Technical Field
[0001] This application relates to the field of waterproof packaging technology for proximity sensors, and more particularly to a waterproof proximity sensor housing. Background Technology
[0002] Proximity sensors are a general term for sensors that replace contact detection methods such as limit switches, aiming to detect objects without contact. They can detect the movement and presence of objects and convert it into electrical signals. Among the detection methods that convert into electrical signals, there are methods that utilize eddy currents generated in the metal body of the object due to electromagnetic induction, methods that utilize changes in the capacitance of electrical signals caused by the proximity of the object, and methods that use levers and guide switches.
[0003] As a core detection component in industrial automation, proximity sensors directly affect the operational stability of equipment. The market demand for waterproof sensors continues to grow, especially in harsh environments such as food processing, outdoor equipment, and chemical industries. Traditional split-wire connection methods are prone to internal circuit moisture short circuits due to sealing failure.
[0004] Therefore, this application proposes a waterproof proximity sensor housing. Utility Model Content
[0005] This application proposes a waterproof proximity sensor housing to address the problems mentioned in the background art. By incorporating a lead assembly, which is formed into a seamless integrated structure with the end of the housing through a co-extrusion molding process, the seamless integrated structure is installed at the end of the housing. This seamless integrated structure consists of an interface section, a wire section, and a bending section, which can prevent external water from entering the housing, effectively providing waterproofing. This prevents water from entering the housing through the threads and causing short circuits in the components, affecting normal use, and improving the service life of the proximity sensor. It also solves the problem of waterproofing failure caused by interface separation at the lead connection of traditional proximity sensors, greatly enhancing the practicality of the device.
[0006] To achieve the above objectives, this application adopts the following technical solution: A waterproof proximity sensor housing includes a housing assembly and a lead assembly. The housing assembly includes a shell and a front optical window. The lead assembly is formed into a seamless integrated structure with the end of the shell through a co-extrusion molding process. The seamless integrated structure consists of an interface segment, a wire segment, and a bending segment, and is wrapped around the outside of the wire.
[0007] In a preferred embodiment, a curved section is provided inside the housing and between the interface section and the line section, the curved section being an integral sleeve formed by multiple V-shapes; By setting up a lead wire assembly, which is formed into a seamless integrated structure with the end of the housing through a co-extrusion molding process, and installing the seamless integrated structure at the end of the housing, the seamless integrated structure consists of an interface section, a wire section, and a bending section. It can prevent external water from entering the housing, effectively playing a waterproof role, so as to prevent water from entering the housing through the threads and causing short circuits in the components, affecting normal use, improving the service life of the proximity sensor, and thus improving the practicality of the device.
[0008] In a preferred embodiment, a fastening structure is provided inside the housing and at the interface section, the fastening structure including a locking strip, a connecting strip, and a pressing strip; By setting up a fastening structure, a double compression effect can be achieved, further preventing water from entering and enhancing the waterproof effect, thereby improving the practicality of the device.
[0009] In a preferred embodiment, there are two locking strips, which are respectively disposed at both ends of the interface segment; The device's usability is enhanced by incorporating a fastening structure, including a locking strip, a connecting strip, and a clamping strip, with one locking strip located at the opening of the interface section and the other at the end of the housing.
[0010] In a preferred embodiment, the interface segment is provided with a plurality of connecting strips in the middle, and both ends of each connecting strip are connected to locking strips; By setting multiple connecting strips between the two locking strips, the tightness of the interface section is increased, ensuring the tightness between the interface section and the end of the housing, thereby improving the practicality of the device.
[0011] In a preferred embodiment, a clamping strip is provided between each of the connecting strips, and each clamping strip is located outside the interface segment; By setting a clamping strip between each connecting strip, with the clamping strip located between two locking strips, not only is the stability of the connecting strip enhanced, but the entry of seeping water is further prevented, improving waterproofness and thus enhancing the practicality of the device.
[0012] In a preferred embodiment, the interface segment has a slot inside, and the end of the outer shell is engaged in the slot; By creating a slot within the interface section, the end of the housing is snapped into the slot, making it difficult for moisture to enter the housing. This solves the problem of waterproofing failure caused by interface separation at the connection point of traditional proximity sensor leads, thereby improving the practicality of the device.
[0013] The beneficial effects of this application are: 1. This waterproof proximity sensor housing incorporates a lead wire assembly. The lead wire assembly is co-extruded to form a seamless integrated structure with the end of the housing. The seamless integrated structure, consisting of an interface section, a wire section, and a bending section, is installed at the end of the housing. This seamless integrated structure effectively prevents external water from entering the housing, thus providing waterproofing. It prevents water from entering the housing through the threads and causing short circuits in the components, affecting normal use, and improving the lifespan of the proximity sensor. This solves the problem of waterproofing failure caused by interface separation at the lead wire connection of traditional proximity sensors, greatly enhancing the practicality of the device. 2. This waterproof proximity sensor housing features a fastening structure including locking strips, connecting strips, and clamping strips. One locking strip is located at the opening of the interface section, and the other is located at the end of the housing, providing a double clamping effect to further prevent water from entering and enhance the waterproof effect. Multiple connecting strips are placed between the two locking strips to increase the tightness of the interface section and ensure the tightness between the interface section and the end of the housing. A clamping strip is placed between each connecting strip, with the clamping strip located between the two locking strips. This not only enhances the stability of the connecting strips but also further prevents infiltrated water from entering, improving waterproofness. A slot is provided in the interface section, and the end of the housing is engaged in the slot, making it difficult for water to enter the housing, greatly improving the practicality of the device.

