Description

Technical Field

[0001] The present disclosure relates to the field of electronic connection accessories, and in particular to an electrical connector with a pre-pressing structure. Background Art

[0002] An electrical connector is a conductor device that bridges two conductors in a loop so that current or signals can flow from one conductor to another. An electrical connector is also a motor system that provides a separable interface for connecting two sub-electronic systems. In simple terms, it is a component used to complete electrical connections between circuits or electronic machines.

[0003] The representative connector among electrical connectors is FPC (Flexible Printed Circuit board) connector, which can be used for electrical connection of electronic devices such as LCD monitors, scanners, computer motherboards, telecommunication cards, memory, mobile hard disks, etc. In recent years, with the development of mobile devices, it has been widely used in audio, digital machines, cameras, mobile phones and other mobile devices, with good development prospects and huge market.

[0004] FFC (Flexible Flat Cable) is a signal transmission component that has the advantages of being able to bend arbitrarily and having high signal transmission, so it is widely used in many electronic products. The flexible flat cable is used in conjunction with an electrical connector, that is, as an FFC connector, which can transmit signals from one end to the other.

[0005] Usually, end users have high requirements for the spacing and height of such products. However, existing FPC connectors and other similar products are prone to deformation during assembly, packaging, and transportation, which affects the height and position of the terminals, and thus leads to poor contact during product use. Summary of the invention

[0006] In order to solve at least part of the above problems and defects, an object of the present disclosure is to provide a new type of electrical connector with a pre-pressing structure.

[0007] Based on this, according to one embodiment of the present disclosure, an electrical connector is provided, comprising: a main body, which includes a accommodating cavity; a terminal, which is arranged in the accommodating cavity, and the terminal includes a contact portion and a pre-pressing portion; a cover body, which is assembled on the main body, and the cover body includes a pre-pressing groove, and the pre-pressing portion can be abutted against the pre-pressing groove.

[0008] The electrical connector of this embodiment has a pre-stressing structure that can be installed in conjunction with the terminal. The pre-stressing structure provides a stable terminal gap, ensures the height and position of the terminal, avoids deformation of the product during assembly, packaging and transportation, reduces the probability of poor contact during product use, and can effectively improve the market competitiveness of the product.

[0009] In an example of the present embodiment, the cover body includes a first cover body and a second cover body, wherein the first cover body is rotatably connected to the body, and the second cover body includes the pre-pressing groove installed in cooperation with the pre-pressing portion.

[0010] In an example of this implementation manner, a plurality of pre-pressing grooves are arranged in an array on the upper surface of the second cover.

[0011] In one embodiment of the present embodiment, the second cover cooperates with the main body to form a plug-in slot for inserting a conductive connector to electrically connect with the terminal.

[0012] In an example of this implementation, the conductive connection member is a flexible printed circuit board or a flat cable.

[0013] In an example of this implementation manner, after the conductive connecting member is inserted, it pushes the contact portion to move so as to drive the pre-pressing portion to move away from the pre-pressing groove.

[0014] In an example of the present embodiment, the contact portion is a structure bent toward the bottom of the accommodating cavity, and the pre-pressing portion is a structure bent toward the bottom of the accommodating cavity.

[0015] In an example of the present embodiment, the elastic locking member is fixed in the accommodating cavity and has a snap-fit ​​portion for locking the conductive connecting member at a preset position after the conductive connecting member is inserted.

[0016] In an example of the present embodiment, the first cover can rotate relative to the main body after being operated, and push the elastic locking member to undergo elastic deformation to drive the locking portion to move, thereby unlocking the conductive connecting member.

[0017] In an example of this embodiment, the buckle portion includes an inclined surface to guide the insertion path of the conductive connector when it is inserted.

[0018] In an example of this embodiment, the terminal is electrically connected to the conductive connecting member via the contact portion.

[0019] In an example of the present embodiment, the terminal includes a first terminal and a second terminal, and the pre-pressing groove includes a first pre-pressing groove for pre-pressing the first terminal and a second pre-pressing groove for pre-pressing the second terminal.

[0031] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present disclosure and are not intended to limit the scope of the present disclosure. The expressions such as upper end, lower end, left side, right side, top, bottom, etc., used when describing the various components are not absolute, but relative. These expressions are appropriate when the various components are arranged as shown in the figure, but when the positions of the various components in the figure change, these expressions also change accordingly.

