Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to an inner rubber core structure of a connector. Background Art

[0002] A connector is a component or part used to connect or disconnect an electrical circuit, and can be connected or cut off without special tools and procedures such as welding, and can be achieved by hand or simple tools.

[0003] In traditional connectors, multiple pins are arranged on the same layer, and due to size problems, the arrangement diameter will be relatively large, making it difficult to miniaturize the diameter of the connector. Today, as electronic devices increasingly pursue miniaturization and thinness, a large connector diameter will occupy more space, which may further limit the layout and design of other components of the device, and even may affect the overall size and portability of the device, thus affecting the competitive advantage in the market.

[0004] Therefore, to solve the above problems, an inner rubber core structure of a connector is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an inner rubber core structure of a connector, which has the advantages of staggered connection between pins and the inner rubber core to reduce the diameter of the connector, and solves the problem that the large diameter of traditional connectors affects the overall size and portability of the device.

[0006] To achieve the above object, the utility model provides the following technical solution: An inner rubber core structure of a connector includes an inner rubber core body, and four lower-layer pins are vertically and spacedly inserted into the inner rubber core body. Adjacent two of the lower-layer pins are perpendicular to each other in the horizontal direction, and the four lower-layer pins are arranged in a surrounding manner with the center of the upper surface of the inner rubber core body as the center;

[0007] An upper-layer pin is vertically inserted into the inner rubber core body, and the upper-layer pin is arranged at the center of the four lower-layer pins;

[0008] The upper-layer pin and the lower-layer pin are vertically staggered, and the upper-layer pin is higher than the lower-layer pin in the vertical direction.

[0009] Further, four first slots are vertically opened downward on the upper surface of the inner rubber core body, and the four first slots are arranged in a surrounding manner with the center of the upper surface of the inner rubber core body as the center.

[0010] Further, the four first slots respectively correspond to the four lower-layer pins, and the four lower-layer pins are respectively inserted into the four first slots, and the lower-layer pins are inserted into the inner rubber core body through the first slots.

[0011] Further, internal threaded holes are formed in the outer walls of one sides of the four lower-layer pins, and bolts are threadedly connected in the internal threaded holes.

[0012] Further, four positioning holes are spaced apart on the outer side wall of the inner rubber core body and extend inwards to the four first slots respectively. The four positioning holes correspond to the four bolts respectively, and the heads of the bolts are located in the positioning holes.

[0013] Further, a second slot is formed downward at the center of the upper surface of the inner rubber core body and is located in the middle of the four first slots. The upper-layer pin is inserted into the second slot, and the upper-layer pin is inserted into the inner rubber core body through the second slot.

[0014] Further, four anti-rotation bosses are installed at intervals around the upper edge of the second slot. The upper-layer pin includes an anti-rotation block at the upper end, and the anti-rotation block is clamped between the four anti-rotation bosses.

[0015] Further, a sealing groove is formed on the outer side wall of the inner rubber core body, and a sealing ring is sleeved on the outer side wall of the sealing groove.

[0016] Further, a plurality of anti-rotation grooves are formed in a vertical direction around the outer periphery of the upper surface edge of the inner rubber core body.

[0017] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0018] For the inner rubber core structure of this connector, by using the first slot and the second slot to be vertically staggered along the inner rubber core body, the lower-layer pins and the upper-layer pins can be alternately inserted into the inner rubber core body vertically. Through the vertical alternating insertion method, the upper-layer pins and the lower-layer pins can be arranged more compactly in three-dimensional space, thereby effectively reducing the overall diameter of the connector and making the connector more suitable for use in application scenarios with limited space.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , in a connector inner rubber core structure in this embodiment, the first slot 11 and the second slot 12 are vertically staggered along the inner rubber core body 1, so that the lower layer pin 2 and the upper layer pin 3 can be alternately inserted into the inner rubber core body 1 vertically. In this way of vertical alternate insertion, the upper layer pin 3 and the lower layer pin 2 can be arranged more compactly in three-dimensional space, thereby effectively reducing the overall diameter of the connector and making the connector more suitable for use in application scenarios with limited space.

