Abstract

The present invention provides an electrical connector for use with a circuit board. The electrical connector includes a latching actuator and a latching auxiliary component. The latching actuator includes a latching structure that can be moved to a latching position to latch the circuit board, thereby preventing the circuit board from being disengaged from the plugged electrical connector when subjected to external force. Furthermore, the latching actuator can be subjected to force to move the latching structure to a non-latching position to release the latching of the circuit board. When the latching structure moves to the non-latching position, the latching actuator forces the latching auxiliary component to elastically deform. At this point, the latching auxiliary component applies an elastic restoring force to the latching actuator, thereby tending to move the latching structure to the latching position.

Description

Technical Field

[0001] The present application relates to an electrical connector, and more specifically, to an electrical connector that can be used with a circuit board. Background Art

[0002] Electronic products often use electrical connectors and circuit boards to transmit electrical signals or power signals. Generally speaking, the circuit board is electrically plugged into the electrical connector, and the electrical connector uses friction generated by contact with the circuit board to prevent the plugged circuit board from being separated from the electrical connector.

[0003] However, as electronic products continue to become thinner, the overall width of the circuit boards and their corresponding electrical connectors used within these products is being continuously reduced. Consequently, insufficient contact area between the circuit boards and their corresponding electrical connectors often results in insufficient friction, causing the circuit boards to easily separate from the plugged-in electrical connectors when subjected to external forces, potentially affecting the normal operation of the electronic product and even causing damage to the product.

[0004] Based on the above, how to provide an electrical connector to solve the various problems of circuit boards being easily separated from the plugged electrical connector when the electrical connector is used in electronic products is an urgent issue for people in the relevant technical field. Summary of the Invention

[0005] In view of the shortcomings of the above-mentioned prior art, the present application provides an electrical connector for use with a circuit board, the electrical connector comprising: an insulating base, the insulating base having a board plug-in structure, the board plug-in structure providing the circuit board with plug-in; a conductive terminal group, the conductive terminal group being embedded in the insulating base to provide an electrical connection to the circuit board plugged into the board plug-in structure; a snap-fit actuator, the snap-fit actuator having a snap-fit structure, an actuating structure and a rotating structure, the rotating structure being located between the snap-fit structure and the actuating structure, and the rotating structure being straddled across the insulating base, the actuating structure being able to actuate the rotating structure to rotate the rotating structure on the insulating base, so that the snap-fit structure can be moved to a snap-fit position or a non-snap-fit position, when the snap-fit structure moves When it reaches the locking position, the locking structure is locked and inserted into the circuit board of the plate plug-in structure. When the locking structure moves to the non-locking position, the locking structure releases the locking and insertion of the circuit board of the plate plug-in structure; and a locking auxiliary part, which provides assistance to the locking actuator and has an abutment structure and a limiting structure. The abutment structure abuts the actuating structure, and the limiting structure limits the movement of the rotating structure on the insulating seat to keep the rotating structure spanning the insulating seat. When the locking structure moves to the non-locking position, the actuating structure forces the abutment structure to elastically deform and generate an elastic restoring force. The elastic restoring force can provide the actuating structure to actuate the rotating structure so that the locking structure tends to move to the locking position.

[0006] With respect to the aforementioned electrical connector, the clamping auxiliary component can be selectively embedded in a side of the insulating base, and the clamping auxiliary component is a force-holding terminal, which is used to position the insulating base.

[0007] With respect to the aforementioned electrical connector, the clamping auxiliary component can be selectively embedded in the side of the insulating base, and the clamping auxiliary component is a shielding shell that provides a shielding environment for the electrical connection between the conductive terminal group and the circuit board.

[0008] With respect to the aforementioned electrical connector, the insulating base can optionally further have an accommodating groove for accommodating the rotating structure so that the rotating structure is arranged across the insulating base, and the limiting structure allows the rotating structure to be accommodated in the accommodating groove.

[0009] With respect to the aforementioned electrical connector, optionally, the rotating structure further has a penetration channel, and the penetration channel is provided to penetrate the abutting structure to prevent interference between the abutting structure and the rotating structure.

[0010] With respect to the aforementioned electrical connector, optionally, the abutting structure and the limiting structure are integrated into a fork-shaped structure.

[0011] For the aforementioned electrical connector, optionally, the insulating seat also has a first abutment structure. When the actuating structure moves to the dead point position, the first abutment structure provides abutment against the actuating structure to prevent the actuating structure from moving beyond a predetermined stroke, thereby forcing the abutment structure to undergo flexural deformation.

