Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a large-current European-style connector plug. Background Art

[0002] Due to good visual effects, better eye-catching ability and publicity effect, large outdoor LED screens are becoming more and more popular among advertisers, and more and more large outdoor LED screens are being put into use. These outdoor LED screens are generally composed of multiple small LED screens. In order to ensure the display effect, how to reliably connect the small LED screens that make up the large LED screen is an important issue. Existing screens are generally connected through European connectors;

[0003] The existing connector mainly includes a plug and a socket. In actual use, since the pin extends out of the plug for a long time, the pin is easily bent under the action of external force.

[0004] After searching, the application number of the Chinese patent document is CN201920414912.1. The utility model relates to a European connector plug, which is used in the field of connector equipment. The key points of its technical solution are: it includes a plug shell, a card slot is opened on the plug shell, and a plurality of rows of pins are connected to the bottom of the card slot. Each row of pins is arranged along the length direction of the plug shell, and one end of the pin extends out of the plug shell in a direction away from the slot opening. A reinforcement block for the pin to pass through extends from the bottom of the card slot. Its advantage is: it reduces the risk of the pin being easily bent under the action of external force.

[0005] However, when the existing connector plug is connected to the LED display screen, the connector plug may become loose after long-term use, causing the connection signal to weaken or even disconnect. If the existing connector plug is used outdoors, the connection between the connector plug and the LED display screen may become loose, resulting in a gap. This may cause rainwater and other substances to enter the connection between the connector plug and the LED display screen, thereby damaging components such as connecting pins. Therefore, we need to propose a high-current European connector plug to solve the above problems. Utility Model Content

[0022] The connection fixing assembly 300 includes two sets of fixing blocks 301, which are integrally formed on the side ends of the connector plug body 100, and the fixing blocks 301 are embedded with connecting screw sleeves 302, and the two sets of connecting screw sleeves 302 are threadedly connected with connecting screws 303, and the connecting screws 303 are integrally formed with a hand-tightening cylinder 304 on one end away from the connecting pin 420;

[0023] When in use, the connector plug body 100 is inserted into the interface of the connecting device, and then the hand-tightening cylinder 304 is twisted to make the connecting screw 303 threadedly engage and move with the two sets of connecting screw sleeves 302, so that the connecting screw 303 extends forward and is finally threadedly connected to the thread groove at the interface of the connecting device, thereby fixing the connector plug body 100 on the interface of the connecting device to prevent it from falling off due to a gap between it and the interface of the connecting device due to external force or the like during long-term use.

[0024] An embedding groove 130 is provided at the front end of the connector plug body 100, and four sets of fixing screw sleeves 140 are embedded on the inner wall of the embedding groove 130. A rubber sealing ring 110 is fitted and fixed to the front end of the connector plug body 100. When the connector plug body 100 is fixed on the interface of the connecting device, the rubber sealing ring 110 is clamped between the connector plug body 100 and the connecting device, thereby filling the gap between the connector plug body 100 and the interface of the connecting device, preventing rainwater and other substances from falling between the connector plug body 100 and the interface of the connecting device.

[0025] The contact protection assembly 200 includes a contact protection seat 201, which is fitted and fixed in the embedding groove 130. A needle protection sleeve 202 is embedded in the contact protection seat 201. The end of the connecting pin 420 away from the connector plug body 100 passes through the needle protection sleeve 202 and extends to the outside of the needle protection sleeve 202. The needle protection sleeve 202 can guide the connecting pin 420 while protecting the base of the connecting pin 420 from bending.

[0026] Four groups of countersunk holes 203 are provided on the contact protection seat 201, and countersunk screw sleeves 204 are embedded in the countersunk holes 203. The countersunk screw sleeves 204 are integrally formed of a countersunk tube and an internal threaded cylinder. The inner diameter of the countersunk tube is larger than the inner diameter of the internal threaded cylinder. The four groups of countersunk screw sleeves 204 are respectively fixed to the four groups of fixed screw sleeves 140 by four cross screws 205, so that the contact protection seat 201 can be connected to the connector plug body 100 through the countersunk screw sleeves 204 and the fixed screw sleeves 140 using the cross screws 205.

[0027] The connecting pin 420 is electrically connected to the connecting data line 400, one end of the connecting data line 400 extends out of the rear end of the connector plug body 100, and an anti-bending sheath 410 is provided on the connecting data line 400;

[0028] The anti-bending sheath 410 is located on one end of the connecting data cable 400 close to the connector plug body 100 to prevent excessive bending of the connecting portion between the connecting data cable 400 and the connector plug body 100. Anti-slip grooves 120 are provided on the upper and lower ends of the connector plug body 100 to facilitate the operator to pinch the anti-slip grooves 120 of the connector plug body 100, thereby increasing the friction between the operator and the connector plug body 100, so that the connector plug body 100 can be easily inserted into the connection device interface.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
