Description

Technical Field

[0001] The utility model relates to a type-c connection structure, in particular to a snap-on short-body type-c connection structure, and belongs to the technical field of type-c connection structures. Background Art

[0002] The motherboard clip-on short-body Type-C interface is a new type of data transmission and charging interface that has gradually become popular in recent years. In the existing technology, such as Figure 1 , including shell 1, limit buckle 2, limit slot 3, plastic body tongue 5, terminal 6, support mechanism 7, mainly used in small, thin and delicate products, so there are strict size requirements for short Type-C. Usually the standard size of Type-C interface is between 5.0mm-6.0mm, which is very small. Problems may occur during the production process:

[0003] 1. When the motherboard snap-on short-body Type-C interface is to be installed on the motherboard of the product, it must be heated before bonding or welding. When the temperature is too high, the plastic body tongue expands and contracts. Since the tongue part wrapped by the shell is relatively small and the contact surface is small, the plastic body tongue 5 will lie down.

[0004] 2. The traditional support mechanism will cause a gap between the welding position of the plug-in board of the shell and the plane of the shell, which will easily lead to poor patch during the SMT process.

[0005] To this end, a snap-on short-body type-c connection structure is proposed. Utility Model Content

[0006] In view of this, the utility model provides a snap-on short-body type-c connection structure to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the embodiment of the utility model is implemented as follows: a snap-on short-body type-c connection structure, comprising a shell, a limit buckle, a limit groove, a folding buckle, a plastic body tongue, a terminal, a support mechanism and a buckle, wherein the folding buckles are symmetrically arranged on both sides of one end of the shell, the inner side walls of the folding buckles are tightly buckled with the left and right sides of the front end of the plastic body tongue, and the bottom ends of the left and right sides of the shell are respectively provided with support mechanisms;

[0008] Wherein, the support mechanism includes a first support body, the first support body includes a first connecting section and a platform stage, the first connecting section and the platform stage are an integrally formed structure, and the horizontal plane of the platform stage is at the same horizontal plane as the bottom surface of the terminal.

[0009] Further preferably, the interior of the shell is slidably connected to the outer wall of the tongue of the plastic body.

[0010] Further preferably, the terminal is fixedly connected to the inside of the tongue of the plastic body.

[0011] Further preferably, a symmetrical limiting groove is formed at the top of the tongue piece of the plastic body.

[0012] Further preferably, buckles are respectively provided on the left and right sides of the tongue piece of the plastic body.

[0013] Further preferably, the limiting groove is internally slidably connected to a limiting buckle, and the limiting buckle and the shell are an integrally formed structure.

[0014] Further preferably: the support mechanism also includes a second support body, the second support body includes a second connecting section and a first fixed section, the second support body includes the second connecting section and the first fixed section as an integrally formed structure, a vertical angle is set between the first fixed section and the second connecting section, and the bottom horizontal plane of the first fixed section is on the same horizontal plane as the bottom surface of the terminal.

[0015] Further preferably: the support mechanism also includes a third support body, the third support body includes a third connecting section and a second fixed section, the third connecting section and the second fixed section are an integrally formed structure, a vertical angle is set between the second fixed section and the third connecting section, and the bottom horizontal plane of the third connecting section is in the same horizontal plane as the bottom end surface of the terminal.

[0016] The utility model embodiment adopts the above technical solution, which has the following advantages:

[0017] 1. The parallel part of the bottom of the support mechanism is flush with the lowest part of the terminal, forming a triangular support effect. In this way, after the support mechanism is inserted into the jack of the PCB motherboard, the bottom part of the terminal and the stage will abut against the motherboard, avoiding a gap between the welding position of the plug-in board of the shell and the shell, which may cause poor patching during the SMT process;

[0018] 2. Press down the limiting buckle and insert it into the limiting groove of the plastic body tongue, and squeeze and bend the folding buckle to fit tightly with the plastic body tongue, so as to fix and limit the plastic body tongue and tongue. By adding two buckle points at the tail of the shell, the plastic and the shell can be more stably matched, avoiding the problem that the plastic body tongue is prone to lying down after assembly when there is only a top buckle point.

The horizontal plane of the platform stage 702 is in the same horizontal plane as the bottom surface of the terminal 6. By making the platform stage 702 of the supporting mechanism 7 in the same horizontal plane as the bottom surface of the terminal 6, the flatness problem of the SMT process patch is improved, and by adding two folding buckles 4 at the tail of the shell 1, the plastic body tongue 5 and the shell 1 are more stably matched, and the problem of the plastic body tongue 5 lying down after assembly is improved.

[0035] In Example 1, specifically, the interior of the housing 1 is slidably connected to the outer wall of the plastic body tongue 5, which facilitates the rapid setting and fixing of the plastic body tongue 5 and provides protection to prevent the internal plastic body tongue 5 from bumping and causing unstable line connection.

[0036] In the first embodiment, specifically, the terminal 6 is fixedly connected to the inside of the plastic body tongue 5, so as to insulate the terminal 6 from the housing 1 and prevent the phenomenon of power on or short circuit.

[0037] In Example 1, specifically, a symmetrical limiting groove 3 is provided at the top of the plastic body tongue 5, and the outer shell 1 and the plastic body tongue 5 have a buckling structure, and the limiting buckle 2 is inserted into the limiting groove 3 provided on the plastic body tongue 5 by pressing down, and the folding buckle 4 is squeezed and bent to fit tightly with the plastic body tongue 5, so as to facilitate fixing and limiting the plastic body tongue 5.

[0038] In Example 1, specifically, buckles 8 are respectively provided on the left and right sides of the plastic body tongue 5, which can limit the position of the type-c connector and provide stability.

[0039] In Example 1, specifically, the limiting groove 3 is internally slidably connected to the limiting buckle 2, and the limiting buckle 2 and the shell 1 are an integrally formed structure. The limiting buckle 2 is inserted into the limiting groove 3 formed by the tongue piece 5 of the plastic body by pressing down, and the folding buckle 4 is squeezed and bent to fit tightly with the tongue piece 5 of the plastic body, so as to facilitate fixing and limiting the tongue piece 5 of the plastic body.

When the temperature is too high, the plastic body tongue piece 5 expands and contracts due to heat, and the contact surface is small because the tongue piece part wrapped by the shell is relatively small, and the plastic body tongue piece 5 will lie down, and the stage 702 of the supporting mechanism 7 is made to be at the same horizontal plane as the bottom plane of the terminal 6, a triangular supporting effect is formed. In this way, after the supporting mechanism 7 is inserted into the jack of the PCB main board, the bottom of the terminal 6 and the stage 702 will abut on the main board, avoiding the problem of gaps between the welding position of the plug board of the shell 1 and the plane of the shell 1, which leads to poor patch quality during the SMT process;
