[0002] In the field of electronic connector manufacturing, strip connectors, with their compact structure and stable connection, are widely used in various electronic devices, playing a crucial role in the stable transmission of circuit signals. However, serious problems have been exposed in the actual production and use of strip connectors. Although they are designed with a foolproof mounting structure to prevent incorrect insertion and improve assembly accuracy and convenience, uneven glue thickness occurs at the foolproof mounting structure due to factors such as mold precision and injection molding process parameter control during actual production. This uneven glue thickness distribution easily leads to product deformation and twisting. As a critical component, the plastic insulation body of the connector changes with the overall deformation of the connector, which seriously affects the electrical and mechanical properties of the connector, leading to potential problems such as poor contact and insulation failure. This greatly reduces the reliability and stability of the product, making it impossible for the strip connector to meet the stringent requirements of product quality consistency and stability in mass production.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] This application incorporates a foolproof mounting bracket on the plastic insulating body, with protruding positions and structural through holes on the bracket. The thickness of the protruding positions can be adjusted according to the deformation of the plastic insulating body, effectively controlling the deformation of the foolproof mounting bracket. Simultaneously, multiple evenly distributed structural positions are provided at the bottom of the plastic insulating body, and the structural positions, protruding positions, and structural through holes are integrally formed on the plastic insulating body. Therefore, the deformation of the plastic insulating body is limited by the thickness of the structural positions, protruding positions, and structural through holes. By adjusting the thickness of the structural positions, protruding positions, and structural through holes as a whole according to the deformation of the plastic insulating body, the overall deformation of the plastic insulating body can be controlled more effectively, thereby improving the reliability and stability of the electrical connector.

[0023] Example 1

[0024] Combining 1 and Figure 2 As shown, this utility model embodiment provides an electrical connector, including a plastic insulating body 1, a conductive terminal 2 and a fixing piece 3 housed in the plastic insulating body 1. The plastic insulating body 1 includes a foolproof mounting bracket 11, which includes a protruding part 110 and a structural through hole 111 located below the protruding part 110. The bottom of the plastic insulating body 1 includes multiple sets of evenly distributed structural positions. The structural positions, the protruding part 110 and the structural through hole 111 are integrally formed. The deformation of the plastic insulating body 1 is limited by the thickness of the structural positions, the protruding part 110 and the structural through hole 111.

[0025] In this embodiment, the insulating body of the electrical connector is a plastic insulating body 1. The plastic insulating body 1 possesses certain elastic properties. Based on the structural limitations and positional settings on the plastic insulating body 1, it can withstand a certain degree of deformation, improving the yield rate of the electrical connector and giving it stronger reliability and stability. Current transmission is achieved through conductive terminals 2. The conductive terminals 2 are housed within the plastic insulating body 1. Wrapping the conductive terminals 2 with a high-insulation material prevents signal or current interference between terminals, ensuring electrical safety and signal stability. A fixing piece 3 is connected to the plastic insulating body 1. The fixing piece 3 can be firmly fixed to the plastic insulating body 1 by means of clips, screws, or welding, thus securing the plastic insulating body 1 and facilitating the installation of the electrical connector with other mounting structures.

[0026] Furthermore, at least one anti-misfit mounting bracket 11 can be provided on the plastic insulating body 1; in this embodiment, two anti-misfit mounting brackets 11 are provided. Providing anti-misfit mounting brackets 11 on the plastic insulating body 1 can prevent incorrect insertion, which could lead to equipment damage, circuit failure, and safety hazards, thus improving the accuracy and safety of insertion. The anti-misfit mounting bracket 11 includes a protruding part 110 and a structural through hole 111. The protruding part 110 can be square, arc-shaped, etc. The structural through hole 111 is located directly below the protruding part 110 and within the cavity of the plastic insulating body 1, penetrating the bottom of the plastic insulating body 1. The thickness of the protruding part 110 can be adjusted according to the deformation of the plastic insulating body 1 to control the amount of deformation, thereby reducing the overall deformation of the electrical connector. For example, when the deformation of the plastic insulating body 1 increases, the thickness of the protruding part 110 is increased; when the deformation of the plastic insulating body 1 is small, the thickness of the protruding part 110 is decreased or maintained at a preset baseline. The deformation of the plastic insulating body 1 can be determined by methods such as displacement measurement and strain modulus calculation. Furthermore, a data relationship can be established between the deformation of the plastic insulating body 1 and the thickness of the protruding part 110 to achieve precise thickness adjustment.

