Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, specifically to an electrical connector. Background Technology

[0002] Existing USB connectors typically have an integrally molded insulating base. During production, excess molten plastic, under injection pressure, has no corresponding dispersion path and can only be directly injected into the mold. The impact force from this direct, forward-flowing injection can cause defective products on the tongue and electrical terminals, affecting production quality. Summary of the Invention

[0003] The purpose of this application is to provide a technical solution to address the problems mentioned in the background section.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] An electrical connector includes a first rubber seat, a second rubber seat, and a tongue. The first rubber seat has an injection molding through hole a, and the second rubber seat has an injection molding through hole b. A flow channel protrusion a is provided at the first rubber seat of the injection molding through hole a, and a flow channel protrusion b is provided at the second rubber seat of the injection molding through hole b. The injection molding through hole a covers the first rubber seat and the second rubber seat within the tongue. At the same time, the flow channel protrusion a is tilted and offset to fit against both sides of the flow channel protrusion b to form an injection molding flow channel. The first rubber seat and the second rubber seat are also covered with a plurality of electrical terminals, and the contact portions of the plurality of electrical terminals are exposed from the surface of the tongue.

[0006] Preferably, it further includes a middle clip, one of which has a clearance opening, the clearance opening facing the injection molding flow channel, positioning the middle clip between the first glue seat and the second glue seat.

[0007] Preferably, the clearance opening has a rectangular structure.

[0008] Preferably, the clearance opening has a polygonal structure.

[0009] Preferably, both the flow channel protrusion a and the flow channel protrusion b have a cross-shaped structure.

[0010] Preferably, hook portions are formed on both sides of one section of the middle clip, and the hook portions extend from the side of the first adhesive base and the second adhesive base respectively and protrude along the end axis of the first adhesive base and the second adhesive base; T-shaped structures are formed on both sides of the other section of the middle clip away from the ends of the first adhesive base and the second adhesive base.

[0011] Preferably, the inclination angle of the flow channel protrusion a is 10°-55°.

[0012] Preferably, a reinforcing beam is also provided at the middle clamping piece at one end of the clearance opening.

[0013] Preferably, the reinforcing beam is composed of carbon fiber mixed with polyetheretherketone, and its general chemical formula is: Where CF represents the carbon fiber reinforcing phase, the The term represents a repeating structural unit of the polyetheretherketone (PEEK) matrix, where n is the number of repeating units. This refers to aromatic ether ketone type interfacial segments grafted onto the surface of carbon fibers via chemical bonding, where p is the number of repeating units in the interfacial segment, g is the grafting density parameter, and R is the linking group selected from –CO–, –O–, –NH–, – – (m is an integer from 1 to 6) or one or more of these.

[0014] Preferably, one side of the middle clip is also coated with a Perylene F insulating coating.

[0015] In summary, the technical effects and advantages of this invention are as follows:

[0016] In the injection molding process, the corresponding structure of this product is designed such that the injection through-hole a on the first housing and the injection through-hole b on the second housing are axially aligned in the mold and together form a through-hole injection position. The runner protrusion a at the corresponding through-hole is not directly opposite to the runner protrusion b, but is inclined at a predetermined angle and laterally offset from each other on both sides of the runner protrusion b. This forms an asymmetrical injection channel with a guide slope between the two runner protrusions. When excess molten plastic enters under injection pressure, it is forced to deflect and divert along the inclined and offset mating surface, thereby effectively weakening the impact force of direct injection and preventing the molten material from directly scouring the tongue and electrical terminals. Therefore, in the production process of this connector, the first and second housings can achieve precise control of the flow direction and filling state of the injection molten material through the inclined and offset mating of the runner protrusions a and b. This ensures the positional accuracy and yield rate of the connector during production and improves production quality. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 An electrical connector includes a first base 1, a second base 2, and a tongue 3. The first base 1 has an injection molding through hole a11, and the second base 2 has an injection molding through hole b21. A flow channel protrusion a12 is provided at the first base 1 of the injection molding through hole a11, and a flow channel protrusion b22 is provided at the second base 2 of the injection molding through hole b21. The injection molding through hole a11 covers the first base 1 and the second base 2 within the tongue 3. Simultaneously, the flow channel protrusion a12 is tilted and offset to fit against both sides of the flow channel protrusion b22, forming an injection molding flow channel 4. The ends of the first base 1 and the second base 2 are also respectively formed with a plurality of diversion holes 5 communicating with the injection molding flow channel 4. The first base 1 and the second base 2 are also respectively covered with a plurality of electrical terminals 6, and the contact portions of the plurality of electrical terminals 6 are exposed from the surface of the tongue 3.

