Description

Technical Field

[0001] This utility model relates to the technical field of connectors, specifically to a novel spark-proof cable connector. Background Technology

[0002] Connectors are commonly used to connect two active devices to transmit current and signals, and are widely used in various fields. The quality of the connector directly determines the reliability of current and signal transmission, making it essential to improve the structure of connectors.

[0003] Existing connectors consist of a connector head and a connector socket. The connector head has a built-in male connector pin, which connects to the cable. When the male connector pin and the female connector pin come into contact, current and signals can be transmitted. However, when existing cable connectors are used in applications with high current and high voltage, sparks can easily occur at the moment of contact between the male and female connector sockets due to accumulated resistance, posing a safety risk. To address the aforementioned issues, patent number 202222904415.4 discloses a spark-proof cable connector, including a male connector and a female connector that plugs into the male connector. The female connector includes a plug section, and the male connector includes an insertion section that can be plugged into the plug section. Both the male and female connectors contain cables that connect to the insertion section and plug section, respectively. The connector also includes a spark-proof structure, comprising a mounting shell, a surface mount resistor, and two stamped metal plates. The two stamped metal plates are respectively mounted on opposite sides of the mounting shell, and the surface mount resistor is mounted on the mounting shell with its two ends in contact with the two stamped metal plates. Through this spark-proof structure, the male connector first contacts the outermost stamped metal plate of the female connector. Current and voltage pass through the spark-proof structure before passing through the female connector, and the surface mount resistor effectively eliminates sparks during this process, resulting in a high level of connector safety. However, the connector still has the following problems: 1. It can only eliminate sparks, but it has poor sealing and waterproof performance, and cannot be used in humid environments, thus limiting its use environment; 2. The exposed parts of the existing connection cable are not reinforced or protected, which leads to the outer sheath cracking after long-term use, causing the internal wire core of the cable to be exposed, affecting the service life of the connector. Utility Model Content

[0004] This utility model addresses the shortcomings of current technology by providing a novel spark-proof cable connector, aiming to solve the technical problems of short service life and poor waterproof performance of existing connectors.

The plug-in section has a spark-proof structure and a sealing structure. Reinforced protection structures are provided between the male connector and the cable, and between the female connector and the cable.

[0007] As a further improvement, the male connector includes a housing 1, which has a mounting step hole 1 and a connecting groove. The insertion section is disposed in the mounting step hole 1, and the connecting groove is disposed at the end of the housing 1. The female connector includes a housing 2, which has a mounting step hole 2 and a connecting protrusion. The insertion section is disposed in the mounting step hole 2. The connecting groove and the connecting protrusion are engaged and connected.

[0008] As a further improvement, the connecting protrusion is provided with an annular groove and an annular groove one, the annular groove being disposed on the outer wall of the connecting protrusion and the annular groove one being disposed on the inner wall of the connecting protrusion.

[0009] As a further improvement, the spark-proof structure is disposed within the annular groove and on the outer side of the end of the plug section; the spark-proof structure includes a mounting shell and two stamped metal sheets, the mounting shell is disposed between the two stamped metal sheets, the mounting shell has multiple mounting slots, and each mounting slot is provided with a surface mount resistor; the stamped metal sheets are bonded to the surface mount resistors.

[0010] As a further improvement, the sealing structure includes a sealing ring disposed within the annular groove, the sealing ring being used to fit against the interior of the connecting groove during connection.

[0011] As a further improvement, the enhanced protection structure includes a mounting groove and a reinforcing sleeve. The mounting groove is located at the end of the outer shell 1 and the outer shell 2. The mounting groove 1 has multiple annular protrusions arranged in an array. One end of the reinforcing sleeve is located in the mounting groove 1, and the reinforcing sleeve is tightly attached to the outside of the cable by heat shrinking.

[0012] As a further improvement, both the outer casing 1 and the outer casing 2 are provided with two mirror-opposite protrusions.

[0013] Compared with the prior art, the above-mentioned technical solutions of the novel spark-proof cable connector provided by the present invention have at least one of the following technical effects:

[0014] 1. This utility model eliminates sparks and improves the safety of the new spark-proof cable connector by setting a spark-proof structure to prevent sparks; and improves the water resistance and environmental applicability of the new spark-proof cable connector by setting a sealing structure composed of sealing rings to improve the sealing performance of the connection between the male end connector and the female end connector.

[0015] 2. By setting up a reinforced protective structure consisting of an installation groove and a reinforcing sleeve, external moisture is prevented from flowing into the insertion section or plug-in section from the cable, thereby improving the sealing performance between the cable and the outer shell 1 and outer shell 2, and increasing the strength of the connection. This better protects the cable connected to the movable end of the outer shell 1 and outer shell 2, and improves the service life of the new type of spark-proof cable connector.

The connecting groove 22 and the connecting protrusion 32 cooperate to connect and position the connector, ensuring quick alignment between the insertion section 4 and the plug section 5, thereby ensuring connection stability and extending the service life of the new spark-proof cable connector.

[0024] The connecting protrusion 32 is provided with an annular groove 320 and an annular groove 321. The annular groove 320 is provided on the outer wall of the connecting protrusion 32, and the annular groove 321 is provided on the inner wall of the connecting protrusion 32. The anti-spark structure 7 is provided in the annular groove 321 and on the outer side of the end of the plug section 5.

The stamped metal sheets 71 are bonded to the surface mount resistors 72. The anti-spark structure 7 is used to prevent sparks, thereby eliminating the generation of sparks and improving the safety of the new anti-spark cable connector.

[0025] The sealing structure 8 includes a sealing ring disposed within the annular groove 320. The sealing ring is used to fit against the interior of the connecting groove 22 during connection.
