Abstract

The utility model discloses a novel RJ-45 socket comprising a pin seat and a PIN pin connected to the pin seat. The PIN pin comprises an elastic part. The pin seat comprises a body. A plurality of first grooves are uniformly arranged on the upper end of the body at intervals. The elastic part of the PIN pin is arranged above the first grooves in an inclined mode. A sink preventing baffle sheet is arranged in each first groove in a mode of extending upwardly from the bottom of the groove. The height of each sink preventing baffle sheet is higher than each first groove. The top ends of the sink preventing baffle sheets are arranged below the elastic part of the PIN pin. When a crystal plug is inserted, a limit position for the elastic part of the PIN pin to go downward is just the top end of the sink preventing baffle sheets, so that a part of the pressure applied to the elastic part of the PIN pin is absorbed by the sink preventing baffle sheets, and accordingly loss of elasticity due to usage fatigue will not easily occur; in addition, even if after the connector is inserted and connected for a plurality of times, the elastic part of the PIN pin is not elastic enough to spring up, the lowest position of the elastic part of the PIN pin is also the top end of the sink preventing baffle sheets, and accordingly, after the crystal plug is inserted into the RJ-45 socket, the crystal head can still be in contact with the PIN pin, and contact failures will not occur.

Description

A kind of novel Registered Jack-45

Technical field

The utility model relates to a kind of communication interface, relates in particular to a kind of Registered Jack-45.

Background technology

As shown in Figure 1, known Registered Jack-45 generally comprises a shell 10, with the fixing needle stand 20 of shell 10, be connected in the PIN pin 30 of needle stand 20, after crystal head 40 is pegged graft with Registered Jack-45, PIN pin 30 is squeezed down and is hanging shape, so, after crystal head is pegged graft for more than 40 time, thereby can cause PIN pin 30 to use tired cannot normally upspringing, cause loose contact.

Utility model content

The purpose of this utility model is to provide a kind of novel Registered Jack-45, and it can prevent that PIN pin from causing the situation of loose contact because using fatigue normally to upspring.

For achieving the above object, the technical scheme that the utility model adopts is:

A kind of novel Registered Jack-45, comprise a shell, with the fixing needle stand of shell and be connected in the PIN pin of needle stand, described PIN pin comprises the bottom being integrally formed, the pars intermedia of elastic portion and connection bottom and elastic portion, described needle stand comprises a body, described body upper end is evenly arranged at intervals with multiple the first grooves, the elastic portion of described PIN pin is obliquely installed in the top of needle stand body the first groove, described each first groove up extends and is provided with the anti-catch that sink from trench bottom, the height of the described anti-catch that sink is higher than the first groove, described anti-top of sinking catch is arranged at the below of PIN pin elastic portion.

Corresponding the first groove, described needle stand body lower end is evenly arranged at intervals with multiple the second grooves, described needle stand also comprise one from body rear end the joint portion toward downward-extension, corresponding the second groove, described joint portion is provided with through hole, described through hole communicates with the second groove, and the bottom of described PIN pin is arranged at needle stand the second groove and through the joint portion through hole communicating, pars intermedia is arranged at needle stand body front end.

Described needle stand also comprises the upper extension up extending from body rear end.

The beneficial effects of the utility model are: after crystal head and the utility model Registered Jack-45 are pegged graft, PIN pin elastic portion contacts with crystal head and is pressed down by past, until PIN pin elastic portion touches the anti-catch that sink, that is to say, there is the anti-catch that sink PIN pin elastic portion below as support, after crystal head inserts, PIN pin elastic portion extreme position is down just the top of the anti-catch that sink, so, the pressure part that PIN pin elastic portion is subject to is absorbed by the anti-catch that sink, thereby PIN pin is not easy because using fatigue to follow the string, in addition, even if under permanent use, after crystal head is repeatedly pegged graft, PIN pin elastic portion elasticity deficiency cannot be upspring, even but in this state, the extreme lower position of PIN pin elastic portion is also the top of the anti-catch that sink, thereby crystal head inserts after Registered Jack-45, still can contact with PIN pin, can loose contact, that is to say, the utility model Registered Jack-45 has fundamentally guaranteed the contact reliability of PIN pin, improved the useful life of PIN pin simultaneously.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 2,3, the utility model Registered Jack-45 comprise a shell 1, with the fixing needle stand 2 of shell 1 and be connected in the PIN pin 3 of needle stand 2.

As shown in Fig. 3,4,5, described needle stand 2 comprises a body 21 and the joint portion 22 toward downward-extension from body 21 rear ends, described body 21 upper ends are evenly arranged at intervals with multiple the first grooves 211, corresponding the first groove 211, body 21 lower ends are evenly arranged at intervals with multiple the second grooves 212, described each first groove 211 up extends and is provided with the anti-catch 23 that sink from trench bottom, the height of the described anti-catch 23 that sink is higher than the first groove 211, and anti-top of sinking catch 23 is exposed to outside the top of the first groove 211; Corresponding the second groove 212, described joint portion 22 is also provided with through hole 221, and described through hole 221 communicates with the second groove 212.In addition, needle stand 2 also comprises the upper extension 24 up extending from body 21 rear ends.Described needle stand 2 sink catch 23 except anti-, and other are known technology.

Described PIN pin 3 is known technology, comprises bottom 31, the elastic portion 32 being integrally formed and the pars intermedia 33 that connects bottom 31 and elastic portion 32, and needle stand 2 can be known technology with the assembling mode of PIN pin 3.

In the present embodiment, described shell 1, shell 1 are known technology with the assembling mode of needle stand 2, so do not repeat at this.

After needle stand 2 is assembled with PIN pin 3, the bottom 31 of described PIN pin 3 is arranged at needle stand 2 second grooves 212 and passes joint portion 22 through holes 221 that communicate, pars intermedia 33 is arranged at needle stand 2 body 21 front ends, the elastic portion 32 of described PIN pin 3 is obliquely installed in the top of body 21 first grooves 211, and described anti-top of sinking catch 23 is arranged at the below of PIN pin elastic portion 32.

As shown in Figure 6, after crystal head 40 is pegged graft with the utility model Registered Jack-45, PIN pin elastic portion 32 contacts with crystal head 40 and is pressed down by past, until PIN pin elastic portion 32 touches the anti-catch 23 that sink, that is to say, there is the anti-catch 23 that sink PIN pin elastic portion 32 belows as supporting, after crystal head 40 inserts, PIN pin elastic portion 32 extreme position is down just the top of the anti-catch 23 that sink, so, the pressure part that PIN pin elastic portion 32 is subject to is absorbed by the anti-catch 23 that sink, thereby PIN pin 3 is not easy because using fatigue to follow the string, in addition, even if under permanent use, after crystal head is pegged graft for more than 40 time, PIN pin elastic portion 32 elasticity deficiencies cannot be upspring, even but in this state, the extreme lower position of PIN pin elastic portion 32 is also the top of the anti-catch 23 that sink, thereby crystal head 40 inserts after Registered Jack-45, still can contact with PIN pin elastic portion 32, can loose contact.That is to say, the utility model Registered Jack-45 has fundamentally guaranteed the contact reliability of PIN pin 3, has improved the useful life of PIN pin 3 simultaneously.

The utility model needle stand 2 can also be adapted to the similar structures such as RJ11.
