Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a short connector structure. Background Technology

[0002] In the current field of electronic and electrical connection technology, connectors, as key components for signal transmission and power conduction, are generally designed to ensure the reliability, durability, and safety of the connection. Traditional connectors, based on relevant industry standards, typically employ a relatively long shell structure in their structural design to ensure sufficient mating depth and contact length between the pins and sockets, thereby meeting the basic requirements for mechanical strength, mating life, and electrical performance.

[0003] However, with the increasing trend of modern electronic products towards miniaturization, thinness, and high integration, the drawbacks of traditional connectors, such as large footprint, heavy weight, and high material costs, are becoming increasingly prominent. This is especially true in thin, small, or compact terminal products, where traditional connector structures are no longer sufficient to meet their requirements. Therefore, effectively shortening the overall length of connectors while ensuring connection performance has become a key challenge. Utility Model Content

[0004] The purpose of this invention is to provide a short connector structure that, through structural improvements, shortens the connector length while ensuring its connection performance.

[0005] The technical solution adopted by the short connector structure disclosed in this utility model is: A short connector structure includes a housing, a front insulator, a rear insulator, and a terminal group. The front and rear insulators are both enclosed within the housing. The front insulator has an insertion cavity and several slots at one end near the rear insulator. The insertion cavity extends through the front insulator. The slots are respectively located at the upper and lower ends of the insertion cavity and communicate with the insertion cavity. One end of the terminal group extends through the rear insulator and out of one end of the housing. The other end of the terminal group is inserted into the slot. The rear insulator is fixed to one side of the front insulator, forming a stop surface of the insertion cavity.

[0006] As a preferred embodiment, the rear insulator includes an upper half and a lower half, and the terminal group includes a plurality of contact terminals, which are symmetrically arranged on the upper half and the lower half.

[0007] As a preferred embodiment, the upper body and the lower body are connected by a hook, the hook including a connecting part and two clamping arms. The connecting part is fixed between the upper body and the lower body, the clamping arms are disposed on both sides of the connecting part, and the insertion cavity is formed by grooves on both sides. The clamping arms are inserted into the grooves and extend into the insertion cavity.

[0008] As a preferred embodiment, the connecting part is provided with lugs on both sides, the lugs are interference-fitted with the inner wall of the housing, and the edges of the lugs are chamfered.

[0009] As a preferred embodiment, the upper body and the lower body are provided with positioning posts and positioning grooves on their respective sides, the positioning posts and positioning grooves are respectively arranged opposite to each other, the connecting part is opened in the through hole corresponding to the positioning post, and the positioning post passes through the through hole and is inserted into the positioning groove.

[0010] As a preferred embodiment, the front insulator is provided with a locking block on the side near the rear insulator, the locking block is connected to the surfaces of the upper and lower ends of the insertion cavity, and the rear insulator is provided with a locking groove corresponding to the locking block, the locking block being embedded in the locking groove.

[0011] As a preferred embodiment, both the upper and lower surfaces of the rear insulator are provided with limiting blocks, and the tail of the housing is provided with a corresponding limiting groove, wherein the limiting blocks are inserted into the slots.

[0012] As a preferred embodiment, both the upper and lower surfaces of the rear insulator are provided with raised ribs, and the raised ribs are interference-fitted with the inner wall of the housing.

[0013] As a preferred embodiment, one end of the housing protrudes beyond one end of the front insulator.

[0014] As a preferred embodiment, the end of the contact terminal extending out of the housing is vertically positioned towards the outer layer.

[0015] The beneficial effects of the short connector structure disclosed in this utility model are as follows: by fixing the terminal group to the rear insulator, and opening the front insulator in the insertion cavity and slot, the terminal group is then inserted into the slot to achieve contact and conduction. This effectively shortens the length of the front insulator, making it only serve as a guide and limiter for the terminal group during connector insertion. The rear insulator is used to form a stop surface for the insertion cavity, so that the rear insulator has both fixing and stopping effects. While ensuring sufficient insertion depth, it reduces the structure such as the stop step of the insulator in traditional connectors. Furthermore, by dividing the terminal group into two sections, fixing and inserting, the redundant intermediate transition support structure is eliminated, the terminal path becomes more straight, and the length of unnecessary structures is shortened, thereby reducing the overall length of the connector.

[0020] Figure 5 This is a schematic diagram of another embodiment of the short connector structure of this utility model. Detailed Implementation

[0021] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figures 1 to 3 A short connector structure includes a housing 10, a front insulator 20, a rear insulator 30, and a terminal group. The front insulator 20 and the rear insulator 30 are both enclosed within the housing 10. The front insulator 20 has an insertion cavity 21 and several slots 22 at one end near the rear insulator 30. The insertion cavity 21 passes through the front insulator 20. The slots 22 are respectively opened at the upper and lower ends of the insertion cavity 21 and are connected to the insertion cavity 21. One end of the terminal group passes through the rear insulator 30 and extends out of one end of the housing 10. The other end of the terminal group is inserted into the slot 22. The rear insulator 30 is fixed to one side of the front insulator 20 to form a stop surface of the insertion cavity 21.

