Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a pin connector. Background Technology

[0002] Pin connectors are commonly used connection components in electronic devices, mainly used to achieve conductive connections and insulation protection in circuits. Traditional pin connectors typically consist of post-shaped pins made of conductive material and block-shaped insulators for insulation protection, in order to achieve electrical connections with external devices.

[0003] The shortcomings of existing technology:

[0004] 1. Insufficient ease of inserting the pin:

[0005] Traditional pin connectors have an external thread added to the pin insertion end on the post. They are disposable consumables. When inserting them into insulator sockets or external device interfaces, there may be problems such as greater resistance and difficulty in alignment, which affects assembly efficiency.

[0006] 2. Pins and insulators are not reusable.

[0007] 3. Low efficiency in wire installation:

[0008] If traditional connectors do not have slots and flared structures for quick wire installation, wire connection may require additional tools or complex operations, affecting assembly efficiency, and loose clamping may lead to increased contact resistance.

[0009] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0010] In view of the problems existing in the prior art, this utility model provides a pin connector.

[0011] To achieve the above objectives, the specific solution of this utility model is as follows:

[0012] This utility model provides a pin connector, comprising:

[0013] A pin is a cylindrical structure made of conductive material, with one end being the connection end and the other end being the insertion end;

[0014] An insulator, in the form of a block, is used to provide insulation protection for the pins. Several sockets are arranged in a matrix on the insulator, and the pins are inserted into the sockets in a one-to-one correspondence.

[0015] Furthermore, the insertion end of the pin is chamfered, which facilitates the insertion of the pin into the socket of the insulator and also facilitates docking with the interface of external devices.

[0016] Furthermore, the insertion end of the pin is hemispherical, which facilitates docking and insertion with the interface of external devices.

[0017] Furthermore, the outer wall of the insulator is provided with several longitudinal reinforcing ribs, which are used to enhance the structural strength of the insulator and prevent it from deforming and being damaged due to stress during use.

[0018] Furthermore, the pin and the insulator are connected by an interference fit to ensure the connection stability of the pin within the insulator.

[0019] Furthermore, the needle is rigidly connected to the insulator.

[0020] Furthermore, after the pin and the insulator are assembled by insertion, the pin and the insulator are fixedly connected by a locking structure;

[0021] The locking structure includes a protruding component disposed on the pin and a locking slot disposed on the insulator. The protruding component engages with the locking slot, and the engagement forms an anti-disengagement structure.

[0022] The protruding component includes a first segment, a second segment, a third segment, a fourth segment, and a fifth segment arranged in sequence. The front end of the first segment is chamfered. The diameter of the second segment is larger than that of the first segment. The diameter of the third segment is larger than that of the second segment. The diameter of the fourth segment is smaller than that of the third segment. The diameter of the fifth segment is larger than that of the third segment.

[0023] The first to fifth segments are all circular and form a stepped transition structure.

[0024] Furthermore, the surface of the pin is plated with a nickel layer or a 5μm gold layer.

[0025] Furthermore, one or both ends of the pin are provided with slots for inserting wires and pressing them in place, facilitating quick installation of the wires.

[0026] Furthermore, the end of the slot is provided with a flared structure with a flare angle of 30-45°.

[0027] The technical solution of this utility model has the following beneficial effects:

[0028] 1. Improve the ease of pin insertion and docking efficiency.

[0029] Chamfering and hemispherical end design

[0030] The chamfered structure at the insertion end of the pin facilitates quick alignment and insertion of the pin into the socket of the insulator, reducing insertion resistance and improving assembly efficiency;

[0031] The hemispherical design at the end reduces the positioning difficulty when docking with external equipment, avoids wear or jamming caused by rigid contact, and improves docking accuracy and reliability.

[0032] 2. Optimize electrical contact reliability and conductivity.

[0033] Flexible contact piece and surface coating

[0034] Elastic contact piece: The elastic contact piece on the inner wall of the socket elastically abuts against the outer surface of the pin, which can adaptively compensate for the tolerance fit between the pin and the socket, maintain stable contact pressure, reduce contact resistance fluctuations caused by vibration or temperature changes, and improve conductivity reliability.

[0035] Nickel / Gold Plating: The plating on the pin surface effectively prevents oxidation, corrosion and wear, ensuring stable conductivity during long-term use, while also improving surface smoothness and reducing contact resistance.