[0012] For the aforementioned electrical connector, the insulating seat can optionally also have a second abutment structure. When the abutment structure moves to a dead point position, the second abutment structure provides abutment against the abutment structure to prevent the abutment structure from moving beyond a predetermined stroke, thereby forcing the abutment structure to undergo flexural deformation.

[0013] With respect to the aforementioned electrical connector, optionally, when the rotating structure rotates, the engaging structure moves toward a first direction and the actuating structure moves toward a second direction, and the first direction is substantially different from the second direction.

[0014] With respect to the aforementioned electrical connector, optionally, the clamping auxiliary component further has a guiding structure, and the guiding structure provides guidance for the rotation of the rotating structure on the insulating base.

[0015] Compared to the prior art, the electrical connector of the present application can be used with a circuit board and is provided with a latching actuator and a latching auxiliary member. The latching actuator has a latching structure that can be moved to a latching position to latch the circuit board, thereby preventing the circuit board from being disengaged from the plugged electrical connector when subjected to external force. Furthermore, the latching actuator can be subjected to force to move the latching structure to a non-latching position to release the latching of the circuit board. When the latching structure moves to the non-latching position, the latching actuator forces the latching auxiliary member to elastically deform. At this time, the latching auxiliary member can apply an elastic restoring force to the latching actuator, thereby tending to move the latching structure to the latching position.

[0052] The following describes the technical content of this application through specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of this application from the content disclosed in this specification. This application may also be implemented or applied through other different specific embodiments. The details in this specification may also be modified and altered based on different viewpoints and applications without departing from the spirit of this application.

[0053] For the technical ideas of this application, please refer to Figures 1 to 24 The revelation.

[0054] like Figures 1 to 2 as well as Figure 13 As shown, the electrical connector 1 of the present application is used in conjunction with a circuit board 2. The circuit board 2 is, for example, a circuit board, a flexible circuit board or a flexible flat cable. Figure 5 as well as Figure 14 As shown, the electrical connector 1 of the present application includes an insulating base 11 , a conductive terminal set 12 , a snap-fitting actuator 13 and a snap-fitting auxiliary member 14 .

[0055] like Figure 11 As shown, the insulating base 11 is formed with a board plugging structure 111 for plugging in the circuit board 2. The conductive terminal assembly 12 is embedded in the insulating base 11 and is composed of at least one conductive terminal to provide an electrical connection to the circuit board 2 plugged into the board plugging structure 111 to transmit electrical signals or power signals from the circuit board 2.

[0056] like Figure 3In the embodiment shown, the engaging actuator 13 is made of an insulating material and comprises an integrally formed engaging structure 131, an actuating structure 132, and a rotating structure 133. In this embodiment, the rotating structure 133 is arranged across the insulating base 11, and the actuating structure 132 can actuate the rotating structure 133 upon receiving a force, causing the rotating structure 133 to rotate on the insulating base 11, so that the engaging structure 131 can be Figure 20 As shown, the locking structure 131 can be moved toward the first direction D1 to the locking position P1, or the locking structure 131 can be moved toward the first direction D1 to the locking position P1. Figure 21 As shown, it moves in the first direction D1 to the non-engaging position P2.

[0057] In addition, it should be noted that the actuating structure 132 may be exposed to provide a force-applying structure, so as to facilitate applying force to the actuating structure 132. Figures 20 to 21 As shown, since the rotating structure 133 is located between the clamping structure 131 and the actuating structure 132, when the rotating structure 133 rotates, if the clamping structure 131 moves toward the first direction D1, the actuating structure 132 will move toward the second direction D2, wherein the first direction D1 and the second direction D2 are substantially different. Figures 8 and 9 In the illustrated embodiment, the insulating base 11 is recessed with a receiving groove 112 , and the receiving groove 112 accommodates the rotating structure 133 , so that the rotating structure 133 can be arranged across the insulating base 11 .

[0058] The clamping auxiliary member 14 is embedded in the side of the insulating base 11 to provide assistance for clamping the actuator 13. Figure 4 In the embodiment shown, the clamping auxiliary component 14 has an abutment structure 141 and a limiting structure 142 formed as one piece, and the abutment structure 141 and the limiting structure 142 are integrated into a fork-shaped structure. Therefore, the abutment structure 141 extends below the rotating structure 133, and the limiting structure 142 extends above the rotating structure 133. In this embodiment, the abutment structure 141 is composed of an elastic arm to provide elastic abutment to the actuating structure 132, so that the limiting structure 142 provides limitation on the movement of the rotating structure 133 on the insulating base 11, so that the rotating structure 133 is accommodated in the accommodating groove 112 to prevent the rotating structure 133 from detaching from the insulating base 11, so as to keep the rotating structure 133 straddling the insulating base 11.

