Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a ribbon cable connector. Background Technology

[0002] An electrical connector is a bridge that connects blocked or isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. It is an indispensable component for electrical connections in electronic devices. Electrical connectors used in the market vary widely in structure depending on the application or connection method. Connectors used on thin, flat objects such as FPC flexible circuit boards or FFC flexible flat cables are generally referred to as ribbon cable connectors.

[0003] The primary function of ribbon cables and connectors on the market is generally signal transmission, meaning most ribbon cable connectors do not have a ground wire function. However, to improve safety, some existing ribbon cables and connectors are designed with a corresponding ground wire structure. However, due to unreliable structural design, the ground wire structure in some existing ribbon cable connectors cannot be properly installed and restrained. This means that even when the ground wire structure is designed inside the connector and used with the ribbon cable, there is a possibility that the ground wire structure may accidentally come loose. Additionally, some ribbon cable connectors have unreliable internal structural design, causing the flip cover to not be properly restrained after installation. This means that it may be accidentally removed during the opening of the flip cover, and the flip cover on some connectors may have unreliable positioning, making it easy for it to tip over after being opened. Utility Model Content

[0004] The purpose of this utility model is to provide a ribbon cable connector that is structurally reliable, reliable in use, and ensures that the cover will not accidentally fall off during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a ribbon cable connector, including an insulating base, connecting terminals, a flip cover limiting terminal, and a flip cover that rotates on the insulating base. The insulating base includes a connector socket for inserting an external ribbon cable. The connecting terminals include a signal connection terminal and a ground terminal. The flip cover includes a lifting portion formed on one side of the flip cover and a flip cover rotating portion formed on the side of the flip cover opposite to the lifting portion. The flip cover limiting terminal is located on the insulating base and faces inward of the insulating base, forming a bent portion and an insertion portion. The insulating base has an inner insertion area for inserting the insertion portion. The bent portion is opposite to the inner insertion area and forms a rotating portion limiting area for inserting and rotating the flip cover rotating portion.

[0007] Preferably, there are several lifting cover limiting terminals, and each of them is inserted into the insulating rubber base through the insertion part. The insulating rubber base has several through areas for the lifting cover limiting terminals to be inserted between the lifting part and the lifting cover rotating part. The lifting cover limiting terminals that pass through the through areas are bent and avoided by the bending part and extend into the inner insertion area of ​​the insulating rubber base.

[0008] Preferably, the insulating base further includes a terminal insertion port that is arranged in the opposite direction to the opening direction of the connector mat. Through the terminal insertion port, a plurality of cover-opening limiting terminals and ground terminals are respectively arranged on the insulating base. There are two ground terminals, which are arranged symmetrically. The plurality of cover-opening limiting terminals are located between the two symmetrically arranged ground terminals.

[0009] The lifting cover rotation part includes a lifting cover limiting terminal corresponding part, a ground wire terminal corresponding part distributed on both ends of the lifting cover limiting terminal corresponding part, and a lifting cover flipping limiting part. The ground wire terminal corresponding part and the ground wire terminal are arranged opposite to each other. The ground wire terminal includes a ground wire signal transmission area formed on the side facing the ground wire terminal corresponding part for connecting with the ground wire signal area of ​​the external cable, and a lifting cover opening limiting area. When the lifting cover is lifted, the lifting cover opening limiting area and the lifting cover flipping limiting part abut against each other to form the lifting cover opening limit.

[0010] Preferably, the signal connection terminal includes a signal transmission part distributed within the connector pair socket, and a signal terminal connection part extending toward the connector pair socket and used to connect with an external circuit board to form a signal transmission.

[0011] The flip-top limiting terminal also includes a locking area and a fixed end facing away from the connector socket. The insulating base has a locking part that is adapted to the locking area. Through the cooperation of the locking area and the locking part, the flip-top limiting terminal is limited on the insulating base. The fixed end faces the external circuit board. During the connection stage between the ribbon cable connector and the external circuit board, the fixed end is used to limit the ribbon cable connector on the external circuit board.

