Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile fault diagnosis, especially to a automobile fault diagnosis adapter with high-strength structure and anti-misplug characteristics. BACKGROUND

[0002] The OBD diagnosis adapter is a hardware adapter matched with an automobile fault diagnosis instrument to diagnose a vehicle to be repaired. One end of the adapter is connected to a diagnosis main line, and the other end of the diagnosis main line is connected to a diagnosis instrument. Then, the adapter is inserted into an OBD16 diagnosis female seat to establish communication between the diagnosis instrument and the vehicle, so that the vehicle can perform signal interaction, fault detection, programming, and other operations.

[0003] The existing OBD16 male plug is made of soft rubber, which is easy to deform and difficult to plug into the vehicle. In some use scenarios, when an HDB15 connector is needed, the connection between the OBD16 adapter and the main line is only dependent on the connection stiffness of the HDB15 connector itself, which may cause the core connection part to collapse in extreme conditions. The HDB15 male end is only partially protected by soft rubber, and accidental dropping may cause the tin-plated iron to deform and be unable to connect.

[0004] In addition, the HDB15 male port is flush with the soft plastic protection, and the anti-misplug effect is not good. When the operator reverses the plug, the HDB15 anode contactor is still easy to bend and deform, causing the signal needle inside the HDB15 connector to be offset or deformed, and the signal cannot be connected and used, resulting in misdiagnosis of the diagnosis instrument or damage to the vehicle and the vehicle diagnosis instrument.

[0005] Therefore, the present technical solution provides an automobile fault diagnosis adapter with high-strength structure and anti-misplug characteristics, which has an integrated plastic shell with high-strength structure, anti-misplug, and foolproof features, and a long service life. SUMMARY

[0031] The working principle is as follows:

[0032] The OBD male plug, the HDB male plug 12 and the connecting main head 13 are integrated by one-piece injection molding after the OBD male plug and the HDB male plug 12 are welded according to the process joint mode. The outer shape structure is as follows: one end is the OBD male plug, mainly connected with the output interface of the automobile; one end is the HDB male plug 12 connected with the diagnostic wire harness; and the middle part is the engineering plastic PVC full-surrounding structure, which can be used in various extreme environments to achieve oil-proof, rain-proof, shock-proof and drop-resistant. The product is small in size, simple in operation, convenient to use, and good in error-proof and fool-proof performance.

[0033] The OBD male plug is made of engineering plastic to solve the cracking problem caused by over-tight plugging in extreme environments. The original inner skeleton and PVC soft rubber structure are replaced by engineering plastic. The one-piece injection molded OBD male plug structure (PC+ABS) is mainly composed of a protective shell 100, a stainless steel clamping spring piece 103 and a plurality of anode metal contactors 102. The plastic main body is in a "day" shape half-surrounding structure from the front. The metal contactors 102 are first placed in the plastic injection mold through a jig, and then the engineering plastic (PC plastic) is injected into the mold by an injection molding machine, tightly wrapping the specific positions of the anode metal contactors 102. After the plastic cools and solidifies, the protective shell 100 and the butt joint guide opening tongue piece 101 (butt joint guide) are formed. The bottom has a 7.8mm wide and 13.3mm long pre-slot and a 7.8mm wide and 0.7mm pre-hole for assembling the stainless steel clamping spring piece 103. A groove is designed at the tail for molding with the dissolved engineering plastic (PVC), realizing product fastening and stability.

[0034] The stainless steel clamping spring piece 103 is a key component of the OBD male plug, and its structure design and material selection are crucial. The clamping spring piece 103 is formed by stainless steel SUS304 stamping process. The stainless steel material has effective corrosion resistance to prevent surface oxidation, and the toughness and strength of stainless steel can perfectly lock and plug the convex buckle on the female seat for more than 10,000 times without deformation, ensuring the stability and durability of long-term use. The opening of the clamping spring piece 103 and the middle part are outwardly open. The opening position is outwardly open, which plays a guiding role when contacting with the female seat. The middle part is outwardly concave, which perfectly matches the convex buckle on the female seat after the female seat is assembled. The structure is a wave-shaped structure to increase the range of elastic deformation and restoring force of the clamping spring piece 103, ensuring good contact pressure.

[0035] The HDB male plug 12 adopts the common HDB male plug 12 structure on the market.

[0036] The external structure of the HDB male plug 12 is formed by a plastic main body, which is integrally formed by injection molding, and an opening shape is designed on one side of the rectangular structure, which is the key to realize the fool-proof function, and solves the problem that the terminal operator can easily identify the positive and negative interfaces when connecting, and avoids the problem of interface damage caused by operation errors.

[0037] In a preferred embodiment of the utility model, the horse mouth slot 124 is provided with a fixing hole 122 on both sides, and the connecting main head 13 is provided with a through hole 132 corresponding to the fixing hole 122.

[0038] The strong fixation can be further realized, and the through hole 132 is matched with the fixing hole 122, and the combination of screws and the like is strengthened.

[0039] In a preferred embodiment of the utility model, the horse mouth slot 124 is provided with a fixing hole 122 on both sides, and the connecting main head 13 is provided with a through hole 132 corresponding to the fixing hole 122.

[0040] The space avoiding position 125 can prevent the deformation of the horse mouth slot 124 caused by the internal shrinkage and extrusion of the gel after solidification.

[0041] In a preferred embodiment of the utility model, the horse mouth slot 124 is provided with a fixing hole 122 on both sides, and the connecting main head 13 is provided with a through hole 132 corresponding to the fixing hole 122.

[0042] In a preferred embodiment of the utility model, the horse mouth slot 124 is provided with a fixing hole 122 on both sides, and the connecting main head 13 is provided with a through hole 132 corresponding to the fixing hole 122.

[0043] The opening and the middle part of the clamping spring sheet 103 are outwardly opened, the opening position is outwardly opened, the middle part is outwardly recessed, and the opening position is outwardly opened, which has a guiding effect when contacting the female seat.

[0044] In a preferred embodiment of the utility model, the horse mouth slot 124 is provided with a fixing hole 122 on both sides, and the connecting main head 13 is provided with a through hole 132 corresponding to the fixing hole 122.

[0045] When the male port part is flush with the soft plastic protective shell 100, the fool-proof effect is not good, and when the operator reversely inserts, the terminal 121 anode contactor 102 is still easy to be bent and deformed. Therefore, the recess design structure can avoid the problem.

[0046] The above-mentioned is only a preferred embodiment of the technical scheme of the utility model, and does not limit the patent range of the technical scheme of the utility model, and any equivalent structural transformation or direct / indirect application in other related technical fields within the technical scheme of the utility model technical scheme is included in the patent protection range of the utility model technical scheme.