[0027] Furthermore, multiple sets of evenly distributed structural positions can be provided at the bottom of the plastic insulating body 1. The structural positions, protrusions 110, and structural through holes 111 are integrally formed. Based on the plastic material, the structural positions also have elastic properties. Therefore, the thickness of the structural positions can be adjusted according to the deformation of the plastic insulating body 1. For example, if the deformation of the plastic insulating body 1 is greater than a preset value, the thickness of the structural positions is increased. Optionally, the position of the structural positions, or both the position and thickness of the structural positions, can also be adjusted. For example, if the deformation of the plastic insulating body 1 is greater than a preset value, the distribution density and thickness of the structural positions are increased.

[0028] In some optional embodiments, a mathematical relationship can be established between the deformation of the plastic insulating body 1 and the structural positions, protrusions 110, and structural through holes 111. This is more conducive to the precise estimation and adjustment of the thickness of the structural positions, protrusions 110, and structural through holes 111 based on the actual deformation of the plastic insulating body 1 during the testing process before production, with the deformation of the plastic insulating body 1 as the optimization target. This allows for precise adjustment of the deformation of the plastic insulating body 1 by combining the structural positions, protrusions 110, and structural through holes 111, thereby achieving optimal control of the overall deformation of the electrical connector.

[0029] In this embodiment of the invention, by providing a foolproof mounting bracket 11 on the plastic insulating body 1, damage to equipment, circuit failures, and safety hazards caused by mis-insertion can be prevented, thereby improving the accuracy and safety of the connection. The protruding part 110 and the structural through hole 111 allow for adjustment of the thickness of the protruding part 110 according to the deformation of the plastic insulating body 1, effectively controlling the deformation of the foolproof mounting bracket 11. Simultaneously, multiple sets of evenly distributed structural positions are provided at the bottom of the plastic insulating body 1, and the structural positions, protruding parts 110, and structural through holes 111 are integrally formed on the plastic insulating body 1. Therefore, the deformation of the plastic insulating body 1 is limited by the thickness of the structural positions, protruding parts 110, and structural through holes 111. By adjusting the thickness of the structural positions, protruding parts 110, and structural through holes 111 as a whole according to the deformation of the plastic insulating body 1, the overall deformation of the plastic insulating body 1 can be controlled more effectively, thereby improving the reliability and stability of the electrical connector.

[0030] Example 2

[0031] Combination Figure 1 and Figure 2 As shown, in some optional embodiments, the plastic insulating body 1 includes anti-foolproof hanging platforms 11 symmetrically arranged at both ends of the plastic insulating body 1. The protrusion 110 of each anti-foolproof hanging platform 11 extends inward from the upper side of the cavity edge of the plastic insulating body 1. The structural through hole 111 is provided at the bottom of the cavity edge of the plastic insulating body 1, and the protrusion 110 is directly opposite the structural through hole 111.

[0032] In this embodiment, a foolproof mounting bracket 11 can be set on the same side at both ends of the plastic insulating body 1. During the assembly process, the operator can quickly identify the correct assembly direction, avoiding assembly errors caused by confusion of direction. For example, on an automated assembly line, a robotic arm can accurately grasp and place the electrical connector based on the specific position of the foolproof mounting bracket 11, greatly improving the accuracy and efficiency of assembly. Moreover, the two foolproof mounting brackets 11 cooperate with each other, so even if one bracket is slightly disturbed or damaged during the assembly process, the other bracket can still play its foolproof role, ensuring that the electrical connector is not assembled in the wrong way.