[0029] Working Principle: When using this product, it is installed in the corresponding housing. The tongue 3, as the basic supporting component for the overall insertion and electrical connection, is confined within the predetermined space of the housing. During injection molding, the corresponding structure of this product is designed such that the injection through hole a11 on the first housing 1 and the injection through hole b21 on the second housing 2 are axially aligned in the mold and together form a through injection position. The runner protrusion a12 located at the corresponding through hole is not directly opposite to the runner protrusion b22, but is inclined at a predetermined angle and laterally offset from each other, fitting against the two sides of the runner protrusion b22. This forms an asymmetrical injection injection runner 4 with a guide slope between the two runner protrusions. When excess molten plastic enters under the injection pressure, it is forced to exit along the inclined and misaligned fitting surface, creating several diversion holes 5 that are offset from the flow and flow to the end of the housing. This effectively weakens the impact of direct injection and prevents the molten material from directly scouring the tongue 3 and electrical terminals 6. Simultaneously, the tilted, staggered bonding structure extends the molten material flow path and promotes full diffusion before the molten material enters the tongue 3 and the areas covered by the two adhesive seats. This allows the first adhesive seat 1 and the second adhesive seat 2 to more evenly cover the tongue 3 and form a tightly bonded overall structure after curing. During this process, several electrical terminals 6 are stably covered and fixed, and their contact parts are exposed from the surface of the tongue 3 under the mold constraint. Thus, the first adhesive seat 1 and the second adhesive seat 2 in this connector design, through the tilted, staggered bonding between the runner protrusions a12 and b22 during injection molding, can achieve precise control of the molten material flow direction and mold filling state, thereby ensuring the positional accuracy and electrical connection reliability of the terminals during production and improving production quality.

[0030] Preferably, the assembly also includes a middle clamp 7, one of which has a clearance opening 71. The clearance opening 71 faces the injection molding flow channel 4, positioning the middle clamp 7 between the first substrate 1 and the second substrate 2. In this embodiment, the middle clamp 7 is arranged between the first substrate 1 and the second substrate 2, serving as a structural intermediate layer between them. The clearance opening 71 is pre-formed at one location on the middle clamp 7, and in the assembled state, this clearance opening 71 directly faces the injection molding flow channel 4 defined by the misaligned fit of the flow channel protrusions a12 and b22. This allows the molten plastic to smoothly pass through the corresponding position of the middle clamp 7 along a predetermined injection path during injection without interfering with the middle clamp. The plate 7 forms a positive obstruction or scouring, thereby avoiding problems such as disordered molten material flow, sudden pressure changes, or uneven mold filling caused by the presence of the middle clamping plate 7. At the same time, the remaining areas of the middle clamping plate 7 without the opening 71 are covered by molten plastic during the injection molding process and stably clamped between the first plastic seat 1 and the second plastic seat 2. Structurally, this forms a three-in-one composite support system, so that after molding, the middle clamping plate 7 not only acts as a reinforcing part to improve the overall rigidity and deformation resistance of the tongue plate 3 and the plastic seat combination structure, but also ensures the continuity and controllability of the injection molding process through the correspondence between the opening 71 and the injection grooving channel 4. Ultimately, it achieves the dual functions of structural reinforcement and molding stability without interfering with the flow of the injection grooving plate.

[0031] Preferably, the clearance opening 71 is a rectangular structure, which allows the middle clamp 7 to meet the clearance requirements of the injection molding channel while having a clearer and more controllable geometric boundary. The rectangular clearance opening 71 is arranged along the extension direction of the injection molding channel 4, and its straight edge can form a stable limiting and guiding effect on the molten plastic during the injection molding process, so that the molten material maintains a relatively uniform flow cross section when passing through the middle clamp 7 without generating irregular shrinkage or turbulence. At the same time, the rectangular structure forms a clear force distribution path on the body of the middle clamp 7, which helps to avoid local stress concentration caused by arc or irregular opening. Thus, after the injection molding is completed, the middle clamp 7 can provide reliable structural support and rigidity enhancement between the first glue seat 1 and the second glue seat 2 through its main body area, and can also ensure a smooth and stable molding process and improve the consistency and reliability of the overall structure through the precise correspondence between the rectangular clearance opening 71 and the injection molding channel 4.

