Description

The structure of the electrical connector (Part 2)

The present invention provides an electrical connector structure, in particular, an electrical connector structure with simple manufacturing process, good structural strength, stable plug-in state and stable signal.

According to the company, Slimline cable components are passive copper cable components that use twinax technology and are foldable and highly scalable. Their thinness and high performance make them ideal for storage, networking, and SAS and PCIe interconnects for high-performance computing applications. Twinax provides excellent crosstalk performance and low insertion loss. The serial version of the SCSI (Small Computer System Interface) interface is called SAS (Serial Attached SCSI), which is a new interface that combines the advantages of SATA and SCSI.

However, the metal conductor of the Slimline cable assembly is shorter and narrower, and poor connection often occurs. When the plug connector and the socket connector are connected and poor connection occurs, no matter how excellent the transmission characteristics of the Slimline cable assembly are, it is impossible to function normally in the case of poor contact, and the size of the metal conductor is a fixed specification and cannot be changed.

Therefore, most companies add an outer baffle to the insulating gel. When the plug connector and the socket connector are connected, the baffle on the plug connector extends to one side of the socket connector, so the baffle can be used to limit the swing of the socket connector. However, this can only prevent the socket connector from swinging up and down and shaking left and right. The metal conductor of the Slimline cable assembly is very short, so once the front and back position is offset, it will also cause poor signal problems.

Furthermore, the above-mentioned method of improving the insulating colloid will make it difficult to manufacture the mold of the insulating colloid, which will greatly increase the manufacturing cost. If the insulating colloid is improved with multiple pieces, it will also produce defects in structural strength.

Therefore, how to solve the above-mentioned problems and deficiencies in usage is the direction that the inventor of this invention and related manufacturers in this industry are eager to study and improve.

Therefore, in view of the above-mentioned deficiencies, the inventor of this invention has collected relevant information, evaluated and considered various aspects, and used many years of experience accumulated in this industry, and after continuous trials and modifications, he finally designed the structure of this electrical connector with simple manufacturing process, good structural strength, stable plug-in state, and stable signal.

The main purpose of the present invention is to use the riveting design of the inner and outer colloid bodies, and to provide an upper stopper, a side stopper and a stopper rib on the stopper structure of the clamping colloid body, so as to simultaneously stop the socket connector in the up and down directions, left and right directions and front and back directions, thereby ensuring the structural strength and improving the plugging stability.

To achieve the above-mentioned purpose, the main structure of the present invention includes: a tongue plate portion, a plurality of tongue plate joint portions, an inner colloid, an outer colloid, a clamping colloid, a mounting seat, an elastic element, a plurality of colloid joint portions, a plurality of positioning members, two limiting structures including an upper stop portion and a side stop portion, a plug-in slot, and at least one limiting rib. The tongue plate joint part is formed on the tongue plate part, the inner colloid is arranged at one end of the tongue plate part, the outer colloid is arranged to cover the outer side of the inner colloid, the clamping colloid is integrally formed at one end of the outer colloid and abuts against the surface of the tongue plate part, the mounting seat is integrally formed on the clamping colloid, the elastic element is arranged on the mounting seat, the colloid joint part is formed on the clamping colloid and is aligned with the tongue plate joint part. The positioning piece is fixed on the tongue plate joint and the colloid joint, the limiting structure is integrally formed on both sides of the mounting seat, the upper blocking portion is located above the clamping colloid, the side blocking portion is located on one side of the clamping colloid, the plug-in slot is formed between the clamping colloid and the limiting structure, and the limiting rib is integrally formed on one side of the upper blocking portion adjacent to the plug-in slot to support the limiting socket connector.

The present invention combines the insulating plastic body of the Slimline connector with an inner plastic body and an outer plastic body, and uses a positioning piece to penetrate the fixed tongue plate joint part and the plastic body joint part, thereby effectively controlling the manufacturing cost and taking into account the structural strength of the connector. The clamping plastic body at the front end of the outer plastic body has a limit structure that can prevent the socket connector from shaking. The limit structure uses an upper baffle to prevent it from swinging up and down, a side baffle to prevent it from swinging left and right, and a limit rib to prevent it from moving forward and backward. The socket connector is fixed in all directions to ensure the stability of the plug-in and ensure the quality of signal transmission.

