Figures 1 to 5As shown, in one embodiment of the present invention, a line end female connector is provided, comprising a female housing 1, an electrical connection component 2 and a fixing element 3, the female housing 1 comprising a plug-in portion 11, a fixing portion 12 and a wiring portion 13 arranged in sequence, the plug-in portion 11 being provided with a plug-in cavity 111, a plug-in sleeve 112 being provided on the plug-in cavity 111, a placement cavity 113 being provided in the plug-in sleeve 112, one end of the placement cavity 113 being passed through to the wiring portion 13, the electrical connection component 2 being provided in the placement cavity 113, and one end extending toward the plug-in cavity 111, a side slot 121 being provided on one side of the fixing portion 12, one end of the side slot 121 being connected to the placement cavity 113, the fixing element 3 being provided in the side slot 121, and fixing the electrical connection component 2 in the placement cavity 113. This embodiment ensures the precise positioning of the electrical connection component 2 within the female housing 1 by combining the plug sleeve 112 with the placement cavity 113, effectively preventing poor contact or disengagement caused by vibration or external forces, and significantly improving the overall stability and reliability of the connector. The direct connection between the wiring portion 13 and the placement cavity 113 makes the installation of the electrical connection component 2 more direct and quick, eliminating the need for a complex assembly process, reducing operational difficulty and improving work efficiency. At the same time, this design also facilitates subsequent maintenance or replacement of the electrical connection component 2. The plug-in portion 11, fixing portion 12, and wiring portion 13 of the female housing 1 are arranged in sequence, which not only ensures the compactness of the overall structure of the connector, but also effectively saves installation space, making it suitable for various compact electronic devices or systems, and enhancing the product's applicability and flexibility. The lateral slot 121 of the fixing portion 12, in conjunction with the fixing element 3, ensures the secure fixation of the electrical connection component 2. This lateral fixing method not only enhances the connector's pull-out resistance, but also avoids the assembly interference problems that may arise from traditional axial fixing, further improving the connector's performance.

[0026] The wall of the plug-in cavity 111 is provided with a plug-in positioning strip 114, and the top of the plug-in cavity 111 is provided with a plug-in fixing slot 115. Specifically, a positioning mounting platform 116 is provided on the lower side of the plug-in portion 11, and a positioning slide 117 is provided on the positioning mounting platform 116 for fixing the plug-in portion 11. The plug-in cavity 111 is provided with a reinforcement portion 1111, and the plug-in sleeve 112 is provided on the reinforcement portion 1111. A connecting strip 1112 is provided on one side of the reinforcement portion 1111, and one end of the connecting strip 1112 is connected to the wall of the plug-in cavity 111. In this embodiment, the plug-in positioning strip 114 provided on the wall of the plug-in cavity 111 ensures that the plug-in portion 111 can be accurately aligned during the insertion process, effectively reducing assembly errors and improving overall assembly efficiency and accuracy. At the same time, the top plug-in fixing slot 115 acts as a secondary locking mechanism, further enhancing the fixing effect of the plug-in portion 11, preventing accidental disengagement and ensuring the stable transmission performance of the connector under complex working conditions. The positioning mounting platform 116 on the lower side of the plug-in portion 11 and the positioning slot 117 thereon not only simplify the installation process, but also guide the plug-in portion 11 smoothly into place through the guiding effect of the slot, achieving fast and reliable fixing. The provision of the reinforcement portion 1111 enhances the structural strength of the plug-in sleeve 112 and improves the connector's ability to withstand external forces.

[0027] The lateral slot 121 is provided with a fastening clip 1211, one end of which extends into the housing cavity 113. The fastening clip 1211 is used to cooperate with the fixing element 3 to secure the power connection assembly 2 within the housing cavity 113. Specifically, mounting slots 1212 are provided on both sides of the lateral slot 121. Mounting clips 31 are provided on both sides of the fixing element 3. The mounting clips 31 are used to cooperate with the mounting slots 1212 to secure the fixing element 3 to the lateral slot 121. In this embodiment, one end of the fastening clip 1211 extends deeply into the housing cavity 113, which not only effectively locks the power connection assembly 2 in place, preventing it from loosening or falling out due to vibration or external forces, but also ensures the reliability and security of the electrical connection. Furthermore, by providing mounting slots 1212 on both sides of the lateral slot 121 and cooperating with the mounting clips 31 on the fixing element 3, a quick and secure fixing method is achieved, simplifying the installation process and improving assembly efficiency. This structural design not only optimizes the overall structural strength of the connector, but also facilitates subsequent maintenance and replacement operations. When the power supply assembly 2 needs to be replaced, it can be easily completed by simply releasing the fastening clip 1211 and disconnecting the installation clip 31 from the slot, greatly reducing maintenance costs and time.

[0028] The fixing element 3 is provided with a fixed pressure block 32, and the fixed pressure block 32 extends toward the placement cavity 113 to press and fix the power connection component 2 on the placement cavity 113. In this embodiment, the fixed pressure block 32 extends precisely toward the placement cavity 113, and the uniform pressure exerted by it effectively ensures the tight fit between the power connection component 2 and the placement cavity 113, avoiding the problem of looseness or poor contact caused by vibration or external force. This design not only simplifies the installation process and improves assembly efficiency, but also significantly reduces the risk of electrical failure caused by poor contact. At the same time, the use of the fixed pressure block 32 enhances the overall structural strength of the connector and extends the service life of the product. The wiring portion 13 includes a wiring boss, and the wiring boss is provided with a wiring hole, one end of which is connected to the placement cavity 113. In this embodiment,

In this embodiment, the power connection sleeve 21 is firmly placed in the placement cavity 113 inside the connector, ensuring the stability and positioning accuracy of the entire power connection structure, and effectively preventing loosening or displacement caused by vibration or external force. The built-in insulator 22 not only isolates the power connection terminal 23 from direct contact with the outside world, significantly improving electrical safety, but also prevents current leakage and short circuit risks, ensuring the reliability of equipment operation. The power connection terminal 23 is precisely set in the insulator 22, which not only facilitates the rapid and accurate connection with the external power supply or signal line, but also reduces the impact of the external environment on the contact performance through the protection of the insulation layer. The careful layout of the connecting wire 24 has one end tightly connected to the power terminal 23, which enables smooth transmission of electrical signals or currents, while the other end can be flexibly configured as needed, enhancing the versatility and scalability of the connector.

[0030] The power connection sleeve 21 is provided with a constricted portion 211, and the fixing element 3 fixes the constricted portion 211 in the placement cavity 113; a limiting clip 212 is provided on the side of the power connection sleeve 21 close to the constricted portion 211, and the placement cavity 113 is provided with a limiting slot. The limiting clip 212 is used to cooperate with the limiting slot to limit the position of the power connection sleeve 21 in the placement cavity 113. In this embodiment, the design of the constricted portion 211 not only optimizes the compactness of the structure, but also ensures that the power connection sleeve 21 can remain stable under vibration or external force through the precise cooperation of the fixing element 3, effectively reducing the risk of connection failure. In addition, the limiting clip 212 and the limiting slot in the placement cavity 113 form a precise alignment mechanism. This design further limits the axial and circumferential movement of the power connection sleeve 21 in the placement cavity 113, achieving precise positioning and reliable locking.

[0031] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