[0032] Preferably, the clearance opening 71 is a polygonal structure, which makes the clearance and guiding interface of the middle clamp 7 to the injection molding flow channel 4 more adaptable. The polygonal clearance opening 71 can match the asymmetric flow section formed by the injection molding flow channel 4 under the condition of misalignment by the combination of the number of sides, side length and the included angle of each side. In this way, it provides a passage window for the molten plastic at the location of the middle clamp 7 that is more in line with the actual flow pattern. This allows the molten material to obtain a smoother transition and distribution when passing through the clearance opening 71 and reduces the risk of uneven mold filling and weld lines caused by sudden changes in local flow rate. At the same time, the straight boundary of the polygonal opening can limit the boundary of the molten material and form a clearer covering contour after solidification. This is beneficial to improving the clamping and positioning stability of the middle clamp 7 by the first glue seat 1 and the second glue seat 2 and facilitates consistent control in mold processing and dimensional inspection. Ultimately, the middle clamp 7 can take into account structural reinforcement, flow channel matching and molding stability without interfering with the continuity of injection molding.

[0033] Preferably, both the flow channel protrusion a12 and the flow channel protrusion b22 have a cross-shaped structure, forming a three-dimensional flow-limiting configuration with multi-directional extension characteristics at the corresponding positions of the injection through-hole. The cross-shaped structure protrudes outward along at least two intersecting directions, thereby creating a multi-directional separation, diversion, and re-merging effect on the molten plastic during injection molding. When the flow channel protrusions a12 and b22 are positioned opposite each other in the injection direction and are in an inclined, staggered fit, the branches of their cross shape are not directly opposite each other, but rather mutually shield and stagger, allowing the molten plastic to... When the material passes through injection through holes a11 and b21, it is forced to bypass adjacent branches to form a multi-path flow state, which effectively weakens the straight impact and reduces the local flow velocity peak. At the same time, the multi-boundary constraint formed by the cross-shaped structure can improve the stability of the injection channel in different directions, so that the molten material can obtain a more balanced pressure distribution and flow direction control before entering the coverage area of ​​the first and second injection bases 1 and 2, thereby reducing the probability of short shots, air marks and poor welds. Finally, while ensuring the smoothness of injection, it significantly improves the overall molding quality and structural consistency of the injection base.

[0034] Preferably, hook portions 72 are formed on both sides of one section of the middle clamping piece 7. The hook portions 72 extend from the sides of the first rubber seat 1 and the second rubber seat 2 and protrude along the axial direction of the ends of the first rubber seat 1 and the second rubber seat 2, respectively. T-shaped structures 73 are formed on both sides of the other section of the middle clamping piece 7, away from the ends of the first rubber seat 1 and the second rubber seat 2. The hook portions 72 are integrally formed on both sides of one section of the middle clamping piece 7 and extend from corresponding positions on the sides of the first rubber seat 1 and the second rubber seat 2 during assembly, protruding outward along the axial direction of the ends of the two rubber seats. This allows the hook portions 72 to mechanically engage with the periphery of the ends of the rubber seats in an axial holding and lateral limiting manner. This provides a clear reference for the axial position of the middle clamping piece 7 relative to the first rubber seat 1 and the second rubber seat 2 before injection molding and suppresses its movement or swaying under the impact of mold closing and injection. Simultaneously, the outward-extending structure of the hook portions 72 can also... After injection molding, the middle clip 7, together with the encapsulating colloid, forms an inverted pull-out shaped structure, making it difficult for the middle clip 7 to be pulled out of the housing assembly under axial tensile loads or vibration loads, thereby improving the overall structure's anti-detachment reliability. When the middle clip 7, located away from the ends of the first housing 1 and the second housing 2, further forms a T-shaped structure 73 on both sides, the transverse flange of the T-shape effectively expands the stress-bearing and encapsulating interface area of ​​the middle clip 7 in this region. This allows the cured injection molding material to form a stronger locking and anti-rotation support at this location, and to distribute the external load more evenly within the housing of the first housing 1 and the second housing 2. This effectively improves the overall rigidity and fatigue resistance of the connector under insertion, torsion, and bending conditions. Ultimately, the middle clip 7 provides fast and reliable axial positioning and anti-pull-out constraint through the front hook portion 72, and the rear T-shaped structure 73 provides enhanced locking and anti-torsional support, achieving structural stability and molding consistency through the synergistic effect of both.

