Description

Technical Field

[0001] This utility model relates to connectors, and more particularly to an electrical connector with a pull-tab unlocking mechanism. Background Technology

[0002] As crucial components for the transmission of electrical signals or power between electronic devices, the structural design and functionality of electrical connectors are essential to the performance and reliability of electronic equipment. Furthermore, electrical connectors widely employ position locking mechanisms to ensure connection stability and prevent accidental disconnection.

[0003] Furthermore, existing technologies already employ pull-tab unlocking mechanisms. These electrical connectors have a flexible pull tab on the outside of the connector body; pulling the tab triggers the unlocking mechanism, causing the connector to switch from a locked to an unlocked state. However, current pull-tab unlocking connectors frequently experience problems during use, such as uneven force application leading to improper direction or angle of force when pulling the tab, resulting in unlocking failure or damage to the pull tab. Therefore, improvements are needed.

[0004] In view of this, the applicant has devoted itself to studying the aforementioned prior art and applying theoretical principles to try to solve the above-mentioned problems, which has become the applicant's improvement target. Summary of the Invention

[0005] One objective of this invention is to provide an electrical connector with a pull-tab unlocking mechanism, which facilitates balanced force application and improves operational convenience.

[0006] To achieve the above objectives, this utility model provides an electrical connector with a pull-tap unlocking mechanism, comprising an insulating base, a conductive portion, a locking tab, and a pull strap. The insulating base includes a body and a tongue plate connecting to the body. The body has a top wall with a groove formed therein. The conductive portion includes multiple conductive pads disposed on the tongue plate and multiple wires connecting the conductive pads. The locking tab includes two spaced-apart U-shaped springs and a tab connecting the two U-shaped springs. The two U-shaped springs are positioned in the groove, and the tab spans between the U-shaped springs and has a through-slot. The pull strap includes two spaced-apart fixed sections and a gripping section connecting the two fixed sections. The two fixed sections are sleeved around the through-slot and engaged with the locking tab, thereby causing the gripping section to protrude from the insulating base.

[0007] In one embodiment of the present invention, the main body is formed with a plurality of locking blocks in the receiving groove, and the bottom surfaces of the two U-shaped spring pieces are respectively provided with a plurality of locking slots, in which locking blocks are engaged.

[0008] In one embodiment of the present invention, the main body has limiting blocks formed on both sides of the receiving groove, and the top walls of the two U-shaped spring pieces are pressed against the limiting blocks.

[0009] In one embodiment of the present invention, the electrical connector further includes a pressure shaft. The body has multiple claws and multiple stop blocks formed on one side of the receiving groove. The pressure shaft passes through the claws and is stopped by the stop blocks, thereby pressing against the two fixed sections.

[0010] In one embodiment of the present invention, the hook claw includes two outer hook claws located on the outer sides of two fixed segments and an intermediate hook claw located between the two fixed segments.

[0011] In one embodiment of the present invention, the mating connector has multiple locking slots, and the locking piece is provided with multiple locking parts on the top walls of the two U-shaped spring pieces respectively. The electrical connector is positioned with the mating connector by engaging the locking slots with the locking parts.

[0012] In one embodiment of the present invention, the pull strip includes an upper pull tab, a lower pull tab, and a concave folded tab connecting the upper pull tab and the lower pull tab. The pull strip forms a closed end at the position of the concave folded tab for wrapping around the through groove.

[0013] In one embodiment of the present invention, the length of the upper pull tab is greater than the length of the lower pull tab, and the upper pull tab is folded back at the end away from the concave fold tab and overlapped with the lower pull tab to form another closed end.

[0014] In one embodiment of the present invention, the upper pull tab has a break line at the end away from the concave tab.

[0015] In one embodiment of the present invention, the upper pull tab, the lower pull tab, and the concave fold tab have a connected slot in the middle position, thereby forming two fixed segments spaced apart.

[0016] Compared to existing technologies, the pull strap of this utility model's electrical connector includes two spaced-apart fixed sections and a gripping section connecting the two fixed sections. The two fixed sections are sleeved around the locking piece, and the gripping section protrudes from the insulating base. Furthermore, when the electrical connector of this utility model is inserted into a mating connector, it is positioned by the locking part of the locking piece engaging the locking groove of the mating connector. Additionally, when the electrical connector needs to detach from the mating connector, applying force to the gripping section of the pull strap moves the two fixed sections and the locking piece, thereby causing the locking part to disengage from the locking groove and achieve an unlocked state, allowing the electrical connector to be removed from the mating connector. Moreover, when force is applied to the pull strap of this utility model, it is evenly applied through the two fixed sections to balance the movement of both sides of the locking piece, avoiding problems such as unlocking failure or damage to the pull strap due to uneven force direction or angle, thus improving operational convenience and practicality.

[0038] The detailed description and technical content of this utility model are explained below with reference to the accompanying drawings. However, the drawings are provided for reference and illustration only and are not intended to limit the scope of this invention.