[0033] Furthermore, the protrusion 110 on each anti-misalignment bracket 11 extends from the upper side of the cavity edge of the plastic insulating body 1 toward the inner side of the cavity, which can enhance the connection area and connection strength between the anti-misalignment bracket 11 and the plastic insulating body 1. When the electrical connector is subjected to external force, the protrusion 110 can better disperse the stress, so as to control the deformation of the plastic insulating body 1 to be smaller, and prevent the anti-misalignment bracket 11 from breaking or falling off from the plastic insulating body 1, thereby improving the structural stability of the entire electrical connector.

[0034] Furthermore, the structural through hole 111 is located at the bottom edge of the cavity of the plastic insulating body 1, with the protruding part 110 directly opposite the structural through hole 111. While ensuring the strength of the plastic insulating body 1, the structural through hole 111 can reduce the weight of the plastic insulating body 1, reduce material costs, and at the same time alleviate stress concentration to a certain extent, so as to better cope with the deformation of the plastic insulating body 1, and further improve the reliability of the product.

[0035] Example 3

[0036] Combination Figure 1 and Figure 3 As shown, in some optional embodiments, each group of structural positions includes an arc-shaped structural position 12, multiple structural partition positions 13 and multiple structural groove positions 14. The arc-shaped structural position 12 is arranged along the bottom axis of the plastic insulating body 1, the multiple structural partition positions 13 are symmetrically arranged on both sides of the arc-shaped structural position 12, and the multiple structural groove positions 14 are symmetrically arranged on both sides of the bottom of the plastic insulating body 1 based on the arc-shaped structural position 12.

[0037] In this embodiment, each group of structural positions may include multiple structural positions with different structures located at different positions. Taking the bottom central axis of the plastic insulating body 1 as a reference, an arc-shaped structural position 12 is set along the bottom central axis. The arc-shaped structural position 12 can be a semi-circular arc-shaped structural position with the arc protruding upward. Structural partition positions 13 can be symmetrically set on the left and right sides of the arc-shaped structural position 12. The structural partition positions 13 are recessed downward along the bottom edges of the arc-shaped structural position 12 to form recesses. The above-mentioned structural groove positions 14 are symmetrically set on both sides of the bottom of the cavity of the plastic insulating body 1. Ribs are provided between the structural groove positions 14 in each group of structural positions to separate them, forming an overall concave-convex structure.

[0038] In this embodiment, the positions and thicknesses of the arc-shaped structural position 12, the structural partition position 13, and the structural groove position 14 can be adaptively adjusted, enhancing the deformation resistance of the plastic insulating body 1 and minimizing its deformation. Combined with the synergistic effect of the protruding position 110, the arc-shaped structural position 12, the structural partition position 13, and the structural groove position 14, this systematic structural adjustment allows the plastic insulating body 1 to more evenly distribute stress when subjected to external forces or internal stresses, avoiding excessive deformation caused by localized stress concentration. This minimizes the overall deformation of the plastic insulating body 1, ideally controlling it to within 0.05mm, greatly satisfying the stringent reliability and stability requirements of high-precision electrical connectors and providing a solid guarantee for reliable connection and stable operation of the product.

[0039] Example 4

[0040] Combination Figure 1 and Figure 3 As shown, in some optional embodiments, an upwardly protruding limiting platform 15 is provided between the structural groove positions 14 on both sides of the bottom of the plastic insulating body 1. The limiting platform 15 is provided with a plurality of limiting holes 16, and a groove is provided between each limiting hole 16. The arc-shaped structural position 12 and the structural partition position 13 in each group of structural positions are provided in the groove.

[0041] In this embodiment, the limiting platform 15 protrudes upward from the bottom center of the plastic insulating body 1, and a limiting hole 16 for receiving the conductive terminal 2 is provided on the limiting platform 15, ensuring that the conductive terminal 2 and the limiting hole 16 can achieve a tight fit, forming a reliable mechanical connection and electrical connection.

