Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a waterproof connector. Background Art

[0002] Connectors are widely used in a variety of electronic products. With the trend toward lighter and more miniaturized electronic products, the requirements for product structure are increasing, requiring them to be stable and easy to assemble and process. Conventional connectors have plastic or steel windows above and below the exposed tongue, which takes up space. LIM (waterproof adhesive) increases the thickness of the connector panel by interfering with the outer ribs and squeezing them. LIM molding on the outer plastic layer results in excessive overall connector thickness, and the LIM molding process can easily damage internal terminal components.

[0003] The thickness of the exposed part of the tongue of the existing waterproof connector is too thick, which seriously occupies the space of the mechanism panel; the silicone ring is directly LIM-molded on the tongue window, and the silicone ring is lost during LIM molding, which will damage internal parts and cause cost waste. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide an ultra-thin and highly waterproof connector, which aims to solve the problem that the silicone ring in the prior art is directly LIM-molded on the tongue window, resulting in loss of internal parts and cost waste.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A connector comprises: a housing having an accommodating cavity, wherein a side portion of the housing is provided with an opening portion communicating with the accommodating cavity;

[0007] Also included is a connecting base connected to the accommodating cavity, one end of the connecting base extending into the accommodating cavity and passing through the opening to connect with the circuit board, and the other end of the connecting base extending out of the accommodating cavity;

[0008] The fixed shell is sleeved on the connecting seat and is provided with a step; a silicone ring is provided on the fixed shell and surrounds the step;

[0009] One end of the connecting seat away from the shell extends outside the fixing shell.

[0010] Furthermore, in some embodiments, the shell includes a first shell (upper iron shell) and a second shell (lower iron shell), and the first shell and the second shell surround and form a accommodating cavity; one end of the connecting seat is embedded in the accommodating cavity formed by the first shell and the second shell.

[0011] Furthermore, in some embodiments, a surrounding silicone ring is provided on the step of the fixed shell, and the silicone ring covers the step surface (top surface) of the step.

[0012] Furthermore, in some embodiments, the connecting seat includes a tongue plate seat, the fixed shell is sleeved on the tongue plate seat, and one end of the tongue plate seat (connecting end) away from the first shell extends outside the fixed shell;

[0013] The flat area of ​​the end of the fixed shell close to the tongue plate seat is smaller than the flat area of ​​the end of the fixed shell away from the tongue plate seat;

[0014] The fixed shell is arranged on one end of the tongue plate seat close to the first shell body.

[0015] Furthermore, in some embodiments, the connecting seat includes a terminal assembly, a middle partition is sandwiched between the terminal assemblies, and a group of matching symmetrical first reinforcement plates and second reinforcement plates are provided on both sides of the middle partition; the frame cavity composed of the first reinforcement plate and the second reinforcement plate surrounds the outside of the terminal assembly.

[0016] Furthermore, in some embodiments, a set of symmetrically matched first terminal carriers and second terminal carriers are provided on both sides of the terminal assembly connection portion (front end), and the first terminal carriers and the second terminal carriers are engaged with each other to cover the first reinforcement sheet and the second reinforcement sheet;

[0017] The connecting portion (front end) of the terminal assembly is buried between the first terminal carrier and the second terminal carrier engaging body; the first terminal carrier and the second terminal carrier are embedded and formed in the tongue plate seat.

[0018] Furthermore, in some embodiments, the connection base further includes a third terminal carrier and a fourth terminal carrier;

[0019] A set of symmetrically matched third terminal carriers and fourth terminal carriers are provided on both sides of the terminal assembly welding end (rear end), and the terminal assembly welding end is buried between the third terminal carrier and the fourth terminal carrier clamping body; a plastic body is provided on the side of the fourth terminal carrier away from the third terminal carrier.

[0020] Furthermore, in some embodiments, a positioning post extending outwardly and protruding is provided on a side of the plastic body away from the fourth terminal carrier, and a positioning hole symmetrically matched with the positioning post is opened on the first shell, and the positioning post is passed through the positioning hole.

[0021] Furthermore, in some embodiments, the combination of the third terminal carrier, the fourth terminal carrier and the plastic body is disposed in the accommodating cavity formed by the first shell and the second shell.

