This also facilitates the installation, maintenance, and replacement of wiring, meeting the connection requirements under complex automotive operating conditions. However, traditional automotive connector female connectors have simple sealing structures, making them susceptible to moisture and dust penetration in humid or muddy environments. This accelerates terminal oxidation and corrosion, reducing the lifespan of terminals or wires, leading to signal transmission interruptions or power loss, and affecting the normal operation of the automotive system. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an automotive connector terminal female socket, which solves the technical problem that in the prior art, the traditional terminal female socket has a simple sealing structure, allowing moisture and dust to easily penetrate into the female socket, thereby accelerating terminal oxidation and corrosion, reducing terminal lifespan, and affecting the operation of the automotive system.

[0004] The purpose and function of this utility model for an automotive connector terminal female are achieved by the following specific technical means:

[0005] A female terminal block for an automotive connector includes an outer cover and a mounting base. A limiting mounting portion is provided inside the outer cover. The mounting base passes through the outer cover, with its top end contacting the limiting mounting portion. A plug-in component also passes through the outer cover, its bottom end detachably connected to the mounting base, and multiple sets of female terminals are evenly arranged within the plug-in component. A wiring portion is provided at the end of the mounting base away from the outer cover, containing two sets of wires, each set of wires connected to one of the multiple sets of female terminals. A fixing member is movably fitted onto the outer surface of the outer cover, and an elastic pressing member is provided at its top end, with its bottom end contacting the top end of the outer cover.

[0006] The above technical solution further includes that mounting springs are arranged opposite to each other on both sides of the mounting base, a sliding groove is opened inside the outer cover corresponding to the mounting spring, and a positioning mounting hole is also opened through the outer cover in the sliding groove. The mounting spring is movably arranged in the sliding groove and is locked in the positioning mounting hole.

[0007] The above technical solution further includes that the bottom end of the connector is provided with an installation plate, the top end of the installation plate is in contact with the limiting installation part; the installation plate is also evenly provided with multiple sets of positioning holes, and the top end of the mounting base is provided with multiple sets of clips for the multiple sets of positioning holes, and the multiple sets of clips are respectively disassembled and inserted into the multiple sets of positioning holes.

[0008] The above technical solution further includes that the top of the mounting base is provided with a mounting groove, the mounting groove is provided with an isolation pad, and the top of the isolation pad is in contact with the connector.

[0009] The above technical solution further includes that one end of the conductor is provided with a barrier, and the conductor is secured in the wiring portion of the mounting base by the barrier.

[0010] The above technical solution further includes that multiple sets of positioning and assembly holes are evenly formed inside the plug-in, and an mounting component is also provided on the female terminal, the female terminal being engaged with the positioning and assembly holes of the plug-in through the mounting component.

[0011] The above technical solution further includes that a plug rod is provided at the top of the female terminal and a foldable connector is provided at the other end of the female terminal.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The mounting springs on both sides of the mounting base snap into the positioning mounting holes of the outer cover, and together with the mounting plate and clips, a stable connection of components is achieved. The isolation pads in the mounting groove and the elastic crimping parts on the fixing parts, together with the outer cover, form a multi-layer sealing structure to reduce the intrusion of moisture and dust. The female terminal is fixed to the positioning assembly hole of the plug-in through the mounting parts, and the wires are fixed to the wiring part by the barrier parts to ensure stable electrical connection. At the same time, the barrier parts can prevent impurities from entering along the wire gaps. This not only ensures that all components of the female base are firmly connected and easy to maintain, but also prevents terminal oxidation and corrosion through multi-layer protection, extends service life, and ensures stable operation of the automotive system.

