Description

Technical Field

[0001] The invention relates to a pin-type flexible connector, in particular to a pin-type flexible connector used for data communication. Background Art

[0002] Pin connectors are a type of connector commonly used in today's data communication applications. They have various connection methods, and have certain advantages in versatility and reliability. Among them, there are only a few common forms and other evolutions of the part that contacts the pin end conductor: leaf springs, claw springs, drum springs, etc.; none of them can change the basic contact method, the contact between the plane and the arc surface, and can only increase the contact point or tangent by changing the number of arc surfaces of the reed. In theory, they are connected and conducted in the form of point or tangent contact. In the operating environment of equipment using this type of connector, there are unstable factors of mechanical vibration, which causes the reed to follow the tremor or resonance in high and low frequency oscillations, affecting the communication quality.

[0003] Chinese patent CN217934281U discloses a Pogo-Pin connector, in which the bottom of the needle shaft is set as an inclined plane and is slidably connected in the needle tube, and an elastic member is abutted between the needle tube and the needle shaft; because the bottom of the needle shaft is an inclined plane, the elastic member will tilt and deform due to bias under the action of external force, so that the needle shaft also tilts and contacts the needle tube, and then the current is conducted through the needle shaft and the needle tube. However, since the needle shaft and the needle tube are clearance fit, when the two are connected, if the force is improper, the needle shaft and the needle tube may be disconnected instantly, causing the connector to conduct the current signal unstably, affecting its electrical performance. Summary of the invention

[0004] The present invention aims at the deficiencies of the prior art, and changes the pitch of the spiral spring to tighten or expand the inner diameter of the spiral so as to completely wrap the needle end conductor or detach the needle end conductor.

[0005] The present invention comprises: A flexible connector end, the flexible connector end comprising a flexible end insulating shell, a spiral spring type socket conductor is clamped inside the flexible end insulating shell, and the spiral spring type socket conductor is fixed in the flexible end insulating shell through a spring slider; A pin-end connector, the pin-end connector comprising a pin-type conductor and a pin-end insulating shell, the pin-type conductor being fixed inside the pin-end insulating shell, and the tip of the pin-type conductor being exposed outside the pin-end connector jack; The spiral jack of the spiral spring type jack conductor can be tightened or expanded in inner diameter by changing the pitch of the spiral, so as to achieve close winding, fitting or separation with the needle type conductor.

[0006] In some embodiments, the spiral spring type socket conductor further includes a spring deformation section and a spring displacement compensation section, which provide the required space for the displacement of the spiral socket by changing the angle and arc radius and can rebound and recover.

[0007] In some embodiments, a slider groove is provided in the flexible end insulating shell, the retaining spring slider is nested in the slider groove, and the slider spring slot of the retaining spring slider fixes the spiral spring type socket conductor inside the flexible end insulating shell.

[0008] In some embodiments, the spiral conductor fixed end of the spiral spring type socket conductor is clamped inside the flexible end insulating shell, the spiral socket is nested in the flexible end insulating shell socket, the reed deformation section and the reed displacement compensation section are clamped in the displacement compensation cavity of the flexible end insulating shell, and the spiral spring type conductor connection end falls into a fixed position between the flexible end wiring hole and the flexible end connection wire fixing hole.

[0009] In some embodiments, the length of the spiral jack and the spiral inner diameter are adjustable, and the position and shape of the reed deformation section and the reed displacement compensation section are variable to meet the connection sequence requirements.

[0010] In some embodiments, the connection terminal of the pin-type conductor can be made into a direct plug-in type, a patch type, or connected to a wire through a positioning hole or a connection hole according to actual needs.

[0011] In some embodiments, the flexible connector end is inserted into the interior of the pin end connector through the needle end connector socket guide, and the pin conductor enters the corresponding flexible end insulating shell socket, and as the flexible connector end is pushed forward, it penetrates into the spiral socket of the spiral spring socket conductor, and when the pushing stroke of the pin conductor reaches a predetermined distance, it contacts the retaining spring slider, and after continuing to push forward, the retaining spring slider pulls the spiral socket to deform, causing the inner diameter of the spiral socket to gradually shrink until it is tightly wrapped and fits with the tip of the pin conductor, forming a conductive state.

[0012] In some embodiments, the spiral jack can change the inner diameter size of the spiral to form a variable diameter spiral jack with a gradually smaller inner diameter, so as to achieve early contraction of the jacks at sequential or individual positions of the spiral jack to meet the needs of sequential conduction or early conduction on the line and delayed data connection.

[0013] In some embodiments, the position of the insulating shell slider in the slot is adjustable to meet the force requirements for sequential connection and close contact.

[0014] Beneficial effects of the present invention: 1. Improve communication quality Tight contact: By changing the pitch of the spiral jack, the inner diameter of the spiral can be tightened or expanded, thereby achieving a tight winding fit with the needle conductor. Compared with traditional flat and curved surface contact, this tight contact method can significantly reduce contact resistance and improve the stability and reliability of signal transmission.

[0015] Anti-vibration performance: In a mechanical vibration environment, the traditional reed contact method is prone to vibration or resonance, affecting the communication quality. However, the spiral spring jack conductor of this invention can maintain a stable contact state during vibration through the design of the reed deformation section and the displacement compensation section, effectively reducing signal interruption or distortion caused by vibration.

[0016] 2. Enhanced connection flexibility Adjustable spiral inner diameter: The inner diameter and length of the spiral jack can be adjusted as needed, which enables the connector to adapt to pin conductors of different sizes and improves the versatility and applicability of the connector.

