DETAILED DESCRIPTION

[0034] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 11 As shown, an IDC connector with a transmission unlocking structure includes a plug-in female end assembly 1 and a male end assembly 2, a plurality of wires 6 are connected to the female end assembly 1, a plurality of female terminals 5 connected to the plurality of wires 6 are arranged in the female end assembly 1, and a plurality of PIN pins 7 connected to the plurality of female terminals 5 are arranged in the male end assembly 2; the female end assembly 1 includes a plug-in female end body 3 and a female end top cover 4, the female terminal 5 is arranged in the female end body 3, and the wires 6 are connected to the female end top cover 4. A guide plug 41 for controlling the plug-in state of the female end body 3 and the female end top cover 4 is formed on the female end body 3; a main body cantilever 33 is formed on both sides of the female end body 3, and a reserved cavity 35 for the inward deformation of the main body cantilever 33 is formed in the female end body 3; a buckle 34 is formed on the main body cantilever 33, and a slot 21 for engaging with the buckle 34 is formed on both sides of the male end assembly 2, and an auxiliary unlocking bracket 44 for controlling the deformation of the main body cantilever 33 is formed on both sides of the female end assembly 1.

[0036] The wire 6 on the female end assembly 1 corresponds one-to-one to the female terminal 5 in the female end assembly 1, and the female terminal 5 corresponds one-to-one to the PIN pin 7 in the male end assembly 2. The connection between the female terminal 5 and the PIN pin 7 is achieved by plugging the female end assembly 1 and the male end assembly 2, and the connection between the wire 6 and the female terminal 5 is controlled by the plugging position of the guide plug 41.

[0037] A guide plug 41 is formed in the middle part, a guide slot 31 matched with the guide plug 41 is formed in the female end body 3, and an initial locking groove 411 and a final locking groove 412 arranged along the plugging direction are formed on the guide plug 41, and an initial locking protrusion 311 matched with the initial locking groove 411 and a final locking protrusion 312 matched with the final locking groove 412 are formed in the guide slot 31.

[0038] The guide plug 41 and the female end top cover 4 are an integrated structure. When the female end top cover 4 is plugged into the female end body 3, the guide plug 41 contacts the female end body 3 first, and under the cooperation of the guide plug 41 and the guide slot 31, the plugging direction between the female end top cover 4 and the female end body 3 is guided and positioned, thereby ensuring the plugging stability between the female end top cover 4 and the female end body 3.

[0039] The initial locking groove 411 and the final locking groove 412 are arranged along the plug-in direction of the guide plug 41. When the guide plug 41 is plugged into the guide slot 31, the initial locking groove 411 first contacts the guide slot 31. As the guide plug 41 is plugged deeper, the initial locking groove 411 and the initial locking protrusion 311 are engaged, thereby realizing the engagement between the female end assembly 1 and the male end assembly 2. At this time, it is the initial locking state between the female end assembly 1 and the male end assembly 2. Since both the female end assembly 1 and the male end assembly 2 have a certain plastic deformation ability, as the guide plug 41 is plugged deeper, the initial locking groove 411 and the initial locking protrusion 311 are disengaged, and the final locking groove 412 and the final locking protrusion 312 are engaged, thereby realizing the engagement between the female end assembly 1 and the male end assembly 2. At this time, it is the final locking state between the female end assembly 1 and the male end assembly 2.

[0040] During actual use, the guide insert 41 in the female end top cover 4 is matched with the guide slot 31, and the installation stroke reaches the initial lock state, so that the initial lock groove 411 is snap-fitted with the initial lock protrusion 311, so that the female end top cover 4 avoids the risk of easy disengagement and overpressure in the initial state after being installed in the initial lock position, so that the female end top cover 4 and the female end body 3 (as well as the female terminal 5 installed inside) form an integral part.

[0041] The initial locking groove 411 and the final locking groove 412 are staggered on the guide plug 41, the initial locking protrusion 311 and the final locking protrusion 312 are staggered in the guide slot 31, the initial locking groove 411 and the final locking groove 412 are staggered along the plug-in direction of the guide plug 41, and similarly, the initial locking protrusion 311 and the final locking protrusion 312 are also staggered along the plug-in direction of the guide plug 41.

[0042] Ensure that during the insertion process of the guide plug 41, the initial locking groove 411 can only be engaged with the initial locking protrusion 311, and the final locking groove 412 can only be engaged with the final locking protrusion 312, and the initial locking groove 411 and the final locking groove 412 do not interfere with each other during the engagement process.

[0043] The female terminal 5 includes a piercing section 52 and a connecting section 53 connected to each other. A mounting groove 32 is formed in the female terminal body 3 and is limitedly abutted against the piercing section 52. The connecting section 53 is located in the mounting groove 32. A limiting groove 43 is formed on the female terminal body 3 and is used to limit and clamp the piercing section 52.

[0044] The width of the piercing section 52 is greater than the width of the connecting section 53, so that when the connecting section 53 is set in the installation groove 32, the connection between the piercing section 52 and the connecting section 53 is against the female end body 3, so that the female terminal 5 is positioned and installed on the female end body 3, and under the action of the female end body 3, the installation position of the female terminal 5 is supported. The piercing section 52 is set toward the electric wire 6, and the end of the piercing section 52 is formed with a sharp structure for piercing the surface of the electric wire 6, and the end of the connecting section 53 forms an electrical connection leg connected to the PIN needle 7.

[0045] A penetration hole 42 for passing the wire 6 is formed on the female end top cover 4. The penetration hole 42 and the limiting groove 43 are vertically intersected to ensure that the penetration hole 42 and the limiting groove 43 have an intersection point to achieve contact between the female terminal 5 and the wire 6.