[0032] like Figure 1-Figure 10 As shown, an embodiment of the present disclosure provides an electrical connector 10 . Figure 1 1 is an exploded schematic diagram of an electrical connector 10, which includes a terminal 12, a body 14, and a cover 16. The terminal 12 includes a contact portion 121 and a pre-pressing portion 123. The body 14 includes a receiving cavity 141 for receiving the terminal 12. The cover 16 is assembled on the body 14, and the cover 16 includes a pre-pressing groove 161, and the pre-pressing portion 123 can be abutted against the pre-pressing groove 161.

[0033] In some examples, the cover 16 includes a first cover 16a and a second cover 16b. Figure 1 As shown, the first cover 16a is rotatably connected to the body 14. In some examples, a rotation connection portion 163 is provided on both sides of the first cover 16a, and correspondingly, a rotation connection hole 143 is provided on both sides of the body 14, and the first cover 16a and the body 14 are rotatably connected through the rotation connection portion 163 and the rotation connection hole 143. In some examples, the first cover 16a also includes a clamping portion 165, and correspondingly, the body 14 is provided with a matching clamping groove 145, and the first cover 16a is rotated and pressed down to close the body 14, and the first cover 16a and the body 14 are fixedly connected through the clamping portion 165 and the clamping groove 145. Optionally, the positions of the rotation connection portion 163 and the rotation connection hole 143, the clamping portion 165 and the clamping groove 145 are interchangeable.

[0034] In some examples, the contact portion 121 is a structure that is bent toward the bottom of the accommodating cavity 141, and the pre-pressing portion 123 is a structure that is bent away from the bottom of the accommodating cavity 141. The bending structure of the contact portion 121 minimizes the distance between its lower surface and the bottom of the accommodating cavity, so that the jig is first connected to it after insertion and causes elastic deformation to drive the pre-pressing portion to move. The bending structure of the pre-pressing portion 123 facilitates the overlap between the pre-pressing portion 123 and the pre-pressing groove 161 to ensure the pre-pressing effect. In some examples, the terminal 12 includes a first terminal 12a and a second terminal 12b, and the pre-pressing groove 161 includes a first pre-pressing groove for pre-pressing the first terminal 12a and a second pre-pressing groove for pre-pressing the second terminal 12b. In some examples, the first terminal 12a and the second terminal 12b are spaced apart from each other at equal intervals, and correspondingly, the first pre-pressing groove and the second pre-pressing groove are spaced apart from each other at equal intervals. Preferably, the first pre-pressing groove and the second pre-pressing groove have the same structure. In some examples, the first end of the first terminal 12a and the first end of the second terminal 12b are connected to the externally inserted conductive connector 20, and the second end of the first terminal 12a and the second end of the second terminal 12b are respectively disposed at two ends of the body 14, for realizing the electrical connection between the conductive connector 20 and other electrical components. In some examples, the first end of the first terminal 12a and the first end of the second terminal 12b are the contact portion 121 of the terminal 12, that is, the terminal 12 is electrically connected to the externally inserted conductive connector via the contact portion 121. In some examples, the conductive connector is a flexible printed circuit board or a flat cable. After the conductive connector is inserted, the contact portion 121 is pushed to move to drive the pre-pressing portion 123 to move away from the pre-pressing groove 161.

[0035] In some examples, the second cover body 16 b includes a pre-pressing groove 161 that is installed and arranged to cooperate with the pre-pressing portion 123 . Figure 2 Schematic diagram of the structure of the second cover 16b. Figure 3 for Figure 2 A magnified schematic diagram of area A in the figure. Figure 2 and Figure 3 As shown, the upper surface array of the second cover body 16b is provided with a plurality of pre-pressing grooves 161, which are evenly distributed at equal intervals and match the position, quantity, width, height, etc. of the terminals, thereby achieving pre-pressing of the terminals, providing a stable terminal gap, and ensuring the height and position of the terminals.

[0036] In some examples, the pre-pressing groove 161 includes an inclined surface 1611, a side wall 1613, and a plane 1615. The design of the inclined surface 1611 can reduce the probability of interference with the terminal during the installation of the second cover 16b, thereby improving the assembly quality and efficiency. The side wall 1613 isolates different terminals to avoid short circuits. The pre-pressing portion 123 is lifted up, and after the second cover is plugged in, the pre-pressing portion moves down and overlaps the plane 1615, which has a simple structure and is easy to implement.