[0039] Please refer to Figure 1This is a schematic diagram illustrating the insertion of the pull-tap unlocking electrical connector 1 of this utility model into a mating connector 2. The electrical connector 1 includes an insulating base 10, a conductive portion 20, a locking tab 30, and a pull strap 40. The conductive portion 20 is disposed on the insulating base 10 and is used for electrical conduction to transmit or receive signals or power from the mating connector 2. The locking tab 30 is attached to the insulating base 10 and is used to thread the pull strap 40 through it.

[0040] It should be noted that the electrical connector 1 has multiple locking portions 31 on the locking piece 30. Furthermore, the mating connector 2 has multiple locking slots 3. When the electrical connector 1 is inserted into the mating connector 2, the electrical connector is positioned relative to the mating connector by engaging the locking portions 31 with the locking slots 3. A more detailed description of the electrical connector 1 with pull-tab unlocking is provided below.

[0041] Please refer to Figure 2 and Figure 3 The figures shown are an exploded perspective view and an assembled sectional view of the electrical connector with pull-tap unlocking according to this utility model. The electrical connector 1 of this utility model includes an insulating base 10, a conductive portion 20, a locking tab 30, and a pull strap 40. The insulating base 10 includes a body 11 and a tongue plate 12 connected to the body 11. The body 11 has a top wall 13, and a receiving groove 14 is formed in the top wall 13. The conductive portion 20 includes a plurality of conductive pads 21 disposed on the tongue plate 12 and a plurality of wires 22 connecting the conductive pads 21.

[0042] Furthermore, the locking piece 30 includes two spaced-apart U-shaped spring pieces 32 and an insert 33 connecting the two U-shaped spring pieces 32. The two U-shaped spring pieces 32 are positioned in the receiving groove 14. The insert 33 spans between the pair of U-shaped spring pieces 32 and is provided with a through groove 330. The pull strap 40 includes two spaced-apart fixing sections 41 and a gripping section 42 connecting the two fixing sections 41. Moreover, the two fixing sections 41 are fitted around the through groove 330 of the locking piece 30 and attached to the locking piece 30, thereby causing the gripping section to protrude from the insulating base 10.

[0043] Furthermore, the electrical connector 1 also includes a pressure shaft 50. The body 11 has a plurality of hooks 15 and a plurality of stop blocks 16 formed on one side of the receiving groove 14. The pressure shaft 50 passes through the hooks 15 and is stopped by the stop blocks 16, thereby pressing against the two fixed sections 41 of the pull strap 40. In one embodiment of this invention, the hooks 15 include two outer hooks 151 located outside the two fixed sections and an intermediate hook 152 located between the two fixed sections 41. Accordingly, the pressure shaft 50 can reliably and effectively press against the two spaced-apart fixed sections 41, thereby applying force more evenly to the pull strap 40 and balancedly driving the locking piece 30 to operate.

[0044] Furthermore, the main body 11 of this utility model has multiple locking blocks 17 formed in the receiving groove 14, and a limiting block 18 is formed on each side of the receiving groove 14. Also, the bottom surfaces of the two U-shaped spring pieces 32 are respectively provided with multiple slots 320. The locking piece 30 engages with the locking blocks 17 through the slots 320 of the two U-shaped spring pieces 32, and the top walls of the two U-shaped spring pieces 32 press against the limiting block 18 to be positioned in the receiving groove 14, thereby attaching to the insulating base 10.

[0045] Specifically, the pull strap 40 includes an upper pull tab 401, a lower pull tab 402, and a concave flap 403 connecting the upper pull tab 401 and the lower pull tab 402. The pull strap 40 forms a closed end at the position of the concave flap 403 for wrapping around the through slot 330. Furthermore, the length of the upper pull tab 401 is greater than the length of the lower pull tab 402, and the upper pull tab 401 is folded back and overlapped with the lower pull tab 402 at the end away from the concave flap 403, thereby forming another closed end.

[0046] In this embodiment, the upper pull tab 401, the lower pull tab 402, and the concave flap 403 have a connected slot 400 at the middle position, thereby forming the two spaced fixed segments 41. Furthermore, the upper pull tab 401 has a break line 404 at the end away from the concave flap 403. The break line 404 facilitates the concave-convex folding of the upper pull tab 401.

[0047] Please refer to Figure 4 This is a schematic diagram illustrating the separation of the electrical connector 1 with pull-tap unlocking and the mating connector according to this utility model. When the electrical connector 1 of this utility model is to be detached from the mating connector 2, applying force to the gripping section 42 of the pull strap 40 will cause the two fixing sections 41 and their inserted tabs 33 to move. At this time, the two U-shaped spring tabs 32 will move along with the insert tabs 33, thereby causing the locking parts 31 to disengage from the locking grooves 3. Accordingly, the electrical connector 1 and the mating connector 2 are unlocked by disengaging from their positioning, thereby allowing the electrical connector 1 to be removed from the mating connector 2.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to define the patent scope of the present utility model. Other equivalent changes that utilize the patent spirit of the present utility model should all fall within the patent scope of the present utility model.