[0017] Sequential conduction function: By changing the pitch and inner diameter of the spiral jack, the jack can be contracted sequentially or individual positions can be contracted in advance, thereby meeting the needs of sequential conduction or early conduction and delayed data connection. This function is particularly important in multi-signal transmission scenarios, which can optimize the order and timing control of signal transmission.

[0018] 3. Improve the durability of connectors Rebound recovery capability: The design of the spring deformation section and displacement compensation section not only provides sufficient deformation space, but also can automatically rebound and recover after the connector is used. This design prolongs the service life of the connector and reduces the deformation accumulation problem caused by long-term use.

[0019] Structural stability: The combination of the spring slider and the flexible end insulation shell provides a stable fixing structure for the spiral spring jack conductor, ensuring that the position and shape of the conductor can remain stable during multiple plugging and unplugging processes, further improving the durability of the connector.

[0020] 4. Simplify installation and maintenance Easy to install: The design of the connector allows the pin conductor to be connected to the screw jack through simple guided insertion, which is easy to operate and reduces installation time and cost.

[0021] Easy to maintain: Due to the reasonable structural design of the connector, the tight fit between the components and the certain adaptive ability, the problem can be quickly located and solved during the maintenance process, reducing the difficulty of maintenance.

[0022] 5. Adapt to various application scenarios Multiple wiring methods: The terminal of the pin conductor can be made into a straight-in type, a patch type, or connected to the wire through a positioning hole wiring hole according to actual needs. This diversity enables the connector to adapt to different equipment and application scenarios, improving its versatility and applicability.

[0023] Adjustable contact force: By adjusting the position of the slider in the insulating shell slot, the contact force requirements in different application scenarios can be met, further optimizing the performance of the connector. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present application provides a pin-type flexible connector for data communication, which includes a flexible connector end 1 and a pin-end connector 2, wherein a spiral spring-type socket conductor 11 is clamped inside a flexible end insulating shell 12 of the flexible connector end 1, and flexible end insulating shell locking surfaces 121 are provided on both sides of the flexible end insulating shell 12, and the spiral spring-type socket conductor 11 is fixed in the flexible end insulating shell 12 by a retaining spring slider 13, and the retaining spring slider 13 is nested in the flexible end insulating shell slider groove 125.

[0027] like Figure 2 and Figure 5As shown, specifically, the slider spring slot 131 of the spring slider 13 fixes the spiral spring type socket conductor 11 inside the flexible end insulating shell 12, the spiral conductor fixed end 111 of the spiral spring type socket conductor 11 is clamped inside the flexible end insulating shell 12, the spiral socket 112 of the spiral spring type socket conductor 11 is nested in the flexible end insulating shell socket 122, the spring deformation section 113 and the spring displacement compensation section 114 of the spiral spring type socket conductor 11 are clamped in the displacement profile compensation cavity 126 of the flexible end insulating shell 12, and the spiral spring conductor connection end 115 falls into the fixed position of the flexible end wiring hole 123 and the flexible end connection wire fixing hole 124.

[0028] Furthermore, the flexible connector end 1 changes the pitch of the spiral jack 112 to tighten or expand the inner diameter of the spiral, and the spring deformation section 113 and the spring displacement compensation section 114 change the angle and arc radius to achieve the space required for the displacement of the spiral spring jack conductor 11, and can rebound and recover.

[0029] Furthermore, the length of the spiral plug hole 112 and the size of the spiral inner diameter can be changed, and the position and shape of the reed deformation section 113 and the reed displacement compensation section 114 can be changed to achieve the sequential requirements of the connection.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown, the pin-end connector 2 includes a pin conductor 21, a pin-end insulating shell 22 and a pin-end connector locking surface 23. The pin conductor 21 is fixed inside the pin-end insulating shell 22, and the tip of the pin conductor 21 is exposed in the pin-end connector plug hole 221. The pin conductor terminal 211 can be made into a straight-insertion type according to actual needs (see Figure 5 ), SMD type (see Figure 4 ) or connect to the wire through the positioning hole wiring hole.

[0031] How this application works: The flexible connector end 1 is inserted into the pin end connector 2 through the pin end connector socket 221, and the pin conductor 21 enters the corresponding flexible end insulating shell socket 122, and as the flexible connector end 1 is pushed forward, it penetrates into the spiral socket 112 of the spiral spring socket conductor 11, and when the pushing stroke of the pin conductor 21 reaches a predetermined distance, it contacts the retaining spring slider 13, and continues to push forward. The retaining spring slider 13 pulls the spiral socket 112 of the spiral spring socket conductor 11 to deform, and the inner diameter of the spiral socket 112 gradually shrinks until it is tightly wrapped and fits with the tip of the pin conductor 21, forming a conductive state.

[0032] As one of the improvement methods, the spiral inner diameter size of the spiral jack 112 can be changed to form a variable-diameter spiral jack with a gradually smaller inner diameter, so that the jacks at individual positions of the spiral jack can be contracted in advance in sequence, or the online connection can be turned on in advance to delay data connection requirements, and the position in the insulating shell slider groove 125 can be changed to meet the force requirements of close contact for sequential connection.

[0033] Example 1: Communication device connection in a high vibration environment Background: In industrial automation production lines, communication equipment is often affected by mechanical vibrations. Traditional connectors are prone to poor contact in such environments, resulting in communication interruptions.