[0026] Specifically, a connector inner rubber core structure in this embodiment includes an inner rubber core body 1. Four lower layer pins 2 are vertically and spacedly inserted into the inner rubber core body 1, and two adjacent lower layer pins 2 are perpendicular to each other in the horizontal direction. The four lower layer pins 2 are arranged in a surrounding manner with the center of the upper surface of the inner rubber core body 1 as the center;

[0027] An upper layer pin 3 is vertically inserted into the inner rubber core body 1, and the upper layer pin 3 is arranged at the center of the four lower layer pins 2;

[0028] The upper layer pin 3 and the lower layer pin 2 are vertically staggered, and the upper layer pin 3 is higher than the lower layer pin 2 vertically.

[0029] In the actual use process, through the way of vertical alternate insertion, the upper layer pin 3 and the lower layer pin 2 can be arranged more compactly in three-dimensional space, thereby effectively reducing the overall diameter of the connector and making the connector more suitable for use in application scenarios with limited space.

[0030] Four first slots 11 are vertically opened downward along the upper surface of the inner rubber core body 1, and the four first slots 11 are arranged in a surrounding manner with the center of the upper surface of the inner rubber core body 1 as the center.

[0031] The four first slots 11 respectively correspond to the four lower pins 2, the four lower pins 2 are respectively inserted into the four first slots 11, and the lower pins 2 are inserted into the inner rubber core body 1 through the first slots 11.

[0032] Internal threaded holes 21 are provided on the outer side walls of one side of the four lower pins 2, and bolts 22 are connected to the internal threaded holes 21 by internal threads.

[0033] Four positioning holes 13 are spaced apart on the outer side wall of the inner rubber core body 1 and extend inward to the four first slots 11 respectively. The four positioning holes 13 respectively correspond to the four bolts 22, and the heads of the bolts 22 are located in the positioning holes 13.

[0034] During actual use, the user inserts four pins into the first slots 11, and then installs the bolts 22 into the internal threaded holes 21 through the positioning holes 13. The lower pins 2 can be inserted into the inner rubber core body 1 through the first slots 11 by manual loading, eliminating the process of pressing in by a press and improving the assembly efficiency. At the same time, under the limitation of the positioning holes 13 and the bolts 22, the lower pins 2 can be effectively prevented from moving vertically.

[0035] A second slot 12 is provided downward at the center of the upper surface of the inner rubber core body 1 and is located among the four first slots 11. The upper pin 3 is inserted into the second slot 12, and the upper pin 3 is inserted into the inner rubber core body 1 through the second slot 12.

[0036] Four anti-rotation bosses 14 are installed around the upper edge of the second slot 12 at intervals. The upper pin 3 includes an anti-rotation block 31 at the upper end, and the anti-rotation block 31 is clamped between the four anti-rotation bosses 14.

[0037] Under the cooperation of the anti-rotation block 31 and the anti-rotation bosses 14, the upper pin 3 is prevented from rotating when inserted into the inner rubber core body 1.

[0038] A sealing groove is provided on the outer side wall of the inner rubber core body 1, and a sealing ring 15 is sleeved on the outer side wall of the sealing groove.

[0039] Through the sealing ring 15, the inner rubber core structure can be sealed after being connected to the outer shell, preventing the connector from failing due to water ingress.

[0040] A plurality of anti-rotation grooves 16 are provided vertically around the outer periphery of the inner rubber core body 1 at the edge of the upper surface of the inner rubber core body 1.

[0041] By matching the anti-rotation grooves 16 with the anti-rotation bosses 14 on the outer shell, when the inner rubber core structure is connected to the outer shell, the connector outer shell can be effectively prevented from loosening due to factors such as equipment vibration, avoiding the situation of poor sealing of the connector caused by the loosening of the outer shell.

[0042] The working principle of the above embodiment is as follows:

[0043] During actual use, the user inserts four pins into the first slot 11, and then installs the bolt 22 into the internal thread hole 21 through the positioning hole 13. Under the limitation of the positioning hole 13 and the bolt 22, the lower pins 2 can be effectively prevented from moving vertically. Then the user inserts the upper pins 3 into the second slot 12 and engages the anti-rotation block 31 between the four anti-rotation bosses 14. Under the restriction of the anti-rotation block 31 and the anti-rotation bosses 14, the upper pins 3 can be prevented from rotating when inserted into the inner rubber core body 1.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
