Description

Connector

【Technical field】

The utility model relates to a connector, in particular to a connector capable of ensuring that the copper ring is reliably grounded.

【Background technique】

As shown in Figure 7 is a known audio connector, the connector at least includes a housing 70, a copper ring 80 and a grounding piece 90 (please refer to shown in Figure 8); wherein:

The casing 70 is generally rectangular and hollow, and one end is formed with a protruding portion 71 protruding toward the outer wall, and a socket 72 is formed in the protruding portion 71 for installing and accommodating the aforementioned copper ring 80; and the grounding member 90 is generally U-shaped metal sheet body, which has two opposite arms, wherein the inner end of one arm extends a bent electrical contact portion 91 inward, and the inner end of the other arm extends outward in a right angle direction to form a pin 92; moreover, the bottom edge of the outer end of the grounding member 90 extends outwards to form a tongue 93; and the grounding member 90 is located at one end of the protruding portion 71 in the housing 70, and its electrical contact portion 91 will correspond to Located inside the jack 72 , its pin 92 protrudes out of the housing 70 for assembly of the plug-in, and the tongue 93 of the grounding member 90 protrudes to the inner hole wall of the jack 72 .

The outer diameter of the copper ring 80 matches the inner diameter of the socket 72, and the inner end of the copper ring 80 is formed with an enlarged portion 81 with a bevel and its maximum outer diameter is slightly larger than the inner diameter of the socket 72, so that the inner end of the copper ring 80 can still enter the socket smoothly. In the hole 72, when the copper ring 80 enters the socket 72 completely, its expanded portion 81 will squeeze into the hole wall of the socket 72 to form a tight fit state (see Figure 9); at the same time, the copper ring 80 The inner side end of the grounding member 90 is also in contact with the tongue 93.

It can be seen from the above that the copper ring 80 of the aforementioned connector must form electrical contact with the grounding member 90, but the contact relationship between the two is only limited to the tongue 93 extending from the outer end of the grounding member 90 and the inner end of the copper ring 80. There is a very limited contact area between the audio connectors. Since the current signal often passes through the copper ring 80 and the grounding piece 90 when the audio connector is used, the temperature may rise. When the temperature is high, the possibility of deformation is relatively increased. In this situation, poor contact between the grounding member 90 and the copper ring 80 may occur, thereby affecting the normal operation of the connector.

【Content of utility model】

The main purpose of the utility model is to provide a connector that can ensure that the copper ring and the grounding piece are in contact.

The main technical means adopted for achieving the aforementioned purpose is to make the aforementioned connector include:

A housing, generally rectangular and hollow, with a protruding portion protruding toward the outer wall formed at one end, and an insertion hole is formed in the protruding portion;

A copper ring is set in the socket of the aforementioned casing, and a concave neck in the shape of a ring groove is formed on the inner end of the copper ring;

A grounding piece, one end of the grounding piece is respectively formed with a contact piece at two opposite positions, and the two contact pieces are suitable for being oppositely clamped on the concave neck of the copper ring to form an electrical contact;

In the aforementioned structure, the two contact pieces in the grounding piece are relatively clamped on the concave neck of the copper ring, so it can ensure that the copper ring and the grounding piece are in electrical contact, and the contact relationship will not be affected by high temperature deformation or external force .

【Detailed ways】

A preferred embodiment of the present utility model is shown in Fig. 1, mainly is to be provided with a copper ring 20 and a grounding member 30 in a housing 10; Wherein:

The casing 10 is generally rectangular and hollow, and one end thereof is formed with a protruding portion 11 that protrudes toward the outer wall. A socket 12 is formed in the protruding portion 11 for mounting and accommodating the copper ring 20. The inner end of the socket 12 is An inwardly recessed groove 13 is formed on the opposite wall of the hole.

The ground member 30 has upper and lower sheets and two side sheets, wherein one side sheet and the upper sheet are disconnected, and the other sheets are continuous, and the inner side of the one side sheet of the ground member 30 extends inwardly The bent electrical contact portion 31, the inner end of the other side plate extends outwards at right angles to form a pin 32; moreover, the grounding member 30 is formed by extending outwards from the outer ends of the upper and lower plates respectively. A contact piece 33, a gap is formed between the free end of the contact piece 33 and the upper and lower pieces, so that it forms a shrapnel shape, and the contact piece 33 forms protruding contact portions 330 on the opposite inner sides.

The above-mentioned grounding member 30 is located at one end of the protruding portion 11 in the housing 10, the contact piece 33 on the upper and lower plates is located in the groove portion 13 on the inner side of the jack 12, and the electrical contact portion 31 is located on the inner side of the socket 12. Inside the jack 12 , the pin 32 passes through the casing 10 .

The outer diameter of the copper ring 20 matches the inner diameter of the socket 12, an enlarged portion 21 with a slope and its maximum outer diameter is slightly larger than the inner diameter of the socket 12 is formed at the middle section, and an inward concave is formed at the inner end to reduce the inner diameter. The concave neck 22 is adapted to correspond to the two contact pieces 33 on the grounding element 30 .

Can understand the detailed structure of a preferred embodiment of the present utility model by the above description, as for its combination mode is described in detail as follows:

First, the copper ring 20 is pressed into the insertion hole 12 of the housing 10 , when the copper ring 20 enters the insertion hole 12 , its expanded portion 21 will squeeze into the hole wall of the insertion hole 12 to form a tight fit. Then put the grounding piece 30 into the opening on the side wall of the housing 10, and install it on the end near the protruding part 11 in the housing 10, and the contact piece 33 at the outer end of its upper and lower pieces will be positioned at the jack. 12 inside the groove portion 13 (see Figure 2), and the two contact pieces 33 will correspond to the concave neck 22 of the copper ring 20, and its contact portion 330 will be relatively clamped on it (see Figure 3 shown) to constitute a definite electrical contact relationship.

See also shown in Fig. 4, 5, 6, it is another preferred embodiment of the present utility model, its basic composition structure, as housing 10, copper ring 20 etc. are all roughly the same as the previous embodiment, the difference lies in the The form of the contact piece 33' of the grounding element 30' is slightly different:

The ground member 30' mainly still has upper, lower and two side plates, and the outer ends of the upper and lower plates also extend outwards respectively to form a contact piece 33'. The contact piece 33' is narrow and long. The side is parallel to the edges of the upper and lower pieces, and forms a gap with the upper and lower pieces, making it into an elastic piece, and the end of the long side of the contact piece 33 ′ is slightly bent inward to form the contact portion 330 ′. When the grounding piece 30' is installed in the housing 10, the grounding piece 30' will be located at one end of the housing 10 near the protrusion 11, and its contact piece 33' will be located in the groove 13 on the inner side of the socket 12. The contact portion 330 ′ of the contact piece 33 ′ is then relatively clamped in the concave portion 22 of the copper ring 20 to form a positive electrical contact.

As can be seen from the above, the connector of the present invention makes the two contact pieces in the grounding piece relatively clamped on the concave neck of the copper ring, so that the copper ring and the grounding piece can truly form electrical contact, so that , can avoid the contact relationship affected by high temperature deformation or external force, and effectively solve the problem that the traditional connector may affect normal operation due to poor contact.
