably, a plug guide block is formed on one side of the plug.

[0009] Preferably, the terminal mounting cavity includes a terminal insertion inlet extending to one end of the connector and a bottom port extending to the other end of the connector. The insertion interface is distributed on the other end of the connector and communicates with the bottom port. The through groove includes a first groove wall and a second groove wall sequentially distributed from the terminal insertion inlet to the bottom port. One end of the abutment block is connected to the first groove wall, and the other end of the abutment block and the second groove wall form a terminal limiting space for the snap-fit ​​portion on the terminal to abut against the abutment block.

[0010] Preferably, a locking element is also formed on the outside of the connector, and the locking element is connected to the outside of the connector via a connecting block. The locking element includes a press-to-unlock end extending to the outside of the terminal inlet and a locking end extending toward the connector. The other end of the connecting block, which is connected to the outside of the connector, is distributed between the two ends of the locking element and forms a lever structure. One end of the locking part is connected to the locking end, and the other end faces the connector.

[0011] The advantages of this invention are as follows: By providing an observation window on the connector, and designing the observation window to allow for connection between the plug mounting cavity and the terminal mounting cavity, the alignment of the terminals inserted into the connector can be visually observed through the observation window. This allows for timely correction of any improper terminal installation, ensuring reliable terminal installation. Furthermore, the locking mechanism on the connector ensures reliable locking after mating with the socket, further guaranteeing the reliability of the connector's installation and use.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figure 1-6As shown, the electrical connector of this utility model embodiment includes a plug 1 and terminals (not shown in the figure); the plug is used to be inserted into a socket, the plug 1 has a plurality of terminal mounting cavities 4 and a plug interface 5 communicating with each terminal mounting cavity 4, the terminal is installed in the terminal mounting cavity 4 and has a snap-fit ​​part that is positioned and connected to the plug 1, specifically the snap-fit ​​part is a protrusion formed on the terminal; there are a plurality of terminals, the surface of the plug 1 is also provided with an observation window 3 corresponding to each terminal mounting cavity 4, the observation window 3 is connected to the terminal mounting cavity 4, and all the observation windows 3 are arranged in a row, the snap-fit ​​part on the terminal is opposite to the observation window 3, so that the engagement status of the snap-fit ​​part 7 can be seen through the observation window 3; the plug 1 has a locking part 24 formed on the outside for locking with the socket. In this embodiment, an observation window 3 is provided on the connector 1. The observation window 3 is designed to allow visualization between the plug mounting cavity and the terminal mounting cavity. This allows for direct inspection of the terminal mounting status during product quality checks, enabling timely correction of any improper terminal mounting and ensuring the reliability of the terminal mounting. Simultaneously, the locking part 24 on the connector 1 ensures reliable locking after the connector 1 engages with the external socket, thereby guaranteeing the reliability of the electrical connector installation and use.

[0023] like Figure 1-2 As shown in Figures 5-6, the observation window 3 is a through groove on the connector 1 relative to the arrangement of the terminals. The through groove is connected to the terminal mounting cavity 4. An abutment block 33 is formed in the through groove. The abutment block 33 abuts against the snap-fit ​​part to position the terminal in the connector 1. The design of the abutment position of the terminal on the connector 1 being clearly visible in the through groove position can further ensure the reliability of the installation of the terminal inserted into the connector 1. At the same time, it also ensures the reliability of the design of the observation window 3. That is, after the terminal is installed in the connector 1, it can be intuitively distinguished by the position of the observation window 3 whether the terminal is installed in place, thereby ensuring the reliability of the design of the connector 1.

[0024] like Figure 3-4 As shown, a plug guide block 6 is formed on one side of the outside of the plug 1. Correspondingly, a plug guide groove adapted to the plug guide block 6 is formed on the plug socket. The plug guide block 6 and the plug guide groove form a reverse insertion stop between the plug 1 and the plug socket. During the plugging process, the plug 1 and the plug socket will not be plugged in reverse.

[0025] like Figure 1-2As shown in Figures 5-6, the terminal mounting cavity 4 includes a terminal inlet 42 extending to one end of the connector 1 and a bottom port 41 extending to the other end of the connector 1. The connector 5 is distributed on the other end of the connector 1 and communicates with the bottom port 41. The through groove includes a first groove wall 31 and a second groove wall 32 sequentially distributed from the terminal inlet 42 to the bottom port 41. One end of the abutment block 33 is connected to the first groove wall 31, and the other end of the abutment block 33 is between the second groove wall 32 to form a terminal limiting space for the snap-fit ​​portion on the terminal to abut against the abutment block 33. This design allows the abutment block 33 used for terminal limiting to be reliably distributed at the position of the observation window 3 when the terminal is limited at the position of the observation window 3. This avoids the situation where the terminal limiting is affected by the unreliable design of the plug after the observation window 3 is involved.

[0026] like Figure 1-6 As shown, a locking element 2 is also formed on the outside of the connector 1. The locking element 2 is connected to the outside of the connector 1 by a connecting block 23. The locking element 2 includes a press-to-unlock end 21 extending to the outside of the terminal inlet 42 and a locking end 22 extending towards the connector. The other end of the connecting block 23, which is connected to the outside of the connector 1, is distributed between the two ends of the locking element 2 and forms a lever structure. One end of the locking part 24 is connected to the locking end 22, and the other end faces the connector 1. This design ensures that the connector 1 and the connector socket are reliably locked after they are plugged in. When it is necessary to separate the connector 1 from the connector socket, the locking end 22 is released from the lock by pressing the press-to-unlock end 21 on the locking element 2.

[0027] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the scope of protection of this invention.
