Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-speed connector with a pre-alignment guide pin. Background Technology

[0002] High-speed connectors are key components for achieving high-speed signal transmission in modern electronic devices, and their applications are becoming increasingly widespread and in-depth. In particular, in fields such as servers, communication equipment, and data centers, the reliability requirements for connectors are extremely high. These connectors typically integrate a large number of high-density precision terminals to meet the huge data throughput demands.

[0003] In actual assembly and use, mating two connector halves covered with precision terminals is a challenging operation. Due to the small size and close arrangement of the terminals, operators are prone to misalignment when aligning them by eye and touch without effective guidance. If misalignment is forced in, it can lead to terminal bending and deformation, affecting signal quality, or even terminal breakage, rendering the entire connector and even the equipment unusable. This not only increases production and maintenance costs but also reduces operational efficiency.

[0004] While some connectors have simple guide pins, these guide structures often only provide initial orientation guidance and lack a mechanism to confirm alignment and provide initial locking before precision terminal contact. Operators cannot obtain clear feedback on the alignment, and there is still a risk of misoperation.

[0005] Therefore, this invention proposes a high-speed connector with a pre-alignment guide pin to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of alignment difficulties, damage to precision terminals due to misalignment during insertion and removal, and lack of reliable pre-alignment locking mechanism in existing high-speed connectors, this utility model aims to provide a high-speed connector with pre-alignment guide pins that has an improved structure and can effectively solve the above problems.

[0007] This utility model provides a high-speed connector with a pre-alignment guide pin, including a first support plate, a first connector fixed on the first support plate, a second support plate, and a second connector fixed on the second support plate; it also includes a pre-guide component.

[0008] The preguided assembly includes a second housing disposed above the first connector, a first housing disposed above the second connector, a support piece disposed inside the first housing, a stop block fixed to the second housing, and a first spring.

[0009] Furthermore, the first housing and the second housing are combined by a sliding fit, the first spring is disposed between the support plate and the first housing, and the stop is adapted to press the support plate to compress the first spring when the first housing slides into the second housing. Through this structural combination, the mechanical structure is pre-aligned and locked before the precision terminals of the first connector and the second connector come into contact with each other.

[0010] Preferably, the support plate has a groove, and the stop block enters the groove after pressing the support plate and passing over it. This structure forms a clear locking mechanism, providing clear physical feedback to the operator.

[0011] Preferably, the high-speed connector with pre-alignment guide pin further includes a reinforcing fixing component, which is mounted on the second support plate. Meanwhile, the first support plate is provided with a corresponding groove for engaging the reinforcing fixing component, providing a second locking after connection.

[0012] Preferably, the reinforcing and fixing assembly includes a support rod and a support body. The support rod is fixed to the outer wall of the second support plate, while the support body is fixed to the support rod, providing a stable mounting base for other moving parts of the reinforcing and fixing assembly.

[0013] Preferably, in order to perform the locking action, the reinforcing fastening component further includes at least two sliders, which are symmetrically slidably disposed in grooves inside the support body.

[0014] Preferably, the reinforcing fixing assembly further includes a baffle and at least two second springs, the baffle serving as a fixing base for the springs, and the second springs providing driving force for the movement of the slider.

[0015] Preferably, in order to form a complete elastic drive mechanism, both ends of each second spring are fixedly connected between the corresponding slider and the baffle.

[0016] Preferably, each of the second springs elastically pushes the corresponding slider toward a direction away from the center of the support. This outward pushing structure allows the slider to be locked in the groove of the first support plate, thereby achieving a firm and reinforced fixation.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of difficult alignment of high-speed connectors and easy damage to precision terminals due to misalignment during insertion and removal in the prior art by setting a pre-guided assembly consisting of a first outer shell, a second outer shell, a support plate, a first spring, and a stop block. It achieves the effect of guiding and positioning first and then electrical connection, effectively protecting the connector, simplifying operation, and improving the accuracy of docking.

[0018] 2. This utility model, by setting up a reinforced fixing component consisting of a support body, a slider, and a second spring, can achieve self-locking through the rebound of the slider after the connector is connected. This solves the problem in the prior art that the connector is not reliably fixed after connection and is prone to loosening in a vibration environment, thus affecting the stability of signal transmission. It achieves the effect of double mechanical locking, enhances the vibration and impact resistance of the connection, and ensures the long-term reliability of high-speed signal transmission.

[0019] 3. This utility model, by modularly separating the pre-guiding function and the reinforcing and fixing function, forms a step-by-step connection process, which solves the problems of simple connector structure, low functional integration and poor overall reliability in the prior art. It achieves a comprehensive technical effect of clear structure, distinct action levels, convenient operation and safety and reliability, improves the overall performance of the product and extends its service life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 This utility model provides a high-speed connector with a pre-alignment guide pin, which aims to solve the problems in the prior art where connector alignment is difficult, leading to terminal damage, and the fixed structure after docking is not stable enough and is prone to loosening in a vibration environment.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the high-speed connector with pre-alignment guide pin includes a first support plate 3, a first connector 1 fixed on the first support plate 3, a second support plate 4, and a second connector 2 fixed on the second support plate 4. The first connector 1 and the second connector 2 are adapted to mate with each other.

[0025] This high-speed connector also includes a pre-guided assembly 5, please refer to... Figure 1 and Figure 3 The preguide assembly 5 includes a second housing 504 disposed above the first connector 1 and a first housing 501 disposed above the second connector 2. The second housing 504 can slidably accommodate the first housing 501. The preguide assembly 5 also includes a support piece 502 disposed inside the first housing 501, a stop block 505 fixed on the second housing 504, and a first spring 503. The first spring 503 is disposed between the support piece 502 and the first housing 501. When the first housing 501 slides into the second housing 504, the stop block 505 is adapted to press the support piece 502 to compress the first spring 503. The support piece 502 is provided with a groove. After pressing the support piece 502 and passing over the support piece 502, the stop block 505 enters the groove.

