the short side surface part is provided with a grounding plate socket 5, and the grounding plate 3 is inserted from the grounding plate socket 5;

a barrier 4 is arranged between the contact assemblies 2;

Specifically, the connector is an integrated structure which is integrally formed through a connector manufacturing die and comprises a shell 1, a contact assembly 2 and a grounding piece 3, wherein a plurality of surfaces of the shell 1 are divided and distinguished by the lengths of sides, long sides are marked as long side surface parts, short sides are marked as short side surface parts, and the long side surface parts and the short side surface parts are respectively provided with two surfaces; in addition, the long side surface portion of the contact assembly 2 on the side from which it protrudes is used as the front surface, the other long side surface portion is used as the back surface, and the grounding plate 3 is inserted into the grounding plate insertion opening 5 from the side. In addition, one surface of the contact assembly 2 is referred to as a bottom surface portion, and the other surface opposite to the bottom surface portion is referred to as a top surface portion.

In the embodiment, the flatness and stability of the connector are improved by inserting the grounding plate from the side edge of the connector; meanwhile, the contact area between the grounding piece 3 and the welding surface is increased by inserting the grounding piece 3 from the side edge of the connector, so that the connection firmness of the connector is improved; in addition, the side insertion mode of the grounding plate 3 is also suitable for a vertical connector and a horizontal connector, and the application adaptability and the application breadth are further improved.

The present embodiment can effectively prevent the problem of the contact assembly 2 being skewed by providing the barrier ribs 4 that are spaced apart.

In this embodiment, the top surface portion is processed by drawing out materials, so as to form a first cavity recessed inwards, thereby avoiding thick shrinkage of the glue position and further avoiding shrinkage of the inner side of the connector.

The contact assembly 2 is a component of the connector for making and breaking electrical connection. In some embodiments of the present invention, as shown in fig. 1 to 4, the contact assemblies 2 are spaced apart and mounted on the bottom surface portion; the bottom surface part forms a step structure and comprises a first bottom surface part forming the step structure and a second bottom surface part positioned on the step; the first bottom surface part and the second bottom surface part are respectively provided with a plurality of first grooves and second grooves which are distributed at intervals.

By the step-like and third groove arrangement, the bonding strength between the contact assembly 2 and the soldering surface can be improved. Because the stepped surface and the third groove make the volume of the welding surface formed between the contact assembly 2 and the tin plate larger than that of the welding surface formed by the surface of the conventional planar contact assembly 2, the connection firmness is increased, and the reliability of the connector is further enhanced.

In this embodiment, as shown in fig. 1-3, the strip-shaped portion of the contact assembly 2 includes a first portion located in the second cavity of the bottom portion and a second portion extending out of the second cavity and extending from the long-side surface portion side. In this embodiment, as shown in fig. 1-3, the first portion and the second portion of the contact assembly 2 extend in the same direction, and are perpendicular to the plane of the long side surface portion.

The welding surface is formed between the PIN needle and the tin plate and is used as a support, namely: the portion that PIN needle and tin plate are connected is the face of welding, and the PIN needle is higher than the tin plate plane 0.20mm moreover, and that is to say, the face of welding height that forms between PIN needle and the tin plate is 0.20mm, and the design can avoid the connector main part to contact the tin plate like this to prevent to burst tin and avoid causing the short circuit between the PIN needle.

In some embodiments of the present invention, as shown in FIGS. 1-3 and 8, the barrier 4 includes a first barrier 41, a second barrier 42, and a third barrier 43; the first barrier 41 and the second barrier 42 are of an integral structure and enclose the bottom surface part into a second cavity for accommodating the contact assembly; a third barrier 43 is located between the contact assemblies in the second cavity. The first barrier 41 and the third barrier 43 each comprise a plurality of barriers and are spaced apart from each other at the bottom surface.

In the embodiment of the present invention, third barrier ribs 43 are disposed on the second bottom surface portion at intervals, and the top surface of the third barrier ribs 43 is higher than the second bottom surface portion. By means of the third spacers 43 which are spaced apart, the risk of short-circuiting between adjacent contact assemblies 2 due to dropping of conductive debris or the like or overflow of solder is further reduced.

As a preferred embodiment of the present invention, the first barrier 41 is located at a side of the contact assembly 2 extending out of the assembly tip of the connector, for separating the contact assembly 2; a first gap is provided between the first barrier 41 and the adjacent contact assembly 2; the third barrier 43 has a second gap with the adjacent contact assembly 2.

