A connector

Abstract

The present invention discloses a connector provided with a partition spring arm, comprising a molded part, an upper row of terminals, a lower row of terminals and a metal middle partition, wherein the molded part wraps at least a portion of the metal middle partition in at least a portion of the metal middle partition; the metal middle partition comprises an elastic arm, which passes through a vertical wall located at the molded part and extends obliquely. When the line-end connector is plugged into the board-end connector, the shell of the line-end connector compresses the elastic arm and forms a grounding connection with the elastic arm and the metal middle partition in the board-end connector. When the line-end connector and the board-end connector are plugged into each other and the fitting tolerance is loosened due to external influences, the shell of the line-end connector can still form a stable connection with the metal middle partition due to the elasticity of the elastic arm. And the shell of another connector is connected through the elastic arm to construct another grounding loop, so that the grounding effect is better.

Description

Technical Field

[0001] The invention relates to the field of connectors, in particular to a connector provided with elastic arms. Background Art

[0002] The connector usually consists of a male end and a female end, and the connection is achieved by plugging the male end and the female end. As the transmission frequency requirements of existing high-speed cables have been increasing, the crosstalk changes generated by high-speed cables need to be introduced into the metal partition, that is, to achieve better anti-EMI effect through the grounding of the metal partition. However, the existing metal partitions are all set inside the product. Generally, the metal partition is connected to the shell at the female connector, and the male end is connected to the female connector and then connected to the male connector through the shell to achieve grounding. This shell grounding connection method is very easy to affect the grounding effect due to unstable tolerance during plugging, thereby affecting the anti-EMI effect. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a board-end connector with an elastic arm arranged on a metal partition plate, and stable grounding of the board-end connector and the line-end connector is achieved by squeezing and deforming the elastic arm when the board-end connector and the line-end connector are plugged in.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a connector, including a molded part, an upper row of terminals, a lower row of terminals and a metal middle partition, wherein the molded part wraps at least a portion of the metal middle partition therein, and the metal middle partition includes at least one elastic arm, which passes through the vertical wall of the molded part and extends obliquely.

[0006] As a further improvement of the above technical solution, a blocking plate of the metal intermediate partition is located between the upper terminal slot group and the lower terminal slot group.

[0007] As a further improvement of the above technical solution, the blocking plate includes a plurality of perforations.

[0008] As a further improvement of the above technical solution, a connecting arm is extended outward from the left and right ends of the blocking plate respectively, and the other end of the connecting arm relative to the blocking plate is connected to the corresponding elastic arm.

[0013] The beneficial effect is as follows: a metal middle partition is provided on the connector plug of the present invention, and an elastic arm is provided on the metal middle partition. When the line-end connector is plugged into the board-end connector, the shell of the line-end connector compresses the elastic arm and forms a ground connection with the elastic arm and the metal middle partition in the board-end connector. When the line-end connector and the board-end connector are plugged into each other and the fitting tolerance is loosened due to external influences, the shell of the line-end connector can still form a stable connection with the metal middle partition due to the elasticity of the elastic arm.

[0023] Reference Figure 2 , Figure 3 A connector provided with a partition spring arm 41 includes a molded part 1, an upper row of terminals 2, a lower row of terminals 3 and a metal middle partition 4.

[0024] Reference Figure 4 Specifically, the molded part 1 is an integral structure formed by molding, which mainly supports and isolates various structures inside the connector. For the convenience of description, the movement direction of the connector when plugged in is set to the front. Or, taking this example as a board end / female end connector, the so-called front refers to the direction facing the line end / male end connector.

[0025] The molded part 1 includes a base 11 and a tongue 12. The base 11 and the tongue 12 are one-piece formed molded parts. The tongue 12 extends outward from a front surface of the base 11. The tongue 12 includes an upper terminal slot group and a lower terminal slot group. In this example, the upper terminal slot group and the lower terminal slot group are respectively formed on the upper surface and the lower surface of the tongue 12, suitable for terminal insertion. The upper terminal slot group includes a plurality of terminal slots connected to the channels running through the front and rear sides of the base 11. The terminal slots in the upper terminal slot group are located on the same horizontal surface and are parallel to each other, and the front ends of the terminal slots are uncovered and can be connected to the external space. In addition, elastic arm slots 13 are provided on both sides of the base 11.

