Description

Technical Field

[0001] The present utility model relates to a connector assembly, and more particularly to a vertical pluggable connector assembly. Background Art

[0002] To achieve electrical connection between different electronic devices, various forms of electrical connectors have been developed. Electrical connectors can be classified into wire-end connectors and board-end connectors according to their installation positions. The wire-end connector is located at one end of a cable and is used to mate with the board-end connector, while the board-end connector is disposed on a circuit board. With the continuous progress and innovation of technologies for various electronic products, the performance of new electronic products has been significantly improved, the types of electrical signals have become more diverse, and more bandwidth is required.

[0003] Wire-end connectors and board-end connectors often require additional complex positioning elements. When the wire-end connector is detached from the board-end connector, the user may need to perform multiple operation steps to unlock the positioning elements before the wire-end connector can be pulled out from the board-end connector. Therefore, wire-end connectors and board-end connectors with quick plugging and unplugging functions are important topics for those skilled in the art. Summary of the Utility Model

[0004] According to some embodiments of the present utility model, a connector assembly includes a wire-end connector and a board-end connector. The wire-end connector includes an insulating body and a snap element. Opposite outer sidewalls of the insulating body each have a protrusion. The snap element extends from one of the two outer sidewalls of the insulating body to the other. Opposite sides of the snap element each have an abutting portion, and the abutting portion is adjacent to the protrusion. The board-end connector includes a circuit board and a positioning frame on the circuit board. Opposite inner sidewalls of the positioning frame each have a limiting hook portion. When the wire-end connector is mated with the board-end connector, the limiting hook portion is located on the abutting portion of the snap element and the protrusion of the insulating body to limit the insulating body. When an upward force is applied to the snap element, the abutting portion moves upward to push the limiting hook portion outward, causing the limiting hook portion to disengage from the protrusion and release the insulating body.

[0005] In some embodiments, the above-mentioned snap element has a flat portion. The flat portion covers the top surface of the insulating body and protrudes beyond the edge of the insulating body.

[0006] In some embodiments, the flat portion of the above-mentioned snap element extends horizontally beyond the positioning frame, so that a part of the flat portion overlaps with the positioning frame in the vertical direction.

[0007] In some embodiments, each of the two outer sidewalls of the above-mentioned insulating body has a groove, and each end of the snap element has a hook, and the hook is located below the groove. When an upward force is applied to the snap element, the hook is configured to abut against the groove to apply an upward force to the insulating body.

[0008] In some embodiments, the abutting portion of the above-mentioned snap element has an arc surface, and this arc surface protrudes away from the insulating body.

[0009] In some embodiments, the arc surface of the above-mentioned abutting portion protrudes towards one of the two inner side walls of the positioning frame.

[0010] In some embodiments, a part of the limiting hook portion of the above-mentioned positioning frame overlaps with the abutting portion of the snap element in the vertical direction.

[0011] In some embodiments, a part of the limiting hook portion of the above-mentioned positioning frame overlaps with the convex portion of the insulating body in the vertical direction.

[0012] In some embodiments, the above-mentioned snap element has a strip portion, and this strip portion straddles the top surface of the insulating body.

[0013] In some embodiments, the above-mentioned wire-end connector further includes a pull strap. The pull strap is connected to the strip portion of the snap element.

[0014] In the above-mentioned embodiments of the present utility model, since the snap element of the wire-end connector has an abutting portion, the insulating body has a convex portion adjacent to the abutting portion, and the positioning frame of the board-end connector has a limiting hook portion, when the wire-end connector is mated with the board-end connector, the limiting hook portion can be on the abutting portion of the snap element and the convex portion of the insulating body, achieving the effect of limiting in the vertical direction. In addition, when the wire-end connector needs to be released from the board-end connector, an upward force can be applied to the snap element, so that the abutting portion of the snap element moves upward and pushes the limiting hook portion of the positioning frame outward. In this way, the limiting hook portion of the positioning frame can be disengaged from the convex portion of the insulating body to release the insulating body. This connector assembly can unlock and release the wire-end connector only by operating steps of applying an upward force to the snap element, and this step can also synchronously pull out the wire-end connector from the board-end connector, which is beneficial to quick plugging and unplugging, and can effectively reduce costs and improve product competitiveness.

