Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a pin-type plug-in connector. Background Technology

[0002] In numerous fields such as electronic equipment, power systems, and industrial control, pin-type pluggable connectors, as key components for connecting and disconnecting circuits, are widely used in power connections and signal transmission for various devices. Their main function is to achieve electrical connections between two or more wires through the insertion and removal of plugs and sockets, thereby ensuring stable transmission of current or signals. With the rapid development of electronic technology, the performance requirements for connectors are increasingly stringent. They not only need excellent conductivity but also need to meet diverse application needs in terms of insulation safety, structural stability, ease of insertion and removal, and service life. For example, in everyday household appliances, automotive electronics, and industrial automation equipment, the quality of pin-type pluggable connectors directly affects the operational reliability and safety of the equipment; therefore, optimizing their design and performance has become an important direction for industry development.

[0003] Existing pin-type pluggable connectors have several shortcomings in practical applications. Regarding conductivity, some connectors use ordinary metal pins, resulting in poor conductivity and excessive current loss during transmission, potentially leading to overheating and affecting normal equipment operation. Furthermore, the pin surfaces lack effective protective treatment, making them susceptible to corrosion and rust in humid, dusty, or other complex environments, increasing contact resistance and potentially causing circuit interruption. In terms of insulation and safety protection, traditional connector base structures are poorly designed, making it difficult to effectively separate the positive and negative power lines, leading to wire entanglement and contact, increasing the risk of short circuits. Moreover, the base provides poor protection and fixation for the pins, resulting in insufficient insulation and posing a safety hazard of electric shock due to accidental contact with the pins.

[0004] In view of this, we propose a pin-type pluggable connector to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems of poor performance of conductive pins, which are prone to problems, unreasonable base design leading to many safety and structural hazards, and inconvenient insertion and removal in the above-mentioned prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pin-type pluggable connector includes a plug body, the plug body comprising:

[0008] The conductive pin has two terminals, which are electrically connected to the positive and negative power lines respectively.

[0009] The plastic base has a Y-shaped structure and is used to separate the positive and negative power lines. The plastic base wraps around the conductive pin to provide insulation and fixation.

[0010] An insulating outer shell, which is an insulating frosted transparent cover and is fixedly fitted onto the outer side of a plastic base.

[0011] Preferably, both conductive pins are made of brass and are galvanized or gold-plated to enhance conductivity, corrosion resistance, and wear resistance, extend service life, and ensure stable current transmission.

[0012] Preferably, both conductive pins protrude from the front side of the insulating shell and the front side of the plastic base, facilitating precise connection with the interface inside the socket and ensuring effective circuit continuity.

[0013] Preferably, the plastic base includes a main body and two branched seats connected to the main body. The tail ends of two conductive pins are respectively embedded and fixed on the two branched seats. An insulating frosted transparent cover is fixedly sleeved on the outer side of the two branched seats to further fix the pins and strengthen the insulation protection, while also organizing the circuit layout.

[0014] As a preferred option, the main body is equipped with reinforcing ribs to enhance the mechanical strength of the plastic base, prevent the pins from bending or shifting during insertion and removal, and ensure connection stability.

[0015] Preferably, the outer surfaces of the positive and negative power cords are provided with insulating sleeves. The insulating sleeves on the positive and negative power cords are located in the two bifurcated seats and pass through the main body seat, which enhances the insulation protection and fixing effect of the power cords, avoids short circuits due to contact, and facilitates maintenance.

[0016] Preferably, the two forked sockets and the insulating shell form a V-shaped insertion groove for the insertion and positioning of the plug on the socket, which provides guidance and positioning for the plug, ensures accurate pin alignment, enhances connection firmness, and reduces loosening and falling off.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] This pin-type plug-in connector connects and disconnects the circuit through the plug body. Two surface-treated brass conductive pins are electrically connected to the positive and negative power lines, respectively. The Y-shaped plastic base separates the two power lines and wraps around and fixes the conductive pins, providing insulation and fixation. An insulating shell is fitted over the plastic base for further protection. When the plug and socket are mated, the V-shaped insertion groove guides the socket plug to insert precisely, allowing the conductive pins to align with the corresponding interfaces inside the socket, thereby achieving stable current transmission.

[0019] In the prior art, some connectors use ordinary metal pins, which have poor conductivity and are prone to corrosion. However, the brass pins of this connector have excellent conductivity. The zinc or gold plating treatment on the surface can resist corrosion, reduce contact resistance, avoid problems such as large current loss, heat generation and circuit interruption, and ensure stable current transmission.

