Description

A contact type electrical connector

technical field

The invention relates to a connector, in particular to a contact type electrical connector.

Background technique

As an important component of modern signal transmission, connectors have increasingly high performance requirements for their respective applicable occasions. The traditional structure of pin and socket connectors is limited by the pin-hole insertion method, and the axial length of the connector, As well as the size and accuracy of the pinhole joint surface, etc., directly affect its performance, and the applicability of the occasion is limited.

SUMMARY OF THE INVENTION

The invention provides a contact type electrical connector with simple structure, which can meet the needs of plugging in a small size in the axial direction, has a large plugging joint surface, and is beneficial to improve the transmission performance.

The technical solution adopted in the present invention is: a contact type electrical connector, including a socket and a plug, and is characterized in that: the plug-in end surface of the socket housing is provided with more than one socket with an outward opening and a spherical concave structure. The socket part, the pin insulator in the head shell of the plug is connected with a plurality of pin parts corresponding to the socket part, and the head of the pin part protruding from the pin insulator is a ball with a spherical concave structure corresponding to the socket part The head structure, the pin part includes a pogo pin and a pin seat, the pogo pin and the pin seat are inserted in the connecting cavity in the middle of the pin insulator and a compression spring is covered in the connecting cavity, and the compression spring is pressed against the pogo pin and the connecting cavity between the rear.

Further, the tails of the pogo pins are fitted and socketed on the pin holder.

Further, the pogo pin and the pin holder are partly provided with a sheath in the passage cavity in the middle of the pin insulator, and the sheath covers the pressure spring.

Further, the pin part is a fur button structure.

The present invention improves the traditional axially longer pin and jack insertion structure into a shorter, larger contact surface, and more stable ball head and spherical concave structure, which is beneficial to simplify the axial length of the connector and meet the Axial small size plugging, the requirements of large plug joint surface can further improve the transmission performance.

Detailed ways

Further description will be made below in conjunction with the accompanying drawings.

As shown in Figures 1-4, a contact type electrical connector includes a plug 1 and a socket 10. The head shell 2 of the plug 1 is provided with a pin insulator 3 and a pin insulating cover that is press-fitted by a rear pressure plate 5. The pin insulation assembly composed of board 4, the pin insulation assembly is connected with a plurality of pin parts corresponding to the socket parts, the pin parts include pogo pins 6 and pin holders 7, and the pogo pins extend out of the head of the pin insulator For the ball head structure corresponding to the spherical concave structure of the jack, the pogo pin and the pin seat are plugged in the connecting cavity in the middle of the pin insulation assembly and the sheath 8 is covered, and the sheath 8 is covered with the compression spring 9, and the compression spring is tight. Between the pogo pin and the rear of the threading cavity. The socket housing 11 of the socket 10 shown in Fig. 3 and 4 is provided with one or more jacks 12 opening outwards and having a spherical concave structure on the mating end surface, and a sealing ring 14 is provided on the mating end surface of the housing housing. 1 When plugged in, the pogo pin ball head structure corresponds to the contact type engagement of the socket part 12. In FIG. 3 , the socket member 12 is not shown connected to the upper end surface due to the sectional view. In the art, the socket member 12 must extend to the upper insertion end surface.

In the above-mentioned embodiment, more than one connection insert 13 is provided on the mating end surface of the seat housing, and the connection insert is used for guiding insertion when assembling with the short-circuit cover of the socket.

On the basis of the above embodiments, any pin insert can be replaced with a fur button structure, which belongs to the conventional technology of fur button connection, and will not be described in detail in this application and the embodiment.