[0026] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The high-speed connector also includes a reinforcing fixing component 6, which is mounted on the second support plate 4. The first support plate 3 has a corresponding groove for engaging the reinforcing fixing component 6. The reinforcing fixing component 6 includes a support rod 601, which is fixed to the outer wall of the second support plate 4. The reinforcing fixing component 6 also includes a support body 602, which is fixed to the support rod 601. The reinforcing fixing component 6 also includes at least two sliders 603, which are slidably disposed within the support body 602. The reinforcing fixing component 6 also includes a baffle 605 and at least two second springs 604, each of which is fixed between the corresponding slider 603 and the baffle 605. Each second spring 604 elastically pushes the corresponding slider 603 to move away from the support body 602, so that the slider 603 is engaged in the groove of the first support plate 3.

[0027] The pre-guided assembly 5 includes a second housing 504 disposed above the first connector 1 and a first housing 501 disposed above the second connector 2. The first housing 501 is fixed to the first support plate 3 via the second connector 2, and the second housing 504 is fixed to the second support plate 4 via the first connector 1. The second housing 504 has an internal cavity that can slidably accommodate the first housing 501. This sliding fit structure between the housings provides preliminary alignment guidance when the first support plate 3 and the second support plate 4 are close together.

[0028] To achieve precise pre-locking, the pre-guided assembly 5 also includes a support piece 502 disposed inside the first housing 501, a stop block 505 fixed on the second housing 504, and a first spring 503. The first spring 503 is disposed between the support piece 502 and the inner wall of the first housing 501 and is used to elastically push the support piece 502. The support piece 502 has a groove corresponding to the position of the stop block 505. In the assembled state, when the first housing 501 slides into the second housing 504, the stop block 505 contacts and presses the support piece 502, forcing the support piece 502 to retract inward against the elastic force of the first spring 503, thereby compressing the first spring 503. When the first housing 501 slides into place, the stop block 505 moves exactly to the groove of the support piece 502. At this time, the first spring 503 releases its elastic force to push the support piece 502 to reset, so that the stop block 505 is locked into the groove, ensuring that the entire connector has completed a firm mechanical pre-alignment and positioning before the precision terminals of the first connector 1 and the second connector 2 make contact.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to achieve reliable locking of the pre-guided component 5, please refer to... Figure 3The support plate 502 has a groove, the shape and depth of which match the stop block 505. When the stop block 505 presses the support plate 502 and passes over the support plate 502, it enters the groove. The first spring 503 pushes the support plate 502 to reset, so that the stop block 505 is firmly held in the groove.

[0030] As another preferred embodiment, to provide a more secure mechanical fixation after connector mating, please refer to... Figure 1 and Figure 2 The high-speed connector also includes a reinforcing fixing component 6, which is mounted on the second support plate 4. The first support plate 3 has a corresponding groove for engaging the reinforcing fixing component 6.

[0031] In a specific structure, please refer to Figure 4 The reinforcing and fixing component 6 includes a support rod 601, which is fixed to the outer wall of the second support plate 4. The reinforcing and fixing component 6 also includes a support body 602, which is fixed to the support rod 601.

[0032] To perform the locking action, please refer to... Figure 4 The reinforcing fixing component 6 also includes at least two sliders 603, which are symmetrically slidably disposed within the support body 602.

[0033] To provide the return spring force for slider 603, please refer to... Figure 5 The reinforcing fastening component 6 also includes a baffle 605 and at least two second springs 604.

[0034] In a preferred assembly relationship, the two ends of each second spring 604 are fixed between the corresponding slider 603 and the baffle 605, and each second spring 604 is in a pre-compressed state to elastically push the corresponding slider 603 to move away from the center of the support body 602. This structure makes the slider 603 tend to pop outward so that it can be inserted into the groove of the first support plate 3 after docking.

[0035] The working principle of this high-speed connector with a pre-alignment guide pin is as follows: When connection and fixation are required, the first support plate 3 and the second support plate 4 approach each other. At this time, the pre-guide component 5 first plays its role. Its first outer shell 501 begins to slide into the internal cavity of the second outer shell 504. During the sliding process, the stop block 505 fixed on the second outer shell 504 contacts and presses the support piece 502 inside the first outer shell 501. After being pressed, the support piece 502 overcomes the elastic force of the first spring 503 and moves inward, thereby compressing the first spring 503. When the first outer shell 501 is fully inserted into the predetermined position of the second outer shell 504, the stop block 505 just moves to the groove of the support piece 502. The compressed first spring 503 relaxes and resets, pushing the support piece 502, so that the stop block 505 enters and is locked in the groove. Through this synergistic effect, the problem of alignment difficulty is solved before the first connector 1 and the second connector 2 are docked.

[0036] After the pre-guiding is completed and the first connector 1 and the second connector 2 are fully connected, the reinforcing fixing component 6 comes into play. At this time, at least two sliders 603 can be pressed, causing the sliders 603 to slide within the support body 602 and compress at least two second springs 604 fixed between the sliders 603 and the baffle 605. When the reinforcing fixing component 6 is fully inserted into the groove of the first support plate 3, the sliders 603 are released. The sliders 603 are subjected to the rebound force of the second springs 604, and at least two sliders 603 move away from the support body 602, finally firmly stuck on the inner wall of the groove of the first support plate 3, completing the final reinforcing fixing and solving the problem of easy loosening after connection.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
