Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, specifically a waterproof and dustproof sealed wire harness connector. Background Technology

[0002] With the widespread application and continuous development of electronic devices, the wiring harness connection between various electrical devices and within devices has become crucial. Whether it is automated equipment in industrial production or various electronic and electrical products in daily life, they all rely on wiring harness connectors to achieve stable power transmission and signal connection.

[0003] Electrical equipment used in outdoor environments, such as streetlights and surveillance cameras, are exposed to the natural environment for a long time and face harsh conditions such as rain and dust. Even in indoor environments, some special places such as kitchens and bathrooms may have factors such as moisture and oil that may affect the normal operation of wire harness connectors.

[0004] Traditional wire harness connectors are not sufficiently sealed to withstand these complex environments, failing to effectively prevent the intrusion of water and dust. Once water enters the connector, it can easily lead to short circuits and corrosion, affecting the stability of power transmission and even causing equipment failure. The accumulation of dust can also interfere with signal transmission and reduce the lifespan of the connector. Therefore, there is an urgent need to develop a waterproof and dustproof sealed wire harness connector to solve these practical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waterproof and dustproof sealed wire harness connector, which solves the problem that traditional wire harness connectors are not sealing enough in these complex environments and cannot effectively prevent the intrusion of water and dust. Once water enters the connector, it can easily lead to short circuits and corrosion.

[0006] To achieve the above objectives, this utility model provides a waterproof and dustproof sealed wire harness connector through the following technical solution: a male connector, a female connector inserted into one side of the male connector, a conductive base fixed to the bottom of the female connector, a conductive terminal corresponding to the conductive base inside the male connector, and wires for transmitting power passing through the inside of both the male and female connectors.

[0007] It also includes a waterproof and dustproof mechanism, which includes a first rubber ring disposed on the outside of the female connector, and the first rubber ring has a trapezoidal cross-section. The male connector is fitted with a second rubber ring corresponding to the first rubber ring, and the second rubber ring has a trapezoidal groove inside that is adapted to the first rubber ring. The female connector is also provided with a silicone ring on the outside of the end near the first rubber ring, and the male connector has a mating groove at one end that is used to cooperate with the silicone ring.

[0008] Preferably, stress relief sleeves are fitted on one side of both the male and female connectors, and the wires pass through the inside of the stress relief sleeves. Hollow grooves are equidistantly opened on the surface of the stress relief sleeves.

[0009] Preferably, a heat dissipation component is further provided on the outside of the male connector. The heat dissipation component includes a heat dissipation substrate disposed on the outside of the male connector, a graphite heat sink fixedly connected to the outside of the heat dissipation substrate, and a heat dissipation shell for heat dissipation fixedly connected to the outside of the graphite heat sink.

[0010] Preferably, multiple sets of heat-conducting grooves are equidistantly provided on the outer side of the heat dissipation shell to enhance the heat dissipation effect.

[0011] Preferably, the heat dissipation substrate is made of aluminum.

[0012] Preferably, two sets of fixing plates are also embedded and installed on the outer side of the heat dissipation substrate, and multiple sets of rubber strips are installed at equal intervals on the surface of the fixing plates.

[0013] This invention provides a waterproof and dustproof sealed wire harness connector. Compared with the prior art, it has the following advantages.

[0014] 1. When the male connector moves, it drives the first rubber ring on the outside of the female connector to move synchronously and insert into the second rubber ring on the outside of the male connector. The trapezoidal groove tightly contacts and seals with the first rubber ring. At the same time, the male connector drives the silicone ring to insert into the mating groove for sealing. The double-layer seal inside and outside achieves waterproof and dustproof connection of the wire harness, solving the problem of poor sealing of traditional connectors that allows water and dust to enter, affecting power transmission, causing short circuits, and damaging the wire harness and external equipment.

[0015] 2. The heat dissipation substrate is made of aluminum, which utilizes its excellent thermal conductivity to quickly conduct the heat generated during power transmission between the male and female connectors. Graphite heat sinks further absorb and diffuse this heat. The heat dissipation shell protects the internal heat dissipation structure and assists in heat dissipation. Multiple sets of heat conduction grooves increase its heat dissipation surface area, accelerate heat dissipation, achieve efficient heat dissipation, solve the problem of connector performance degradation and shortened lifespan due to heat generation, ensure that it operates at a stable temperature, and improve reliability and service life.

[0021] 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.

[0022] First implementation method:

[0023] refer to Figure 1-4 A waterproof and dustproof sealed wire harness connector includes a male connector 1, a female connector 101 inserted into one side of the male connector 1, a conductive base 2 fixed to the bottom of the female connector 101, a conductive terminal 201 corresponding to the conductive base 2 opened inside the male connector 1, and a wire 5 for transmitting power is installed through the male connector 1 and the female connector 101.

