Abstract
The utility model relates to a U-type contact female header connector which comprises a plastic body and terminals. A plurality of plastic holes are arranged inside the plastic body. The terminals pass through the plastic holes to be connected with the plastic body. Each terminal is provided with a first pin, a second pin and a third pin that is symmetrical to the second pin. A bottom end of the first pin is provided with a chamfer. Both the second pin and the third pin are provided with two plane structures which are connected via an arc. A rubber core is disposed on a side surface of each plastic hole. The rubber core is equipped with an inverted chamfer to correspond to the chamfer on the bottom end of the first pin. The beneficial effects of the U-type contact female header connector are that a unique design of the chamfer and the inverted chamfer helps to prevent the terminals from being exposed; high contact force is generated between each rubber core and a horn-shaped opening structure design formed by each second pin and each third pin, thereby preventing the rubber core from being drawn out; and each terminal is equipped with the two plane structures connected via the arc, so that each rubber core is not liable to crack and holding force of the terminals is substantially enhanced by a reversal mechanism.
Description
Technical field
The utility model relates to a kind of row's female connectors of U-shaped contact.
Background technology
Development along with science and technology, the high-end fields such as intelligent electric meter, industrial computer and communication apparatus equipment are all in continuous development, particularly in the intelligent electric meter industry, connector is a kind of necessary base components, it plays a kind of effect that connects and transmit in each electrical equipment and parts, this connector must guarantee that also contact is good except satisfying these key propertys, reliable operation, maintenance is convenient.The phenomenons such as end, male extract that rear glue core comes off and the terminal confining force is little often appear revealing in present on the market connector, because these bad phenomenon just can cause depot repair, have greatly increased the workload of producer, have reduced operating efficiency, have expended the manpower financial capacity.
The utility model content
The purpose of this utility model provides a kind of row's female connectors of U-shaped contact, to overcome that appearance that present prior art exists reveals that end, male extract that rear glue core comes off and the terminal confining force depot repair that causes such as little, greatly increased the workload of producer, reduce operating efficiency, expended manpower financial capacity's deficiency.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of row's female connectors of U-shaped contact comprises plastic body and terminal, is provided with several plastic cement holes in the described plastic body, and described terminal passes plastic cement hole connection plastic colloid; Described terminal be provided with first pin, second pin and with second the 3rd pin that pin is symmetrical, described first sole end is provided with chamfering, be equipped with the first plane and the second plane on second pin and the 3rd pin, the first plane be connected the plane and connect by circular arc; Side, described plastic cement hole is provided with the glue core, and the chamfering corresponding position of glue core and first sole end is provided with instead angle.
Further, described second pin and the 3rd pin form the horn opening structure, and described glue core and second pin and the 3rd pin contact position are provided with and add glue-line; Bottom, described plastic cement hole is interspersed with public pin, and described public pin passes described horn opening structure and contacts with terminal; Described first pin and second pin contact with the glue-line that adds of glue core.
The beneficial effects of the utility model are: the utility model is provided with chamfering and the unique design at angle instead, has prevented the generation that terminal reveals the end situation; Bell-mouthed design on the terminal makes horn mouth and glue core produce larger contact force, has prevented that the phenomenon that the glue core is taken out of from occuring; Terminal is provided with two planes, and is provided with a circular shape that falls between two planes, and such design not only is difficult for causing glue core cracking, and can also make reversing-gear increase greatly the confining force of terminal.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.

Fig. 4 is the transverse sectional view of row's female connectors of the described a kind of U-shaped contact of the utility model embodiment when using state.
Among the figure:
1, plastic body; 2, terminal; 3, glue core; 4, plastic cement hole; 5, first pin; 6, second pin; 7, the 3rd pin; 8, chamfering; 9, the first plane; 10, the second plane; 11, circular arc; 12, angle instead; 13, public pin.
Embodiment
Shown in Fig. 1-4, row's female connectors of the described a kind of U-shaped contact of the utility model embodiment comprises plastic body 1 and terminal 2, is provided with several plastic cement holes 4 in the described plastic body 1, and described terminal 2 passes plastic cement hole 4 connection plastic colloids 1; Described terminal 2 is provided with first pin 5, second pin 6 and three pin 7 symmetrical with second pin 6, described first pin 5 bottoms are provided with chamfering 8, be equipped with the first plane 9 and 10, the first planes 9, the second plane on second pin 6 and the 3rd pin 7 and be connected plane 10 and connect by circular arc 11; 4 sides, described plastic cement hole are provided with glue core 3, and glue core 3 is provided with instead angle 12 with chamfering 8 corresponding positions of first pin 5 bottoms; Described second pin 6 and the 3rd pin 7 form the horn opening structure; Described glue core 3 and second pin 6 and the 3rd pin 7 contact positions are provided with and add glue-line; 4 bottoms, described plastic body 1 interior plastic cement hole are interspersed with public pin 13, and public pin 13 passes described horn opening structure and contacts with terminal 2.
During concrete the use, terminal 2 is inserted in the middle of the plastic cement hole 1 in front 1 the inside, plastic cement hole that first the auxiliary type pin is inserted into of insertion terminal 2 again, instead matches at 10 places, angle with glue core 3 when being inserted into certain depth rear terminal 2 chamferings 8, this moment in any case, the end situation can not appear revealing in terminal 2, can conveniently use.
When Product jointing behind pcb board, public pin 13 is inserted in the plastic cement hole 1, thereby after flicking, the horn opening structure that adopts second pin 6 and the 3rd pin 6 to form directly contacts the larger contact force of generation with the glue-line that adds of glue core 3, so when public pin 13 is extracted, glue core 3 is held by second pin 6 and the 3rd active force that pin 7 is produced always, so just can not cause glue core 3 to come off, guarantee product quality.
The utility model adopts the biplane interference mechanism, and first plane 9 is connected by the circular arc 11 that falls in second plane 10, in the time of in being inserted into plastic cement hole 1, first plane 9 will be interfered with glue core 3 this moment, it can occur expanding glue core 3 in the situation of interfering, the unnecessary material that expands flows to circular arc 11 shapes that fall in just, the material that expands unnecessary forms a reversing-gear after flowing to circular arc 11 shapes that fall in, such design is difficult for causing glue core 3 crackings, can also make reversing-gear increase greatly the confining force of terminal 2, guaranteed the normal operation of connector, easy to use, not fragile.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