As a preferred embodiment of the present invention, the second barrier 42 includes a side portion forming the second cavity and a back side portion on the opposite side of the first barrier 41; the back portion is located at one side of the component tail end of the contact component 2, and is used for limiting the contact component 2. In a specific embodiment, the back side portion not only can limit the contact assembly 2 to prevent the contact assembly from exceeding the contact area of the connector, but also can align the contact assembly 2 by abutting against the back side portion, thereby further optimizing the accurate alignment of the contact assembly 2 and improving the reliability of the connector.

It will be appreciated that in the embodiment of the present application, since there are a plurality of PIN needles, the first barrier 41 will separate the two PIN needles to avoid the external material from being trapped between the two PIN needles, and the first barrier 41 and the PIN needles are not in close contact, but have a gap, which allows the excessive paint to penetrate between the PIN needles and the first barrier 41 along the gap, so as to avoid the excessive paint contacting the two PIN needles when wrapping the paint layer, thereby indirectly connecting the two PIN needles through the excessive paint, and causing the short circuit between the PIN needles.

In addition, the second barrier 42 has a semi-or full-surrounding structure, which encloses the PIN inside, and the second barrier 42 can limit the PIN and control the position of the PIN. And the third barrier 43 is located the intermediate position of first barrier 41 and second barrier 42, and just separates two PIN needles equally to through this third barrier 43, can make the PIN needle be difficult for producing electric arc, be difficult for being broken down by high voltage when beating high voltage, played fine insulating effect.

In one embodiment of the present application, a barrier 4 is provided between two PIN needles, and the height of the barrier 4 is lower than that of the PIN needles, that is: the barrier 4 and the tin plate are spaced apart from each other and do not contact each other. The design of the barrier 4 is mainly used for separating the gap between the PIN needles, so as to avoid the short circuit caused by the fact that external substances are blocked between the two PIN needles; the PIN needle is not easy to generate electric arc due to the protection of the barrier 4, is not easy to break down by high voltage when the high voltage is applied, and can play an insulating effect; furthermore, when the PIN is assembled, the barrier 4 can play a limiting role, and the position of the PIN can be accurately controlled, so that the high quality of the connector is ensured.

In some embodiments of the invention, as shown in fig. 1-3, the grounding plate 3 is inserted from a side socket of the connector. The grounding plate socket 5 is L-shaped, and the grounding plate 3 is of an L-shaped or inverted T-shaped structure. Wherein, as shown in fig. 4, the grounding plate 3 comprises a barb structure which is inserted and connected with the grounding plate socket 5 and a grounding plane structure which is exposed on the bottom surface of the connector. The grounding sheet 3 is an integrated structure, and the connection structure between the barb structure and the grounding plane structure is a one-piece structure. The integrated molding of the grounding piece and the design of the one-piece structure greatly simplify the preparation process of the grounding piece, and simultaneously match the integrated structure of the grounding piece 3 with the grounding piece socket 5 inserted with the grounding piece, so that the molding process of the grounding piece socket is also greatly simplified, the production cost of the connector is further saved, and the production efficiency is improved. In addition, the barb structure of the grounding plate is an integrated structure, and the length of the barb structure is the same as the length of the grounding plate socket. Through the design of the barb structure, the inserting force between the grounding piece and the grounding piece socket can be enhanced, the grounding piece 3 is ensured not to fall off, and the stability and the reliability of the connector are further improved. Meanwhile, the grounding sheet 3 is in a side-plug connection mode and the surface of the grounding plane structure is arranged flatly, so that the grounding evenness and the stability of the connector can be further improved.

According to the invention, the notch of the inverted hook structure for clamping and inserting the grounding plate 3 is formed at the grounding plate socket 5, so that the firm connection between the grounding plate 3 and the connector can be further improved, and the grounding plate 3 is ensured not to fall off.

The ground plate structure shown in fig. 4 is merely an example of one embodiment of the present invention and is not meant to limit the present invention. For example, as a preferred embodiment of the present invention, the length of the ground blade at the ground blade receptacle 5 is less than or equal to the length of the ground blade 3 exposed to the bottom surface of the connector. In other words, the length of the ground plane structure is greater than or equal to the length of the barb structure. The invention can increase the welding surface area of the electric connection between the grounding piece and the tin plate by increasing the length of the grounding plane structure exposed on the bottom surface of the connector, thereby further improving the connection firmness and reliability of the connector. As a further preferred embodiment of the invention, the surface of the ground plane structure extends outside the connector assembly, in other words the ground plane structure of the ground plate, i.e. the ground plane, is not limited to the area of the connector assembly structure, but may extend beyond the area of the connector assembly structure.