[0028] Figure 1 Shows an exploded view of a connector assembly 300 according to an embodiment of the present utility model. Figure 2 Shows Figure 1Combined perspective view of the connector assembly 300. Refer also to Figure 1 and Figure 2 , the connector assembly 300 includes a wire-end connector 100 and a board-end connector 200. The wire-end connector 100 includes an insulating body 110 and a latching element 120. The insulating body 110 is connected to one end of the cable 130. Opposite outer sidewalls of the insulating body 110 each have a protrusion 112. The latching element 120 extends from one of the two outer sidewalls of the insulating body 110 to the other. That is, the latching element 120 at least partially covers the top surface of the insulating body 110. Opposite sides of the latching element 120 each have an abutting portion 122, and the abutting portion 122 of the latching element 120 is adjacent to the protrusion 112 of the insulating body 110. The board-end connector 200 includes a circuit board 210 and a positioning frame 220, and the positioning frame 220 is located on the circuit board 210. Opposite inner sidewalls of the positioning frame 220 each have a limiting hook portion 222.

[0029] In some embodiments, the connector assembly 300 is a vertically pluggable connector assembly. The material of the insulating body 110 can be plastic. The latching element 120 can be an integrally formed part, such as a metal part formed by stamping, but the material of the latching element 120 is not limited to metal. The limiting hook portion 222 of the positioning frame 220 has elasticity and can be extruded to move outward and reset inward after the pressure is removed. Figure 1 The wire-end connector 100 can move downward to be mated with the board-end connector 200 to become Figure 2 the state. During the downward movement of the wire-end connector 100, the protrusion 112 of the insulating body 110 and the abutting portion 122 of the latching element 120 can push the limiting hook portion 222 of the positioning frame 220 to move it outward, and then the protrusion 112 and the abutting portion 122 can pass through the limiting hook portion 222.

[0030] In addition, in this embodiment, the latching element 120 has a flat plate portion 126. The flat plate portion 126 covers the top surface of the insulating body 110 and protrudes beyond the edge of the insulating body 110 to facilitate the user to apply force (to be described in Figure 6 ). After the wire-end connector 100 and the board-end connector 200 are mated, the flat plate portion 126 of the latching element 120 extends in the horizontal direction D1 and exceeds the positioning frame 220, so that a part of the flat plate portion 126 overlaps with the positioning frame 220 in the vertical direction D2.

[0031] Figure 3 Illustrates Figure 2 Cross-sectional view of the connector assembly 300 along line 3-3. Figure 4 Illustrates Figure 3 Partial enlarged view of the connector assembly 300. Refer also to Figure 3 and Figure 4, when the abutting portion 122 of the convex portion 112 of the insulating body 110 and the fastening element 120 (see Figure 1 ) passes downward through the limiting hook portion 222, the limiting hook portion 222 will reset due to its own elasticity, so that the limiting hook portion 222 is located on the convex portion 112 of the insulating body 110 to limit the insulating body 110.

[0032] Figure 5 Shown Figure 2 Partial enlarged sectional view of the connector assembly 300 along line 5-5. Also refer to Figure 4 And Figure 5 , in addition, in the Figure 4 state, that is, when the wire-end connector 100 is mated with the board-end connector 200, the limiting hook portion 222 is not only located on the convex portion 112 of the insulating body 110, but also located on the abutting portion 122 of the fastening element 120 at the same time. In this embodiment, a part of the limiting hook portion 222 of the positioning frame 220 overlaps with the abutting portion 122 of the fastening element 120 in the vertical direction D2, and another part of the limiting hook portion 222 overlaps with the convex portion 112 of the insulating body 110 in the vertical direction D2. In other words, the limiting hook portion 222 extends from the convex portion 112 of the insulating body 110 to the abutting portion 122 of the fastening element 120 (also visible in Figure 2 ).

[0033] Specifically, since the fastening element 120 of the wire-end connector 100 has an abutting portion 122, the insulating body 110 has a convex portion 112 adjacent to the abutting portion 122, and the positioning frame 220 of the board-end connector 200 has a limiting hook portion 222, so when the wire-end connector 100 is mated with the board-end connector 200, the limiting hook portion 222 of the positioning frame 220 can be on the abutting portion 122 of the fastening element 120 and the convex portion 112 of the insulating body 110 to achieve the effect of limiting in the vertical direction D2.

