Detailed Implementation
[0024] This utility model is as follows Figures 1 to 7 As shown, a connector with anti-interference function includes a housing 10, a first grounding terminal assembly 20, a second grounding terminal assembly 30, a third grounding terminal 40, and a fourth grounding terminal 50, wherein:
[0025] The first grounding terminal assembly 20 is distributed on one side of the housing 10, and the second grounding terminal assembly 30, the third grounding terminal 40, and the fourth grounding terminal 50 are distributed side by side on the other side of the housing 10. The first grounding terminal assembly 20 includes a first molded part 21, a first grounding piece 22, a first grounding terminal 23, conductive adhesive 24, and a shielding sheet 25. The first molded part 21, the first grounding piece 22, and the first grounding terminal 23 are molded together, and the conductive adhesive 24 and the shielding sheet 25 are molded together. The first grounding piece 22 has a first shorting point 222, which is tightly connected to the middle part of the first grounding terminal 23. The shielding sheet 25 has a second shorting point 252, which is tightly connected to the lower end of the first grounding terminal 23.
[0026] The first molded part 21, the first grounding piece 22, and the first grounding terminal 23 in the first grounding terminal assembly 20 are molded into a whole, and the conductive adhesive 24 and the shielding sheet 25 are molded and fixed. Then, the molded first molded part 21, the first grounding piece 22, and the first grounding terminal 23 are molded and fixed in the outer shell 10 with the molded conductive adhesive 24 and the shielding sheet 25. The first shorting point 222 of the first grounding piece 22 is connected to the middle of the first grounding terminal 23; the second shorting point 252 of the shielding sheet 25 is connected to the lower end of the first grounding terminal 23, so that the first grounding piece 22 and the first grounding terminal 23, as well as the shielding sheet 25 and the first grounding terminal 23, can be connected more stably, which can better improve the overall high-frequency performance and anti-interference performance.
[0027] The conductive adhesive 24 and the shielding sheet 25 are molded and fixed to enhance the shielding effect, effectively prevent electromagnetic interference, ensure the reliable operation of electrical equipment, and effectively prevent signal interference. The first shorting point 222 of the first grounding sheet 22 is connected to the middle of the first grounding terminal 23. The second shorting point 252 of the shielding sheet 25 is connected to the lower end of the first grounding terminal 23, thereby improving high-frequency signal performance, stabilizing characteristic impedance, reducing near-field and far-field interference, reducing signal attenuation, and improving the stability of high-frequency signals.
[0028] The shielding plate 25 is made of metal, and the first grounding plate 22 is made of metal spring. The shielding plate 25 can block external interference: the shielding plate 25 is usually made of conductive materials (such as copper, aluminum, stainless steel or plated metal), which can absorb or reflect external electromagnetic waves and prevent interference signals from affecting the sensitive circuits inside the connector; the shielding plate 25 can suppress internal radiation: when high-speed signal transmission occurs, electromagnetic radiation may be generated inside the connector. The shielding plate 25 can limit it to a local area to avoid interfering with other components or equipment.
[0029] The first grounding plate 22 is provided with bent protrusions 221 at intervals. The front end of the protrusion 221 forms the first shorting point 222. The middle part of the first grounding terminal 23 has a first shorting part 231. The first shorting point 222 and the first shorting part 231 are closely connected.
[0030] The bent protrusion 221 has a certain degree of elasticity. When it is tightly connected with the first shorting part 231, it can adapt to a certain degree of installation error and vibration, always maintain good contact pressure, reduce the risk of poor contact due to loosening, ensure the reliability of grounding, and enhance connection stability.
[0031] The sidewall of the shielding plate 25 has outwardly protruding grooves 251 at intervals. The front end face of the protruding grooves 251 forms the aforementioned second shorting point 252. The lower end of the first grounding terminal 23 has a second shorting portion 232. The second shorting point 252 and the second shorting portion 232 are tightly connected.