[0042] Furthermore, grooves are formed between the limiting holes 16. When the electrical connector is subjected to external force or thermal stress, the grooves can change the propagation path and distribution state of the stress. When the stress passes through the grooves, it will be dispersed and attenuated due to the geometry of the grooves, thereby reducing the maximum stress value borne by the limiting stage 15 and the conductive terminal 2.

[0043] Furthermore, the arc-shaped structural position 12 and the structural partition position 13 are formed in the groove. The arc-shaped structural position 12, due to its curved shape, can undergo a certain degree of elastic deformation under stress, thereby absorbing and releasing some energy and reducing stress damage to the insulating body. The structural partition position 13, by increasing the structural rigidity of the insulating body, limits the deformation range of the groove, making the stress distribution more uniform. This multi-layered, multi-dimensional structural design effectively controls the overall deformation of the plastic insulating body 1, improving the adaptability and reliability of the electrical connector under complex working conditions.

[0044] Example 5

[0045] Combination Figure 3 As shown, in some alternative embodiments, the arc-shaped structural position 12 includes a semi-circular arc-shaped structural position that protrudes upward based on the structural groove.

[0046] In this embodiment, the arc-shaped structural position 12 is set as a semi-circular arc-shaped structural position and protrudes to the upper end of the structural groove. The semi-circular arc-shaped structural position can generate a certain elastic deformation when subjected to force, thereby absorbing and releasing some energy and reducing the damage of stress to the insulating body.

[0047] Example 6

[0048] Combination Figure 1 As shown, in some optional embodiments, structural slots 17 are respectively provided at the midpoints of both ends of the plastic insulating body 1. When the fixing piece 3 is inserted into the structural slot 17, the fixing piece 3 is limited and fixed based on the structural slot 17.

[0049] In this embodiment, the aforementioned structural slot 17 can be located on the middle of the outer wall of the cavity near both ends of the anti-foolproof mounting bracket 11 on the plastic insulating body 1. Based on the insertion of the structural slot 17 and the fixing piece 3, when it is necessary to install and fix the electrical connector, the installation and fixation between the electrical connector and the mounting wall can be achieved based on the fixing piece 3.

[0050] In some examples, the dimensions of the aforementioned structural slot 17 are adapted to the dimensions of the fixing piece 3, so that an interference fit can be achieved when the fixing piece 3 is inserted into the structural slot 17, so that the insertion is secure. The structural slot 17 includes two symmetrically arranged slot positions. The bottom and outer side walls of the slot positions are closed and limited, while the upper and inner side walls are open, so that the left and right sides of the fixing piece 3 can be securely inserted into the slot positions.

[0051] Example 7

[0052] Combination Figure 4 As shown, in some optional embodiments, the fixing piece 3 includes a limiting surface 31 and an extending surface 32, which are L-shaped.

[0053] In this embodiment, the limiting surface 31 of the fixing piece 3 is used to insert into the structural slot 17, and the extension surface 32 can be used to install and fix it to the external mounting wall. The limiting surface 31 and the extension surface 32 have an L-shaped structure, which allows the bottom of the electrical connector to fit against the mounting wall during installation, improving installation stability.

[0054] In some examples, mounting holes 33 may be provided on the extension surface 32. The mounting holes 33 may be non-open or open. Setting the mounting holes 33 to be open is more conducive to the application of fasteners of different sizes. For example, if the size of the fastener is slightly larger than the diameter of the mounting hole 33, setting the mounting holes 33 to be open can allow the mounting holes 33 to withstand greater stress, ensuring that the fastener can pass through the extension surface 32 and be installed and fixed to the mounting wall.

[0055] Example 8

[0056] Combination Figure 1 and Figure 4 As shown, in some alternative embodiments, first barbs 34 extend from both sides of the limiting surface 31, and the first barbs 34 are received and held in the structural slot 17.