[0036] 3. Slot and flared structure:

[0037] Slot design: The slot at the end of the pin allows the wire to be directly inserted and secured by compression, without the need for additional tools or complicated wiring steps, significantly improving wire installation efficiency;

[0038] Flared structure: The 30-45° flare at the end of the slot facilitates quick alignment and insertion of the wire, reducing insertion resistance. At the same time, the tapered structure enhances the squeezing and fixing force on the wire, preventing loosening or detachment and ensuring the stability of the electrical connection.

[0057] Combination Figures 1-12 As shown, this utility model provides a pin 1 connector, comprising:

[0058] Pin 1 is a columnar structure made of conductive material, with one end being the connection end and the other end being the insertion end;

[0059] The insulator 2 has a block-shaped structure and is used to provide insulation protection for the pin 1. The insulator 2 has a number of sockets arranged in a matrix, and the pin 1 is inserted into the sockets one by one.

[0060] The insertion end of the pin 1 is provided with a chamfer 3, which facilitates the insertion of the pin 1 into the socket of the insulator 2 and also facilitates docking with the interface of external devices.

[0061] The insertion end of the pin 1 is hemispherical 4, which facilitates docking and insertion with the interface of external devices.

[0062] The outer wall of the insulator 2 is provided with a plurality of longitudinal reinforcing ribs 5, which are used to enhance the structural strength of the insulator 2 and prevent deformation and damage due to stress during use.

[0063] The pin 1 and the insulator 2 are connected by an interference fit to ensure the connection stability of the pin 1 within the insulator 2.

[0064] The inner wall of the socket is provided with an elastic contact piece that mates with the pin 1, and the elastic contact piece elastically abuts against the outer surface of the pin 1.

[0065] After the pin 1 and the insulator 2 are connected by insertion, the pin 1 and the insulator 2 are fixedly connected by a locking structure.

[0066] The locking structure includes a protruding component 6 disposed on the pin 1 and a locking slot disposed on the insulator 2. The protruding component 6 engages with the locking slot, and the engagement forms an anti-disengagement structure.

[0067] The protruding component 6 includes a first segment 7, a second segment 8, a third segment 9, a fourth segment 10, and a fifth segment 11 arranged in sequence. The front end of the first segment 7 is provided with a chamfer 3. The diameter of the second segment 8 is greater than that of the first segment 7. The diameter of the third segment 9 is greater than that of the second segment 8. The diameter of the fourth segment 10 is less than that of the third segment 9. The diameter of the fifth segment 11 is greater than that of the third segment 9.

[0068] The first segment 7 to the fifth segment 11 form a stepped transition structure.

[0069] The surface of the pin 1 is plated with a nickel layer or a 5μm gold layer.

[0070] One or both ends of the pin 1 are provided with slots 12 for inserting wires and pressing them in place, which facilitates quick installation of the wires.

[0071] The end of the slot 12 is provided with a flared structure 13, with a flaring angle of 30-45°.

[0072] The principle of this utility model is as follows:

[0073] I. Overall Structure and Core Functions

[0074] The pin 1 connector achieves conductive connection and insulating isolation of the circuit through the mating of conductive pins 1 and a socket matrix made of insulator 2. The connecting end of the pin 1 is used to connect to the wire or circuit board, and the insertion end is used to interface with external devices. The insulator 2 provides physical support and insulating protection for the pins 1, ensuring electrical isolation between each pin 1.

[0075] II. Principles of Mechanical Connection and Assembly

[0076] Pin 1 Insertion and Guiding Mechanism:

[0077] The chamfered corner 3 and hemispherical end 4 of the insertion end of pin 1 are geometrically optimized to reduce resistance when inserted into the socket of insulator 2 or external device interface. The chamfered corner 3 guides pin 1 to quickly align with the socket, and the hemispherical end 4 reduces friction and wear during rigid contact, allowing pin 1 to be smoothly inserted and positioned.

[0078] Insulator 2 structural reinforcement:

[0079] The longitudinal reinforcing ribs 5 on the outer wall of the insulator 2 increase the cross-sectional area and rigidity of the structure, disperse the stress generated during the insertion and extraction process or by external mechanical force, suppress the deformation of the insulator 2 (such as bending and compression), ensure the stability of the socket position, and avoid poor contact of the pin 1 due to structural deformation.