[0035] Preferably, the inclination angle of the runner protrusion a12 is 10°-55°; in different embodiments, the inclination angle of the runner protrusion a12 relative to the injection direction can be set in the range of 10° to 55°. When the inclination angle is set to 10°, the misalignment and shielding formed between the runner protrusion a12 and the runner protrusion b22 mainly changes the local pressure distribution of the molten plastic in the initial stage of injection, so that the axial high-speed flow maintains continuity while generating an asymmetric pressure gradient, thereby inducing micro-scale deflection of the melt front and weakening the direct momentum without significantly increasing the overall flow resistance, which can effectively reduce The initial stage of the injection process applies instantaneous impact loads to the surface of the tongue 3 and the root of the terminal, suppressing surface erosion and initial orientation unevenness caused by high-speed jets. When the tilt angle is set to the range of 20° to 30°, the projection occlusion ratio of the flow channel protrusion a12 in the injection direction is significantly increased, causing the injection channel to evolve from a near-axial through-type shape into a three-dimensional tortuous flow channel with lateral bypass components. At this time, the molten plastic is simultaneously subjected to shear rate redistribution and local backflow induction when passing through this area, causing the melt front to change from a single advancing interface to a multi-front parallel expansion shape, thereby entering the first glue seat 1 and the second glue seat. The self-homogenization process of the melt temperature and velocity fields is achieved before the area covered by the middle clip 7, which can reduce the filling time difference between different covered areas and significantly reduce the uncertainty of weld line position and strength dispersion. When the tilt angle is further set to 45°, a significant geometric blocking relationship is formed between the runner protrusion a12 and the runner protrusion b22 in the injection direction, which causes the molten plastic to produce obvious lateral diversion, re-merging and energy dissipation effects in the injection area. This transforms the high kinetic energy axial flow into a multi-directional diffusion filling flow, thereby effectively suppressing the impact of local high-speed jet on the tongue 3 and electrical terminal 6 areas. This reduces risks, improves the integrity of the coating in thin-walled areas and complex corners, and reduces gas retention and micropore defects. When the tilt angle is set to 55°, the effective axial component of the glue injection path is further compressed. The molten plastic has completed sufficient orientation reconstruction and pressure release before entering the coating space, allowing the glue to fill the gaps in the complex structure in a manner similar to volume diffusion. This significantly reduces the internal stress gradient after curing while sacrificing some flow efficiency, and improves the interfacial bonding continuity between the first glue seat 1, the second glue seat 2 and the middle clip 7, as well as the stability of the overall molded structure under long-term load and vibration conditions.

[0036] Preferably, a reinforcing beam 74 is also provided at one end of the clearance opening 71 at the middle clamp piece 7. Although the clearance opening 71 provides the necessary passage space for the injection molding flow channel 4, it also forms a weakened cross-section area at the corresponding position of the middle clamp piece 7. In this solution, the reinforcing beam 74 is precisely arranged at one end of the clearance opening 71 and protrudes along the main force direction of the middle clamp piece 7, structurally reinforcing this weakened area. This allows the middle clamp piece 7 to effectively resist the pressure fluctuations and scouring loads generated by the flow of molten plastic during injection molding without warping. The reinforcing beam 74, as part of the middle clip 7, is covered by the first adhesive seat 1 and the second adhesive seat 2 after injection molding and curing. This significantly improves the moment of inertia and bending stiffness of the middle clip 7 at this position, thereby enabling it to better withstand insertion and extraction forces, vibration loads, and stress concentration transmitted by the tongue 3 during connector use, and suppressing fatigue cracks or deformation propagation at the edge of the relief opening 71. Ultimately, the middle clip 7 achieves simultaneous improvement in structural strength and long-term reliability through the reinforcing beam 74 while ensuring smooth glue injection.