[0022] The present invention is applied to a Type C highly waterproof connector. During assembly, a silicone ring is first molded on the step of a fixed shell, the connecting base is installed in the shell, and finally the fixed shell is sleeved on the connecting base. During production, the silicone ring is molded on the fixed shell separately. When the silicone ring fails to be molded properly, only the fixed shell needs to be discarded, thereby reducing the situation where the connecting base is directly molded on the connecting base and causing loss. The waterproof effect is achieved by directly extruding the surface of the silicone ring through the mechanism panel, eliminating the setting of the traditional iron shell window, saving space for the mechanism panel, reducing thickness, and allowing the entire device to be made thinner. The elimination of the window iron shell saves space for the mechanism panel, reducing thickness, and allowing the entire device to be made thinner. The waterproof LIM silicone ring is extruded on the mechanism panel from the front, using a separate LIM molding process, which can save the loss of component materials during the overall molding process. This saves the thickness of the mechanism panel and saves the loss of other materials during LIM molding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] It should be noted that the embodiments and features in the present application can be combined with each other without conflict. In order to further understand the features, technical means and specific purposes and functions of the present application, the advantages and spirits of the present application are analyzed through the following detailed description of the present application combined with the drawings and specific embodiments.

[0037] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "front", "back" and the like used herein are for illustrative purposes only and are not the only embodiment.

[0038] Referring to the drawings, the present application provides a connector, which includes a shell 20 with an accommodating cavity 29, and the side of the shell is provided with an opening part 54 in communication with the accommodating cavity; a connecting seat 11 is connected to the accommodating cavity 29, one end of the connecting seat 11 extends into the accommodating cavity 29 and is connected to a circuit board 52 through the opening part 54, and the other end of the connecting seat 11 extends out of the accommodating cavity 29.

[0039] In another embodiment of the present application, the shell 20 includes a first shell 21 (upper iron shell) and a second shell 22 (lower iron shell), and the first shell 21 and the second shell 22 form an accommodating cavity 29; the second shell 22 is provided with an opening part 54 in communication with the accommodating cavity 29, and one end of the connecting seat 11 is embedded and arranged in the accommodating cavity 29 formed by the first shell 21 and the second shell 22.

[0040] The connecting seat 11 is connected to the accommodating cavity 29, one end of the connecting seat 11 extends into the accommodating cavity 29 and is connected to the circuit board 52 through the opening part 54, and the other end of the connecting seat 11 extends out of the accommodating cavity 29;

[0041] In other words, the connecting base 11 is installed in the accommodating cavity 29 , a first section of the connecting base 11 extends into the accommodating cavity 29 , and the other end of the connecting base 11 extends out of the accommodating cavity 29 .

[0042] Furthermore, in one embodiment, the connecting seat 11 includes a tongue plate seat 12, the fixed shell 31 is mounted on the tongue plate seat 12, and the end of the tongue plate seat 12 (connection end) away from the first shell 21 extends outside the fixed shell 31; a step 32 is provided in the middle of the fixed shell 31, and a silicone ring 33 is provided on the fixed shell 31, and the silicone ring 33 surrounds the step 32.

[0043] Specifically, during assembly, the silicone ring 33 is first molded on the step 32 of the fixed shell 31, the connecting seat 11 is installed in the accommodating cavity 29, and finally the fixed shell 31 is sleeved on the connecting seat 11, the first shell 21 is installed on the circuit board 52, and at the same time, a section of the connecting seat 11 passes through the opening 54 and is connected to the circuit board 52. During production, the silicone ring 33 is molded on the fixed shell 31 separately; when the silicone ring 33 is unqualified, only the fixed shell 31 needs to be removed, thereby reducing the situation where the connecting seat 11 is directly molded on the connecting seat 11 and the loss is caused; and the surface of the silicone ring 33 is directly squeezed by the mechanism panel to achieve a waterproof effect, thereby eliminating the setting of the traditional iron shell window, saving space for the mechanism panel, reducing the thickness, and the whole machine can be made thinner.

[0044] Furthermore, the fixing shell 31 is sleeved on an end of the tongue plate seat 12 close to the first shell 21 .

