[0002] Connectors are indispensable in the connection of electrical equipment. Connectors are a type of connector that connects terminals and wiring harnesses. Traditional connectors have a female head and a male head that mates with the female head. A socket is provided at the female head to facilitate docking with the male head.

[0003] Currently, most female connector jacks are fixed together with male connectors through interference fit when plugged in. As a result, after long-term use of the connector, the tightening force at the interface will gradually weaken over time, resulting in looseness and poor contact. Utility Model Content

[0016] The present invention will be described in further detail below with reference to the accompanying drawings.

[0017] This embodiment discloses a female jack of a crimp connector, such as Figures 1 to 3As shown, it includes a hollow plug-in sleeve 1 formed by stamping and rolling a plate, and a plug-in end 2 extending from one end of the plug-in sleeve 1 and mating with a male plug; the plug-in end 2 includes a closing opening 22 and an elastic groove 21, and the plug-in end 2 is used to connect the male pin of the plug, and the male pin enters from the plug interface. Because the closing opening 22 and the elastic groove 21 are provided, the plug interface can clamp the male pin after the male pin is connected to the plug-in end 2 to obtain a better connection state. The other end of the plug-in sleeve 1 includes a terminal 3 connected to the power cord, and the terminal 3 includes an arc-shaped bottom plate 31. The arc-shaped bottom plate 31 is sequentially provided with blades extending upward and bending inward, a dividing groove, and a connecting plate from the terminal 3 to the plug-in end 2; the closing opening 22 is provided with a flexible elastic sheet 221, and the flexible elastic sheet 221 enters the inner side through the elastic groove 21 and extends continuously inward along the inner wall of the opposite side closing 22 to the next elastic groove 21; when the plug pin is inserted into the plug end 2, the flexible elastic piece 221 will deform to a certain extent, so that it can assist in clamping the pin, so that the new model is not easy to loosen after insertion. The flexible elastic piece 221 is symmetrically arranged with the center of the insert tube 1 as the axis. The symmetrical flexible elastic piece 221 makes the elastic force received by the inserted pin tightened evenly, and the symmetrical flexible elastic piece 221 can form a clamping mechanism that tightens as the closing 22 expands. When the closing 22 expands, the symmetrical flexible elastic pieces 221 will approach the central axis of each other under the drive of the expansion of the closing 22, so that the mechanism formed by the symmetrical flexible elastic pieces 221 can be clamped.

[0018] Further improvement, the closing opening 22 is formed by the gradual reduction in diameter of the plug end 2 relative to the insert 1. The diameter of the closing opening 22 at the end is expanded to form a trumpet-shaped interface. The slowly shrinking socket can firmly clamp the male plug when it is connected, ensuring good contact between the male and female plugs. The expanded trumpet-shaped interface allows a larger diameter access hole when the male plug is connected, making the connection process simple and convenient. The trumpet-shaped interface is linearly smaller than the diameter of the insert 1. When installing this new type of connector, the trumpet-shaped interface can smoothly enter and pass through the mounting hole set in the socket, without causing unnecessary obstruction to the installation process.

[0019] Further improvements are made to the flexible elastic sheet 221, which extends from the closing opening 22 toward the plug end 2 to the bottom of the elastic groove 21. The extended flexible elastic sheet 221 amplifies the tightening effect brought about by the enlargement of the closing opening 22, so that even when the closing opening 22 is somewhat loose during use, it still has a good tightening effect and electrical contact. The flexible elastic sheet 221 forms an angle with the inner wall of the interface. The angle between the flexible elastic sheet 221 and the inner wall increases the contact surface between the inserted pin and the flexible elastic sheet 221, thereby improving the electrical contact of the new type. When the pin is inserted into the new type, the setting of the angle creates a transitional slope between the flexible elastic sheet 221 and the pin, so that the flexible elastic sheet 221 does not hinder the insertion of the pin.

[0020] Further improvement, the terminal 3 is provided with a cylindrical tube 32, which is coaxial with the insert tube 1 and has a diameter larger than that of the insert tube 1. The radius of the arc bottom plate 31 is equal to that of the cylindrical tube 32. A step can be formed between the cylindrical tube 32 and the insert tube 1. When installing the new type of device, the installation position of the new type of device can be determined by adapting to the step.

[0021] Further improvements include the outwardly bent protrusion 11 on the side wall of the insert 1. When stressed, the protrusion 11 contracts inward, and when unstressed, it returns to its original position. This allows the new device to return to its original position after installation, preventing it from slipping out of the socket. By providing a step between the cylindrical tube 32 and the insert 1 in the socket mounting hole, and a stopper corresponding to the protrusion 11, the depth of the installed position can be controlled, ensuring stability and preventing it from slipping out. The protrusion 11 is connected to the side wall of the insert 1 facing the plug end 2, and a transition slope 111 is provided at the connection. The provision of the transition slope 111 ensures that the new device can be smoothly inserted into the socket during installation without being hindered by the stopper provided within the socket.

[0022] Further improvement, the protrusions 11 are symmetrically arranged with the center of the insert 1 as the symmetrical center, thereby improving the load-bearing capacity of the present invention, making the force evenly distributed, and reducing vibration caused by unbalanced force during use.

[0023] Working principle of the utility model

[0024] After confirming that the new type is reliably connected to the power cord, the new type is installed into a matching socket. Because the outer diameter of the trumpet-shaped interface is smaller than the outer diameter of the plug 1, the process of installing the new type of connector into the socket is very smooth. When the surface of the cylindrical tube 32 contacts the surface of the socket, a sound of the protrusion 11 opening can be heard, indicating that the new type has been firmly and reliably installed.

[0025] After the installation is completed, the plug terminal can be inserted from the plug end 2. The electrical contact of the new type is increased by setting a symmetrical flexible elastic sheet 221 starting from one side of the closing opening 22 and extending to the opposite side and continuously extending along the inner wall of the opposite plug end. The symmetrical flexible elastic sheet 221 forms a clamping mechanism. When the closing opening 22 of the speaker is expanded and the connection is loose during use, the deformation of the flexible elastic sheet 221 increases and the tightening force becomes larger. The flexible elastic sheet increases the electrical contact, reduces the occurrence of looseness and poor contact, and improves the service life.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
