Description

[Technical field]

[0001] The utility model relates to an electric connector, in particular to an electric connector which reduces unlocking difficulty and improves disassembly and assembly efficiency. [Background technology]

[0002] The Chinese patent application number CN00106407.X discloses an electrical connector 10a for installation on a panel 14. The panel 14 includes an opening 12, and the opening 12 has a pair of positioning grooves 16a and 16b. The electrical connector 10a includes a shell 20a, and the shell 20a includes a pair of opposite side walls 24. An integrally formed locking arm 40a is located on one of the side walls 24, and a locking protrusion 41 is located at the end of the locking arm 40a. When the electrical connector 10a is in the inserted position, the locking protrusion 41 is adjacent to the reverse side of the panel 14 and causes the locking arm 40a to bend or become "tilted". When the electrical connector 10a is in the final locking position, the locking protrusion 41 bites into one of the positioning grooves 16b under the action of the energy stored in the bent locking arm 40a, thereby fixing the electrical connector 10a in the final locking position, so that the electrical connector 10a and the panel 14 are installed more tightly.

[0003] The above structure has the following problems:

[0004] When the electrical connector 10a and the panel 14 need to be unlocked, the locking protrusion 41 needs to be separated and disengaged from the positioning groove 16b first. At this time, another jig is used to push back the locking protrusion 41 so that the locking protrusion 41 is separated from the positioning groove 16b, which increases the difficulty of unlocking the electrical connector 10a and the panel 14. At the same time, the jig may slip and collide with other parts of the connector 10a, causing damage to the connector 10a.

[0005] Therefore, it is necessary to design a new electrical connector to solve the above technical problems. [Utility Model Content]

[0039] The electrical connector 100 is used to be mounted on a fixing plate 3. The fixing plate 3 includes a protruding portion 31 and an opening 30. The electrical connector 100 includes a main body portion 1 and an operating portion 2 located below the main body portion 1.

[0040] The main body portion 1 houses a plurality of conductive terminals (not shown), and extends to form a plurality of movable arms 11, a plurality of limiting blocks 12 and a stop frame 10. In other embodiments, the number of the movable arms 11 and the limiting blocks 12 may also be one.

[0041] From both sides of the main body portion 1, there is one of the movable arms 11 respectively. Each of the movable arms 11 includes a clamping block 113, a clamping block 114, a first end 111 and a second end 112 opposite to the first end 111. The two first ends 111 are connected to the stop frame 10. The two second ends 112 and the stop frame 10 are separately arranged, and the operating portion 2 is integrally connected to the two second ends 112. The second end 112 further includes a first side surface 112a, a second side surface 112b and an end surface 112c connecting the first side surface 112a and the second side surface 112b. The first side surface 112a and the second side surface 112b are arranged opposite to each other in the front-back direction, and the first side surface 112a is farther from the main body portion 1 than the second side surface 112b.

[0042] The clamping block 113 is closer to the second end 112 than to the first end 111, and the clamping block 113 is located within the opening 30 and abuts against and is limited by the wall surface 301 of the opening 30 in the horizontal direction. When an external force is applied to the operating portion 2 to move it downward, the movable arm 11 is displaced downward along an arc with the first end 111 as the fulcrum, and the clamping block 113 is displaced downward in the first direction N to disengage from the wall surface 301 of the opening 30 for unlocking. The first direction N forms an angle with the horizontal direction, such that when the external force applied to the operating portion 2 is removed, the first end 111 can drive the movable arm 11 to rebound to its original position. In other embodiments, two or more of the same clamping blocks 113 may be provided on the movable arm 11, so that the movable arm 11 is more firmly latched with the fixed plate 3 in the horizontal direction; two or more of the movable arms 11 may be respectively provided on both sides of the main body portion 1. At the same time, each movable arm 11 extends outward to form a clamping block 114. The clamping block 114 is closer to the second end 112 than to the first end 111, and the clamping block 114 is located between the clamping block 113 and the second end 112. In other embodiments, the number of the clamping blocks 114 may be zero, two or more, and the clamping block 114 may also be closer to the first end 111 than to the second end 112.