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0017] Reference Figure 1-4 A waterproof proximity sensor housing includes a housing assembly 1 and a lead wire assembly 2. The housing assembly 1 includes a shell 11 and a front optical window 12. The lead wire assembly 2 is formed with the end of the shell 11 through a co-extrusion molding process to form a seamless integrated structure 21. The seamless integrated structure 21 is composed of an interface section 211, a wire section 212 and a bending section 213, and is wrapped around the outside of the wire.
[0018] Reference Figure 1-4 Inside the housing 11, between the interface section 211 and the wire section 212, there is a bent section 213. The bent section 213 is an integral sleeve formed by multiple V-shaped elements. By setting the lead wire assembly 2, the lead wire assembly 2 is formed with the end of the housing 11 through a co-extrusion molding process to form a seamless integrated structure 21. The seamless integrated structure 21 is installed at the end of the housing 11. The seamless integrated structure 21 is composed of the interface section 211, the wire section 212 and the bent section 213. It can prevent external water from entering the interior of the housing 11, effectively playing a waterproof role, so that water can enter the interior of the housing 11 through the threads and cause short circuits in the components, affecting normal use, improving the service life of the proximity sensor, and thus improving the practicality of the device.
[0019] Reference Figure 1-4 The outer casing 11 has a fastening structure inside the interface section 211. The fastening structure includes a locking strip 214, a connecting strip 215, and a pressing strip 216. By setting the fastening structure, a double pressing effect can be achieved, further preventing water from entering and enhancing the waterproof effect, thereby improving the practicality of the device.
[0020] Reference Figure 1-4 There are two locking bars 214, which are respectively set at both ends of the interface section 211. By setting a fastening structure, including locking bars 214, connecting bars 215 and pressing bars 216, one locking bar 214 is located at the opening of the interface section 211 and the other locking bar 214 is located at the end of the housing 11, thereby improving the practicality of the device.
[0021] Reference Figure 1-4 Multiple connecting strips 215 are provided in the middle of the interface section 211, and both ends of each connecting strip 215 are connected to the locking strip 214. By providing multiple connecting strips 215 between two locking strips 214, the tightness of the interface section 211 is improved, ensuring the tightness between the interface section 211 and the end of the housing 11, thereby improving the practicality of the device.
[0022] Reference Figure 1-4A clamping strip 216 is provided between each connecting strip 215, and each clamping strip 216 is located outside the interface section 211. By providing a clamping strip 216 between each connecting strip 215, and with the clamping strip 216 located between two locking strips 214, not only is the stability of the connecting strip 215 enhanced, but also the infiltration of water is further prevented, thus improving the waterproofness and enhancing the practicality of the device.
[0023] Reference Figure 1-4 The interface section 211 has a slot 217 inside, and the end of the housing 11 is engaged in the slot 217. By opening the slot 217 inside the interface section 211 and engaging the end of the housing 11 in the slot 217, moisture is not easily allowed to enter the housing 11, thus solving the problem of waterproof failure caused by interface separation at the connection of the traditional proximity sensor leads, thereby improving the practicality of the device.
[0024] Working principle: By setting the lead wire assembly 2, the lead wire assembly 2 is formed into a seamless integrated structure 21 with the end of the housing 11 through a co-extrusion molding process. The seamless integrated structure 21 is installed at the end of the housing 11. The seamless integrated structure 21 consists of an interface section 211, a wire section 212, and a bending section 213. It can prevent external water from entering the interior of the housing 11, effectively playing a waterproof role, so as to prevent water from entering the interior of the housing 11 through the threads and causing short circuits in the components, affecting normal use, and improving the service life of the proximity sensor. By setting a fastening structure, including a locking strip 214, a connecting strip 215, and a pressing strip 216, one locking strip 214 is located at the opening of the interface section 211, and the other locking strip 214 is located at the end of the housing 11. The interface section 211 has a double clamping effect, further preventing water from entering and enhancing the waterproof effect. Multiple connecting strips 215 are set between the two locking strips 214 to increase the tightness of the interface section 211 and ensure the tightness between the interface section 211 and the end of the housing 11. A clamping strip 216 is set between each connecting strip 215, and the clamping strip 216 is located between the two locking strips 214. This not only enhances the stability of the connecting strip 215, but also further prevents the infiltrated water from entering and improves the waterproof performance. A slot 217 is opened in the interface section 211, and the end of the housing 11 is engaged in the slot 217, making it difficult for water to enter the housing 11. This solves the problem of waterproof failure caused by interface separation at the connection of the traditional proximity sensor lead wire.