[0080] The fixing mechanism between pin 1 and insulator 2:

[0081] The pin 1 is rigidly connected to the insulator 2 to prevent the pin 1 from loosening axially.

[0082] Locking structure: When the stepped protrusion assembly 6 (first segment 7 to fifth segment 11) on the pin 1 is inserted into the locking slot of the insulator 2, the stepped structure with gradually changing diameter (the diameter of the second segment 8 and the third segment 9 increases, the diameter of the fourth segment 10 decreases sharply, and the fifth segment 11 has a square cross-section) achieves the functions of "locking-anti-disengagement-limiting".

[0083] During insertion, the chamfered section 3 of the first segment 7 guides the protruding component 6 into the slot, and the increased diameter sections of the second segment 8 and the third segment 9 open up the elastic wall of the slot.

[0084] The sudden reduction in diameter of the fourth section 10 causes the elastic wall of the slot to reset and engage in the stepped gap, forming an axial anti-disengagement mechanism;

[0085] The square cross section of the fifth segment 11 matches the inner wall of the slot, restricting the circumferential rotation of the pin 1 and ensuring that the position of the pin 1 is fixed inside the insulator 2.

[0086] III. Electrical Connection and Conductivity Principle

[0087] Resilient Contacts and Conductive Reliability:

[0088] Elastic contact piece: The elastic contact piece on the inner wall of the socket elastically abuts against the outer surface of the pin 1, generating contact pressure through elastic deformation to compensate for the machining tolerances of the pin 1 and the socket, ensuring stable electrical contact. Even under vibration or temperature changes, the elastic contact piece can still maintain a tight fit, reducing contact resistance fluctuations.

[0089] Surface plating: The nickel or gold layer on the surface of pin 1, through its highly conductive and corrosion-resistant material properties, prevents metal oxidation or corrosion, maintains long-term stable conductivity, and at the same time improves surface smoothness and reduces mechanical wear at the contact interface.

[0090] Wire connection mechanism:

[0091] Slot 12 and flared structure 13: The slot 12 at the connector end of pin 1 is used to insert the wire. The 30-45° flare at the end guides the wire to be quickly aligned and inserted, reducing insertion resistance. After insertion, the wire is fixed by squeezing the wall of the slot 12, forming a tight conductive connection using mechanical pressure, avoiding poor contact caused by loose wire. The flared angle design balances the ease of insertion with the squeezing and fixing force, ensuring a reliable electrical connection between the wire and pin 1.

[0092] IV. Functional Collaboration and Workflow

[0093] Assembly stage:

[0094] Pin 1 is quickly inserted into the socket of insulator 2 through the chamfered end 3 and the hemispherical end 4, and is initially fixed with glue;

[0095] The stepped structure of the protruding component 6 engages with the locking slot to complete axial anti-disengagement and circumferential limiting, forming a mechanical lock;

[0096] The wire is inserted into the slot 12 through the flared end, and then pressed to fix it, thus achieving a conductive connection with the pin 1.

[0097] Usage phase:

[0098] When inserting an external device, the chamfered corner 3 and hemispherical structure 4 of the insertion end of pin 1 help align the interface, and the elastic contact piece ensures stable electrical contact with the device interface;

[0099] The reinforcing rib 5 bears the insertion and extraction force and external stress, maintaining the structural stability of the insulator 2;

[0100] The locking structure and adhesive work together to prevent the pin 1 from loosening, and the plating protects the surface of the pin 1 to ensure long-term reliable conductivity.

[0101] Failure prevention:

[0102] If subjected to axial tensile force, the stepped engagement surface of the locking structure abuts against the inner wall of the slot, preventing the pin 1 from being pulled out;

[0103] If circumferential rotation occurs, the fifth segment 11 square structure will contact the limiting surface of the card slot to prevent the pin 1 from rotating and causing the contact position to shift.

[0104] V. Synergistic Effect of Core Innovation Points

[0105] Through multi-dimensional collaboration of mechanical structure optimization (chamfer 3, hemispherical 4, reinforcing rib 5, locking structure), electrical contact enhancement (elastic contact piece, plating), and installation convenience design (slot 12, flared opening), this utility model achieves the integrated function of "efficient assembly - stable connection - reliable conductivity - durable and damage resistant", solving the problems of traditional connectors in terms of insertion resistance, structural strength, and contact reliability.
