A connector assembly comprises a straddle connector including a dielectric housing having a front face forming an island section and a rear face opposite the island section. Upper and lower rows of terminals are embedded within the housing. Each terminal includes a connecting section extending to the island section and a tail section extending beyond the rear face. A retaining slot is defined between the upper and lower rows of tail sections. A PCB having upper and lower rows of golden fingers is inserted into the retaining slot. Each golden finger of one of the upper and lower rows is coated with solder paste. A row of holes is defined in the PCB adjacent to the golden fingers. Each hole is aligned with the extension of the corresponding terminal and has a solder drop disposed therein.

Method for performing double-sided SMT

A board lock includes a base section fixed to an electrical device, such as a connector, and an elastically diameter-contractible barrel section extending from the base section beyond a face of the electrical device. The barrel has an external threading. The barrel has a section of nominal diameter substantially equal to or greater than an inner diameter of a hole defined in a circuit board whereby the barrel is elastically contractible to be inserted into the hole which generates a spring-back force driving the external threading to engage with the inner diameter thereby securing the electrical device to the substrate.

Board lock

A printed circuit board mounted connector which employs separate fasteners for securing the connector to elongate mounting holes of the board. The fastener has an upper cap and a lower non-circular threaded rod. The insulative housing of the connector has a pair of side flanges. Each flange has a stepped through-hole, consisting of an upper hole for receiving the upper cap of the fastener and a lower non-circular hole for receiving the lower non-circular threaded rod of the fastener, and a number of protrusions on an interior wall of the upper hole. The protrusion has an inclined top surface which assist in a turning movement of the upper cap of the fastener within the upper hole of the flange. The lower non-circular threaded rod is dimensioned to be rotatable about a certain angle within the lower non-circular hole of the flange until contacting and thus engaging an interior wall of the lower non-circular hole.

Fastener for a printed circuit board mounted connector

A board lock includes an outer member defining a central hole for receiving an inner member therein. The outer member has a plurality of resilient legs which are expanded by insertion of the inner member. The outer member is received in holes defined in an electrical connector and a printed circuit board. The expansion of the legs causes the legs to engage with an inner surface of the hole of the printed circuit board thereby securing the connector to the printed circuit board. The legs of the outer member are provided with threading which provides an effective and secure engagement between the legs and the hole. Securing the board lock to the circuit board by means of the engagement between the outer member and the inner surface of the hole, together with the resiliency of the legs, allows the board lock to be fixed to holes of different sizes and depths.