[0022] By fixing the terminal group to the rear insulator 30, and having the front insulator 20 formed in the insertion cavity 21 and slot 22, the terminal group is then inserted into the slot 22 to achieve contact and conductivity. This effectively shortens the length of the front insulator 20, making it only serve as a guide and limiter for the terminal group during connector insertion. The rear insulator 30 forms a stop surface in the insertion cavity 21, thus achieving both fixing and stopping effects. While ensuring sufficient insertion depth, this reduces the need for stop steps and other structures found in traditional connectors. Furthermore, by dividing the terminal group into two sections—fixing and insertion—the lengthy intermediate transition support structure is eliminated, making the terminal path more linear and shortening unnecessary structures, thereby reducing the overall length of the connector. In the above scheme, the rear insulator 30 includes an upper half 31 and a lower body 32. The terminal group includes a plurality of contact terminals 40, which are symmetrically arranged on the upper half 31 and the lower body 32. There is a hook 33 between the upper half 31 and the lower body 32. The hook 33 includes a connecting part and two clamping arms. The connecting part is fixed between the upper half 31 and the lower body 32. The clamping arms are arranged on both sides of the connecting part. The insertion cavity 21 has grooves 24 on both sides. The clamping arms are inserted into the grooves 24 and extend into the insertion cavity 21.

[0023] The upper half 31, the hook 33 and the lower body 32 form a sandwich structure, thereby shortening the length space required by the hook 33. Therefore, while satisfying the assembly of the hook 33, the length of the rear insulator 30 is shortened. At the same time, the upper half 31 and the lower body 32 are used to insulate and separate the contact terminal 40 from the hook 33. The clamping arm of the hook 33 extends into the insertion cavity 21 of the front insulator 20 to lock other inserted connectors, thereby improving the strength of the connector. The sliding grooves 24 on both sides of the insertion cavity 21 serve as a clearance and also provide space for the deformation displacement generated by the clamping arm during clamping.

[0024] Lugs 331 are provided on both sides of the connecting part. The lugs 331 are interference fit with the inner wall of the housing 10. The lugs 331 can make contact and conduction with the hook 33 and the housing 10 to achieve the grounding effect. The edges of the lugs 331 are chamfered. Since the side of the housing 10 is a curved structure, the chamfered structure can make the center of the surface of the lugs 331 fit better with the housing 10, so as to achieve more stable contact and fixation. The housing 10 and the lugs 331 can also be welded and fixed by laser welding to achieve the purpose of conduction.

[0025] Please refer to Figure 4 The upper half 31 and the lower body 32 are provided with positioning posts 321 and positioning grooves 322 on one side close to each other. The positioning posts 321 and positioning grooves 322 are respectively arranged opposite to each other. The connecting part is opened in the through hole corresponding to the positioning post 321. The positioning post 321 passes through the through hole and is inserted into the positioning groove 322. The structure of the positioning post 321 and the positioning groove 322 makes the upper half 31 and the lower body 32 have better stability after assembly, and also plays a better role in assembly alignment.

[0026] The front insulator 20 is provided with a locking block 23 on the side near the rear insulator 30. The locking block 23 connects the upper and lower surfaces of the insertion cavity 21, and the rear insulator 30 is provided with a locking groove 34 corresponding to the locking block 23. The locking block 23 is embedded in the locking groove 34, which facilitates the alignment and calibration of the front insulator 20 and the rear insulator 30 during assembly.

[0027] Limiting blocks 35 are provided on both the upper and lower surfaces of the rear insulator 30, and a corresponding limiting groove 11 is provided at the tail of the housing 10. The limiting blocks 35 are inserted into the slots 34, which facilitates the alignment and limiting of the housing 10 and the rear insulator 30 during assembly. At the same time, ribs 36 are provided on both the upper and lower surfaces of the rear insulator 30. The ribs 36 are interference-fitted with the inner wall of the housing 10, which improves the connection stability between the housing 10 and the rear insulator 30.

[0028] One end of the housing 10 protrudes beyond one end of the front insulator 20, thereby creating a clearance effect by utilizing the height difference between the housing 10 and the front insulator 20, resulting in a better insertion effect. The housing 10 can also be used to protect the front insulator 20.

[0029] Please refer to Figure 5 Furthermore, depending on the different application scenarios of the connector, the end of the contact terminal 40 extending out of the housing 10 can be set vertically towards the outer layer, so that the connector can be set upright during installation and use, thus meeting different assembly requirements.

[0030] This utility model provides a short connector structure. By fixing the terminal group to the rear insulator and opening the front insulator in the insertion cavity and slot, the terminal group is inserted into the slot to achieve contact and conduction. This effectively shortens the length of the front insulator, making it only serve as a guide and limiter for the terminal group during connector insertion. The rear insulator forms a stop surface for the insertion cavity, allowing it to serve both fixing and stopping functions. While ensuring sufficient insertion depth, it reduces the stop steps and other structures of the insulator in traditional connectors. Furthermore, by dividing the terminal group into two sections—fixing and insertion—it eliminates the redundant intermediate transition support structure, making the terminal path more linear and shortening the length of unnecessary structures, thereby reducing the overall length of the connector.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