[0037] In some examples, the second cover 16b includes a plug-in portion 167, the body 14 includes a plug-in position 147, and the second cover 16b and the body 14 are connected by horizontally inserting the plug-in portion 167 into the plug-in position 147. In some examples, the second cover 16b cooperates with the body 14 to form a plug-in slot 149 for inserting the conductive connector 20 to electrically connect with the terminal 12. Preferably, the plug-in space of the plug-in slot 149 is the same as the operating space for inserting a jig to operate the contact portion to drive the pre-pressing portion to move.

[0038] Furthermore, the present disclosure Figure 4-Figure 7 The working principle of the preloading structure is described in detail. Figure 4 As shown, by inserting the jig 30 into the lower surface of the terminal 12, the thickness of the jig 30 is greater than the preset minimum height of the operating space, the jig 30 acts on the contact portion 121 to cause it to elastically deform, and the contact portion 121 moves upward, thereby driving the pre-pressing portion 123 to move upward. Figure 5 for Figure 4 Schematic diagram of the structure of area B in FIG. Figure 5 It is shown that after the jig 30 is inserted, the pre-pressing portion 123 moves upward, and after the second cover 16b is plugged into the body 14, a certain space is reserved between the pre-pressing groove 161 and the pre-pressing portion 123 to avoid interference between the second cover 16b and the terminal during the plugging process.

[0039] like Figure 6 As shown, after the jig 30 is removed, the elastic deformation of the contact portion 121 disappears and returns to its original state, driving the pre-pressing portion 123 to move downward and overlap into the pre-pressing groove 161 of the second cover body 16b, so that the pre-pressing groove 161 realizes pre-pressing of the terminal. Figure 7 for Figure 6 Schematic diagram of the structure of area C in FIG. Figure 7 As shown, after the jig 30 is taken out, the pre-pressing portion 123 overlaps the pre-pressing groove 161 , and the pre-pressing portion 123 overlaps the plane 1615 of the pre-pressing groove 161 without any gap.

[0040] like Figure 8 The figure shows a schematic diagram of the connection between the electrical connector 10 and the conductive connector 20. Specifically, the electrical connector 10 includes an elastic locking member 18. After the conductive connector 20 is inserted into the insertion slot 149, the elastic locking member 18 locks it in a preset position. Figure 8The electrical connector 10 is electrically connected to the PCB board 40, so the conductive connector 20 is electrically connected to the PCB board 40 after being inserted into the electrical connector 10. When the first cover 16a is opened to rotate relative to the body 14, the first cover 16a acts on the elastic locking member 18, pushing the elastic locking member 18 to undergo elastic deformation and driving the snap-on portion 181 on the elastic locking member 18 to move, thereby unlocking the conductive connector 20. The snap-on portion 181 includes an inclined surface 1811, which guides the insertion path of the conductive connector 20 when it is inserted. In some examples, the body 14 is injection molded together with the terminal 12 and the elastic locking member 18.

[0041] Fig. 9 and Fig.10 Schematic diagram of the working principle of the elastic locking member in the electrical connector, wherein: Fig. 9 It is a schematic diagram of the structure of the elastic locking member locking the conductive connecting member. Fig.10 Schematic diagram of the structure of the elastic locking member unlocking the conductive connecting member. Fig. 9 After the conductive connector 20 is inserted into the plug-in slot, the snap portion 181 of the elastic locking member 18 is snapped into the corresponding snap position of the conductive connector 20, thereby locking the conductive connector 20. Even if it is disturbed by unexpected external force, the conductive connector will not be disconnected from the terminal 12 due to the stopping effect of the snap portion 181. Fig.10 The middle elastic locking member 18 is elastically deformed after being pushed by the first cover 16a, and the buckle portion 181 is separated from the buckle position of the conductive connector 20. At this time, the conductive connector 20 is disconnected from the terminal after being pulled outward.

[0042] Although the present disclosure is described herein with reference to specific examples, these specific examples are intended to be illustrative only and not limiting of the present disclosure. However, it is obvious to those skilled in the art that the disclosed embodiments may be changed, added or deleted without departing from the spirit and scope of protection of the present disclosure.
