Abstract

The utility model discloses a connector female seat which comprises an insulating body. The insulating body is internally provided with a contact piece used for transferring electric signals. The connector female seat is characterized in that a shrapnel which can press an inserting piece toward the side wall of a spliced eye when the inserting piece is inserted is installed in the spliced eye of the contact piece. Due to the action of the shrapnel, when being used for a long time, the connector female seat can also supply strong contact force to the inserting piece, thereby efficiently prolonging the service life of the connector female seat.

Description

A kind of connector female seat

Technical field

The utility model relates to a kind of electric connector field, relates in particular to a kind of connector female seat.

Background technology

The contact of existing connector female seat is generally car spare, and takes the groove milling closing in to form spliced eye, and spliced eye is used for and plug-in unit is contacted.Along with contact and between the plug-in unit to inserting the increase of number of times, the confining force of connector female seat will descend, and will directly influence the transmittability of connector female seat to the signal of telecommunication thus.

The utility model content

The purpose of this utility model is to solve the shortcoming that existing connector female seat exists, and a kind of connector female seat with high confining force is provided.

The technical scheme that the utility model adopted is: a kind of connector female seat, comprise insulating body, and be provided with the contact that is used for transmission of electric signals in the described insulating body; The shell fragment that can be pressed to the sidewall of spliced eye when plug-in unit is inserted is installed in the spliced eye of described contact.

Preferably, described shell fragment comprises the connection body of a ring-type, and described connection body closely is connected with the sidewall of spliced eye; Described connection body upwards extends a plurality of equally distributed shell fragment pawls downwards in week, the bottom edge of described connection body is the initiating terminal of described shell fragment pawl, described shell fragment is in the raw the time, and all shell fragment pawls begin to draw in to the axis of described shell fragment gradually to its end from its initiating terminal.

Preferably, described shell fragment comprises four shell fragment pawls.

Preferably, the end face of the connection body of described shell fragment is concordant with the end face of described contact.

The beneficial effects of the utility model are: by for contact is provided with shell fragment, can make the connector female seat after long-time the use, also can therefore effectively prolong the useful life of connector female seat for plug-in unit being provided with strong contact force.

Embodiment

Now in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.

Shown in Fig. 1,3 and 4, the connector female seat comprises insulating body 10, is provided with the installing hole 11 that is used to install contact 20 in the insulating body 10.The utility model is an example with 5P connector female seat, is provided with five installing holes 11 in the insulating body 10, and the distributing position of installing hole 11 is determined according to the standard of 5P connector.Contact 20 is installed in the installing hole 11.As shown in Figure 4, the top of contact 20 has spliced eye 21, and the bottom has chamfered edge hole 23, and between spliced eye 21 and chamfered edge hole 23 is entity section 22.

Shown in Fig. 2 and 4, in the spliced eye 21 of contact 20 shell fragment 30 is installed, shell fragment 30 will be pressed towards the sidewall of spliced eye 21 when inserting in the spliced eye 21 to plug-in unit, and shell fragment 30 is also to plug-in unit being provided a kind of inside confining force simultaneously.For shell fragment 30 can be contacted preferably with the sidewall of spliced eye 21, and for shell fragment 30 can made progress to plug-in unit being provided balanced contact force in week, shell fragment 30 can be designed to claw-like, as shown in Figure 5, shell fragment 30 comprises the connection body 31 of a ring-type, connect body 31 and upwards extend a plurality of equally distributed shell fragment pawls 32 downwards in week, have four shell fragment pawls 32 in the present embodiment, can certainly have three or six shell fragment pawls 32, the bottom edge that connects body 31 is the initiating terminal of shell fragment pawl 32, shell fragment 30 is in the raw the time, all shell fragment pawls 32 begin to draw in to the axis of shell fragment 32 gradually to its end from its initiating terminal, therefore, when plug-in unit is inserted spliced eye 21, will enter from connection body 31 inside of shell fragment 30, when plug-in unit is continued to insert downwards, four shell fragment pawls 32 will be strutted and be contacted with the sidewall of spliced eye 21, and simultaneously for plug-in unit being provided radially inner contact force.Make at installation shell fragment 30, can make it connect body 31 and closely contact, and make the end face that connects body 31 concordant with the end face of described contact 20 with the sidewall of spliced eye.

Because therefore the effect of shell fragment 30, connector female seat after long-time the use, also can effectively prolong the useful life of connector female seat for plug-in unit being provided with strong contact force.

Being the utility model preferred embodiment only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