[0037] Preferably, the reinforcing beam 74 is composed of carbon fiber mixed with polyetheretherketone, and its specific chemical formula is: Where CF represents the carbon fiber reinforcing phase, the The term represents a repeating structural unit of the polyetheretherketone (PEEK) matrix, where n is the number of repeating units. This refers to aromatic ether ketone type interfacial segments grafted onto the surface of carbon fibers via chemical bonding, where p is the number of repeating units in the interfacial segment, g is the grafting density parameter, and R is the linking group selected from –CO–, –O–, –NH–, – – (m is an integer from 1 to 6) one or more of these are used to covalently connect the interface segments with oxygen-containing functional groups or surface active sites on the carbon fiber surface, forming a composite material structure in which the carbon fiber is linked to the polyether ether ketone matrix through interface grafted segments. This improves the local bending stiffness and shear bearing capacity of the centering clip 7 at the weakened area at the end of the relief opening 71 of the reinforcing beam 74 in this scheme, and suppresses the warping and displacement generated at this location under injection pressure pulsation and subsequent insertion and extraction loads. At the same time, since the interface grafted segments and the polyether ether ketone matrix have the same aromatic ether ketone structure, a more continuous interface transition zone is formed after curing, and the tendency of interface debonding between the carbon fiber and the matrix is ​​reduced. This improves the stress transfer efficiency between the fiber and the matrix and reduces the probability of crack generation under cyclic loads. In turn, it improves the stability of the coating and bonding of the centering clip 7 of the first adhesive seat 1 and the second adhesive seat 2, as well as the structural reliability and durability of the connector under vibration, thermal cycling and long-term load conditions.

[0038] Preferably, at least one side of the middle clip 7 is further coated with an insulating coating. The insulating coating covers the surface of the middle clip 7 near the electrical terminal 6, so that the middle clip 7 forms effective electrical isolation when it approaches or contacts the adjacent electrical terminal 6. This avoids the risk of accidental conduction or leakage between terminals due to assembly tolerances, insertion vibration or long-term use, while improving the electrical safety and reliability of the overall electrical connector without significantly increasing the structural size. Specifically, the insulating coating is a Pyrelin F insulating coating 8. The Pyrelin F is deposited on the surface of the middle clip 7 via vapor deposition to form a dense and continuous covering layer, enabling uniform coverage without increasing the structural size of the middle clip 7. Compared to conventional coated insulating materials, Pyrelin F has high dielectric strength, low pinhole rate, and precisely controllable film thickness. It can provide stable and reliable electrical isolation under structural conditions where the spacing between the middle clip 7 and the upper and lower rows of electrical terminals 6 is limited. Simultaneously, Pyrelin F material has excellent chemical resistance and damp heat resistance, maintaining coating integrity during subsequent secondary molding and long-term insertion / removal use, avoiding insulation performance degradation due to coating cracking, peeling, or moisture absorption. This significantly improves overall electrical safety and long-term reliability in electrical connector structures with high-density terminal arrangements. Furthermore, in this embodiment, the polymeric repeating unit of Pyrelin F can be defined by the general chemical formula (I) as [p- C6H(4-x)Fx—CH2—CH2]n, where n is the degree of polymerization and is an integer greater than 1, and x represents the number of fluorine substitutions on the benzene ring, preferably x=4 to form tetrafluoro-substituted phenelzine F on the ring, which also often corresponds to the VT-4 system. This forms a dense and continuous insulating interface without significantly increasing the thickness of the middle clip 7 and reduces the risk of pinholes and edge thinning, thereby suppressing accidental conduction or leakage between terminals in assembly tolerance, insertion vibration and long-term service. Another commonly used high heat-resistant fluorinated phenelzine system can also be defined by the general chemical formula (II) as [p-C6H4—CF2—CF2]n, that is, the fluorinated repeating unit on the bridge chain. Its fluorinated structure can significantly improve the resistance to oxidation, damp heat and chemical environment retention, so that the insulating coating can still maintain the integrity of the coating and maintain the consistency of insulation performance under the secondary molding and repeated insertion and extraction loads of this scheme, thereby improving the overall electrical safety, connection stability and long-term reliability of the electrical connector.
