Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, specifically to an electronic connector with a glue injection pinhole structure. Background Technology

[0002] Electronic connectors are devices for transmitting electronic signals. They provide a separable interface for connecting two secondary electronic systems. They are components that establish electrical connections between circuits or electronic devices, serving to connect or disconnect current or signals. This connection can be temporary, allowing for easy plugging and unplugging, or it can be a permanent junction between electrical equipment or wires.

[0003] Existing electronic connectors mostly consist of a housing, an integrated tongue, and an insulating base, all housed within the housing. Their structure is simple. To prevent water from seeping between the housing and the integrated tongue during use and causing water damage to the internal circuitry, a waterproof sealant is needed between them. Traditionally, this waterproof sealant is applied in an open manner during assembly, allowing it to flow naturally. This method is inefficient and prone to incomplete penetration and inadequate sealing, leading to cracking under external force after sealing. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an electronic connector with a glue injection pinhole structure.

[0005] The objective of this utility model is achieved through the following technical solution: an electronic connector with a glue injection pinhole structure, comprising a housing, an integral tongue and an insulating seat both housed within the housing, a glue injection space between the integral tongue and the insulating seat, a glue injection pinhole being provided at the end of the insulating seat away from the integral tongue, a first glue injection clearance groove being provided at the end of the housing near the glue injection pinhole, and a second glue injection clearance groove being provided at the end of the insulating seat near the integral tongue, the first glue injection clearance groove, the glue injection pinhole, the second glue injection clearance groove and the glue injection space being sequentially connected, and the housing being filled with a pin-injection waterproof glue integrally formed in the glue injection space and the second glue injection clearance groove and adhering to the inner wall of the housing.

[0006] Preferably, the insulating seat includes a first insulating connecting seat and a second insulating connecting seat that engages with the first insulating connecting seat. The side of the first insulating connecting seat near the integrated tongue and the side of the second insulating connecting seat near the integrated tongue both abut against the injection waterproof adhesive. The injection needle hole and the second injection clearance groove are both located on the top of the first insulating connecting seat.

[0007] Preferably, the bottom of the second insulating connector has an exhaust groove on the side near the integrated tongue, and the glue injection space is connected to the outside of the housing through the exhaust groove.

[0008] Preferably, the first insulating connector has a first protrusion protruding on the side near the integrated tongue, and the second insulating connector has a second protrusion protruding on the side near the integrated tongue. The first protrusion and the second protrusion combine to form a reinforcing block with an annular outer periphery, and the outer periphery of the reinforcing block is fixedly connected to the inner wall of the housing.

[0009] Preferably, the second insulating connector has protruding locking blocks on both sides, and the first insulating connector has a receiving groove, with locking slots on both sides of the receiving groove engaging with the locking blocks.

[0010] Preferably, the integrated tongue includes a tongue sleeve and an injection-molded tongue housed within the housing. The injection-molded tongue includes a plug-in portion, a fixing portion, and an extension portion connected in sequence. The tongue sleeve is fixedly fitted onto the plug-in portion and the fixing portion, and the outer periphery of the extension portion is fixedly connected to the inner wall of the housing.

[0011] Preferably, there is an annular filling space between the tongue and the extension, and the housing is filled with a UV waterproof adhesive integrally formed in the annular filling space and adhering to the inner wall of the housing.

[0012] Preferably, the housing includes an outer shell and a middle shell fixedly connected inside the outer shell. The insulating seat and the extension are both interference-fitted with the middle shell. The needle-injected waterproof adhesive is attached to the inner wall of the middle shell.

[0013] Preferably, the outer shell has a first weld hole for laser welding to the middle shell, and the middle shell has a second weld hole for laser welding to the tongue sleeve.

[0014] The beneficial effects of this utility model are as follows: The electronic connector with a glue injection pinhole structure of this utility model adopts a shell, and an integral tongue and an insulating seat both housed in the shell. There is a glue injection space between the integral tongue and the insulating seat. A glue injection pinhole is opened at the end of the insulating seat away from the integral tongue. A second glue injection relief groove is opened at the end of the insulating seat close to the integral tongue. The first glue injection relief groove, the glue injection pinhole, the second glue injection relief groove and the glue injection space are connected in sequence. The shell is filled with a needle-injected waterproof glue integrally formed in the glue injection space and the second glue injection relief groove and attached to the inner wall of the shell. During actual assembly, after the electronic connector is assembled, a glue-applying needle is used to penetrate the first glue-applying recess and the glue-applying needle hole and extend into the second glue-applying recess. Pressure is applied to the glue-applying space to inject waterproof glue. Under pressure, the waterproof glue completely covers the glue-applying space and fills it more densely to form needle-injected waterproof glue, which improves production efficiency. Because the needle-injected waterproof glue is inside the electronic connector, the entire needle-injected waterproof glue is not easily damaged by external forces when the product is subjected to external forces, thus improving waterproof stability.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] like Figure 1-4 As shown, an electronic connector with a glue injection pinhole 1 structure includes a housing 3, an integral tongue 4 and an insulating seat 5 both housed within the housing 3, a glue injection space 2 between the integral tongue 4 and the insulating seat 5, a glue injection pinhole 1 is provided at the end of the insulating seat 5 away from the integral tongue 4, a first glue injection clearance groove 6 is provided at the end of the housing 3 near the glue injection pinhole 1, and a second glue injection clearance groove 7 is provided at the end of the insulating seat 5 near the integral tongue 4. The first glue injection clearance groove 6, the glue injection pinhole 1, the second glue injection clearance groove 7 and the glue injection space 2 are sequentially connected, and the housing 3 is filled with a pin-injection waterproof glue 8 integrally formed in the glue injection space 2 and the second glue injection clearance groove 7 and adhered to the inner wall of the housing 3.