[0020] This pin-type pluggable connector features a Y-shaped plastic base that effectively separates the positive and negative power lines. Reinforcing ribs enhance mechanical strength, and an insulating sleeve strengthens the protection of the power lines, reducing the risk of short circuits and electric shocks. It also prevents pin bending and breakage, and the wiring layout is more organized, facilitating installation and maintenance. Furthermore, it offers more convenient and reliable mating. Existing technologies lack effective positioning and guiding structures, making mating difficult and prone to misalignment and loosening. The V-shaped insertion groove guides the plug precisely into place, enhancing connection strength and preventing pin damage, poor contact, and loosening. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following combination Figures 1 to 4 This application will be described in further detail.

[0028] This application discloses a pin-type plug connector, including a plug body. The plug body includes conductive pins 1 and an insulating shell 5. Both conductive pins 1 protrude from the front side of the insulating shell 5 and the front side of the plastic base 4.

[0029] The conductive pin 1 has two pins and is electrically connected to the positive power line 2 and the negative power line 3 respectively. Both conductive pins 1 are made of brass and are galvanized or gold-plated.

[0030] When it comes to the material and surface treatment of the conductive pin 1, brass is an extremely suitable choice. Brass itself has excellent conductivity, ensuring stable current transmission, reducing power loss, and guaranteeing the normal operation of electrical equipment. At the same time, brass also possesses good mechanical strength and ductility, able to withstand certain external forces during insertion and removal, making it less prone to breakage and extending the pin's service life. Furthermore, zinc plating or gold plating further enhances its performance. Zinc plating forms a dense protective film on the pin surface, effectively resisting the corrosion of moisture, oxygen, and other corrosive substances in the air, preventing rust, and maintaining good conductive contact. Gold plating offers higher chemical stability and conductivity, reducing contact resistance and minimizing heat generation due to poor contact. Its advantages are particularly pronounced in scenarios with high conductivity requirements, while also enhancing the pin's wear resistance and reducing wear during insertion and removal.

[0031] The plastic base 4 has a Y-shaped structure and is used to separate the positive power line 2 and the negative power line 3. The plastic base 4 wraps around the conductive pin 1 to provide insulation and fixation. The plastic base 4 includes a main body 41 and two branched seats 42 connected to the main body 41. The tail ends of the two conductive pins 1 are respectively embedded and fixed on the two branched seats 42. An insulating frosted transparent cover is fixedly sleeved on the outer side of the two branched seats 42. The main body 41 is provided with reinforcing ribs 43 to improve the mechanical strength during insertion and removal and prevent the pins from bending or shifting. The outer side of the positive power line 2 and the negative power line 3 are respectively provided with insulating sleeves 6. The insulating sleeves 6 on the positive power line 2 and the negative power line 3 are respectively located in the two branched seats 42 and pass through the main body 41.

[0032] The Y-shaped plastic base 4 naturally and effectively separates the positive power line 2 and the negative power line 3, preventing them from tangling or contacting each other, thus reducing the risk of short circuits and ensuring safe circuit operation. The plastic base 4's wrapping of the conductive pin 1 provides excellent insulation, preventing accidental contact with the pin by a person or other conductive object and thus avoiding electric shock. It also fixes the pin's position, ensuring it doesn't easily wobble or shift during insertion and removal. The reinforcing ribs 43 on the main body 41 significantly improve the overall mechanical strength of the structure, better withstanding external forces during insertion and removal, effectively preventing the pin from bending, deforming, or even breaking due to excessive force, extending the connector's lifespan, and ensuring connection stability. Furthermore, placing the insulating sleeves 6 of the positive and negative power lines 3 within the two branch seats 42 and passing through the main body 41 further strengthens the fixation and protection of the power lines, making the circuit layout more organized and facilitating installation, maintenance, and repair.

[0033] The insulating outer shell 5 is an insulating frosted transparent cover and is fixedly fitted onto the outer side of the plastic base 4. The two forked seats 42 and the insulating outer shell 5 form a V-shaped insertion groove 7 for inserting and positioning the plug on the socket.

[0034] The V-shaped insertion groove 7 formed between the two forked seats 42 and the insulating shell 5 plays a crucial role in positioning and guiding the connector and socket during mating. The V-shaped structure has natural guiding properties; when the plug is inserted into the socket, the V-shaped groove guides the plug accurately and smoothly into its predetermined position, reducing alignment difficulties during insertion and removal, making operation more convenient and effortless. Simultaneously, this positioning function ensures precise alignment between the conductive pin 1 and the corresponding interface inside the socket, preventing poor contact or pin damage due to misalignment, thus guaranteeing the stability and reliability of the circuit connection. Furthermore, after mating, the V-shaped groove also creates a certain clamping force on the plug, enhancing the robustness of the connection between the connector and socket, reducing loosening or detachment caused by external forces such as vibration and impact, and improving the overall safety of the connection.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
