Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a connector protection structure. Background Technology
[0002] With the development of the automotive industry, people have increasingly higher requirements for vehicle safety and functionality, leading to the emergence of various terminal structures. This necessitates corresponding sheath structures to adapt to them. Due to structural limitations, some connectors cannot have their terminal hole openings made into complete guiding structures.
[0003] The difference between this type of connector and a conventional connector is that the connector terminals are attached to the sheath spring structure. Due to the molding of the spring structure and the need for terminal unlocking, a portion of the structure needs to be removed from the upper wall of the cavity on the side where the sheath spring is installed, resulting in an incomplete square hole for the terminal. The terminals are exposed and lack protection, which makes them prone to misalignment during connector mating. This risk increases the connector's mating force and can damage the terminal structure.
[0004] Currently, there is a lack of protective measures for this type of sheath structure on the market, and a new type of connector protective sheet structure needs to be designed to solve the above technical problems. Summary of the Invention
[0005] To address the aforementioned technical problems, this utility model proposes a novel connector protection structure to solve the problem in the prior art where incomplete terminal cavity holes in a certain connector result in exposed components lacking protection.
[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A novel connector protection structure includes a protective plate connected to a socket sleeve. The protective plate has a guide hole that aligns with and communicates with a cavity hole on the socket sleeve for a pin to pass through. The protective plate is clamped between the socket sleeve and the pin sleeve. This invention, by placing a protective plate between the socket sleeve and the pin sleeve, and providing a guide hole for the pin to pass through, limits the pin's position, preventing the risk of misalignment when the pin is inserted into an incomplete cavity hole, and also preventing the pin from easily wobbling.
[0007] Furthermore, to facilitate the connection between the protective sheet and the socket sleeve, the protective sheet and the socket sleeve are snapped together.
[0008] Furthermore, the protective sheet has hooks A at both ends, and the socket sleeve has hook points A that cooperate with the hooks A.
[0009] Furthermore, guide plates are provided on both sides of the nose clip A, and guide grooves that fit the guide plates are provided on the socket sleeve.
[0010] Furthermore, a guardrail is provided on the lower side of the protective sheet, and a mating part that abuts against the guardrail is provided on the socket sleeve to prevent deformation of the protective sheet.
[0011] Furthermore, the guardrail is positioned near the end of the protective plate, and the outer side of the socket sleeve has a right-angle mating part that abuts against the inner side of the guardrail and the side of the guardrail near the end of the protective plate.
[0012] Furthermore, the outer side of the socket sheath is provided with a hook B, and the pin sheath is provided with a hook point B that mates with the hook B.
[0013] Furthermore, the lower side of the nose clip B is provided with a pressing arm for pressing the nose clip B to disengage the nose clip B from the hanging point B.
[0014] Furthermore, the outer side of the socket sheath is provided with two downwardly extending cantilever arms, the hook B is connected between the two cantilever arms, and the pressing arm is connected to the lower end of the two cantilever arms; the pin sheath is provided with a vertical anti-misalignment rib B, and the anti-misalignment rib B and the hook point B form an anti-misalignment gap that fits with the cantilever arms.
[0015] Furthermore, a TPA is inserted into the socket sleeve, and the inner end of the TPA abuts against the terminal box; the socket sleeve has a protrusion, and the end of the TPA has two hanging points C that can cooperate with the protrusion one after the other to form a pre-installation position and a fixed position.
[0016] The beneficial effects of this utility model are: 1. This utility model provides a protective plate between the socket sleeve and the pin sleeve. The protective plate has a guide hole for the pin to pass through, which limits the pin and avoids the risk of the pin being inserted at an angle after being inserted into an incomplete cavity hole. It also prevents the pin from shaking easily. 2. This utility model connects the protective sheet and the socket cover by setting a hanging nose A on the protective sheet to cooperate with the hanging point A of the socket cover; 3. This utility model provides a guardrail on the underside of the protective sheet. After being installed on the protective sleeve, the guardrail provides a certain anti-sway function. In addition, the guardrail can correct the deformation of the protective sheet after long-term use. Attached Figure Description

[0020] 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.
[0021] like Figure 1 As shown in Embodiment 1 of this utility model, a novel connector protection structure includes a protective sheet 2 connected to a socket sleeve 1, and the protective sheet 2 is clamped between the socket sleeve 1 and the pin sleeve 3. Figure 3 As shown, the protective plate 2 has a guide hole 2-5 that aligns with and communicates with the cavity hole on the socket sleeve 1, so that the pin first passes through the guide hole 2-5 on the protective plate 2 and then enters the cavity hole on the socket sleeve 1 to abut against the spring latch. Figure 5 As shown. Because the upper part of the cavity wall connecting the spring is missing, the spring has a large margin of elastic movement. The guide hole 2-5 forms a limit at the middle of the insert pin, preventing the insert pin from being inserted at an angle or shifting.
[0022] Example 2 differs from Example 1 in that the protective sheet 2 is snapped into the socket sleeve 1.
