Abstract
The utility model discloses a contact pin and a D-SUB connector female seat. The contact pin comprises a contact pin body; a socket hole is arranged on the contact pin body; a spring sheet is arranged inside the socket hole; the spring sheet is pressed to the lateral wall of the socket hole when an joint plug part is inserted into the socket hole; and simultaneously the joint plug part is provided with inward retaining force. The D-SUB connector female seat can provide strong contact force for the joint plug part after long term use by adopting the contact pin, thereby effectively prolonging the service life of the connector female seat.
Description
Technical field
The utility model relates to field of connectors, relates in particular to a kind of contact pin and has the D-SUB connector female seat of this kind contact pin.
Background technology
The processing technology of traditional D-SUB connector female seat is followed successively by the car contact pin in order, for contact pin fluting, clean contact pin, electroplate contact pin, for contact pin processing reducing, forward the glue in-core insert contact pin, lid back glue core, riveting glue core, the iron-clad of going forward, go up after iron-clad, riveting iron-clad, inspection and packing.In use, the contact pin of connector is that fluting and the reducing by the contact pin of D-SUB connector female seat contacts, and along with to inserting the increase of number of times, the confining force of D-SUB connector female seat will descend, and will directly influence its transmittability to the signal of telecommunication thus; In addition, plug-hole in use appears in the contact pin of D-SUB connector female seat easily, and influence is to inserting effect.
The utility model content
A purpose of the present utility model is to solve the shortcoming that existing connector female seat exists, and a kind of contact pin with high confining force is provided.
The technical scheme that the utility model adopted is: a kind of contact pin, comprise the contact pin body, and described contact pin body has spliced eye; Also comprise the shell fragment that is installed in the spliced eye, described shell fragment will be pressed towards the sidewall of spliced eye when inserting in the spliced eye to plug-in unit, and simultaneously to plug-in unit being provided a kind of inside confining force.
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 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 pawl upwards evenly distributed in the week that connects body.
Another purpose of the present utility model is to provide a kind of D-SUB connector with high confining force.
The technical scheme that the utility model adopted is: a kind of D-SUB connector female seat comprises the glue core and is coated on the outer iron-clad of glue core; Also comprise the described contact pin of claim 1, described contact pin is inserted in the described glue core.
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 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.
The beneficial effects of the utility model are: by for contact pin shell fragment being set, the D-SUB connector female seat that can make contact pin and this contact pin of employing is after long-time the use, also can therefore effectively prolong the useful life of D-SUB 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.
As shown in Figure 1, contact pin 20 described in the utility model comprises contact pin body 23 and shell fragment 22, has spliced eye 21 in the described contact pin body, described shell fragment 22 is installed in the spliced eye 21, shell fragment 22 will be pressed towards the sidewall of spliced eye 21 when inserting in the spliced eye 21 to plug-in unit, and shell fragment 22 is also to plug-in unit being provided a kind of inside confining force simultaneously.For shell fragment 22 can be contacted preferably with the sidewall of spliced eye 21, and for shell fragment 22 can made progress to plug-in unit being provided balanced contact force in week, shell fragment 22 can be designed to claw-like, shown in Fig. 2 and 3, shell fragment 22 comprises the connection body 221 of a ring-type, connect body 221 and upwards extend a plurality of equally distributed shell fragment pawls 223 downwards in week, shell fragment 22 can have four shell fragment pawls 223 or six shell fragment pawls 223 as described, the bottom edge that connects body 221 is the initiating terminal of shell fragment pawl 223, shell fragment 22 is in the raw the time, all shell fragment pawls 223 begin to draw in to the axis of shell fragment 22 gradually to its end from its initiating terminal, therefore, when plug-in unit is inserted spliced eye 21, to enter from connection body 221 inside of shell fragment 22, when plug-in unit is continued to insert downwards, shell fragment pawl 223 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.When shell fragment 22 is installed, can makes it connect body 221 and closely contact with the sidewall of spliced eye.
Shown in Figure 4 and 5, a kind of D-SUB connector female seat comprises glue core 10, iron-clad and above-mentioned contact pin 20.Described glue core 10 comprises riveting preceding glue core together and back glue core; Described iron-clad comprises riveting preceding iron-clad 50 and back iron-clad 40 together equally, and outside the glue core, described back iron-clad 40 was coated on outside the glue core of back before described preceding iron-clad 50 was coated on.
The processing technology of D-SUB connector female seat described in the utility model is followed successively by the car contact pin in order, cleans contact pin, electroplates contact pin, places shell fragment in contact pin, the glue in-core is inserted contact pin, lid back glue core, riveting glue core, the iron-clad of going forward, gone up back iron-clad, riveting iron-clad, inspection and packing forward.This shows, need not contact pin is slotted and reducing processing by adding shell fragment.
Because the effect of shell fragment 22, D-SUB connector female seat be after long-time the use, also can be for plug-in unit be provided strong contact force, and contact pin in use the plug-hole problem can not occur yet, therefore effectively prolonged the useful life of D-SUB connector female seat.
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.