[0059] In addition, in order to ensure that the rotation of the rotating structure 133 on the insulating base 11 is in accordance with expectations, Figures 22 to 24 As shown, the clamping auxiliary component 14 may optionally be provided with a guide structure 143 to guide the rotation of the rotating structure 133 on the insulating base 11 through the guide structure 143 .

[0060] Regarding the structure of the clamping auxiliary member 14, Figure 5In the embodiment shown, the clamping auxiliary member 14 is a force-holding terminal for positioning the insulating seat 11. However, this is not limited to the embodiment shown. For example, Figure 14 In the illustrated embodiment, the auxiliary clamping member 14 is a shielding shell to provide a shielding environment for the electrical connection between the conductive terminal set 12 and the circuit board 2 .

[0061] It should be noted that if Figure 20 In the embodiment shown, when the clamping structure 131 moves to the clamping position P1, the clamping structure 131 clamps the circuit board 2 plugged into the board plug-in structure 111, as shown in FIG. Figure 21 In the embodiment shown, when the clamping structure 131 moves to the non-clamping position P2, the clamping structure 131 releases the clamping of the circuit board 2 plugged into the board plug-in structure 111. At this time, the circuit board 2 can be separated from the board plug-in structure 111. Figure 21 as well as Figure 23 In the embodiment shown, when the engaging structure 131 moves to the non-engaging position P2, the actuating structure 132 forces the abutting structure 141 to elastically deform to generate an elastic restoring force, which can drive the actuating structure 132 to actuate the rotating structure 133, so that the engaging structure 131 tends to move to the engaging position P1 (as shown in FIG. Figure 20 shown).

[0062] In this application, if Figures 18 to 21 As shown, the insulating base 11 may optionally include a first abutting structure 113. When the actuating structure 132 moves to a dead point, that is, when the movement of the actuating structure 132 is about to exceed a predetermined stroke, the first abutting structure 113 abuts against the actuating structure 132 to stop the continued movement of the actuating structure 132, preventing the actuating structure 132 from moving beyond the predetermined stroke, thereby forcing the abutting structure 141 to undergo flexural deformation. In addition, the insulating base 11 may optionally include a second abutting structure 114. When the abutting structure 141 moves to a dead point, that is, when the movement of the abutting structure 141 is about to exceed a predetermined stroke, the second abutting structure 114 abuts against the abutting structure 141 to stop the continued movement of the abutting structure 141, preventing the movement of the abutting structure 141 from exceeding the predetermined stroke, thereby forcing the abutting structure 141 to undergo flexural deformation.

[0063] The following describes the steps for assembling components of the electrical connector of this application. Figures 6 and 7 In the embodiment shown, first, the insulating base 11 and the conductive terminal group 12 are prepared separately, and then the conductive terminal group 12 is embedded in the insulating base 11 to form a first electrical connector semi-finished product S1. Figures 8 and 9 In the embodiment shown, the clamping actuator 13 is prepared and then the clamping actuator 13 is placed on the insulating base 11 to form the second electrical connector semi-finished product S2. Figures 10 and 11 As shown and Figures 15 and 16 In the embodiment, the clamping auxiliary member 14 is prepared, and then the clamping auxiliary member 14 is embedded in the side of the insulating seat 11. In addition, it should be noted that in the process of embedding the clamping auxiliary member 14 in the insulating seat 11, the abutting structure 141 will be close to the rotating structure 133. Figures 22 to 24 In the illustrated embodiment, the rotating structure 133 may optionally include a penetration channel 1331 for the abutting structure 141 to penetrate, so as to prevent the abutting structure 141 from interfering with the rotating structure 133 when the abutting structure 141 is close to the rotating structure 133 .

[0064] In summary, the present application provides an electrical connector for use with a circuit board. The provided electrical connector is provided with a latching actuator and a latching auxiliary member. The latching actuator has a latching structure that can be moved to a latching position to latch the circuit board, thereby preventing the circuit board from being disengaged from the plugged electrical connector when subjected to external force. Furthermore, the latching actuator can be subjected to force to move the latching structure to a non-latching position to release the latching of the circuit board. When the latching structure moves to the non-latching position, the latching actuator forces the latching auxiliary member to elastically deform. At this time, the latching auxiliary member can apply an elastic restoring force to the latching actuator, thereby tending to move the latching structure to the latching position.