[0032] The raised groove 251 makes the connection between the shielding sheet 25 and the first grounding terminal 23 tighter, and can more effectively conduct the electromagnetic interference signal induced on the shielding sheet 25 to the grounding terminal, thereby enhancing the shielding capability against electromagnetic interference and protecting the internal circuit from the influence of the external electromagnetic environment.
[0033] The second grounding terminal assembly 30 includes a second molded part 31, a second grounding piece 32, and a second grounding terminal 33 that are molded and connected together. The second grounding piece 32 has a shorting surface 322 that is tightly connected to the second grounding terminal 33. The molded connection makes the second molded part 31, the second grounding piece 32, and the second grounding terminal 33 form an integral structure, reducing the possibility of relative displacement and loosening between components, and improving the mechanical stability of the assembly and the reliability of the electrical connection.
[0034] The first grounding terminal 23 is a 40-pin terminal, the second grounding terminal 33 is a 7-pin terminal, the third grounding terminal 40 is a 6-pin terminal, and the fourth grounding terminal 50 is a 15-pin terminal; the 40-pin terminal, 7-pin terminal, 6-pin terminal and 15-pin terminal are all arranged in a row at intervals.
[0035] Grounding terminals with different pin counts can adapt to the grounding requirements of different types and sizes of electrical equipment, providing wider applicability and being applicable to a variety of different electrical systems to meet diverse needs.
[0036] The first molded component 21 and the first grounding plate 22 are disposed in the middle of the housing 10, the conductive adhesive 24 and the shielding plate 25 are disposed on the lower side of the housing 10, and the first grounding terminal 23 is vertically disposed through the housing 10. The different components are reasonably distributed in different positions of the housing 10, making full use of the internal space of the housing 10, resulting in a more compact structure that is conducive to installation and use. The vertically disposed first grounding terminal 23 makes the current conduction path more direct and stable, reducing the possibility of signal interference and energy loss.
[0037] The housing 10 has a partition 11 arranged horizontally. The first grounding terminal assembly 20 is distributed on one side of the partition 11, and the second grounding terminal assembly 30, the third grounding terminal 40 and the fourth grounding terminal 50 are arranged side by side on the other side of the partition 11. The housing 10 has fixing feet 12 at both ends for fixing.
[0038] The partition 11 can reduce electromagnetic interference and electrical coupling between each other, and improve independence and stability; the fixing feet 12 at both ends of the housing 10 provide a stable mounting base, avoiding displacement or shaking due to vibration or external force, and ensuring safety and reliability during use.
[0039] The second grounding plate 32 is provided with a number of bent blocks 321 at intervals, and the front end face of the bent block 321 forms the aforementioned shorting surface 322; this improves the reliability and conductivity of the contact and makes the grounding effect more ideal.
[0040] The usage method and principle of this type of connector with anti-interference function are as follows:
[0041] The first molded component, the first grounding plate, and the first grounding terminal in the first grounding terminal assembly are molded into a whole, and the conductive adhesive and shielding sheet are molded and fixed. Then, the molded first molded component, the first grounding plate, and the first grounding terminal are molded and fixed in the outer shell with the molded conductive adhesive and shielding sheet. The first short-circuit point of the first grounding plate is connected to the middle of the first grounding terminal; the second short-circuit point of the shielding sheet is connected to the lower end of the first grounding terminal, so that the first grounding plate and the first grounding terminal, as well as the shielding sheet and the first grounding terminal, can be connected more stably, which can better improve the overall performance and anti-interference performance.
[0042] The key design feature of this invention is that the conductive adhesive and the shielding sheet are molded and fixed to enhance the shielding effect of the equipment, effectively prevent electromagnetic interference, ensure the reliable operation of electrical equipment, and effectively prevent signal interference. The first short-circuit point of the first grounding sheet is connected to the middle of the first grounding terminal; the second short-circuit point of the shielding sheet is connected to the lower end of the first grounding terminal, thereby achieving high-frequency signal performance, stabilizing characteristic impedance, reducing near-field and far-field interference, reducing signal attenuation, and improving the stability of high-frequency signals.
