Description

Technical Field

[0001] This utility model belongs to the field of audio plug technology, and specifically relates to an audio connector structure. Background Technology

[0002] Traditional audio connectors typically have numerous components and generally use sleeves for clamping and securing cables. The sleeves are secured with snap-fit ​​mechanisms, which not only complicates assembly and reduces efficiency, but also results in existing conventional solderless audio connectors that use screws to pierce the outer sheath and press against the cable's shielding and grounding layer. Because screw length variations cannot guarantee grounding conductivity, this often leads to defective products. Furthermore, the commonly used iron and stainless steel screws result in significant conductivity loss for small signals. This paper proposes an improvement to this structure, offering a solderless audio connector that is easy to install, provides excellent grounding, and boasts high conductivity.

[0029] like Figures 1-5As shown, the audio connector structure of this embodiment includes an upper cover 1, a lower cover 2, connector pins 3, and connector pins 4. The upper end of the connector pin 3 has a cable groove 30. The connector pin 3 passes through the lower cover 2 and is riveted to it. The connector pin 4 is riveted to the inside of the upper cover 1, and the connector pin 4 is opposite to the cable groove 30. When the upper cover 1 and the lower cover 2 are connected by bolts, a connecting groove 5 is formed between the upper cover 1 and the lower cover 2. One end of the connecting groove 5 communicates with the outside of the upper cover 1 and the lower cover 2, and the other end of the connecting groove 5 communicates with the cable groove 30. The lower end of the connector pin 4 extends at least partially into the cable groove 30, and the cable is electrically connected to the inside of the connector pin 3. The connector pin 4 is used to pierce the outer sheath of the cable and press against the cable shield to achieve grounding.

[0030] Specifically, the connector pin 3 has a guide pin inside, which extends into the cable groove 30 for connection with the cable. The connector pin 3, the guide pin, and the connector pin 4 are made of copper, while the upper end cover 1 and the lower end cover 2 are made of iron.

[0031] In this design, the upper end cover 1 and the connector pin 4 are pre-riveted, and the lower end cover 2 and the connector pin 3 are also pre-riveted. During installation, one end of the cable is first inserted into the cable groove 30, and then the upper end cover 1 with the connector pin 4 is placed on the lower end cover 2, allowing the cable to extend from the connecting groove 5. Finally, it is secured with bolts. During installation, the connector pin 4 of the upper end cover is used to pierce the outer sheath of the coaxial cable to contact the cable shielding ground layer, achieving a solderless effect and also playing a certain positioning role. With the cooperation of the upper end cover 1, the lower end cover 2, and the bolts, the cable is stably connected to the connector pin 3. This audio connector has a relatively simple structure, which helps to reduce production costs, is easy to install, reduces assembly difficulty, and improves assembly efficiency.

[0032] Specifically, the lower end of the connector 4 is provided with a triangular barb, which serves two purposes: firstly, to increase the contact area between the connector 4 and the shielding grounding layer of the cable, thereby improving the signal conduction between the transmission signal electrode and the shielding grounding electrode; and secondly, to reinforce the connection with the cable and prevent the cable from falling off.

[0033] like Figures 1-3 As shown, preferably, the audio connector structure further includes a pressure cover 6, which is riveted to the inside of the upper cover 1 and also riveted and fixed by a connector pin 4. The connector pin 4 passes through the pressure cover 6 and extends into the inside of the pressure cover 6. The lower end of the pressure cover 6 cooperates with the upper end of the connector pin 3 to press the cable.

[0034] Specifically, the pressure cap 6, the connector pin 4, and the connector lead 3 are coaxially arranged. The pressure cap 6, the connector pin 4, and the upper end cap 1 are pre-riveted together.

[0035] The lower end of the pressure cap 6 engages with the upper end of the connector pin 3 to wrap and press the cable, which helps to further position the cable and prevents the cable from easily coming out of the cable groove 30.

The size of the upper pressing groove 61 and the lower pressing groove 31 when they are enclosed is slightly smaller than the diameter of the cable, which helps to ensure that the pressure cover 6 and the connector 3 clamp and fix the cable.