[0012] Preferably, the terminal insertion port includes ground terminal limiting areas at both sides of the terminal insertion port. The ground terminal also includes a terminal insertion part formed in the ground terminal limiting area. The terminal insertion part includes an inner terminal limiting part that is inserted into the ground terminal limiting area and forms a tight fit, and an insertion port pressing part formed in the direction of the terminal insertion port. The ground terminal is limited in the ribbon cable connector by the tight fit of the inner terminal limiting part in the ground terminal limiting area and the contact of the insertion port pressing part in the terminal insertion port.

[0013] Preferably, the flip-over limiting part includes a stationary part that is opposite to the flip-over opening limiting area during the flip-over closing stage, and a flip-over abutting part that is abutting the flip-over opening limiting area during the flip-over opening stage, and a flip-over transition part is formed between the stationary part and the flip-over abutting part.

[0014] Preferably, the ground signal transmission area has a hook-shaped structure. The hook-shaped ground signal transmission area includes a hook portion formed towards the connector socket and an abutting portion formed towards the flip cover direction. When an external cable is inserted into the connector socket, it comes into contact with the ground signal area of ​​the cable through the hook portion. During the flip cover closing stage, the contact between the flip cover and the abutting portion causes the hook portion to slightly elastically displace towards the ground signal area of ​​the external cable, forming a pressing fit between the hook portion and the ground signal area of ​​the cable.

[0015] Preferably, the terminal insertion portion further includes a ground wire terminal electrical connection portion extending to the outside of the insulating base, through which the ground wire terminal electrical connection portion constitutes the grounding during the mating stage of the ribbon cable connector with the external circuit board.

[0016] Preferably, during the lid-closing stage, the stationary part and the lid-opening limit area are either in contact or have a gap.

[0017] The advantages of this invention are as follows: In addition to the components of the ribbon cable connector including an insulating base, a flip-up cover that can rotate on the insulating base, and a connection terminal for data signal transmission and grounding, it also includes a flip-up cover limiting terminal. The flip-up cover limiting terminal is inserted into the inner insertion area of ​​the insulating base via an insertion portion on the flip-up cover limiting terminal. A rotation portion is formed between the corresponding bend on the flip-up cover limiting terminal and the inner insertion area of ​​the insulating base to limit the insertion of the flip-up cover rotation portion. The positioning area, i.e., when the cover needs to be closed or lifted, can be achieved by the rotating part of the cover rotating in the limiting area, so as to limit the cover on the insulating base. Compared with the existing method that uses a groove on the terminal to hook one end of the cover for flipping and limiting, this method can greatly improve the reliability of the cover installation and limiting. It will also prevent the cover from accidentally coming loose from the insulating base due to excessive force or accidental pushing or pulling, which would cause the ribbon cable connector design to be unreliable.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0031] like Figure 1-10 As shown, the ribbon cable connector of this utility model embodiment includes an insulating base 2, connecting terminals, a cover limiting terminal 4, and a cover 1 that flips on the insulating base 2. The insulating base 2 includes a connector socket c for inserting an external ribbon cable a. The connecting terminals include a signal connecting terminal 3 and a ground terminal 5. The cover 1 includes a lifting portion 11 formed on one side of the cover 1 and a cover rotating portion 12 formed on the side of the cover 1 opposite to the lifting portion 11. The cover limiting terminal 4 is located on the insulating base 2 and faces inward of the insulating base 2, forming a bent portion 43 and an insertion portion 44. An inner insertion area 21 for inserting the insertion portion 44 is formed on the insulating base 2. The bent portion 43 is opposite to the inner insertion area 21 and forms a rotating portion limiting area e for inserting and rotating the cover rotating portion 12.