[0034] In this embodiment, the abutting portion 122 of the fastening element 120 has an arc surface 123, and the arc surface 123 protrudes away from the insulating body 110. That is to say, the arc surface 123 of the abutting portion 122 protrudes toward the inner side wall of the positioning frame 220. In addition, the outer side wall of the insulating body 110 has a groove 114, one end of the fastening element 120 has a hook 124, and the hook 124 of the fastening element 120 is located below the groove 114 of the insulating body 110.

[0035] In the following description, the process of unlocking and releasing the wire-end connector 100 from the board-end connector 200 will be described.

[0036] Figure 6 Shown Figure 2 Schematic diagram of the operation of the connector assembly 300 shown. Figure 7 ShownFigure 5 Schematic diagram of the connector assembly 300 during operation. Figure 6 and Figure 7 When the line-end connector 100 needs to be released from the board-end connector 200, the user can use his hand to apply an upward force (e.g., in the vertical direction D2) to the flat plate portion 126 of the buckle element 120, so that the contact portion 122 of the buckle element 120 moves upward and the arc surface 123 pushes the limiting hook portion 222 of the positioning frame 220 outward (e.g., in the direction D3). In this way, the limiting hook portion 222 of the positioning frame 220 can be separated from the protrusion 112 of the insulating body 110 (see Figure 4 ) to release the insulating body 110. At this time, the buckle element 120 is continuously exerted with an upward force, and the hook 124 of the buckle element 120 can abut against the groove 114 of the insulating body 110 to exert an upward force on the insulating body 110, thereby separating the line end connector 100 from the board end connector 200.

[0037] Through the above configuration, the connector assembly 300 can unlock and release the line-end connector 100 simply by applying an upward force to the latch element 120, and this step can also simultaneously unplug the line-end connector 100 from the board-end connector 200, which is conducive to quick plugging and unplugging, and can effectively reduce costs and enhance product competitiveness.

[0038] It should be understood that the connection relationship, materials and functions of the components described above will not be repeated, and will be described first. In the following description, other types of connector components will be described.

[0039] Figure 8 A three-dimensional view of a connector assembly 300 a according to another embodiment of the present invention is shown. Figure 9 Draw Figure 8 A side view of the connector assembly 300a is shown. Figure 8 and Figure 9 The connector assembly 300a includes a line-end connector 100a and a board-end connector 200. The line-end connector 100a includes an insulating body 110 and a buckle element 120a. Figure 2 The difference between the embodiments is that the buckle element 120a of the line end connector 100a has a strip portion 128 but no flat plate portion 126 (see FIG. Figure 6 ), and the line end connector 100a further includes a pull strap 129 connected to the strip portion 128. In this embodiment, the strip portion 128 of the buckle element 120a spans across the top surface of the insulating body 110.

[0040] Figure 10 Draw Figure 9 Schematic diagram of the operation of the connector assembly 300a. Figure 9 and Figure 10, the process of unlocking and releasing the wire - end connector 100a from the board - end connector 200 is similar to the process from Figure 4 , Figure 5 state to Figure 7 state. The difference in this embodiment is that when the wire - end connector 100a needs to be released from the board - end connector 200, the user applies an upward force (e.g., in the vertical direction D2) to the pulling strap 129 of the buckle element 120a, instead of directly applying a force to the Figure 6 flat plate portion 126. With such a design, the pulling strap 129 can drive the strip - shaped portion 128 and the abutting portion 122 of the buckle element 120a to move upward, and push the limiting hook portion 222 of the positioning frame 220 outward (see Figure 7 ) to release the insulating body 110. At this time, the hook 124 of the buckle element 120a can further abut against the groove 114 of the insulating body 110 (see Figure 7 ) and continue to apply an upward force to the insulating body 110, thereby separating the wire - end connector 100a from the board - end connector 200.

[0041] The foregoing has outlined the features of several embodiments, enabling those skilled in the art to better understand the aspects of the present utility model. Those skilled in the art should understand that they can easily use the present utility model as a basis for designing or modifying other processes and structures to achieve the same purposes and / or achieve the same advantages as the embodiments described herein. Those skilled in the art should also recognize that such equivalent structures do not depart from the spirit and scope of the present utility model, and they can be variously changed, substituted, and altered herein without departing from the spirit and scope of the present utility model.