[0024] It also includes a waterproof and dustproof mechanism 3, which includes a first rubber ring 301 disposed on the outside of the female connector 101, and the first rubber ring 301 has a trapezoidal cross-section. A second rubber ring 302 corresponding to the first rubber ring 301 is sleeved on the outside of the male connector 1, and a trapezoidal groove 303 adapted to the first rubber ring 301 is opened inside the second rubber ring 302. A silicone ring 304 is also disposed on the outside of the female connector 101 near the first rubber ring 301, and a mating groove 305 that mates with the silicone ring 304 is opened at one end of the male connector 1.

[0025] Both the male connector 1 and the female connector 101 have stress relief sleeves 6 fitted on one side, and the wires 5 pass through the inside of the stress relief sleeves 6. Hollow grooves 601 are equidistantly opened on the surface of the stress relief sleeves 6.

[0026] When the male connector 1 is moved to the side of the female connector 101, the conductive base 2 is inserted into the male connector 1, and the conductive terminal 201 also enters the conductive base 2 accordingly, thereby enabling the wire 5 to be electrically connected to the conductive base 2 and the conductive terminal 201, thus completing the construction of the power transmission line.

[0027] During the movement of the male connector 1, the first rubber ring 301 on the outside of the female connector 101 moves synchronously. The first rubber ring 301 is inserted into the second rubber ring 302 on the outside of the male connector 1, and is tightly sealed to the first rubber ring 301 through the trapezoidal groove 303 inside the second rubber ring 302.

[0028] Since the first rubber ring 301 has a trapezoidal cross-section and is compatible with the trapezoidal groove 303, a good sealing fit is formed between the two, which can effectively prevent external water and dust from entering from the outer gap of the male connector 1 and the female connector 101.

[0029] Simultaneously, the movement of the male connector 1 also causes the silicone ring 304 of the female connector 101, which is close to the outer side of the first rubber ring 301, to insert into the mating groove 305 at one end of the male connector 1 for contact sealing. Through the sealing between the outer first rubber ring 301 and the second rubber ring 302, and the sealing between the inner silicone ring 304 and the mating groove 305, a double-layer sealing structure is formed. This double-layer sealing structure achieves waterproof and dustproof connection at the wire harness, effectively solving the problem of poor sealing of traditional wire harness connectors, which allows water and dust to enter and affect the stability of power transmission, as well as causing short circuits, resulting in abnormal power supply to the wire harness and external equipment, and damage to the wire harness and external equipment.

[0030] The hollow grooves 601 equidistantly opened on the surface of the stress relief sleeve 6 play the role of buffering and dispersing stress. When the device is subjected to external force pulling or vibration, the hollow grooves 601 can allow the stress relief sleeve 6 to undergo a certain deformation, thereby preventing the conductor 5 from being damaged due to stress concentration, providing protection for the conductor 5, and ensuring the reliability of power transmission.

[0031] Second implementation method:

[0032] When using connectors for power transmission, as the power of electrical equipment continues to increase, the connectors will generate a lot of heat during operation. If heat cannot be dissipated in time, the connector temperature will become too high, which will affect its performance and reliability and shorten the overall service life of the equipment. In order to address the above problems, this device is also designed with a heat dissipation component, specifically as follows:

[0033] refer to Figure 4 In the second embodiment of this utility model, a heat dissipation component 4 is also provided on the outside of the male connector 1. The heat dissipation component 4 includes a heat dissipation substrate 401 disposed on the outside of the male connector 1, a graphite heat dissipation sheet 402 fixedly connected to the outside of the heat dissipation substrate 401, and a heat dissipation shell 403 for heat dissipation fixedly connected to the outside of the graphite heat dissipation sheet 402.

[0034] Multiple sets of heat conduction grooves 404 are equidistantly provided on the outer side of the heat dissipation shell 403 to enhance the heat dissipation effect. The heat dissipation base plate 401 is made of aluminum. Two sets of fixing plates are also embedded on the outer side of the heat dissipation base plate 401. Multiple sets of rubber strips 7 are equidistantly installed on the surface of the fixing plates.

[0035] The heat dissipation substrate 401 is made of aluminum, which has good thermal conductivity and can quickly conduct heat generated during power transmission after the male connector 1 and female connector 101 are connected. The graphite heat sink 402 can further absorb and diffuse the heat conducted from the heat dissipation substrate 401. The heat dissipation shell 403 not only protects the internal heat dissipation structure, but also has a certain heat dissipation capacity. Multiple sets of heat conduction grooves 404 increase the heat dissipation surface area of ​​the heat dissipation shell 403, so that heat can be dissipated to the surrounding environment more efficiently.

[0036] Through the synergistic effect of the heat dissipation substrate 401, the graphite heat sink 402 and the heat dissipation shell 403, and the assistance of the heat conduction groove 404, a good heat dissipation function is achieved, which effectively solves the problems of performance degradation and shortened lifespan caused by heat generation during power transmission, ensuring that the connector works in a stable temperature environment and improving its reliability and service life.

[0037] Multiple rubber strips 7 are installed on the front of the fixed plate. The rubber material used in them increases the friction. When the operator needs to hold the male connector 1 and the female connector 101 to dock or separate them, the hand comes into contact with the rubber strips 7. This friction allows the operator to grip the connector more steadily and makes it easier to push it.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