[0043] The protruding portion 31 corresponds to the limiting block 12. The limiting block 12 is located above the protruding portion 31, and the clamping block 113 abuts against and is limited by the protruding portion 31 in the horizontal direction; at the same time, one of the limiting blocks 12 is located between the clamping block 113 and the second end 112. In other embodiments, two or more of the limiting blocks 12 may be provided between the clamping block 113 and the second end 112, so that the movable arm 11 is more firmly latched with the fixed plate 3 in the horizontal direction.

[0044] The stop frame 10 is located below the fixed plate 3 and is provided with an accommodation space S1 therethrough. The stop frame 10 extends downward to form an extended section 102, and a groove 104 is further provided corresponding to the clamping block 114. The movable arm 11 is located within the accommodation space S1, and the extended section 102 shields the outside of the movable arm 11. When the movable arm 11 is displaced downward, and after the clamping block 113 and the wall surface 301 of the opening 30 are unlocked, a part of the clamping block 113 is higher than the lower surface of the extended section 102.

[0045] Specifically, the first end 111 is connected to an inner wall 101 of the accommodation space S1 in the front-rear direction. The second end 112 is movably located within the accommodation space S1 and is separated from the blocking frame 10. Among them, the inner wall 101 of the accommodation space S1 shields the outside of the first side surface 112a, the second side surface 112b, and the end surface 112c. When the fastening block 113 is latched with the fixing plate 3, it avoids the collision and damage of the movable arm 11 and the second end 112 during use, thereby extending the service life of the movable arm 11. At the same time, it also avoids the displacement or even deformation of the movable arm 11 and the second end 112 under the influence of external force during use, resulting in the abnormal unlocking of the fastening block 113 and the fixing plate 3. And there is a first distance D1 between the first side surface 112a and the adjacent inner wall 101 of the accommodation space S1, and a second distance D2 between the second side surface 112b and the adjacent inner wall 101 of the accommodation space S1. Both the first distance D1 and the second distance D2 are greater than zero.

[0046] At the same time, the groove 104 penetrates the blocking frame 10 upward. When the operating part 2 moves downward under external force, the movable arm 11 deflects and displaces downward with the first end 111 as a fulcrum. The clamping block 114 moves downward and is received in the groove 104, thereby restricting the height of the downward displacement of the movable arm 11. When the clamping block 114 abuts against and is limited by the bottom surface of the groove 104, the movable arm 11 cannot continue to move downward, thus avoiding the situation where the movable arm 11 breaks and is damaged due to excessive downward movement.

[0047] The operation part 2 includes two operating rods 21, a connecting part 22 connecting the two operating rods 21, and an outer surface 23. The two operating rods 21 and the connecting part 22 enclose a hollow space S2, and a reinforcing rod 24 is further provided in the hollow space S2 to connect the two operating rods 21. In other embodiments, the number of the reinforcing rods 24 can be two or more. The two second ends 112 are respectively connected to the two operating rods 21, and the outer surface 23 is located on the operating rods 21 and is farther from the first end 111 relative to the second ends 112. In other embodiments, the operation part 2 can be provided with one operating rod 21 corresponding to the number of the movable arms 11. In addition, two operating rods 21 can also be connected to the same movable arm 11. There is a third distance D3 between the outer surface 23 and the inner wall 101 of the adjacent accommodation space S1 in the horizontal direction, and the third distance D3 is greater than zero. The end face 112c is indented inward relative to the outer surface 23 to form a notch C. The bottom surface C1 of the notch C is flush with the bottom surface 103 of the stop frame 10, or the bottom surface C1 of the notch C is lower than the bottom surface 103 of the stop frame 10, and in the up-and-down direction, the notch C is penetrated upward, so that the operation part 2 is easier to demold during the manufacturing process, and at the same time, when the bottom surface C1 of the notch C is higher than the bottom surface 103 of the stop frame 10, when the operation part 2 is displaced downward by an external force, it will collide with the inner wall 101 of the adjacent accommodation space S1 and be damaged is avoided.

