Description

Technical Field

[0001] The utility model relates to the technical field of electrical connectors, and more specifically, the utility model relates to a connection structure of an electrical connector. Background Art

[0002] Connectors are quite important components when mechanical or electronic products are interconnected. They are interconnected through connectors and connecting wires, so that signals or power can be transmitted between them.

[0003] Most of the connection structures of electrical connectors are made of plastic materials. To ensure firm connection, most plastic connection shells are provided with a buckle and a snap ring on the side to fixedly connect the two ends of the electrical connector. However, in many cases, the electrical connection is in a long-term connection state, and the buckle and the snap ring will be corroded by moisture and dust in the air for a long time, resulting in the adhesion of the buckle and the snap ring, making it difficult to separate them. This greatly increases the difficulty of disconnecting the connection. Moreover, in most cases, after disconnection, the buckle and the snap ring will be damaged, resulting in the lack of good cooperation between the buckle and the snap ring after secondary connection, and thus losing the good connection fastening effect. Therefore, it needs to be improved. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a connection structure of an electrical connector.

[0005] To achieve the above object, the utility model provides the following technical solution: A connection structure of an electrical connector includes a male end and a female end of the connector. The male end and the female end of the connector are inserted into each other, and a connection structure is arranged outside the male end and the female end of the connector.

[0006] The connection structure includes a protection component movably sleeved outside the female end of the connector. A positioning ring is fixedly sleeved outside the male end of the connector. A limit connection ring is fixedly sleeved at one end of the protection component close to the male end of the connector.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 5 shown, the present utility model provides an electrical connector connection structure, including a connecting sub-end 1 and a connector female end 2, the connecting sub-end 1 and the connector female end 2 are inserted into each other, and a connecting structure 3 is arranged outside the connecting sub-end 1 and the connector female end 2;

[0025] The connection structure 3 includes a protective component 31 that is movably sleeved outside the female connector end 2. A positioning ring 32 is fixedly sleeved outside the sub-end 1 of the connection. A limiting connection ring 33 is fixedly sleeved at one end of the protective component 31 close to the sub-end 1 of the connection. Two upper and lower card slots 34 are formed on one side of the outer surface of the positioning ring 32 close to the sub-end 1 of the connection. Two upper and lower blocks 35 are fixedly connected to one side of the outer surface of the limiting connection ring 33 close to the female connector end 2. The block 35 is movably clamped inside the card slot 34. Due to the setting of the positioning ring 32, the connection between the sub-end 1 and the female connector end 2 and the internal connection structure can be protected in cooperation with the protective sleeve 311, avoiding being eroded by water vapor and dust in the air during long-term connection, thereby slowing down the corrosion damage rate of the connection structure and reducing the difficulty of plugging and unplugging.

[0026] Among them, a guiding surface 36 is provided on one side of the outer surface of the positioning ring 32 close to the female connector end 2, and a guiding surface 36 is also provided on one side of the outer surface of the limiting connection ring 33 close to the sub-end 1 of the connection. The smooth inclined surfaces of the outer surfaces of the two guiding surfaces 36 are parallel to each other. Due to the setting of the two guiding surfaces 36, their cooperation can facilitate the movement of the protective sleeve 311, and further ensure that the block 35 can cross the positioning ring 32 and be clamped into the internal card slot 34 during plugging.

[0027] Among them, the front and rear sides of the positioning ring 32 are made of soft rubber, and the hardness of the upper and lower sides of the positioning ring 32 is greater than that of its front and rear sides. Due to the setting of the positioning ring 32 and the limiting connection ring 33, a good sealing effect can be achieved for the connection end and the connection structure of the internal sub-end 1 and the female connector end 2 in cooperation with the protective sleeve 311. At the same time, it is convenient for the user to pinch the front and rear sides of the protective sleeve 311, so that the upper and lower sides of the protective sleeve 311 can expand outwardly, so that the block 35 can cross the positioning ring 32 after disengaging from the card slot 34 to disconnect the connection between the sub-end 1 and the female connector end 2.

