Abstract

The utility model relates to a female header connector including a rubber core and a plurality of terminals. PIN holes having the same number with the terminals and distributed evenly are arranged in the rubber core. A terminal fixing groove is arranged in a position near an edge of the rubber core and in an upper part of each of the PIN holes. A guide block is arranged in the middle of each of the PIN holes. A lower end of each of the terminals is provided with two terminal springs connected mutually. Both of the two terminal springs of each of the terminals bend inward to form an arc-shaped structure. Terminals go through the fixing grooves and are fixed in the PIN holes through the terminal springs and the guide blocks. The female header connector in the utility model has beneficial effects: a connection method of the terminals and male head terminals is changed from a side contact of material terminal springs with the male head terminals into a front contact of the material terminal springs with male head terminals. Thus, the contact performance of the socket of the male head terminals and the female head terminals and the service life time of the female header connector are improved, resistance and contact impedance generated in the inserting of the male head are reduced, thereby making the transmission more stable. Since the guide blocks are arranged in the PIN holes, the terminals can be guided in inserting and terminal inserting through holes having the same size can be obtained, thereby guaranteeing the strength balance in inserting.

Description

A kind of row's female connectors

Technical field

The utility model relates to a kind of row's female connectors.

Background technology

This type of product terminal in the market is the pure blanking formula of a mould structure; Normally contact conducting with public head, and the blanking side of material is because there is the blanking clearance in mould, burr, burr, the blanking bad problems such as angle of collapsing must occur with the blanking side of material; So this kind contact exists contact area little; Be prone to wipe off the shortcoming of terminal surfaces coating, make terminal more be prone to aging and elastic failure, thereby make the bigger of contact impedance change.

The utility model content

The purpose of the utility model provides a kind of row's female connectors, has improved the use life of public mother to slotting contact performance and product, has reduced resistance and contact impedance that public head inserts, makes transmission more stable.

The purpose of the utility model is to realize through following technical scheme:

A kind of row's female connectors; Comprise glue core and plurality of terminals; The glue in-core is provided with evenly distributed and identical with number of terminals PIN hole, and top, PIN hole is provided with terminal fixing grooves near glue core edge, and the middle part is provided with guiding block in the said PIN hole; The terminal bottom is provided with interconnective two-terminal shell fragment, and terminal passes holddown groove and is fixed in the PIN hole through two-terminal shell fragment and guiding block.Said two-terminal shell fragment all bends to the width that distance between arcuate structure and the two-terminal shell fragment equals guiding block to the inside, and guiding block is clipped between two terminal shell fragments.

The beneficial effect of the utility model is: the contact form that has changed terminal and public head end; Becoming material terminal shell fragment front surface by the terminal shell fragment contacts side surfaces of material contacts with public head; Improved the use life of public mother, reduced resistance and contact impedance that public head inserts, made transmission more stable slotting contact performance and product; PIN is provided with guiding block in the hole; Correcting and the terminal that obtains identical size inserted conducting orifice when terminal was inserted, and had kept good axiality when inserting with public head, the balancing in power property when having guaranteed to insert.

Description of drawings

According to accompanying drawing the utility model is done further explain below.

Fig. 1 is the described a kind of structural representation of arranging female connectors of the utility model embodiment;

Fig. 2 is the described a kind of structural representation of arranging terminal in the female connectors of the utility model embodiment;

Fig. 3 is the described a kind of partial sectional view of arranging female connectors of the utility model embodiment.

Among the figure:

1, glue core; 101, PIN hole; 102, terminal fixing grooves; 103, guiding block; 2, terminal; 201, terminal shell fragment.

Embodiment

Shown in Fig. 1-3; The described a kind of row's female connectors of the utility model embodiment; Comprise glue core 1 and plurality of terminals 2; Be provided with evenly distributed and identical with terminal 2 quantity PIN hole 101 in the glue core 1,101 tops, PIN hole are provided with terminal fixing grooves 102 near glue core 1 edge, and the middle part is provided with guiding block 103 in the said PIN hole 101; Terminal 2 bottoms are provided with interconnective two terminal shell fragments 201, and terminal 2 passes terminal fixing grooves 102 and is fixed in the PIN hole 101 through two-terminal shell fragment 201 and guiding block 103.Said two-terminal shell fragment 201 all bends to arcuate structure to the inside, and the distance between the two-terminal shell fragment 201 equals the width of guiding block 103, and guiding block 103 is clipped between two terminal shell fragments 201.

During concrete the assembling; The terminal 2 that will have strip earlier inserts in the PIN hole 101 of glue cores 1, through machine terminal 2 is pressed in the glue core 1 then, and the harmony when guaranteeing that through guiding block 103 terminals 2 insert; After terminal 2 is pressed into strip is dismissed, checked finished product and packing warehouse-in at last.

The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection range of the utility model.