[0023] Specifically, such as Figure 3 As shown, the protective sheet 2 has hooks A2-1 at both ends. Figure 2 As shown, the socket sleeve 1 has a hanging point A1-1 that mates with the hook A2-1. The hook A2-1 has a hanging groove in the middle that hangs on the raised hanging point A1-1, thus connecting the protective piece 2 and the socket sleeve 1.
[0024] Example 3 differs from Example 2 in that, as Figure 3 As shown, guide plates 2-4 are provided on both sides of the nose clip A2-1, and the guide plates 2-4 and the nose clip A2-1 are a single unit. Figure 2 As shown, the socket sleeve 1 is provided with a guide groove 1-7 that fits with the guide piece 2-4. The hanging point A1-1 is located in the middle of the guide groove 1-7 and cooperates with the hanging lug A2-1 between the guide piece 2-4 inserted into the guide groove 1-7.
[0025] Example 4 differs from Example 3 in that, as Figure 3 As shown, the lower side of the protective sheet 2 is provided with a guardrail 2-2, and the socket sleeve 1 is provided with a mating part that abuts against the guardrail 2-2 to prevent the protective sheet 2 from deforming.
[0026] Specifically, two guardrails 2-2 are provided on each side of the protective plate 2, with the guardrails 2-2 located near the end of the protective plate 2. The outer side of the socket sleeve 1 has a right-angle mating part, that is, a straight wall perpendicular to the outer side of the socket sleeve 1 is provided near the end of the outer side of the socket sleeve 1, with the straight wall facing the other end of the socket sleeve 1. A right-angle mating part is formed between the straight wall and the outer side of the socket sleeve 1. The inner side of the guardrail 2-2 and the side of the guardrail 2-2 near the end of the protective plate 2 respectively abut against the two sides of the right-angle mating part. The abutment of the guardrails 2-2 on both sides against the right-angle mating parts on both sides is used to prevent the protective plate 2 from deforming after long-term use.
[0027] In addition, the lower side of the protective plate 2 has a limiting surface 2-3 that mates with the top of the socket sleeve 1.
[0028] Example 5 differs from Example 3 in that, as Figure 2 As shown, the outer side of the socket sleeve 1 is provided with a hook B1-2. (As indicated...) Figure 4 As shown, the lower inner side of the insert sheath 3 is provided with a hanging point B3-1 that mates with the nose clip B1-2.
[0029] Specifically, the outer middle of the socket sleeve 1 is provided with two downwardly extending cantilever arms 1-6, and a hook B1-2 is provided between the two cantilever arms 1-6. When the pin sleeve is fitted on the outer side of the socket sleeve 1, the hook point B3-1 and the hook B1-2 are engaged to connect the socket sleeve 1 and the pin sleeve 3.
[0030] Furthermore, the lower ends of the two cantilever arms 1-6 are connected to pressing arms 1-4, such as... Figure 2 As shown. By pressing the press arms 1-4, as... Figure 6 As shown, this allows the extended cantilever 1-6 to fit more closely to the outside of the socket sleeve 1, disengaging the hook B1-2 from the hook point B3-1. This serves to unlock the socket sleeve 1 from the pin sleeve 3.
[0031] Example 6 differs from Example 5 in that, as Figure 4 As shown, the pin sleeve 3 is provided with two vertical anti-misalignment ribs B3-2. The two anti-misalignment ribs B3-2 and the hanging point B3-1 form two anti-misalignment gaps. The two anti-misalignment gaps fit with the two cantilever arms 1-6. That is, when the socket sleeve 1 and the pin sleeve 3 are connected, the cantilever arms 1-6 are inserted into the anti-misalignment gaps to play an anti-misalignment role.
[0032] In addition, the outer side of the socket sleeve 1 is provided with an anti-misalignment rib A1-3. In this embodiment, an anti-misalignment rib A1-3 is provided on the outer side of each of the two cantilever arms 1-6. When the socket sleeve 1 is connected to the pin sleeve 3, the anti-misalignment rib A1-3 fits against the outer side of the anti-misalignment rib B3-2, and works with the anti-misalignment rib B3-2 to play an anti-misalignment role.
[0033] Example 7 differs from Example 2 in that, as Figure 7 As shown, a TPA1-8 is inserted into the socket sleeve 1. TPA stands for Terminal Secondary Locking Structure. There is an opening on the side of the socket sleeve 1 for the TPA1-8 to be inserted, and the inner end of the TPA1-8 abuts against the terminal box inside the socket sleeve 1.
[0034] Furthermore, each end of the portion of the socket sleeve 1 that mates with TPA1-8 has a protrusion. Each end of TPA1-8 has two hook points C1-81 that can engage with the corresponding protrusions sequentially. The hook point C1-81 closer to the inner end of TPA1-8, i.e., the inward-facing end, is in the pre-installed position when it hooks with the protrusion. The hook point C1-81 closer to the outer end is in the fixed position when it hooks with the protrusion; that is, after pushing the pre-installed TPA1-8 inward, the hook point C1-81 closer to the outer end engages with the protrusion.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features therein, within the spirit and principles of the present utility model, shall not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model, and shall all be included within the protection scope of the present utility model.