[0045] In another embodiment of the present invention, the fixed shell 31 includes a first annular portion 56 and a second annular portion 55. The planar surface area of ​​the first annular portion 56 is smaller than the planar surface area of ​​the second annular portion 55. The second annular portion 55 is fixedly connected to the first and second shells 21 and 22. Optionally, the second annular portion 55 is fixedly connected to the first and second shells 21 and 22 via welds. A step 32 is formed between the first annular portion 56 and the second annular portion 55. Specifically, the planar surface area of ​​the first annular portion 56 is smaller than the planar surface area of ​​the second annular portion 55, thereby forming the step 32 between the first annular portion 56 and the second annular portion 55, facilitating the molding of the silicone ring 33 onto the fixed shell 31.

[0046] In another embodiment of the present invention, the edges of the first annular portion 56 and the second annular portion 55 are equidistant. Specifically, the step 32 between the upper edge of the first annular portion 56 and the lower edge of the second annular portion 55 is of uniform width. This ensures that the silicone ring 33 is evenly formed along the first annular portion 56, improving sealing performance.

[0047] In another embodiment of the present invention, a stopper 57 is vertically extended from a section of the first annular portion 56 facing away from the second annular portion 55, and the stopper 57 extends close to the connector 11. Specifically, when the plug is connected to the connector 11, the free end of the plug abuts against the stopper 57, thereby acting as a stop.

[0048] In another embodiment of the present invention, the second annular portion 55 includes two parallel flat surfaces connected to arcuate surfaces at both ends of the two flat surfaces. The two flat surfaces of the second annular portion 55 are fixedly connected to the first shell 21 and the second shell 22 by welding. Specifically, the weld points are arranged on the two flat surfaces, which simplifies welding. Furthermore, the weld points are evenly spaced on the two flat surfaces of the second annular portion 55.

[0049] In another embodiment of the present invention, the width of the silicone ring 33 is smaller than the width of the first annular portion 56. In this way, when the mechanism panel squeezes the surface of the silicone ring 33 to deform the silicone ring 33, the first annular portion 56 always maintains a full support effect on the silicone ring 33.

[0050] Optionally, a silicone ring 33 is provided around the step 32 of the fixed housing 31, covering the stepped surface (top surface) of the step 32. The fixed housing 31 is assembled within the base 51, and the silicone ring 33 is used to seal the gap between the outer surface of the fixed housing 31 (panel housing) and the base 51 of the device.

[0051] Furthermore, in one embodiment, the connecting seat 11 includes a terminal assembly 13, a middle partition 14 is sandwiched between the terminal assemblies 13, and a group of matching symmetrical first reinforcement plates 41 and second reinforcement plates 42 are provided on both sides of the middle partition 14; the frame cavity formed by the first reinforcement plate 41 and the second reinforcement plate 42 surrounds the outside of the terminal assembly 13. In other words, the terminal assembly 13 is arranged in the frame cavity formed by the first reinforcement plate 41 and the second reinforcement plate 42.

[0052] A group of symmetrically matched first terminal carriers 15 and second terminal carriers 16 are provided on both sides of the connection part (front end) of the terminal assembly 13. The first terminal carrier 15 and the second terminal carrier 16 are engaged and cover the first reinforcement plate 41 and the second reinforcement plate 42; the connection part (front end) of the terminal assembly 13 is buried between the engaging bodies of the first terminal carrier 15 and the second terminal carrier 16; the first terminal carrier 15 and the second terminal carrier 16 are embedded and formed in the tongue plate seat 12.

[0053] The connector 11 also includes a third terminal carrier 17 and a fourth terminal carrier 18. The soldering end (rear end) of the terminal assembly 13 is disposed on the circuit board 52. A pair of symmetrically matched third and fourth terminal carriers 17, 18 are positioned on either side of the soldering end (rear end) of the terminal assembly 13. The soldering end (rear end) of the terminal assembly 13 is embedded between the engaging bodies of the third and fourth terminal carriers 17, 18. A plastic body 37 is provided on the side of the fourth terminal carrier 18 facing away from the third terminal carrier 17.

[0054] Furthermore, in one embodiment, a positioning post 19 is provided on a surface of the plastic body 37 facing away from the fourth terminal carrier 18, extending outwardly. A positioning hole 26 is defined in the first housing 21, symmetrically matching the positioning post 19. The positioning post 19 is inserted into the positioning hole 26. The combination of the third terminal carrier 17, the fourth terminal carrier 18, and the plastic body 37 is disposed in a receiving cavity 29 formed by the first housing 21 and the second housing 22.
