Abstract

The utility model relates to a wire pressing insulator which comprises an insulator body; a central probe installation slot is arranged on the insulator body and provided with a slot segment with a U-shaped cross section profile; and the U-shaped structure comprises two parallel wires and a major arc which is connected at one ends of the two parallel wires in the same direction. In the technical scheme of the wire pressing insulator, the cross section of the central probe installation slot takes the shape of a structure with a major arc at the bottom and a group of parallel wires on the top. When in use, a contactor is pressed into the major arc at the bottom from a notch formed by the two parallel wires; the major arc holds the contactor and stops the contactor from falling off the insulator; in addition, the major arc also can fix the position of the contactor; and the contactor is fixedly held in the insulator and never shakes. Therefore, the contactor and the insulator are inserted into the external contactor of the connector conveniently, thereby improving the assembly efficiency.

Description

A kind of line ball insulator

Technical field

The utility model relates to a kind of connector, especially a kind of line ball insulator of connector.

Background technology

At present, a kind of like this connector is arranged on the market, in the housing of this connector differential contact elements is installed, shown in Fig. 1,4, differential contact elements comprises outer pin 13, center needle 10, front insulator 11, line ball insulator 1 and line ball cover 12, upwards is provided with the center needle mounting groove 2 that cross section is the U type week of line ball insulator 1.When the assembling differential contact elements, need earlier center needle 10 to be placed the center needle mounting groove 2 of U type, the week of line ball insulator upwards is to be provided with a plurality of center needle mounting grooves 2 simultaneously to assemble a plurality of center needles 10 generally speaking, because 2 pairs of center needles 10 of center needle mounting groove of U type do not have holding function, when laying a plurality of center needle 10 on the line ball insulator 1 simultaneously, with line ball insulator 1 and center needle 10 and front insulator 11 assemblings the time, be difficult to guarantee that center needle 10 does not come off, also have, 2 pairs of contacts of the center needle mounting groove of U type do not have fixed function, be difficult to guarantee that center needle 10 is in suitable rigging position, when if contact is not in optimum assembling position then be difficult to center needle 10 is interted in the front insulator 11 smoothly, brought very big inconvenience to installation like this, efficiency of assembling is lower.

The utility model content

The purpose of this utility model provides a kind of line ball insulator, in order to solve existing line ball insulator contact is not possessed holding function, and is relatively more difficult when the assembling connector, ineffective problem.

For achieving the above object, the utility model adopts following technical scheme: a kind of line ball insulator, comprise insulator body, insulator body is provided with the center needle mounting groove, described center needle mounting groove has the groove section that cross-sectional profiles is analog-U shaped structure, and described analog-U shaped structure comprises the major arc that the unidirectional end of two parallel lines and two parallel lines is connected.

The center of circle of described major arc is positioned on the center line of described two parallel lines.

The diameter of the contact that diameter and its held of described major arc is corresponding to the same.

The line ball insulator of such scheme, the cross section bottom of its center needle mounting groove is a major arc, the top of major arc connects one group of parallel lines, the notch that contact is constituted from two parallel lines during use is by the major arc of compressing into the bottom, major arc has containment role to contact, prevented that contact from coming off in insulator, in addition, major arc also has the effect of location when contact is contained, this moment contact be fixed clamp among insulator, the phenomenon that can occur rocking has not guaranteed that center needle is on the best rigging position, be convenient to center needle intert smoothly differential contact elements into outer pin in, improved efficiency of assembling.

Embodiment

Fig. 2, shown in Figure 3, line ball insulator of the present utility model, comprise

insulator body

3,3 weeks of insulator body upwards evenly are provided with four center needle mounting grooves 6 along the insulator body longitudinal extension, center needle mounting groove 6 connects the front/rear end of insulator body 3, one end of this center needle mounting groove 3 is the groove section that cross-sectional profiles is analog-U shaped structure, described analog-U shaped structure comprises the major arc 5 that the unidirectional end of two parallel lines 4 and two parallel lines is connected, the diameter of the contact that diameter and its held of major arc 5 is corresponding to the same, in addition, the center of circle of this major arc 5 is positioned on the center line of described two parallel lines 4.
