Description

Technical Field

[0001] The utility model relates to a connector, more specifically, to a double-layer terminal and FPC automatic assembly connector. Background Art

[0002] Traditional connector designs can usually only accommodate one FPC line, which is not only costly, but also requires two connectors and two welding processes if there are two FPC lines, which reduces production efficiency. In addition, when installing the FPC line into the connector, it is often necessary to open the connector cover, insert the FPC line, and finally close the cover. This operation process is cumbersome, inefficient, and difficult to achieve automated assembly of equipment.

[0003] Chinese invention patent document CN101867107A discloses an FPC connector, comprising: a main body, a plurality of terminals and a flip cover, the main body having an insertion surface for FFC plugging, the plurality of terminals being fixed side by side on the main body, the first end of each terminal being provided with a contact, the first end of each terminal facing the insertion surface of the main body, and the characteristic: the flip cover can be flipped and arranged on the main body, and is located on the side of the main body opposite to the insertion surface. The middle part of the main body is provided with a plurality of equally spaced receiving grooves, the terminals are assembled in the receiving grooves, the second end of each terminal is a terminal tail, the terminal tail is provided with a half-open shaft cutout, a side of the flip cover is provided with a plurality of through holes, each of the through holes forms a rotating shaft corresponding to each of the through holes in the lateral direction, and the flip cover can be flipped up and down relative to the main body by means of the rotating shaft being placed in the half-open shaft cutout.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] The utility model provides a double-layer terminal and FPC automatic assembly connector.

At this time, the first front end reinforcement plate is in contact with the arc-shaped first plug-in arc piece. The rebound force of the first plug-in arc piece can effectively prevent the metal fatigue of the terminal and extend the service life. Since the first plug-in pin at the tail of the first plug-in terminal is in an "L" shape, and the second plug-in pin at the tail of the second plug-in terminal is in a straight shape, the second plug-in pin can play a role in pre-positioning after plugging, avoiding the movement and displacement of the connector caused by machine vibration or human accidental contact when welding other terminal pins and grounding plates, and preventing short circuit or poor conduction. By using the first locking ear and the second locking ear, the FPC line does not need a cover when it is installed, and can be directly installed with normal force. The first locking ear and the second locking ear will produce inward deformation during the installation process, and cooperate with the locking seat. After installation, the first locking ear and the second locking ear will rebound and be clamped by the locking seat to achieve a stable connection, reduce the mold opening and use of one cover, and facilitate automated assembly.

[0023] In addition, a guiding slope can be provided at the entrance of the first plug-in slot and the second plug-in slot. The guiding slope allows the FPC line to be slowly pushed into the connector without flipping the cover of the connector, and the design of the bevel end allows it to be locked when it comes out, which simplifies the operation steps, improves work efficiency, and makes it easier to realize automatic assembly of the equipment.

[0024] In addition, the bottom of the connection block may be provided with a first grounding plate and a second grounding plate, which simultaneously serve as grounding for the upper and lower FPC layers, thereby saving a grounding plate and further reducing the cost.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0040] As described in the background technology, in the prior art, for connectors, the traditional connector design can usually only accommodate one FPC line, which is not only costly, but also requires two connectors and two welding processes if there are two FPC lines, which reduces production efficiency. In addition, in the process of installing the FPC line into the connector, it is often necessary to open the cover of the connector, then put in the FPC line, and finally cover the cover. This operation process is cumbersome, the work efficiency is low, and it is difficult to achieve automatic assembly of the equipment.

[0041] In order to solve this technical problem, the utility model provides a double-layer terminal and FPC automatic assembly connector including a connection block 1, wherein a first plug-in terminal 5 and a second plug-in terminal 6 are arranged inside the connection block 1. The connection block 1 is provided with a first plug-in slot 11 and a second plug-in slot 12, wherein a first plug-in FPC 2 is arranged inside the first plug-in slot 11, and a first front end reinforcing plate 41 is arranged at the head of the first plug-in FPC 2, and a second front end reinforcing plate 42 is arranged at the head of the second plug-in FPC 3. The first front end reinforcing plate 41 cooperates with the first plug-in terminal 5, and the second front end reinforcing plate 42 cooperates with the second plug-in terminal 6.

