A kind of board to board connector

Technical field

The present invention relates to a kind of interconnective board to board connector between the various boards that is used for.

Background technology

In electric equipment, general passing through connects different circuit boards, thereby finishes the transfer of data between circuit board.Existing board to board connector comprises male plug part and mother board, wherein, male plug part and mother board respectively have sleeve male seat and sleeve female seat, the sleeve male seat has male plug part slot, wherein be plugged with male plug part terminal, the storage tank that the sleeve female seat has the mother board slot and plants and use for the sleeve male seat, the mother board slot is plugged with the mother board terminal, male plug part and mother board insert storage tank by the sleeve male seat and form described board to board connector, male plug part terminal and the mother board terminal that engages with it have two rows respectively, and the linking of circuit is promptly formed by male plug part terminal and mother board terminal overlap joint.

Because more and more to the miniaturization development, volume of transmitted data is increasing for the development trend of present electronic product, the number of terminals of required connector is more and more.Therefore, in order to satisfy the demand for development of electronic product, the length of the board to board connector of said structure is just done more and more longlyer, and this causes the intensity of connector and rigidity all to decrease accordingly.And aspect production technology, long its flatness of board to board connector is also wayward, has increased the surface mounting technology difficulty of (Surface mounting technology is called for short SMT), causes the product fraction defective to rise.

Therefore, reduce length, raising utilization of space, the improve processing and the production technology of board to board connector how, aspects such as assurance flatness have proposed higher designing requirement to board to board connector.

Summary of the invention

The technical problem that the embodiment of the invention will solve is, a kind of board to board connector is provided, and is intended to solve that board to board connector length is long, area is excessive, and utilization of space is low, and flatness is wayward, and SMT paster difficulty is big, the problem that fraction defective is high.

The embodiment of the invention is to realize like this, a kind of board to board connector, comprise male plug part and mother board, the male plug part has the sleeve male seat, set male plug part slot in the sleeve male seat in a row, wherein be plugged with male plug part terminal, mother board has the sleeve female seat, set the mother board slot in the sleeve female seat in a row, be plugged with the mother board terminal in the mother board slot, and form the storage tank of planting and using for the sleeve male seat between adjacent two row's mother board slots, male plug part and mother board insert storage tank by the sleeve male seat and form described board to board connector, male plug part terminal and mother board terminal engage forming circuit and connect, and male plug part terminal is at least three rows, and the mother board terminal that engages with it has the respective row number.

Technique scheme owing to change the arrangement of board to board connector terminal at least three rows by existing two rows, greatly reduces the length of board to board connector, has improved utilization of space.And, by reducing board to board connector length, can effectively control its flatness, also reduced the paster fraction defective of SMT simultaneously, reduced production cost.

Embodiment

In order to make the technical problem to be solved in the present invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

To shown in Figure 6, shown a kind of board to board connector provided by the invention as Fig. 1, it comprises male plug part 1 and mother board 3.

Described male plug part 1 has sleeve male seat 10 and male plug part terminal 20.Have the male plug part slot 11 that four rows be arranged in parallel on this sleeve male seat 10, male plug part terminal 20 is inserted in the male plug part slot 11.Each male plug part terminal 20 has the two ends arm, and wherein an end arm is a contact arm 201, and other end arm is a conducting arm 203, and contact arm 201 is connected with the registration arm 202 of conducting arm 203 by a bending.Contact arm 201 is connected electrically in (not shown) on the circuit board, and conducting arm 203 is embedded in the male plug part slot 11, to cooperate (seeing aftermentioned for details) with mother board 3.

Described mother board 3 has sleeve female seat 30 and mother board terminal 40.Have the mother board slot 31 that four rows be arranged in parallel on this sleeve female seat 30, form storage tank 34 between adjacent two row's mother board slots 31, plant for male plug part 1, mother board terminal 40 inserts in the mother board slot 31.Each mother board terminal 40 has the two ends arm, and wherein an end arm is that contact arm 401, other end arm are conducting arm 403, and contact arm 401 is connected with the registration arm 402 of conducting arm 403 by a bending.Contact arm 401 is connected electrically in (not shown) on another piece circuit board, conducting arm 403 stretches out the mother board slot 31 outer conductive contacts 404 that form with the connecting portion of registration arm 402, when male plug part 1 was inserted on the mother board 3, conductive contact 404 was connected to that forming circuit connects on the conducting arm 403 of male plug part terminal 20.Certainly, above-mentioned male plug part terminal 20 also can be other version well known in the art with mother board terminal 40, connects as long as both overlap forming circuit mutually.

Male plug part terminal 20 is four rows in the present embodiment, and mother board terminal 40 has corresponding four rows with matching.Certainly, as required, row's number of male plug part terminal 20 and mother board terminal 40 also can be for three rows or more than three rows.Like this, greatly reduce the length of board to board connector, improved utilization of space.And, by reducing board to board connector length, can effectively control its flatness, also reduced the paster fraction defective of SMT simultaneously, reduced production cost.

The two ends of above-mentioned sleeve male seat 10 and sleeve female seat 30 also have

block

13,33 respectively, the position at corresponding each row's male plug part slot 11 two ends outwards convexes with respectively and is embedded piece 12 on the block 13, and the corresponding position that is embedded piece 12 is recessed to form downwards and is embedded groove 32 on the block 33.Male plug part 1 and mother board 3 during sleeve, are embedded piece 12 and are embedded groove 32 chimeric location mutually, make male plug part 1 combine more firmly with mother board 3.