[0057] In this embodiment, the left and right sides of the limiting surface 31 can be extended outwards, and first barbs 34 are formed at the extended edges. When the fixing piece 3 is inserted into the structural slot 17 from top to bottom, the extended first barbs 34 are respectively inserted into the slots of the structural slot 17, forming an interference fit. Furthermore, the barbed structure, with its sharp, thorn-like parts, embeds itself into the surface or interior of the slot during insertion. When subjected to external force, the barbs are firmly held in the slot, greatly increasing the friction and resistance at the connection point and effectively preventing accidental detachment of the inserted components. Moreover, even if there is a certain positional deviation during insertion, the barbed structure can automatically adjust and embed itself into the other component, achieving a reliable connection. This reduces the requirements for assembly precision, decreases the defect rate caused by assembly errors, and improves the overall quality of the product.

[0058] Example 9

[0059] Combination Figure 1 , Figure 2 and Figure 5 As shown, in some optional embodiments, the conductive terminal 2 includes a terminal body 21 and a terminal solder foot 22. The terminal body 21 and the terminal solder foot 22 have an L-shaped structure. The terminal body 21 is housed in a limiting hole 16, and a second barb 23 is provided at one end of the terminal body 21 near the terminal solder foot 22. The second barb 23 is engaged in the limiting hole 16.

[0060] In this embodiment, the terminal body 21 of the conductive terminal 2 serves as the main channel for current transmission and the critical path for signal transmission. It also provides mechanical support, facilitates installation and positioning, and ensures electrical performance and controls electromagnetic interference through special treatment. The terminal solder feet 22 can achieve a stable electrical connection and mechanical fixation to the circuit board through soldering. In high-power equipment, they assist in heat dissipation and maintain signal integrity in high-speed signal transmission scenarios.

[0061] The terminal body 21 and terminal solder feet 22 are L-shaped, with the terminal body 21 passing through and being housed in the limiting hole 16 for fixation. A second barb 23 is provided on the terminal body 21, located near the connection point between the terminal solder feet 22 and the terminal body 21. After installation, the second barb 23 engages in the limiting hole 16, forming a single integral part. The L-shaped structure of the terminal body 21 and terminal solder feet 22 of the conductive terminal 2, housed in the limiting hole 16 of the electrical connector's insulating body, provides stable support for the conductive terminal 2 in both vertical and horizontal directions, enhancing connection stability and resistance to external forces. Furthermore, the precise positioning within the limiting hole 16 facilitates installation. Additionally, the second barb 23 on the terminal body 21 engaging in the limiting hole 16 prevents the terminal from loosening and falling off, further ensuring the long-term stability of the electrical connection.

[0062] Example 10

[0063] In this embodiment, a wire harness is also provided, including wires and an electrical connector as described in the above embodiments connected to the wires.

[0064] In this embodiment, a wire harness is provided that can be used in various scenarios, including but not limited to automotive electronics, rail transportation, communication networks, and home appliances. The wire harness includes conductors and electrical connectors electrically connected to the conductors, as described in any of the above embodiments. Because the electrical connector has a foolproof mounting bracket 11 on the plastic insulating body 1, it can prevent equipment damage, circuit failure and safety hazards caused by mis-insertion, thereby improving the accuracy and safety of the insertion. The protruding part 110 and the structural through hole 111 can adjust the thickness of the protruding part 110 according to the deformation of the plastic insulating body 1, thereby effectively controlling the deformation of the foolproof mounting bracket 11. At the same time, multiple sets of evenly distributed structural positions are provided at the bottom of the plastic insulating body 1, and the structural positions, protruding parts 110 and structural through holes 111 are integrally formed on the plastic insulating body 1. Therefore, the deformation of the plastic insulating body 1 is limited by the thickness of the structural positions, protruding parts 110 and structural through holes 111. By adjusting the thickness of the structural positions, protruding parts 110 and structural through holes 111 as a whole according to the deformation of the plastic insulating body 1, the overall deformation of the plastic insulating body 1 can be controlled more effectively and less, thereby improving the reliability and stability of the electrical connector. Therefore, when the wire harness provided in this embodiment is applied to different scenarios, it can also realize the above-mentioned embodiment of the electrical connector and achieve the corresponding technical effects, which will not be described in detail here.