[0014] 2. The bottom mounting plate of the connector has a positioning locking hole that mates with the top locking piece of the mounting base, allowing for a detachable connection. During maintenance, the connector and mounting base can be separated for easy inspection and replacement of the female terminal. The female terminal is inserted into the positioning assembly hole of the connector via the mounting piece, limiting its displacement and ensuring a stable electrical connection. A wiring section is located at the end of the mounting base furthest from the outer casing, where two sets of wires are fixed by a barrier, establishing a connection with the female terminal. The top connector rod of the female terminal is used to mate with the male connector terminal; the other end has a folded connector that connects to the wires, forming a complete electrical path and ensuring stable current signal transmission.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 5As shown, this utility model provides an automotive connector terminal block, including an outer cover 1 and a mounting base 2. A limiting mounting part 101 is provided inside the outer cover 1. The mounting base 2 passes through the outer cover 1, and its top end contacts the limiting mounting part 101. A plug-in 3 is also provided inside the outer cover 1, with its bottom end detachably connected to the mounting base 2. Multiple sets of female terminals 102 are evenly arranged inside the plug-in 3. A wiring part 103 is provided at the end of the mounting base 2 away from the outer cover 1. Two sets of wires 4 pass through the wiring part 103, and the two sets of wires 4 are respectively connected to the multiple sets of female terminals 102. A fixing member 104 is movably sleeved on the outer surface of the outer cover 1. An elastic pressing member 105 is provided at the top of the fixing member 104, and its bottom end contacts the top end of the outer cover 1. The mounting base 2 passes through the outer cover 1, and its top end contacts the limiting mounting part 101, forming an axial positioning support. A fastener 104 is movably fitted onto the outer side of the outer cover 1. The bottom end of the elastic crimping member 105 at the top of the fastener 104 contacts the top of the outer cover 1, pressing the mounting base 2 from the outside with elastic pressure to prevent it from loosening inside the outer cover 1. The bottom end of the plug-in member 3 is detachably connected to the mounting base 2, allowing direct maintenance and replacement of the internal female terminal 102 during inspection, increasing the convenience of device maintenance.

[0025] Multiple sets of female terminals 102 are evenly arranged inside the connector 3. A wiring section 103 is provided at the end of the mounting base 2 away from the outer cover 1. Two sets of wires 4 are threaded through the wiring section 103 and are clamped in the wiring section 103 and connected to the female terminals 102. One end of the female terminal 102 is used to connect with the male terminal, forming a complete electrical transmission path from the male terminal to the wire 4, ensuring stable current or signal transmission. The elastic crimping member 105 at the top of the fixing member 104 outside the outer cover 1 contacts the top of the outer cover 1. When the male terminal passes through the elastic crimping member 105, the elastic crimping member 105 is squeezed and deformed, tightly adhering to the outer wall of the male terminal and the top of the outer cover 1, sealing the gap between the male terminal and the female base, thereby preventing oxidation and corrosion of the female terminal 102.

[0026] like Figure 2 and Figure 4 As shown, a barrier 501 is provided at one end of the conductor 4, and the conductor 4 is secured within the wiring portion 103 of the mounting base 2 by the barrier 501. The barrier 501 secures the conductor 4 within the wiring portion 103 of the mounting base 2, restricting its movement, preventing vibration from causing loosening, and ensuring stable electrical connection. The barrier 501 fills the gap between the conductor 4 and the wiring portion 103, preventing moisture and dust from entering, avoiding oxidation and corrosion of the female terminal 102, and extending its service life. Simultaneously, the barrier 501 bears the tension of the conductor 4, reducing stress at the connection point, lowering the risk of poor contact, and ensuring stable transmission of current or signals.

[0027] like Figures 2 to 4As shown, mounting spring pieces 201 are arranged opposite each other on both sides of the mounting base 2. A sliding groove is formed inside the outer cover 1 corresponding to the mounting spring pieces 201, and a positioning mounting hole 202 is formed through the sliding groove of the outer cover 1. The mounting spring pieces 201 are movably disposed in the sliding groove and engaged in the positioning mounting hole 202. When the mounting base 2 is inserted into the outer cover 1, the mounting spring pieces 201 on both sides are deformed by the pressure of the inner wall of the outer cover 1, retracting and sliding inward along the sliding groove. When the mounting spring pieces 201 move with the mounting base 2 to the position of the positioning mounting hole 202, the spring pieces automatically engage in the positioning mounting hole 202 due to elastic recovery deformation, completing the fixation of the mounting base 2 inside the outer cover 1. For disassembly, press the mounting spring pieces 201 to disengage them from the positioning mounting hole 202, and simultaneously pull the mounting base 2 outward. The mounting spring pieces 201 slide and retract along the sliding groove until the mounting base 2 is completely detached from the outer cover 1, achieving quick disassembly and facilitating later maintenance and repair.

[0028] After the mounting spring 201 engages with the positioning mounting hole 202, a mechanical locking structure is formed, restricting the axial movement of the mounting base 2 within the outer cover 1. This prevents the mounting base 2 from loosening or dislodging along the axis of the outer cover 1 due to vibration. Simultaneously, the engagement of the mounting spring 201 with the positioning mounting hole 202 restricts the radial rotation of the mounting base 2 within the outer cover 1, ensuring a fixed relative position between the mounting base 2 and the outer cover 1. This maintains the overall structural stability of the female base and provides reliable support for internal electrical connections.

