[0024] To make the purpose, technical scheme and advantage of the utility model more clear and obvious, below, combining with specific embodiment and referring to the drawings, the utility model is further explained in detail.It needs to be explained that the embodiment of the utility model and the feature in the embodiment can be combined mutually in the case of not conflicting.

[0025] It is understood that these descriptions are only exemplary, and not to limit the scope of the utility model.

[0026] Below, combining with the drawings Figures 1-4 Some embodiments of the utility model provide a TYPE-C female head connector.

[0027] The utility model discloses a TYPE-C female head connector, include: TYPE-C connecting female head 100, PCB connecting plate 200, plug sleeve body 300 and integrated in the signal protection chip 210 of PCB connecting plate 200 surface, in this embodiment, plug sleeve body 300 is sleeved in TYPE-C connecting female head 100 surface, and is fixed on the surface of PCB connecting plate 200 through TYPE-C connecting female head 100, the pin end of main plug core 110 is electrically connected with the input end of signal protection chip 210, one end of TYPE-C connecting female head 100 is equipped with electrode plate 111, is used for electrode arrangement, and both sides of electrode plate 111 are equipped with ear 120 and elastic sheet 130.Ear 120 is connected through rotation on the surface of electrode plate 111, and is in elastic abutment with the surface of elastic sheet 130, thereby forming stable mechanical buckling when the male head is inserted, improve the stability of connection, avoid the male head loose.Electrode plate 111 surface is equipped with accommodating groove 112, and damping strip 140 and elastic column 141 are movably installed in the inboard.

[0028] In this embodiment, the signal protection chip 210 includes a signal stabilization module, an interference suppression module, and a current control module. The signal stabilization module is used to monitor and adjust the signal transmission stability in the TYPE-C connector in real time to reduce signal jitter caused by external interference. The interference suppression module is used to automatically generate a suppression signal when electromagnetic interference is detected, thereby improving signal clarity. The current control module controls current fluctuations at the moment of plugging to protect the internal circuit of the connector.

[0029] Through the above design, when the TYPE-C male plug is inserted, the lugs 120 and the elastic sheets 130 are tightly buckled under the elastic action, and the elastic column 141 provides the elastic pushing force of the damping bars 140, so that the male plug remains in a stable state after plugging, thereby effectively preventing looseness and poor contact. In addition, the arrangement of the signal protection chip ensures the high-speed stability of signal transmission.

[0030] In another embodiment, the utility model further optimizes the structure of the electrode plate 111 and the damping bar 140 to adapt to more complex plugging environments. In this embodiment, the electrode plate 111 is provided with a convex step on the side of the lug 120, and the convex step and the surface of the lug 120 form a continuous inclined surface. When the TYPE-C male plug is inserted, the insertion force of the male plug will push the lug 120 to rotate inward, and at the same time, the lug 120 will be smoothly inserted under the guidance of the convex step, further enhancing the stability of the mechanical connection.

[0031] The elastic sheet 130 is a metal elastic strip structure, one end of which is fixedly connected to the side surface of the electrode plate 111, and the other end is a movable end. When the male plug is inserted, the movable end of the elastic sheet 130 exerts an ejection force on the male plug, thereby providing additional mechanical support after plugging to ensure the stability during the plugging process.

[0032] In addition, in this embodiment, the interference suppression module in the signal protection chip 210 is provided with a filter circuit and a phase modulator for further canceling low-frequency interference signals in the power supply and the environment. Through the phase modulation technology, the interference suppression module can automatically adjust the phase of the interference signal, thereby achieving more efficient signal interference cancellation. At the same time, the current control module limits the inrush current at the moment of plugging by increasing the current limiting circuit and the protection diode, and protects the internal circuit in the case of overload.

[0033] On the basis of the above two embodiments, the utility model can also be configured such that the number of damping bars 140 and elastic columns 141 is two, the damping bars 140 are movably installed on the inner side of the accommodating groove 112, and the elastic columns 141 penetrate through the electrode plate 111 and are connected perpendicularly to the surfaces of the two damping bars 140. When the male plug is inserted, the elastic action of the elastic column 141 makes the damping bars 140 tightly adhere to the inside of the male plug, realizing the damping effect and avoiding looseness.

[0034] In addition, the ear buckles 120, the elastic sheets 130, the damping strips 140 and the elastic columns 141 are all made of corrosion-resistant materials to ensure the service life of the connector in a high-humidity or corrosive environment. The design not only improves the durability of the equipment, but also ensures reliable connection in a complex environment.

[0035] Through the above-mentioned multiple embodiments and extended configurations, the utility model effectively solves the deficiencies of the traditional TYPE-C connector in connection stability and signal transmission reliability, and ensures higher performance and stability in the process of high-speed data transmission.

[0036] The working principle and use process of the utility model are as follows:

[0037] When the TYPE-C male head is inserted into the TYPE-C connection female head 100, the male head first contacts the ear buckles 120 and the elastic sheets 130 on the electrode plate 111. Under the action of the insertion force, the ear buckles 120 rotate inward and press the elastic sheets 130 to elastically deform, and the ear buckles 120 are lifted by the elastic action of the elastic sheets 130 to make the outer side of the ear buckles 120 tightly abut against the inner side of the male head to ensure the mechanical stability of the connection.

[0038] The damping strips 140 and the elastic columns 141 jointly act to realize the tight abutment of the damping strips 140 and the inner side of the male head through elastic thrust, thereby providing a damping effect after the male head is inserted, effectively preventing looseness and poor contact. This design can significantly improve the stability of the connection, and is especially suitable for scenarios with frequent plugging and unplugging.

[0039] Signal protection and interference suppression:

[0040] When the male head is inserted, the current control module in the signal protection chip 210 immediately starts to limit the inrush current through the current limiting circuit, preventing the current surge from damaging the connector and internal circuit. At the same time, the protection diode quickly responds when the current is abnormal, further protecting the safety of the equipment.

[0041] During signal transmission, the signal stability module monitors the transmission signal strength in real time and dynamically adjusts the gain through the automatic gain control circuit to ensure the stability of the signal in high-speed transmission.

[0042] If electromagnetic interference is detected, the interference suppression module generates a signal opposite to the interference through the filter circuit and the phase modulator to cancel the interference wave, thereby maintaining the clarity and stability of data transmission.

[0043] The signal protection chip 210 provides real-time protection during the TYPE-C connector plugging process and loose plugging connection to reduce signal jitter and electromagnetic interference. Through the following modules work together: signal stabilization module: during signal transmission, the signal stabilization module continuously monitors the signal strength and dynamically adjusts the gain through the automatic gain control circuit to maintain signal stability and prevent signal attenuation caused by interference or loose. When encountering strength changes, the module automatically adjusts to ensure that signal transmission quality is not affected. Interference suppression module: in the case of detecting electromagnetic interference, the interference suppression module starts the filter circuit and phase modulator, filters low-frequency interference signals and adjusts the phase of the interference signal, generates an opposite suppression signal to effectively cancel the interference and ensure the clarity of signal transmission. Current control module: during the TYPE-C connector plugging moment, the current control module controls the current size through the current limiting circuit to avoid the influence of current fluctuation caused by sudden current on the signal. In addition, the protection diode starts in the case of overload or abnormal current to further protect the internal circuit of the connector and avoid component damage. Through the coordinated work of these modules, the protection chip can effectively eliminate or reduce the problems caused by current fluctuation, signal jitter and electromagnetic interference during plugging and connection, thereby ensuring the stability of signal transmission and the safety of TYPE-C connector connection.