[0026] Reference Figure 4 , Figure 5 On the other hand, the shape of the end face at the front end of the tongue 12 is an inverted U-shape, corresponding to the shape of the end face of the male connector. On the other hand, a horizontal empty slot is provided between the upper terminal slot group and the lower terminal slot of the tongue 12. The range of the horizontal empty slot is larger than the outer contour of the upper terminal slot group and the lower terminal slot, and is suitable for a metal plate to be buried therein to effectively block the space between the upper terminal slot group and the lower terminal slot group. In this example, the horizontal empty slot is isolated from the upper terminal slot group and the lower terminal slot group and is not connected. In another example, the upper terminal slot group and the lower terminal slot group can be connected to the horizontal empty slot at the same time to allow the components in the upper terminal slot group and the lower terminal slot group to contact and conduct with the components in the horizontal empty slot respectively.

[0027] like Figure 5 As shown, the upper row of terminals 2 and the lower row of terminals 3 respectively include a plurality of metal terminals of different lengths and different uses, such as copper terminals. Figure 2 As shown, the metal terminal with the end located closer to the front end (longer) is used for grounding, and the terminals arranged in pairs and with the end located closer to the rear end (shorter) are used as differential pairs to transmit signals.

[0028] like Figure 5 As shown, the metal partition 4 is formed by stamping / cutting an integral metal sheet, and includes an elastic arm 41 and a baffle 42. The baffle 42 is used to absorb and prevent electromagnetic waves from passing through, and the absorbed electromagnetic wave energy is usually conducted away in a noise manner through a ground terminal directly or indirectly connected to the metal partition 4. The so-called ground terminal includes, but is not limited to, the metal shell 5 of the board-end connector, the circuit board where the board-end connector is located, or the metal shell of the line-end connector. Figure 5The blocking plate 42 is generally in an inverted U-shape with an opening facing downward (for example, facing the circuit board), that is, the blocking plate is generally a U-shaped three-dimensional columnar structure and the three-dimensional columnar structure is formed by being bent. Connecting arms 43 extend outward from the left and right ends of the rear end portion of the inverted U-shaped blocking plate 42, and the ends of the connecting arms 43 are respectively connected to an elastic arm 41. When the blocking plate 42 is placed horizontally, the two elastic arms 41 extend forward and in the same or opposite up and down directions. In addition, in this example, a plurality of through holes are provided on the blocking plate 42 that penetrate the upper and lower surfaces, one of the functions of which is to allow the rubber to enter to improve its fixing effect.

[0029] Reference Figure 1 The metal shell 5 is a hollow ring structure with a rectangular outer contour, suitable for the molded part 1 to be fixed therein. The metal shell 5 can play a protective role on the outside, further improving the safety and stability of the connector as a whole. The metal shell 5 includes a plurality of conductive pins for electrically connecting to the circuit board. The metal shell 5 can directly contact and be electrically connected to the metal middle partition 4 to serve as a part of the grounding terminal.

[0030] In this example, the molded part 1 is directly formed outside the metal partition 4 by injection molding, that is, the two are not plug-in combined, so that the gap between the metal partition 4 and the molded part 1 can be reduced to ensure the close combination of the two. However, after appropriate structural adjustment, the metal partition 4 can also be changed to a plug-in type, and the present invention does not impose more restrictions on this. In this example, the upper row of terminals 2 and the lower row of terminals 3 are plug-in type, but when necessary, they can also be embedded in the forming mold of the molded part 1 and fixed by rubber material in accordance with the manufacturing method of the metal partition 4.

[0031] After the assembly, the molded part wraps at least a portion of the metal middle partition 4 in at least a portion of the metal middle partition 4. At the same time, a portion of the metal middle partition 4 is electrically connected to the metal shell 5 by direct contact or a connector, whereby the noise of the metal middle partition 4 can be guided to the ground connection pad of the circuit board through the pins of the metal shell 5 to form a ground loop.