The above technology can overcome the problems of the Slimline cable components that are easy to shake when plugged in, unstable signal transmission, high manufacturing cost of the insulating rubber, and insufficient structural strength, thus achieving the practical progress of the above advantages.

Please refer to the first to fourth figures, which are three-dimensional to exploded views of the preferred embodiments of the present invention. It can be clearly seen from the figures that the electrical connector 100 of the present invention mainly includes:

A tongue plate portion 1;

A plurality of tongue plate joints 11 are formed on the tongue plate portion 1;

An inner gel body 21 is provided at one end of the tongue plate portion 1;

An outer colloid body 22 is disposed on the outer side of the inner colloid body 21 and forms a two-piece insulating colloid body 2 with the inner colloid body 21;

A clamping colloid 23 is integrally formed at one end of the outer colloid 22 and is held against the surface of the tongue plate portion 1;

A mounting seat 231 is integrally formed on the clamping colloid 23;

A plurality of colloid bonding parts 232 are formed on the clamping colloid 23 and correspond to the tongue plate bonding part 11;

The plurality of positioning members 4 are fixedly mounted on the tongue plate joint 11 and the colloid joint 232. The tongue plate joint 11 and the colloid joint 232 of the present embodiment are perforated, and the positioning members 4 are rivets as an example;

The two limiting structures 5 are integrally formed on both sides of the mounting seat 231. The limiting structure 5 includes an upper stopper 51 above the clamping colloid 23 and a side stopper 52 on one side of the clamping colloid 23;

An insertion slot 53 is formed between the clamping colloid 23 and the limiting structure 5;

At least one limiting rib 54 is integrally formed on one side of the upper stop 51 adjacent to the insertion slot 53, and is used to support and limit the socket connector;

A hollow portion 6 is formed between the clamping colloid 23 and the tongue plate portion 1;

Through the above explanation, we can understand the structure of this technology. According to the corresponding coordination of this structure, we can achieve the advantages of simple process, good structural strength, stable plug-in status, stable signal, etc. The detailed explanation will be given below.

Please refer to the first to seventh figures at the same time, which are the three-dimensional diagrams and the schematic diagram of the insertion limit of the preferred embodiment of the present invention (II). By assembling the above components, it can be clearly seen from the figure that the electrical connector 100 of the present invention is a plug connector of the Slimline specification, so its basic structure includes a tongue plate portion 1, an insulating gel 2, a mounting seat 231, and an elastic element 3, wherein the insulating gel 2 is a two-piece gel composed of an inner gel 21 and an outer gel 22. After the tongue plate portion 1 is welded with the cable, it is first combined with the inner gel 21 to strengthen the combination of the cable on the tongue plate portion 1. The outer plastic body 22 is then wrapped around the outer side of the inner plastic body 21, which is beneficial to the mold opening of the limiting structure 5, thereby reducing the difficulty of the injection process and the manufacturing cost, and the tongue plate portion 1 and the outer plastic body 22 are additionally fixed by the positioning member 4, so that the positioning member 4 penetrates the tongue plate coupling portion 11 on the tongue plate portion 1 and the plastic coupling portion 232 on the clamping plastic body 23 to reduce the shaking of the tongue plate portion 1, wherein the clamping plastic body 23 is the portion of the outer plastic body 22 extending forward, and the mounting seat 231 is formed on the clamping plastic body 23, thereby improving the overall structural strength of the electrical connector 100. In addition, the hollow portion 6 between the clamping colloid 23 and the tongue plate portion 1 is formed by shrinking the volume of the inner colloid 21 when the tongue plate portion 1 is combined with the inner colloid 21, thereby reducing the area of the tongue plate portion 1 being covered. The hollow portion 6 is located in the air, and the dielectric constant (Dielectric Constant) ε _r =1.00053 of air is only slightly higher than the dielectric constant of vacuum. Since the dielectric constant and dissipation factor of the high-frequency substrate will directly affect the speed and quality of the transmitted signal, materials with low dielectric constant and ultra-low dissipation factor are selected to improve signal delay and reduce signal transmission loss, while also meeting the characteristics of high temperature resistance, low noise, and high stability.