[0028] Among them, the inner diameter dimensions of the positioning ring 32 and the limiting connection ring 33 are adapted to the outer diameter dimensions of the sub-end 1 of the connection, and the outer diameter dimensions of the positioning ring 32 are adapted to the inner diameter dimensions of the protective component 31.

[0029] Among them, the protective component 31 includes a protective sleeve 311 that is movably sleeved outside the female connector end 2. Two front and rear limiting sliding grooves 312 are formed on both the upper and lower sides of the outer surface of the female connector end 2. A limiting sliding block 313 is slidably clamped inside the limiting sliding groove 312. The outer side of the limiting sliding block 313 penetrates the limiting sliding groove 312 and extends to the outside of the female connector end 2 and is fixedly connected to the inside of the protective sleeve 311.

[0030] Among them, a reset spring 314 is arranged inside the limit slider 313. One end of the reset spring 314 close to the female connector end 2 is connected to the limit slider 313, and the other end of the reset spring 314 is connected to the inner wall of the limit chute 312. Due to the arrangement of the reset spring 314, under the action of its elastic force, after the male connector end 1 and the female connector end 2 are connected and fixed, the protective sleeve 311 can move relatively and drive the limit connection ring 33 and the clamping block 35 to cross over the positioning ring 32. Then, under the restoring force of the reset spring 314, it is ensured that the clamping block 35 can automatically snap into the inside of the card slot 34, effectively preventing the disconnection of the male connector end 1 and the female connector end 2 caused by accidental pulling during the connection. Moreover, due to the elastic force of the reset spring 314, it can provide a buffering effect for accidental pulling and avoid the situation of breakage caused by strong pulling.

[0031] Among them, an input connection end 4 is fixedly connected to the outer end of the male connector end 1. The other end of the input connection end 4 is connected to an input cable 5. An output connection end 6 is fixedly connected to the outer end of the female connector end 2. The other end of the output connection end 6 is connected to an output cable 7.

[0032] Among them, a connection plug 8 is arranged inside the female connector end 2 on the side close to the male connector end 1. When the male connector end 1 is inserted into the female connector end 2, the connection plug 8 is simultaneously inserted into the inside of the male connector end 1.

[0033] The working principle and usage process of the present utility model:

[0034] After inserting the male connector end 1 and the female connector end 2 into each other, sliding the protective sleeve 311 towards the side of the male connector end 1 can drive the limit slider 313 to move under the restriction of the limit chute 312, thereby compressing the limit slider 313. Since the movement of the protective sleeve 311 can drive the limit connection ring 33 and the clamping block 35 to gradually approach the positioning ring 32, when the card slot 34 contacts the positioning ring 32, continuing to pull the protective sleeve 311 can deform the upper and lower sides of the protective sleeve 311 outwards with the cooperation of the guiding surface 36, and finally enable the clamping block 35 to cross over the positioning ring 32. After it completely crosses over the positioning ring 32, under the action of the deformation recovery of the protective sleeve 311, the clamping block 35 is reset to the side of the card slot 34. Then, releasing the protective sleeve 311 can enable the clamping block 35 to snap into the inside of the card slot 34 under the action of the elastic force recovery of the reset spring 314.

[0035] When disconnection is required, pinch the front and rear sides of the protective sleeve 311, and the middle parts of the wide surfaces on the upper and lower sides thereof will expand outwards, causing the upper and lower two clamping blocks 35 to move away from each other and away from the connecting sub-end 1. Until the distance between the two clamping blocks 35 is greater than the distance between the upper and lower sides of the positioning ring 32, continue to pull the protective sleeve 311 towards the connector female end 2, and the clamping block 35 can cross over the positioning ring 32 to release the connection between the protection component 31 and the positioning ring 32. Furthermore, the connection plug 8 can be pulled out from the connecting sub-end 1.