[0048] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0049] 1. Compared with the previous unlocking method that requires a jig to push back the clamping block 113, by providing an operation part 2 below the main body part 1, and the operation part 2 is integrally connected to the second end 112;

[0050] Wherein, when the operation part 2 is moved downward by an external force, the movable arm 11 is elastically deformed downward, thereby driving the clamping block 113 to be displaced downward to disengage from the wall surface 301 of the opening 30, realizing the unlocking of the clamping block 113 and the fixing plate 3, so as to facilitate the subsequent horizontal sliding of the main body part 1 to unlock with the fixing plate 3, thereby reducing the unlocking difficulty of the electrical connector 100 and the fixing plate 3, improving the disassembly and assembly efficiency, and at the same time avoiding the situation that the jig slips when pushing back the clamping block 113 and collides with other parts of the electrical connector 100, resulting in damage to the electrical connector 100. In addition, the operation part 2 is located below the main body part 1, thereby avoiding affecting the assembly of the main body part 1 and the docking connector.

[0051] 2. By setting the extension section 102 to cover the outer side of the movable arm 11, when the operating part 2 moves downward due to external force, the movable arm 11 is displaced downward, and the retaining block 113 and the wall 301 of the opening 30 are unlocked, the retaining block 113 is partially or completely higher than the lower surface of the extension section 102, so that the extension section 102 plays a certain limiting role in the process of the retaining block 113 moving downward, thereby ensuring that the retaining block 113 is always located on the inner side of the extension section 102, and preventing the retaining block 113 from being damaged by external force during use.

[0052] 3. By arranging the stop frame 10 to be located below the fixing plate 3 and the limit block 12 to be located above the protruding portion 31, the fixing plate 3 is located between the limit block 12 and the stop frame 10, thereby limiting the displacement of the main body 1 in the up-and-down direction; the buckling block 113 and the protruding portion 31 are abutted and limited in the horizontal direction, thereby limiting the displacement of the main body 1 in the horizontal direction; at the same time, the buckling block 113 is close to the second end 112 relative to the first end 111, and one of the limit blocks 12 is located between the buckling block 113 and the second end 112, so as to avoid the protruding portion 31 extending too long to cause the part of the protruding portion 31 not covered by the limit block 12 to warp and deform, and at the same time, the protruding portion 31 is abutted and limited in the horizontal direction and the up-and-down direction with the buckling block 113 and the limit block 12 respectively, so that the protruding portion 31 and the electrical connector 100

[0053] The lock is more stable and not easy to shake and fall off.

[0054] 4. By setting a first distance D1 between the first side surface 112a and the inner wall 101 of the adjacent accommodating space S1, a second distance D2 between the second side surface 112b and the inner wall 101 of the adjacent accommodating space S1, the outer surface 23 and the inner wall 101 of the adjacent accommodating space S1 are

[0055] There is a third distance D3 between them along the horizontal direction, and the first distance D1 and the second distance D2

[0056] and the third distance D3 are both greater than zero, so that when the operating part 2 is pulled downward, the second end 112 and the operating part 2 are prevented from being scratched or collided with the inner wall 101 of the accommodating space S1 during movement and damaged, so that there will be no jamming when the operating part 2 is pulled downward, thereby further ensuring the smoothness of unlocking the holding block 113 and the fixing plate 3 and reducing the difficulty of unlocking.

[0057] 5. By setting the clamping block 114 closer to the second end 112 than to the first end 111, and the clamping block 114 being located between the clamping block 113 and the second end 112, the distance between the clamping block

[0058] 114 and the second end 112 is shortened, preventing the part of the movable arm 11 between the two from being easily broken or damaged when displaced downward when the distance between the clamping block 114 and the second end 112 is too long.

[0059] 6. By setting the operating part 2 to include two operating rods 21 and a connecting part 22 connecting the two operating rods 21, a hollow space S2 is formed by enclosing the two operating rods 21 and the connecting part 22. When pulling the operating part 2 downward, only need to insert a tool into the hollow space S2 and then pull downward to make the operating part 2 displaced downward, avoiding the situation of slipping when pulling the operating part 2, thereby reducing the pulling difficulty.

[0060] 7. By setting the reinforcing rod 24, it is prevented that when the operating rod 21 is externally squeezed, the movable arm 11 is driven to excessively deflect toward the main body part 1, resulting in the clamping block 114 disengaging from the groove 104; secondly, by setting the reinforcing rod 24 in the hollow space S2 to connect the two operating rods 21, the structural strength of the operating part 2 is enhanced, so that when the operating part 2 is externally squeezed or pulled, the operating rod 21 or the connecting part 22 is not easily deformed excessively and broken.

[0061] The above detailed description is only for the description of the preferred embodiments of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of this creation specification and drawings are included in the patent scope of this creation.