As shown in the fifth figure, when the electrical connector 100 is docked with the socket connector 7, the basic operation is the same as that of the previous operation. The tongue plate portion 1 is mainly combined with the socket connector 7, so that the outer shell 71 of the socket connector 7 covers the clamping gel 23, and after insertion, the elastic force of the elastic element 3 is automatically used to naturally fix the buckle protrusion 31 on the elastic element 3 to the clamping portion 72, so as to complete the basic operation of docking the electrical connector 100 with the socket connector 7.

As shown in FIG. 6 and FIG. 7 , the present invention further utilizes the limiting structure 5 to enhance the docking stability of the electrical connector 100 and the socket connector 7. Specifically, the limiting structure 5 forms an insertion slot 53 with the clamping rubber body 23. Therefore, the outer shell 71 wrapped around the clamping rubber body 23 is inserted into the insertion slot 53 of the electrical connector 100 and is covered by the limiting structure 5 from the outside. The limiting structure 5 utilizes the upper stopper 51 to prevent it from swinging up and down, and utilizes the side stopper 52 to prevent it from swinging up and down. To prevent it from shaking left and right, and to prevent it from moving forward and backward by using the limiting ribs 54, the extension direction of the limiting ribs 54 is the same as the insertion direction of the socket connector 7, so that the socket connector 7 can be provided with a linear contact effect of front and back limiting without affecting the insertion action of the socket connector 7. The limiting ribs 54 of this embodiment are implemented with four on each side, thereby fixing the socket connector 7 in all directions, so as to improve the plugging stability and ensure the signal transmission quality.

Please refer to FIG. 8 and FIG. 9 at the same time, which are exploded views and partial cross-sectional views of another preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is similar to the above embodiment, except that the limit structure 5a has a rear stopper 55a connecting the upper stopper 51a and the outer colloid 22a, and has a connection on the mounting seat 231a. The reinforcing wall 2311a of the upper stop 51a is away from the side stop 52a, and a protrusion 521a protruding from the clamping colloid 23a is provided on the side of the side stop 52a away from the outer colloid 22a, and a clamping portion 522a for clamping the socket connector 7a is provided on the side of the protrusion 521a adjacent to the insertion slot 53a.

The rear stopper 55a is connected to the side stopper 52a in addition to the upper stopper 51a and the outer plastic body 22a, and has the effect of strengthening the structural strength of the upper stopper 51a and the side stopper 52a, and has the purpose of preventing the socket connector 7a from being over-inserted. The end of the upper stopper 51a away from the side stopper 52a is further connected to the reinforcing wall 2311a, and the limiting strength of the upper stopper 51a is further strengthened. In addition, the present embodiment has a protruding portion 521a at the front end of the side stopper 52a. The protruding portion 521a is 21a is a protruding clamping rubber 23a and is located on one side of the tongue plate portion 1a, which can not only increase the limiting area on the side of the socket connector 7a, but also an additional locking portion 522a can be set on the inner side of the protruding portion 521a to correspond to the locking groove 73a on the side of the socket connector 7a, thereby assisting the front and rear limiting function of the limiting rib 54a. Therefore, the number of limiting ribs 54a can be reduced as appropriate without affecting the overall function. This embodiment takes the number of limiting ribs 54a as one as an example.

However, the above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention's specification and drawings should be included in the patent scope of the present invention and should be stated.

In summary, the structure of the electrical connector of this invention can truly achieve its effect and purpose when used. Therefore, this invention is truly an invention with excellent practicality. In order to meet the application requirements of invention patents, an application is filed in accordance with the law. I hope that the review committee will approve this invention as soon as possible to protect the inventor's hard work.
