Description

Technical Field

[0001] This utility model relates to connectors between vehicle-mounted devices, and in particular to sockets that constitute electrical connectors. Background Technology

[0002] Electrical connectors inside electric vehicles are used to establish electrical connections between batteries, chargers, charging ports, and electrical devices, as well as between circuit control equipment and electrical components. Most electrical connectors use a combination of wire harnesses, busbars, and terminals for their input and output conductors, depending on the connection requirements of various devices. The connection methods for the input and output conductors of electrical connectors fall into two categories: one where the connection is achieved within a single housing, and the other where the connection is achieved within a male and female housing. Electrical connectors using the male-female connection method are divided into plugs and sockets, such as the connectors disclosed in Chinese patent documents CN222463652U and CN221928780U. When the plug is removed from the socket, the socket terminals are exposed. If a person or tool accidentally touches the terminals, it can cause an electric shock hazard. Therefore, an insulating cap is installed on the end face of the socket terminal connection to prevent electric shock. Because the end face loses its conductivity, conductivity can only be achieved through the side of the end. This means that the connection end of the socket terminal can only use male pins to interlock with the female end of the plug wire harness. The gap between the male pin and the female end inevitably results in gaps, easily leading to poor contact, poor and unstable conductivity. Summary of the Invention

[0003] In order to overcome the defects of the prior art where the terminal insulating caps force the input and output conductors to use male and female plugs, resulting in poor and unstable conductive contact, this utility model proposes an electrical connector socket that can replace the insulating caps to provide protection against electric shock while effectively improving conductivity and simplifying the structure of the input and output conductors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an electrical connector socket, including a base, a pair of shafts for inserting terminals are provided at the base of the base, an inner shell extends from the front of the base, the inner shell surrounds the shafts, and the base is provided with a soft body for blocking or avoiding the terminals.

[0005] Furthermore, the rear part of the base extends into a cavity, and a spring is placed inside the cavity; a bracket is provided between the two shaft cylinders, the bracket passes through the base and abuts against the spring, and the bracket supports a soft body for blocking or avoiding the terminal.

[0006] Furthermore, a slit is opened in the side wall of the inner shell, and correspondingly, a protrusion is provided on the side of the bracket, which is inserted into the slit.

[0007] Furthermore, the two shafts, together with the base and the inner shell, form a cavity that accommodates the support and the soft body.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: by adding a soft body to the base, the soft body shields the terminals to prevent electric shock, thereby improving the safety of the socket. The use of a soft body instead of an insulating cap eliminates the need to design the terminals as male pins, realizing contact conductivity between the socket terminals and the plug busbar. This non-male-female plug-in contact conductivity can be achieved by using a threaded connection, which improves the stability of conductivity and the firmness of the connection. Furthermore, it simplifies the structure of the terminals and reduces the difficulty of terminal design. Attached Figure Description

[0012] Figure 4 This is a schematic diagram showing the soft housing of the electrical connector socket inside the cavity. Detailed Implementation

[0013] To better understand the purpose, features, and advantages of this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate this utility model.

[0014] like Figure 1 and Figure 2 As shown, the socket consists of a base 1, terminals 2, a flexible body 3, a bracket 4, a spring 5, and a cover 6. The base 1 is made of a single piece and consists of a base 1.1, an outer shell 1.2, an inner shell 1.3, a shaft 1.5, and a cavity 1.4.

[0015] The front of the base 1.1 extends into an outer shell 1.2 and an inner shell 1.3. The inner shell 1.3 surrounds a pair of shaft sleeves 1.5, which are tangential to the inner wall of the inner shell. The shaft sleeves 1.5 pass through the base 1.1 and are used to insert terminals 2. The distance between the two shaft sleeves 1.5, the inner shell 1.3, and the base 1.1 forms a cavity 1.6. The cavity 1.6 provides space for the support 4 and accommodates the support 4 and terminals 2. Terminals 2 are inserted into the shaft sleeves 1.5. A cover 6 closes the port of the shaft sleeves 1.5 and secures the terminals 2. The rear of the base 1.1 extends into a cavity 1.4, which accommodates one end of a spring 5. The other end of the spring 5 abuts against the support 4, which passes through the middle of the base 1.1. A slit 1.7 is formed in the side wall of the inner shell 1.3, falling into the cavity 1.6.

[0016] like Figure 3As shown, the side of the bracket 4 has a protrusion 4.1, which fits into the gap of the inner shell 1.3. The middle of the bracket has a groove 4.2, which holds the spring 5. The front end of the bracket 4 has a protrusion 4.3. The bracket 4 supports the soft body 3, which can bend and deform under external force. The soft body is made of rubber material and has a planar structure. The middle of the soft body 3 has a through hole 3.1, which fits into the protrusion 4.3 of the bracket 4.

[0017] like Figure 1 As shown, when the socket is in an idle state, the bracket 4 supports the flexible body 3, which is in a flat state. The flexible body 3 covers the cavity 1.6 and the terminal 2, thus preventing foreign objects from entering and also preventing electric shock caused by fingers touching the terminal. When the socket needs to be plugged in, the protrusion A of the plug presses against the middle part of the flexible body 3, forcing the flexible body 3 to deform inward (indent) and be inserted into the cavity 1.6, so that the flexible body 3 avoids the end face of the terminal 2, leaving the end face of the terminal 2 exposed. After the socket and plug are plugged in, the flexible body remains retracted inside the cavity 1.6. Figure 4 As shown. When the plug is disconnected, the spring 5 pushes the bracket 4 to extend outward, and the soft body 3 is exposed outside the cavity 1.6 under the action of the bracket 4. The soft body deforms (stretches) outward and returns to a flat state.