[0037] Specifically, the pressing groove 31 penetrates the side wall of the connector pin 3, and the axis of the pressing groove 31 is perpendicular to the axis of the cable groove 30; the upper end of the cable groove 30 and the upper end of the pressing groove 31 both penetrate the upper end of the connector pin 3, so that the connector pin 4 can extend into the cable groove 30.

[0038] The upper pressure groove 61 and the lower pressure groove 31 are provided to press down the bending of the cable, which helps to change the direction of the cable, and also helps to strengthen the clamping and fixing of the cable.

[0039] like Figure 5 As shown, preferably, the inner diameter of the pressure cap 6 is adapted to the outer diameter of the upper end of the connector 3, so that the pressure cap 6 is used to fit onto the outer wall of the upper end of the connector 3.

[0040] Specifically, when the pressure cap 6 is used to fit over the outer wall of the upper end of the connector pin 3, the upper pressure groove 61 and the lower pressure groove 31 are arranged opposite to each other to wrap around the outside of the cable.

[0041] The pressure cap 6 is sleeved on the outside of the connector pin 3, which helps to reduce the overall thickness of the audio connector and makes it easier for the connector to be used in narrower areas. On the other hand, the upper pressure groove 61 and the lower pressure groove 31 are interference-fitted to wrap and fix the cable, thereby strengthening the fixation.

[0042] like Figures 1-3As shown, preferably, the upper sidewall of the connector 3 is provided with a first mating step surface 32, and the lower end of the cover 6 is provided with a second mating step surface 62.

[0043] like Figures 1-4 As shown, preferably, the first mating step surface 32 is an inclined surface, which is inclined from top to bottom toward the axis away from the connector pin 3.

[0044] When the upper end cover 1 with the connector pin 4 and the pressure cap 6 is placed on the lower end cover 2, the first mating step surface 32 contacts the second mating step surface 62 and abuts against it, which means that the two are in the correct position and bolt installation can be carried out. In other words, the setting of the first mating step surface 32 and the second mating step surface 62 is conducive to positioning during installation and improves assembly efficiency. Example

The connector pin 4 is riveted to the inside of the upper cover 1 and is opposite to the cable groove 30. When the upper cover 1 and the lower cover 2 are connected by bolts, a connecting groove 5 is formed between the upper cover 1 and the lower cover 2. One end of the connecting groove 5 communicates with the outside of the upper cover 1 and the lower cover 2, and the other end of the connecting groove 5 communicates with the cable groove 30. The lower end of the connector pin 4 extends at least partially into the cable groove 30.

[0046] Specifically, the connector pin 3 has a guide pin inside, which extends into the cable groove 30 for connection with the cable. The connector pin 3, the guide pin, and the connector pin 4 are made of copper, while the upper end cover 1 and the lower end cover 2 are made of iron.

[0047] During installation, first insert one end of the cable into the cable groove 30, then place the upper end cover 1 with the connector pin 4 onto the lower end cover 2, so that the cable extends out from the connecting groove 5, and finally fix it with bolts. The signal pole and the shielding ground pole are connected by the built-in copper connector pin.

[0048] like Figure 5As shown, preferably, the audio connector structure further includes a cover 6, which is riveted to the inside of the upper cover 1, and the connector pin 4 passes through the cover 6 and extends into the inside of the cover 6.

[0049] Specifically, the pressure cap 6, the connector pin 4, and the connector foot 3 are coaxially arranged. The lower end of the pressure cap 6 cooperates with the upper end of the connector foot 3 to wrap and press the cable, which helps to further position the cable and prevent the cable from easily coming out of the cable groove 30.

[0054] Specifically, the screw hole of the upper end cover is slightly larger than the protruding ring at the screw hole of the lower end cover. When the cover is closed, the upper end cover is aligned with the protruding ring, which plays an overall positioning role and prevents the upper end cover and the lower end cover from being misaligned during installation.

[0055] Preferably, the upper end cover 1 is provided with an upper groove, and the lower end cover 2 is provided with a lower groove, the upper groove and the lower groove forming a connecting groove 5.