[0029] like Figures 3 to 4 As shown, a mounting plate 301 is provided at the bottom of the connector 3, and the top of the mounting plate 301 contacts the limiting mounting part 101. Multiple sets of positioning holes 302 are evenly distributed on the mounting plate 301. Multiple sets of locking elements 303 are provided at the top of the mounting base 2 corresponding to the positioning holes 302. These locking elements 303 are detachable and inserted into the positioning holes 302. The positioning holes 302 on the mounting plate 301 correspond to the locking elements 303 at the top of the mounting base 2. After the locking elements 303 are inserted into the positioning holes 302, the connector 3 is fixed to the top of the mounting base 2, ensuring accurate relative positioning and facilitating the electrical connection alignment between the female terminal 102 and the wire 4. During disassembly, the locking elements 303 are moved out of the positioning holes 302, separating the connector 3 from the mounting base 2 for easy inspection and maintenance of the internal female terminal 102.

[0030] Multiple sets of positioning holes 302 and clips 303 are evenly distributed to form a multi-point fixing structure, dispersing the external forces (such as the force when inserting or removing the male terminal) on the connector 3, and avoiding structural deformation or loosening caused by single-point force. After the clips 303 are inserted into the positioning holes 302, they restrict the axial movement and radial rotation of the connector 3 on the mounting base 2, ensuring that the connector 3 remains in a stable position during the operation of the female base, and maintaining the reliability of the mating between the female terminal 102 and the male terminal.

[0031] like Figure 4As shown, the top of the mounting base 2 is also provided with a mounting groove, and an isolation pad 401 is also provided in the mounting groove. The top of the isolation pad 401 is in contact with the connector 3. The isolation pad 401 is placed in the mounting groove at the top of the mounting base 2, and its top is in contact with the connector 3, filling the gap between the mounting base 2 and the connector 3, preventing moisture and dust from entering the interior of the female base from the connection between the two, and forming a double sealing structure with the elastic pressing member 105. At the same time, when the vehicle vibrates, the isolation pad 401 absorbs the impact force between the connector 3 and the mounting base 2, reducing the relative displacement of the components caused by vibration, and avoiding poor contact at the insertion point of the female terminal 102 and the male terminal due to loosening. The elastic deformation of the isolation pad 401 can also fill the small unevenness of the contact surface between the mounting base 2 and the connector 3, ensuring that the two fit tightly, improving the assembly stability, and at the same time helping to position the connector 3 so that it maintains the correct relative position with the mounting base 2.

[0032] like Figure 3 and Figure 5 As shown, multiple sets of positioning and assembly holes 601 are evenly distributed within the connector 3. A mounting piece 602 is also provided on the female terminal 102, which is secured to the positioning and assembly holes 601 of the connector 3 via the mounting piece 602. A connector rod 701 is provided at the top of the female terminal 102, and a wiring piece 702 is folded at the other end of the female terminal 102. The positioning and assembly holes 601 and the mounting piece 602 adopt a plug-in structure. During assembly, the female terminal 102 can be directly inserted to complete the fixation without additional tools. During disassembly, the mounting piece 602 can be pressed or pried off to detach from the positioning and assembly holes 601, allowing the faulty female terminal 102 to be removed individually. During maintenance, only the damaged female terminal 102 needs to be replaced, without disassembling the entire connector 3, shortening maintenance time and reducing maintenance costs. It also facilitates rapid detection and replacement of female terminals 102 with different functions.

[0033] Multiple sets of positioning and assembly holes 601 are provided in the connector 3, and the shape of the mounting part 602 on the female terminal 102 matches the holes. During installation, the mounting part 602 of the female terminal 102 is aligned and inserted into the positioning and assembly hole 601, which restricts the movement of the female terminal 102 radially and axially. This prevents the female terminal 102 from shaking in the connector 3, ensures that the position of the female terminal 102 is constant, ensures stable insertion with the male terminal, and avoids poor contact caused by displacement.

[0034] Meanwhile, the plug-in rod 701 at the top of the female terminal 102 has an outer diameter that matches the inner diameter of the male terminal, forming a tight contact after being inserted into the male terminal. The other end of the folded connector 702 has a pre-drilled groove for crimping the wire 4, allowing the end of the wire 4 to be placed into the groove and crimped in place. The plug-in rod 701 and the connector 702 form a complete electrical path from the male terminal to the wire 4. The foldable nature of the connector 702 reduces the complexity of the connection and minimizes the bending angle of the wire 4, thereby ensuring the stability of current or signal transmission.

[0035] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