[0022] The electronic connector with a glue injection pinhole 1 structure uses a housing 3, and an integral tongue 4 and an insulating seat 5 both housed in the housing 3. There is a glue injection space 2 between the integral tongue 4 and the insulating seat 5. The insulating seat 5 has a glue injection pinhole 1 at the end away from the integral tongue 4, and a second glue injection relief groove 7 at the end of the insulating seat 5 close to the integral tongue 4. The first glue injection relief groove 6, the glue injection pinhole 1, the second glue injection relief groove 7 and the glue injection space 2 are connected in sequence. The housing 3 is filled with a needle-injected waterproof glue 8 integrally formed in the glue injection space 2 and the second glue injection relief groove 7 and attached to the inner wall of the housing 3. During actual assembly, after the electronic connector is assembled, the glue-applying needle passes through the first glue-applying relief groove 6 and the glue-applying needle hole 1 and extends into the second glue-applying relief groove 7. Pressure is applied to the glue-applying space 2 to inject waterproof glue. Under pressure, the waterproof glue completely covers the glue-applying space 2 and fills it more densely to form the needle-injected waterproof glue 8, which improves production efficiency. Because the needle-injected waterproof glue 8 is inside the electronic connector, the entire needle-injected waterproof glue 8 is not easily damaged by external forces when the product is subjected to external forces, thus improving waterproof stability.

[0023] Furthermore, the insulating seat 5 includes a first insulating connecting seat 51 and a second insulating connecting seat 52 that engages with the first insulating connecting seat 51. The side of the first insulating connecting seat 51 near the integrated tongue 4 and the side of the second insulating connecting seat 52 near the integrated tongue 4 both abut against the needle-injected waterproof adhesive 8. The adhesive injection needle hole 1 and the adhesive injection clearance groove 7 are both opened on the top of the first insulating connecting seat 51.

[0024] Furthermore, the bottom of the second insulating connector 52 is provided with an exhaust groove 9 on the side near the integrated tongue 4. The glue injection space 2 is connected to the outside of the housing 3 through the exhaust groove 9. This prevents the air in the glue injection space 2 from being not expelled in time when the glue injection needle penetrates the glue injection needle hole 1 and extends into the second glue injection clearance groove 7 to inject glue, thus affecting the density of the waterproof glue filling. At the same time, it is helpful to confirm whether the glue amount is saturated and improve efficiency.

[0025] Furthermore, the first insulating connector 51 has a first protrusion 10 protruding on the side near the integrated tongue 4, and the second insulating connector 52 has a second protrusion 11 protruding on the side near the integrated tongue 4. The first protrusion 10 and the second protrusion 11 combine to form a reinforcing block with an outer ring. The outer periphery of the reinforcing block is fixedly connected to the inner wall of the housing 3, which improves the connection stability between the insulating connector 5 and the housing 3, and at the same time helps to prevent waterproof glue from overflowing when applying glue.

[0026] Furthermore, the second insulating connector 52 has protruding locking blocks 12 on both sides, and the first insulating connector 51 has a receiving groove 13. Both sides of the receiving groove 13 have locking slots 14 that engage with the locking blocks 12, so that the second insulating connector 52 can be assembled onto the first insulating connector 51, thereby improving assembly efficiency.

[0027] Furthermore, the integrated tongue 4 includes a tongue sleeve 41 and an injection-molded tongue 42 housed within the housing 3. The injection-molded tongue 42 includes a plug-in portion 421, a fixing portion 422, and an extension portion 423 connected in sequence. The tongue sleeve 41 is fixedly fitted onto the plug-in portion 421 and the fixing portion 422, and the outer periphery of the extension portion 423 is fixedly connected to the inner wall of the housing 3.

[0028] Furthermore, there is an annular filling space between the tongue sleeve 41 and the extension portion 423, and the housing 3 is filled with UV waterproof adhesive 15 integrally formed in the annular filling space and attached to the inner wall of the housing 3, which helps to further improve the waterproof effect of the electronic connector.

[0029] Furthermore, the housing 3 includes an outer shell 31 and a middle shell 32 fixedly connected within the outer shell 31. The insulating seat 5 and the extension portion 423 are both interference-fitted with the middle shell 32. The needle-injected waterproof adhesive 8 is fitted to the inner wall of the middle shell 32. The tongue sleeve 41 is fixedly connected within the middle shell 32. The first adhesive injection clearance groove 6 is formed at one end of the outer shell 31 near the adhesive injection needle hole 1. Even further, the outer periphery of the reinforcing block is interference-fitted with the inner wall of the housing 3, and the UV waterproof adhesive 15 is fitted to the inner wall of the middle shell 32.

[0030] Furthermore, the outer shell 31 has a first welding hole 16 for laser welding to the middle shell 32, and the middle shell 32 has a second welding hole 17 for laser welding to the tongue sleeve 41. The middle shell 32 is laser welded to the tongue sleeve 41 through the second welding hole 17, and the outer shell 31 is laser welded to the middle shell 32 through the first welding hole 16, which improves the connection stability between the outer shell 31 and the middle shell 32, and between the middle shell 32 and the tongue sleeve 41, and also helps to improve assembly efficiency.

[0031] Furthermore, rivets 18 protrude from the bottom of both sides of the outer casing 31, and the rivets 18 are riveted to the bottom of the insulating base 5. The outer casing 31 is fixed to the insulating base 5 by the rivets 18, thereby improving the stability of the connection between the outer casing 31 and the insulating base 5.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
