Abstract

The utility model relates to an electric signal connector, especially an insulator for an electric signal connector socket. The insulator is composed by convexly and concavely engaging the an upper piece with a lower piece, wherein the upper piece is opposite to socket pores of the lower piece, the socket pore interface of the upper piece is manufactured into a guidance interface of horn shape, and diameter of the socket pore is prepared into size for engaging with outer diameter of the socket body. On basis of the insulator in prior art, the insulator is slit into the upper piece and the lower piece, each implementing different functions. The upper piece is used for guiding direction of the inserting needle and correcting position of the socket body, the lower piece is used for mounting and dismounting of the socket body. Consequently, swing phenomenon of the socket body in prior art is avoided, stable electric connection between the inserting needle and the socket body is guaranteed, not only application function of the catching/inserting tool is kept, but also facilitate precision of the inserting operation.

Description

The insulating part of electric signal connector socket

Technical field

The utility model relates to electric signal connector, and the particularly improvement of electric signal connector socket insulating part is widely used in signal of telecommunication control connections such as rail locomotive, industrial equipment.

Background technology

In the electric connector of existing Control on Communication, because of the needs that reality is used, it is less that the plug-in unit size of connector is done, and particularly contact pin is smaller or equal to φ 1.6mm, and the more specification of core number.Because size is less, just be not easy inserting if these plug-in unit location are inaccurate.Existing socket insulating part 2 and socket 3 shapes are respectively as Fig. 5, shown in Figure 6, and socket 3 middle parts are cut into skirt lobe 31, and the skirt lobe lower edge of socket just cooperates with the necking down position 22 at insulating part 2 middle parts with position 32 between the fin 33.The socket insulating part is made into integration, its stomidium 21 is less right angle enlarging, guide function is poor when plug-in unit is installed, be not easy to insert accurate, and consider the use of getting the instrument of inserting, it is bigger that endoporus is done, there are upper and lower clearance D, H between the outer wall of socket insulating part 2 hole walls and socket 3 and the afterbody 34, cause plug-in unit to swing, and the existence of swing can produce some lock pin to aim at when patching, some lock pin misalignment, make plug-in unit to inserting difficulty more, be easy to generate the loose contact phenomenon again and influence signal transmission quality.

The utility model content

The utility model is exactly the insulating part that the electric signal connector socket that a kind of plug-in unit do not have swing is provided at above-mentioned technical problem, patches firmly, accurately, makes the serviceability that patches of product obviously improve, and has reduced failure rate.

The insulating part of the utility model electric signal connector socket, it is characterized in that described insulating part by last and the concavo-convex cooperation of following part butt joint form, the socket aperture of last part and following part over against, the socket aperture port of last part is made tubaeform targeting port.

The size that cooperates with the socket external diameter is made in described aperture of going up the socket aperture of part.

The socket aperture middle part of described part down is shaped on necking part, and the size that leaves the gap with the socket external diameter is made in the aperture of the socket aperture of necking part top, and stepped hole is made in the bottom of the socket aperture of necking part below, and its Kong Chengyu socket afterbody external diameter cooperates.

The utility model socket insulating part is on original basis, insulating part be divided into two by last and following part form, two parts are realized difference in functionality respectively, last part is responsible for the guiding of contact pin and is corrected the socket position, following part is responsible for the demolition, installation of socket, has avoided the dancing of original socket, has guaranteed contact pin, the good firm electric contact of socket, both kept getting the function of use of the instrument of inserting, it is accurately convenient to make again inserting operation.

Embodiment

With reference to Fig. 1-Fig. 3, socket aperture port one 2 chamferings of part 1 upper end are made tubaeform targeting port on the insulating part of the utility model electric signal connector socket, its effect is when contact pin departs from the position 4 of socket aperture 11, the tubaeform conical surface is from 5 guiding over against the position of trend socket aperture 11, avoid some contact pin to aim at some contact pin misalignment phenomenon.It is concavo-convex 13 that make last part 1 lower end, and the size that cooperates with socket 3 external diameters shown in Figure 6 is made in the aperture of its socket aperture 11, and socket 3 tops are axially limited; The shape of following part 2 and existing socket insulating part are basic identical, and different is the contraction in length of its top socket aperture 26, and the length of shortening is joined benefit by the socket aperture 11 of last 1 upper end.Cooperate with last 1 lower end concavo-convex 13 concavo-convex 21 made in the upper end of following part 2, part 1 and the 2 concavo-convex cooperations of following part docked, and finally fixed by the housing of connector body, the socket aperture 11,26 that makes upper and lower pieces over against.The socket aperture middle part of following part 2 is shaped on necking part 22, it forms respectively up and down tops bar 23 and get out of a predicament or an embarrassing situation 24, the size that leaves clearance D with the socket external diameter is made in the aperture of the socket aperture 26 of necking part top, stepped hole is made in the bottom of the socket aperture 25 of necking part 22 belows, the aperture of socket aperture 25 cooperates with socket afterbody 34 external diameters, the degree of depth in hole is also alignd with the jack tail plane, and socket 3 afterbodys 34 are axially limited, and eliminates the phenomenon that radially wobbles of socket 3 tops and afterbody thus.During mounting receptacle body 3, with socket 3 bottom of part 2 insertion down certainly, top bar 23 until what skirt lobe 31 lower edges of socket 3 were stuck in socket aperture middle part, the fin 33 of socket 3 is stuck in gets out of a predicament or an embarrassing situation 24, the necking down position 32 of socket is just engaged with the necking down position 22 at following part 2 middle parts, guaranteed that socket 3 can not axially jump, increased the detent force (important parameter of weighing the connector inserts positioning performance) of socket effectively.Like this, the top of socket 3 is fixed by last insulating part, afterbody is fixed by following insulating part, the insulating part unification by its position of the fixedly connected assurance of concavo-convex tenon more up and down, improvement through above measure, the stationkeeping ability of socket 3 is guaranteed, and the position of looking for of contact pin is forbidden, and phenomenons such as the withdraw of the needle are eliminated substantially.

With reference to Fig. 4, the size that leaves clearance D with socket 3 external diameters is made in the aperture of the socket aperture 26 of following part 2 necking parts top, when needs dismounting socket 3, socket wrench specially adapted for it shape instrument 6 inserts from clearance D, and the skirt lobe 31 that forces socket 3 draws in and leaves and top bar 23, socket 3 can be ejected downwards.
