Description

Technical Field

[0001] The present invention belongs to the technical field of high-speed connectors, and particularly relates to a pull-tape locking structure and a high-speed connector assembly using the pull-tape locking structure. Background Art

[0002] With the development of high-speed connectors towards miniaturization, high density, and high speed, combined with the application scenarios of miniaturized high-speed connectors, the installation environment has a narrow space, making it difficult to perform unlocking operations. For example, in the prior art, CN113422248B discloses a high-speed connector assembly and its latch. As Figures 1 to 2 shown, the latch 01 has a U-shaped sheet structure and is provided on both sides of the high-speed connector plug 001 for cooperation with the corresponding locking grooves 02 on both sides of the high-speed connector socket 002 to achieve the locking function. When unlocking, a button type is used to release the locking state between the high-speed connector plug 001 and the high-speed connector socket 002. Since the latch 01 is provided on both sides in the width direction of the high-speed connector plug 001, when pressing to unlock, an unlocking space for easy pressing force application needs to be reserved in the width direction of the connector. Therefore, it is not easy to insert and remove in a narrow space, and it is not conducive to the high-density deployment of high-speed connectors in the width direction. Summary of the Invention

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0049] Embodiment of a high - speed connector assembly:

[0050] Please refer to Figures 3 to 12 , a high - speed connector assembly, including a plug 1 and a socket 2 that are adaptively inserted. The plug 1 includes a plug housing 11, a plug insulator 12 provided in the plug housing, plug contacts 13 arranged in rows in the plug insulator, and a coaxial cable 14 connected to the plug contacts. The socket 2 includes a socket housing 21, a socket insulator 22 provided in the socket housing, and socket contacts 23 arranged in rows in the socket insulator.

[0051] The plug 1 is provided with a strap locking structure, which includes a strap 15 and a spring piece 16. Among them, two spring pieces 16 are symmetrically arranged on both sides of the plug housing 11, and each spring piece 16 is configured with a strap 15. The spring piece 16 extends along the height direction of the plug 1, that is, the spring piece 16 extends along the plug insertion and extraction direction. For the convenience of description, the extension direction of the spring piece is defined as the up and down direction. In this embodiment, the spring piece 16 and the plug housing 11 are integrally formed. The spring piece 16 is formed by bending and extending the side part of the upper surface of the plug housing 11 downward, and the lower end of the spring piece 16 extends downward to protrude from the lower surface of the plug housing 11. A lock hole 161 is formed on the spring piece 16 for the clamping point 24 provided on the socket housing 21 to fall into, and the clamping point 24 and the lock hole 161 are in a snap connection, and the two are hooked and matched in the head and socket separation direction to realize the locking of the head and socket. A beam 162 is provided at the position of the spring piece 16 above the lock hole. The beam 162 is used to connect with one end of the corresponding strap 15. One end of the strap 15 is tied to the beam 162 to facilitate pulling the beam during the unlocking process to deform the spring piece; the end of the strap 15 connected to the spring piece is in a ring structure 151, and the beam 162 passes through the ring structure. The lower end of the spring piece 16 is a movable end, and the movable end has a guiding inclined surface 163. The guiding inclined surface 163 guides and cooperates with the clamping point when starting to contact, so that the spring piece is easily deformed toward the inner side direction of the plug housing; and the upper end of the spring piece is the fixed end integrally formed with the plug housing.

[0052] A through hole 111 for the other end of the corresponding strap 15 to pass through is formed on both sides of the upper surface of the plug housing 11. The other end of the strap 15 is provided with an unlocking force application end 152; the arrangement direction of the through hole 111 and the lock hole 161 is perpendicular to each other, and the two are offset in the plug contact arrangement direction. When unlocking, pull the two straps 15 upward at the same time, then the spring pieces 16 on both sides will be synchronously deformed toward the inner side direction of the plug housing under the pulling of the straps, so that the clamping points on both sides simultaneously withdraw from the corresponding lock holes.

[0053] As Figure 6 shown, insulator holes 121 corresponding to the through holes 111 are formed on both sides of the plug insulator 12, and the insulator holes 121 are located below the through holes on the same side. At this time, one end of the strap is connected to the spring piece, and the other end passes through the insulator hole 121 and the through hole 111 in sequence and is arranged above the plug housing 11. Due to the arrangement of the insulator holes 121, a strap pressing part 122 is formed on one side of the insulator hole 121 close to the spring piece 16 on the same side. The lower guiding surface 123 of the strap pressing part 122 slides and cooperates with the strap during the unlocking process. The lower guiding surface 123 extends in the left and right direction, and the left and right direction is the plug contact arrangement direction, and the left and right direction is also the width direction of the plug housing. Therefore, when pulling the strap upward, it is beneficial to generate a horizontal force toward the inner side direction of the plug housing, which is beneficial to the deformation and unlocking of each spring piece 16 toward the inner side direction.

[0054] Further, a spring piece avoidance hole 221 is provided on each side of the socket insulator 22. The spring piece avoidance hole 221 is located inside the clamping point 24 on the same side to facilitate the entry of the spring piece when the head seat is inserted and locked. In addition, convex structures 124 are symmetrically arranged on both sides of the lower surface of the plug insulator 12. When the head seat is inserted, the convex structures 124 enter the spring piece avoidance holes 221 on the corresponding sides. During the insertion process, the convex structures 124 and the inner walls of the spring piece avoidance holes 221 are in guiding sliding fit in the up and down direction. After the insertion is in place, the convex structures 124 and the relatively arranged inner walls 2211 in the spring piece avoidance holes 221 are in blocking fit in the front and back direction (the coaxial cable extension direction), which is beneficial to strengthening the locking stability state of the spring piece 16 and the clamping point 24, equivalent to realizing the insertion limit of the plug insulator 12 and the socket insulator 22, and providing a locking strengthening structure near the cooperation area of the spring piece 16 and the clamping point 24.

[0055] Combined Figure 8 In this embodiment, the clamping point 24 is a card structure formed by bending the socket housing towards its inner side. The card structure has a certain elastic deformation ability. Therefore, when the lower end of the spring piece contacts it, the card structure will have a slight tendency to deform towards the outer side of the socket housing, which is beneficial to reducing the insertion force. In addition, after locking, the card structure also has a large locking force and is not conducive to natural unlocking, so it can adapt to the vibration environment and prevent accidental unlocking. In other embodiments, convex structures such as convex bumps can also be used, but the locking effect is not as good as the card structure in this embodiment.

[0056] The insertion, locking and unlocking processes of the plug and the socket are as follows:

[0057] As Figure 9 、 Figure 10 shown, the socket is fixed on the PCB board. The plug is inserted downward into the socket. The spring pieces on both sides of the plug housing are deformed towards the inner side. When the clamping points on both sides of the socket housing enter the corresponding lock holes, the head seat is locked.

[0058] When unlocking, pull the pull belt upward. Since the through hole and the lock hole are misaligned in the width direction of the plug housing (the arrangement direction of the plug contacts), the pull belt can apply a force towards the inner side of the plug housing to the spring piece, so that the two pull belts can drive the spring piece to deform respectively, further separating the clamping point and the spring piece to achieve unlocking.

[0059] Embodiment of the pull belt locking structure:

[0060] The pull belt locking structure is the pull belt locking structure described in the above embodiment of the high-speed connector assembly, which will not be elaborated here.

[0061] The above are only the preferred embodiments of the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