[0046] During use, the wire 6 is inserted into the through hole 42 of the female end top cover 4, and then the female end top cover 4 is pressed through the insulation piercing device to drive the wire 6 to move. At this time, the wire 6 moves along the radial direction of the wire 6, and the female terminal 5 is always in a relatively static state during the movement of the wire 6. When the female end top cover 4 and the female end body 3 are in the initial locking state, the initial locking groove 411 is engaged with the initial locking protrusion 311, and the wire 6 moves to the end of the female terminal 5. At this time, the wire 6 and the female terminal 5 are not in contact or abutment.

[0047] Through the insulation piercing device, continue to press the female end top cover 4 to drive the wire 6 to form a displacement. At this time, the wire 6 moves along the radial direction of the wire 6. The female terminal 5 is always in a relatively static state during the movement of the wire 6. When the female end top cover 4 and the female end body 3 are in a final locking state, the final locking groove 412 is engaged with the final locking protrusion 312. The sharp structure of the female terminal 5 completes the piercing of the insulation skin of the wire 6, so that the female terminal 5 and the copper conductor in the wire 6 are precisely connected, thereby completing the connection between the female end assembly 1 and the wire 6.

[0048] The male end assembly 2 is assembled by installing the PIN pin 7 and the stabilizing plate 8 into the male end assembly 2 in sequence through automatic insertion equipment, and then the stabilizing plate 8 and the PCB board 9 are installed by mounting, and the male and female connectors are matched by inserting the female end assembly 1 and the male end assembly 2.

[0049] The main cantilever 33 and the female end body 3 are an integrated structure. The main cantilever 33 has better strength on the female end body 3. Both ends of the main cantilever 33 are connected to the female end body 3 to ensure the structural strength of the main cantilever 33. At the same time, when the main cantilever 33 is pressed, the support effect of the main cantilever 33 is ensured under the action of the connection at both ends of the main cantilever 33, ensuring the connection stability between the main cantilever 33 and the female end body 3.

[0050] The power unlocking bracket 44 is disposed in abutment with the surface of the main cantilever 33 . When the male and female connectors are mated, the power unlocking bracket 44 is disposed in abutment with the surface of the main cantilever 33 .

[0051] When the buckle 34 is engaged in the slot 21 , the main cantilever 33 abuts against the inner wall of the male end assembly 2 , thereby improving the plugging stability of the female end assembly 1 and the male end assembly 2 .

[0052] A plug-in cavity 22 is formed in the middle of the male end assembly 2 for easy plugging of the female end body 3. The card slot 21 is connected to the plug-in cavity 22. A stabilizing plate 8 for firmly installing the male end assembly 2 is provided in the male end assembly 2. The stabilizing plate 8 is connected to the PCB board 9 by means of mounting, thereby realizing the firm installation of the male end assembly 2 on the PCB board 9.

[0053] During actual use, the female end assembly 1 is inserted into the male end assembly 2. During the insertion process, under the action of the guide plug 41, the female end assembly 1 has a guiding and error-proofing design during the plugging process, ensuring that the female end assembly 1 and the male end assembly 2 are plugged in accurately and smoothly.

[0054] Buckles 34 are provided on both sides of the female end body 3 to complete the snap connection with the slots 21 of the male end assembly 2, so that the female end assembly 1 and the male end assembly 2 are ensured to be matched. The unlocking structure is arranged on the female end assembly 1, and the single main body cantilever 33 is not deformed enough under the force to complete the unlocking alone.

[0055] Instead, the main cantilever 33 is forced to further deform by pressing the power unlocking brackets 44 on both sides. The main cantilever 33 drives the movement of the buckle 34 during the deformation process through the overall unlocking mechanism until the buckle 34 is completely out of the slot 21. At this time, the female end assembly 1 and the male end assembly 2 can be separated by pulling the female end assembly 1, thereby completing the unlocking process.

[0056] At the same time, the power-assisted unlocking bracket 44 can also protect the main cantilever 33. Under the action of the power-assisted unlocking bracket 44, the main cantilever 33 will not be deformed due to a slight touch, resulting in the separation of the female end assembly 1 and the male end assembly 2. Under the pressing action of the power-assisted unlocking bracket 44, a clear unlocking touch can be given to the dismantling personnel to prevent the female end assembly 1 and the male end assembly 2 from being pulled forcefully, causing damage to the female end assembly 1 and the male end assembly 2, and affecting the use of the female end assembly 1 and the male end assembly 2.

[0057] A differentiated special-shaped female terminal 51 can be selected in the female terminal assembly 1. According to the requirements of product selection, conventional products can uniformly select conventional female terminals 5. However, if the functional requirements require an electrical connection check, the differentiated special-shaped female terminal 51 can be selected at the inspection position. At the same time, the internal structure of the special-shaped female terminal 51 in the female terminal body 3 will also be adapted and adjusted accordingly, which is achieved by replacing the mold insert of the plastic shell of the female terminal assembly 1. The connection of the special-shaped female terminal 51 will have a smaller engagement distance than the connection of the other pin positions. After ensuring the connection of the special-shaped female terminal 51, the effective contact of the other pin positions with a normal engagement distance is guaranteed.

[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0059] Although this article uses more of the following terms: female end assembly 1, male end assembly 2, slot 21, plug-in cavity 22, female end body 3, guide slot 31, mounting slot 32, body cantilever 33, buckle 34, reserved cavity 35, female end top cover 4, guide insert 41, through hole 42, limit slot 43, power unlocking bracket 44, female terminal 5, special-shaped female terminal 51, piercing section 52, connecting section 53, wire 6, PIN needle 7, stabilizing sheet 8, PCB board 9, etc., it does not exclude the possibility of using other terms.