[0042] Through the above structural design, the first locking ear 411 and the second locking ear 421 are used, so that the FPC line does not need a cover when it is installed, and can be directly installed with normal force. The first locking ear 411 and the second locking ear 421 will deform inward during the installation process, and cooperate with the clamping seat S. After installation, the first locking ear 411 and the second locking ear 421 will rebound and be clamped by the clamping seat, achieving a stable connection, reducing the mold opening and use of a cover, and also facilitating automated assembly.

[0044] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0046] like Figures 1 to 9 As shown, the double-layer terminal and FPC automatic assembly connector comprises a connection block 1 , and a first plug-in terminal 5 and a second plug-in terminal 6 are arranged inside the connection block 1 .

[0047] The connecting block 1 is provided with a first plug-in slot 11 and a second plug-in slot 12. The first plug-in slot 11 is provided with a first plug-in FPC2, and the head of the first plug-in FPC2 is provided with a first front end reinforcing plate 41. The second plug-in slot 12 is provided with a second plug-in FPC3, and the head of the second plug-in FPC3 is provided with a second front end reinforcing plate 42.

[0048] It should be noted that the first front end reinforcing plate 41 cooperates with the first plug-in terminal 5 , and the second front end reinforcing plate 42 cooperates with the second plug-in terminal 6 .

[0049] A pair of locking seats S are disposed on the side walls of the first plugging slot 11 and the second plugging slot 12. The locking seats S are triangular in shape.

[0050] The head of the first front reinforcing plate 41 is provided with a pair of first locking ears 411 , and the head of the second front reinforcing plate 42 is provided with a pair of second locking ears 421 . The first locking ears 411 and the second locking ears 421 match with the locking seat S.

[0051] It should be noted that the first locking ear 411 and the second locking ear 421 are both ear-shaped.

[0052] The first plug terminal 5 includes an L-shaped first plug body 51, a head of the first plug body 51 is provided with an arc-shaped first plug arc piece 52, the first plug arc piece 52 cooperates with the first front end reinforcement plate 41, and a tail of the first plug body 51 is provided with an L-shaped first plug pin 53.

At this time, the first front end reinforcement plate 41 is in contact with the arc-shaped first plug-in arc piece 52. The rebound force of the first plug-in arc piece 52 can effectively prevent terminal metal fatigue and extend the service life.

[0058] Since the first plug pin 53 at the tail of the first plug terminal 5 is in an "L" shape, and the second plug pin 63 at the tail of the second plug terminal 6 is in a straight line shape, the second plug pin 63 can play a role of pre-positioning after being plugged in, avoiding the connector from moving and deviating due to machine vibration or human accidental contact when welding other terminal pins and the grounding plate, thereby preventing short circuit or poor conduction.

[0059] By using the first locking ear 411 and the second locking ear 421, the FPC line does not need a cover when it is installed, and can be directly installed with normal force. The first locking ear 411 and the second locking ear 421 will deform inward during the installation process, and cooperate with the clamping seat S. After installation, the first locking ear 411 and the second locking ear 421 will rebound and be clamped by the clamping seat, achieving a stable connection, reducing the mold opening and use of a cover, and also facilitating automated assembly.

[0062] By using the guide bevel Q, the FPC line can be slowly pushed into the connector without flipping the cover of the connector, and the design of the bevel end can lock it when it comes out, which simplifies the operation steps, improves work efficiency, and makes automatic assembly of equipment easier to achieve.

[0063] The double-layer terminal and FPC automatic assembly connector provided in Example 1 or 2 is further optimized. Specifically, a first grounding plate 101 and a second grounding plate 102 are provided at the bottom of the connection block 1 .

[0064] The working mode of this embodiment is described below.

[0065] The first grounding plate 101 and the second grounding plate 102 simultaneously serve as grounding for the upper and lower FPC layers, thereby saving two grounding plates and further reducing the cost.