[0032] On the other hand, the elastic arm 41 passes through the vertical wall located at the molded part 1 and extends forward obliquely. The elastic arm 41 extending from the metal partition of the female connector is directly in contact with the outer shell of the male / line connector, thereby forming another grounding loop, improving the grounding effect, and ensuring efficient and stable signal transmission. The elastic arm 41 is elastic. When the male connector and the female connector are connected, the outer shell of the male connector and the elastic arm 41 form an elastic contact. This elastic contact makes it possible for the elastic arm 41 to still form a stable contact with the outer shell of the male connector after rebounding when the plug-in between the male connector and the female connector becomes loose, thereby ensuring the stability of the electrical connection. This plug-in structure for ensuring the stability of the connection during plug-in can achieve the effect of stable electrical connection when plugged in anywhere. The elastic arm 41 passes through the vertical walls on the left and right sides of the tongue 12.

[0033] The base 11 of the molded part 1 is longer than the tongue 12, so the two sides of the front surface of the base 11 will directly dock with the connector, and a stable connection effect can be achieved by setting an elastic arm 41 on either side. Generally, elastic arms 41 are set on both sides, so that the force during insertion is more stable.

[0034] The lower row of terminals 3 are exposed from the openings of the lower terminal slot group. When component A is exposed from component B as stated in the specification and claims of the present invention, it is defined as component A not being completely covered by component B, provided that there is no conflict with the original recorded content. The arrangement between the upper row of terminals 2 and the lower row of terminals 3 is similar and will not be described in detail. The tongue 12 of the molded part 1 arranged in this way can well support the upper terminal and the lower row of terminals 3 respectively, and prevent adjacent terminals from deforming and contacting due to external force. Moreover, the tongue 12 of the molded part 1 arranged between the upper row of terminals 2 and the lower row of terminals 3 will not affect the plugging of the terminals, but will improve the rigidity during plugging, and prevent the terminals from being squeezed and deformed due to unstable forces received during plugging.

[0035] The elastic arm 4 passes through the vertical wall on the left or right side of the tongue 12. The base 11 of the molded part 1 is longer than the tongue 12, so the two sides of the front surface of the base 11 will directly dock with the plug-in component, and the elastic wall can be set on either side to achieve a stable connection effect. Generally, the elastic wall is set on both sides, so that the force during plugging is more stable.

[0036] As an implementation method of the present scheme, most of the metal middle partition 4 except the elastic arm 41 is located inside the molded part 1, and only a small part is exposed from the molded part 1. The molded part 1 is a structure integrally formed on the periphery of the metal middle partition 4. A part of the metal middle partition 4 is located in the tongue 12 structure of the molded part 1, and the length of the base 11 of the molded part 1 is greater than the length of the tongue 12. Therefore, two extension sections extend from both sides of the metal middle partition 4, so that the elastic arms 41 located at both ends of the metal middle partition 4 can extend out of the molded part 1 at both sides in front of the base 11. The setting of this position can not only realize that the elastic arm 41 can first contact the connector when the connector is connected, but also the position of the elastic arm 41 will not extend forward beyond the distance of the tongue 12 of the molded part 1, and will not increase the overall size of the connector. Since a portion of the metal intermediate partition 4 is located in the equipment structure of the molded part 1, and the upper and lower surfaces of the tongue 12 structure are respectively provided with an upper terminal slot group and a lower terminal slot group, a portion of the metal intermediate partition 4 is located between the upper terminal slot group and the lower terminal slot group.

[0037] As one of the implementation methods of this scheme, the metal middle partition 4 is integrally formed. The integrally formed structure can ensure the stability of the overall structure of the metal middle partition 4. The elastic arm 41 extends away from the molded part 1 at an oblique angle to the vertical wall of the molded part 1. The inclined extension direction provides sufficient buffer space for the deformation of the elastic arm 41. The molded part 1 is also provided with an inwardly recessed elastic arm groove 13 relative to the elastic arm 41. The elastic arm groove 13 is used to accommodate the elastic arm 41 after being compressed and deformed. The setting of the elastic arm 41 groove can further increase the buffer space of the elastic arm 41. When plugging, the elastic arm 41 is pressed into the elastic arm groove 13. The two edges of the plug-in can be in contact or inserted a deeper distance. The specific proximity between the two plug-in main bodies can increase the overall stability of the two after plugging; and another grounding loop can be selectively added to ensure the grounding effect.

[0038] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