[0032] The above-described ribbon cable connector includes, in addition to, an insulating base 2, a flip-up cover 1 that can rotate on the insulating base 2, and a connection terminal for data signal transmission and grounding, a flip-up cover limiting terminal 4. The flip-up cover limiting terminal 4 is inserted into the inner insertion area 21 of the insulating base 2 via an insertion portion 44 on the flip-up cover limiting terminal 4. A rotating portion limiting the flip-up cover is formed between the corresponding bending portion 43 on the flip-up cover limiting terminal 4 and the inner insertion area 21 of the insulating base 2, thus limiting the insertion of the flip-up cover rotating portion 12. In zone e, when the cover 1 needs to be closed or lifted, the cover rotating part 12 can rotate in the limiting zone e to limit the cover 1 on the insulating base 2. Compared with existing methods that use grooves on terminals to hook one end of the cover 1 for flipping and limiting, this method greatly improves the reliability of the cover 1's installation and limiting. It also prevents the cover 1 from accidentally coming loose from the insulating base 2 due to excessive force or accidental pushing or pulling, which could lead to an unreliable design of the ribbon cable connector.

[0033] like Figure 2-4 As shown in Figures 6, 8, and 10, there are several lifting cover limiting terminals 4, all of which are inserted into the insulating base 2 through the insertion part 44. Several through-areas 13 are provided on the insulating base 2 between the lifting part 11 and the lifting cover rotating part 12 for inserting the lifting cover limiting terminals 4. The lifting cover limiting terminals 4 passing through the through-areas 13 are bent by the bending part 43 and extend into the inner insertion area 21 of the insulating base 2. Since the connection method of ribbon cable connectors on the circuit board b is generally soldering, by setting the number of lifting cover limiting terminals 4 to several, the lifting cover limiting terminals 4 can be connected to the circuit board b. When connecting, it is easier to connect. At the same time, by opening several through areas 13 on the insulating rubber base 2, when the cover limiting terminal 4 is fitted onto the insulating rubber base 2, the several cover limiting terminals 4 can first pass through several through areas 13 respectively, and then bend and avoid the cover 12 of the cover 1 by the bending part 43, and then insert into the inner insertion area 21 of the insulating rubber base 2 respectively. This also allows the cover 1 to be limited multiple times by the action of several cover limiting terminals 4, thereby greatly reducing the possibility of the cover limiting terminal 4 coming out of the insulating rubber base 2.

[0034] like Figure 1-10As shown, the insulating base 2 also includes a terminal insertion port d that is arranged in the opposite direction to the opening direction of the connector socket c. Through the terminal insertion port d, a plurality of cover-lifting limiting terminals 4 and ground terminals 5 are respectively arranged on the insulating base 2. There are two ground terminals 5, which are arranged symmetrically. The plurality of cover-lifting limiting terminals 4 are located between the two symmetrically arranged ground terminals 5. The cover-lifting rotating part 12 includes a cover-lifting limiting terminal corresponding part f and parts distributed on the cover-lifting limiting terminal corresponding part f. The ground terminal corresponding part 14 and the cover flipping limit part 15 are located at both ends of the ground terminal 14 and the ground terminal 5 are arranged opposite to each other. The ground terminal 5 includes a ground signal transmission area formed on the side facing the ground terminal corresponding part 14 for connecting with the ground signal area a1 of the external cable a, and a cover opening limit area 53. When the cover 1 is lifted, the opening limit of the cover 1 is formed by the contact between the cover opening limit area 53 and the cover flipping limit part 15.

[0035] The aforementioned ground signal transmission area has a hook-shaped structure. The hook-shaped ground signal transmission area includes a hook portion 52 formed towards the connector socket c and a contact portion 51 formed towards the cover 1. When an external cable a is inserted into the connector socket c, the hook portion 52 forms contact with the ground signal area a1 of the cable. During the cover 1 closing stage, the contact between the cover 1 and the contact portion 51 causes the hook portion 52 to slightly elastically displace the ground signal area a1 of the external cable a, thus forming a pressing fit between the hook portion 52 and the ground signal area a1 of the cable.

[0036] The flip-up limiting part 15 includes a stationary part 151 that is opposite to the flip-up opening limiting area 53 during the flip-up 1 closing stage, and a flip-up abutting part 153 that is in contact with the flip-up opening limiting area 53 during the flip-up 1 opening stage, and a flip-up transition part 152 is formed between the stationary part 151 and the flip-up abutting part 153; during the flip-up 1 closing stage, the stationary part 151 and the flip-up opening limiting area 53 are in contact or have a gap.

[0037] By configuring the cover rotation part 12 with the cover limiting terminal corresponding part f, the ground terminal corresponding part 14, and the cover flipping limiting part 15, and by configuring the ground signal transmission area and the cover opening limiting area 53 on the ground terminal 5, when the ribbon cable connector is in use, the cover 1 can be reliably limited by the cover limiting terminal corresponding part f, and the ground terminal corresponding part 14 and the ground signal transmission area can reliably connect the ground part on the ribbon cable connector with the ground signal area a1 on the ribbon cable. The ground signal transmission area is designed with a hook-shaped structure, which is more efficient than... Most existing solutions involve direct contact. However, the reliability of the connection between the ground wire portion on the ribbon cable connector and the ground signal area a1 on the ribbon cable is greatly improved, eliminating the possibility of loose connections. Furthermore, by incorporating a cover opening limit area 53, the cover flipping limit part 15 can rotate during the opening and closing state of the cover 1. This can be achieved by switching between the stationary part 151 and the flipping abutment part 153, allowing the flipping abutment part 153 to act on the cover opening limit area 53. Thus, when the cover 1 is lifted, the flipping abutment part 153 abuts against the cover opening limit area 53, thus limiting the opening of the cover 1.

[0038] like Figure 4-6 As shown in Figure 8, the signal connection terminal 3 includes a signal transmission part 32 distributed within the connector socket c, and a signal terminal connection part 31 extending towards the connector socket c and used to connect with the external circuit board b to form a signal transmission. The cover limiting terminal 4 also includes a locking area 45 and a fixed end 41 formed in the direction away from the connector socket c. The insulating base 2 has a locking part 22 that is adapted to the locking area 45. Through the cooperation of the locking area 45 and the locking part 22, the cover limiting terminal 4 is limited on the insulating base 2. The fixed end 41 faces the external circuit board b, and the ribbon cable is connected. During the connection stage between the device and the external circuit board b, the fixed end 41 forms a limiting design for the ribbon cable connector on the external circuit board b, which allows the signal connection terminal 3 and the flip cover limiting terminal 4 to be reliably distributed on the insulating base 2, ensuring that there is no interference between the signal connection terminal 3 and the flip cover limiting terminal 4. In addition to the cooperation between the insertion part 44 and the inner insertion area 21, the flip cover limiting terminal 4 inserted into the insulating base 2 also involves a locking part 22 and a locking area 45, which further ensures the limiting of the flip cover limiting terminal 4 on the insulating base 2.

[0039] like Figure 5-6As shown in Figure 9, the terminal insertion port d includes ground terminal limiting areas g at both sides of its edge. The ground terminal 5 also includes a terminal insertion part formed within the ground terminal limiting area g. The terminal insertion part includes an inner terminal limiting part 56 that is inserted into the ground terminal limiting area g and forms a tight fit, and an insertion port pressing part 54 formed in the direction of the terminal insertion port d. The ground wire is formed by the tight fit of the inner terminal limiting part 56 within the ground terminal limiting area g and the contact of the insertion port pressing part 54 within the terminal insertion port d. The terminal 5 is limited within the ribbon cable connector; the terminal insertion part also includes a ground terminal electrical connection part 55 extending to the outside of the insulating base 2. Through the ground terminal electrical connection part 55, a grounding design is formed for the ribbon cable connector to cooperate with the external circuit board b. This allows the ground terminal 5 inserted into the insulating base 2 to be limited not only by the insertion terminal limit part 56, but also by the action of the pressing part, so that the ground terminal 5 is further limited when inserted into the insulating base 2, thereby ensuring the reliability and practicality of the ground terminal 5 after it is installed on the ribbon cable connector.
